Basically reformed the greenhouse condition. Prospects for development
The application of the sunshine board Just beginning, in the construction of the modern agriculture greenhouse. Important in Beijing and the northern cities. Greenhouse construction, there is the greenhouse of all use sunshine board building, built of greenhouse with gable use sunshine board, also have a gable wall and side wall application greenhouse in sunshine board construction. Greenhouse effect, there are mainly production of production-oriented greenhouse, there are mainly flowers trading center trading greenhouse, and mainly research the greenhouse. The greenhouse partial or all use sunshine board as cloud data, make the ecological environment of greenhouse has been further improved.
Every year 20% of 50 million square meters of the sunshine board market for agriculture greenhouse; North America, Europe. Every year 70% of 60 million square meters sunshine board market for agriculture greenhouse. China is a agricultural country, and large population, limited land resources, the development in agriculture, agricultural greenhouse factory and efficiently construction is the basic future agricultural development, and the sunshine board as the fourth generation of the construction of agricultural greenhouse cover material will has a very extensive use. M type sunshine board is widely used in curtain wall. PC cellular sunshine board product features
(1) the transmission of light: P C sunshine board light transmittance as high as 89%, equivalent to that of glass Bi beauty. UV coating plate blasting bask in the sun won't produce yellowing, atomization, pervious to light, the transmission loss is only 10%, after ten years of PVC turnover rate is as high as 15%, 20%, glass fiber was 12% - 20%.
(2) the impact resistance, impact strength is common glass of 250-300 times, 30 times that of the same thickness of acrylic, 2-20 times that of toughened glass, the following two meters with 3 kg hammer drop no crack, there are "no broken glass" and the "ring of steel" laudatory name.
(3) the UV protection: PC board side co-extrusion have resistance to ultraviolet (UV) coating, on the other side has the condensation process, anti-ultraviolet radiation, insulation against the droplets functions in one. Can block ultraviolet light through, and is suitable for protecting valuable works of art and exhibits, make it from uv damage.
(4) light weight: the weight is only half of the glass, save transportation, unloading, installation and support framework cost.
(5) flame retardant: national standard GB50222-95 confirmed that P C sunshine board difficulty level, namely the B1 level. Ignition point is 580 ℃, PC board itself from the self-extinguishing fire, burning will not produce poisonous gas, don't feed the fire from spreading.
(6) can be bending: in accordance with the design adopts cold bending method, at the site installation arched, semicircular roof and Windows. Minimum bending radius of the plate thickness of 175 times, hot bending.
(7) sound insulation sex: P C sunshine board sound insulation effect is obvious, than the same thickness and the strength of glass plate have better sound insulation, the thickness under the same conditions, the sound insulation quantity of P C sunshine board 5 -- 9 db higher than that of glass. In the world is the first selection of highway noise barrier material.

Cellular sunshine board screw installation method
(1) screw spacing, can according to the thickness, make the appropriate configuration, spacing is too small and too much is not good. Such as the spacing is too small, sometimes stress caused by too tight, cause damage; Such as spacing is too big, and can make the PC board fixed instability. Therefore the spacing is recommended for the:
A: thickness below 3.0 mm, spacing of 10 ~ 20 cm
B: thickness below 3.0 mm, spacing of 20 ~ 30 cm
C: if the layering is fixed, the distance of 20 ~ 30 cm
Note: such as PC board, fixed directly with self tapping screw, the screw spacing, the greater the plate is not easy to damage due to stress.
(2) the size of the screw holes PC board must be considered summer night heat bilges cold shrink and book. In general, the screw holes should be larger than the screw diameter at least 2 ~ 4 mm, to reserve expansion space
(3) the position of the screw holes from the edge of the PC board is too close, very easy to cause the broken plate, in general, the position of the screw holes from the PC board edge is more than 2.5 times the diameter of the screw holes. For example, the diameter of 4 mm screw, the screw holes position at least to have more than 1 cm away from the PC board edge.
(4) screws do not lock is too tight, otherwise the deformation, and stress.
(5) lock the screw on the PC analysis had better not choose self tapping screw, otherwise produce stress, and stress at the plate thickness increases.
(6) to reduce the pressure of screw with material directly, and the available gaskets pad during filling, but PVC washer and some rubber ring will destroy the PC board, do not use. Recommend the use of the gasket material for epdm like rubber, silicone rubber and neoprene
