style="text-indent:25px">聚對(duì)苯二甲酸乙二醇酯PET和PBT的區(qū)別:1.相同特征含有剛性的亞苯基、極性酯基、柔性的亞甲基，總體上表現(xiàn)出較大的剛性，使其具有較高玻璃化溫度和較高的熔融溫度，酯基使聚合物具有一定的吸水性、水解性。熱塑性線形聚合物，結(jié)構(gòu)規(guī)整，具有結(jié)晶能力。PET與PBT都是乳白色結(jié)晶型固體或無(wú)色透明的無(wú)定形的固體。PET 與 PBT 的力學(xué)性能PBT具有突出的強(qiáng)韌性，未增強(qiáng)的聚合物的主要應(yīng)用形式是薄膜和纖維。其力學(xué)性能受其結(jié)晶度的大小、形態(tài)及取向影響。例如：未取向薄膜的拉伸強(qiáng)度可達(dá)到175~176MPa；經(jīng)過(guò)拉伸定向，拉伸強(qiáng)度可達(dá)到280MPa。PBT拉伸強(qiáng)度、壓縮強(qiáng)度、彎曲強(qiáng)度、模量等不如PET，韌性比PET好。但經(jīng)過(guò)玻璃纖維增強(qiáng)后力學(xué)性能大幅度提高，增較好果超過(guò)玻璃纖維增強(qiáng)的POM、PC、PPO、PA等許多工程塑料。</p><p style="text-indent:25px">聚對(duì)苯二甲酸乙二醇酯：其主要原因就是延伸過(guò)程可增強(qiáng)其耐熱性、強(qiáng)度和剛性。PBT注塑之前一定要在110～120℃的溫度下干燥3小時(shí)左右，成型加工溫度為250～270℃，模溫控制在50～75℃為宜。因該料從熔融狀態(tài)一經(jīng)冷卻，則會(huì)立即凝固結(jié)晶，故其冷卻時(shí)間較短;若噴嘴溫度控制不當(dāng)(偏低)，流道(水口)易冷卻固化，會(huì)出現(xiàn)堵嘴現(xiàn)象。若料筒溫度超過(guò)275℃或熔料在料筒中停留時(shí)間超過(guò)30分鐘，易引起材料分解變脆。PBT注塑時(shí)需用較大水口進(jìn)膠，不宜使用熱流道系統(tǒng)，模具排氣要良好，宜用“高速、中壓、中溫”的條件成型加工，防火料或加玻纖的PBT水口料不宜再回收利用，停機(jī)時(shí)需用PE或PP料及時(shí)清洗料管，以免碳化。聚丁烯對(duì)苯二甲酸酯時(shí)存放過(guò)程當(dāng)中就一定要多進(jìn)行查看。</p><div

style="text-indent:25px">PBT材料使用注意事項(xiàng)：射出速度:1.較快的充填速度,一般會(huì)使流程加長(zhǎng),適合填充薄壁型材,并形成叫好的表面光潔度。2.對(duì)于厚壁制品,慢速充填有助于減少空隙。3.當(dāng)使用窄澆口時(shí),壁厚段的充填速度應(yīng)減低,以幫助保壓。4.對(duì)于小澆口(針尖形澆口)的制件,建議采用程序注射,開始時(shí) 可使用較慢的注射速度,一減少剪切,漩紋和物料的燒結(jié)焦。5.通常我們建議PBT采用中高速的注射速度,以便提高表面光澤度和提高接合線強(qiáng)度。注射壓力:1.注射壓力的選用原則為:較好選用能滿足性能,外觀和模塑循環(huán)的較低壓力。2.PBT材料屬易流動(dòng)材料,通常選用中等壓力。3.對(duì)于充填構(gòu)造復(fù)雜或薄壁的制品時(shí),需要中等至較高的注射壓力。4.對(duì)非增強(qiáng)規(guī)格通常壓力為55~70Mpa,對(duì)增強(qiáng)規(guī)格通常壓力為 65~120Mpa。5.正常的情況下,合適的保壓壓力為注射壓力的60~80%。聚丁烯對(duì)苯二甲酸酯具有強(qiáng)度高、彈性好、熱定型性能優(yōu)良、耐熱性好、耐酸堿等性能。美國(guó)杜邦PBTLW9030FR</p><p
