Summary of the key points of the installation details of the sun panel in the greenhouse

 Sunshine board (PC board), also known as ring steel, is a material for high-quality plastic products. Due to its many advantages, it is widely used in agricultural production. Today Plastic Sheet manufacturers introduce the details and specifications of their installation on the top of the glass greenhouse and the top of the solar panel greenhouse.




First of all, we need to understand that the solar panel for agricultural production is installed on the triangular surface on the top of the glass Greenhouse. It has a certain slope on the top. Rain, snow and dust falling on it will fall into the tank along the slope. Therefore, we need to pay attention to the following items when installing




1. The front and back of the sun panel


  Because the solar panel is used on the greenhouse, it will take into account the problems of externally resisting ultraviolet rays and internally dripping and defogging. In order to solve these two problems, the agricultural greenhouse solar panel will add a layer of anti-ultraviolet UV coating on the front side during production, which greatly prolongs the service life of the solar panel. The inner surface of the agricultural sun board is also added a layer of coating to allow water to flow into the dew collecting tank along the slope of the sun board. The function of this coating is to drip and defog. Therefore, when installing, keep in mind that the front side of the solar panel is upward, otherwise it will seriously affect the service life of the solar panel.




2. The length and width of the sun panel


In consideration of its light transmittance, the greenhouse solar panels for agriculture generally use 8mm double-layer hollow panels, and the light transmittance is about 80%. The composition of agricultural to solar panels is arranged in long strips. In normal installation, the strip direction is the length of the solar panel, and the direction in which the strips are arranged is the width of the solar panel. Therefore, when we customize agricultural sun panels, the commonly used model is 1.95m as the width, and the length is customized according to the length measurement of the purlins in the agricultural greenhouse. The length and width of solar panels in agricultural greenhouses affect their curvature, load and lifespan.




3. The edge of the sun panel is wrapped


Above we know that the double-layer hollow solar panel used in agriculture is composed of long strips, and the top and bottom of each strip are the same. We need to wrap the holes at both ends of the solar panel with aluminum foil paper tape before installing the panel. In this way, a closed space is formed inside the strip, and external dust and water vapor will not go inside. If the installer omits this process, the interior of the solar panel will be easily dirty in the later stage, and the interior cannot be cleaned, which will seriously affect the light transmittance and service life of the solar panel.




4.


The installation of polycarbonate sheet uses neutral silicone glue, which will not cause corrosion to the sheet. Long service life and good sealing performance.




The installation of professional agricultural glass greenhouse sunlight panels requires a professional construction team.

The decorative effect of the PC board is amazing!

 As early as the end of the 20th century, the concept of light dispersion materials was proposed. Light dispersing materials refer to materials that can not only pass light through but also effectively scatter light. It can convert point light sources into line light sources or convert line light sources into surface light sources, and can be used as surface light source materials for cold light sheets, guides, etc. Light panels, backlight devices and liquid crystal displays and other equipment.




This is because the light dispersant in the light dispersing material is evenly distributed. When the point light source of the LED passes through the light dispersing material, it will produce many refraction, reflection, scattering and other phenomena when encountering dispersant particles and media with different refractive indices. Make the light evenly pass through the material without exposing the lamp beads, achieve the uniform transformation from point light source to surface light source, and obtain the effect of optical dispersion.




Polycarbonate sheet is widely used to process LED lampshades and light-dispersing sheets because of its excellent mechanical properties, such as aging resistance, no cracking, and high heat distortion temperature. The material used in the lighting project is a new type of green petroleum derivative - PC board. The PC board is processed into "oil and gas pipelines", which are crisscrossed and "woven" to form the building shell, and then the specially distributed LED point light sources are hidden in the PC shell. Inside, the PC shell is evenly illuminated by means of internal light and external transmission, forming a beautiful special effect, and any colorful video image can be displayed through the control system. The number of LED point light sources in the lighting project of the Shanghai World Expo Petroleum Pavilion, the use of PC boards as the light receiving carrier to realize the video display method of internal light and external transmission, and the screen layout have all created the world's first.




