PVC resin mo le synthetic leater
PVC resin mo le synthetic leater,
PVC mo pa'u fa'akomepiuta, PVC pa'u mea mata, PVC resin mo pa'u,
O le ie pa'u PVC e tutusa lelei ma le ie pa'u PU.Nai lo le polyurethane, o le ie paʻu PVC e faia e ala i le tuʻufaʻatasia o le polyvinylchloride faʻatasi ma mea faʻamautu (e puipuia), palasitika (e faʻamalulu) ma lubricants (ia faʻafefeteina), ona faʻaoga lea i se mea faʻavae.
O le pa'u fa'avae PVC o se suiga tele i le pa'u moni.E gaosia e ala i le suiina o le hydrogen group i le chloride group i le vinyl group.O lenei oloa e fa'afefiloi ma vaila'au e fa'atupu ai le pa'u synthetic.O le tele o mea faʻaaogaina i lenei faagasologa o le PVC.O le pa'u fa'avae PVC o le pa'u synthetic muamua na faia i le 1920s.E manatu e maualuga le malosi ma tetee atu i tulaga tau tau eseese.O se mea e faigofie ona tausia ma mama ma o lea e sili ona fiafia i pisinisi eseese.
Fa'agasologa o le gaosiga o pa'u PVC
1.le auala muamua o le calendering auala.
o le mea muamua e tatau ona tatou faʻafefiloi le PVC mea mata ma le pigment etc, ma faia le mea i se foliga mausali lelei.
2.ona matou faʻapipiʻiina lea o mea faʻafefiloi i luga o le ie, seia oʻo i lenei faʻagasologa o mea semi-maea matou te taʻua o mea faʻavae.
o le mea autu e aofia ai le 2 layers: pvc layer i luga ma le lagolago o le ie.
ona tuʻuina atu lea o mea faʻavae i totonu o se masini faʻafefe, o se laina gaosiga umi ma le maualuga o le vevela, o le a faʻafefiloi mea faʻafefiloi iinei, o lea o le a sili atu le mafiafia o le pvc, o le mafiafia o le pvc layer e mafai ona faaluaina le faavae pvc layer.
a maeʻa le faʻafefe, o mea o le a faʻapipiʻiina i le mea, o iinei tatou te faʻaogaina ai le embossing roller o loʻo i ai le mea i luga o le uila, e mafai ona e manatu o se faʻailoga, o le a faʻafeiloaʻi le lanu i luga o le lapisi pvc, ona mafai lea ona tatou maua ese. fua.
ona matou faia lea o togafitiga i luga, pei o le fetuutuunai o le lanu poʻo le lolomiina o ni ata i luga o le fogaeleele.
lalo o le tafega gaosiga o le pa'u pvc
Vaega
PVC o se tasi o resins thermoplastic sili ona faʻaaogaina.E mafai ona faʻaaogaina e fai ai oloa e maualuga le maaa ma le malosi, e pei o paipa ma mea faʻapipiʻi, faitotoa faʻailoga, faamalama ma laupepa afifi.E mafai foʻi ona fai ni mea vaivai, e pei o ata tifaga, laupepa, uaea eletise ma uaea, laupapa fola mapa'u gaosia, e ala i le faʻaopoopoga o mea faʻapipiʻi
