一、 聲屏障專用PC板的抗化學(xué)性
A sound barriers, special chemical resistance of the PC board
聚碳酸酯在常溫下對(duì)弱酸、弱堿及醇類的抵御功用超卓，但對(duì)強(qiáng)酸堿、苯類、氯化烴類和酯類的抵御功用稍差，很簡(jiǎn)單發(fā)生溶解、溶脹或分化的景象。因?yàn)槠淇够瘜W(xué)性與溫度凹凸、內(nèi)部殘留應(yīng)力巨細(xì)及露出時(shí)刻長(zhǎng)短有關(guān)，故運(yùn)用前應(yīng)特別注意。
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、 聲屏障專用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資料的首選資料，PC耐力板已被廣泛應(yīng)用于高速公路聲屏障、高架橋聲屏障、活絡(luò)路聲屏障、鐵路聲屏障、軌道交通聲屏障、高鐵聲屏障、小區(qū)隔音屏障等聲屏障工程。
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、 聲屏障專用PC板的分量輕
Three special PC board, sound barrier of lightweight
在一樣厚度及面積下，PC耐力板分量?jī)H為玻璃的一半，因而可很多節(jié)約轉(zhuǎn)移及聲屏障施工的難度。
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、聲屏障專用PC板的機(jī)械功用
Four sound barriers, special mechanical functions of the PC board
1、抗沖擊強(qiáng)度：PC耐力板抗沖擊功用極佳，它比傳統(tǒng)玻璃高250倍，比亞克力板材高30倍。Pc耐力板的沖擊強(qiáng)度有如"通明鋼板"之稱。
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、拉伸強(qiáng)度好，PC耐力板耐熱性佳，即便在120℃，其拉伸強(qiáng)度仍可達(dá)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、曲折強(qiáng)度：PC耐力板抗彎性超卓，即便曲折視點(diǎn)達(dá)90°，仍不開裂。
3, folding strength: PC endurance plate bending excellence sex, even if the twists and turns a viewpoint of 90 °, still no crack.
4、抗疲勞與抗蠕變性：PC耐力板抗蠕變性在熱塑性塑膠中是最佳的。即便在高溫下其蠕變?nèi)院苄 ?br/>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、 聲屏障專用PC板的光學(xué)功用
Five, the optical functions of noise barrier special PC board
1、透光率：PC耐力板的透光率為85%至90%之間與玻璃恰當(dāng)。
1, light transmittance: PC endurance plate between the light transmittance of 85% to 90% with the glass.
2、耐候性：通常PC耐力板材長(zhǎng)時(shí)間露出室外，受紫外線照耀易致使黃變及表層劣化。高鋒PC耐力板外表附有一層抗UV層，即便長(zhǎng)時(shí)間露出室外，其光學(xué)，機(jī)械功用均無(wú)明顯改動(dòng)。
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、聲屏障專用PC板的熱功用
Six sound barriers, special PC board heat function
1、熔形溫度：PC耐力板熔形溫度135℃，其接連運(yùn)用溫度達(dá)120℃。
1, melting temperature: PC endurance plate melt temperature 135 ℃, its continued use temperature of 120 ℃.
2、線膨脹系數(shù)：線膨脹系數(shù)為7×10-5cm/cm/℃在塑膠中屬較小的。
2, linear expansion coefficient, linear expansion coefficient of 7 x 10-5 cm/cm / ℃ is smaller in the plastic.
3、脆化溫度：PC耐力板脆化溫度為-40℃，最低接連運(yùn)用溫度為-30℃，是通常塑膠不可比的。
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、燃燒性：PC耐力板屬難燃自熄性塑膠之一，其在高溫加熱時(shí)不會(huì)發(fā)生有毒氣體。
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、熱傳導(dǎo)率：PC耐力板的熱導(dǎo)率與通常塑膠區(qū)別不大，是玻璃的1/4，鐵的1/300，鋁的1/1000，銅的1/2000，屬保溫功用優(yōu)秀的資料之一。
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.
