Nyob rau lub sijhawm tsis ntev los no, ntau cov ntaub ntawv tshiab tau tshwm sim, yog li cov khoom uas muaj tus nqi siab dua yav dhau los tau maj mam hloov ntawm tus nqi, tshwj xeeb tshaj yog hauv cov khau thiab cov kav dej.
?
Tau kawg, qee cov ntaub ntawv zoo li muaj qhov zoo. Tom qab kev tshawb nrhiav, koj tuaj yeem nkag siab tias qee yam ntawm cov xwm txheej yog dab tsi.
?
Piv txwv li, ob cov ntaub ntawv ntawm pvc thiab pu, ntau tus neeg yeej ib txwm muaj kev tsis ntseeg, yog li qhov txawv ntawm pvc thiab pu cov ntaub ntawv?
?
Qhov sib txawv ntawm cov khoom siv pvc thiab pu
?
PU tawv yog qhov nyuaj dua li PVC tawv hauv kev tsim khoom. Vim tias PU puag ntaub yog cov ntaub ntawv PU cov ntaub ntawv uas muaj lub zog tensile zoo, ntxiv rau kev coated rau saum cov ntaub, lub hauv paus ntaub kuj tseem tuaj yeem muab tso rau hauv nruab nrab kom nws zoo li tsis tuaj yeem pom lub neej ntawm daim ntaub.
?
1. Lub cev muaj zog ntawm PU tawv yog zoo dua li PVC tawv, resistant rau tortuosity, softness, siab tensile zog, thiab breathable (tsis muaj PVC).
?
Cov qauv ntawm PVC tawv yog tsim los ntawm kub nias ntawm steel qauv rollers. Cov qauv ntawm PU tawv yog kub nias rau ntawm cov tawv nqaij semi-tiav nrog ib hom ntawv qauv. Tom qab tos kom txias, daim ntawv tawv yog sib cais thiab kho qhov chaw.
?
Tus nqi ntawm PU yog ntau dua ob npaug ntawm PVC, thiab tus nqi ntawm PU tawv nrog qee qhov tshwj xeeb yuav tsum yog 2-3 npaug siab dua li ntawm PVC tawv.
?
Feem ntau, cov qauv ntawv xav tau rau PU tawv tsuas yog muab pov tseg tom qab 4-5 zaug. Lub sij hawm siv ntawm cov qauv cov menyuam yog ntev, yog li tus nqi ntawm PU tawv yog siab dua li ntawm PVC tawv.
?
2. Txoj kev sib txawv ntawm PU thiab PVC yog qhov yooj yim.
?
Los ntawm cov ces kaum, lub hauv paus ntaub ntawm PU yog tuab dua li PVC. Kuj muaj qhov txawv ntawm qhov xav. Qhov kev xav ntawm PU yog softer. PVC xav tias nyuaj.
?
Koj tseem tuaj yeem siv hluav taws kub hnyiab, qhov saj ntawm PU yog sib dua li ntawm PVC.
