Nyob rau hauv lub xyoo pua 20th thaum ntxov, nitrocellulose lacquer daim ntaub ua los ntawm txheej ntaub nrog nitrocellulose sol yog tus pioneer ntawm tawv tawv.Nyob rau xyoo 1930, kev tsim khoom ntawm polyvinyl chloride tau qhib rau cov khoom siv tshiab rau cov tawv tawv thiab txhawb kev txhim kho ntawmtawv tawvntau lawm.Cov tshuaj nplaum ua los ntawm polyvinyl chloride nrog cov yas yas thiab stabilizer yog ib qho yooj yim rau xim, thiab tom qab txheej txheej yog gelatinized, nws tuaj yeem ua rau ntau yam khoom uas zoo li tawv los ntawm kev luam ntawv, embossing lossis embossing thiab luam ntawv.Nws breathability thiab noo noo permeability yog raws li ntuj tawv, thiab nws muaj tej yam lub zog thiab puas kuj, tshwj xeeb tshaj yog nws yog ib qho yooj yim los tsim, ntau raw cov ntaub ntawv, uniform khoom zoo, yooj yim rau txiav thiab siv, lub teeb yuag, dej tsis kam, tsis muaj nqi, yog li nws tau dav siv hauv tsheb sab hauv kho kom zoo nkauj,lub rooj zaumthiab lwm yam kev lag luam accessories.
Nrog rau txoj kev loj hlob ntawm cov yas ntau yam thiab kev siv tshuab, cov tawv tawv tsim ntau yam khoom siv.Cov ntaub ntawv raw ntawm txheej txheej yog polyamide, polyurethane, polyolefin, thiab lwm yamPVC, cov ntaub ntawv raw ntawm txheej txheej kuj siv.Kuj tseem muaj ntau hom ntaub hauv paus, xws li daim ntaub tiaj tus, canvas, knitted fabric, pawg ntaub, ntaub tsis-woven thiab lwm yam.Ntau yam thiab xim ntawm cov tawv nqaij tsim tawm kuj txawv ntawm txoj kev ntawm txheej thiab gelation ntawm lub hauv paus ntaub nto txheej, nrog rau kev txiav txim ntawm cov txheej txheem tiav, xws li embossing, luam ntawv, kho deg thiab muaj pes tsawg leeg ntawm tus neeg sawv cev kho deg.
Kev tsim khoom suav nrog kev kho cov ntaub hauv qab, kev npaj nplaum, txheej, laminating, gelation, kho deg, embossing, txias, thiab winding.Muaj 4 txoj kev tsim khoom loj:
Direct txheej txheej
Cov ntaub nplaum yog ncaj qha coated rau ntawm pretreated puag ntaub nrog ib tug squeegee, ces nws yog gelled thiab plasticized nyob rau hauv lub plasticizing lub thawv, thiab ces nws yog embossed thiab txias kom tau cov khoom tiav.Txoj kev no tuaj yeem tsim tau txhua yam ntawm cov tawv nqaij zoo tib yam, zaj duab xis tawv tawv thiab ua npuas ncauj tawv tawv ntawm ntaub puag.
Hloov txheej txheej
Kuj hu ua indirect txheej txheej.Cov muab tshuaj txhuam yog coated rau ntawm cov cab kuj (tso daim ntawv daim kab xev los yog stainless hlau daim kab xev) nrog ib tug rov qab cov menyuam los yog scraper, thiab tom qab gelation, lub hauv paus ntaub yog laminated nyob rau hauv lub gelated cov ntaub ntawv txheej nyob rau hauv tsis muaj tensioned, thiab ces plasticized, txias thiab tev tawm. los ntawm tus neeg nqa khoom, thiab tom qab ntawd kho, thiab cov khoom tiav tau txais.Txoj kev no yog tsim rau zus tau tej cov ntaub knitted los yog non-woven npuag raws li ua npuas ncauj tawv tawv thiab ntau yam tawv tawv.
Calendering thiab laminating txoj kev
Raws li cov qauv xav tau, resin, plasticizer thiab lwm yam khoom sib txuam raug ntsuas thiab muab tso rau hauv lub tshuab kneading kom sib tov sib npaug, thiab tom qab ntawd xa mus rau peb-cov menyuam los yog plaub-cov menyuam calender (saib cov tshuab yas calendering rau hauv qhov xav tau tuab thiab dav. zaj duab xis, thiab laminated nrog pre-rhuab puag daim ntaub, thiab ces embossed thiab txias kom tau cov khoom tiav. Txoj kev no tuaj yeem tsim ntau yam.artificial microfiber tawvnrog sib txawv ntaub puag.Txhawm rau txhim kho cov nyhuv lamination ntawm lub hauv paus ntaub thiab zaj duab xis, ib txheej ntawm cov nplaum feem ntau siv rau ntawm daim ntaub ua ntej.
Extrusion lamination txoj kev
Cov resin, plasticizer thiab lwm yam khoom sib txuam yog sib xyaw zoo hauv lub kneader, thiab tom qab ntawd extruded rau hauv ib txheej zaj duab xis ntawm tej thickness thiab dav los ntawm extruder, thiab tom qab ntawd laminated nrog preheated puag ntaub ntawm peb-cov menyuam shaping tshuab, thiab tom qab ntawd ua tiav. cov khoom yog tau los ntawm preheating, laminating, embossing thiab txias.
Bensen tuam txhab tsim khoom ntawm ib puag ncig tiv thaiv tawv yog tiag tiaghluavtaws hluavtaws tawv, feem ntau yog ua los ntawm cov resin, xws li: imported environmentally friendly polyurethane, polyurethane resin (TPU), thiab lwm yam., kev pab lub neej yog ntev tshaj li tawv.Qhov zoo ntawm cov tawv tawv uas tsim los ntawm Bensen: Ua ntej, cov tawv nqaij muaj zog tensile zoo, tsis yooj yim los tsim kua muag, ruaj khov dua;thib ob, corrosion kuj, zoo tiv thaiv kev ua haujlwm;thib peb, tsis muaj ntxhiab tsw ntxhiab, thiab muaj cov kab mob tua kab mob, tiv thaiv kab mob, tiv thaiv kab mob, tsis muaj teeb meem tshuaj, ib puag ncig yam ntxwv.
