Anti-impulse modifier: thaum ua cov yas, yog tias koj tsis ntxiv anti-impulse modifier, cov khoom tiav yas yuav dhau los ua nkig thiab tawv, me ntsis kov, yuav muaj kab nrib pleb, tsis tuaj yeem lav qhov zoo thiab kev pabcuam lub neej. Cov nyhuv ntawm impulse resistance modifier yog ua kom cov khoom yas tiv taus ntau dua rau qhov chaw sab nraud.
Impile-resistant modifiers feem ntau suav nrog cov pawg hauv qab no, suav nrog predetermined elastomer (PDE) impact modifier, unpredicted elastomer (NPDE) impact modifier, transitional impact modifier and mesh polymer modifier. Ntawm lawv, cov kev hloov pauv hloov pauv yog tsim los ntawm ob lub qauv, xws li ABS. Cov hom tshwj xeeb ntawm PVC cob siv yog:
(1) Chlorinated polyethylene (CPE): Siv HDPE hauv kev tshem tawm cov tshuaj chlorination nyob rau hauv cov dej theem, cov degree ntawm chlorination maj mam ua cov uncrystallized elastomer nrog nce chlorination. CPE siv raws li ib tug tougher feem ntau muaj Cl ntawm 25 feem pua -45 feem pua. Hauv PVC yeeb nkab thiab profile ntau lawm, feem ntau cov chaw tsim khoom siv CPE. Tus nqi ntxiv yog feem ntau yog 5-15 luam.
(2) ACR: nws yog qhov zoo tshaj plaws cuam tshuam kev hloov kho tau tsim nyob rau xyoo tas los no, uas tuaj yeem ua rau muaj kev cuam tshuam tsis zoo ntawm cov ntaub ntawv ntau ntau zaus. Haum rau kev siv sab nraum zoov PVC yas khoom cuam tshuam kev hloov kho, siv rau hauv PVC yas qhov rooj thiab qhov rais profile muaj kev ua tau zoo, du nto, zoo aging kuj, siab vuam lub kaum sab xis cov yam ntxwv, tab sis tus nqi yog hais txog 1 / 3 siab tshaj CPE.
(3) MBS: Qhov ntsuas qhov hnyav yog nyob nruab nrab ntawm 9.4 thiab 9.5, uas yog ze rau ntawm PVC, yog li nws muaj kev sib raug zoo nrog PVC. PVC tuaj yeem ua pob tshab. Feem ntau, ntxiv 10-17 cov qauv hauv PVC tuaj yeem ua rau muaj zog ntawm PVC los ntawm 6-15 zaug, tab sis thaum ntxiv MBS yog 30 daim ntawv, qhov cuam tshuam lub zog ntawm PVC txo qis dua. MBS tus nqi yog siab, feem ntau siv nrog EAV, CPE, S thiab lwm yam B S. MBS qhov kub tsis zoo, huab cua tsis zoo, tsis haum rau kev siv sab nraum zoov mus ntev rau cov khoom siv sab nraum zoov, feem ntau tsis tas yuav ua lub qhov rooj yas. thiab Windows profiles.
(4) ABS: nws yog siv los ua engineering plastics, tab sis kuj siv los ua PVC cuam tshuam kev hloov kho, thiab qhov kub thiab txias cuam tshuam kev hloov pauv kuj zoo heev. Thaum tus nqi ntawm ABS ntxiv mus txog 50 daim ntawv, qhov cuam tshuam lub zog ntawm PVC yog piv rau cov ntshiab ABS. Cov nyiaj ntxiv ntawm ABS feem ntau yog 5-20 qhov chaw, ABS huab cua tsis zoo, tsis haum rau kev siv sab nraum zoov mus sij hawm ntev ntawm cov khoom, feem ntau tsis tas yuav ua qhov cuam tshuam ntawm cov qhov rooj yas thiab Windows profile ntau lawm siv.
(5) EVA: thiab EVA thiab PVC refractive tus nqi sib txawv, nws yog ib qho nyuaj kom tau cov khoom pob tshab, feem ntau EVA yog siv nrog lwm yam cuam tshuam-resistant resin. EVA tau ntxiv hauv tsawg dua 10 daim ntawv luam.
