Tsawg volatility, rub tawm tsis kam thiab tsis kam mus migration
B-22 thiab B-22D muaj phaus molecular txog 1000 li ntawm lub hnab yas rau PVC. Nws cov volatility yog 1/5 ntawm cov DOP, thiab nws qhov hnyav kuj tsis zoo dua li ntawm DOP. Tsis tas li ntawd, B-22 thiab B-22D muaj qhov tseem ceeb qis iodine thiab yog vim li no tiv taus migration.
Kev nyab xeeb huab cua tsis kam thiab kub kub
B-22 siv hauv PVC cov khoom, thiab nws siv nrog hlau stabilizers. Nws muaj Synergitism, uas ua rau cov huab cua ua haujlwm tsis zoo, ua kom sov thiab ua kom muaj cov pob zeb PVC. Nyob rau tib lub sijhawm, nws tuaj yeem txo tus nqi ntawm cov yas stabilizer thiab txo nqi.
Niaj hnub no, nrog kev paub txog kev tiv thaiv ib puag ncig, B-22 thiab Ca-Zn stabilizers yog cov uas tsis yog polluting thiab non-toxic formulations uas yuav hloov Cd-Ba-Zn lossis ua rau cov stabilizers. Nyob rau hauv cov nplaim hluav taws xob, kev sib ntxiv ntawm B-22 ua tau zoo zuj zus tuaj.
