Isici sokukhetha isinyibilikisi
I-polyethylene ene-chlorine iyancibilika ezinyibilikisini ezifana ne-toluene noma i-xylene. Ukuncibilika kwe-ester kuthuthukiswa ngokuncibilikisa ama-ester afana ne-butyl acetate noma i-PMA (i-propylene glycol methyl ether acetate). Izinyibilikisi ze-polar ezifana ne-methanol ne-ethanol zingasebenzisana nama-athomu e-chlorine kuma-molecule e-polyethylene ane-chlorine ukuze kukhuthazwe ukuncibilika kwawo. Lokhu kungenxa yokuthi ama-molecule e-polyethylene ane-chlorine anama-athomu awo, futhi izinyibilikisi ze-polar zingasebenzisana kahle nawo.
Ezinye izinto ezithinta ukuqedwa kanye nemisebenzi ehlobene
Izinga lokufaka i-chlorine: Uma izinga lokufaka i-chlorine le-polyethylene ene-chlorine liphezulu, kulapho ukuncibilika kwayo kuvame ukwanda ngokufanele, ngakho-ke i-polyethylene ene-chlorine enezinga eliphezulu lokufaka i-chlorine ingaba lula ukuyincibilikisa.
Izinga Lokushisa: Ngokuvamile, njengoba izinga lokushisa likhuphuka, ukuncibilika kwe-polyethylene ene-chlorine ku-solvent nakho kuyanda. Ukuphakamisa izinga lokushisa kungasiza ekusheshiseni izinga lokuncibilika, njengoba amazinga okushisa aphezulu angakhuthaza ukunyakaza kwamaketanga e-polymer, ngaleyo ndlela kusheshiswe ukusebenzisana nezincibilikisi. Kodwa-ke, ukuphepha kufanele kucatshangelwe ngesikhathi sokusebenza ukuze kuvinjelwe izingozi ezifana nokusha (bheka ithonya lokushisa ekuncibilikeni kwezinto ezifanayo ze-polymer njenge-polyvinyl alcohol).
Ukuxuba (bheka ukusebenza lapho kuncibilikiswa izinto ezifanayo): Nakuba indima yokuxuba ngesikhathi kuncibilikiswa i-polyethylene ene-chlorine ingashiwongo ngokusobala, ngokombono wokuncibilikiswa kwezinto ezifanayo ze-polymer, ukuxuba kusiza ukukhuthaza ukuxubana nezinyibilikisi, ukunciphisa umehluko wokuhlushwa kwendawo, nokusheshisa inqubo yokuncibilikisa. Uma ufaka i-powder ye-polyethylene ene-chlorine ku-solvent, ukuxuba kungaqalwa ngesikhathi esisodwa ukukhuthaza ukuncibilika.
Isikhathi sokuncibilika: Ukuqinisekisa ukuncibilika okuphelele kwe-polyethylene ene-chlorine, kudingeka isikhathi esanele, njengoba nje i-polyvinyl alcohol idinga isikhathi esanele sokuncibilika. Kodwa-ke, isikhathi esithile kungadingeka sinqunywe ngokusekelwe ezicini ezahlukahlukene njengenani langempela le-polyethylene ene-chlorine, inani le-solvent, kanye nokushisa.
