I-PU synthetic leather isikhumba esenziwe nge-polyurethane.Manje isetshenziswa kabanzi ukuhlobisa imithwalo, izingubo zokugqoka, izicathulo, izimoto kanye nefenisha.Sekuqashelwa kakhulu yimakethe.Ububanzi bayo besicelo esibanzi, inani elikhulu nezinhlobonhlobo eziningi azineliseki ngesikhumba semvelo sendabuko.Izinga le-PU lesikhumba nalo lihle noma libi.Isikhumba esihle se-PU sibiza kakhulu kunesikhumba, esinomphumela omuhle wokubunjwa kanye nendawo ekhanyayo.
01: Izinto ezibonakalayo kanye nezici
Isikhumba sokwenziwa se-PU sisetshenziswa esikhundleni sesikhumba sokwenziwa se-PVC, futhi intengo yaso iphakeme kunesikhumba sokwenziwa se-PVC.Mayelana nesakhiwo samakhemikhali, iseduze nendwangu yesikhumba.Ayidingi i-plasticizer ukufeza izakhiwo ezithambile, ngakho-ke ngeke ibe nzima futhi ibe brittle.Ngesikhathi esifanayo, inezinzuzo zemibala ecebile namaphethini ahlukahlukene, futhi intengo ngokuvamile ishibhile kunendwangu yesikhumba, ngakho-ke iyamukelwa abathengi.
Enye iyisikhumba se-PU.Ngokuvamile, uhlangothi olungemuva lwesikhumba se-PU ungqimba lwesibili lwesikhumba esingavuthiwe, olumbozwe ngongqimba lwe-PU resin, ngakho lubizwa nangokuthi isikhumba senkomo yefilimu.Intengo yayo ishibhile futhi izinga lokusebenzisa kwayo liphezulu.Ngokushintsha kobuchwepheshe, ibuye yenziwe ibe izinhlobo zamabanga ahlukahlukene, njengesikhumba esiluhlaza esingenisiwe esinezendlalelo ezimbili.Ngenxa yobuchwepheshe bayo obuyingqayizivele, ikhwalithi ezinzile, izinhlobo zamanoveli nezinye izici, yisikhumba samanje sezinga eliphezulu, futhi intengo yayo kanye nebanga akukho ngaphansi kwesikhumba sokuqala.Isikhumba se-PU nesikhumba sangempela sinezici zazo.Ukubukeka kwesikhumba se-PU kuhle futhi kulula ukusinakekela.Inani liphansi, kodwa alikwazi ukumelana nokugqoka futhi kulula ukuliphula;Isikhumba sangempela siyabiza, sinzima ukusinakekela, kodwa sihlala isikhathi eside.
(1) Amandla aphezulu, azacile futhi anwebeka, athambile futhi abushelelezi, ukuphefumula okuhle nokungena kwamanzi, nokungangeni kwamanzi.
(2) Emazingeni okushisa aphansi, isenamandla amahle okuqina namandla aguquguqukayo, ukumelana nokuguga kokukhanya okuhle kanye nokumelana ne-hydrolysis.
(3) Ayizweli ekugugeni, futhi ukubukeka kwayo nokusebenza kwayo kusondelene naleyo yesikhumba semvelo.Kulula ukuwasha, ukususa ukungcola nokuthunga.
(4) Ingaphezulu libushelelezi futhi lihlangene, elingasetshenziselwa ukwelapha okuhlukahlukene nokudaya.Izinhlobonhlobo zihlukahlukene futhi intengo iphansi kakhulu.
(5) Ukumuncwa kwamanzi akulula ukunwetshwa nokonakala, futhi kuyahambisana nemvelo.
02: Inqubo yomkhiqizo nokuhlukaniswa
Isikhumba se-Nubuck: Ngemva kokuxubha, okuphuzi okukhanyayo nombala, ubuso baso bucutshungulwa ungqimba oluphezulu olufana nezinwele ezinhle zesikhumba se-suede.Njengoba kuwuhlobo lwesikhumba esiphezulu, nakuba amandla esikhumba abuye abe buthaka ngenqubo yokudweba ngezinga elithile, kusenamandla kakhulu kunesikhumba esivamile se-suede.
