Dab tsi yog qhov txawv ntawm PU tawv thiab PVC tawv?

Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, kev tsim khoom siv tshuab thiab cov txheej txheem ntawm cov tawv hluavtaws tawv kuj tau txhim kho zoo heev nyob rau xyoo tas los no.Synthetic tawv cov ntaub ntawv yog ntau thiab ntau lug siv nyob rau hauv zus tau tej cov hnab, thiab PVC thiab PU hnab nyob rau hauv hluavtaws tawv yog nyiam los ntawm ntau cov neeg siv khoom!Tab sis raws li cov neeg siv khoom zoo tib yam, ntau tus neeg tsis paub qhov txawv ntawm PVC thiab PU,

1. Lub PU polyurethane txheej nyob rau hauv lub hnab yog muab faib ua PU dawb kua nplaum txheej thiab PU silver kua nplaum txheej.Cov yam ntxwv tseem ceeb ntawm PU dawb cov kua nplaum thiab cov kua nplaum nyiaj yog zoo ib yam li cov PA txheej, tab sis cov PU dawb cov kua nplaum thiab cov kua nplaum nplaum muaj lub ntsej muag puv tes, ntau cov ntaub elastic thiab zoo dua ceev ceev, thiab PU nyiaj nplaum txheej tuaj yeem tiv taus dej siab. siab, thiab PU txheej muaj noo noo permeability, qhov cua, hnav tsis kam, thiab lwm yam, tab sis tus nqi siab thiab huab cua tsis zoo.

2. Piv nrog PU txheej, cov ntaub hauv qab ntawm PVC txheej yog nyias thiab pheej yig dua.Txawm li cas los xij, zaj duab xis ntawm PVC txheej tsis yog tsuas yog lom, tab sis kuj yooj yim rau hnub nyoog.Qhov tseem ceeb tshaj, qhov kov ntawm PVC txheej tsis zoo li ntawm PU txheej, thiab cov ntaub kuj nyuaj.Yog tias koj siv hluav taws kub, qhov saj ntawm PVC txheej ntaub yog ntau dua li ntawm PU txheej ntaub.

3. Ntxiv rau qhov sib txawv ntawm PU thiab PVC coated fabrics hauv hnab hauv tes xav thiab saj, lwm qhov taw tes yog PU txheej feem ntau yog tawv, thaum PVC yog kua nplaum.

4. Cov txheej txheem tsim khoom ntawm PU tawv yog qhov nyuaj dua li ntawm PVC tawv.Raws li PU puag daim ntaub yog cov khoom siv PU canvas nrog lub zog tensile zoo, nws tuaj yeem coated rau saum cov ntaub hauv paus thiab tseem suav nrog hauv nruab nrab, ua rau nws tsis tuaj yeem pom qhov muaj nyob ntawm daim ntaub.

5. Lub cev muaj zog ntawm PU tawv zoo dua li cov tawv PVC, nrog kev ua haujlwm zoo rau flexure, softness, tensile zog thiab huab cua permeability (PVC tsis muaj).Cov qauv ntawm PVC tawv yog kub nias los ntawm steel qauv cov menyuam.Cov qauv ntawm PU tawv yog kub nias rau ntawm cov tawv nqaij semi-tiav nrog ib hom ntawv qauv.Tom qab txias, cov ntawv tawv yog sib cais rau saum npoo.Tus nqi ntawm PU tawv yog ntau tshaj ob npaug ntawm PVC tawv, thiab tus nqi ntawm PU tawv nrog tshwj xeeb yuav tsum yog 2-3 zaug siab dua li ntawm PVC tawv.Feem ntau, cov qauv ntawv yuav tsum tau siv rau PU tawv tsuas yog siv 4-5 zaug, thiab tom qab ntawd nws yuav muab pov tseg.Kev siv lub voj voog ntawm cov qauv rau cov menyuam yog ntev, yog li tus nqi ntawm PU tawv yog siab dua li ntawm PVC tawv.

Nyob rau hauv txoj kev no, tsuav yog peb nkag siab cov yam ntxwv ntawm ob, nws yuav yooj yim dua rau cov neeg siv khoom uas tsis yog cov kws tshaj lij los txheeb xyuas seb lub hnab puas yog PU lossis PVC, tsuav yog peb paub qhov txawv ntawm peb lub ntsiab lus hauv qab no: ua ntej, kev xav. yog mos thiab elastic, thaum xav tias tsis zoo thaum PVC yog tawv.Qhov thib ob, saib daim ntaub hauv qab.Cov ntaub hauv qab ntawm PU yog tuab dua thiab cov txheej yas yog nyias, thaum PVC yog nyias.Qhov thib peb yog kub.Pu saj yuav sib dua tom qab hlawv.

Raws li cov saum toj no, peb tseem tuaj yeem kos cov lus xaus: kuj hais lus, kev ua tau zoo ntawm PU tawv zoo dua li cov tawv PVC, thiab cov hnab PU zoo dua li cov hnab PVC!
