style="text-indent:25px">聚碳酸酯的制法之酯交換法：原理與生產(chǎn)滌綸聚酯的酯交換法相似。雙酚A與碳酸二苯酯熔融縮聚，進(jìn)行酯交換，在高溫減壓條件下不斷排除苯酚，提高反應(yīng)程度和分子量。酯交換法需用催化劑，分兩個(gè)階段進(jìn)行：第一階段，溫度180—200℃，壓力270—400Pa，反應(yīng)1—3h，轉(zhuǎn)化率為80%—90%；第二階段，290—300℃，130Pa以下，加深反應(yīng)程度。起始碳酸二苯酯應(yīng)過量，經(jīng)酯交換反應(yīng)，排出苯酚，由苯酚排出量來調(diào)節(jié)兩基團(tuán)數(shù)比，控制分子量。苯酚沸點(diǎn)高，從高粘熔體中心脫除并不容易。與滌綸聚酯相比，聚碳酸酯的熔體粘度要高得多，例如分子量3萬，300℃時(shí)的粘度達(dá)600Pa·s，對反應(yīng)設(shè)備的攪拌混合和傳熱有著更高的要求。因此，酯交換法聚碳酸酯的分子量受到了限制，多不超出3萬。徐州高耐磨PC廠家推薦聚碳酸酯的熔融黏度較高，成型薄壁或形狀復(fù)雜的制件需要較大的注射壓力。</p><div

style="text-indent:25px">聚碳酸酯具有良好的抗沖擊、抗熱畸變性能，而且耐候性好、硬度高，因此適用于生產(chǎn)轎車和輕型卡車的各種零部件，其主要集中心在照明系統(tǒng)、儀表板、加熱板、除霜器及聚碳酸酯合金制的保險(xiǎn)杠等。根據(jù)發(fā)達(dá)國家數(shù)據(jù)，聚碳酸酯在電子電氣、汽車制造業(yè)中心使用比例在40%～50%，中心國在該領(lǐng)域的使用比例只占10%左右，電子電氣和汽車制造業(yè)是中心國迅速發(fā)展的支柱產(chǎn)業(yè)，未來這些領(lǐng)域?qū)厶妓狨サ男枨罅繉⑹蔷薮蟮摹Ｖ行膰嚳偭慷?，需求量大，因而聚碳酸酯在這一領(lǐng)域的應(yīng)用是極有拓展?jié)摿Φ?。由于聚碳酸酯制品可?jīng)受蒸汽、清洗劑、加熱和大劑量輻射消毒，且不發(fā)生變黃和物理性能下降，因而被普遍應(yīng)用于人工腎血液透析設(shè)備和其他需要在透明、直觀條件下操作并需反復(fù)消毒的醫(yī)療設(shè)備中心。如生產(chǎn)高壓注射器、外科手術(shù)面罩、一次性牙科用具、血液分離器等。</p><p style="text-indent:25px">壓延方法：片材的壓延方法有水平方向擠出壓延片，傾斜方向擠出壓延片，向下或向上擠出壓延片。但目前較好的是輥筒傾斜壓延法。典型的PC板擠出條件：機(jī)簡溫度260、 280、300℃，機(jī)頭溫度2801C、壓延輥筒溫度：上輥121-135℃、中心輥129-139℃、下輥132--150℃，螺桿轉(zhuǎn)速12-24轉(zhuǎn)/分，過濾網(wǎng)組40/60/100目。PC板可用于汽車，飛機(jī)風(fēng)擋玻璃，波紋板，折板，建筑窗玻璃，體育設(shè)施天棚玻璃等。其他：PC可和ABS共混，提高沖擊強(qiáng)度，ABS添加量為50%時(shí)，提高幅度較大。ABS含量過少時(shí)如3%，沖擊強(qiáng)度反而下降。PC可和HDPE共混，共中心HDPE含量為30%時(shí)共混效采較好，可改善沖擊強(qiáng)度，加工流動性能提高，易于充模。LDPE共餛效果很差，出現(xiàn)分層，不能使用。聚碳酸酯熱變形溫度：135°C

style="text-indent:25px">pc應(yīng)用領(lǐng)域：1、航空航天：隨著航空、航天技術(shù)的迅速發(fā)展，對飛機(jī)和航天器中心各部件的要求不斷提高，使得PC在該領(lǐng)域的應(yīng)用也日趨增加。據(jù)統(tǒng)計(jì)，*一架波音型飛機(jī)上所用聚碳酸酯部件就達(dá)2500個(gè)，單機(jī)耗用聚碳酸酯約2噸。而在宇宙飛船上則采用了數(shù)百個(gè)不同構(gòu)型并由玻璃纖維增強(qiáng)的聚碳酸酯部件及宇航員的防護(hù)用品等。2、包裝領(lǐng)域：在包裝領(lǐng)域出現(xiàn)的新增長點(diǎn)是可重復(fù)消毒和使用的各種型號的儲水瓶。由于聚碳酸酯制品具有質(zhì)量輕，抗沖擊和透明性好，用熱水和腐蝕性溶液洗滌處理時(shí)不變形且保持透明的優(yōu)點(diǎn)，一些領(lǐng)域PC瓶已完全取代玻璃瓶。據(jù)預(yù)測，隨著人們對飲用水質(zhì)量重視程度的不斷提高，聚碳酸酯在這方面的用量增長速度將保持在10%以上，預(yù)計(jì)到2005年將達(dá)到6萬噸。聚碳酸酯的電氣特性優(yōu)。常州環(huán)保PC多少錢</p><p

style="text-indent:25px">為什么聚碳酸酯這么好用？只有了解了聚碳酸酯的性能，才會知道它的應(yīng)用市場。1、光學(xué)特性。它的透光率在90%左右，接近于玻璃但是又比玻璃輕，不易碎，易于加工。有人會以為這就是所謂的“有機(jī)玻璃”，其實(shí)不然！我們所說的有機(jī)玻璃的學(xué)名是“聚甲基丙烯酸甲酯”。有機(jī)玻璃雖然也是透明材料，甚至光學(xué)特性比聚碳酸酯還要優(yōu)越，但是，它的力學(xué)性能與耐熱性能比聚碳酸酯相差太多，而且還不防火。所以就綜合性能而言，聚碳酸酯更較全，應(yīng)用也更為普遍。2、力學(xué)性能。聚碳酸酯是剛性與韌性的有機(jī)結(jié)合體。一般而言，一種材料剛性很好的話，它就會很脆，往地上一摔就會碎。但聚碳酸酯雖有很好的剛性，很難將其折彎，它的韌性卻也相當(dāng)好，由其制成的產(chǎn)品，即使有重物從高處落在其上，也不容易破碎。例如，4公斤的圓球從0.1米高處落在1.2cm厚的聚碳酸酯板上，聚碳酸酯板能夠完好無損。常州環(huán)保PC多少錢</p><p
