Hupenyu hwedu hwakazara nezvinhu zvakasiyana-siyana zvakadhindwa, mbatya, magazini, uye mapurasitiki emarudzi ese. Sevatengesi vemachira ezvekudya nevatengi, tinonyanya kunetseka nezvekuti inki yerudzii isingakuvadzi nharaunda uye yakakodzera indasitiri yemachira ezvekudya. Muchinyorwa chino, tichakuzivisai nezve inki isingakuvadzi nharaunda yakakodzera kudhinda machira ezvekudya: inki inobva mumvura.
Tafura yeZviri Mukati
Pfungwa yeInki Yakavakirwa Pamvura
Nzira yesainzi inoshandiswa kugadzira iyi inonzi inki inobva mumvura, iyo inonyanya kushandisa mvura sechinhu chinonyungudutsa. Inki inobva mumvura nedzimwe inki dzinodhinda hadzina mhedzisiro yakaipa pahutano hwemuchina wekudhinda kana tichienzanisa nezvinonyungudutsa zvavo zvisingachinji uye zvine chepfu. Chinyorwa ichi chine hushamwariwo nezvakatipoteredza. Inki iyi haina hunhu husingabatike chete, asi inobvisawo njodzi yekubatidzwa uye kuputika munzvimbo yekudhinda, izvo zvinobatsira pakushanda kwakachengeteka. Ehe, inki neinki ikozvino zvine mashandisirwo akasiyana-siyana: inki yekudhinda yeoffset, inki yekudhinda yeflexographic, uye inki yekudhinda yegravure. MuEurope, America, Japan, nedzimwe nyika dzakabudirira, inki yave ichitsiva inki, pamwe nekudhinda kweoffset kunze kwedzimwe nzira dzekudhinda dzeinki dzakasiyana. MuUnited States, semuenzaniso, 95% yeprints dzeflexographic uye 80% yeprints dzegravure dzine inki.
Pamusoro pekuchengetedzwa kwezvakatipoteredza, inoshandiswa zvakanyanya munyika yeinki yemvura nekuda kwekushanda kwayo kwepamusoro: kugadzikana kweruvara rweinki, kupenya kwakanyanya, simba rakasimba rekupenda, ndiro isingakanganisi, kunamira kwakasimba mushure mekudhinda, kukurumidza kuchinjika kwekuomesa, kuramba mvura, kudhindwa kwemavara mana, kudhinda kwemavara matema, nezvimwewo. Kugadzirwa nekushandiswa kweinki yemvura muChina kwakatanga kunonoka, asi kufambira mberi kwave kuri nekukurumidza, kunyanya mumakore achangopfuura, izvo zvawedzera kukurumidza kwekukura. Hunhu hweinki yemumba hwakawedzera pamwe chete nekuwedzera kwekudiwa kweinki. Inki, mupfungwa yechinyakare yekuomesa zvishoma nezvishoma, kupenya kusina kunaka, kushaya kuramba mvura, kudhinda kwenhema, nezvimwe zvikanganiso, yakagadziridzwa zvikuru. Mitengo yeinki inopinzwa munyika inowanzo kuve yakakwira, asi inki yeChina yave kutora musika nemagadzirirwo ayo akanaka uye anokwanisika. Mitengo yeinki inopinzwa munyika inowanzo kuve yakakwira, asi inki yeChina yave kutora musika nemagadzirirwo ayo akanaka uye anokwanisika.
Funga nezveHunhu uye Kuumbwa kweInki Yakagadzirwa Nemvura.
Inki inobva mumvura inoumbwa neresini inonyungudika mumvura, pigments dzakaomarara, solvents, uye zvimwe zvinowedzerwa zvakakuyiwa nekugadzirwa kwesainzi. Resini inonyungudika mumvura muinki inonyanya kushanda sechinhu chinobatanidza, ichiparadzira zvidimbu zvepigment zvakaenzana kuitira kuti inki ive nekufamba kwakati uye inonamatira kune substrate kuitira kuti inki igadzire firimu rakafanana mushure mekudhinda. Ruvara rweinki runonyanya kutsanangurwa nepigment, iyo inopararira zvakaenzana muzvinhu zvinobatanidza sezvidimbu, uye zvidimbu zvepigment zvinogona kupinza, kuratidza, kudzoreredza, uye kutumira chiedza, zvichivabvumira kuratidza ruvara rwakati. Kazhinji, pigment inofanira kuva neruvara rwakajeka, ruvara rwakakwana uye simba rekufukidza, uye kupararira kwakanyanya. Uyezve, zvichienderana nekushandiswa, inogona kuva nekudzivirira kwakasiyana-siyana kwekukwesha. Basa resolvent nderekunyungudutsa resin kuitira kuti inki ive nekuyerera, kutamiswa kunogona kuitika zvakanaka mukati mekudhinda, uye viscosity uye kushanda kwekuomesa kweinki kunogona kuchinjwa. Solvent muinki inobva mumvura inonyanya mvura ine ethanol shoma.
