1. Feem ntau siv cov ntaub ntawv rau cov khau tiv thaiv kev ruaj ntseg. Hnav cov khau los tiv thaiv zoo li qub yog ib qho ntawm txoj kev zoo thiab txhim khu kev qha rau kev tshem tawm hluav taws xob ntawm cov tswv. Vim tias cov tuam txhab tsim tawm, cov khau tiv thaiv zoo li niaj zaus tam sim no yuav tsum tsis txhob siv cov teeb meem qub los tiv thaiv, tiam sis kuj muaj cov khoom siv tsis muaj plua plav (dusting generated) uas yuav tsum tau ua rau cov neeg tawg mus nyob hauv chav tu chav.
Khoom siv sab saum toj: PVC tawv anti-static, PU tawv, canvas, ua npuas dej, thiab lwm yam.
Tib khoom: PVC tawv anti-static, PU tawv, lwm yam.
Cov hnab tawv ntoo av zoo li qub, khau tawv los tiv thaiv plaub-khawm, PU tawv tawv qub plaub tawv plaub-khau, nkawm khau av nkawm
2. Cov yam ntxwv ntawm PU khoom thiab cov khoom siv PVC: Lub zog muaj zog, nyias thiab elastic, mos thiab du, tsis muaj dej tsis huv; zoo tensile lub zog thiab tortuosity ntawm tsawg kub, zoo lub teeb ageing tsis kam thiab hydrolysis tiv thaiv kev sib deev; yooj, tsos thiab kev ua tau zoo nyob ze rau ntuj tawv, yooj yim ntxuav thiab decontaminate, yooj yim rau sew; tus nto du, yuav siv tau rau ntau hom kev kho mob thiab dyeing, ntau yam.
3, PU cov ntaub ntawv thiab cov khoom siv hauv PVC: kev tu dej thiab txhuam kom huv, tsis txhob txhuam cov roj; tsis tuaj yeem qhuav tu, tsuas yog dej ntxuav, pom zoo ntxuav qhov sov 40 ° C, zij kom sov li 50 ° C; tsis tuaj yeem raug rau tshav ntuj; tsis tuaj yeem kov ib co kua tshuaj organic, tsis txhob tshuaj dawb
4. Piv xam ntawm PU khau thiab PVC khau: Cov khoom siv PVC thiab PU yog cov khoom siv los ua cov khau tiv thaiv kab mob. Lub npe ntawm PVC yog "polyvinyl chloride", uas yog ib hom yas. Lub npe tag nrho ntawm PU yog "polyurethane", uas yog ib hom tawv hluavtaws. Muaj ntau qhov sib txawv ntawm ob, thiab cov khoom uas tau ua nrog rau ob cov ntaub ntawv kuj txawv ntawm qhov kev ua tau zoo.
