Inkalo yokukhetha isinyibilikisi
I-polyethylene ekhlorini iyanyibilika kwizinyibilikisi ezifana ne-toluene okanye i-xylene. Ukunyibilika kwe-ester kuphucuka ngokunyibilikisa ii-esters ezifana ne-butyl acetate okanye i-PMA (i-propylene glycol methyl ether acetate). Izinyibilikisi ze-polar ezifana ne-methanol kunye ne-ethanol zinokusebenzisana nee-athomu ze-chlorine kwiimolekyuli ze-polyethylene ezikhlorini ukukhuthaza ukunyibilika kwazo. Oku kungenxa yokuba iimolekyuli ze-polyethylene ezikhlorini zinee-athomu ze-chlorine kwiitsheyini zazo, kwaye izinyibilikisi ze-polar zinokusebenzisana kakuhle nazo.
Ezinye izinto ezichaphazela ukuchithwa kunye nemisebenzi enxulumene noko
Inqanaba le-chlorination: Okukhona inqanaba le-chlorination ye-polyethylene ekhlorini iphezulu, kokukhona ukunyibilika kwayo kudla ngokwanda ngokufanelekileyo, ngoko ke i-polyethylene ekhlorini enezinga eliphezulu le-chlorination inokuba lula ukuyinyibilikisa.
Ubushushu: Ngokubanzi, njengoko ubushushu busanda, ukunyibilika kwe-polyethylene ekhlorini kwi-solvent nako kuyanda. Ukunyusa ubushushu kunokunceda ukukhawulezisa izinga lokunyibilika, njengoko ubushushu obuphezulu bunokukhuthaza ukuhamba kweetyathanga ze-polymer, ngaloo ndlela kukhawuleziswe ukusebenzisana nezinyibilikisi. Nangona kunjalo, ukhuseleko kufuneka luqwalaselwe ngexesha lokusebenza ukuthintela iingozi ezifana nokutsha (bhekisa kwimpembelelo yobushushu ekunyibilikeni kwezinto ezifanayo ze-polymer ezifana ne-polyvinyl alcohol).
Ukuxuba (jonga umsebenzi xa kunyibilikiswa izinto ezifanayo): Nangona indima yokuxuba ngexesha lokunyibilika kwe-polyethylene ekhlorini ingakhankanywanga ngokucacileyo, ngokwembono yokunyibilika kwezinto ezifanayo ze-polymer, ukuxuba kunceda ukukhuthaza ukuxubana nezinyibilikisi, ukunciphisa umahluko woxinzelelo lwendawo, kunye nokukhawulezisa inkqubo yokunyibilika. Xa ukongeza umgubo we-polyethylene ekhlorini kwisinyibilikisi, ukuxuba kunokuqaliswa ngaxeshanye ukukhuthaza ukunyibilika.
Ixesha lokunyibilika: Ukuqinisekisa ukunyibilika ngokupheleleyo kwe-polyethylene ene-chlorine, kufuneka ixesha elaneleyo, kanye njengokuba i-polyvinyl alcohol ifuna ixesha elaneleyo lokunyibilika. Nangona kunjalo, ixesha elithile linokufuneka limiselwe ngokusekelwe kwizinto ezahlukeneyo ezifana nobungakanani bokwenyani be-polyethylene ene-chlorine, ubungakanani besinyibilikisi, kunye nobushushu.
