Vim li cas PVC thiaj xav tau cua sov Stabilizers?

PVC stabilizer yog ib qho tseem ceeb ntxiv rau PVC resin los ua cov yas nrog cov nqi siv tau. Thaum tshav kub kub nce mus txog 90, ntshiab PVC cob yog rhiab heev rau cua sov. Yog tias qhov kub siab tshaj C, me ntsis thermal decomposition yuav tshwm sim. Thaum qhov kub nce mus txog 120 degree, qhov tshwm sim ntawm thermal decomposition tshwm sim. Lub thermal decomposition mechanism ntawm PVC yog heev complex, tab sis cov ntsiab lus ntawm thermal decomposition cov tshuaj tiv thaiv ntawm PVC yog ib tug series ntawm cov tshuaj tiv thaiv los ntawm HCL tshem tawm cov tshuaj tiv thaiv. Tom qab Z, cov saw hlau macromolecular tawg, ua rau tsis ua haujlwm ntawm PVC cob. Ntxiv cov cua sov stabilizer yog ib txoj hauv kev zoo los txhim kho cov thermal stability ntawm PVC.
