style="text-indent:25px">增強(qiáng)改性pp塑膠原料，纖維狀材料加入到塑料中，可以明顯提高塑料材料的強(qiáng)度，故稱之為增強(qiáng)改性。大徑厚比的材料可以明顯提高塑料材料的彎曲模量(剛性)，也可以將其稱之為增強(qiáng)改性。玻璃纖維是主要的增強(qiáng)材料，可以明顯提高pp塑膠原料塑料的拉伸強(qiáng)度。玻纖含量一般不超過40%，一般認(rèn)為在纖維長度大于0.2mm時有改性效果，其玻纖的直徑在十幾個微米時效果較好。玻纖含量增大時，增強(qiáng)pp塑膠原料的加工流動性相應(yīng)下降，但仍屬流動性較好的塑料。由于玻纖增強(qiáng)pp塑膠原料可以提高機(jī)械強(qiáng)度和耐熱性，且玻纖增強(qiáng)pp塑膠原料的耐水蒸汽性、耐化學(xué)腐蝕性和耐蠕變性都很好，在許多場合可以作為工程塑料使用，如風(fēng)扇葉片、暖風(fēng)機(jī)格柵、葉輪泵、燈罩、電爐和加熱器外殼等等。</p><p style="text-indent:25px">pp塑膠原料的結(jié)晶度高，結(jié)構(gòu)規(guī)整，因而具有優(yōu)良的力學(xué)性能。pp塑膠原料力學(xué)性能的值高于聚乙烯，但在塑料材料中仍屬于偏低的品種，其拉伸強(qiáng)度*可達(dá)到30 MPa或稍高的水平。等規(guī)指數(shù)較大的pp塑膠原料具有較高的拉伸。強(qiáng)度，但隨等規(guī)指數(shù)的提高，材料的沖擊強(qiáng)度有所下降，但下降至某一數(shù)值后不再變化。溫度和加載速率對pp塑膠原料的韌性影響很大。當(dāng)溫度高于玻璃化溫度時，沖擊破壞呈韌性斷裂，低于玻璃化溫度呈脆性斷裂，且沖擊強(qiáng)度值大幅度下降。提高加載速率，可使韌性斷裂向脆性斷裂轉(zhuǎn)變的溫度上升。pp塑膠原料具有優(yōu)異的抗彎曲疲勞性，其制品在常溫下可彎折106次而不損壞。pp塑膠原料它的擊穿電壓很高，適合用作電氣配件等。</p><div

style="text-indent:25px">pp塑膠原料無毒、無味，密度小，強(qiáng)度、剛度、硬度耐熱性均優(yōu)于低壓聚乙烯,可在100℃左右使用。具有良好的介電性能和高頻絕緣性且不受濕度影響，但低溫時變脆，不耐磨、易老化。適于制作一般機(jī)械零件、耐腐蝕零件和絕緣零件。常見的酸、堿等有機(jī)溶劑對它幾乎不起作用，可用于食具。pp塑膠原料具有許多優(yōu)良特性：相對密度小，*為0.89-0.91，是塑料中輕的品種之一。良好的力學(xué)性能，除耐沖擊性外，其他力學(xué)性能均比聚乙烯好，成型加工性能好。具有較高的耐熱性，連續(xù)使用溫度可達(dá)110-120℃?；瘜W(xué)性能好，幾乎不吸水，與絕大多數(shù)化學(xué)藥品不反應(yīng)。質(zhì)地純凈，無毒性。電絕緣性好。pp塑膠原料制品的透明性比高密度聚乙烯制品的透明性好。pp塑膠原料在不受外力的條件下，150℃也不變形。杭州pp塑膠原料供應(yīng)</p><p style="text-indent:25px">pp塑膠原料成型特性：結(jié)晶料，吸濕性小，易發(fā)生融體破裂，長期與熱金屬接觸易分解。杭州pp塑膠原料供應(yīng)</p><p style="text-indent:25px">溫度和加載速率對pp塑膠原料的韌性影響很大。當(dāng)溫度高于玻璃化溫度時，沖擊破壞呈韌性斷裂，低于玻璃化溫度呈脆性斷裂，且沖擊強(qiáng)度值大幅度下降。提高加載速率，可使韌性斷裂向脆性斷裂轉(zhuǎn)變的溫度上升。pp塑膠原料具有優(yōu)異的抗彎曲疲勞性，其制品在常溫下可彎折106次而不損壞。但在室溫和低溫下，由于本身的分子結(jié)構(gòu)規(guī)整度高，所以抗沖擊強(qiáng)度較差。pp塑膠原料的化學(xué)穩(wěn)定性很好，除能被濃硫酸、濃硝酸侵蝕外，對其它各種化學(xué)試劑都比較穩(wěn)定，但低分子量的脂肪烴、芳香烴和氯化烴等能使pp塑膠原料軟化和溶脹，同時它的化學(xué)穩(wěn)定性隨結(jié)晶度的增加還有所提高，所以pp塑膠原料適合制作各種化工管道和配件，防腐蝕效果良好。杭州pp塑膠原料供應(yīng)</p></p><br
