一、 声屏障专用PC板的抗化学性   
A sound barriers, special chemical resistance of the PC board


聚碳酸酯在常温下对弱酸、弱碱及醇类的抵御功用超卓,但对强酸碱、苯类、氯化烃类和酯类的抵御功用稍差,很简单发生溶解、溶胀或分化的景象。因为其抗化学性与温度凹凸、内部残留应力巨细及露出时刻长短有关,故运用前应特别注意。
Polycarbonate at room temperature to weak acid, weak alkali and alcohol resistant function have excellence, but in strong acid and alkali, benzene, chlorinated hydrocarbons and esters against function is a bit poor, easy to dissolve, swelling or differentiation. Because of its chemical resistance and temperature is concave and convex, internal residual stress tests, and show the time length, so should pay special attention to before use.
 
二、 声屏障专用PC板的隔音功用  
Second, the special PC board sound insulation noise barrier function
PC板的隔音作用比玻璃高3-4DB,隔音屏障的通明隔音资料的首选资料,PC耐力板已被广泛应用于高速公路声屏障、高架桥声屏障、活络路声屏障、铁路声屏障、轨道交通声屏障、高铁声屏障、小区隔音屏障等声屏障工程。
PC board sound insulation effect is higher than glass 3-4 db, noise barriers hyaline material of choice for sound insulation materials, PC endurance plate has been widely used in highway sound barrier, sound barriers viaduct, adjustable road noise barrier, railway, rail traffic noise barrier, noise barrier Gao Tiesheng barrier, such as community noise barrier engineering noise barrier.
三、 声屏障专用PC板的分量轻   
Three special PC board, sound barrier of lightweight
在一样厚度及面积下,PC耐力板分量仅为玻璃的一半,因而可很多节约转移及声屏障施工的难度。
Under the same thickness and area of PC endurance plate component is only half of the glass, so can save a lot of transfer and the difficulty of the construction noise barrier.
四、声屏障专用PC板的机械功用  
Four sound barriers, special mechanical functions of the PC board
1、抗冲击强度:PC耐力板抗冲击功用极佳,它比传统玻璃高250倍,比亚克力板材高30倍。Pc耐力板的冲击强度有如"通明钢板"之称。   
1, impact strength, excellent PC endurance plate shock function, it is 250 times higher than the traditional glass, 30 times higher than acrylic. The impact strength of Pc endurance plate as "bright steel".
2、拉伸强度好,PC耐力板耐热性佳,即便在120℃,其拉伸强度仍可达350kgf/cm2。  
2, good tensile strength, PC endurance plate heat resistance, even at 120 ℃, its tensile strength is still up to 350 KGF/cm2.
3、曲折强度:PC耐力板抗弯性超卓,即便曲折视点达90°,仍不开裂。
3, folding strength: PC endurance plate bending excellence sex, even if the twists and turns a viewpoint of 90 °, still no crack.
4、抗疲劳与抗蠕变性:PC耐力板抗蠕变性在热塑性塑胶中是最佳的。即便在高温下其蠕变仍很小。
4, fatigue and creep resistance: PC endurance plate creep resistance is the best in the thermoplastic plastic. Even if its creep at high temperature is still very small.
五、 声屏障专用PC板的光学功用   
Five, the optical functions of noise barrier special PC board
1、透光率:PC耐力板的透光率为85%至90%之间与玻璃恰当。   
1, light transmittance: PC endurance plate between the light transmittance of 85% to 90% with the glass.
2、耐候性:通常PC耐力板材长时间露出室外,受紫外线照耀易致使黄变及表层劣化。高锋PC耐力板外表附有一层抗UV层,即便长时间露出室外,其光学,机械功用均无明显改动。
2, weatherability, PC endurance plate exposed outdoor for long, usually by ultraviolet light shine is easy to cause yellowing and surface degradation. Irreverent comedy PC endurance plate appearance with a layer of UV resistant layer, even if long time outdoor, its optical and mechanical function had no obvious changes.
六、声屏障专用PC板的热功用   
Six sound barriers, special PC board heat function
1、熔形温度:PC耐力板熔形温度135℃,其接连运用温度达120℃。  
1, melting temperature: PC endurance plate melt temperature 135 ℃, its continued use temperature of 120 ℃.
2、线膨胀系数:线膨胀系数为7×10-5cm/cm/℃在塑胶中属较小的。   
2, linear expansion coefficient, linear expansion coefficient of 7 x 10-5 cm/cm / ℃ is smaller in the plastic.
3、脆化温度:PC耐力板脆化温度为-40℃,最低接连运用温度为-30℃,是通常塑胶不可比的。   
3, brittle temperature: PC endurance plate brittle temperature was minus 40 ℃, the lowest in succession the use of temperature of 30 ℃, are usually not than plastic.
4、燃烧性:PC耐力板属难燃自熄性塑胶之一,其在高温加热时不会发生有毒气体。   
4, combustibility: PC endurance plate belongs to one of flame retardant self-extinguishing plastics, its in the high temperature heating of poisonous gas will not occur.
5、热传导率:PC耐力板的热导率与通常塑胶区别不大,是玻璃的1/4,铁的1/300,铝的1/1000,铜的1/2000,属保温功用优秀的资料之一。
5, thermal conductivity: PC endurance plate thermal conductivity and plastic difference is not big, often is about a quarter of the glass, 1/300 of the iron, aluminum, 1/1000 of 1/2000 of the copper, it is one of heat preservation function good information.
