Lub luag haujlwm ntawm calcium zinc stabilizer

1. Muab kev ruaj khov thermal
Hauv cov txheej txheem ua yas, tshwj xeeb tshaj yog hauv kev tsim cov PVC, qhov kub siab tuaj yeem ua rau tawg thiab oxidation ntawm PVC molecular saw, yog li txo cov khoom siv lub cev thiab qhov zoo ntawm cov khoom. Calcium zinc stabilizers tuaj yeem nqus tau zoo thiab neutralize HCl, thaum hloov cov khoom siv nquag thiab tsis ruaj khov kom tiv thaiv kev sib cais ntawm HCl vim cua sov, yog li ua kom ntseeg tau tias kev ruaj khov ntawm PVC ntau lawm.
2. Muab kev ruaj khov ntawm photos
Cov hluav taws xob ultraviolet kuj yog ib qho tseem ceeb uas ua rau cov yas laus. Calcium zinc stabilizers tuaj yeem nqus cov hluav taws xob ultraviolet, txo qhov puas tsuaj ntawm cov hluav taws xob ultraviolet rau cov yas molecular saw, thiab yog li txhim kho qhov photostability ntawm cov yas.
3. Txhim kho qhov pom tseeb thiab lub zog xim
Cov tshuaj calcium zinc stabilizers muaj qhov pom tseeb zoo thiab muaj zog xim, uas tuaj yeem muab cov xim zoo li xav tau yam tsis cuam tshuam rau qhov pom tseeb ntawm cov khoom. Qhov no yog qhov tseem ceeb heev rau kev tsim cov khoom yas pob tshab zoo, xws li cov khoom ntim khoom noj, cov khoom siv kho mob, thiab lwm yam.
4. Kev ua tau zoo ntawm ib puag ncig
Piv rau cov ntsev lead cadmium thiab cov organotin stabilizers, cov calcium zinc stabilizers tsis muaj cov hlau hnyav thiab lwm yam khoom lom, ua rau lawv yog cov stabilizer zoo rau ib puag ncig. Qhov no ua rau nws siv dav hauv cov teb xws li kev ntim khoom noj thiab cov khoom siv kho mob.
5. Txhim kho kev sib raug zoo thiab kev sib kis tau zoo
Cov tshuaj calcium zinc stabilizers tuaj yeem txhim kho lawv qhov sib xws thiab kev sib kis nrog PVC resin, yog li ua kom cov khoom ua haujlwm zoo dua, txo cov khoom siv kho tshuab, thiab ntev lub neej ua haujlwm ntawm cov khoom siv. Tsis tas li ntawd, nws tuaj yeem muab cov khoom sib xyaw PVC nrog cov yas zoo sib xws thiab cov dej ntws ceev ceev, ua rau cov khoom du.
6. Kev tiv thaiv rau kev ua qias tuaj ntawm sulfurization
Cov tshuaj calcium zinc stabilizers muaj kev tiv thaiv zoo rau kev ua qias tuaj ntawm sulfurization thiab tuaj yeem tswj tau qhov ua tau zoo nyob rau hauv qhov kub siab yam tsis muaj kev ua qias tuaj ntawm sulfurization, uas yog qhov tseem ceeb rau kev tsim cov khoom yas zoo.
Hauv kev xaus, cov calcium zinc stabilizers ua lub luag haujlwm tseem ceeb hauv kev ua cov yas. Lawv tsis tsuas yog txhim kho qhov zoo thiab kev ua tau zoo ntawm cov khoom yas, tab sis kuj ua tau raws li qhov yuav tsum tau ua ntawm ib puag ncig. Lawv yog cov khoom siv ntxiv uas tsis tuaj yeem tsis quav ntsej hauv kev lag luam yas niaj hnub no.
