甲基八(ba)溴(xiu)醚是近年來開發的(de)(de)一種用(yong)于(yu)發泡聚苯乙烯(xi)(xi)阻(zu)燃的(de)(de)阻(zu)燃劑(ji)，由(you)于(yu)其(qi)環保的(de)(de)特點(dian)，是斯德哥(ge)爾摩公約列入禁用(yong)名錄的(de)(de)六溴(xiu)環十二烷的(de)(de)優良替代品。八(ba)溴(xiu)醚工業(ye)品的(de)(de)外觀(guan)為白色(se)或淡黃(huang)色(se)固體粉末，熔點(dian)范圍85～105℃，屬于(yu)鹵系阻(zu)燃劑(ji)，其(qi)溴(xiu)含量為68%，屬通用(yong)添加型阻(zu)燃劑(ji)，主要用(yong)于(yu)聚丙烯(xi)(xi)(PP)、聚乙烯(xi)(xi)(PE)等聚烯(xi)(xi)烴類高分子材料的(de)(de)阻(zu)燃改性。

　　甲(jia)(jia)基八溴(xiu)醚(mi)生(sheng)(sheng)產分(fen)為兩步——醚(mi)化(hua)和(he)溴(xiu)化(hua);醚(mi)化(hua)是(shi)(shi)(shi)由(you)(you)四溴(xiu)雙酚A、氫氧化(hua)鈉(na)與(yu)甲(jia)(jia)基氯丙烯在(zai)溶(rong)(rong)(rong)劑(ji)中(zhong)(zhong)(zhong)(zhong)反應，通(tong)過(guo)(guo)(guo)過(guo)(guo)(guo)濾(lv)、洗(xi)滌(di)(di)、烘(hong)干得到中(zhong)(zhong)(zhong)(zhong)間體醚(mi)化(hua)物(wu)(wu)。溴(xiu)化(hua)是(shi)(shi)(shi)由(you)(you)醚(mi)化(hua)物(wu)(wu)溶(rong)(rong)(rong)解(jie)在(zai)溶(rong)(rong)(rong)劑(ji)中(zhong)(zhong)(zhong)(zhong)與(yu)溴(xiu)素加成反應得到。現有的技術是(shi)(shi)(shi)醚(mi)化(hua)反應完成后(hou)，通(tong)過(guo)(guo)(guo)離(li)(li)心機(ji)(ji)離(li)(li)心過(guo)(guo)(guo)濾(lv)然后(hou)再(zai)(zai)用溶(rong)(rong)(rong)劑(ji)沖洗(xi)，再(zai)(zai)通(tong)過(guo)(guo)(guo)氣(qi)流烘(hong)干機(ji)(ji)或雙錐真空干燥機(ji)(ji)干燥，中(zhong)(zhong)(zhong)(zhong)間產品(pin)再(zai)(zai)投入反應釜用溶(rong)(rong)(rong)劑(ji)溶(rong)(rong)(rong)解(jie)。該過(guo)(guo)(guo)程分(fen)四個工序：離(li)(li)心、洗(xi)滌(di)(di)、烘(hong)干、溶(rong)(rong)(rong)解(jie)，過(guo)(guo)(guo)程復雜(za)、用工多，離(li)(li)心過(guo)(guo)(guo)程中(zhong)(zhong)(zhong)(zhong)溶(rong)(rong)(rong)劑(ji)會經(jing)過(guo)(guo)(guo)無(wu)組織排放，影響環境污(wu)染;物(wu)(wu)料洗(xi)滌(di)(di)時，由(you)(you)于物(wu)(wu)料在(zai)離(li)(li)心機(ji)(ji)中(zhong)(zhong)(zhong)(zhong)物(wu)(wu)料洗(xi)滌(di)(di)效果差(cha)，并且無(wu)法進行烘(hong)干，物(wu)(wu)料會帶著(zhu)部(bu)分(fen)溶(rong)(rong)(rong)劑(ji)，物(wu)(wu)料溶(rong)(rong)(rong)解(jie)后(hou)這部(bu)分(fen)溶(rong)(rong)(rong)劑(ji)會進入到廢水中(zhong)(zhong)(zhong)(zhong)無(wu)法回收，提高了生(sheng)(sheng)產成本。

　　針對以(yi)上不足，無(wu)錫旭曄研發的阻燃劑(ji)過濾洗(xi)滌一(yi)體(ti)機，甲基八溴醚(mi)后處(chu)理過程無(wu)需(xu)物料頻繁(fan)轉移，減(jian)少設(she)備使用(yong)量(liang)，減(jian)少員(yuan)工(gong)的勞動強度，提高工(gong)作效率;可以(yi)實現過程中溶劑(ji)的回收，既(ji)減(jian)少環境污染(ran)，又可節約溶劑(ji)的使用(yong)，節約成本。

甲(jia)基八溴(xiu)醚專用(yong)阻燃劑過濾洗滌一體機(ji) 工作原理

　　過濾洗滌干燥二合(he)一是在一密閉(bi)容器(qi)內先(xian)后完成攪拌(ban)、反應、過濾、清洗、脫液等(deng)(deng)工藝過程(cheng)。具有結構簡單、工藝流程(cheng)簡化、生(sheng)產效率高、無交(jiao)叉污染、物(wu)料(liao)(liao)更(geng)換便捷，自動化程(cheng)度(du)高等(deng)(deng)特(te)(te)點。同時可大大降(jiang)低(di)所需潔凈(jing)廠房(fang)的(de)體積，基礎投資費(fei)低(di)。廣泛應用于制藥(yao)、化工、食品、染料(liao)(liao)等(deng)(deng)行業，尤為適合(he)潔凈(jing)度(du)要求高，小批(pi)量多產品種及特(te)(te)大批(pi)量的(de)生(sheng)產場(chang)合(he)。

甲基八溴醚專用阻燃(ran)劑(ji)過濾洗(xi)滌一體機 設備結構
