PC耐力板的特點(diǎn)： 透光性：透光性能好（透光率達(dá)88％）。在陽(yáng)光下暴曬不會(huì)產(chǎn)生變黃 霧化 透光不佳。 耐候性：表面有防紫外線的共擠層，可防止太陽(yáng)光紫外線引起的樹(shù)脂疲勞變黃。表面共擠層具有化學(xué)鍵吸收紫外線并轉(zhuǎn)化為可見(jiàn)光。對(duì)植物光合作用有良好穩(wěn)定效果。 抗沖擊：PC耐力板的沖擊強(qiáng)度是普通玻璃的250－300倍，是亞克力板材的20－30倍，是鋼化玻璃的2倍，幾乎沒(méi)有斷裂的危險(xiǎn)性。 阻燃性：據(jù)國(guó)家GB8624-97測(cè)試阻燃B1級(jí)，無(wú)火滴，無(wú)毒氣。 耐溫性：在攝氏－40度C至＋120度C溫度范圍內(nèi)不會(huì)引起變形等品質(zhì)劣化。 輕變性：重量輕，便于搬運(yùn) 鉆孔。截?cái)喟惭b時(shí)，不易斷裂，而且可直接冷彎，施工簡(jiǎn)便加工良好。 隔音性：隔音效果佳，在國(guó)際上是高速公路隔音屏障的首選材料。 Specification of PC sheet Light transmission:excellent light transmission (up to 88% of light transmitted through).when exposed under sunshine .there are no yellow ,hazoring or and poor light transmission caused Weather resistance : the ultraviolet –resistant coextruded film on the surface prevents them from resin fatigue and yellowing caused by ultraviolet of sunshuine .the chemical bond on the coextrude film absorbs the ultraviolet and then it into visible light .it has a stsble effect on plant photosynthesis . Impict resistance :the impact strenghe of PC sheet is 250-300 times of the ordinary glass ,20-30 times of the alkali glass and 2 times of toughened glass which explains why it is hardly broken . Fire retardant :through national GB8624-97 test ,their fire retardant is regarded as grade B without fire drop or poisonousgas Temperature resistance :they will not deformed under temperature from -40duCto 120duC. Portability : it is light which makes it easily handled and drilled .when cut for installation ,they are hardly cracked .besides that ,they can be cold bent directly ,convenient for construction and procession Sound insulation :with good sound insulation effect.it is the best materials for sound –insulation walls on expressways worldwise .
