Unyango loMphezulu woShicilelo lweWebhu emxinwa: Iindlela eziBalulekileyo zokuphucula ukuncamathela kwe-Ink
Iindlela zonyango ezikumgangatho ophezulu zibalulekile ekufumaneni umgangatho woshicilelo olukhethekileyo kunye nokuqina kwipakethe ebhetyebhetye, iilebhile, kunye nosetyenziso olukhethekileyo, ngokweengcali zeshishini.
Ukuphumeza i-inki egqibeleleyo kwaye ende{0}ehlala ixesha elide iseyingxaki enkulu kukhuphiswano kunye nomgangatho{1}umhlaba oqhutywayo woshicilelo lwewebhu olumxinwa. Ukuze woyise amandla asezantsi eenxalenye ezinje nge-polyethylene, i-polypropylene, kunye nezinye iiplastiki, iingcali zeshishini zihlala zikhangela izisombululo ezintsonkothileyo ezimxinwa zoshicilelo lwewebhu. Olu shicilelo lweendaba luphonononga ubugcisa obuqinisekisa ubomi obude bokushicilela, ukushukuma, kunye nokusebenza kweelebhile, ukupakishwa okuguquguqukayo, kunye nezinto ezizodwa, kunye nezicwangciso ezisisiseko zokuphucula ukubambelela kwe-inki.
Kwiwebhu emxinwa, unyango olusebenzayo lomphezulu alukho nje isigaba kwinkqubo; sisitshixo sokushicilela ngempumelelo. Inesiphumo esikhawulezileyo kwinkangeleko yemveliso, isibheno seshelufu, kunye neempawu eziluncedo ezibandakanya ukuxhathisa imichiza kunye ne-scuff.
UMsebenzi waMandla oMphezulu oBalulekileyo kwi-Ink Adhesion
Amandla angaphezulu alele entliziyweni yomngeni wokuncamathela. Kuba iifoyile zepolymer kunye neefilim zihlala zinamandla asezantsi kumphezulu, aziyi{1}}zineziqhushumbisi kwaye azingeneli ngokwekhemikhali. Ukumanzisa kakubi kungumphumo walo mqobo, owenza ii-inki, iileyiti, izinto zokuncamathelisa zibe ngamaso endaweni yokuba zisasazeke ngokufanayo kwaye zibotshwe. Ukuguqula le ndawo ye-substrate kwinqanaba le-molecular ukwenzela ukwandisa amandla ayo angaphezulu kunye nokudala iziza ezisebenzayo zokusebenzisana kweekhemikhali yinjongo ephambili yalo naluphi na unyango olumxinwa lwewebhu. Le nkqubo ibalulekile ekwandiseni umgangatho woshicilelo kwiifilim eziguquguqukayo kunye nokuqinisekisa ukuthotyelwa kwe-inki okuphuculweyo.
Iindlela eziBalulekileyo zokuCoca uMphezulu woShicilelo lweWebhu olumxinwa
Iintlobo ngeentlobo zetekhnoloji ezithembekileyo ziyafumaneka kubaguquli bewebhu banamhlanje. I-substrate, ulungelelwaniso locinezela, isantya, kunye nesiphumo esicetywayo zonke zinefuthe kukhetho lobuchule.
Umgangatho woShishino woNyango lweCorona
Kushicilelo lwewebhu olumxinwa, unyango lokukhutshwa kwe-corona iseyeyona ndlela idumileyo. Isebenza ngokwenza -ukukhutshwa kombane okuphezulu phakathi kwerola ephantsi yedielectric kunye ne-electrode. Ngenxa yoko, umoya u-ionized, uvelisa i-plasma ebetha i-substrate surface. Ukongeza ekupheliseni ungcoliseko lwendalo, le bombardment yongeza amaqela asebenzayo epolar{4}}afana neehydroxyls kunye neecarbonyls{5}}kwikhonkco lepolymer. Amandla omphezulu we-substrate anda kakhulu yile nkqubo yokuxutywa, eyenza ukuba i-inki{7} iphendule. Ukongeza ekuboneleleni ngolawulo oluchanekileyo lwamandla, iinkqubo zonyango lwe-corona yangoku zixabiswa ngenxa yokukwazi kwabo ukudibanisa emgceni kunye nokusebenza kakuhle ngezinto ezahlukeneyo.
Unyango lwePlasma: Iphucukile kwaye ichanekile
Nangona i-corona luhlobo lwe-plasma ye-atmospheric, utshintsho olulawulwayo kunye noluhambelanayo lunikezelwa ngezixhobo ezikhethekileyo zonyango lwe-plasma (ngokuqhelekileyo kuxinzelelo oluphantsi okanye ngeegesi ezikhethekileyo). Amanqanaba aphezulu okusebenza komphezulu anokuphunyezwa ngale ndlela ngaphandle kokwenza umngcipheko wonyango olugqithisileyo, okwenzeka ngamaxesha athile nge-corona. Isebenza ngokukodwa kumacandelo e-3D antsonkothileyo, izixhobo zonyango, kunye nezixhobo ezibuthathaka kubushushu. Ukusebenza komphezulu wePlasma sisisombululo esiphezulu kwimiba yokuncamathela ye-inki kwiindawo eziphezulu{4}}ezifuna elona nqanaba liphezulu lokuthembeka kokuncamathelisa.
