Thaum lub sij hawm cov txheej txheem plasticization, calcium zinc stabilizers muaj lub siab electronegativity, thiab cov kab mob ntawm PVC resin muaj ib tug affinity, tsim muaj zog daim ntawv cog lus zog complexes.
Calcium zinc stabilizers tuaj yeem muab faib ua cov khoom calcium zinc stabilizers thiab kua calcium zinc stabilizers
Cov kua calcium zinc stabilizer yog sib xws nrog cov resins thiab plasticizers, nrog cov pob tshab zoo, tsis muaj nag lossis daus, tsawg npaum li cas, thiab siv tau yooj yim. Lub ntsiab tsis zoo yog lub lubrication tsis zoo thiab deterioration thaum lub sij hawm ntev cia.
Khoom calcium zinc stabilizers yog tsim los ntawm stearic acid xab npum. Cov khoom yog tus cwj pwm los ntawm lubricity zoo thiab yog tsim rau kev ua nyuaj PVC kav thiab profiles
Cov khoom lag luam ua tiav siv tshuab microemulsification kov yeej cov teeb meem uas tau hais tseg. Tsom ntsoov rau kev txhim kho los ntawm ob yam: hloov cov xim thawj zaug, siv cov zinc soap txaus, thiab siv cov khoom sib xyaw ua kom zinc chloride tsis muaj teeb meem, uas dhau los ua cov zinc complex; Txo tus nqi ntawm zinc xab npum los tiv thaiv cov zinc combustion thiab hloov cov xim pib nrog cov additives yog hu ua tsawg zinc blending. Nws tsis yog tsuas yog siv dav hauv cov khoom muag muag, tab sis kuj tseem nyob rau hauv kev ua cov khoom tawv.
Calcium zinc stabilizers, vim lawv cov electronegativity siab, muaj ib qho kev sib raug zoo rau cov kab mob ntawm PVC resin thaum lub sij hawm plasticization txheej txheem, tsim muaj zog daim ntawv cog lus zog complexes uas tsis muaj zog los yog daws cov attraction ntawm ion bonds nyob rau hauv ntau txheej ntawm PVC. Qhov no ua rau cov ntu sib txuas ntawm PVC yooj yim rau diffuse, thiab cov pab pawg molecular yog nyob rau thaj tsam me me, uas muaj txiaj ntsig zoo rau cov yas ntawm PVC resin. Ua rau muaj kev nce siab hauv melting siab, melting
Lub cev viscosity txo, qhov kub nce, thiab plasticizing kub txo.
Tsis tas li ntawd, raws li cov khoom siv hauv PVC yog tsim los rau kev siv cov hmoov lead ntsev stabilizers, txawm tias muaj cov roj nplua nyeem txaus ntxiv, nws tsis tuaj yeem tiv thaiv cov resin los ntawm kev ntxiv plasticizing nyob rau lub sijhawm txaus, cuam tshuam qhov qub lubrication tshuav. Nyob rau theem tom ntej ntawm kev siv, PVC yaj siv cov khoom siv hluav taws xob ntau hauv cov theem homogenization, tab sis tib lub sijhawm tsis tuaj yeem ua tiav qhov zoo tshaj plaws viscosity thiab elasticity kom tau raws li qhov xav tau ntawm PVC tawv.
