Why anti-fogging polycarbonate is popular for conservatory?The reason why polycarbonate agricultural anti-fogging polycarbonate sheets can be used in a large number of conservatory covering materials is that it has high-quality light transmission, aging resistance, impact resistance, light weight, easy processing, good heat preservation and other properties. It has better performance than any lighting material in the world at present-(anti-fogging effect), whether it is glass or film greenhouse, it is inferior. What is polycarbonate sheet with anti-fogging technology ?Polycarbonate sheet with anti-fogging is useful for greenhouse.The temperature difference between indoor and outdoor will cause water vapor to condense on the walls and ceilings in the greenhouse, forming small fog droplets, reducing the light transmittance, due to further condensation, they will drip down and harm plants, use Plant green leaves turn yellow, anti-fog drop. In addition to all the excellent performance of ordinary twinwall polycarbonate , this polycarbonate can also prevent fog drop. The inclined surface (in the direction of the ribs of the plate) slides to the edge instead of directly dripping, so as to achieve the effect of anti-fog drop, reduce the crop diseases in the room, improve the light transmission performance, etc., all have significant advantages and are greatly welcomed by growers Therefore, it has become the first choice for the construction of new greenhouses and the replacement of light-transmitting covering materials for old greenhouses, and is widely used in greenhouse projects. How to distinguish the quality of anti-fogging polycarbonate? However, the quality of this agricultural anti-fogging polycarbonate is mixed, and the fish eyes are mixed, which increases the difficulty for users to identify the authenticity. The anti-fog does not have a grower and also causes huge joint economic losses, which triggers various legal proceedings. The number of cases is also increasing. How to distinguish the quality of anti-fogging polycarbonate? Choosing cost-effective products has become a problem that everyone must consider. At present, most of the friends in the greenhouse circle choose to introduce friends and some older brands. They would rather spend more money than buy a product that you can use with confidence. I also use this idea. Generally, I pay less attention to the effect of anti-fog drop. As long as it is an anti-fog drop polycarbonate sheet, ten-year quality assurance is enough, but what are the advantages of such big brands as GE? Why is it more expensive than domestic ones? It is because the anti-fog dripping boards produced by some small domestic factories are coated with silica gel and washing powder, and the effect is completely gone in about a year, including some PC board companies that are relatively influential in the greenhouse. The anti-fog dripping oil they imported is all added with distilled water, the ratio of 1:1, the effect can be imagined. And brands such as GE, Bayer, Jaspo and other brands use co-extrusion technology to squeeze into the surface of the sheet during production, and it has already formed an integral body with the sheet, and its effect will not be used for 10 years or more. There is a qualitative problem. How to identify the anti-fog drop effect? How to identify the anti-fog drop effect? According to the agricultural industry standard of the Ministry of Agriculture of China, TSO8296-1987, GB/T14216-1993, plastic wetting tension test method: ASTMD5725-95, test method, this test is judged from surface tension and contact angle. The most intuitive and simple test method is the stop drop area judgment method, the beaker test method, and the fog drop time test method.Now introduce the beaker test method, how to compare the anti-fog drop PC board, the anti-fog effect is good or bad, prepare 2 beakers, 2 anti-fog boards from different companies, fill the 2 beakers with 90% boiling water, and then The anti-fog drip board of different companies has the anti-fog side, put it on the beaker, pay attention to the change of the plate fog, the anti-fog effect of the product is good and bad, it is obvious, don't know, you can see the result. (Result: The smaller the condensation time and the coverage area, the better, or the shorter the time for the condensation droplets to fall, the better the anti-fog drop performance, the faster the sheet fogging time, the worse the anti-fog effect)
