Ukuxuba
Xa kuthelekiswa neendlela zemveli zerabha ye-chloroprene. I-polyethylene ekhlorini ayifuni ukwenziwa iplastiki kwaye ayifuni kugcinwa emva kokwenziwa iplastiki. Izongezo zolwelo kwifomyula ye-polyethylene ekhlorini zinokuxutywa kwaye zifunxwe nezinye iipowders ngexesha lenkqubo yokuxuba, nto leyo enokuthintela ukucocwa nokuvuza ngexesha lenkqubo yokuxuba. Ubushushu be-vulcanization ye-polyethylene ekhlorini kufuneka budlule kwi-160 ℃ Imveliso eqhubekayo inokwenziwa phantsi kwesiseko samanzi okupholisa, kodwa ubushushu ngokubanzi abudluli kwi-160 ℃. Ke ngoko, i-arhente ye-sulfurizing esetyenziswa kwi-polyethylene ekhlorini akufuneki yongezwe ngokwahlukileyo kwezinye izongezo, kwaye ingaxutywa ngokuthe ngqo nezinye iipowders. Iimfuneko zobushushu bokuxuba kwi-polyethylene ekhlorini zibanzi. Xa ubushushu buphakathi kwe-40 ℃ ne-120 ℃, akuyi kubakho kunamathela okanye ukutsha kwee-rollers. Xa usebenzisa umxube ovulekileyo, kuyimfuneko ukucima amanzi okupholisa okanye ukuvula umphunga ngexesha elifanelekileyo. Ngenxa yokuba i-polyethylene enekhlorini ivelisa amandla amaninzi obushushu ngenxa yokungqubana ngexesha lokuxuba, kuyimfuneko ukongeza amanzi okupholisa aneleyo xa kuxuba kwi-mixer yangaphakathi. Ubushushu bokukhupha buhlala buphakathi kwe-110 ° C kunye ne-120 ° C Oku kuvumela ukuba kubekho umsebenzi omkhulu wokuxuba oqhubekayo ngaphandle kokuchaphazela kakubi umgangatho we-polyethylene enekhlorini.
Ukugcina kunye nokuCoca ubushushu
Xa kuthelekiswa nerabha ye-fluoroprene, irabha exutyiweyo ye-polyethylene ene-chlorine inozinzo olungcono lokugcina kwaye ayifuni kugcinwa kubushushu obuphantsi. Ukufuma okuphezulu ehlotyeni akunampembelelo ngqo kuyo. I-polyethylene ene-chlorine ayifuni manzi apholisayo ngexesha lokucocwa okushushu, kwaye ubushushu ngokubanzi kufuneka bube ngaphezulu kwama-50 ℃.
Ukwenza izikhonkwane zokukhusela iingcingo kunye neentambo
I-polyethylene ene-chlorine ngokubanzi ingasetyenziswa ekuveliseni ii-sheaths ze-wire kunye neentambo kusetyenziswa ii-extruders ezinde okanye ii-extruders ezimfutshane zezikrufu. Ngokubanzi, ii-sheaths ze-wire kunye neentambo ezenziwe zii-extruders ezinde zezikrufu ziya kuba zikhanya ngakumbi kwaye ziphelele. Xa kukhutshwa i-adhesive ye-polyethylene ene-chlorine, ubushushu bentloko ngokubanzi buphakathi kwe-6 ℃ kunye ne-90 ℃. Ngenxa yokuveliswa kobushushu obukhulu ngexesha lenkqubo yokucoca i-polyethylene ene-chlorine, ubushushu ngaphakathi kwezinto zerabha buya kuba phezulu, ngokubanzi buphakathi kwe-90 ℃ kunye ne-120 ℃. Ke ngoko, xa usebenzisa i-extruder ende yezikrufu, kuyimfuneko ukujonga nokulawula ubushushu obusisiseko ukuze kuthintelwe ukutsha kwezinto zerabha.
Inkqubo ye-sulfurization
Xa kuthelekiswa nezinye iintlobo zerabha ezisetyenziswa rhoqo, imfuneko yobushushu yenkqubo ye-AC vulcanization ye-polyethylene ekhlorini iphezulu, idla ngokuba phakathi kwe-160 ℃ ne-180 ℃ Iimfuneko ze-vulcanization ze-polyethylene wire kunye ne-cable sheath rubber zezi: xa uxinzelelo lwayo lomphunga olugcweleyo luyi-054 MPa, ubushushu be-vulcanization buyi-160 ℃, kwaye ixesha le-vulcanization lidla ngokuba yi-25min-30min Xa uxinzelelo lomphunga olugcweleyo luyi-098MFRa, ubushushu be-vulcanization buyi-180 ℃ kwaye ixesha le-vulcanization lidla ngokuba yi-6mir-10 min. Xa uxinzelelo lomphunga olugcweleyo luyi-152MPa, ubushushu be-vulcanization buyi-200 ℃ kwaye ixesha le-vulcanization lidla ngokuba yi-1mir-3 min. Njengoko uxinzelelo lomphunga olugcweleyo lukhula kancinci kancinci, ubushushu be-vulcanization buyanda kancinci kancinci, ngelixa ixesha le-vulcanization liyancipha. Irabha ye-polyethylene ekhloriniweyo ephumayo inamandla angcono okutyhala.
