Zvakanakira uye zvakaipira mvura-based inki

Ingi-yakavakirwa mumvura, inoshanda sechigadziriso chekudhindisa, inomira pachena nekuda kwesimba rayo mukusasanganisa zvinonyungudutsa zvinonyungudutsa, zvichideredza zvakanyanya kuburitswa kwemafuta anonyungudika (VOCs), uye nekudaro hazvikuvadze vanogadzira ingi kana hutano hwevashandi, panguva imwe chete. kuwedzera kunaka kwezvakatipoteredza. Yakanyorwa se eco-inoshamwaridzika inki, mabhenefiti ayo ezvakatipoteredza anonyanya kuve mukusakuvadza kune nharaunda, isina chepfu kuvanhu, isingabatike, uye yakachengeteka zvakanyanya, zvinonyatso kudzikisa huturu hwasara pazvinhu zvakadhindwa, kukwenenzvera nzira dzekuchenesa dzemichina yekudhinda, uye kuderedza. njodzi dzemoto dzakabatana nemagetsi akamira uye zvinonyungudutsa zvinobvira, zvinoumba chaiyo "girinhi" yekurongedza zvinhu zvekudhinda.

Panyaya yemhando yekudhinda, ingi yemvura inotaridza kugadzikana kwakasarudzika, kusaora kumapureti ekudhinda, nyore kushanda, kukwanisa kutenga, kusungirirwa kwakasimba kwemashure ekudhinda, kusimba kwemvura, uye kukurumidza kuomesa (kusvika 200 metres paminiti). ), inoshanda mu gravure, flexographic, uye kudhinda skrini ine mukana wakafara. Zvisinei nekunonoka kunyungudika kwehunyoro kuchida masisitimu ekuomesa nekupisa uye kungave kukonzeresa kunyorova zvakare, nyaya idzi dzakagadziriswa nenzira kwayo kuburikidza nekufambira mberi kwetekinoroji.

Kuumbwa kweinki-yakavakirwa mvura kunosanganisira emulsion yepolymer, pigments, surfactants, mvura, uye zvimwe zvinowedzera. Pakati peizvi, emulsions yemvura yepolymer, yakadai se acrylic uye ethylbenzene derivatives, inoshanda sevatakuri ve pigment, kupa kunamatira, kuoma, kupenya, kuomeswa kwehuwandu, kumira kweabrasion, uye kudzivirira kwemvura kune inki, yakakodzera kune zvose zvisingasviki uye zvinotora substrates. Nguruve dzinobva kune dzakasimukira dzakaita sephthalocyanine yebhuruu uye lithol tsvuku kune inorganic yakaita senge kabhoni dema uye titanium dioxide. Masurfactants anobatsira mukuderedza kushushikana kwepasi, kufambisa kunyange inki kugovera pane substrate, uye kuwedzera kugadzikana.

Zvakadaro, zvipingamupinyi zveinki-yakavakirwa mumvura zvinonyanya kutenderera pakunamira kwakadzika, kupenya kushoma, uye kunonoka kuomesa nguva. Nekudaro, nehunyanzvi hwekuvandudza tekinoroji senge yakakwidziridzwa substrate pretreatment, yakagadziridzwa pigment maumbirwo, uye hunyanzvi hwekudhinda, izvi zvinonetsa zvadzikira zvakanyanya, zvichiita kuti inki yemvura iwedzere kukwikwidza uye, kazhinji, kudarika ingi yechinyakare-based inki mumashandisirwo anoshanda. Kunyangwe ingi yemvura ichiunza mutengo wakakwira zvishoma, zvichipihwa hushamwari hwezvakatipoteredza uye kuchengetedza hutano kune vashandisi, mari yekuwedzera inoonekwa sekudyara kwakakodzera.
