木粉填充(chong)聚丙(bing)烯的生產工藝介紹

　　木粉來自范圍(wei)比(bi)較廣，產(chan)品性能優良。因此，利用木(mu)(mu)粉填充聚丙(bing)烯成為近年來研究的(de)熱點。木(mu)(mu)粉廠在這(zhe)方面也做了(le)很多努(nu)力。小編今天就(jiu)給(gei)大家簡單介紹一(yi)下木(mu)(mu)粉填充聚丙(bing)烯的(de)生(sheng)產(chan)工(gong)藝。

　　木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)廠(chang)(chang)可以(yi)在木(mu)(mu)(mu)(mu)材加(jia)工(gong)(gong)(gong)中使(shi)用(yong)木(mu)(mu)(mu)(mu)屑、鋸末和廢(fei)棄的(de)(de)木(mu)(mu)(mu)(mu)屑。用(yong)低值芯材壓(ya)碎后(hou)(hou)(hou)可用(yong)于(yu)聚丙烯填料。木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)的(de)(de)粒度要求小于(yu)10微米。上述物質的(de)(de)化學成分(fen)不同，通常以(yi)纖(xian)維素、半纖(xian)維素和木(mu)(mu)(mu)(mu)質素為主。因此，木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)廠(chang)(chang)應在加(jia)工(gong)(gong)(gong)時進(jin)(jin)行(xing)分(fen)類加(jia)工(gong)(gong)(gong)。木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)在木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)廠(chang)(chang)加(jia)工(gong)(gong)(gong)后(hou)(hou)(hou)，木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)應充分(fen)加(jia)熱，以(yi)除(chu)去(qu)揮發性物質，提高木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)的(de)(de)熱穩定(ding)性。填好后(hou)(hou)(hou)可以(yi)穩定(ding)。經過上述干燥處理后(hou)(hou)(hou)，木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)廠(chang)(chang)還對木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)進(jin)(jin)行(xing)篩分(fen)，根據(ju)木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)的(de)(de)加(jia)工(gong)(gong)(gong)條件，主要選(xuan)用(yong)40目(mu)左右的(de)(de)篩子。木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)加(jia)工(gong)(gong)(gong)后(hou)(hou)(hou)，在20升的(de)(de)高速(su)捏(nie)合(he)(he)機中加(jia)入3公(gong)斤木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)，加(jia)入雙(shuang)硬脂(zhi)(zhi)(zhi)酸(suan)甘油酯，溫度保持在70攝氏度至80攝氏度，以(yi)1760轉/分(fen)攪(jiao)拌(ban)。4分(fen)鐘后(hou)(hou)(hou)，以(yi)875轉/分(fen)攪(jiao)拌(ban)2分(fen)鐘，直到(dao)木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)冷卻，得到(dao)浸漬(zi)雙(shuang)硬脂(zhi)(zhi)(zhi)酸(suan)鹽(yan)的(de)(de)木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)。制備了幾(ji)批不同雙(shuang)硬脂(zhi)(zhi)(zhi)酸(suan)含量(liang)的(de)(de)木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)，然(ran)后(hou)(hou)(hou)將浸漬(zi)木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)與聚丙烯混合(he)(he)，除(chu)去(qu)浸漬(zi)劑后(hou)(hou)(hou)純(chun)木(mu)(mu)(mu)(mu)粉(fen)(fen)(fen)(fen)與雙(shuang)硬脂(zhi)(zhi)(zhi)酸(suan)甘油酯的(de)(de)比例為36.4:60。組(zu)后(hou)(hou)(hou)進(jin)(jin)行(xing)造(zao)粒成型。

　　經過以上介(jie)紹，大家應該有所了解，這道(dao)工(gong)序的(de)關鍵是木(mu)粉廠開始加工(gong)木(mu)粉，隨(sui)后的(de)灌裝工(gong)序相對就簡單了。
