Ubomi bethu buzaliswe zizinto ezahlukeneyo ezishicilelweyo, impahla, iimagazini, kunye neepakeji zazo zonke iintlobo. Njengabathengisi bokupakisha ukutya ngobuninzi kunye nabathengi, sixhalabile kakhulu malunga nokuba loluphi uhlobo lwe-inki olunobuhlobo nokusingqongileyo kwaye lufaneleke ngakumbi kushishino lokupakisha ukutya. Kweli nqaku, siza kukwazisa nge-inki enobuhlobo nokusingqongileyo efanelekileyo ngakumbi yokuprinta ukupakisha ukutya: i-inki esekelwe emanzini.
Ingcamango ye-inki esekelwe emanzini
Inkqubo yesayensi isetyenziswa ukwenza le inki ibizwa ngokuba yi-water-based, esebenzisa kakhulu amanzi njengesinyibilikisi. I-inki esekwe emanzini kunye nezinye ii-inki zokuprinta azinampembelelo imbi kwimpilo yomqhubi womatshini wokuprinta xa kuthelekiswa nezinyibilikisi zazo zendalo ezingonakalisiyo, ezinetyhefu. Ushicilelo lukwanobuhlobo nokusingqongileyo. I-inki ayinazo nje kuphela iipropati ezingatshiyo, kodwa ikwasusa nosongelo olufihlakeleyo lokuba ingatsha kwaye iqhume kwindawo yokuprinta, nto leyo eluncedo ekusebenzeni ngokukhuselekileyo. Kakade ke, i-inki kunye ne-inki ngoku zinezicelo ezahlukeneyo: i-inki yokuprinta ye-offset, i-inki yokuprinta ye-flexographic, kunye ne-inki yokuprinta ye-gravure. EYurophu, eMelika, eJapan, nakwamanye amazwe aphuhlileyo, i-inki iye yathatha indawo ye-inki ngokuthe chu, kunye nokuprinta kwe-offset ngaphandle kwezinye iindlela zokuprinta ze-inki ezikhethekileyo. E-United States, umzekelo, i-95% yeeprinti ze-flexographic kunye ne-80% yeeprinti ze-gravure ziqulethe i-inki.
Ukongeza kukhuseleko lokusingqongileyo, isetyenziswa kakhulu kwihlabathi le-inki yamanzi ngenxa yokusebenza kwayo okuphezulu: uzinzo lombala we-inki, ukukhanya okuphezulu, amandla ombala aqinileyo, ipleyiti engaboliyo, ukunamathela okunamandla emva kokuprinta, isantya sokomisa esihlengahlengiswayo, ukumelana namanzi, ukuprinta okungaphezulu kwemibala emine, ukuprinta ngemibala egqamileyo, njl. Uphuhliso kunye nokusetyenziswa kwe-inki yamanzi eTshayina kwaqala kade, kodwa inkqubela phambili ibe ngokukhawuleza, ngakumbi kwiminyaka yakutshanje, nto leyo eye yandisa izinga lophuhliso olukhawulezayo. Umgangatho we-inki yasekhaya unyuke kunye nokwanda kwemfuno ye-inki. I-inki, ngokwesiko lokomisa kancinci, ukukhazimla okubi, ukungabikho kokumelana namanzi, ukuprinta okungeyonyani, kunye nezinye iimpazamo, iphuculwe kakhulu. Amaxabiso e-inki engeniswe kwamanye amazwe adla ngokuba phezulu kakhulu, kodwa i-inki yaseTshayina ibisoloko ithatha indawo yemarike ngoyilo lwayo oluhle nolufikelelekayo. Amaxabiso e-inki engeniswe kwamanye amazwe adla ngokuba phezulu kakhulu, kodwa i-inki yaseTshayina ibisoloko ithatha indawo yemarike ngoyilo lwayo oluhle nolufikelelekayo.
Cinga ngeeMpawu kunye noBume be-Ink esekwe emanzini.
I-inki esekwe emanzini yenziwe yi-resin enyibilikayo emanzini, ii-pigment ezintsonkothileyo, izinyibilikisi, kunye nezongezo eziye zacolwa yinkqubo yesayensi yokudibanisa. I-resin enyibilikayo emanzini kwi-inki isebenza ngokuyintloko njengento edibanisayo, isasaza amasuntswana e-pigment ngokulinganayo ukuze i-inki ibe nokuhamba okuthile kwaye inamathele kwizinto ezikwi-substrate ukuze i-inki yenze umaleko wefilimu ofanayo emva kokuprinta. Umbala we-inki umiselwa kakhulu yi-pigment, esasazwa ngokulinganayo kwizinto ezidibanisayo njengamasuntswana, kwaye amasuntswana e-pigment anokufunxa, abonakalise, akhanye, kwaye adlulisele ukukhanya, okuwavumela ukuba abonise umbala othile. Ngokubanzi, i-pigment kufuneka ibe nombala ocacileyo, umbala owaneleyo kunye namandla okugubungela, kunye nokusasazeka okuphezulu. Ngaphezu koko, kuxhomekeke ekusetyenzisweni, zinokuba nokumelana okuhlukeneyo kokukrweleka. Umsebenzi we-solvent kukunyibilikisa i-resin ukuze i-inki ibe nokuchaneka okuthile, ukudluliselwa kungenzeki kakuhle kuyo yonke inkqubo yokuprinta, kwaye ukusebenza kwe-viscosity kunye nokomisa kwe-inki kunokuguqulwa. I-solvent kwi-inki esekwe emanzini ngokuyintloko ngamanzi ane-ethanol encinci.
