3、抗沖改性劑和加工助劑由于CPVC樹脂氯含量較高，它的抗沖擊性能比PVC樹脂更差，必須加入抗沖擊劑加以改性，常用的抗沖擊劑有：CPE、MBS、ABS和抗沖型ACR等，在CPVC管材的加工中加入CPE，其增韌效果十分明顯，添加量在8～12份之間增韌效果**好，但加入CPE會明顯降低管材的維卡軟化溫度;MBS、ABS對維卡軟化溫度影響較小，但由于它們的分子鏈中含有不飽和雙鍵，耐候性較差;抗沖型ACR是較為理想的抗沖擊改性劑，但價格較高。綜合上述原因，筆者推薦使用CPE/MBS的混合體作為抗沖擊改性劑，可以兼顧產(chǎn)品對維卡軟化溫度、抗沖擊性、耐候性及價格等諸方面的要求，二者的配比以：1為宜。目前國內(nèi)使用的加工助劑主要為ACR,它是幾種丙烯酸酯類化合物混合在一起的產(chǎn)物，它可以提高樹脂的塑化程度，但CPVC樹脂由于熔融粘度較大，分子之間不需要再借助其他助劑來增加摩擦熱，它比PVC樹脂更容易塑化，因此在擠出加工CPVC管材時應(yīng)少加或不加ACR類促凝劑。4、其他添加劑其他添加劑包括填充劑和著色劑。加入適量的填充劑不僅可以降低成本，還可以改善加工性能。它可以降低CPVC樹脂的加工粘度、改善混料分散性、減少擠出加工時對設(shè)備和模具的粘附性，同時，作為剛性粒子的填充劑。成都多聯(lián)CPVC定制因此，用 CPVC 制造的管道，重量輕，隔熱性能好，不需保溫。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川日豐CPVC定制廠家,CPVC"

CPVC管材是由氯化聚氯乙烯加工而得到的一種耐熱性好的塑料管材。氯化聚氯乙烯(CPVC)是聚氯乙烯(PVC)進(jìn)一步氯化改性的產(chǎn)品，其氯含量一般為65%~72%(體積分?jǐn)?shù))，是一種新型工程塑料。CPVC除了兼有PVC的很多優(yōu)良性能外，其所具有的耐腐蝕性、耐熱性、阻燃性、機(jī)械強(qiáng)度等均比PVC有較大的提高，應(yīng)用前景十分廣闊。CPVC管道性能特點；使用溫度范圍廣：﹣40℃—95℃。具有優(yōu)良的強(qiáng)度和韌性。具有優(yōu)良的耐化學(xué)腐蝕性能。阻燃性能為自熄性。低熱傳導(dǎo)性能，約為鋼材的1/200。介質(zhì)中重離子含量達(dá)超純水標(biāo)準(zhǔn)。衛(wèi)生性能符合國家衛(wèi)生標(biāo)準(zhǔn)要求。重量輕，相當(dāng)于鋼管1/5，銅管的1/6。管壁平潔光滑，輸送流體時具有較小的摩擦阻力和附著力。安裝方便，可采用粘接、螺紋等方式連接，而簡便的是膠水連接。優(yōu)異的耐老化和抗紫外線性能，使正常使用壽命比其他管道系統(tǒng)均有很大的延長。 </p><p> 而有很大的差異，有時這種差異會有20～30℃。理論上，CPVC材料的加工溫度要比PVC高，但實際上，根據(jù)我們多年的加工經(jīng)驗，CPVC的加工溫度要比PVC低5～8℃，這是因為CPVC熔融粘度比PVC大，熔融的分子之間將會產(chǎn)生大量的摩擦熱，這時如果擠出機(jī)再提供給它過多的熱量，很容易造成物料的分解。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樹脂的塑化質(zhì)量，曲線忽上忽下不利于管材的塑化，一般曲線為“U”形是比較適宜的。整個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，否則會影響管材的縱向回縮率，對縱向回縮率無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，CPVC熔體的熱量和對芯模摩擦所產(chǎn)生的熱量完全可以維持芯模的溫度。較普通的UPVC雙壁波紋管耐熱溫度提高15℃，保持不變形，且具有足夠的強(qiáng)度。</p><div

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、使用壽命長等特性。因此在性價比高與施工費(fèi)用低廉的優(yōu)勢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，無需長時間停機(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)計的優(yōu)先。CPVC管道系統(tǒng)所允許比較高使用溫度為110℃，長期使用溫度為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材料由于國內(nèi)PVC粒子表皮較厚，除膜技術(shù)不足，所以氯化時不易均勻氯化，表氯含量高。加之聚合時的斷鏈較多等因素，所以CPVC制品加工過程容易分解。在不超過 100 ℃時可以保持足夠的強(qiáng)度，而且在較高的內(nèi)壓下可以長期使用。成都多聯(lián)CPVC定制</p><p style="text-indent:25px">該產(chǎn)品為白色或淡黃色無味、無臭、無污染的疏松顆粒或粉末。四川日豐CPVC定制廠家</p><p>
