style="text-indent:25px">塑料模具基礎(chǔ)知識(shí)：一﹑塑料的分子結(jié)構(gòu)：塑料主要成份是樹(shù)脂﹐樹(shù)脂有天然樹(shù)脂和合成樹(shù)脂兩種。二﹑塑料的成份：1.樹(shù)脂：主要作用是將塑料的其它成份加以粘合，并決定塑料的類型(熱塑性或熱固性)和主要性能，如機(jī)械﹑物理﹑電﹑化學(xué)性能等。樹(shù)脂在塑料中的比例一般為40~65%。2.填充劑：又稱填料，正確地選擇填充劑，可以改善塑料的性能和擴(kuò)大它的使用范圍。3.增塑劑：有些樹(shù)脂的可塑性很小，柔軟性也很差，為了降低樹(shù)脂的熔融粘度和熔融溫度，改善其成型加工性能，改進(jìn)塑料的柔韌性，彈性以及其它各種必要的性能，通常加入能入樹(shù)脂相容的不易揮發(fā)的高沸點(diǎn)的有機(jī)化合物。這類物質(zhì)稱增塑劑。增塑常是一種高沸點(diǎn)液納或熔點(diǎn)固體的酯類化合物，臺(tái)州管件塑料模具采購(gòu)。4.著色劑：又稱色料，主要是起美觀和裝飾作用，包括涂料兩部分，臺(tái)州管件塑料模具采購(gòu)。5.穩(wěn)定劑：凡能陰緩塑料變質(zhì)的物質(zhì)稱穩(wěn)定劑，分光穩(wěn)定劑﹑熱穩(wěn)定劑﹑抗氧劑。6.潤(rùn)滑劑：改善塑料熔體的流動(dòng)性，臺(tái)州管件塑料模具采購(gòu)，減少或避免對(duì)設(shè)備或模具的磨擦和粘附，以及改進(jìn)塑件的表面光潔度。塑料注射模具對(duì)應(yīng)的加工設(shè)備是塑料注射成型機(jī)。臺(tái)州管件塑料模具采購(gòu)</p><div
