1. Fotokozani kufunika kwa kuchuluka kwa chlorine
Kuchuluka kwa klorini 24% -30%: koyenera kupanga zinthu zotanuka (monga zigawo zotetezera mawaya, matayala).
Kuchuluka kwa klorini 35% -38%: Kugwirizana bwino ndi PVC, komwe kumagwiritsidwa ntchito kwambiri posintha zinthu zolimba za PVC (monga zitseko ndi mawindo, mapaipi).
Kuchuluka kwa chlorine>40%: kungagwiritsidwe ntchito ngati pulasitiki kapena ngati chinthu choletsa dzimbiri komanso choletsa moto.
2. Yesani kulemera kwa mamolekyulu ndi mtundu wa zinthu zopangira
CPE yolemera kwambiri ya molekyulu: Ili ndi kukhuthala kwakukulu komanso mphamvu yokoka, zomwe zimachepetsa kumamatira kwake ku PVC.
CPE yolemera pang'ono ya molekyulu: kukhuthala kochepa, kuyenda bwino, koyenera zochitika zomwe zimafunikira magwiridwe antchito ambiri.
Chophimba cha polyethylene chochuluka kwambiri: Mtundu uwu wa CPE uli ndi kukana kutentha bwino ndipo ndi woyenera kugwiritsidwa ntchito m'malo otentha kwambiri.
3. Njira zopangira zinthu zikugwirizana ndi zofunikira pa ntchito
Ukadaulo wa mabulobu a chlorine: Ngati pakufunika kukonza magwiridwe antchito ndi kufanana kwa momwe chlorination reaction imagwirira ntchito (monga kufupikitsa nthawi yopangira), zinthu za CPE zomwe zimagwiritsa ntchito njira ya mabulobu a chlorine zitha kuyikidwa patsogolo.
Kugwiritsa ntchito thovu: Mukagwiritsa ntchito bolodi la thovu la PVC, ndikofunikira kuphatikiza chiŵerengero cha thovu (nthawi 2-3), kuchuluka (0.6-0.7 g/cm³), ndi kuuma kwa pamwamba kuti musankhe mitundu ya CPE yomwe imawonjezera mphamvu yosungunuka.
4. Kugwirizana ndi mgwirizano wogwira ntchito
Kugwirizana ndi PVC: CPE yokhala ndi chlorine ya 35% -38% imagwirizana bwino ndi PVC, zomwe zingathandize kukana kugwedezeka popanda kusokoneza kusinthasintha kwa ntchito.
Kukana mankhwala ndi kuletsa moto: CPE yokhala ndi chlorine wambiri (>50%) ndi yoyenera kugwiritsidwa ntchito polimbana ndi dzimbiri komanso zinthu zoletsa moto (monga mapaipi a mankhwala ndi zipangizo zomangira zosagwira moto).
5. Kuwongolera khalidwe ndi kuwunika kwa ogulitsa
Kufanana kwa tinthu tating'onoting'ono: Onetsetsani kuti kukula kwa tinthu ta CPE kukulamulidwa pakati pa 0.1-200 μ m kuti tipewe kusonkhana kapena kusasungunuka bwino chifukwa cha tinthu tating'onoting'ono.
Mtundu ndi Kuyesa: Sankhani ogulitsa omwe amapereka satifiketi yathunthu yaubwino (monga malipoti oyesa kuchuluka kwa chlorine, mayeso okhazikika pa kutentha), ndikuyika patsogolo kutsimikizira magwiridwe antchito azinthu zawo mu fomula yofunira (monga liwiro la pulasitiki, kufanana kwa maselo). Polyethylene ya chlorine ya Bontecn Group China imakupatsani ntchito ndi chitsimikizo chaubwino.
6. Kulinganiza mtengo ndi magwiridwe antchito
CPE Yonse: Zogulitsa zomwe zili ndi chlorine wochepa (35% -38%) zimakhala ndi mtengo wotsika ndipo zimatha kukwaniritsa zosowa zambiri zosinthira PVC.
Zochitika zapamwamba: Zofunikira zapadera zogwirira ntchito (monga thovu lochepa kwambiri komanso kukana kutentha kwambiri) zimafuna njira zosinthidwa, zomwe zingapangitse kuti ndalama ziwonjezeke.
Chidule: Kusankhidwa kwa CPE kuyenera kutengera zofunikira pakugwiritsa ntchito, kufananiza molondola zochitika zogwirira ntchito kudzera mu magawo monga kuchuluka kwa chlorine, kulemera kwa mamolekyulu, kuyanjana, ndi zina zotero, kuphatikiza ndi kutsimikizika kwa njira yopangira ndi kuwunika kwa ziyeneretso za ogulitsa, kuti pakhale mgwirizano wabwino pakati pa magwiridwe antchito ndi mtengo.
