Cov txheej txheem rau kev siv PVC foaming regulators yog dab tsi?

Hauv cov mis PVC ua npuas ncauj, txhawm rau kom tau txais cov khoom lag luam zoo sib xws, zoo, thiab ywj pheej, ntxiv rau kev siv cov khoom hloov pauv ua npuas ncauj xws li ACR cov khoom pab ua, cov khoom hloov pauv ua npuas ncauj PVC feem ntau kuj siv rau hauv cov mis. Qee zaum, cov khoom ua npuas ncauj xws li cov hlau oxides xws li zinc oxide thiab lead oxide, cov ntsev organic acid xws li zinc stearate, thiab urea derivatives kuj ntxiv (los kho qhov kub ntawm cov khoom ua npuas ncauj). Cov koob tshuaj ntawm cov khoom tswj kev ua npuas ncauj feem ntau yog 4% -8% (raws li tag nrho cov ntsiab lus resin), uas yuav tsum tau sib phim nrog cov neeg sawv cev ua npuas ncauj (xws li AC daj ua npuas ncauj, NC dawb ua npuas ncauj). Kev tsim cov phaj tuab xav tau kev nce ntxiv ntawm qhov sib piv ntawm cov neeg sawv cev ua npuas ncauj NC kub qis (qhov sib piv ib txwm ntawm 1.2 qhov NC + 0.5 qhov AC) kom tsis txhob muaj cov pa roj ntau dhau hauv theem tom qab ua rau ua npuas ncauj tawg; Kev tswj qhov ceev yuav tsum tau sib npaug ntawm cov roj tsim thiab qhov kub ntawm cov khoom ua npuas ncauj.
PVC foaming regulator yog ib qho polymer acrylate lotion. Nws muaj tag nrho cov yam ntxwv ntawm PVC ua cov khoom pab, tab sis nws qhov hnyav molecular siab dua li ntawm PVC ua cov khoom pab. Hauv cov txheej txheem PVC foaming, ntxiv PVC foaming regulator tuaj yeem ua rau lub zog yaj ntawm PVC cov khoom, yog li tiv thaiv kev sib xyaw ntawm cov npuas thiab tau txais cov khoom ua npuas PVC sib npaug. Tib lub sijhawm, nws kuj tseem tuaj yeem txhawb kev yas ntawm PVC thiab xyuas kom meej tias cov yaj muaj fluidity zoo.
Thaum xaiv cov khoom siv ua npuas dej PVC, yuav tsum tau them sai sai rau kev siv cov khoom siv ua npuas dej sib txawv rau PVC nrog ntau qib polymerization, xws li PVC-700, PVC-800, thiab PVC-1000. Cov khoom sib txawv, xws li cov laug cam ua npuas dej, cov laug cam tuab ua npuas dej, cov laug cam nyias ua npuas dej, cov laug cam ntoo yas ua npuas dej, cov laug cam ua npuas dej ua npuas dej, thiab lwm yam, yuav tsum tau siv cov khoom siv ua npuas dej sib txawv. Vim tias cov neeg sawv cev ua npuas dej PVC kuj yog cov khoom sib xyaw ua ke nrog cov khoom pab ua tiav, yuav tsum tau them sai sai rau qhov sib npaug ntawm lubrication sab hauv thiab sab nraud ntawm cov mis thaum siv lawv. Bangtai Petrochemical Foam Regulator ua tau raws li koj cov kev xav tau ntau yam rau cov khoom. Yog xav paub ntxiv txog cov khoom lag luam txog cov khoom siv ua npuas dej PVC, thov hu rau peb!
