氯化聚氯乙烯（CPVC）
產(chǎn)品說(shuō)明：
氯化聚氯乙烯（CPVC）又名過(guò)氯乙烯，是由特定牌號(hào)的聚氯乙烯（PVC）與氯氣在引發(fā)作用下進(jìn)行取代反應(yīng)而制得的一種新型合成高分子材料，是一種白色或微黃色可流動(dòng)固體粉末�；拘阅芘cPVC相仿，但PVC樹脂經(jīng)氯化改性后制得的CPVC，其耐熱性能、物理機(jī)械性能、化學(xué)穩(wěn)定性能及阻燃性等獲得顯著改善，是一種質(zhì)優(yōu)價(jià)廉的工程塑料。
氯化聚氯乙烯（CPVC）具有良好的耐熱性、耐化學(xué)腐蝕性、防老化性能、阻燃性和熱變形溫度較高等優(yōu)點(diǎn)，既具有PVC的很多優(yōu)良性能，又有良好的阻燃性和低發(fā)煙特性，能耐大多數(shù)的酸、堿、鹽，而且耐熱方面明顯優(yōu)于其它塑料（比普通PVC能提高20－40℃），其維卡耐熱溫度優(yōu)于其它熱塑性塑料。該產(chǎn)品隨著氯含量的提高，其熱變形溫度明顯上升，其機(jī)械強(qiáng)度指標(biāo)也相應(yīng)提高，其應(yīng)用范圍十分廣泛。
氯化聚氯乙烯可取代傳統(tǒng)的熱塑性工程塑料，廣泛應(yīng)用于石油、化工、建材、造船、電器、印染、電鍍、食品及造紙等領(lǐng)域，主要用于制造耐熱、耐腐蝕的管道和配件、住宅管（熱水管道）系統(tǒng)、通信管道系統(tǒng)、排污管道系統(tǒng)等。同時(shí)，根據(jù)氯化程度的不同，CPVC還可用于氯化纖維的改性、制造復(fù)合材料、發(fā)泡材料、涂料及粘合劑等。另外，CPVC還可用作塑料的改性劑，與熱塑性或熱固性塑料摻合共混制造合金，改善材料的性能，使之成為更優(yōu)越的工程塑料。
Chlorinated polyvinyl chloride (CPVC), also known as a vinyl chloride, polyvinyl chloride by specific grades (PVC) and under the effect of chlorine substituted in the trigger reaction obtained a new synthetic polymer materials, is a white or slightly yellow powder can flow. Similar to the basic performance and PVC, but the modified PVC resin obtained by chlorination of CPVC, its heat resistance, mechanical properties, chemical stability and flame retardant, etc. to obtain significant improvement is a cheap project plastic.
Chlorinated polyvinyl chloride (CPVC) has excellent heat resistance, chemical resistance, anti-aging properties, flame resistance and high heat distortion temperature, etc., not only has many excellent performance PVC, and good flame resistance and low smoke properties, the ability of most of the acid, alkali, salt, and heat are significantly better than other plastics (PVC can increase than the average 20-40 ℃), the Vicat heat resistance is superior to other thermoplastics. As the chlorine content of the product increased, the heat distortion temperature increased significantly, its targets have been increased mechanical strength, its wide range of applications.
Chlorinated polyvinyl chloride can replace traditional thermoplastic engineering plastic, widely used in petroleum, chemical, building materials, shipbuilding, electronics, printing and dyeing, electroplating, food and paper and other fields, mainly for the manufacture of heat resistance, corrosion of pipes and fittings , residential pipe (water pipe) systems, communications pipeline system, sewage piping systems. Meanwhile, according to the different levels of chloride, CPVC chlorinated fiber modification can be used to create composite materials, foam materials, coatings and adhesives. In addition, CPVC also be used as plastic modifiers, blending with the thermoplastic or thermoset plastic blend manufacture of alloys, to improve the material properties, making it superior engineering plastics.
