PVC foamed sheets, los yog Chevron laug cam thiab Andy boards, cov tshuaj sib xyaw ntawm polyvinyl chloride, yog li lawv kuj hu ua foamed polyvinyl chloride los xij. Siv sab nraud lub tsheb, tsheb nqaj hlau tsheb sab hauv tsev, txee sab hauv tsev, txee sab hauv tsev, sab hauv vaj huam sib luag sab nrauv, vaj tse sab nrauv, vaj tse sab hauv, kev txawb khoom, cov khoom siv ua si, cov khoom siv ua si, cov khoom siv aquaculture, cov khoom siv tsis haum, cov khoom tsis haum, cov khoom tsis haum, kos duab thiab ntau lub teeb nruab nrab ntawm iav ceilings.
Nyob rau hauv PVC foamed cov khoom, lub hom phiaj ntawm ntxiv ultra-siab molecular luj polymer yog raws li nram no: ib qho yog los txhawb lub plasticization ntawm PVC; ib qho yog los txhim kho lub zog ntawm PVC foaming khoom thiab tiv thaiv kev sib xyaw ua ke ntawm kev ua npuas kom tau ib yam khoom uas tsis zoo sib xws. Qhov thib peb yog los xyuas kom meej tias cov yaj tau zoo fluidity kom tau ib yam khoom nrog zoo tsos. Vim cov khoom sib txawv ntawm cov khoom foamed khoom sib txawv, cov khoom, cov txheej txheem, cov khoom siv raw thiab cov khoom siv lubrication siv sib txawv. Yog li ntawd, peb tau tsim foaming regulators nrog sib txawv zog kom tau raws li cov kev xav tau ntawm cov neeg siv.
