Ukwelashwa kwendawo kunguchungechunge lwezinqubo ezihlela ungqimba olungaphandle lwezinto ukuze kuthuthukiswe ukunamathela, ukumelana nokuguga, ukumelana namakhemikhali, nokusebenza okuhle. Ezimbonini ezithuthukisiwe zokukhiqiza nezingubo, ukwelashwa kwendawo okusebenzayo kunquma impilo nokwethembeka kwezingxenye, amafilimu, nemihlangano. Amabhizinisi ahlola izinketho zokuqeda kufanele alinganise izindleko zenqubo, ukuhambisana nezingubo ezilandelayo, kanye neziqondiso zemvelo ngenkathi kufezekiswa izakhiwo ezisebenzayo ezingaguquki. Lesi sihloko sihlanganisa izilinganiso zaselebhu, amasu ezimboni, namasu okugcinwa asebenzayo ukusiza onjiniyela, abaphathi bokuthenga, nabathuthukisi bemikhiqizo ukuthi benze izinqumo ezisekelwe kudatha. I-Guangdong 提力新材料科技有限公司 (Tili New Materials) ihlanganisa izimiso eziningi kulokhu ekuthuthukisweni kwayo kwezingubo futhi inikeza ukwesekwa okwenziwe ngokwezifiso kumakhasimende adinga ukulungiswa kwe-substrate okwenziwe kahle ngaphambi kokufakwa kwezingubo.

Izindlela eziningana zokwelashwa kwezindawo ezisetshenziswa ezimbonini zisetshenziswa kabanzi kumafilimu epolima nezindawo zensimbi. Ukwelashwa nge-Corona kufaka isivinini esiphezulu ukuze kwandiswe amandla endawo kumaplastiki namafilimu, kukhuthaza ukumanziswa kwamalaka nokunamathiselayo. Ukwelashwa nge-flame kugcoba indawo ngomlilo olawulwayo ukuze kwakhe amaqembu asabelayo athuthukisa ukunamathiselwa kwezinto ezimbozayo, indlela esetshenziswa kakhulu kuma-polyolefins. Ukwelashwa nge-plasma, kusetshenziswa i-plasma enomfutho ophansi noma eyomoya, kunikeza ukusebenza kwamakhemikhali okunembayo ngaphandle komthwalo omkhulu wokushisa futhi kufaneleka ezindaweni ezibucayi ekushiseni. Izinqubo zokuqondisa njenge-OPP (oriented polypropylene) zidinga ukuphathwa okukhethekile ngoba ukuqondisa ngomshini kungathinta indlela ukwelashwa kwe-corona noma i-plasma okushintsha ngayo amakhemikhali endawo; ukuqonda ukwakheka kwefilimu eyisisekelo kubalulekile ukuze kutholwe imiphumela ephindaphindeka. Ukukhetha phakathi kwe-corona, i-flame, i-plasma, noma ukwelashwa okuhlanganisiwe kuncike ohlotsheni lwesubstrate, amazinga edayini adingekayo, isivinini sokukhiqiza, nokuqina kwesikhathi eside kwendawo elungisiwe.

Amandla angaphezulu, alinganiswa ngama-dyne ngesentimitha (dynes/cm), yiyona metric eyinhloko esetshenziselwa ukukala ukusebenza kokwelashwa. Amaplastiki angaphandle avame ukuba namandla angaphezulu aphansi futhi adinga ukwelashwa ukuze afinyelele umkhawulo oqinisekisa ukuthi izinto zokugcoba, amapende, noma izinto zokunamathelisa zibambelela kahle. Ezinhlelweni eziningi zokugcoba ezisekelwe emanzini nezisekelwe kusolvent, izinhloso ezisebenzayo zisukela ku-38 kuye ku-52 dynes/cm, kuye ngokwakhiwa; izinto zokugcoba ezikhethekile ezinokusebenza okuphezulu zingadinga izilinganiso eziphakeme ukuze ziqinisekise amandla okubambelela. Amathuluzi afana ne-dyne pens kanye ne-tensiometers ahlinzeka ngokuqapha okuvamile emgqeni wokukhiqiza, kanti ukuhlaziywa okuphezulu kwangaphandle (okuzoxoxwa kamuva) kuhlobanisa izilinganiso ze-dyne nokusebenza kwamakhemikhali. Ukulawula amazinga e-dyne ngesikhathi sokukhiqiza kuthinta ngqo amazinga amaphutha afana nokubambelela okungalungile, ukuqubuka, noma ukumbozwa okungalingani, ngakho-ke kuthinta ukukhiqiza, izindleko zewaranti, kanye nokwaneliseka kwamakhasimende.

