甲(jia)基八溴醚是近年來開發(fa)的一種用(yong)(yong)于發(fa)泡聚(ju)苯乙(yi)烯阻(zu)燃的阻(zu)燃劑(ji)，由于其環(huan)保的特點，是斯德(de)哥爾摩(mo)公約列入(ru)禁用(yong)(yong)名(ming)錄的六溴環(huan)十二烷的優良替(ti)代品。八溴醚工業(ye)品的外觀為白色(se)或淡黃色(se)固體(ti)粉末(mo)，熔點范(fan)圍85～105℃，屬于鹵系(xi)阻(zu)燃劑(ji)，其溴含量(liang)為68%，屬通用(yong)(yong)添加型(xing)阻(zu)燃劑(ji)，主要用(yong)(yong)于聚(ju)丙烯(PP)、聚(ju)乙(yi)烯(PE)等聚(ju)烯烴(jing)類高(gao)分子材料的阻(zu)燃改性(xing)。

　　甲基(ji)八溴(xiu)醚生(sheng)產(chan)分(fen)為兩步——醚化(hua)(hua)和溴(xiu)化(hua)(hua);醚化(hua)(hua)是(shi)由(you)四溴(xiu)雙酚A、氫氧(yang)化(hua)(hua)鈉與甲基(ji)氯丙烯在溶(rong)(rong)(rong)(rong)劑(ji)中(zhong)(zhong)反應(ying)，通過(guo)(guo)過(guo)(guo)濾(lv)、洗(xi)滌(di)(di)、烘(hong)干(gan)(gan)(gan)得到(dao)中(zhong)(zhong)間體醚化(hua)(hua)物。溴(xiu)化(hua)(hua)是(shi)由(you)醚化(hua)(hua)物溶(rong)(rong)(rong)(rong)解(jie)在溶(rong)(rong)(rong)(rong)劑(ji)中(zhong)(zhong)與溴(xiu)素加成(cheng)(cheng)反應(ying)得到(dao)。現有(you)的(de)技術是(shi)醚化(hua)(hua)反應(ying)完(wan)成(cheng)(cheng)后(hou)，通過(guo)(guo)離(li)(li)心(xin)機離(li)(li)心(xin)過(guo)(guo)濾(lv)然后(hou)再用(yong)溶(rong)(rong)(rong)(rong)劑(ji)沖洗(xi)，再通過(guo)(guo)氣流(liu)烘(hong)干(gan)(gan)(gan)機或雙錐真空干(gan)(gan)(gan)燥機干(gan)(gan)(gan)燥，中(zhong)(zhong)間產(chan)品再投入反應(ying)釜用(yong)溶(rong)(rong)(rong)(rong)劑(ji)溶(rong)(rong)(rong)(rong)解(jie)。該(gai)過(guo)(guo)程(cheng)分(fen)四個工序：離(li)(li)心(xin)、洗(xi)滌(di)(di)、烘(hong)干(gan)(gan)(gan)、溶(rong)(rong)(rong)(rong)解(jie)，過(guo)(guo)程(cheng)復雜、用(yong)工多，離(li)(li)心(xin)過(guo)(guo)程(cheng)中(zhong)(zhong)溶(rong)(rong)(rong)(rong)劑(ji)會經過(guo)(guo)無(wu)組織排放，影響環(huan)境污(wu)染;物料(liao)洗(xi)滌(di)(di)時，由(you)于(yu)物料(liao)在離(li)(li)心(xin)機中(zhong)(zhong)物料(liao)洗(xi)滌(di)(di)效果(guo)差，并且無(wu)法(fa)進(jin)行(xing)烘(hong)干(gan)(gan)(gan)，物料(liao)會帶著部分(fen)溶(rong)(rong)(rong)(rong)劑(ji)，物料(liao)溶(rong)(rong)(rong)(rong)解(jie)后(hou)這部分(fen)溶(rong)(rong)(rong)(rong)劑(ji)會進(jin)入到(dao)廢水中(zhong)(zhong)無(wu)法(fa)回收，提高了(le)生(sheng)產(chan)成(cheng)(cheng)本。

　　針(zhen)對以上(shang)不足，無(wu)錫旭曄(ye)研發的(de)(de)阻(zu)燃劑過(guo)濾洗(xi)滌(di)一體機，甲(jia)基(ji)八(ba)溴醚后處理(li)過(guo)程(cheng)無(wu)需(xu)物料(liao)頻(pin)繁轉(zhuan)移(yi)，減少設(she)備使用量，減少員工(gong)的(de)(de)勞(lao)動強(qiang)度，提高工(gong)作效率;可(ke)以實現過(guo)程(cheng)中溶劑的(de)(de)回收，既減少環境污染，又可(ke)節約(yue)(yue)溶劑的(de)(de)使用，節約(yue)(yue)成本。

甲基(ji)八溴醚專用阻(zu)燃劑過濾洗滌一體機 工作原理(li)