Inki Inobva Mumvura Inowanzo shandiswa Zvimwe Zvinowedzera Zvakadai seDefoamer, PH Value Stabilizer, Slow Drying Agent, nezvimwewo.
(1) mushonga wekubvisa gandaBasa remuchina wekubvisa mapombi nderekudzivisa nekubvisa kugadzirwa kwemapumburu emhepo. Kazhinji, kana viscosity yeinki inobva mumvura yakanyanya kukwira, PH yakanyanya kuderera, kana kumhanya kwemuchina wekudhinda kuri nekukurumidza, zviri nyore kugadzira mapumburu. Kana huwandu hwemapumburu anogadzirwa hwakakura, pachava nekubuda kweruvara rweinki chena, isina kuenzana, izvo zvichakanganisa kunaka kwechinhu chakadhindwa.
(2) chinhu chinoomesa zvishoma nezvishoma.Chinhu chinoomesa zvishoma nezvishoma chinogona kumisa nekudzora kumhanya kwekuomesa kweinki inobva mumvura kudzivirira inki iri muplate yekudhinda kana ma anilox rollers kuti isaome uye kuderedza kuwanda kwezvikanganiso zvekudhinda zvinovhara nekunama. Dzora huwandu hwechinhu chinoomesa zvishoma nezvishoma; kazhinji, huwandu hweinki hunofanira kunge huri pakati pe1% ne2%. Kana ukawedzera yakawandisa, inki haizoome zvakakwana, uye print ichave inonamira, yakasviba, kana kuburitsa hwema hwakaipa.
(3) Chinosimbisa kukosha kwePH:Chinosimbisa kukosha kwePH chinoshandiswa zvakanyanya kudzora nekudzora kukosha kwePH kweinki inobva mumvura kuitira kuti igare yakagadzikana pakati pe8.0–9.5. Panguva imwe chete, chinogonawo kudzora viscosity yeinki inobva mumvura nekunyungudutswa kweinki. Kazhinji, huwandu hwakakodzera hwePH hunofanira kuwedzerwa nguva imwe neimwe mukudhinda kuti inki inobva mumvura irambe iri mumamiriro akanaka ekudhinda.
Inki inobva mumvura inochengetedza nharaunda zvakanaka
Inki yakagadzirwa nemvura inosangana nezvinodiwa zvekuchengetedza nharaunda, chigadzirwa ichi hachina chepfu, hachiparadzi, hachitsvedzi, hachiputi, hachiputi, chakachengeteka zvakanaka, chiri nyore kutakura, chine huwandu hwakawanda, dosi shoma, viscosity yakaderera, chinochinjika zvakanaka pakudhinda, kushanda kwakasimba, kusimba kwakanaka pakunamatira, kuoma nekukurumidza, kushanda kwemvura, alkali, uye kukwesha kwakanaka; Kudhinda mapatani akaomarara kunogonawo kuwana mazinga akapfuma, mavara akajeka uye akajeka, nezvimwe zvinhu. Kubatsira kukuru kwekushandisa inki yakagadzirwa nemvura ndekwekuti inoderedza huwandu hwezvinhu zvinopisa (voc) zvinoburitswa mumhepo, izvo zvinobatsira kuvandudza mamiriro ekudhinda, kudzivirira kusvibiswa kwemhepo, uye kuderedza zvakanyanya njodzi yemoto. Kuti ivandudze mhando yenzvimbo, inogona kubvisa zvachose zvimwe zvinhu zvinokuvadza zvine inki yakagadzirwa nemvura kuhutano hwevanhu, pamwe nekusvibiswa kunouya nekurongedza. Inoshanda zvakanaka kwazvo pakudhinda nekurongedza zvinhu zvinoda kucheneswa, zvakaita sechikafu nemishonga.
Semutengesi wemakapu emapepa akawanda, GFP yagara yakazvipira kushandisa zvinhu zvisingakuvadzi nharaunda muzvinhu zvayo, ichitora mutoro wekuchengetedza nharaunda nehutano hwevatengi vayo. Makapu edu emapepa anodhindwa achishandisa inki dzinobva mumvura, uye maitiro ekudhinda anoitwa makapu asati aiswa laminated, saka kana ashandiswa, inki inobva kunze haizokweshe pamadziro emukati mekapu, zvichichengetedza hutano hwevashandisi. Ndapota shanyirai link inotevera kuti muwane rumwe ruzivo nezvemakapu edu emapepa asingakuvadzi nharaunda uye mashandisirwo akafanana.
