PA6尼龍樹(shù)脂、汽車(chē)塑料注塑件、玻璃纖維增強(qiáng)材料

發(fā)布于2025-09-23 11:45:22 點(diǎn)擊：0

PA6尼龍樹(shù)脂為半透明或不透明乳白色結(jié)晶形聚合物，燃燒鑒別方法：藍(lán)底黃火焰，燒植物味，溶劑實(shí)驗(yàn)：
耐環(huán)己酮和芳香溶劑，密度：(g/cm3) 1.14-1.15，平衡吸水率：3.5%，具有良好的耐磨性、自潤(rùn)滑性和耐溶劑性。
干燥處理：由于PA6很容易吸收水分，因此加工前的干燥特別要注意，如果材料是用防水材料包裝供應(yīng)的，則容器應(yīng)保持密閉。
如果濕度大于0.2%，建議在80℃以上的熱空氣中干燥16小時(shí)。如果材料已經(jīng)在空氣中暴露超過(guò)8小時(shí)，建議進(jìn)行溫度為105℃，8小時(shí)以上的真空烘干。
熔融溫度：230-280℃，對(duì)于增強(qiáng)品種為250-280℃。
模具溫度：80-90℃，模具溫度很顯著地影響結(jié)晶度，而結(jié)晶度又影響著塑件的機(jī)械特性。
對(duì)于結(jié)構(gòu)部件來(lái)說(shuō)結(jié)晶度很重要，因此建議模具溫度為80-90℃。對(duì)于薄壁的、流程較長(zhǎng)的塑件也建議施用較高的模具溫度。
增大模具溫度可以提高塑件的強(qiáng)度和剛度，但卻降低了韌性。
如果壁厚大于3mm，建議使用20-40℃的低溫模具。
對(duì)于玻璃纖維增強(qiáng)材料模具溫度應(yīng)大于80℃。
PA6在汽車(chē)上應(yīng)用廣泛，汽車(chē)是塑料重要和快速增長(zhǎng)的市場(chǎng)，PA6具有良好的綜合性能，密度低，容易成型，設(shè)計(jì)自由度大，隔熱絕緣，而且在模具和組裝成本上也有明顯的優(yōu)勢(shì)。
