1, Kev tiv thaiv kev sib ntswg thiab tig: zoo heev li tawv nqaij ntuj, tsis muaj kab nrib pleb hauv 200,000 zaug sib ntswg ntawm qhov kub ib txwm, 30,000 zaug tsis muaj kab nrib pleb ntawm -20 ℃.
2, Feem pua ntawm kev nthuav dav (tawv zoo kov)
3, Lub zog tsim kua muag thiab tev tawv (Kev hnav siab / tsim kua muag tsis kam / lub zog tensile muaj zog)
4, Tsis txhob ua rau muaj kuab paug los ntawm kev tsim khoom mus rau kev siv, ib puag ncig tus phooj ywg.
Cov microfibers zoo li tawv tiag tiag. Txawm hais tias qhov tuab sib xws, lub zog rhuav, xim nplua nuj, kev siv cov ntaub ntawv zoo dua li tawv tiag tiag, yog qhov sib txawv ntawm cov tawv hluavtaws yav tom ntej. Koj tuaj yeem siv roj av zoo lossis dej ntshiab los ntxuav nws yog tias muaj qhov qias neeg ntawm qhov chaw ntawm mifrofiber, tab sis txwv tsis pub ntxuav nws nrog cov kuab tshuaj organic lossis txhua yam uas muaj alkaline uas yuav cuam tshuam rau qhov zoo. Cov xwm txheej siv: Tsis pub ntau tshaj 25 feeb thaum lub sijhawm kub 100 ℃, 10 feeb ntawm 120 ℃, 5 feeb ntawm 130 ℃.
Vim nws cov yam ntxwv zoo heev ntawm ntuj, nws siv dav hauv kev tsim cov khoom siv niaj hnub thiab cov khoom lag luam. Txawm li cas los xij, thaum cov pej xeem hauv ntiaj teb loj hlob tuaj, tib neeg xav tau tawv tau ob npaug, thiab cov tawv ntuj tsawg tsawg tau ntev tsis tuaj yeem ua tau raws li tib neeg xav tau. Txhawm rau daws qhov kev tsis sib haum xeeb no, cov kws tshawb fawb tau pib tshawb fawb thiab tsim cov tawv cuav thiab tawv hluavtaws ntau xyoo dhau los los ua kom tiav qhov tsis zoo ntawm cov tawv ntuj. Cov txheej txheem keeb kwm ntawm ntau tshaj 50 xyoo ntawm kev tshawb fawb yog cov txheej txheem ntawm cov tawv cuav thiab tawv hluavtaws sib tw cov tawv ntuj.
Cov kws tshawb fawb tau pib los ntawm kev tshawb fawb thiab kev txheeb xyuas cov tshuaj lom neeg thiab cov qauv ntawm cov tawv nqaij ntuj, pib nrog cov ntaub nitrocellulose varnished, thiab nkag mus rau PVC tawv nqaij cuav, uas yog thawj tiam ntawm cov tawv nqaij cuav. Ntawm lub hauv paus no, cov kws tshawb fawb tau ua ntau yam kev txhim kho thiab kev tshawb nrhiav, thawj zaug kev txhim kho ntawm lub substrate, thiab tom qab ntawd kev hloov kho thiab kev txhim kho ntawm cov txheej txheem resin. Xyoo 1970, cov ntaub ua los ntawm cov fiber tsis-woven tau raug punched rau hauv cov nets, bonded rau hauv cov nets, thiab lwm yam, yog li cov khoom siv hauv paus muaj ib feem zoo li lotus, cov duab fiber hollow, thiab mus txog qhov porous qauv, uas yog nyob rau hauv kab nrog cov qauv ntawm cov tawv nqaij ntuj. Qhov yuav tsum tau ua; Lub sijhawm ntawd, txheej saum npoo ntawm cov tawv nqaij cuav tuaj yeem ua tiav cov qauv micro-porous polyurethane txheej, uas yog sib npaug rau cov noob ntawm cov tawv nqaij ntuj, yog li qhov tsos thiab cov qauv sab hauv ntawm PU tawv nqaij cuav maj mam ze rau ntawm cov tawv nqaij ntuj, thiab lwm yam khoom siv lub cev ze rau cov tawv nqaij ntuj. Index, thiab xim ci dua li cov tawv nqaij ntuj; nws qhov kub ib txwm folding tsis kam tuaj yeem ncav cuag ntau dua 1 lab zaug, thiab qhov kub qis folding tsis kam kuj tuaj yeem ncav cuag qib ntawm cov tawv nqaij ntuj.
Ua raws li tawv tawv PVC, tawv PU hluavtaws tau raug tshawb fawb thiab tsim los ntawm cov kws tshaj lij thiab cov kws tshaj lij thev naus laus zis tau ntau tshaj 30 xyoo. Ua ib qho kev hloov pauv zoo tshaj plaws rau tawv ntuj, tawv PU hluavtaws tau ua tiav kev nce qib hauv kev siv tshuab.
