Kev faib tawm thiab kev xaiv ntawm PVC modifiers

Cov khoom siv hloov kho PVC yog siv los ua cov khoom hloov kho rau cov iav amorphous PVC raws li lawv cov haujlwm thiab cov yam ntxwv hloov kho, thiab tuaj yeem faib ua:
① Cov khoom hloov kho qhov cuam tshuam: siv rau hauv cov khoom sib xyaw uas tsis pom tseeb.
② Kev hloov kho pob tshab: Qhov kev hloov kho no yog siv thaum xav tau cov khoom siv kho qhov muag thiab kev cuam tshuam.
③Heat deformation modifier: siv los txhim kho qhov kub ntawm PVC sib tov.
④ Cov khoom hloov kho ib txwm muaj: siv los txhim kho kev tiv thaiv kev cuam tshuam, lub zog kub siab thiab kev hloov pauv kub qis.
⑤Huab cua tsis kam hloov kho: Hom kev hloov kho no tuaj yeem siv rau hauv cov ntawv thov sab nraum zoov kom tiv thaiv kev puas tsuaj ntawm ultraviolet photodegradation.
⑥Cov khoom pab ua tiav: Txhim kho kev ua haujlwm yaj ntawm PVC los ntawm kev txo lub sijhawm yaj.

Cov khoom siv hloov kho kom zoo dua qub—DP300 yog cov khoom siv ntxiv rau cov khoom yas mos thiab cov khoom yas ib nrab mos. Nws cov yam ntxwv: txhim kho kev ua haujlwm ntawm cov khoom PVC, kev ua kom zoo thiab kev ntws ntawm PVC; kho tau Qhov sib xws ntawm cov hlwb ua npuas ncauj txo qhov tsim cov qhov ua npuas ncauj thiab qhov perforations; txhim kho lub zog tensile, lub zog tensile thiab lub zog rhuav tshem ntawm cov khoom PVC; nws tuaj yeem ua rau kom muaj ntau cov khoom siv ntxiv.

MDNR)-4OPVC yog ib hom polymer amphiphilic hyperbranched, uas siv tau rau hauv cov khoom PVC los txhim kho qhov tsis kam khawb thiab tsis kam pleev xim ntawm qhov chaw ntawm cov khoom PVC, thiab muaj cov khoom tiv thaiv zoo li qub. MDNR-40PVC yuav tsis txav mus los lossis poob rau hauv cov ntaub ntawv PVC, thiab tsis muaj kev cuam tshuam rau kev pleev xim, luam ntawv, electroplating, thiab lwm yam. MDNR-4OPVC yog qhov tsim nyog rau cov ntaub ntawv PVC pob tshab, uas tuaj yeem txhim kho qhov tsis kam khawb thiab kov tsis kam ntawm qhov chaw ntawm cov khoom, thiab tseem tuaj yeem txhim kho qhov pob tshab thiab qhov ci ntawm PVC.

SP-1800 hyperdispersant yog ib hom PVC mos thiab tawv PVC tshwj xeeb-puab cov khoom siv, PVC yeeb nkab, PVC yeeb nkab hluav taws xob, PVC daim ntawv, PVC tawv hauv pem teb, PVC hlau thiab cable, PVC tawv dag, PVC daim ntawv, PVC phab ntsa ntawv, PVC khau khoom, thiab lwm yam. Cov khoom tsim rau cov khoom. SP-1800 hyperdispersant ua kom yooj yim cov mis thiab cov txheej txheem ua cov khoom PVC. Hauv cov khoom PVC, nws yog qhov tsim nyog los xaiv hom calcium carbonate (calcium carbonate sib dua thiab calcium carbonate hnyav), nrog rau qhov zoo thiab dawb ntawm calcium carbonate. , tsis xav txog qhov cuam tshuam ntawm PVC ua tsis ruaj khov thiab kev hloov pauv xim sib txawv los ntawm calcium carbonate cov tuam txhab tsim khoom xaiv cov neeg sawv cev sib txawv thiab cov txheej txheem kho. SP-1800 txhim kho cov khoom siv kho tshuab ntawm cov khoom PVC, thiab tseem tuaj yeem ua rau kom muaj ntau ntxiv ntawm cov hmoov inorganic.