The huge oval LED display wall in the London Museum uses transparent PC tubes as the protective lampshade for the LED units. The transparent material is a polycarbonate material produced in line with the development trend. Its unique weather resistance such as ultraviolet resistance makes it widely used in the optical field. The lampshade made of this material for the LED display wall of the London Museum has high light transmittance, which can ensure that the light is effectively concentrated and directional.




However, although the traditional optical-grade PC Sheet has a certain dispersion power for point light sources, it is far from meeting the growing demand for its use in the LED field. Therefore, light dispersion materials based on PC sheets have gradually entered the market. The stage of the new material.




Light dispersing PC board is obtained by uniformly dispersing light dispersant in Plastic Sheet. It has excellent light dispersion, light transmittance and outstanding UV stability, and is widely used in the LED industry.




The principle of light dispersion is: when the light hits the surface of the light-dispersing PC sheet, because the refractive index of the PC resin and the light-dispersing agent are different, the light is reflected like a mirror on the surface of the light-dispersing agent, and after repeated reflections, the light-dispersing effect is achieved. At present, light-dispersing PC sheets have attracted extensive attention from scientists at home and abroad, and have already been used commercially. Some famous companies have developed related products and won a wider market.

Why does the PC endurance board continue to seep after it is sealed?

 Why does the PC endurance board continue to seep after it is sealed?

In the rainy season, why does the PC solid sheet continue to seep after it is sealed?

Polycarbonate sheet is applied to the roof of the building, the roof of the bus shelter, the curtain wall, the parking shed, the awning, and the vegetable greenhouse. In many parts of the country, it is completed by the construction and installation of some small engineering design companies. Because its PC endurance board and PC sun board have many characteristics, it will cause some construction quality problems after the completion of the project, such as airtightness. There are thousands of reasons for the water seepage of PC endurance boards and PC sun panels. The following are some of the reasons we need to meet when fighting customers:


1. Sealant type. In the process of business process exchange, we have encountered that the reason for the water seepage of many projects is the sealant. The requirements for the sealant of PC endurance board and PC sun board are very strict, and the most important point is neutrality. Silicone rubber, many customers do not meet the natural environment, and use strong acid and alkali structural adhesives, which lead to incompatibility with PC endurance boards, resulting in water seepage of bad boards; another reason is the use of fake and inferior sealants, because The sealant sales market is also very chaotic. Many consumers do not know which sealants are good for sealing, which leads to poor airtightness of PC boards and decorative strip units.


2. The index in the middle of the pre-embedded PC board is not enough. We know that the most important feature of PC endurance boards and PC solar panels is thermal expansion and contraction, and a space for thermal expansion and cold contraction must be embedded between the panels.

Reasonable maintenance methods for Solid Polycarbonate Sheet

 Reasonable maintenance methods for Solid Polycarbonate Sheet

1. Before installation, be sure to install the side of the protective film with the packaging and printing mark facing outward.

2. Before installation, do not take off the protective film to avoid scratching the board during the installation process. Only lift the protective film about 50 mm along the edge of the board. After the installation, immediately take off the protective film. If you want to maintain the surface again, take it off first Film, and then cover the protection again, be sure to avoid using a sharp knife to remove the protective film, otherwise it is easy to cause the board to crack when it is bent.

3. When installing, a neutral sealant should be used, and it must be tested whether it is a special sealant compatible with the pc solid sheet before use. Do not use colloidal solutions with pH.

4. The pc endurance board can be cold-drawn into arcs with different bending radii along the direction of the rib. The pc endurance board with different thicknesses is cold-drawn and the minimum bending radius is 175 times the thickness of the plate. If the actual bending radius of the plate is less than the limit bending, The board is easy to crack, and the company does not provide any quality guarantee for installation beyond the bending radius.

5. When the installation must be drilled on the board, a small round hole must be drilled first, and then gradually expanded to the required diameter. The size of the punching hole away from the edge of the board is not less than 40mm. The diameter of the punching hole should exceed 50% of the diameter of the anchor bolt to accommodate the thermal expansion and contraction of the plate.

