Njira yopangira polyethylene yothira chlorine ya zingwe

Kusakaniza
Poyerekeza ndi mitundu yachikhalidwe ya rabara ya chloroprene. Polyethylene yokhala ndi chlorine siifuna kupangidwa pulasitiki ndipo siifuna kusungidwa pambuyo pa kupangidwa pulasitiki. Zowonjezera zamadzimadzi mu fomula ya polyethylene yokhala ndi chlorine zimatha kusakanikirana ndi kuyamwa ndi ufa wina panthawi yokonza, zomwe zingapewe kuyeretsa ndi kudontha madzi panthawi yosakaniza. Kutentha kwa vulcanization kwa polyethylene yokhala ndi chlorine kumafunika kupitirira 160 ℃ Kupanga kosalekeza kumatha kuchitika pansi pa madzi ozizira, koma kutentha nthawi zambiri sikupitirira 160 ℃. Chifukwa chake, sulfurizing agent yomwe imagwiritsidwa ntchito mu polyethylene yokhala ndi chlorine siyenera kuwonjezeredwa padera ndi zowonjezera zina, ndipo ikhoza kusakanikirana mwachindunji ndi ufa wina. Zofunikira kutentha kosakaniza kwa polyethylene yokhala ndi chlorine ndi zazikulu. Kutentha kukafika pakati pa 40 ℃ ndi 120 ℃, sipadzakhala kuuma kapena kuwotcha ma rollers. Mukamagwiritsa ntchito chosakanizira chotseguka, ndikofunikira kuzimitsa madzi ozizira kapena kuyatsa nthunzi nthawi yomweyo. Popeza polyethylene yokhala ndi chlorine imapanga mphamvu zambiri zotentha chifukwa cha kukangana panthawi yosakaniza, ndikofunikira kuwonjezera madzi ozizira okwanira posakaniza mu chosakanizira chamkati. Kutentha kwa kusakaniza nthawi zambiri kumakhala pakati pa 110 ° C ndi 120 ° C Izi zimathandiza kuti pakhale ntchito yambiri yosakaniza mosalekeza popanda kuwononga ubwino wa polyethylene yokhala ndi chlorine.
Kusungirako ndi Kuyeretsa Kutentha
Poyerekeza ndi rabala ya fluoroprene, rabala yosakaniza ya polyethylene yokhala ndi chlorine imakhala ndi kukhazikika bwino kosungira ndipo sikufuna kusungidwa kutentha kochepa. Chinyezi chambiri nthawi yachilimwe sichikhudza mwachindunji. Polyethylene yokhala ndi chlorine sikufuna madzi ozizira panthawi yoyeretsedwa ndi kutentha, ndipo kutentha kuyenera kukhala pamwamba pa 50 ℃.
Kupanga zipolopolo zoteteza mawaya ndi zingwe
Polyethylene yokhala ndi chlorine nthawi zambiri ingagwiritsidwe ntchito popanga ma waya ndi ma cable sheath pogwiritsa ntchito ma screw extruders aatali kapena ma short screw extruders. Kawirikawiri, ma waya ndi ma cable sheath opangidwa ndi ma screw extruders aatali adzakhala owala komanso odzaza. Mukatulutsa guluu wa polyethylene wokhala ndi chlorine, kutentha kwa mutu nthawi zambiri kumakhala pakati pa 6 ℃ ndi 90 ℃. Chifukwa cha kutentha kwakukulu komwe kumachitika panthawi yoyenga polyethylene yokhala ndi chlorine, kutentha mkati mwa zinthu za rabara kudzakhala kwakukulu, nthawi zambiri pakati pa 90 ℃ ndi 120 ℃. Chifukwa chake, mukagwiritsa ntchito screw extruder yayitali, ndikofunikira kuyang'anira ndikuwongolera kutentha koyambira kuti mupewe kuyaka kwa zinthu za rabala.
Njira yopangira sulfurization
Poyerekeza ndi mitundu ina ya zipangizo za rabara zomwe zimagwiritsidwa ntchito kwambiri, kutentha komwe kumafunika pa njira ya AC vulcanization ya polyethylene yokhala ndi chlorine kumakhala kokwera, nthawi zambiri pakati pa 160 ℃ ndi 180 ℃. Zofunikira pa vulcanization ya waya wa polyethylene wokhala ndi chlorinated ndi rabara ya chingwe ndi izi: pamene mphamvu yake ya nthunzi yokhuta ndi 054 MPa, kutentha kwa vulcanization ndi 160 ℃, ndipo nthawi ya vulcanization nthawi zambiri imakhala 25min-30min. Pamene mphamvu ya nthunzi yokhuta ndi 098MFRa, kutentha kwa vulcanization ndi 180 ℃ ndipo nthawi ya vulcanization nthawi zambiri imakhala 6mir-10 min. Pamene mphamvu ya nthunzi yokhuta ndi 152MPa, kutentha kwa vulcanization ndi 200 ℃ ndipo nthawi ya vulcanization nthawi zambiri imakhala 1mir-3 min. Pamene mphamvu ya nthunzi yokhuta imawonjezeka pang'onopang'ono, kutentha kwa vulcanization kumawonjezekanso pang'onopang'ono, pomwe nthawi ya vulcanization imachepa. Rabala ya polyethylene yokhala ndi chlorinated imakhala ndi mphamvu yokoka bwino.
