PU synthetic leather iganda rakagadzirwa kubva paganda re polyurethane.Iye zvino inoshandiswa zvakanyanya kushongedza mikwende, zvipfeko, shangu, mota uye fenicha.Yave ichiwedzera kuzivikanwa nemusika.Kuwanda kwayo kwekushandisa kwakakura, huwandu hukuru uye marudzi mazhinji haagutsikane nematehwe echinyakare echinyakare.Hunhu hwePU dehwe zvakare hwakanaka kana hwakashata.Yakanaka PU yematehwe inotodhura kupfuura dehwe, ine yakanaka kuumbwa maitiro uye inopenya pamusoro.
01: Material zvivakwa uye maitiro
PU synthetic dehwe rinoshandiswa kutsiva PVC yedehwe rekugadzira, uye mutengo wayo wakakwira kupfuura PVC yematehwe ekugadzira.Maererano nekugadzirwa kwemakemikari, iri pedyo nemucheka weganda.Haidi plasticizer kuti iwane zvinyoro zvinyoro, saka haizove yakaoma uye brittle.Panguva imwecheteyo, ine zvakanakira mavara akapfuma uye mapatani akasiyana, uye mutengo unowanzo kudhura kupfuura jira rematehwe, saka inogamuchirwa nevatengi.
Imwe yacho iPU dehwe.Kazhinji, iro rakadzokera kumashure rePU rematehwe ndiro rechipiri rematehwe mbishi, iro rakaputirwa nepu resin, saka inonziwo firimu redehwe remombe.Mutengo wayo wakachipa uye mwero wekushandiswa kwayo wakakwira.Nekuchinja kwehunyanzvi, inogadzirwawo kuva mhando dzemagiredhi akasiyana-siyana, seyakaunzwa kunze-mbiri-law yematehwe mbishi.Nekuda kweiyo yakasarudzika tekinoroji, yakagadzikana mhando, mhando dzakasiyana uye humwe hunhu, ndiyo yazvino yepamusoro-giredhi dehwe, uye mutengo wayo uye giredhi hazvisi zvishoma pane yekutanga layer yematehwe.PU dehwe uye ganda rechokwadi vane maitiro avo.Kuonekwa kwePU ganda rakanaka uye nyore kuchengeta.Mutengo wacho wakaderera, asi hausi kupfeka uye nyore kuputsa;Dehwe rechokwadi rinodhura, rinonetsa kutarisira, asi rinogara.
(1) Simba repamusoro, rakatetepa uye rakapfava, rakapfava uye rakatsetseka, kufema kwakanaka uye kugona kwemvura, uye kusapinda mvura.
(2) Pakupisa kwakadzika, ichiri nesimba rakanaka rekusimba uye simba rekushanduka-shanduka, chiedza chakanaka chekuchembera kuramba uye hydrolysis kuramba.
(3) Haikodzeri kupfeka, uye chitarisiko chayo uye kuita kwayo zviri pedyo nematehwe echisikigo.Zviri nyore kugeza, kubvisa uye kusona.
(4) Iyo yepamusoro inotsvedzerera uye yakatsikirira, iyo inogona kushandiswa kwakasiyana-siyana kwepamusoro kurapwa uye kudhaya.Izvo zvakasiyana-siyana zvakasiyana uye mutengo wacho wakaderera.
(5) Kunyura kwemvura hakusi nyore kuwedzera nekukanganisa, uye kune hushamwari.
02: Maitiro echigadzirwa uye kurongedza
Nubuck leather: Mushure mekutsvaira, chiedza chero uye chine ruvara, nzvimbo yaro inogadziriswa kuva yepamusoro yakafanana nebvudzi rakanaka reganda re suede.Sezvo iri rudzi rweganda repamusoro, kunyangwe simba rematehwe rakaderedzwawo nekudhirowa maitiro kune imwe nhanho, ichiri yakasimba kupfuura yakajairwa suede dehwe.
Dehwe rebhiza rinopenga: Rine kutsetseka kweruoko, rinopfakanyika uye rakasimba, rine tsoka dzakatsetseka, uye ganda rinochinja ruvara kana richisundwa neruoko.Inofanira kugadzirwa neakasikwa musoro layer yeganda remhuka.Nekuti ganda rebhiza rine kutsvedzerera kwechisikigo uye simba, vazhinji vavo vanoshandisa musoro layer yebhiza ganda.Nekudaro, nekuti iyi yekugadzira matehwe inotora nguva yakawanda, ine zvishoma zvishoma, uye ine mutengo wakakwira, Crazy bhiza dehwe rinongowanikwa pakati nepamusoro-soro musika wematehwe.
PU girazi rematehwe: iyo yepamusoro yakatsetseka.Dehwe rinonyanya kurapwa kuti riite kupenya uye kuratidza girazi mhedzisiro.Nokudaro, inonzi girazi reganda.Zvinhu zvayo hazvina kunyatsogadziriswa.
Ultrafine faibha synthetic dehwe: imhando nyowani yemhando yepamusoro-giredhi rekugadzira dehwe rakagadzirwa neshinda dzakanyanya kunaka.Vamwe vanhu vanoidana chizvarwa chechina cheganda rekugadzira, iro rinofananidzwa nepamusoro-grade yeganda rezvisikwa.Iyo ine inherent yehunyoro hwekutora uye kupenya kwemhepo kweganda rechisikigo, uye yakakwirira kune yechisikigo dehwe mukupokana nemakemikari, kuramba mvura, mildew kuramba, nezvimwe.
Dehwe rakashambidzwa: Retro PU dehwe, iro raizivikanwa makore maviri apfuura, nderekuisa pendi yemvura-inobva paganda rePU, wobva wawedzera asidhi yekuigeza mumvura kuti iparadze chimiro chepende pamusoro pe. ganda rakashambidzwa, kuitira kuti nzvimbo dzakasimudzwa pamusoro dzipere kuratidza ruvara rwemashure, nepo nzvimbo dzeconcave dzichichengeta ruvara rwekutanga.Dehwe rakagezwa nderokugadzira.Chitarisiko chayo uye manzwiro akafanana zvakanyanya nematehwe.Kunyange zvazvo isingafemeki sezvinoita dehwe, ine chiedza uye inogona kuwachwa.Mutengo waro wakachipa zvikuru kupfuura dehwe.
Kunyorova kwakarapwa dehwe: Chigadzirwa chepurasitiki chakagadzirwa neimwe nzira yekugadzirisa, inova musanganiswa wepolyvinyl chloride resin, plasticizer uye zvimwe zvinowedzera, zvakaputirwa kana kunamirwa pamusoro pejira.Pamusoro pezvo, kune zvakare mativi maviri-mativi ePVC ematehwe ekugadzira ane mapurasitiki akaturikidzana pamativi ese e substrate.
Dehwe rakasvibiswa: Inogadzirwa nekuwedzera discolored resin muPU pamusoro peiyo uye BASE layer yedehwe, inonyura, yobva yagadzirisa kuburitsa bepa rakavharika kana embossing, uye kudhinda.Mushure mekupisa kwekupisa kwemuchina wekupisa unopisa, pamusoro peganda rinopisa rakadzvanywa rinoiswa kune yakafanana carbonization reaction, kutevedzera mucherechedzo wakasiiwa nedehwe rakatsva kana rave pahupamhi hwekushisa, zvichikonzera kusviba kwemavara eruvara. yenzvimbo inopisa yakadzvanywa, saka inonzi hot pressed discolored dehwe.
