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，四川康泰CPVC廠家直銷，四川康泰CPVC廠家直銷，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，四川康泰CPVC廠家直銷，作為剛性粒子的填充劑。CPVC管道是新型的塑料管道，具有優(yōu)良的耐腐蝕性能，大面積應(yīng)用于化工、冶煉、化纖、電鍍、電子等行業(yè)中。四川康泰CPVC廠家直銷</p><div

CPVC電力電纜保護(hù)管是以樹脂為母料，加入抗沖劑，穩(wěn)定劑等輔料經(jīng)高速擠出而成的新型埋地式高壓電力電纜保護(hù)管。該產(chǎn)品具有**度、柔韌性好、耐高溫、耐腐蝕、阻燃、絕緣性能良好、無污染、不易老化、質(zhì)輕、施工方便等特點，其各項性能指標(biāo)經(jīng)國家、省檢測、鑒定和認(rèn)證，均已達(dá)到或超過國內(nèi)的同類產(chǎn)品水平。產(chǎn)品性能大優(yōu)于傳統(tǒng)的石棉電纜排管及普通PVC管材，是傳統(tǒng)電力電纜護(hù)套管的理想替代品。較普通的UPVC雙壁波紋管耐熱溫度提高15℃，保持不變形，且具有足夠的強度。 </p><p> CPVC的用途：管材：CPVC主要用于生產(chǎn)板材、棒材、管材輸送熱水及腐蝕性介質(zhì)，在不超過100℃時可以保持足夠的強度，而且在較高的內(nèi)壓下可以長期使用。CPVC的重量是黃銅的1/6，鋼的1/5，且有極低的導(dǎo)熱性，因此，用CPVC制造的管道，重量輕，隔熱性能好，不需保溫。CPVC管可用作工廠的熱污水管，電鍍?nèi)芤汗艿?，熱化學(xué)試劑輸送管，氯堿廠的濕氯氣輸送管道。注塑件：CPVC樹脂可生產(chǎn)供水管的管件，過濾材料，脫水機等，還可以生產(chǎn)電器和電子零件。如電線槽，導(dǎo)體的保護(hù)層，電開關(guān)，保險絲的保護(hù)蓋，電纜的絕緣材料等。從而提高了材料的耐熱性、耐酸、堿、鹽、氧化劑等的腐蝕。</p><div
