PVC board hloov tau tiag tiag yog ib hom vinyl polymer. PVC yog ib qho ntawm cov khoom yas loj tshaj plaws hauv ntiaj teb.
Nws yog pheej yig thiab dav siv. PVC resin yog dawb los yog lub teeb daj hmoov PVC cov ntaub ntawv feem ntau ntxiv stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives in real use.
Cov khoom sib txawv tuaj yeem raug ntxiv raws li kev siv sib txawv, thiab PVC yas tuaj yeem qhia cov khoom sib txawv ntawm lub cev thiab cov khoom siv kho tshuab. Ntau yam khoom siv tawv, muag muag thiab pob tshab tuaj yeem tsim los ntawm kev ntxiv cov yas yas tsim nyog rau hauv PVC resin.
Cov yam ntxwv ntawm PVC saj zawg zog board khoom:
Nws muaj tsis muaj flammability, siab zog, huab cua tsis kam thiab zoo heev geometric stability. PVC flexible board muaj zog tiv thaiv oxidant, reductant thiab muaj zog acid. Txawm li cas los xij, nws tuaj yeem raug corroded los ntawm cov concentrated oxidizing acids xws li concentrated sulfuric acid thiab concentrated nitric acid, thiab nws tsis haum rau lub sij hawm nyob rau hauv kev sib cuag nrog aromatic hydrocarbons thiab chlorinated hydrocarbons.
Kev txhim kho ntawm cov ntaub ntawv yooj yim PVC board:
Raws li cov neeg siv khoom lag luam qis ntawm PVC lub rooj tsav xwm hloov pauv tau nthuav dav txhua xyoo, kev lag luam PVC hloov tau yooj yim tau ua rau muaj kev txhim kho ntau dua.
