Njira yosungunula ya polyethylene ya chlorine

Mbali yosankha zosungunulira
Polyethylene yokhala ndi chlorine imasungunuka mu zosungunulira monga toluene kapena xylene. Kusungunuka kwa ester kumawonjezeka mwa kusungunulira ma ester monga butyl acetate kapena PMA (propylene glycol methyl ether acetate). Zosungunulira za polar monga methanol ndi ethanol zimathanso kuyanjana ndi maatomu a chlorine m'mamolekyu a polyethylene okhala ndi chlorine kuti zithandizire kusungunuka kwawo. Izi zili choncho chifukwa mamolekyu a polyethylene okhala ndi chlorine ali ndi maatomu a chlorine pa unyolo wawo, ndipo zosungunulira za polar zimatha kuyanjana bwino nazo.
Zinthu zina zomwe zimakhudza kuthetsedwa kwa ntchito ndi zina zokhudzana nazo
Mlingo wa chlorination: Mlingo wa chlorination wa polyethylene wothira chlorine ukakhala wokwera, kusungunuka kwake nthawi zambiri kumawonjezeka moyenerera, kotero polyethylene wothira chlorine wokhala ndi mlingo wothira chlorine wambiri ungakhale wosavuta kusungunuka.
Kutentha: Kawirikawiri, kutentha kukakwera, kusungunuka kwa polyethylene wothira chlorine mu solvent kumawonjezekanso. Kukweza kutentha kungathandize kufulumizitsa kusungunuka, chifukwa kutentha kwambiri kungathandize kuti unyolo wa polima usunthike, motero kufulumizitsa kuyanjana ndi solvents. Komabe, chitetezo chiyenera kuganiziridwa panthawi yogwira ntchito kuti tipewe ngozi monga kupsa (onani momwe kutentha kumakhudzira kusungunuka kwa zinthu zofanana za polima monga polyvinyl alcohol).
Kusakaniza (onani ntchito yosungunula zinthu zofanana): Ngakhale kuti ntchito yosakaniza panthawi yosungunuka kwa polyethylene yokhala ndi chlorine sinatchulidwe momveka bwino, malinga ndi kusungunuka kwa zinthu zofanana za polima, kusakaniza kumathandiza kulimbikitsa kusakaniza ndi zosungunulira, kuchepetsa kusiyana kwa kuchuluka kwa zinthu m'deralo, ndikufulumizitsa njira yosungunula. Mukawonjezera ufa wa polyethylene yokhala ndi chlorine ku chosungunulira, kusakaniza kumatha kuyambika nthawi imodzi kuti kulimbikitse kusungunuka.
Nthawi Yosungunula: Kuti polyethylene yokhala ndi chlorine isungunuke bwino, pamafunika nthawi yokwanira, monga momwe polyvinyl alcohol imafunira nthawi yokwanira kuti isungunuke. Komabe, nthawi yeniyeniyo ingafunike kudziwika kutengera zinthu zosiyanasiyana monga kuchuluka kwenikweni kwa polyethylene yokhala ndi chlorine, kuchuluka kwa zosungunulira, ndi kutentha.