what's a curtain wallA curtain wall is the building's exterior wall enclosure, does not bear the weight, is a modern large and high-rise buildings commonly used with decorative effect of the lightweight wall. It is now mid-to-late August, and autumn has entered, and some large shopping malls and office buildings will soon face the problem of heating in winter. The contrast between two different materialsNowadays, most buildings use glass curtain walls. Although glass curtain walls are very popular, they have a natural disadvantage in heating compared with building curtain walls made of Polycarbonate.The heat transfer coefficient of glass is relatively high. If glass curtain walls are adopted, a large amount of indoor heat is easily lost in the building. In this case, it may consume more energy and spend more money on heating, which undoubtedly increases operating costs. However, a Polycarbonate sheet has a natural advantage for heating.The polycarbonate curtain wall has a low heat transfer coefficient (K value), only 1.1-4.1W/m2℃, and its thermal insulation performance is 7 to 25% higher than that of a glass of the same thickness. The lower heat transfer coefficient of the Polycarbonate sheet can reduce the transmission of indoor and outdoor temperature, so as to achieve good indoor heat preservation and reduce energy consumption. It can be said that it achieves the dual purpose of heat preservation and energy saving and environmental protection at the same time.Other advantages of PC hollow sheet curtain wall■Hilproof and windproofLarge shopping malls, office buildings, and other places have a large flow of people, and buildings have the mission of ensuring public safety and resisting natural disasters. Polycarbonate hollow sheet has super impact resistance, which is 250 times that of a glass of the same thickness, 30 times that of plexiglass, and 20 times that of tempered glass. It can resist hail, typhoons, man-made collisions, and other accidental damage to the building. A multiwall polycarbonate sheet is undoubtedly a curtain wall material that can ensure the safety of personnel better than glass.■ Flame retardant and fireproofThe flame-retardant grade of multiwall polycarbonate sheet is flame-retardant grade B. Its ignition point is as high as 580℃. It has the characteristics of self-extinguishing after leaving the fire. At the same time, it will not produce toxic gases when it burns, and it will not contribute to the spread of fire. This level of fire performance is more suitable for crowded places such as shopping malls and office buildings and meets the safety requirements of public places.■ Adequate daylighting to save energyThe PC hollow sheet has strong light transmittance, a large amount of sunlight comes in, which can reduce the use of lights in office buildings, shopping malls, and other places, and achieve the purpose of saving energy. The light transmittance of a multiwall polycarbonate sheet is 23-80%, and its light transmittance can be adjusted according to the actual application and color of the board. Generally speaking, using multiwall polycarbonate sheet as the exterior wall of the building can not only ensure a beautiful appearance, but also ensure an excellent Office and shopping experience.■ Various colors and strong fashionNowadays, most office buildings and shopping malls have very unique designs, and the color of the PC hollow sheet can be customized to meet the colors required by any design scheme. Undoubtedly, the characteristics of PC panels are more favored by builders.■Cost-effectivePC sheet has the above advantages, but multiwall polycarbonate sheet price is far lower than that of glass, and its installation and maintenance cost is also much lower than that of glass. It is a cost-effective building material.
Polycarbonate sheet is rigid-structure with a least two walls and
connective ribbing. Multiwall polycarbonate sheet is ideal glazing
material especially for building cladding .Building
cladding is the exterior skin of architect. The clapping serve both a
decorative and a functional purpose.Usually building cladding offers
protection from rain, snow and impact. Multiwall polycarbonate sheet is
real unbreakable. 250 times stronger than traditional glass. While
multiwall polycarbonate sheet is lightweight, half weight of glass.
These feature make multiwall polycarbonate sheet superior material for
building cladding. Multiwall Polycarbonate sheet is made by high temperature and high pressure gluing and pressing, so multiwall polycarbonate sheet is
not easy to crack and deform, and the shrinkage expansion coefficient
is small. It can better regulate the indoor temperature and humidity,
and it is a breathing sheet. Multiwall
polycarbonate sheet creates insulating air spaces that helps reduce
thermal energy penetration. A cooler area in summer and a warmer area in
winter. Substantially a better energy efficient than any single-layer
addition, it has better water resistance and is more resistant to
moisture than ordinary solid wood. The multi-layer polycarbonate board
has strong compressive resistance, and its load-bearing capacity is
stronger than that of a single-layer polycarbonate board. But the weight
is much lighter, easy to move and easy to install. Besides,
multiwall polycarbonate sheet has a superior day lighting advantage.
After the sunlight is filtered through the polycarbonate sheet, the
light becomes soft, unlike the direct sunlight of the glass. Realize the
unity of architectural optics and aesthetics. Make the whole building
cladding transparent and warm.
