Dab tsi yog cov haujlwm ntawm PVC kev pab cuam?

1. PVC ua cov khoom siv PA-20 thiab PA-40, raws li cov khoom siv ACR tuaj txawv teb chaws, tau siv dav hauv PVC pob tshab zaj duab xis, PVC ntawv, PVC hais, PVC hoses thiab lwm yam khoom siv los txhim kho qhov sib txawv thiab thermal ua haujlwm ntawm PVC sib tov, nto ci ntsa iab, zoo txo ​​cov khoom pov tseg, thiab daws cov teeb meem ntawm cov cim ntws thiab cov ntsiab lus siv lead ua uas nquag tshwm sim hauv kev tsim khoom.
Vim nws qhov hnyav molecular ultra-siab, PA-40 yog dav siv los ua foaming regulator nyob rau hauv PVC ua npuas ncauj boards, PVC ua npuas ncauj kav, thiab lwm yam khoom, uas ua rau uniform foaming thiab cov khoom zoo.
2. Impact modifier MBS Impact resistant MBS resin feem ntau yog siv rau hauv PVC ua thiab tsim cov txheej txheem los txhim kho nws qhov cuam tshuam lub zog yam tsis muaj kev puas tsuaj rau cov yam ntxwv ntawm PVC.Vim nws qhov zoo sib xws ntawm cov dej tsis sib haum rau PVC, ob qho tib si muaj qhov zoo thermodynamic sib raug zoo, uas muaj kev cuam tshuam lub zog, kub tsis kam, thiab xim xim ntawm PVC ntawm chav tsev lossis qhov kub thiab txias.Transparent modifier MBS Transparent MBS resin feem ntau yog siv rau hauv kev ua thiab tsim cov khoom pob tshab PVC, txhim kho lawv cov kev cuam tshuam lub zog yam tsis muaj kev puas tsuaj rau cov yam ntxwv ntawm cov khoom pob tshab PVC.Nws qhov refractive index zoo ib yam li PVC, thiab siv MBS raws li PVC cuam tshuam kev hloov pauv yuav tsis cuam tshuam rau cov pob tshab ntawm PVC.Nws yog cov khoom siv zoo tshaj plaws rau kev txhim kho PVC cuam tshuam thiab tsim cov khoom pob tshab.Piv nrog rau lwm lub tuam txhab, peb MBS muaj kev cuam tshuam ntau dua, kev sib raug zoo zoo dua, thiab hnav tsis kam MBS enhancer BLD-81 (kev hloov pauv, tsom rau PVC kav thiab fittings) yog siv los txhim kho lub zog thiab huab cua tsis kam ntawm PVC profile khoom.
