玻纖增強PP產品工藝    

  生產(chan)增強PP產(chan)品時(shi)，玻(bo)(bo)纖很難(nan)剪斷(duan)(duan)，并且與所用(yong)的(de)(de)玻(bo)(bo)纖有關。生產(chan)不(bu)順(shun)時(shi)會出現(xian)這(zhe)樣(yang)的(de)(de)現(xian)象：因(yin)玻(bo)(bo)纖過長，常把模(mo)(mo)頭(tou)模(mo)(mo)孔堵住，引起(qi)斷(duan)(duan)條(tiao)(tiao)(tiao)，判斷(duan)(duan)方法：在模(mo)(mo)頭(tou)模(mo)(mo)孔處(chu)可(ke)看到一團(tuan)(tuan)團(tuan)(tuan)的(de)(de)玻(bo)(bo)纖，空(kong)氣(qi)纖維床(chuang)(chuang)墊多少錢(qian)，成品的(de)(de)截面處(chu)可(ke)明顯看到成團(tuan)(tuan)的(de)(de)玻(bo)(bo)纖或(huo)在粒子的(de)(de)表層(ceng)有切不(bu)斷(duan)(duan)的(de)(de)玻(bo)(bo)纖，料(liao)(liao)條(tiao)(tiao)(tiao)軟(ruan)而不(bu)脆(cui)，料(liao)(liao)條(tiao)(tiao)(tiao)不(bu)能完全(quan)拗(ao)(ao)(ao)(ao)斷(duan)(duan)，空(kong)氣(qi)纖維床(chuang)(chuang)墊廠(chang)家價(jia)格，拗(ao)(ao)(ao)(ao)后將有一層(ceng)連皮。或(huo)從拗(ao)(ao)(ao)(ao)斷(duan)(duan)的(de)(de)聲(sheng)音可(ke)判斷(duan)(duan)出來(lai)：增強差的(de)(de)料(liao)(liao)條(tiao)(tiao)(tiao)拗(ao)(ao)(ao)(ao)斷(duan)(duan)時(shi)的(de)(de)聲(sheng)音較(jiao)(jiao)沉，增強好(hao)的(de)(de)料(liao)(liao)條(tiao)(tiao)(tiao)拗(ao)(ao)(ao)(ao)斷(duan)(duan)時(shi)的(de)(de)聲(sheng)音較(jiao)(jiao)脆(cui)。俗稱“玻(bo)(bo)纖不(bu)熔”。若生產(chan)時(shi)斷(duan)(duan)條(tiao)(tiao)(tiao)嚴重，空(kong)氣(qi)纖維床(chuang)(chuang)墊批發，并且料(liao)(liao)條(tiao)(tiao)(tiao)較(jiao)(jiao)軟(ruan)，則(ze)成品的(de)(de)性(xing)能一定會降低。
