1. 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 zinokuvuthululwa kwaye zifunxwe ngezinye 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 ngamanzi okupholisa, kodwa ubushushu ngokubanzi abudluli kwi-160 ℃. Ngoko ke i-agent ye-vulcanizing esetyenziswa kwi-polyethylene ekhlorini akufuneki yongezwe ngokwahlukileyo kwezinye izongezo, kwaye ingaxutywa ngokuthe ngqo nezinye iipowders. Iimfuneko zobushushu bokuxuba kwi-polyethylene ekhlorini zibanzi, ukusuka kwi-40 ℃ ukuya kwi-120 ℃, kwaye akuyi kubakho kunamathela okanye ukutsha kweeroli. Xa usebenzisa umxube ovulekileyo, kuyimfuneko ukucima amanzi okupholisa okanye ukuvula umphunga ngexesha elifanelekileyo. Ngenxa yokuba i-polyethylene ekhlorini ivelisa amandla amaninzi obushushu ngenxa yokungqubana ngexesha lokuxuba, kuyimfuneko ukongeza amanzi okupholisa aneleyo xa uxuba kumxube wangaphakathi. Ubushushu bokukhupha amanzi ngokubanzi buphakathi kwe-110 ℃ kunye ne-120 ℃ Oku kuvumela ukuba kubekho umsebenzi omkhulu wokuxuba oqhubekayo ngaphandle kokuchaphazela kakubi umgangatho we-polyethylene ekhlorini.
2. Ukupaka kunye nokucocwa okushushu
Xa kuthelekiswa nerabha ye-chloroprene, irabha exutyiweyo ye-polyethylene ene-chlorine inozinzo olungcono lokugcina kwaye ayifuni kugcinwa kubushushu obuphantsi. Amaqondo obushushu aphezulu ehlotyeni awayichaphazeli ngqo. I-polyethylene ene-chlorine ayifuni kupholisa ngexesha lokucoca okushushu, kwaye amaqondo obushushu okucoca ngokubanzi angaphezulu kwama-50 ℃.
3. 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, zigudile, kwaye zibe namacandelo aneenkcukacha ezithe kratya. Xa kukhutshwa i-adhesive ye-polyethylene ene-chlorine, ubushushu bentloko ngokubanzi buphakathi kwe-6 ° C kunye ne-90 ° C. 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 kusetyenziswa i-extruder ende yezikrufu, kuyimfuneko ukujonga nokulawula ubushushu obusisiseko ukuze kuthintelwe ukutsha kwezinto zerabha.
4. Inkqubo ye-Sulfurization
Xa kuthelekiswa nezinye iintlobo zerabha ezisetyenziswa rhoqo, imfuneko yobushushu kwinkqubo ye-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 lomphunga olugcweleyo luyi-054 MPa, ubushushu be-vulcanization buyi-160 ℃ kwaye ixesha le-vulcanization liqhele ukuba phakathi kwe-25min kunye ne-30min. Xa uxinzelelo lomphunga olugcweleyo luyi-098MFRa, ubushushu be-vulcanization buyi-180 ℃ kwaye ixesha le-vulcanization liqhele ukuba phakathi kwe-6mir-10 min. Xa uxinzelelo lomphunga olugcweleyo luyi-152MPa, ubushushu be-vulcanization buyi-200 ℃ kwaye ixesha le-vulcanization liqhele ukuba phakathi kwe-1mir-3 min. Njengoko uxinzelelo lomphunga olugcweleyo lukhula kancinci kancinci, ubushushu be-vulcanization buyanda kancinci kancinci, ngelixa ixesha le-vulcanization liyancipha. Irabha ye-polyethylene ekhlorini ephumayo inokumelana ngcono nokukrazula.
