Ukusetyenziswa kwe-Ink yoKhuseleko lokusiNgqongileyo oluSekelwe kuManzi kwiPakethe yoKutya oMfanekiselo

Ukusetyenziswa kwe-Ink yoKhuseleko lokusiNgqongileyo oluSekelwe kuManzi ekuPhakhelweni kokutya

Inkcazelo emfutshane:

Njengohlobo olutsha lokupakisha kunye nezinto zokuprinta, inzuzo enkulu ye-inki esekwe emanzini kukuba ayiqulathanga izinyibilikisi zendalo eziguqukayo.Ukusetyenziswa kwayo kunciphisa inani lezinto eziphilayo eziguquguqukayo (i-VOCs), ayilonakalisi impilo yabavelisi be-inki kunye nabaqhubi bokushicilela, kwaye iphucula umgangatho wokusingqongileyo.Ngoko ke, inokubizwa ngokuba yi-inki ehambelana nokusingqongileyo.Ezona mpawu zinkulu ze-inki esekwe emanzini azikho ungcoliseko lokusingqongileyo, akukho mpembelelo kwimpilo yabantu, akukho kutsha, kunye nokhuseleko olulungileyo.Ayinakunciphisa kuphela i-toxicity eshiyekileyo kumphezulu weemveliso eziprintiweyo, yenza kube lula ukucoca izixhobo zokushicilela, kodwa nokunciphisa umngcipheko womlilo obangelwa ngumbane ongatshintshiyo kunye nezinyibilikisi ezinokutsha.Ukongeza kukhuseleko lokusingqongileyo, iimpawu zokuprinta ze-inki esekelwe emanzini nazo zilungile.I-inki esekelwe emanzini inokusebenza okuzinzile, ayinayo i-plate, ukusebenza okulula, ixabiso eliphantsi, ukunamathela kakuhle emva kokushicilela, ukuchasana kwamanzi okunamandla kunye nokumisa ngokukhawuleza.Iinki ezisekelwe kumanzi azisetyenziswanga kuphela kushicilelo lwe-flexographic kunye noshicilelo lwesikrini esinamandla amakhulu ophuhliso.

