What are the shortcomings of PC endurance board？

With the development of society, a variety of building plates have appeared in our lives, and pc endurance plate is one of the more common plates. Endurance plate is a kind of polycarbonate processing, also known as PC solid board. Endurance boards are light in weight, transparent and have many advantages. What are the disadvantages of endurance boards? Here is a look at the shortcomings and advantages of endurance board.

First look at the advantages of endurance board:

(1) Light transmission: The light transmission rate of PC-endurance plate can reach 89%, which can be beautiful with glass. UV coated plate in the sun will not produce yellowing, atomization, poor light transmission, ten years later, light transmission loss is only 10%, PVC loss rate is as high as 15%-20%, glass fiber is 12%-20%.

(2) Anti-impact: the impact strength is 250-300 times that of ordinary glass, 30 times that of acrylic plate of the same thickness, 2-20 times that of tempered glass, and there is no crack with the following two meters of 3kg hammer, and there is the reputation of "non-broken glass" and "ring steel".

(3) Anti-ultraviolet: One side of the PC board is co-extruded with anti-ultraviolet (UV) coating, and the other side has anti-condensation treatment, which integrates anti-ultraviolet, heat insulation and anti-fogging functions. It can block the passage of ultraviolet rays, and is suitable for protecting valuable artworks and exhibits from ultraviolet damage.

(4) Light weight: the proportion is only half of the glass, saving the cost of transportation, unloading, installation and support frame.

(5) Flame retardant: The national standard GB50222-95 confirms that the PC-endurance plate is difficult to burn, that is, B1 level. The burning point of the PC board itself is 580 ° C, and it self-extinguishes after the fire, and does not produce toxic gases when burning, and does not contribute to the spread of the fire.

(6) bendability: It can be installed into arched, semi-circular roof and window according to the design drawing by cold bending method at the site. The minimum bending radius is 175 times the thickness of the plate, and can be hot bent.

(7) sound insulation: the sound insulation effect of the PCB is obvious, and the sound insulation of the PCB is better than that of the glass and the sub-extension plate of the same thickness, and the sound insulation of the PCB is 5-9dB higher than that of the glass under the same thickness conditions. Internationally, it is the preferred material for highway noise barriers.

(8) Energy saving: summer cooling, winter insulation, PC-endurance plate has a lower thermal conductivity (K value) than ordinary glass and other plastics, the thermal insulation effect is 7%-25% higher than the same glass, and the thermal insulation of PC-endurance plate is up to 49%. Thus, the heat loss is greatly reduced, and it is used in buildings with heating equipment, which is an environmentally friendly material.

(9) Temperature adaptability: PC board does not occur cold and brittle at -40 ° C, does not soften at 125 ° C, and has no significant changes in its mechanics and mechanical properties in harsh environments.

(10) Weather resistance: PC-endurance plate can maintain the stability of various physical indicators in the range of -40℃ to 120℃. In the artificial weathering test for 4000 hours, the yellowing degree is 2, and the transmittance decreases by only 0.6%.

(11) Anti-condensation: When the outdoor temperature is 0℃, the indoor temperature is 23℃, and the indoor relative humidity is lower than 80%, the inner surface of the material is not condensation. The dew will run off the surface of the plate without dripping.

(12) Simple and convenient, not as bulky as traditional materials, since its inception has been widely used in various fields.

What are the shortcomings of the endurance board? The shortcomings of the endurance board should be the characteristics of all polycarbonate PC boards, all PC boards are not acid resistant, not alkali resistant, and need to add UV coating on the surface for special purposes. Buy endurance board or sunshine board do not buy inferior, the price of endurance board is relatively high, some manufacturers and dealers from raw materials and thickness up shoddy, so that the endurance board on the market has a lot of inferior products.
