Cov txiaj ntsig thiab qhov tsis zoo ntawm cov calcium zinc stabilizers

Thaum lub sijhawm ua cov txheej txheem yas, cov calcium zinc stabilizers muaj lub zog electronegativity siab, thiab cov nodes ntawm PVC resin muaj qee qhov affinity, tsim cov khoom sib txuas muaj zog.
Calcium zinc stabilizers tuaj yeem muab faib ua cov khoom khov calcium zinc stabilizers thiab cov kua calcium zinc stabilizers.
Cov kua calcium zinc stabilizer yog sib xws nrog cov resins thiab plasticizers, nrog rau kev pom tseeb zoo, nag tsawg, koob tshuaj tsawg, thiab siv tau yooj yim. Qhov tsis zoo tseem ceeb yog qhov tsis muaj roj thiab puas tsuaj thaum khaws cia ntev.
Cov khoom ruaj khov calcium zinc feem ntau yog ua los ntawm xab npum stearic acid. Cov khoom no muaj lubricity zoo thiab tsim nyog rau kev ua cov kav dej PVC tawv thiab cov profile.
Cov khoom ua tiav los ntawm kev siv tshuab microemulsification kov yeej cov teeb meem uas tau hais los saum toj no. Ua kom pom tseeb rau kev txhim kho los ntawm ob qho: hloov cov xim pib, siv cov xab npum zinc txaus, thiab siv cov neeg sawv cev sib xyaw ua ke los ua kom zinc chloride tsis muaj teeb meem, uas dhau los ua cov zinc complex siab; Txo cov xab npum zinc kom tiv thaiv kev hlawv ntawm zinc thiab hloov cov xim pib nrog cov khoom ntxiv hu ua kev sib xyaw zinc qis. Nws tsis yog tsuas yog siv dav hauv cov khoom mos xwb, tab sis kuj tseem siv rau hauv kev ua cov khoom tawv.
Cov tshuaj calcium zinc stabilizers, vim lawv cov electronegativity siab, muaj qee qhov kev sib raug zoo rau cov nodes ntawm PVC resin thaum lub sijhawm ua kom yas, tsim cov khoom sib txuas muaj zog uas ua rau tsis muaj zog lossis daws qhov kev nyiam ntawm cov ion bonds 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 qhov yooj yim rau cov ciam teb me me, uas yog qhov zoo rau kev ua kom PVC resin. Ua rau muaj kev nce siab ntawm lub siab yaj, yaj
Lub cev viscosity txo qis, qhov kub nce ntxiv, thiab qhov kub ntawm plasticizing txo qis.
Tsis tas li ntawd xwb, vim tias cov khoom siv ua PVC ib txwm muaj rau kev ua cov tshuaj ua kom cov ntsev ua kom ruaj khov, txawm tias muaj cov roj nplua nyeem txaus ntxiv los xij, nws tsis tuaj yeem tiv thaiv cov roj hmab kom tsis txhob ua kom cov yas ntxiv rau lub sijhawm txaus, cuam tshuam rau qhov sib npaug ntawm cov roj nplua nyeem qub. Hauv theem tom qab ntawm kev siv, PVC yaj siv cov cua sov stabilizer ntau heev hauv theem homogenization, tab sis tib lub sijhawm tsis tuaj yeem ua tiav qhov viscosity thiab elasticity zoo tagnrho kom tau raws li qhov xav tau ntawm PVC tawv.
