什么是偶聯(lián)劑，其分子結(jié)構(gòu)特點(diǎn)，舉例說(shuō)明起作用機(jī)理。答：偶聯(lián)劑是指能改善填料與高分子材料之間界面特性的一類物質(zhì)。其分子結(jié)構(gòu)中存在兩種官能團(tuán)：一種可與高分子基體發(fā)生化學(xué)反應(yīng)或至少有好的相容性;另一種可與無(wú)機(jī)填料形成化學(xué)鍵。如：硅烷偶聯(lián)劑，通式可寫為RSiX3，其中R是與聚合物分子有親和力和反應(yīng)能力的活性官能團(tuán)，如乙烯基氯丙基、環(huán)氧基、甲基丙烯?；?、胺基和巰基等。X為能夠水解的烷氧基，如甲氧基、乙氧基等。 25，山東銻母粒廠家直銷.什么是發(fā)泡劑？答：發(fā)泡劑是一類能使處于一定黏度范圍內(nèi)的液態(tài)或塑性狀態(tài)的橡膠，山東銻母粒廠家直銷，塑料形成微孔結(jié)構(gòu)的物質(zhì)，山東銻母粒廠家直銷。物理發(fā)泡劑：依靠在發(fā)泡過(guò)程中本身物理狀態(tài)變化來(lái)達(dá)到發(fā)泡目地的一類化合物; 化學(xué)發(fā)泡劑：在一定溫度下會(huì)熱分解而產(chǎn)生一種或多種氣體，使聚合物發(fā)泡。</span> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山東銻母粒廠家直銷"

無(wú)機(jī)化學(xué)與有機(jī)化學(xué)發(fā)泡劑分解時(shí)各有何特點(diǎn)？答：有機(jī)發(fā)泡劑優(yōu)缺點(diǎn)：①在聚合物中分散性好;②分解溫度范圍較窄,易與控制;③所產(chǎn)生的N2氣不燃燒、不、不易液化,擴(kuò)散速度小,不容易從發(fā)泡體中逸出,因而法袍率高;④粒子小,發(fā)泡體的泡孔小;⑤品種較多;⑥發(fā)泡后殘?jiān)^多,有時(shí)高達(dá)70%-85%,這些殘?jiān)袝r(shí)會(huì)引起異臭,污染聚合材料或產(chǎn)生表面噴霜現(xiàn)象;⑦分解時(shí)一般為放熱反應(yīng)，如果所使用的發(fā)泡劑分解熱太高的話，就可能在發(fā)泡過(guò)程中造成發(fā)泡體系內(nèi)外較大的溫度梯度，有時(shí)造成內(nèi)部溫度過(guò)高而損壞聚合物的物化性能。⑧有機(jī)發(fā)泡劑多為易燃物，在貯存和使用時(shí)都應(yīng)注意防火。</span>

黑色母粒的相容性大決定色母粒質(zhì)量的因素之一，如果色母粒是使用切屑或再生料生產(chǎn)出來(lái)的，那么它可能含有污染物或其他不可熔化的聚合物。這會(huì)引起一些不可預(yù)料的、難于約束的麻煩，浪費(fèi)了**終消費(fèi)者的時(shí)間和原料。這時(shí)，可以選用打底樹脂來(lái)生產(chǎn)高質(zhì)量的色母粒，母粒在熔化過(guò)程中才有良好的相容性。質(zhì)量的色母粒可使用LLDPE、LDPE、HDPE、PP、PS、SAN、PA以及其他材料來(lái)生產(chǎn)。 </p> <p> 如果已注明工程級(jí)和嚴(yán)格的物理性能，那么特殊的聚合黑色母?？梢缘玫降?。幾間國(guó)際上大型的色母粒生產(chǎn)商，都在進(jìn)行研究，以圖生產(chǎn)出所謂的"全球性通用的黑色母。這些色母?？梢?**的和其他原料相容，具備良好的流變性，可靈活應(yīng)用。 </p> <p> <br /> </p></p><br