Ithemba loPhuhliso kunye neNdlela ye-Ink efumaneka emanzini

I-inki esekwe emanzini ibizwa ngokuba yi-inki esekwe emanzini ngokufutshane.I-flexographic water-based inki ikwabizwa ngokuba yi-liquid inki.Ubukhulu becala yenziwe ngeresin enyibilikayo emanzini, i-organic pigment, isinyibilikisi kunye nezongezelelo ezinxulumeneyo ngokusila.Intlaka emanzi luhlobo olutsha lwesixokelelwano sentlaka esebenzisa amanzi endaweni yesinyibilikisi sezinto eziphilayo njengendawo yokusasazwa.Idityaniswe namanzi ukwenza isisombululo.Emva kokuba amanzi aguquke, ifilimu ye-resin yenziwa.I-resin esekelwe emanzini ayiyona i-resin-based based resin ngokwayo kodwa ifilimu ifilimu efunyenwe emva kokuguqulwa kwamanzi.I-polyurethane yamanzi, njengommeli, inokusetyenziswa ngokubanzi kwiingubo, i-adhesives, i-coating cloth kunye ne-ejenti zokugqiba, ii-agent zokugqiba ngesikhumba, ii-agent zonyango zephepha kunye ne-fiber surface treatment agents.I-inki esekelwe ngamanzi ilungele ngokukodwa ukutya, isiselo, iyeza, icuba, iwayini, izinto zokudlala zabantwana kunye nezinye iimveliso zokupakisha kunye nokushicilela kunye neemfuno ezingqongqo zococeko, ukubuyisela imveliso esekelwe kwi-solvent kwiinkalo ezahlukeneyo.Njengenye yezinto ezintlanu zokuprinta, i-inki esekwe emanzini idlala indima ebalulekileyo kwinkqubo yoshicilelo kunye nomgangatho wokushicilela.Ulwabiwo olufanelekileyo lwe-inki likhonkco elibalulekileyo lokuqinisekisa umgangatho weemveliso eziprintiweyo.I-inki esekelwe emanzini iye yathatha inxaxheba enkulu ekushicileleni i-flexographic ngenxa yeenzuzo zayo zokukhuselwa kwendalo kunye noqoqosho.
Uphuhliso oluluqilima loshishino loshicilelo lokupakisha oluluhlaza luya kuqinisa ukhuphiswano kwimarike yeinki yoshicilelo lwe-offset.Ngoku abavelisi be-inki bathumele umqondiso wokuba iindleko ze-inki zezinto eziluhlaza ziye zaphakama ngokukhawuleza, okuya kwandisa ngakumbi iindleko zokuvelisa kunye nokusebenza ngokulula.Oku kubangelwe ikakhulu kukunqongophala kwehlabathi kothotho lweearhente zeekhemikhali, ezizezona zinto ziphambili ekuvelisweni kweinki.Ukuza kuthi ga ngoku, ukunyuka kwexabiso leoli ekrwada kunye ne-petrochemical derivatives sesona sizathu sokunyuka kwamaxabiso e-inki.Nangona kunjalo, nokuba ixabiso leoli liyehla, kuba ishishini le-inki lihlaselwa kukunqongophala kweekhemikhali zezinto eziluhlaza, ngokukodwa izinto eziluhlaza ezifana ne-nitrocellulose, i-acrylic acid, i-acetic acid kunye ne-titanium dioxide, ixabiso le-inki liya kunyuka kuphela.Okwangoku, amazwe aphuhlileyo kunye nemimandla izama ukuphuhlisa nokusebenzisa i-inki ukubuyisela ngokuthe ngcembe inki ye-solvent.Ukupakisha ukuprinta ngoshicilelo lwe-inki esekwe emanzini njengeyona nto iphambili yophuhliso yenze umkhwa kwihlabathi.

Iimpawu zoLwakhiwo lwe-Inki esekwe emanzini: Umahluko phakathi kwe-Agent kunye ne-Oli esekwe kwi-Ink.

