Upenyu hwedu hwakazadzwa nezvinhu zvakasiyana-siyana zvakadhindwa, zvipfeko, magazini, uye kurongedzerwa kwemarudzi ose.Sezvo chikafu chiputiriso vatengesi nevatengi, isu tinonyanya kunetseka kuti ndeupi rudzi rweinki inonyanya kuenderana nemamiriro ekunze uye yakakodzera indasitiri yekurongedza chikafu.Muchikamu chino, tichakuzivisai kune inki inochengetedza zvakatipoteredza inonyatsokodzera kudhindwa kwechikafu chekuisa: mvura-based inki.
Pfungwa yeInk Inobva Mvura
Nzira yesainzi inoshandiswa kugadzira iyi inodaidzwa kuti inki yemvura, iyo inonyanya kushandisa mvura sechinhu chinonyungudutsa.Ingi inogadzirwa nemvura uye dzimwe ingi dzinodhinda hadzina chinokuvadza pautano hweanodhinda muchina kana zvichienzaniswa nedzisina kuvhurika, dzine chepfu organic solvents.Iyo inodhinda zvakare ine ushamwari kwezvakatipoteredza.Iyo inki haina kungova nezvinhu zvisingabatike chete, asi zvakare inobvisa kutyisidzira kwakavanzika kwekupisa uye kuputika mumusangano wekudhinda, izvo zvakanaka kuti zvishande zvakachengeteka.Ehe, ingi neingi zvino zvine maapplication akasiyana-siyana: ingi yekudhinda, ingi yeprintographic, neingi yekudhinda gravure. MuEurope, America, Japan, nedzimwe nyika dzakabudirira, ingi yakaramba ichitsiva ingi, pamwe nekudhinda kweoffset kunze Ingi yakasiyana nedzimwe nzira dzokudhinda.MuUnited States, semuenzaniso, 95% yeflexographic prints uye 80% yegravure prints ine inki.
Pamusoro pekuchengetedzwa kwezvakatipoteredza, inoshandiswa zvakanyanya munyika yeinki yemvura nekuda kwekuita kwayo kwepamusoro: inki kugadzikana kwemavara, kupenya kwepamusoro, simba remavara rakasimba, ndiro isingaparadzi, kunamatira kwakasimba mushure mekudhindwa, kukurumidza kuomeswa kwemvura, kushomeka kwemvura. , kudhinda kwemavara mana, kudhinda kwemavara, zvichingodaro.Kuvandudza ingi yemvura uye kushandiswa muChina kwakatanga nguva yapera, asi kufambira mberi kwakakurumidza, kunyanya mumakore achangopfuura, izvo zvakawedzera mwero wekukura nekukurumidza.Hunhu hweingi yemumba hwawedzera tandem pamwe nekuwedzera kwekudiwa kweinki.Ingi, mupfungwa yechinyakare yokuomesa zvishoma nezvishoma, kupenya kusina kujeka, kushaikwa kwekudzivirira mvura, kudhinda kwenhema, uye kumwe kukanganisa, yakagadziridzwa zvikuru.Mitengo yeinki inotengwa kunze kwenyika yakakwira zvakanyanya, asi ingi yekuChina yave kutora musika nemagadzirirwo ayo akanaka uye anokwanisika. Mitengo yeinki inotengwa kunze kwenyika inowanzokwira, asi ingi yekuChina yave kutora musika nemagadzirirwo ayo akanaka uye anokwanisika.
Funga nezveZvinhu uye Kuumbwa kweInk-Yakavakirwa Mvura.
Ingi inonyungudika mumvura inoumbwa neresin inonyungudika mumvura, pigment yakaoma, zvinonyungudutsa, uye zvinowedzerwa zvakavezwa nesainzi.Mvura-soluble resin in ingi inonyanya kushanda sechinhu chinobatanidza, ichiparadzira pigment particles zvakafanana kuitira kuti ingi ine imwe nzira yekufamba uye inonamatira kune substrate zvinhu kuitira kuti ingi inogona kuumba yunifomu yefirimu yakatsetseka mushure mekudhinda.Rudzi rweinki runonyanya kutsanangurwa nepigment, iyo inoparadzirwa zvakaenzana mukubatanidza zvinhu sezvidimbu, uye pigment particles zvinogona kutora, kuratidzira, kukanganisa, uye kutumira chiedza, zvichivabvumira kuratidza rumwe ruvara. pigment inofanira kuva neruvara rwakajeka, ruvara rwakakwana uye simba rekuvhara, uye kupararira kwepamusoro.Uyezve, zvichienderana nekushandiswa, vanogona kuve nekusiyana kweabrasion resistances.Basa rekunyungudutsa nderekunyungudutsa resin kuitira kuti inki ive nehumwe fluidity, kuendesa kunogona kuitika zvakanaka mukati mekudhinda, uye viscosity uye kuomesa kuita kweinki kunogona kuchinjwa.Iyo inonyungudutsa mumvura-based inki inonyanya kuve mvura ine zvishoma ethanol.
