為什么塑料在加工或使用過(guò)程中極易帶靜電？答：由于其主體聚合物的分子鏈差不多均是共價(jià)鍵組成，既不能電離又不能傳遞電子。在其加工和制品的使用過(guò)程中，當(dāng)同其它物體或自身想接觸和摩擦?xí)r會(huì)因?yàn)殡娮拥牡檬Ф鴰щ?，并且難通過(guò)自身傳導(dǎo)而消失。15.橡膠硫化后，其結(jié)構(gòu)和性能通常發(fā)生何種變化？答：①硫化膠由線型變?yōu)槿痪W(wǎng)狀結(jié)構(gòu);②加熱不再流動(dòng);③不再溶于它的良溶劑中;④模量和硬度提高;⑤力學(xué)性能提高;⑥耐老化性能和化學(xué)穩(wěn)定性提高;⑦介質(zhì)性能可能下降。16.硫磺硫化與硫磺給予體硫化有何不同？答：①硫磺硫化：多硫鍵,耐熱、耐老化差，屈撓性好，長(zhǎng)久變形大;②硫磺給予體：?jiǎn)瘟蜴I多，耐熱、耐老化好。17，三氧化二銻母粒廠.硫化促進(jìn)劑起什么作用？答：提高橡膠制品的生產(chǎn)效率降低成本改善性能。能促進(jìn)硫化作用的物質(zhì)，三氧化二銻母粒廠?？煽s短硫化時(shí)間，降低硫化溫度，減少硫化劑用量和提高橡膠的物理機(jī)械性能等，三氧化二銻母粒廠。18.什么是焦燒現(xiàn)象？答：橡膠膠料在加工過(guò)程中產(chǎn)生的早期硫化的現(xiàn)象。</span>

母粒稱為塑料母?；蚰噶?。是一種塑料加工助劑。它由過(guò)量的化學(xué)助劑、載體樹脂和分散劑組成。阻燃母粒是用樹脂固定化阻燃劑制備的集料。母料中阻燃劑的濃度通常在50%到90%之間變化。阻燃母粒通常是將阻燃劑與樹脂載體及助劑混合，將阻燃劑熔融到樹脂基體中制成。阻燃母粒的優(yōu)點(diǎn)：1。與阻燃粉相比，它更易于操作、測(cè)量和運(yùn)輸。2。更好的生產(chǎn)環(huán)境，更衛(wèi)生環(huán)保；3、經(jīng)過(guò)一輪擠出分散后，使用時(shí)間分割會(huì)更好，可以提高生產(chǎn)效率和材料性能；4、特別適用于某些擠出領(lǐng)域，已加工分散；5。各種添加劑可按比例制成特定的阻燃功能母粒；6。母粒大小與樹脂相似，阻燃劑分層，加料不均勻。阻燃母粒的缺點(diǎn)：1。阻燃母粒需要載體。載體樹脂的引入會(huì)影響某些材料的性能； </p> <p> 以上就是小編為大家整理關(guān)于阻燃母粒的相關(guān)咨詢，通過(guò)本次內(nèi)容的分享，大家對(duì)阻燃母粒有了一定的認(rèn)知，如果您想要更深入的了解阻燃母粒的市場(chǎng)資訊，可以聯(lián)系我們公司的業(yè)務(wù)員，或者到實(shí)地考察，共同探討交流。 </p><div

銻鹵阻燃體系如何發(fā)生協(xié)同作用？答：銻常用的是Sb2O3，鹵化物常用的是有機(jī)鹵化物。Sb2O3/機(jī)有鹵化物一起使用，主要認(rèn)為是因?yàn)樗c鹵化物放出的鹵化氫作用。且產(chǎn)物熱分解成SbCl3，它是沸點(diǎn)不太高的揮發(fā)性氣體，這種氣體相對(duì)密度大,能長(zhǎng)時(shí)間停留在燃燒區(qū)內(nèi)稀釋可燃性氣體，隔絕空氣，起到阻烯作用;其次，它能捕獲燃燒性游離基,起以抵抗火焰的作用。另外，SbCl3在火焰的上空凝結(jié)成液滴式固體微粒，其壁效應(yīng)散射大量的熱量，使燃燒速度減速緩或停止。一般來(lái)說(shuō)，氯與金屬原子以3:1較為合適。11.根據(jù)目前研究，阻燃劑的作用機(jī)理有哪些？答：①阻燃劑在燃燒溫度下的分解產(chǎn)物形成不揮發(fā)不氧化的玻璃狀薄膜，可隔絕空氣反射能量或具有低的導(dǎo)熱系數(shù)。②阻燃劑受熱分解生成不燃燒氣體從而稀釋可燃性氣體，沖淡燃燒區(qū)氧的濃度;③阻燃劑溶化分解吸熱消耗熱量;④阻燃劑促使塑料表面形成一層多孔的隔熱穩(wěn)炭層,阻止熱傳導(dǎo)及繼續(xù)燃燒。