Umgangatho we-polyurethane we-inki ikakhulu usebenzisa i-aliphatic polyester kunye ne-aliphatic isocyanate njengezona zinto zibalulekileyo zokwenziwa kwinkqubo yokulungiselela.Xa kuthelekiswa ne-polyurethane enuka kamnandi, eyokuqala inozinzo olugqwesileyo ngakumbi kwaye ifilimu emva kokwenziwa kwefilimu inokumelana nokutyheli ngcono.Kukho amaqela amhlophe afana ne-carbamate, i-urethane, i-ester bond kunye ne-ether bond kwicandelo le-polyurethane molecular chain ye-inki, eyenza i-hydrogen bond kunye namaqela e-polar kumphezulu we-polar substrates ezahlukeneyo ezifana ne-pet kunye ne-PA, ngaloo ndlela zenza idibaniso kunye amandla athile oqhagamshelwano.Emva kokuba i-polyurethane resin elungisiweyo yenziwe nge-inki, inokuprintwa kumphezulu we-polar substrate yeplastiki kunye nokukhawuleza ukunamathela okulungileyo.I-polyurethane resin ye-inki ilungiswa ngokubanzi ukusuka kwi-polyester okanye i-polyether polyol, i-ester ring diisocyanate kunye ne-diamine chain extender.Ngenxa yokuqaliswa kwebhondi ye-urea kwi-polyurethane resin, i-polyurethane urea resin (PUU) yenziwe, enezinto ezintle zokumanzisa kunye nokusabalalisa kwi-pigment.
I-polyurethane resin ye-inki inokuhambelana kakuhle kunye ne-aldehyde ketone resin, i-chloroacetic resin, njl.I-polyurethane resin ye-inki ilungiswa ngokuzisa iqela le-urea kwicandelo le-polyurethane ye-molecular yendabuko, ephucula kakhulu amandla okubambisana kunye nepropathi yokwenza ifilimu ye-resin ngokwayo.I-resin ye-polyurethane yendabuko inoluhlu olubanzi lwe-miscibility kunye ne-organic solvents.Noko ke, kwinkqubo yokulungiselela inki, ukuze kulungiswe fluidity kunye viscosity inki, kuyimfuneko ukongeza izinyibilikisi utywala organic, nto leyo eya kunciphisa kakhulu uzinzo inkqubo resin kwaye kubangele turbidity, imvula flocculent kunye nezinye iziganeko zemveli. i-polyurethane resin.Kwicandelo le-molecular chain ye-polyurethane resin yokuprinta inki, ngenxa yobukho beqela le-urea, i-polyurethane resin kunye notywala inokuchithwa.Nangona kunjalo, kufuneka kuqatshelwe ukuba i-solvent yotywala iseyi-solvent ye-pseudo.Kwimeko ye-microscopic, isinyibilikisi sotywala sigquma kuphela imolekyuli yentlaka ye-polyurethane, endaweni yokungena kwi-molecular polarity kwi-molecule efana ne-solvent yokwenyani, ukuze i-inki elungiselelwe nge-polyurethane resin ibe nokumanzi okulungileyo.
Umahluko omkhulu phakathi kwe-inki esekelwe emanzini kunye ne-oyile-based inki yi-solvent.I-inki esekwe emanzini isebenzisa amanzi (45% - 50%) njengesinyibilikisi, kunye nomxholo weVOC ophantsi kakhulu kunye nongcoliseko oluncinci lokusingqongileyo;I-inki enamafutha isebenzisa i-solvents ye-organic (i-toluene, i-xylene, i-alcohol alcohol, njl.) njengesinyibilikisi.I-inki esekelwe emanzini isebenzisa i-solvent yamanzi kunye ne-soluble yamanzi njengezona nxalenye eziphambili zesiseko sombala onyibilikileyo;Kukho kwakhona inki yedayi kunye ne-pigment inki kwi-inki esekwe emanzini, kwaye i-pH ingathathi hlangothi ngokubanzi;I-oyile nayo ine-inki yedayi kunye ne-pigment inki, kwaye i-pH idla ngokuba neasidi.I-inki esekelwe ngamanzi kunye ne-oyile-based inki ayinakuxutywa kwintloko yokushicilela efanayo.
Kwi-inki esekelwe emanzini, i-resin esekelwe emanzini yinto ebalulekileyo ye-inki esekelwe emanzini.I-inki yokudibanisa izinto ichaphazela ngokuthe ngqo ukusebenza kokunamathela, isantya sokumisa, ukusebenza kwe-anti fouling kunye nokumelana nobushushu be-inki, kwaye kuchaphazela nokusebenza kweglosi kunye ne-inki yokudlulisa.Ngoko ke, ukukhethwa kwe-resin efanelekileyo yamanzi kuyisitshixo sokulungiswa kwe-inki yamanzi.Kufuneka ibe nobudlelwane obuhle kunye nemibala, ukunamathela okuphezulu emva kokushicilela kunye nokwakheka kwefilimu, ukuxhathisa ukunxiba, ukumelana nokuqala, ukumelana nobushushu obuhle, ukuwela ngokulula kunye nokwakheka kwefilimu.Iintlaka ezisetyenziswa ngokuqhelekileyo emanzini ziquka i-polyurethane resin yamanzi, i-acrylic resin, i-polyvinyl alcohol kunye ne-epoxy resin.
I-polyurethane resin yasemanzini isasazwa emanzini ngokuzisa amaqela e-hydrophilic kwitsheyina le-polyurethane molecular.I-polyurethane resin yamanzi ineenzuzo zokusetyenziswa okulula, ukusebenza okuzinzileyo, ukunamathela okuqinileyo, i-gloss ephezulu kunye nokumelana nokushisa okulungileyo.Inokufaneleka kwiindlela ezahlukeneyo zokushicilela, ngakumbi ukuprintwa kwesikrini, iibhokisi zokupakisha zeplastiki kunye neefilimu ezidibeneyo.
