Hunhu uye hunyanzvi hwekudhinda kweinki yemvura-yakavakirwa pamapepa ane makorachocolate box
Mvura-based inki inyanzvi yeinki inochengetedza zvakatipoteredza iyo yakagamuchira kutarisa kwakapararira mumakore achangopfuurabhokisi repastry. Ndeupi musiyano uripo pakati peinki yemvura neingi inodhindawo zvayo, uye ndeapi mapfundo anoda kutariswa pakushandiswa? Pano, Meibang achakutsanangurira zvakadzama.
Ingi yemvura yakashandiswa mukudhinda mapepa ane marata kwenguva yakareba kunze kwenyika uye kwemakore anopfuura 20 kumba. Mapepa ane Corrugated printing akagadzirwa kubva paprinda yelead (relief printing), offset printing (offset printing) uye rabha ndiro mvura inogezeswa kudhinda kusvika kumazuva ano anochinjika kudhinda ingi yemvura. Flexible reruve water-based inki yakagadzirawo kubva ku rosin-maleic acid modified resin series (yakaderera giredhi) kusvika ku acrylic resin series (yepamusoro giredhi). Puroti yekudhinda iri kufambawo kubva mundiro yerabha kuenda kune resin ndiro. Muchina wokudhinda wakagadziridzwawo zvishoma nezvishoma kubva pamichina yeruvara rumwe kana maviri ine ma roller mahombe kusvika kumichina yeFLEXO yemavara matatu kana mana.
Kuumbwa uye maitiro emvura-based inki akafanana neaya einki yekudhinda. Ingi-yakavakirwa mvura inowanzo umbwa nemavara, mabhainda, anobatsira uye zvimwe zvikamu. Colorants ndiwo mavara einki-based inki, iyo inopa ingi ruvara rwakasiyana. Kuti uite kuti chiratidziro chive chakajeka mu flexographic printing, mavara-mavara anowanzo shandisa pigments nekugadzikana kwakanaka kwemakemikari uye simba guru remavara; Iyo binder ine mvura, resin, amine makomisheni uye zvimwe organic zvinonyungudutsa. Resin ndiyo inonyanya kukosha muinki-based inki. Mvura-soluble acrylic resin inowanzoshandiswa. Iyo binder chikamu inokanganisa zvakananga basa rekunamatira, kukurumidza kuomesa, anti-sticking performance, nezvimwe zveinki, uye zvinokanganisa gloss uye inki kutapurirana kweinki. Amine makomisheni anonyanya kuchengetedza alkaline PH kukosha kweinki-yakavakirwa mvura, kuitira kuti iyo acrylic resin inogona kupa zvirinani kudhinda maitiro. Mvura kana zvimwe organic zvinonyungudutsa zvinonyanya kunyungudutswa resins, Rongedza viscosity uye kuoma kumhanya kweinki; Vabatsiri vamiririri vanonyanya kusanganisira: defoamer, blocker, stabilizer, diluent, nezvimwe.
Sezvo mvura-based inki iri sipo yakagadzirwa, zviri nyore kugadzira mabhubhu mukushandiswa, saka mafuta e-silicone anofanirwa kuwedzerwa se defoamer kuti inhibit uye kubvisa mabhubhu, uye kuvandudza mashandiro ekufambisa kweinki. Mablocker anoshandiswa kuvharidzira kumhanya kwekuoma kweinki-yakavakirwa mvura, kudzivirira iyo inki kubva pakuoma pane anilox roll uye kuderedza paste. Iyo stabilizer inogona kugadzirisa iyo PH kukosha kweinki, uye inogona zvakare kushandiswa seyakasvibiswa kuderedza viscosity yeinki. Iyo diluent inoshandiswa kuderedza ruvara rwemvura-based inki, uye zvakare inogona kushandiswa seyakajeka kuvandudza kupenya kwemvura-based inki. Mukuwedzera, imwe wakisi inofanira kuwedzerwa kune inki-based inki kuti iwedzere kusakara kwayo.
Mvura-based inki inogona kusanganiswa nemvura isati yaoma. Kana ingi yaoma, haichazonyungudika mumvura neingi. Naizvozvo, mvura-yakavakirwa ingi inofanira kunyandurwa zvizere pamberi kushandiswa kuchengeta ingi kuumbwa yunifomu. Paunenge uchiwedzera ingi, kana iyo inki yakasara mutangi ine tsvina, inofanira kusefa kutanga, yozoshandiswa neingi itsva. Paunenge uchidhinda, usarega inki ichioma pane anilox roll kudzivirira kuvhara gomba reinki. Kuvhara kuwanda kwekutapurirana kweinki kunokonzera kusagadzikana kwekudhinda. Munguva yekudhinda, iyo flexplate inofanira kugara yakanyoroveswa neingi kuti isavhare vhezheni patani yekudhinda mushure mekunge ingi yaoma. Mukuwedzera, inowanikwa kuti kana viscosity yemvura-based inki yakakwirira zvishoma, hazvina kukodzera kuwedzera mvura zvakasununguka kuti irege kukanganisa kugadzikana kweinki. Iwe unogona kuwedzera huwandu hwakakodzera hwekudzikamisa kuti uigadzirise.