Unyango lomlilo: Lumelele kwizinto ezikhethekileyo
Enye indlela enamandla ye-thermal oxidation kunyango lomlilo. I-substrate web ihamba phezu kwebhanki yesitshisi, apho ilangatye elilawulwa ngononophelo liguqula umphezulu wekhemistri ngokudibanisa -iradical kunye neenkqubo zobushushu ezisimahla. Isebenza ngokumangalisayo kwi-polyolefins kwaye isetyenziswa rhoqo kwiifilimu ezishinyeneyo, izikhongozeli, kunye neemeko ezifuna uhlengahlengiso oluhlala ixesha elide, olude{3}}lomphezulu. Kubalulekile ekuphuculeni ukubambelela kwe-inki kwiifilim zeplastiki ngenxa yesakhono sazo sokubonelela ngobunzulu kunye nokuvuselela umphezulu ozinzileyo.
Unyango lwangaphambili-lonyango kunye ne-primer coatings
Ngamanye amaxesha kusetyenziswa i-liquid primer okanye-unyango lwangaphambili lwekhemikhali, ingakumbi kwii-substrates ekunzima ukuprinta kuzo okanye kwii-inks ezisebenzayo (ezifana ne-conductive inki). Ezi zaleko zinika amandla{2}}aphezulu, umaleko wojongano olulungiselelweyo oluququzelela i-inki iankile ephezulu. Kwezinye{4}}iipholima zamandla ezisezantsi, apho unyango lwe-corona oluthe ngqo lusenokungoneli, obu buchule bubalulekile ekwandiseni ukubambelela kwe-inki ye-UV.
Ukuphucula unyango lokuZinza kunye nokuSebenza
Ukuphucula kubalulekile ukongeza kukhetho lobuchule. Ukungaguquguquki kuqinisekiswa ngokusebenzisa iipeni ze-dyne okanye abavavanyi be-intanethi ukujonga amandla angaphezulu aphathwayo. Iinkqubo ezibonelela ngobuchule obukhulu{2}}ngokuphatha ngokufanelekileyo kwizantya zoshicilelo olukhulu ngelixa zisebenzisa amandla amancinci{3}}ziintsingiselo yoshishino. Ukongeza, ngokuphucula ukuhanjiswa kunye nokugubungela, unyango olufanelekileyo lomphezulu lunokunciphisa ukusetyenziswa kwe-inki kunye nokukhuthaza iindlela zokushicilela ezihambelana nokusingqongileyo ngokunciphisa inkunkuma. Isiphumo sokusingqongileyo kunye nokusebenza kakuhle kokuprintwa kweelebhile kuchaphazeleka ngokuthe ngqo ngokugxininisa ekukhuthazeni ukunamathela ngonyango oluphuculweyo.
Ikamva: Ubuchwephesha obukrelekrele kunye noManyano
Iisistim ezikrelekrele, ezidityanisiweyo ziyindlela yexesha elizayo yonyango olumxinwa lomphezulu woshicilelo lwewebhu. Lindela uphuhliso olungakumbi kwiiyunithi ze-corona ezitywiniweyo, ezinamagumbi okwandisa ukusebenza kakuhle kunye nokunciphisa imveliso ye-ozone. Ukudityaniswa kwenkqubo yolawulo lweendaba kuya kwenza ulungelelwaniso lwamandla oluzenzekelayo olusekelwe kwi-substrate kunye nesantya, ukuqinisekisa amanqanaba afanelekileyo onyango kunye nokubandakanyeka komsebenzisi omncinci. Ukwenziwa kwezinto ezintsha kuzakuphenjelelwa kukhangelo lwezicwangciso eziliqili ezibalulekileyo zokuphucula ukubambelela kwe-inki, ingakumbi kwibhayoloji entsha ephuhlisiwe{3}ebhanyabhanya esele isetyenzisiwe eveza imiba entsha yokuncamathela.
Ngokufutshane
Ukuqukumbela, abaguquli abazabalazela umgangatho abanako ukuyekelela ekulawuleni unyango lomphezulu wewebhu emxinwa. Ezi ndlela, ezisusela kunyango lwe-corona olusetyenziswa ngokubanzi ukuya kwi-plasma entsonkothileyo yokusebenza komphezulu, ngamagorha afihliweyo anika iilebhile kwaye apakishe imbonakalo yawo{1}}ehlala ixesha elide, enemibala. Abashicileli banokusombulula iingxaki zokuncamathela, bavule amathuba amatsha ezicelo, kwaye banike abathengi babo{3}}umgangatho ophezulu, iimveliso ezithembekileyo ngokuqonda kunye nokusebenzisa iindlela ezingundoqo ezifanelekileyo zokuphucula ukubambelela kwe-inki. Utyalo-mali oluqhubekayo kunye nobuchule kunyango lomphezulu luya kuqhubeka luyinzuzo ecacileyo yokhuphiswano kwicandelo lewebhu elimxinwa njengoko utshintsho lwe-substrates kunye neemfuno zokushicilela ziba nzima ngakumbi.
