1. Ukuxuba
Uma kuqhathaniswa nezinhlobo zendabuko zerabha ye-chloroprene. I-polyethylene e-chlorine ayidingi ukwenziwa ipulasitiki futhi ayidingi ukugcinwa ngemva kokwenziwa ipulasitiki. Izithasiselo zesimo soketshezi kufomula ye-polyethylene e-chlorine zingavuselelwa futhi zimuncwe ngezinye izimpushana ngesikhathi senqubo yokuhlanganisa, okungagwema ukuhlanza nokuconsa ngesikhathi senqubo yokuxuba yangempela. Izinga lokushisa le-vulcanization le-polyethylene e-chlorine liyadingeka ukuthi lidlule ku-160 ℃ Ukukhiqizwa okuqhubekayo kungenziwa ngamanzi okupholisa, kodwa izinga lokushisa ngokuvamile alidluli ku-160 ℃. Ngakho-ke i-ejenti ye-vulcanizing esetshenziswa ku-polyethylene e-chlorine ayidingi ukungezwa ngokwehlukana nezinye izithasiselo, futhi ingaxutshwa ngqo nezinye izimpushana. Izidingo zokushisa zokuxuba ze-polyethylene e-chlorine zibanzi kakhulu, kusukela ku-40 ℃ kuya ku-120 ℃, futhi ngeke kube nokunamathela noma ukushiswa kwama-roller. Uma usebenzisa i-mixer evulekile, kuyadingeka ukuvala amanzi okupholisa noma ukuvula umusi ngesikhathi esifanele. Ngenxa yokuthi i-polyethylene e-chlorine ikhiqiza inani elikhulu lamandla okushisa ngenxa yokungqubuzana ngesikhathi sokuxuba, kubalulekile ukwengeza amanzi okupholisa anele lapho uxuba ku-mixer yangaphakathi. Izinga lokushisa lokukhipha ngokuvamile liphakathi kuka-110 ℃ no-120 ℃ Lokhu kuvumela inani elikhulu lomsebenzi wokuxuba oqhubekayo ngaphandle kokuphazamisa ikhwalithi ye-polyethylene ene-chlorine.
2. Indawo yokupaka kanye nokuhlanza okushisayo
Uma kuqhathaniswa nerabha ye-chloroprene, irabha exubile ye-polyethylene ene-chlorine inokuqina okungcono kokugcina futhi ayidingi ukugcinwa kokushisa okuphansi. Amazinga okushisa aphezulu ehlobo awaba nomthelela oqondile kuyo. I-polyethylene ene-chlorine ayidingi ukupholisa ngesikhathi sokuhlanza okushisayo, futhi izinga lokushisa lokuhlanza ngokuvamile lingaphezu kwama-50 ℃.
3. Ukwenza izimbobo zokuvikela izintambo nezintambo
I-polyethylene ene-chlorine ngokuvamile ingasetshenziswa ekukhiqizweni kwezintambo kanye nama-cable sheaths kusetshenziswa ama-long screw extruders noma ama-short screw extruders. Ngokuvamile, ama-wire kanye nama-cable sheaths enziwe ama-long screw extruders azokhanya, abushelelezi, futhi abe nezingxenye ezinemininingwane eminingi. Lapho ukhipha i-chlorine polyethylene anamathelayo, izinga lokushisa lekhanda ngokuvamile liphakathi kuka-6 ° C no-90 ° C. Ngenxa yokukhiqizwa kokushisa okukhulu ngesikhathi senqubo yokucwenga i-chlorine polyethylene, izinga lokushisa ngaphakathi kwezinto zerabha lizoba phezulu, ngokuvamile liphakathi kuka-90 ℃ no-120 ℃. Ngakho-ke, uma usebenzisa i-long screw extruder, kuyadingeka ukuqapha nokulawula izinga lokushisa eliyisisekelo ukuze ugweme ukusha kwezinto zerabha.
4. Inqubo yokwenza i-sulfurization
Uma kuqhathaniswa nezinye izinhlobo zezinto zerabha ezisetshenziswa kakhulu, isidingo sokushisa senqubo ye-vulcanization ye-polyethylene ene-chlorine siphezulu kakhulu, ngokuvamile siphakathi kuka-160 ℃ no-180 ℃ Izidingo ze-vulcanization ze-polyethylene wire kanye ne-cable sheath rubber yilezi:; Lapho ingcindezi yomusi ogcwele ingu-054 MPa, izinga lokushisa le-vulcanization lingu-160 ℃ kanti isikhathi se-vulcanization ngokuvamile siphakathi kwemizuzu engama-25 nemizuzu engama-30. Lapho ingcindezi yomusi ogcwele ingu-098MFRa, izinga lokushisa le-vulcanization lingu-180 ℃ kanti isikhathi se-vulcanization ngokuvamile siphakathi kwemizuzu engama-6mir-10. Lapho ingcindezi yomusi ogcwele ingu-152MPa, izinga lokushisa le-vulcanization lingu-200 ℃ kanti isikhathi se-vulcanization ngokuvamile siphakathi kwemizuzu eyi-1mir-3. Njengoba ingcindezi yomusi ogcwele ikhuphuka kancane kancane, izinga lokushisa le-vulcanization nalo liyanda kancane kancane, kuyilapho isikhathi se-vulcanization sincipha. Irabha ye-polyethylene ene-chlorine ephumelayo inokumelana okungcono kokudabuka.
