首先說下PPR管材加工過程，這中間的諸多因素對管材的質(zhì)量至關(guān)重要。例如：原料選擇、溫度、螺桿轉(zhuǎn)速、壓縮空氣、牽引速度、牽引冷卻等等都會對PPR管材造成影響。1、原料的選擇是最基本的也是道因素：PPR原材料的規(guī)格牌號種類繁多，數(shù)不勝數(shù)，同樣一種牌號的原材料可以生產(chǎn)PPR波紋管但卻不能山產(chǎn)PPR給水管。在這里還是需要廠家自己去多多試驗，選擇適合自已生產(chǎn)管材的料。2、溫度對PPR管材質(zhì)量的影響：溫度是影響塑化及塑料管材生產(chǎn)的主要因索，溫度過低，塑化不好，溫度過高，物料易分解。溫度的控制應(yīng)根據(jù)原配方、擠出機(jī)及機(jī)頭結(jié)構(gòu)、螺桿轉(zhuǎn)速等因素確定。加工硬pvc管材時，因加工溫度與分解溫度頗為接近，生產(chǎn)中應(yīng)嚴(yán)格控制各點的料溫。同時注意測溫儀表的誤差及測量點的位置。3、螺桿轉(zhuǎn)速對管材質(zhì)量的影響：螺桿轉(zhuǎn)速的選擇直接影響產(chǎn)量和質(zhì)量。螺桿轉(zhuǎn)速既取決于擠出機(jī)大小，一邊取決上管徑大小。轉(zhuǎn)速增加，擠出量增加，物料受到的剪切力大，有助于物料的塑化，但是物料在螺桿內(nèi)的停留時間較短，過高的摩擦熱使管內(nèi)壁比較粗糙、管材強(qiáng)度下降，因此，螺桿轉(zhuǎn)速的控制應(yīng)根據(jù)產(chǎn)量、產(chǎn)品外觀和物理力學(xué)性能要求權(quán)衡。
