玻(bo)纖增強PP產品工藝  

根據PP材料的(de)上述特點，鹽城噴絲地毯塑料地板，生產(chan)增強(qiang)PP時從玻(bo)(bo)纖(xian)(xian)口后(hou)到機頭(tou)段(duan)的(de)螺(luo)桿(gan)剪(jian)切很強(qiang)。要(yao)避免(mian)“玻(bo)(bo)纖(xian)(xian)不(bu)熔(rong)”的(de)現象除了保證螺(luo)桿(gan)玻(bo)(bo)纖(xian)(xian)口后(hou)面剪(jian)切強(qiang)之外，螺(luo)筒磨(mo)損大(da)(da)(da)小對其也影響很大(da)(da)(da)。當機臺磨(mo)損過(guo)大(da)(da)(da)時常(chang)常(chang)以降(jiang)低玻(bo)(bo)纖(xian)(xian)口后(hou)溫度(du)(du)(du)，特別(bie)時玻(bo)(bo)纖(xian)(xian)口至真空口之間的(de)溫度(du)(du)(du)，提(ti)高熔(rong)體粘度(du)(du)(du)來提(ti)高剪(jian)切，避免(mian)“玻(bo)(bo)纖(xian)(xian)不(bu)熔(rong)”。但玻(bo)(bo)纖(xian)(xian)口后(hou)溫度(du)(du)(du)不(bu)可降(jiang)低過(guo)大(da)(da)(da)以免(mian)玻(bo)(bo)纖(xian)(xian)剪(jian)切過(guo)碎，性能降(jiang)低。

碳(tan)(tan)纖(xian)(xian)(xian)維碳(tan)(tan)纖(xian)(xian)(xian)維具有強度高(gao)、模量高(gao)、耐(nai)高(gao)溫、導電等一(yi)系列性(xing)能，PVC噴絲(si)(si)地(di)(di)(di)(di)毯塑料地(di)(di)(di)(di)板廠商，首先(xian)在航(hang)空航(hang)天(tian)領(ling)域得到(dao)廣(guang)泛應用(yong)(yong)(yong)，PVC噴絲(si)(si)地(di)(di)(di)(di)毯塑料地(di)(di)(di)(di)板報價，近年(nian)來(lai)在運動器(qi)具和體育(yu)用(yong)(yong)(yong)品方面也廣(guang)泛采(cai)用(yong)(yong)(yong)。據預測，土(tu)木建筑、交通(tong)運輸(shu)、汽(qi)車(che)、能源等領(ling)域將會大規(gui)模采(cai)用(yong)(yong)(yong)工業級碳(tan)(tan)纖(xian)(xian)(xian)維。1997~2000年(nian)間，PVC噴絲(si)(si)地(di)(di)(di)(di)毯塑料地(di)(di)(di)(di)板廠家，宇(yu)航(hang)用(yong)(yong)(yong)碳(tan)(tan)纖(xian)(xian)(xian)維的(de)年(nian)增(zeng)長(chang)率估計為31%，而(er)工業用(yong)(yong)(yong)碳(tan)(tan)纖(xian)(xian)(xian)維的(de)年(nian)增(zeng)長(chang)率估計會達到(dao)130%。中國(guo)的(de)碳(tan)(tan)纖(xian)(xian)(xian)維總體水平(ping)還(huan)比較低，相(xiang)當(dang)于(yu)國(guo)外(wai)七十年(nian)代中、末期(qi)水平(ping)，與國(guo)外(wai)差距達20年(nian)左右(you)。國(guo)產碳(tan)(tan)纖(xian)(xian)(xian)維的(de)主要問題是性(xing)能不(bu)太穩定且離散系數(shu)大、無(wu)碳(tan)(tan)纖(xian)(xian)(xian)維、品種單一(yi)、規(gui)格不(bu)全、連續長(chang)度不(bu)夠、未(wei)經表面處理、價格偏高(gao)等。

玻纖增強(qiang)PP產品工藝

 影響玻纖剪切的條(tiao)件

物(wu)料(liao)在玻(bo)纖口(kou)處必(bi)須(xu)熔化了(le)85%以上，否則(ze)將(jiang)因玻(bo)纖與物(wu)料(liao)之(zhi)間嚴重的(de)摩檫(cha)使玻(bo)纖被剪切(qie)得過(guo)碎；玻(bo)纖口(kou)處溫(wen)(wen)度不能過(guo)低，必(bi)須(xu)在所生(sheng)產物(wu)料(liao)的(de)熔點以上，否則(ze)將(jiang)因料(liao)過(guo)冷，摩擦過(guo)大(da)使玻(bo)纖剪切(qie)過(guo)碎。一般工藝表上已(yi)經考慮到這(zhe)問題，生(sheng)產時需要(yao)注意(yi)是保證溫(wen)(wen)度波動不大(da)即(ji)可。