6. Do not touch the surface with acids, alkaline substances and adhesive solvents, such as alkalis, alkaline salts, amines, ketones, aldehydes, acids, ethers, halogenated hydrocarbons, and acid-base structural adhesives.

7. The panels cannot be covered or overlapped for installation. Due to the higher internal stress caused by the thermal expansion and contraction of the stacked panels, it is more likely to cause cracks and seams of the panels.

8. Solid Polycarbonate Sheet manufacturers installation method: detailed installation manual, the following aspects need attention


A. When the outdoor equipment or the temperature difference is above 8°C, the diameter of all anchor bolts and bolt holes must be increased to allow the pre-embedded amount of temperature expansion and contraction. Generally, the diameter must exceed 50% of the diameter of the anchor bolt.

B. All the main bones should be covered with neutral glue in the gap, and the exposed part should be coated with neutral glue to prevent the rivet head from pressing the surface immediately and reduce the pressure.

C. The upper screw cannot be too tight, otherwise it will cause ground stress. Screws must be added with washers or washers to prevent local damage to the board due to high air pressure.

D. PVC gaskets and waterproof tapes with bitumen components cannot be used.

E. On the long side and the long side, you add metal decorative strips, and pre-buried expansion gaps to increase the fixing power.

F. When drawing and processing, the bent part should not be fixed with screws, otherwise it is easy to break.

9. If there is adhesion of caulking material, vegetable oil, building paint, etc., when the environment pollutes the surface of the PC board, try to remove it with a thin cloth dipped in alcohol before it hardens. Do not wash with benzene, motor gasoline, toluene or carbon tetrachloride, and avoid cleaning with organic solvents when exposed to sunlight or during construction of mandatory bending projects, otherwise cracks will occur. Dust and waste on the surface of the PC board are generally wiped with a soft plastic cloth or sponge dipped in a neutral cleaning solution, then thoroughly washed with cold water, and then wiped with a soft plastic cloth.

10. Storage and transportation of PC boards:

During the transportation process, avoid placing hanging objects on the polycarbonate sheet, and do not touch the sheet with needle stab wounds: mechanical equipment should be used for loading and unloading of waterproof membranes, or use the starting point of the vehicle and the springboard to unload carefully. In addition, the PC board should not be exposed to the outdoors for storage, and should be placed in a cool place.

11. PC sheet cleaning:

Small area cleaning: wash with warm water;

Wash with neutral soap or household detergent mixed with warm water, and use a soft fabric or sponge to remove dust and stains; wash with cold water and wipe off the dry spots with a thin cloth after drying.

Large-scale cleaning: cleaning with tap water or high-pressure water pump;

Additives in water should be compatible with PC board.

Cleaning FAQ:

Do not polish or clean the PC Sheet with strong acid, and do not wipe the surface with a dry hard cloth or a hard or soft brush to avoid calendering.

It is forbidden to use butyl cellosolve and other water retention solutions to clean PC sheets that block ultraviolet rays.

Suggested organic solvents for cleaning:

Absolute ethanol, petroleum ether (BP65), hexane, conane. To prevent the PC sheet from coming into contact with immiscible compounds.

What are the commonly used insulation materials for purification panels?

 The application of the purification board has become more and more extensive, so what are the insulation materials commonly used for the purification board? Next, follow FRP Panel suppliers to find out.

       Purification board is a common building material in clean rooms, and it is also an insulation material often used by builders. Purification board has now become the mainstream material for building wall insulation.

       Commonly used thermal insulation materials for purification panels are: rock wool, glass fiber cotton, polystyrene, polyurethane, etc., with low thermal conductivity, so that the prefab room has good thermal insulation effect.

       FRP Panel manufacturers use these heat preservation materials, the purification board has a good heat preservation and heat insulation function, the quality of the product determines the use time and safety guarantee, some must not be greedy for cheap and choose irregular manufacturers, we usually use it on the Internet We can see some tragic accidents caused by choosing unqualified manufacturers to use unqualified products, so we must choose regular purification board manufacturers.

How to deal with the residual glue on the purification board?