I-inki Esekelwe Emanzini Idla Ngokusebenzisa Izongezo Ezinjalo njenge-Defoamer, i-PH Value Stabilizer, i-Slow Drying Agent, njl.
(1) isixhobo sokucoca ifoam. Indima ye-defoamer kukuthintela nokuphelisa ukuveliswa kwamaqamza omoya. Ngokubanzi, xa i-viscosity ye-inki esekwe emanzini iphezulu kakhulu, ixabiso le-PH liphantsi kakhulu, okanye isantya sokusebenza komatshini wokuprinta sikhawuleza kakhulu, kulula ukuvelisa amaqamza. Ukuba inani lamaqamza aveliswayo likhulu kakhulu, kuya kubakho ukuvuza kombala we-inki omhlophe, ongalinganiyo, nto leyo eya kuchaphazela ngokuqinisekileyo umgangatho wento eprintiweyo.
(2) iarhente yokomisa kancinci.I-arhente yokomisa kancinci inokuthintela kwaye inciphise isantya sokomisa se-inki esekwe emanzini ukuthintela i-inki ekwipleyiti yokuprinta okanye ii-anilox rollers ukuba yome kwaye inciphise ukwenzeka kwempazamo zokuprinta ezivimbayo nezincamathiselayo. Lawula ubungakanani be-arhente yokomisa kancinci; ngokubanzi, isixa siphela se-inki kufuneka sibe phakathi kwe-1% kunye ne-2%. Ukuba wongeza kakhulu, i-inki ayizukoma kakuhle, kwaye ushicilelo luya kuba ncamathela, lungcolile, okanye luvelise ivumba elibi.
(3) Isiqinisi sexabiso le-PH:Isiqinisi sexabiso le-PH sisetyenziswa kakhulu ukulawula nokulawula ixabiso le-PH le-inki esekwe emanzini ukuze ihlale ikwi-8.0–9.5. Kwangaxeshanye, inokulawula nokuqina kwe-inki esekwe emanzini kunye nokuxuba i-inki. Ngokubanzi, kufuneka kongezwe isixa esifanelekileyo se-PH stabilizer rhoqo ngexesha elithile kwinkqubo yokuprinta ukuze igcine i-inki esekwe emanzini ikwimeko entle yokuprinta.
Ubuhlobo nokusingqongileyo be-inki esekwe emanzini
I-inki esekwe emanzini ihlangabezana neemfuno zokhuseleko lokusingqongileyo, imveliso inevumba elingenabungozi, aliboliyo, alicaphukisi, aliqhumi, likhuselekile, kulula ukulithutha, linoxinzelelo oluphezulu, idosi ephantsi, i-viscosity ephantsi, liyakwazi ukuguquguquka xa liprintwa, lisebenza kakuhle, likhawuleza xa linamathela, loma ngokukhawuleza, lisebenza kakuhle emanzini, li-alkali, kwaye liyakwazi ukumelana nokukrala; Iipateni ezintsonkothileyo zokuprinta zinokufikelela kumanqanaba atyebileyo, imibala eqaqambileyo nekhazimlayo, kunye nezinye iimpawu. Inzuzo ephambili yokusebenzisa i-inki esekwe emanzini kukuba inciphisa inani le-organic volatiles (voc) ekhutshwa emoyeni, nto leyo enceda ekuphuculeni iimeko zokuprinta, kuthintelwe ungcoliseko lomoya, kwaye inciphise kakhulu umngcipheko womlilo. Ukuze kuphuculwe umgangatho jikelele wokusingqongileyo, inokususa ngokupheleleyo ezinye zezinto eziyingozi ezinazo ii-inki ezisekwe kwisinyibilikisi kwimpilo yabantu, kunye nongcoliseko oluza nokupakishwa. Isebenza kakuhle kakhulu ekuprinteni nasekupakisheni iimpahla ekufuneka zigcinwe zicocekile, njengokutya namayeza.
Njengomthengisi weekomityi zephepha ngobuninzi, i-GFP ibisoloko izibophelele ekusebenziseni izinto ezinobuhlobo nokusingqongileyo kwiimpahla zayo, ithatha uxanduva lokusingqongileyo kunye nempilo yabathengi bayo. Iikomityi zethu zephepha ziprintwa kusetyenziswa ii-inki ezisekelwe emanzini, kwaye inkqubo yokuprinta yenziwa ngaphambi kokuba iikomityi zifakwe i-laminate, ngoko ke xa zisetyenziswa, i-inki evela ngaphandle ayizukugudla eludongeni lwangaphakathi lwekomityi, nto leyo ekhusela impilo yabasebenzisi. Nceda undwendwele eli khonkco lilandelayo ukuze ufumane okungakumbi malunga neekomityi zethu zephepha ezinobuhlobo nokusingqongileyo kunye nezicelo ezinxulumene noko.