Ukuphulukiswa kokwelashwa—noma ukubuyiselwa kwama-hydrophobic—kuyinselele ejwayelekile: izindawo eziphathwe zibuyela kancane kancane esimweni sazo sokuqala esiphansi samandla ngokuhleleka kabusha kwezintambo, ukungcola, noma ukuchayeka emvelweni. Izinga lokubola lincike ekuhambeni kwamapholima, ezimweni zokugcina, ukuthintana nama-plasticizer, nokuchayeka ezintweni ezithwala umoya. Izindlela zokunciphisa zihlanganisa ukufaka izendlalelo ngokushesha ngemuva kokwelashwa, ukusebenzisa izendlalelo zokuvikela noma ama-primeri akhiya amandla aphezulu, ukugcina amabhola aphathwe ngaphansi komswakama olawulwayo nokushisa, nokukhetha izindlela zokwelashwa eziqhubekayo njenge-plasma enomfutho ophansi eyethula izinguquko ze-covalent. Izilawuli zokusebenza njengeziteshi zokwelashwa ngesikhathi esifanele emgqeni wokukhiqiza kanye nezinhlelo ze-corona ezisebenzayo zinganciphisa isikhathi sokulinda phakathi kokwelashwa nokufakwa kwezendlalelo; le ndlela esebenzayo inciphisa ukwenqatshwa futhi izinzisa ukusebenza kwezendlalelo kuwo wonke ama-batch.

Ukwelashwa kwangemuva kwenzeka lapho izinhlangothi zombili zewebhu noma ifilimu zithola ukuguqulwa kwendawo ngengozi noma ngokuklanywa, okungaholela ezinkingeni zokuphatha njengokubambana (ukubambana kwezendlalelo) noma ukudluliselwa kokungcola ngesikhathi sokuhlanganisa. Ezinqubweni lapho uhlangothi olulodwa kuphela olufanele ukusebenza—isibonelo, lapho kuphrintwa noma kuconswelwa kuphela isitokwe sobuso—ukwelashwa kwangemuva okungahlosiwe kuguqula ukungqubuzana, ukungezwani kokubopha, nokuziphatha kokukhululwa. Ukuphatha imiphumela yangemuva kudinga ukulungiswa kwemishini okunembayo: ukufihla, ukubekwa kwe-electrode okulawulwayo, kanye nezimpawu zomoya ezihleliwe kunciphisa ukukhishwa okungalindelekile. Lapho ukwelashwa kwangemuva kufiseleka—njengendlalelo yokukhululwa noma ukuthuthukisa ukuhlanganisa—onjiniyela balungisa ngamabomu amandla nendlela yewebhu ukudala amazinga ahlukene e-dyne. Ukubhalisa nokuqapha ama-dyne/cm ezinhlangothini zombili kanye nokuqhuba ukuhlolwa okujwayelekile kwama-roll kusiza ukuvimbela izimanga zokusebenza ezingabambezela ukukhiqiza nokwandisa udoti.

I-X-ray Photoelectron Spectroscopy (XPS) iyithuluzi elinamandla lokuhlaziya ukuze kuqondwe izinguquko zamakhemikhali ezibangelwa ukwelashwa kwendawo ezingeni le-athomu. Ngenkathi izilinganiso ze-dyne zikhombisa ukuziphatha okubanzi kokumanzi, i-XPS ihlinzeka ngolwazi lwezingxenye zamakhemikhali nesimo samakhemikhali kungqimba olungaphakathi kuka-5–10 nm, okwenza kube nokuxhumana phakathi kwamaqembu asebenzayo (isibonelo, i-hydroxyl, i-carbonyl, i-carboxyl) nokusebenza kokunamathela. Ngocwaningo nokuhlaziywa kwezinkinga, i-XPS iveza ukuthi ukwelashwa kukhiqiza izinguquko ezizinzile ze-covalent noma ukugqwala nje indawo engaphezulu. Ukuhlanganisa idatha ye-XPS ne-contact angle kanye nokuhlolwa kwe-peel kunikeza ulwazi lokulungiswa kwefomula: ama-primer, abakhuthazi bokunamathela, noma izinguquko ekhemistrini yokwelapha zingaklanywa ukuze zihambisane nekhemistri yangempela yendawo. Le ndlela eqinile inciphisa ukuzama nokuhluleka futhi isekela ukuthuthukiswa kwezendlalelo ezinokubopha okubikezelwayo nokuqina.

Nakuba izingxoxo eziningi zokwelashwa kobuso zigxile kuma-polymers nama-film, izinto zensimbi zidinga izinqubo ezihlukile ukuze kuthuthukiswe ukumelana nokugqwala, ubulukhuni, nokunamathela kukapende. I-anodising yensimbi ye-aluminium ikhiqiza ungqimba lwe-oxide olubuthakathaka oluthuthukisa kakhulu ukubambelela kukapende nokumelana nokuguga, kuyilapho i-phosphating kuyingubo yokuguquka esetshenziswa kakhulu ensimbi ukuze inikeze ungqimba lwe-phosphate oluyikristalu olukhuthaza ukunamathela kwe-primer nokuvikela ukugqwala. I-nitriding ingenisa i-nitrogen ezindaweni zensimbi ukuze kuthuthukiswe ubulukhuni nempilo yokukhathala ngaphandle kokuphazamisa izilinganiso zobukhulu, okuyisinqumo esikhethwayo izingxenye zemishini ezithambekele ekugugeni okunzima. Ukwelashwa kobuso bensimbi engagqwalisi ngokuvamile kudinga i-passivation, i-electropolishing, noma ama-primer akhethekile ngoba ungqimba lwe-passive chromium oxide lungavimbela ukunamathela kukapende ojwayelekile; ukwenza indawo ibe lukhuni ngomshini noma ukwenza kusebenze ngamakhemikhali kulandelwa izinhlelo zokumboza ezifanele kubuyisela ukubopha okuthembekile. Inqubo ngayinye ethize ngensimbi kufanele ikhethwe ngokuhlanganiswa nohlelo lokugcina lokumboza ukuze kunikezwe impilo ehlosekayo nokusebenza okusebenzayo.

