無機阻燃劑與無鹵阻燃劑的(de)區(qu)別(bie)有(you)(you)(you)哪些？我們(men)知道無(wu)(wu)機阻(zu)燃(ran)(ran)劑主要以氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鋁(lv)和(he)(he)氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鎂(mei)(mei)為(wei)(wei)(wei)主。 目前，國(guo)外基本(ben)采(cai)用無(wu)(wu)機阻(zu)燃(ran)(ran)劑。 其中(zhong)，美國(guo)、日(ri)本(ben)和(he)(he)西歐的(de)無(wu)(wu)機阻(zu)燃(ran)(ran)劑消(xiao)費量(liang)比(bi)較大。 氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鋁(lv)和(he)(he)氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鎂(mei)(mei)都是(shi)白色粉末，氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鋁(lv)的(de)脫水溫(wen)度(du)(du)為(wei)(wei)(wei)200℃，氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鎂(mei)(mei)的(de)脫水溫(wen)度(du)(du)為(wei)(wei)(wei)340℃。氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鎂(mei)(mei)的(de)熱分解溫(wen)度(du)(du)高，比(bi)氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鋁(lv)高140℃，可以使添加氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鎂(mei)(mei)的(de)合成材料能承受更高的(de)加工溫(wen)度(du)(du)，有(you)(you)(you)利(li)于(yu)加快(kuai)擠(ji)出(chu)速度(du)(du)，縮短成型時間(jian)，提高阻(zu)燃(ran)(ran)效率(lv)。氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鎂(mei)(mei)粒度(du)(du)細，對設(she)(she)備(bei)磨(mo)損小，有(you)(you)(you)利(li)于(yu)延長(chang)加工設(she)(she)備(bei)的(de)使用壽命(ming)。由(you)于(yu)氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鎂(mei)(mei)與氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鋁(lv)相比(bi)具有(you)(you)(you)諸多優點，因此氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鎂(mei)(mei)的(de)比(bi)重越來越大。與同類無(wu)(wu)機阻(zu)燃(ran)(ran)劑相比(bi)，氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鎂(mei)(mei)具有(you)(you)(you)更好的(de)抑煙效果。氫(qing)(qing)(qing)氧(yang)(yang)(yang)(yang)(yang)化(hua)(hua)(hua)(hua)鎂(mei)(mei)在(zai)生產、使用和(he)(he)處置過程中(zhong)不排放有(you)(you)(you)害(hai)物質(zhi)，還可以中(zhong)和(he)(he)燃(ran)(ran)燒過程中(zhong)產生的(de)酸性(xing)(xing)和(he)(he)腐蝕性(xing)(xing)氣體。

在無鹵阻燃劑中(zhong)，紅(hong)(hong)磷(lin)是一(yi)種(zhong)較好的(de)阻(zu)(zu)燃劑(ji)，具(ju)有(you)添加量(liang)少(shao)、用(yong)途廣等(deng)優(you)點(dian)。普通紅(hong)(hong)磷(lin)易吸(xi)潮(chao)，與高分子材(cai)料相(xiang)(xiang)容(rong)(rong)性(xing)差，特(te)別容(rong)(rong)易自燃，無(wu)法實際(ji)使用(yong)。微膠囊(nang)化(hua)紅(hong)(hong)磷(lin)阻(zu)(zu)燃劑(ji)降(jiang)低了紅(hong)(hong)磷(lin)的(de)活性(xing)，解(jie)決(jue)了相(xiang)(xiang)容(rong)(rong)性(xing)問題，紅(hong)(hong)磷(lin)含量(liang)在(zai)85%左(zuo)右，但自燃問題沒有(you)得到有(you)效解(jie)決(jue)，揚塵(chen)污染嚴重。紅(hong)(hong)磷(lin)母粒是紅(hong)(hong)磷(lin)與氫(qing)氧化(hua)鋁(lv)、膨脹石墨等(deng)無(wu)機阻(zu)(zu)燃劑(ji)復(fu)合使用(yong)，以基(ji)體(ti)樹脂為載體(ti)的(de)暗紅(hong)(hong)色顆(ke)粒，解(jie)決(jue)了安全問題，具(ju)有(you)低煙(yan)、阻(zu)(zu)燃效率高、無(wu)粉塵(chen)污染、加工(gong)性(xing)能(neng)優(you)良、密(mi)度低、熱穩定性(xing)好、制品物(wu)理(li)性(xing)能(neng)下(xia)降(jiang)少(shao)、加工(gong)過程中(zhong)不結(jie)霜、不遷移、不腐(fu)蝕模具(ju)等(deng)特(te)點(dian)。高耐漏電(dian)(dian)痕指數（CTI）在(zai)電(dian)(dian)子電(dian)(dian)氣應用(yong)中(zhong)具(ju)有(you)明顯優(you)勢(shi)。
