Kev ua tau zoo ntawm PVC hauv lub tshuab nqus tsev tsim

Yog li ntawd, rau qee qhov kev txhaj tshuaj molding (xws li txhaj tshuaj molding), nws yog ib qho tsim nyog los txo qhov hnyav molecular ntawm resin. Raws li qhov luaj li cas ntawm qhov hnyav molecular, domestic suspended polyvinyl chloride resin muab faib ua 1-7 qib, qhov loj dua tus lej, qhov me me ntawm qhov hnyav molecular. XJ-4 (XS-4) rau XJ-7 (XS-7) resins feem ntau yog siv rau hauv kev tsim cov kav dej tawv, tawv boards, thiab lwm yam. Lwm hom resins nrog qis molecular hnyav thiab siab dua molecular hnyav yuav tsum tau ntxiv ntau plasticization vim siab dua Tf Tus neeg saib xyuas txo Tf, yog li nws yog feem ntau siv nyob rau hauv kev tsim cov khoom muag muag. Polyvinyl chloride nrog qhov nruab nrab ntawm polymerization hauv qab 1000 yog hu ua qis degree ntawm polymerization polyvinyl chloride, uas muaj kev ua haujlwm zoo. Tsawg plasticizer tuaj yeem muab ntxiv thaum lub sijhawm ua haujlwm, yog li cov khoom lag luam yuav tsis nrawm dua vim kev tsiv teb tsaws ntawm plasticizer. Kev laus. Polyvinyl chloride cov khoom uas tsis tshua muaj qib ntawm polymerization muaj qhov pom zoo thiab tau siv dav hauv cov khoom siv hauv tsev, cov khoom ntim khoom noj thiab tshuaj thiab hloov pauv cov khoom plexiglass.
