Cov tawv tawv siv hauv tsheb sab hauv feem ntau suav nrog PVC (ployvinyl chloride) tawv tawv, PU (poly urethane) tawv tawv, suede zoo li tawv tawv thiab lwm yam.Nws yog ib qho kev xaiv rau cov tawv nqaij thiab yog siv dav hauv cov khoom sab hauv xws li cov rooj zaum, qhov rooj vaj huam sib luag thiab cov pob sib koom ua ke.
1. PVC molding
Lub ntsiab raw khoom ntawm PVC tawv tawv yog PVC, thiab hauv qab yog sib koom nrog knitted ntaub los yog ntaub ntaub.PVC muaj qhov zoo ntawm kev tsim khoom yooj yim, cov khoom zoo ib yam thiab tus nqi qis, tab sis nws cov huab cua permeability thiab noo noo permeability tsis zoo li tawv.Lub hauv paus txheej txheem yog raws li nram no:
① Kev sib xyaw: PVC, nplaim hluav taws, stabilizer thiab xim yog sib xyaw los ntawm lub tshuab nqus tsev twj.
② Txheej: xaiv cov ntawv tso tawm tsim nyog raws li qhov kev ntxhib los mos xaiv los ntawm tus qauv tsim, lossis rov tsim cov ntawv tso tawm raws li kev ntxhib los mos;Txheej sib tov nyob rau hauv cov kauj ruam dhau los ntawm cov ntawv tso tawm, ziab thiab txheej rau ntau zaus kom ncav cuag qhov tsim nyog thickness thiab uniformity;Thaum kawg, cov ntaub ntawv npaj tau raug khi nrog cov coated PVC, thiab tom qab ziab dua, cov ntawv tso tawm thiab cov ntaub yog dov raws li qhov xav tau.
PVC khoom tawv tawv ntau lawm kab yog qhia nyob rau hauv daim duab.
2. Pu molding
Lub ntsiab raw khoom ntawm Pu tawv tawv yog polyurethane, uas muaj cov yam ntxwv ntawm fullness, zoo resilience, tej huab cua permeability thiab ya raws permeability, thiab yog ze rau qhov zoo nkauj ntawm ntuj tawv.High kawg Pu tawv tawv yog kim dua li tawv tiag.Kev tsim cov txheej txheem ntawm cov tawv tawv Pu tawv zoo ib yam li PVC.
Lwm hom tawv tawv uas siv dav siv tam sim no yog superfine fiber ntau PU, uas yog hu ua superfine fiber PU luv luv.Sib txawv ntawm knitted npuag puag ntawm zoo tib yam Pu, lub hauv paus ntawm super fiber PU yog cov ntaub tsis-woven ua los ntawm hiav txwv kob fiber ntau.Island fiber yog ib hom kev sib xyaw fiber ntau.Nyob rau hauv nws cov fiber ntau, cov kev txhawb zog yog tawg nyob rau hauv lub substrate zoo li cov Islands tuaj, yog li nws muaj npe.Tom qab cov ntaub ntawv super fiber ntau yog woven rau hauv cov duab, nws yog tsim los rau hauv ib tug super fiber puag txheej los ntawm immersion thiab lwm yam txheej txheem, uas muaj ib tug zoo nkauj zoo nkauj dua li PU.Kev tsim cov txheej txheem ntawm lub hauv paus ntaub yog xa mus rau qhov txuas:
PVC tawv tawv ntau lawm kab
①Weaving: xaiv qhov tsim nyog cov kob sib xyaw fiber ntau, tsim nws los ntawm kev sib tw, spunlace thiab lwm yam tsis-woven txoj kev, thiab tom qab ntawd ua nws los ntawm kev siv lub cev.
②Impregnation: lub hauv paus ntaub ntaub yog impregnated nyob rau hauv resin, impregnated, solidified, ntxuav, thiab cov txheej txheem saum toj no yog rov qab, thiab ces ua tiav thiab dov los tsim ib tug super fiber puag ntaub.
Super fiber ntau PU tau txais tom qab Pu yog coated rau saum npoo ntawm super fiber puag ntaub.Cov txheej txheem txheej txheej saum npoo zoo ib yam li cov Pu thiab PVC.
