Nzira yekunyungudutsa chlorinated polyethylene

Chikamu chekusarudza solvent
Polyethylene ine chlorine inonyungudika muzvinhu zvinonyungudutsa zvakaita setoluene kana xylene. Kunyungudika kwe ester kunovandudzwa nekunyungudutsa ma esters akadai se butyl acetate kana PMA (propylene glycol methyl ether acetate). Zvinhu zvinonyungudutsa zvakaita se methanol ne ethanol zvinogonawo kushanda nemaatomu e chlorine mumamorekuru e polyethylene ane chlorine kuti zvikurudzire kunyungudika kwawo. Izvi zvinodaro nekuti mamorekuru e polyethylene ane chlorine ane maatomu e chlorine pamaketani awo, uye zvinonyungudutsa zvinogona kushanda zvakanaka nazvo.
Zvimwe zvinhu zvinokanganisa kuparadzwa kwemutemo pamwe nemabasa ane chekuita nazvo
Dhigirii reChlorination: Kana chlorination yepolyethylene ine chlorination yakakwira, kunyunguduka kwayo kunowanzowedzera zvichienderana, saka chlorinated polyethylene ine chlorination yakakwira inogona kunge iri nyore kunyunguduka.
Tembiricha: Kazhinji, tembiricha painowedzera, kunyungudika kwe chlorine polyethylene iri mumusanganiswa kunowedzerawo. Kukwidza tembiricha kunogona kubatsira kukurumidzisa mwero wekunyungudika, sezvo tembiricha yakakwira ichigona kukurudzira kufamba kwecheni dze polymer, nokudaro ichikurumidzisa kusangana nezvinonyungudika. Zvisinei, kuchengetedzeka kunofanirwa kufungwa nezvako panguva yekushanda kudzivirira tsaona dzakadai sekutsva (tarisa kukanganiswa kwetembiricha pakunyungudika kwezvinhu zvakafanana zve polymer zvakaita se polyvinyl alcohol).
Kukurunga (tarisa mashandiro ekunyungudutsa zvinhu zvakafanana): Kunyange hazvo basa rekukurunga panguva yekunyunguduka kwepolyethylene ine chlorine risingataurwi zvakajeka, kubva pakuona kwekunyunguduka kwezvinhu zvakafanana zvepolymer, kukurunga kunobatsira kukurudzira kusanganiswa nezvinyungudutsa, kuderedza mutsauko wehuwandu hwenzvimbo, uye kukurumidzisa maitiro ekunyunguduka. Kana uchiwedzera upfu hwepolyethylene ine chlorine kune solvent, kukurunga kunogona kutanga panguva imwe chete kukurudzira kunyunguduka.
Nguva yekunyungudika: Kuti ive nechokwadi chekuti polyethylene ine chlorine yanyungudika zvakakwana, nguva yakakwana inodiwa, sezvinoita polyvinyl alcohol inoda nguva yakakwana yekunyungudika. Zvisinei, nguva chaiyo ingangoda kutariswa zvichibva pazvinhu zvakasiyana-siyana zvakaita sehuwandu chaihwo hwepolyethylene ine chlorine, huwandu hwe solvent, uye tembiricha.
