(1) lub cev yas yas
Hom tshuaj plasticizer thiab polyvinyl chloride yog soluble, lawv cov miscibility piv yog 150: 100, tsis muaj phenomenon exudation.Commonly siv cov phthalate esters. Thaum tus naj npawb ntawm carbon atoms nyob rau hauv cawv yog hauv qab C8, lawv ntau soluble dua PVC resins. Yog hais tias carbon atoms muaj saum toj no C10, lawv muaj tsawg soluble thiab lawv cov yas yas tsis zoo. Txawm li cas los xij, hauv C4, sov poob, dej nqus dej thiab dej extraction.
Dibutyl phthalate (DBP) thiab dioctyl phthalate feem ntau siv hauv PVC daim ntaub nyias nyias. Dibutyl phthalate yog soluble nrog polyvinyl chloride cob, tab sis tsis taus, nrog kub kub thiab dej extraction.Qhov kev ua tau zoo ntawm dioctyl phthalate zoo, lub kub poob heev tsawg, thiab dej extraction yog heev me me.
(2) kev pabcuam yas
Muaj ob hom tshuaj plasticizers.One zoo yog cov khoom pov thawj yas, uas yog cov kua qaub dibasic acid, xws li sebacic acid dioctyl ester (DOS), adipic acid dioctyl ester, azelaic acid dioctyl ester cyanide ntau hom tshuaj sebacic acid dioctyl ester nyob rau hauv peb lub teb chaws, nws txias tsis zoo, thiab lubrication rau ib tug twg, tab sis nrog PVC cob intermiscibility yog pluag, yooj yim to taub, ntau tshaj 10 kev ua tau zoo yog tsis zoo, yog li ntawd ntau npaum li cas tsis muaj ntau, yog 8. lwm yog polyester plasticizer ( los yog polymer plasticizer), uas muaj lub luj loj loj thiab nws yog qhov tsis tshua muaj volatility.Feem ntau yog adipic acid, nonadipic acid, sebacic acid thiab monoethylene glycol synthesis ntawm cov tshuaj macromolecular.
(3) lwm hom phom
Muaj ntau ntau hom phomizers, xws li methyl alkyl sulfonate (m-50), epoxy ester, etc.Paraffin cresol ester ntawm alky sulfonate tau zoo dua tshwj tsis yog tias nws tsis qab txias, uas yuav siv tsis tau dioctyl phthalate.InIn Ntxiv rau yas zog, cov tshuaj epoxy kuj muaj stability.
