Mukutanga kwezana ramakore rechi20, jira relacquer renitrocellulose rakagadzirwa nejira rekunamira nenitrocellulose sol raive piyona wematehwe ekugadzira.muma1930s, kugadzirwa kwemaindasitiri kwepolyvinyl chloride kwakavhura zviwanikwa zvitsva zvematehwe ekugadzira uye zvakasimudzira kuvandudzwa.dehwe rekugadziraproduction.Iyo paste yakagadzirwa ne polyvinyl chloride ine plasticizer uye stabilizer iri nyore kuve neruvara, uye mushure mekupfekedzwa kwegelatinized, inogona kugadzirwa mumhando dzakawanda dzezvigadzirwa zvine chitarisiko chakafanana nematehwe nekudhinda, embossing kana embossing uye kudhinda.Kufema kwayo uye kupenya kwemvura kunopindirana nematehwe echisikigo, uye ine rimwe simba uye kusagadzikana kweabrasion, kunyanya iri nyore kugadzira, yakawanda mbishi, yunifomu yechigadzirwa mhando, nyore kucheka uye kushandisa, kureruka kurema, kuramba mvura, mutengo wakaderera, saka inoshandiswa zvakanyanya mukushongedza mukati memotokari,zvigaro zvemotokarinezvimwe zvinhu zvemaindasitiri.
Nekuvandudzwa kwemhando dzepurasitiki uye tekinoroji yekugadzira, dehwe rekugadzira rinoumba akasiyana ezvigadzirwa zvakatevedzana.Izvo zvinoshandiswa zvekuputira layer ndeye polyamide, polyurethane, polyolefin, nezvimwewoPVC, iyo yakasvibiswa yekuputira layer inoshandiswa zvakare.Kune zvakare akawanda marudzi emachira epasi, akadai sejira rakatsetseka, canvas, jira rakarukwa, jira remurwi, jira risiri rakarukwa zvichingodaro.Mhando dzakasiyana-siyana uye mavara ekugadzirwa kwematehwe ekugadzira akasiyana zvakare nenzira yekupfekedza uye gelation yehwaro jira repamusoro denga, pamwe nehurongwa hwekupedzisa, senge embossing, kudhinda, kurapwa kwepamusoro uye kuumbwa kwemumiriri wekurapa.
Kugadzirwa kunosanganisira kugadzirwa kwemachira egadziko, kugadzirira kwekunamira, kukoira, laminating, gelation, kurapwa kwepamusoro, embossing, kutonhora, uye mhepo.Pane 4 nzira huru dzekugadzira:
Yakananga coating nzira
Iyo inonamira yakanamirwa yakanangana neiyo pretreated base jira ine squeegee, yobva yaiswa gelled uye nepurasitiki mubhokisi replasticizing, uye yobva yaiswa embossed uye kutonhora kuti iwane chigadzirwa chakapedzwa.Iyi nzira inogona kuburitsa marudzi ese eakajairwa ematehwe echigadzirwa, firimu rekugadzira dehwe uye furo rekugadzira dehwe pachigadziko chemucheka.
Transfer coating method
Iyo inonziwo indirect coating method.Iyo paste yakaputirwa pane inotakura (inoburitsa pepa tepi kana simbi isina simbi tepi) ine reverse roller kana scraper, uye mushure megelation, chigadziko chejira chinozoiswa pamupendero weiyo gelated zvinhu pasi pekunetsekana, uyezve plasticized, yakanyoroveswa uye yakapepetwa. kubva kumutakuri, uye mushure mekurapa, uye chigadzirwa chakapedzwa chinowanikwa.Iyi nzira yakakodzera kugadzirwa kwejira rakarukwa kana jira risiri rakarukwa rakavakirwa furo rekugadzira dehwe uye rakajairwa rekugadzira dehwe.
Calender uye laminating nzira
Zvinoenderana nezvinodiwa fomula, resin, plasticizer uye mamwe maajenti anofananidzwa anoyerwa uye anoiswa mumushini wekukanya kuti asanganise zvakaenzana, obva atumirwa kune matatu-roller kana mana-roller calender (ona epurasitiki muchina calender muhukobvu hunodiwa uye hupamhi hwe. iyo firimu, uye yakanyungudutswa ne pre-heated base jira, uye yobva yanamirwa nekutonhodzwa kuti iwane yapera chigadzirwa.Iyi nzira inogona kugadzira akasiyana marudzi eartificial microfiber dehweneyakasiyana jira base.Kuti uvandudze lamination effect ye base cloth uye firimu, chigadziko chekunamatira chinowanzoiswa pamucheka wekutanga.
Extrusion lamination nzira
Iyo resin, plasticizer uye mamwe maajenti anofananidzwa anosanganiswa zvakanaka mukneader, obva awedzererwa mufirimu reimwe ukobvu uye hupamhi neiyo extruder, uyezve laminated ne preheated base jira pamushini wekuumba matatu-roller, uye wozopera. zvigadzirwa zvinowanikwa nepreheating, laminating, embossing uye kutonhora.
Bensen kambani kugadzirwa kwematehwe ekudzivirira kwezvakatipoteredza ndiko chaikoartificial synthetic dehwe, inonyanya kugadzirwa neresin, yakadai se: inotengeswa kunze kwenyika ine hushamwari polyurethane, polyurethane resin (TPU), nezvimwewo, hupenyu hwebasa hwakareba kupfuura dehwe.Zvakanakira zveganda rakagadzirwa neBensen: Kutanga, ganda rine simba rakanaka rekusimba, kwete nyore kubvarura, rinogara rakasimba;chechipiri, kurwisa ngura, kuita kwakanaka kwekurwisa-abrasion;chechitatu, hapana kunhuhwirira kusingafadzi, uye ine antibacterial, anti-mildew, anti-moth, pasina chero zvinhu zvinokuvadza, maitiro ezvakatipoteredza.
