Kusanganisa
Zvichienzaniswa nemarudzi echinyakare erabha rechloroprene. Polyethylene ine chlorine haidi purasitiki uye haidi kuchengetwa mushure mepurasitiki. Zvimwe zvinowedzera mufomura yepolyethylene ine chlorine zvinogona kusanganiswa nekunyudzwa nezvimwe upfu panguva yekubatanidza, izvo zvinogona kudzivirira kucheneswa nekudonha panguva yekusanganisa chaiko. Tembiricha ye vulcanization yepolyethylene ine chlorine inofanirwa kudarika 160 ℃ Kugadzirwa kunoramba kuripo kunogona kuitwa pasi pemvura inotonhorera, asi tembiricha kazhinji haipfuure 160 ℃. Saka, sulfurizing agent inoshandiswa mu polyethylene ine chlorine haifanirwe kuwedzerwa yakaparadzana nezvimwe zvinowedzera, uye inogona kusanganiswa zvakananga nezvimwe upfu. Zvinodiwa zvetembiricha yekusanganisa ye polyethylene ine chlorine zvakafara. Kana tembiricha iri pakati pe40 ℃ ne120 ℃, hapana kunamatira kana kupisa maroller. Paunenge uchishandisa 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 ° C ne120 ° C Izvi zvinobvumira huwandu hwakawanda hwebasa rekusanganisa risingaperi pasina kukanganisa kunaka kwepolyethylene ine chlorine.
Kuchengeta uye Kuchenesa Kupisa
Kana tichienzanisa nerabha yefluoroprene, rabha yakasanganiswa yepolyethylene ine chlorinated polyethylene ine kugadzikana kuri nani kwekuchengetwa uye haidi kuchengetwa patembiricha yakaderera. Hunyoro hwakawanda muzhizha hahuna simba rayo zvakananga. Polyethylene ine chlorinated haidi mvura inotonhorera panguva yekucheneswa kunopisa, uye tembiricha inofanira kunge iri pamusoro pe50 ℃.
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 dzakajeka uye dzakakwana. Pakuburitsa "chlorined polyethylene adhesive", tembiricha yemusoro inowanzova pakati pe6 ℃ ne90 ℃. 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.
Maitiro ekugadzira sulfurization
Zvichienzaniswa nedzimwe mhando dzerabha dzinoshandiswa zvakanyanya, tembiricha inodiwa pakushanda kweAC vulcanization ye chlorinated polyethylene yakanyanya, kazhinji pakati pe160 ℃ ne180 ℃. Zvinodiwa pakushanda kwe vulcanization ye chlorinated polyethylene waya uye cable sheath rabha ndeizvi: kana kumanikidzwa kwayo kwemhepo kwakazara kuri 054 MPa, tembiricha ye vulcanization iri 160 ℃, uye nguva ye vulcanization inowanzo kuve 25min-30min. Kana kumanikidzwa kwemhepo kwakazara kuri 098MFRa, tembiricha ye vulcanization iri 180 ℃ uye nguva ye vulcanization inowanzove 6mir-10 min. Kana kumanikidzwa kwemhepo kwakazara kuri 152MPa, tembiricha ye vulcanization iri 200 ℃ uye nguva ye vulcanization inowanzove 1mir-3 min. Sezvo kumanikidzwa kwemhepo kwakazara kuchiwedzera zvishoma nezvishoma, tembiricha ye vulcanization inowedzerawo zvishoma nezvishoma, nepo nguva ye vulcanization ichiderera. Rubha ye polyethylene ine chlorinated ine simba rekusimba riri nani.