Isikhumba sehhashi esihlanyayo: Sinomuzwa wesandla obushelelezi, sivumelana nezimo futhi siqinile, sinezinyawo ezinwebekayo, futhi isikhumba sizoshintsha umbala uma siphushwa ngesandla.Kumele senziwe ngesikhumba sesilwane esingaphansi kwekhanda lemvelo.Ngenxa yokuthi isikhumba sehhashi sinokushelela kwemvelo namandla, iningi labo lisebenzisa isikhumba sehhashi lesendlalelo sekhanda.Kodwa-ke, ngenxa yokuthi le nqubo yokwenza isikhumba ithatha isikhathi esiningi, inezinto zokusetshenziswa ezimbalwa uma kuqhathaniswa, futhi inezindleko eziphezulu, isikhumba sehhashi i-Crazy sivamile kuphela emakethe yesikhumba ephakathi nendawo ephezulu.
Isikhumba sesibuko se-PU: ingaphezulu libushelelezi.Isikhumba siphathwa ikakhulukazi ukwenza ubuso bucwebezele futhi bubonise umphumela wesibuko.Ngakho-ke, kubizwa ngokuthi isikhumba sesibuko.Impahla yayo ayilungisiwe kakhulu.
I-Ultrafine fiber synthetic leather: wuhlobo olusha lwesikhumba sokwenziwa sezinga eliphezulu esenziwe ngemicu emihle kakhulu.Abanye abantu bayibiza ngesizukulwane sesine sesikhumba sokwenziwa, esiqhathaniswa nesikhumba semvelo esisezingeni eliphezulu.Inomuncwa ongokwemvelo womswakama kanye nokungena komoya kwesikhumba semvelo, futhi iphakeme kunesikhumba semvelo ekuphikisweni kwamakhemikhali, ukumelana namanzi, ukumelana nesikhutha, njll.
Isikhumba esigeziwe: Isikhumba se-retro PU, esasidumile eminyakeni emibili edlule, ukufaka ungqimba lukapende osuselwe emanzini esikhumbeni se-PU, bese wengeza i-asidi ukuyigeza emanzini ukucekela phansi ukwakheka kopende ongaphezulu. isikhumba esigeziwe, ukuze izindawo eziphakanyisiwe ebusweni ziphele ukuze zibonise umbala wangemuva, kuyilapho izindawo ze-concave zigcina umbala wokuqala.Isikhumba esigeziwe sisenziwe.Ukubukeka nokuzwakala kwayo kufana kakhulu nesikhumba.Nakuba ingaphefumuli njengesikhumba, ilula futhi ingawashwa.Intengo yayo ishibhile kakhulu kunesikhumba.
Umswakama wesikhumba ophulukisiwe: Ungumkhiqizo wepulasitiki owenziwe inqubo ethile yokucubungula, okuyingxube ye-polyvinyl chloride resin, i-plasticizer nezinye izithasiselo, eziboshwe noma ezinamathiselwe phezu kwendwangu.Ngaphezu kwalokho, kukhona nesikhumba sokwenziwa se-PVC esinezinhlangothi ezimbili ezinezendlalelo zepulasitiki nhlangothi zombili ze-substrate.
Isikhumba esiguquliwe: Senziwa ngokwengeza inhlaka eguquliwe endaweni ye-PU kanye nongqimba lwe-BASE lwesikhumba, ukucwiliswa, bese kucutshungulwa ukumbozwa kwephepha noma ukugqamisa, nokuphrinta.Ngemuva kokucindezela okushisayo komshini oshisayo, ingaphezulu lesikhumba esishintshashintshayo esicindezelwe esishisayo sibhekana nokusabela okufanayo kwe-carbonization, elingisa umaki oshiywe yisikhumba esishile lapho sivezwa izinga lokushisa eliphezulu, okuholela esikalini sombala omnyama. yendawo ecindezelwe eshisayo, ngakho ibizwa ngesikhumba esicindezelwe esishisayo esishintsha umbala.