Ukuhlanganisa ukwelashwa kwendawo ohlelweni lwekhwalithi yokukhiqiza kufuna izinqubo ezijwayelekile, ukulinganisa njalo, nemijikelezo yempendulo ehlanganisa izilinganiso zendawo nokuhlolwa komkhiqizo wokugcina. Izinqubo zokukhiqiza kufanele zichaze ububanzi obuqondisiwe be-dyne, ukuhluka okwamukelekayo, isikhathi phakathi kokwelashwa nokufakwa, nezenzo ezilungisayo lapho izilinganiso zihlukana khona. Ukulawulwa kwenqubo yezibalo (SPC) kwezinga le-dyne, amandla okukhupha, kanye nokubalwa kweziphazamiso ezibonakalayo kuvumela ukugcinwa okubikezelayo kwemishini yokwelashwa kanye nokuhlaziywa kwezimbangela zokuhluleka kokubambelela. Abahlinzeki abanjengo-广东提力新材料科技有限公司 bangasebenzisane namakhasimende ukuze bahambisane namakhemistri wokufakwa—njengezinhlelo ze-fluorocarbon, PVDF, noma i-epoxy—nezindawo ezilungisiwe, banikeze ukuhlolwa kwamasampula kanye nezivivinyo zokuqala. Le modeli yokubambisana inciphisa ubungozi bokusebenzisa futhi isheshisa isikhathi sokufika emakethe kwemikhiqizo emisha edinga ukulungiswa kwendawo okhethekile.

Ukuze izinkampani zifune ukwenza ngcono ukwelashwa kwendawo, qala ngokuhlolwa kwe-substrate: khomba uhlobo lwe-polymer noma i-metal alloy, izidingo zokumbozwa kwe-downstream, kanye nokuchayeka kwemvelo. Faka izivivinyo zokuqala ezilinganisa amanani e-dyne, wenze i-XPS lapho itholakala, futhi wenze izivivinyo zokunamathela ngemuva kokuqina okugcwele. Uma uthenga izinto zokumboza noma udinga uzakwethu we-ODM, cabanga abakhiqizi abanikeza izixazululo ezihlanganisiwe—ukuhlinzekwa kwezinto, ulwazi lokwelashwa kwendawo, kanye nezinto zokumboza ezenziwe ngendlela eyenziwe ngayo—ukuze wenze ukufaneleka kube lula. I-Guangdong 提力新材料科技有限公司 ihlinzeka ngezinhlobonhlobo zezinto zokumboza zezimboni futhi ingeluleka ngokufanisa izindlela zokwelashwa kwangaphambi kokwelashwa nemikhiqizo ethile; amakhasi abo e-Metal systems kanye ne-Aluminum Tube Coating achaza izinsizakalo ezifanele namakhono emaphrojekthi okuqeda insimbi. Ukuze uthole izinto zokumboza izinkuni nefenisha, izixazululo zabo ze-Pu wood coating kanye ne-Nitrocellulose lacquer zihlanganisa isiqondiso sokulungiswa kwe-substrate okudingekayo ukuze kuqedwe okuhleliwe okuhlala njalo.

Ukwelashwa okuphelele kwendawo kuyisisekelo sokusebenza okuthembekile kwemikhiqizo kuwo wonke amapholima, amafilimu, nezinsimbi. Ukukhetha phakathi kwe-corona, i-flame, i-plasma, noma izendlalelo zokuguqula i-metallurgical kuncike ku-chemistry ye-substrate, amazinga e-dyne adingekayo, kanye nemikhawulo yokukhiqiza. Amathuluzi okulinganisa kusuka ekuhlolweni kwe-dyne kuya ku-XPS avumela ukuthuthukiswa okusekelwe ebufakazini, futhi izindlela zokusebenza ezinciphisa ukulahleka kokwelashwa ziqinisekisa ukungaguquguquki kwesikhathi eside. Ukuhambisa izendlalelo ze-chemistry nezokwelashwa okufanele ngaphambi kokwelashwa—kungakhathaliseki ukuthi i-anodising i-aluminium, i-phosphating insimbi, i-nitriding izingxenye ezisebenzayo, noma ukwelashwa amafilimu epolima—kunikeza izinzuzo ezilinganisekayo ekubambeni, ukuqina, kanye nokwaneliseka kwamakhasimende. Ukubambisana nabaphakeli abanolwazi, njenge-广东提力新材料科技有限公司, kusheshisa ukuxazulula izinkinga futhi kusekele ukuthengwa kwezinhlelo ezifanayo ukuze kutholwe ukusebenza okuphezulu komkhiqizo wokugcina.
