登錄號:9003-07-0，是由丙烯聚合而制得的一種熱塑性樹脂。按甲基排列位置分為等規(guī)pp塑膠原料(isotactic polypropylene)、無規(guī)pp塑膠原料(atactic polypropylene)和間規(guī)pp塑膠原料(syndiotactic polypropylene)三種。</p><p

style="text-indent:25px">模具溫度:40~80℃，建議使用50℃。醫(yī)療高透明pp塑膠原料源頭好貨</p><p style="text-indent:25px">pp塑膠原料加工絕大部份都是靠螺桿帶動流動性，所以螺桿的設(shè)計影響非常大，口徑大小影響產(chǎn)出量，壓縮比大小影響壓力值也影響產(chǎn)出量及成品效果，這也包括多種材料(色母、添加劑及改質(zhì)劑) 的混煉效果。原料流動主要靠加溫器，但原料翻動磨擦也會產(chǎn)生磨擦熱能促使流動性加快，所以螺桿壓縮比小帶動流動小，轉(zhuǎn)速必須加大所造成磨擦熱能必較壓縮比大的螺桿多。所以常說塑料加工無師傅，用心了解機器性能的人就是師傅。原料受熱不只是加溫器而已，必須連摩擦熱及窒留時間都并算在內(nèi)。所以這是實務(wù)問題，經(jīng)驗有助于生產(chǎn)問題解決及效率。螺桿如果需要混煉效果特別好，有時會設(shè)計二段式不同螺桿或雙軸螺桿并分設(shè)各段不同形式螺桿以達各式混煉效果。醫(yī)療高透明pp塑膠原料源頭好貨</p></p><br