Mvura-Yakavakirwa Ink Inowanzo Kushandisa Zvinowedzera Zvakadai seDefoamer, PH Value Stabilizer, Slow Drying Agent, uye So On.
(1) defoamer.Basa re defoamer nderokudzivisa uye kubvisa chizvarwa chemhepo inoputika.Kazhinji, kana viscosity yeinki yemvura yakakwira zvakanyanya, kukosha kwePH kwakadzikira, kana kumhanya kwemuchina wekudhinda kuri kukurumidza, zviri nyore kugadzira mabhuru.Kana huwandu hwemabhuru anogadzirwa akakura, pachava nekudonha kwemavara machena, asina kuenzana inki, izvo zvinozokanganisa kunaka kwechinhu chakadhindwa.
(2) chinononoka kuomesa agent.A anononoka kuomesa agent anogona kurambidza uye kunonoka kuomeswa kwemvura-based inki kudzivirira iyo inki mupureti yekudhinda kana anilox rollers kubva pakuomeswa uye kuderedza chiitiko chekuvharira nekunamira kukanganisa kudhinda.Dzora huwandu hweanononoka kuomesa agent;kazhinji, huwandu hweinki hunofanira kuva pakati pe1% ne2%.Kana iwe ukawedzera zvakanyanya, iyo inki haizooma zvakakwana, uye iyo inodhinda ichave yakanamatira, yakasviba, kana kuburitsa kunhuhwirira kwakashata.
(3) PH kukosha kwekusimbisa:PH value stabilizer inonyanya kushandiswa kugadzirisa uye kutonga kukosha kwePH yeinki-based inki kuitira kuti igadzikane muhuwandu hwe8.0-9.5.Panguva imwecheteyo, inogona zvakare kudzora viscosity yemvura-based inki uye inki dilution.Kazhinji, huwandu hwakakodzera hwePH stabilizer hunofanirwa kuwedzerwa imwe neimwe nguva muchirongwa chekudhinda kuchengetedza ingi yemvura iri muchimiro chakanaka chekudhinda.
Ushamwari hwezvakatipoteredza hwemvura-based inki
Ingi yemvura inosangana nezvinodiwa zvekuchengetedza kwezvakatipoteredza, chigadzirwa chine huturu husina chepfu, husingaparadzi, husingagumbure, hahupisi, husingaputike, hune kuchengetedzwa kwakanaka, huri nyore kutakura, hune huwandu hwakanyanya, hushoma. chipimo chemushonga, yakaderera viscosity, yakanaka kuchinjika kudhinda, kuita kwakadzikama, kukurumidza kukurumidza kuomerera, kuomesa nekukurumidza, mvura, alkali, uye abrasion resistance performance zvakanakisa;Kudhinda maitiro akaoma kunogonawo kuwana mazinga akapfuma, mavara akajeka uye akakwirira-kupenya, uye humwe hunhu.Kubatsira kukuru kwekushandisa mvura-based inki ndeyokuti inoderedza kuwanda kwehupenyu hunoputika (voc) hunobudiswa mumhepo, iyo inobatsira kuvandudza. kudhinda mamiriro, kudzivirira kusvibiswa kwemhepo, uye kuderedza zvakanyanya njodzi yemoto.Kuti uvandudze huwandu hwemamiriro ekunze, inogona kubvisa zvachose zvimwe zvinokuvadza izvo inks-based inki dzine hutano hwevanhu, pamwe nekusvibiswa kunouya nekurongedza.Inoshanda zvakanyanya mukudhinda nekurongedza zvinhu izvo zvinoda kuchengetwa zvine utsanana, zvakadai sezvokudya nemishonga.
Semutengesi wemukombe wemapepa, GFP yagara yakazvipira kushandisa eco-inoshamwaridzika zvinhu muzvinhu zvayo, ichitora mutoro wezvese nharaunda uye hutano hwevatengi vayo.Makapu edu emapepa anodhindwa achishandisa ingi dzemvura, uye kudhinda kunoitwa makapu asati aiswa laminated, saka kana ashandiswa, inki kubva kunze haizokwikwi kumadziro emukati emukombe, zvichiwedzera kuchengetedza hutano hwe. vashandisi.Ndokumbira ushanyire chinongedzo chinotevera kuti uwane zvimwe nezve yedu yakatenderedza mapepa makapu uye zvine hukama maapplication.
