I-PVC resin ye-synthetic leater
I-PVC resin ye-synthetic leater,
I-PVC yesikhumba sokwenziwa, impahla eluhlaza ye-PVC, inhlaka ye-PVC yesikhumba,
Indwangu yesikhumba ye-PVC ifana kakhulu nendwangu yesikhumba ye-PU.Esikhundleni se-polyurethane, indwangu yesikhumba ye-PVC yenziwa ngokuhlanganisa i-polyvinylchloride ne-stabilizers (ukuvikela), ama-plasticizers (ukuthambisa) nama-lubricant (ukwenza ukuguquguquka), bese usebenzisa kusisekelo.
Isikhumba esisekelwe ku-PVC singenye indlela enkulu kunesikhumba sangempela.Ikhiqizwa ngokufaka esikhundleni seqembu le-hydrogen neqembu le-chloride eqenjini le-vinyl.Lo mkhiqizo ube usuhlanganiswa namakhemikhali ukuze kwenziwe isikhumba sokwenziwa.Impahla enkulu eluhlaza esetshenziswa kule nqubo i-PVC.Isikhumba esenziwe nge-PVC sasiyisikhumba sokuqala sokwenziwa esakhiwa ngeminyaka yawo-1920s.Kubhekwa njengamandla aphezulu kanye nokumelana nezimo zezulu ezihlukahlukene.Kuyinto okulula ukuyigcina futhi ihlanzekile ngakho-ke ithandwa kakhulu ezimbonini ezihlukahlukene.
Inqubo yokukhiqiza isikhumba se-PVC
1.indlela yokuqala yindlela ye-calendering.
ngakho okokuqala kufanele sixube i-PVC eluhlaza kanye ne-pigment njll, futhi senze impahla ibe nesimo esihle esiqinile.
2.sabe sesimboza indwangu exubene, kuze kube le nqubo i-semi-finished material esiyibiza nge-base material.
ngakho-ke izinto eziyisisekelo kufaka phakathi izendlalelo ezi-2: ungqimba lwe-pvc ngaphezulu nokusekelwa yindwangu.
khona-ke izinto eziyisisekelo zizothunyelwa emshinini onamagwebu, okuwumugqa omude wokukhiqiza onezinga lokushisa eliphezulu, izinto ezixubile zizokhipha amagwebu lapha, ngakho-ke i-pvc izoba mkhulu, ugqinsi lwesendlalelo se-pvc bungaphinda kabili ungqimba lwesisekelo se-pvc.
ngemuva kokugwaza, izinto ezizokwenziwa zizoqoshwa ngokuthungwa, lapha sisebenzisa i-embossing roller enokuthungwa ku-roller, ungacabanga ukuthi isikhunta, ukuthungwa ku-roller kuzodluliselwa ebusweni besendlalelo se-pvc, khona-ke singathola okuhlukile. ukuthungwa.
khona-ke sizokwenza ukwelashwa okungaphezulu, njengokulungisa umbala noma ukuphrinta imidwebo ethile ebusweni.
ngezansi ukugeleza kokukhiqizwa kwesikhumba se-pvc
Izici
I-PVC ingenye yezinhlaka ze-thermoplastic ezisetshenziswa kakhulu.Ingasetshenziselwa ukwenza imikhiqizo enobulukhuni obuphezulu namandla, njengamapayipi nokufakwa, iminyango enephrofayili, amafasitela namashidi okupakisha.Ingakwazi futhi ukwenza imikhiqizo ethambile, efana namafilimu, amashidi, izintambo zikagesi nezintambo, amabhodi aphansi kanyeisikhumba sokwenziwa, ngokufaka ama-plasticizers
