Resin ea PVC bakeng sa leater ea maiketsetso,
PVC bakeng sa letlalo la Synthetic, PVC Letlalo thepa e tala, PVC resin bakeng sa letlalo,
Lesela la letlalo la PVC le tšoana haholo le lesela la letlalo la PU.Ho e-na le polyurethane, lesela la letlalo la PVC le entsoe ka ho kopanya polyvinylchloride le li-stabilizers (ho sireletsa), li-plasticizers (ho nolofatsa) le litlolo (ho etsa hore li feto-fetohe), ebe li sebelisa lisebelisoa tsa motheo.
Letlalo le thehiloeng ho PVC ke khetho e kholo ho feta letlalo la 'nete.E hlahisoa ka ho nkela sehlopha sa hydrogen sebaka le sehlopha sa chloride sehlopheng sa vinyl.Joale sehlahisoa sena se kopantsoe le lik'hemik'hale ho etsa letlalo la maiketsetso.Thepa e ka sehloohong e sebelisoang ts'ebetsong ena ke PVC.Letlalo le thehiloeng ho PVC e bile letlalo la pele la maiketsetso le entsoeng ka bo-1920.E nkoa e le matla a phahameng le ho hanyetsa maemo a sa tšoaneng a leholimo.Ke ntho e bonolo ho e hlokomela ebile e hloekile, ka hona e ratoa haholo liindastering tse fapaneng.
Ts'ebetso ea ho etsa letlalo la PVC
1. tsela ea pele ke calendering tsela.
kahoo pele re lokela ho kopanya thepa e tala PVC le pigment joalo-joalo, 'me re etse thepa ka sebōpeho se setle se tiileng.
2.ka nako eo re ile ra roala lintho tse tsoakiloeng lesela, ho fihlela ts'ebetso ena e se e felile, re e bitsa lisebelisoa tsa motheo.
kahoo thepa ea motheo e kenyeletsang 2 layers: pvc layer holim'a metsi le tšehetso ke lesela.
joale thepa ea motheo e tla romelloa ka mochine o phophomang, e leng mohala o molelele oa tlhahiso o nang le mocheso o phahameng, thepa e tsoakiloeng e tla phophoma mona, kahoo pvc e tla ba e teteaneng, botenya ba pvc layer bo ka ba habeli ba setsi sa pvc.
ka mor'a ho phophoma, thepa e tla kenngoa ka mokhoa o hlophisitsoeng, mona re sebelisa embossing roller e nang le sebopeho holim'a rolara, u ka nahana hore ke hlobo, sebopeho se holim'a rolara se tla fetisetsoa holim'a pvc layer, joale re ka fumana tse fapaneng. sebopeho.
ka nako eo re tla etsa kalafo ea holimo, joalo ka ho fetola 'mala kapa ho hatisa litšoantšo tse ling holimo.
ka tlase ke phallo ea tlhahiso ea letlalo la pvc
Likaroloana
PVC ke e 'ngoe ea li-resin tsa thermoplastic tse sebelisoang haholo.E ka sebelisoa ho etsa lihlahisoa tse nang le boima bo phahameng le matla, joalo ka liphaephe le li-fittings, mamati a profild, lifensetere le lipampiri tsa ho paka.E ka boela ea etsa lihlahisoa tse bonolo, tse kang lifilimi, maqephe, lithapo tsa motlakase le lithapo, liboto tsa fatše leletlalo la maiketsetso, ka ho eketsa li-plasticizers
