Maitiro ekugadzira sheath yepolyethylene ine chlorinated yewaya netambo:

1. Kusanganisa
Zvichienzaniswa nemarudzi echinyakare erabha rechloroprene. Polyethylene ine chlorine haidi purasitiki uye haidi kuchengetwa mushure mepurasitiki. Zvimwe zvinowedzerwa mumusanganiswa wepolyethylene ine chlorine zvinogona kusanganiswa nekunyudzwa kuburikidza nemamwe mapoda panguva yekubatanidza, izvo zvinogona kudzivirira kucheneswa nekudonha panguva yekusanganisa chaiko. Tembiricha ye vulcanization yepolyethylene ine chlorine inofanirwa kudarika 160 ℃ Kugadzirwa kunoramba kuripo kunogona kuitwa nemvura inotonhorera, asi tembiricha kazhinji haipfuure 160 ℃. Saka vulcanizing agent inoshandiswa mu polyethylene ine chlorine haidi kuwedzerwa zvakasiyana nezvimwe zvinowedzerwa, uye inogona kusanganiswa zvakananga nemamwe mapoda. Zvinodiwa zvekupisa zvekusanganisa polyethylene ine chlorine zvakakura, kubva pa40 ℃ kusvika 120 ℃, uye hapana kunamatira kana kupisa maroller. Paunoshandisa musanganiswa wakavhurika, zvakakosha kudzima mvura inotonhorera kana kubatidza utsi nenguva. Nekuti polyethylene ine chlorine inogadzira simba guru rekupisa nekuda kwekukweshana panguva yekusanganisa, zvakakosha kuwedzera mvura inotonhorera yakakwana pakusanganisa mumusanganiswa wemukati. Tembiricha yekugovera inowanzova pakati pe110 ℃ ne120 ℃ Izvi zvinobvumira huwandu hwakawanda hwebasa rekusanganisa risingaperi pasina kukanganisa kunaka kwepolyethylene ine chlorine.
2. Kupaka mota nekunatsa nzvimbo inopisa
Kana tichienzanisa nerabha rechloroprene, rabha rakasanganiswa repolyethylene rine chlorinated polyethylene rine kugadzikana kuri nani pakuchengetwa uye haridi kuchengetwa patembiricha yakaderera. Kupisa kwakanyanya muzhizha hakukanganisi zvakananga pairi. Polyethylene ine chlorinated haidi kutonhora panguva yekucheneswa kunopisa, uye tembiricha yekucheneswa inowanzo kuve pamusoro pe50 ℃.
3. Kugadzira matanda ekudzivirira waya netambo
Polyethylene ine chlorine inogona kushandiswa mukugadzira waya netambo dzemagetsi uchishandisa ma "long screw extruders" kana ma "short screw extruders". Kazhinji, waya netambo dzemagetsi dzinogadzirwa ne "long screw extruders" dzichava dzakapenya, dzakapfava, uye dzine zvikamu zvakawanda. Pakuburitsa "chlorined polyethylene adhesive", tembiricha yemusoro inowanzova pakati pe6 ° C ne90 ° C. Nekuda kwekupisa kwakanyanya panguva yekunatswa kwe "chlorined polyethylene", tembiricha iri mukati me "raber material" ichave yakakwira, kazhinji iri pakati pe90 ℃ ne120 ℃. Saka, kana uchishandisa "long screw extruder", zvakakosha kutarisa nekudzora tembiricha yepakutanga kuti isatsve zvinhu zverabha.
4. Maitiro ekugadzira sulfurization
Zvichienzaniswa nedzimwe mhando dzerabha dzinoshandiswa zvakanyanya, tembiricha inodiwa pakugadzira chlorine polyethylene yakakwira, kazhinji pakati pe160 ℃ ne180 ℃ Zvinodiwa pakugadzira chlorine polyethylene waya nerabha ye cable sheath ndeizvi: Kana kumanikidzwa kwemhepo kwakazara kuri 054 MPa, tembiricha yemhepo kwakazara iri 160 ℃ uye nguva yekuputika kazhinji iri pakati pemaminitsi makumi maviri nemashanu nemaminitsi makumi matatu. Kana kumanikidzwa kwemhepo kwakazara kuri 098MFRa, tembiricha yekuputika kwakazara iri 180 ℃ uye nguva yekuputika kazhinji iri pakati pemaminitsi matanhatu kusvika gumi. Kana kumanikidzwa kwemhepo kwakazara kuri 152MPa, tembiricha yekuputika kwakazara iri 200 ℃ uye nguva yekuputika kazhinji iri pakati pemaminitsi gumi nematatu. Sezvo kumanikidzwa kwemhepo kwakazara kuchiwedzera zvishoma nezvishoma, tembiricha yekuputika kwakawedzerawo zvishoma nezvishoma, nepo nguva yekuputika kwakazara ichiderera. Rubha yepolyethylene yakakonzerwa nechlorine ine resistance iri nani yekubvarura.
