而有很大的差異，有時(shí)這種差異會(huì)有20～30℃。理論上，CPVC材料的加工溫度要比PVC高，但實(shí)際上，根據(jù)我們多年的加工經(jīng)驗(yàn)，CPVC的加工溫度要比PVC低5～8℃，這是因?yàn)镃PVC熔融粘度比PVC大，熔融的分子之間將會(huì)產(chǎn)生大量的摩擦熱，這時(shí)如果擠出機(jī)再提供給它過(guò)多的熱量，很容易造成物料的分解，四川日豐CPVC一級(jí)經(jīng)銷商。在工藝溫度設(shè)定上，應(yīng)盡量保持曲線的平緩，這樣有利于CPVC樹(shù)脂的塑化質(zhì)量，曲線忽上忽下不利于管材的塑化，四川日豐CPVC一級(jí)經(jīng)銷商，四川日豐CPVC一級(jí)經(jīng)銷商，一般曲線為“U”形是比較適宜的。整個(gè)工藝溫度的控制大體可以分為三部分：機(jī)筒、合流芯和模具，機(jī)筒溫度從一區(qū)開(kāi)始依次遞減，合流芯溫度又要比機(jī)筒溫度略低一些，在模具的溫度設(shè)定中，值得注意的是口模的溫度和芯模的溫度，口模的溫度應(yīng)比機(jī)筒的加熱段溫度低10℃左右，否則會(huì)影響管材的縱向回縮率，對(duì)縱向回縮率無(wú)要求的管材則不受此限制，芯模加熱可以在管材正常牽出后即斷開(kāi)，CPVC熔體的熱量和對(duì)芯模摩擦所產(chǎn)生的熱量完全可以維持芯模的溫度。CPVC

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。氯化bai聚氯乙du烯zhi（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dao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。基本性能與PVC相仿，但PVC樹(shù)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明顯改善，是一種質(zhì)優(yōu)價(jià)廉的工程塑料。

CPVC管道系統(tǒng)具有耐腐蝕、耐沖擊、不易變形、內(nèi)壁光滑、不易結(jié)垢、保溫性好、不導(dǎo)電、粘接方便、使用壽命長(zhǎng)等特性。因此在性價(jià)比高與施工費(fèi)用低廉的優(yōu)勢(shì)上逐漸取代其它金屬管道系統(tǒng)，而且CPVC管道系統(tǒng)維修保養(yǎng)方便快速，無(wú)需長(zhǎng)時(shí)間停機(jī)而造成巨大損失，故CPVC管道系統(tǒng)是當(dāng)前工業(yè)管道設(shè)計(jì)的優(yōu)先。CPVC管道系統(tǒng)所允許比較高使用溫度為110℃，長(zhǎng)期使用溫度為95℃。其適用于在標(biāo)準(zhǔn)允許的壓力范圍內(nèi)輸送熱水及腐蝕性介質(zhì)。一般用于石油、化工、電子、電力、冶金、造紙、食品飲料、醫(yī)藥、電鍍等工業(yè)領(lǐng)域。CPVC材料由于國(guó)內(nèi)PVC粒子表皮較厚，除膜技術(shù)不足，所以氯化時(shí)不易均勻氯化，表氯含量高。加之聚合時(shí)的斷鏈較多等因素，所以CPVC制品加工過(guò)程容易分解。阻燃性能：具有良好的阻燃性能，能離火即熄。</p><div

對(duì)于氯化聚氯乙烯（CPVC）大家可能不是那么的熟悉，其實(shí)就是一種通過(guò)聚氯乙烯然后進(jìn)一步改性的產(chǎn)品，改性之后除了兼有聚氯乙烯的一些優(yōu)良性能之外，還在其它性能上有了一定的提高，進(jìn)而使產(chǎn)品在很多的領(lǐng)域中大面積的應(yīng)用著，為了更好的了解產(chǎn)品，讓我們一起來(lái)看一下產(chǎn)品的改性方法都有哪些吧。增韌改性；為改善氯化聚氯乙烯（CPVC）的脆性，常加入ACR、CPE、ABS、MABS、MBS、POE等增韌劑；添加量一般為4~10份。填充改性；CPVC常用的填充劑為無(wú)限填料，主要有碳酸鈣、鈦白粉、二氧化硅、氧化鋁、煅燒陶土、玻璃纖維等；由于CPVC自身的沖擊強(qiáng)度差，填料的添加量應(yīng)控制在20份以下，并需要進(jìn)行表面處理。增強(qiáng)改性；在氯化聚氯乙烯（CPVC）中加入玻璃纖維可以提高其熱變形溫度和沖擊強(qiáng)度，加20份玻纖可將沖擊強(qiáng)度提高10倍。耐熱改性；在CPVC中加入鈣鎂氫氧化物、亞甲基或亞乙基雙硬脂酰胺類的穩(wěn)定劑，可以提高其熱變形溫度（亞甲基或亞乙基雙硬脂酰胺可以使CPVC的熱變形溫度提高10~15℃）。絕緣性能：C-PVC電力管能經(jīng)受3萬(wàn)伏以上的高壓。成都日豐CPVC代理商</p><p