 The purification boards can be combined and installed as needed, which can reduce a lot of costs and facilitate installation. However, due to manual work, many construction workers will get glue on the purification boards during construction, so how to deal with it? FRP lighting tiles

       1. Use bananas to drip water on the glue stains, and at the same time use brushes and other scrubbing tools to continuously stir and scrub. After the glue stain becomes soft and falls off, rinse with clean water and scrub repeatedly until it is clean. Stick an absorbent cloth on the back of the material with glue marks, then apply some white vinegar on the glue marks, and wipe clean with cotton dipped in water.

       2. Acetone solution can be washed (but acetone solution is poisonous, so be careful when using it). 502 glue is a kind of resin glue, as long as you use an organic solvent such as acetone to dissolve the resin. However, inhaled acetone is toxic, so be careful how you use it. You can put a part of the glue in the ultra-low temperature environment, and the glue will fall off. If the purification board is covered with 502 glue on a large area and coated with acetone, it can be removed in about 5 to 10 minutes.

       3. If there are glue stains, you can use acetone or banana to drip some water on the glue stains. Brush repeatedly with a brush. After the glue stain has softened and been removed from the material, rinse with clean water. If it fails once, you can scrub it several times and clean it.

     Roofing Material must have the correct installation and use method throughout the use process. Only by using the correct method can the purification board be able to complete the effect, and the use effect can be well guaranteed. If it is used incorrectly, the product will not be able to perform well, which will affect the installation process.

Where will the purification board be used?

 At present, there are many places that will be rebuilt or rebuilt, and the purification board plays a very important role at this time, so the purification board has also been applied to many aspects. Most of the purification panels are used in some laboratories, or hospital operating rooms, biological tissue culture rooms, etc. The main purpose is to prevent bacterial invasion.

       FRP Panel manufacturers Because many people don't know exactly what the purification panel is used for, so they don't know how to choose the purification panel. Most of the time, it will cause the waste of the board, and it will also cause some safety problems, so we should be very clear about its function when choosing the board.

       Roofing Material suppliers will tell you in detail about the structure, function and other aspects of the board. Its main structure is composed of two layers of color-coated boards and rock wool in the middle. Color-coated boards can prevent static electricity and have corrosion resistance, while rock wool has good insulation and fire protection. They are all materials that are often used in the purification process.

Benefits of FRP lighting panels

 Most of the building materials used in traditional building roofs are color steel tiles, which have many disadvantages. For example, there are many rainy seasons in the south. Excessive water accumulation for a long time will lead to more and more pollution. Over time, the roof will rot and corrode, making the roof larger. renovation of the area.

     Roofing Material manufacturers can completely solve these problems. Rainwater can flow down the tile surface, and the accumulated dirt can also be washed away with the rainwater. At the same time, the advantages of FRP lighting tiles are: good sound insulation effect. The phoneme measurement test shows that when subjected to external noise such as heavy rain, hail, and strong winds, FRP lighting tiles can absorb noise well or reduce the passage of noise. Lightweight and easy to install and transport. Excellent corrosion resistance, even in the environment with acid and alkali, there is no problem at all, and it has a service life of 15-25 years. The light transmittance of FRP lighting tile is about 80%, so that you can bathe in sunlight no matter you are in a high-rise building or an industrial plant.

Will the lighting board be affected by temperature?

 Today Roofing Sheet manufacturers will introduce what kind of influence the temperature will have on the lighting sheet


     In fact, like many materials, the strength of transparent roof sheet will decrease with the increase of temperature. When the temperature rises to a certain value, the strength will drop sharply; the difference between the lighting sheet and other materials is that it will not change at low temperature. Brittle, because the low temperature performance of the lighting board is very good. In addition, the impact strength tends to increase as the temperature decreases, so the lighting board will not age, turn yellow, crack or soften under the temperature of -40°C-95°C. What's more, the lighting board has strong light transmission, and diffuses the light, eliminating the focus and shadow, and the light is soft and uniform. However, the light transmitted by PC and glass is direct, which makes the indoor light uneven, which will lead to a decrease in work efficiency.

     The above is about the influence of temperature on the lighting board. It should be noted that when storing the lighting board, it should be stored in a place that avoids direct sunlight, is moisture-proof, and has good ventilation conditions.
