Ukuxuba
Uma kuqhathaniswa nezinhlobo zendabuko zerabha ye-chloroprene. I-polyethylene e-chlorine ayidingi ukwenziwa ipulasitiki futhi ayidingi ukugcinwa ngemva kokwenziwa ipulasitiki. Izithasiselo zefomula ye-polyethylene e-chlorine zingaxutshwa futhi zimuncwe nezinye 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 ngaphansi kwesisekelo samanzi okupholisa, kodwa izinga lokushisa ngokuvamile alidluli ku-160 ℃. Ngakho-ke, i-ejenti ye-sulfurizing esetshenziswa ku-polyethylene e-chlorine akufanele ifakwe ngokwehlukana nezinye izithasiselo, futhi ingaxutshwa ngqo nezinye izimpushana. Izidingo zokushisa zokuxuba ze-polyethylene e-chlorine zibanzi kakhulu. Uma izinga lokushisa liphakathi kuka-40 ℃ no-120 ℃, ngeke kube khona ukunamathela noma ukushiswa kwama-roller. Uma usebenzisa i-mixer evulekile, kuyadingeka ukuvala amanzi okupholisa noma ukuvula umusi ngesikhathi esifanele. Ngenxa yokuthi i-polyethylene ene-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 ° C no-120 ° C Lokhu kuvumela inani elikhulu lomsebenzi wokuxuba oqhubekayo ngaphandle kokuphazamisa ikhwalithi ye-polyethylene ene-chlorine.
Ukugcina Nokucwengisisa Ukushisa
Uma kuqhathaniswa nerabha ye-fluoroprene, irabha exubile ye-polyethylene ene-chlorine inokuqina okungcono kokugcina futhi ayidingi ukugcinwa kokushisa okuphansi. Umswakama ophezulu ehlobo awunawo umthelela oqondile kuyo. I-polyethylene ene-chlorine ayidingi amanzi okupholisa ngesikhathi sokuhlanza okushisayo, futhi izinga lokushisa ngokuvamile kufanele libe ngaphezu kwama-50 ℃.
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 futhi aphelele. Lapho kukhishwa i-chlorine polyethylene anamathelayo, izinga lokushisa lekhanda ngokuvamile liphakathi kuka-6 ℃ no-90 ℃. 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.
Inqubo yokwenza i-sulfurization
Uma kuqhathaniswa nezinye izinhlobo zezinto zerabha ezisetshenziswa kakhulu, isidingo sokushisa senqubo ye-AC vulcanization ye-polyethylene e-chlorine siphezulu kakhulu, ngokuvamile siphakathi kuka-160 ℃ no-180 ℃ Izidingo ze-vulcanization ze-polyethylene wire chlorine kanye nerabha ye-cable sheath yilezi: lapho ingcindezi yayo yomhwamuko ogcwele ingu-054 MPa, izinga lokushisa le-vulcanization lingu-160 ℃, kanti isikhathi se-vulcanization ngokuvamile singu-25min-30min Lapho ingcindezi yomhwamuko ogcwele ingu-098MFRa, izinga lokushisa le-vulcanization lingu-180 ℃ kanti isikhathi se-vulcanization ngokuvamile singu-6mir-10 min. Lapho ingcindezi yomhwamuko ogcwele ingu-152MPa, izinga lokushisa le-vulcanization lingu-200 ℃ kanti isikhathi se-vulcanization ngokuvamile singu-1mir-3 min. Njengoba ingcindezi yomhwamuko ogcwele ikhuphuka kancane kancane, izinga lokushisa le-vulcanization nalo liyanda kancane kancane, kuyilapho isikhathi se-vulcanization sincipha. Irabha ye-polyethylene e-chlorine ephumelayo inamandla angcono okudonsa.
