Chinhu chikuru cheingi-yakavakirwa mumvura ndiyo inonyungudika inotakura yavanoshandisa. Mutakuri wekunyunguduka weinki inonyungudika ndeye organic solvents, senge toluene, ethyl acetate, ethanol, etc. Iyo yakanyungudika inotakura yeinki ine mvura imvura, kana yakasanganiswa nedoro shoma (inenge 3% ~ 5%). Nekuda kwekushandiswa kwemvura semutakuri wekunyunguduka, inki yakavakirwa pamvura ine zvakakosha kudzivirira kwezvakatipoteredza uye hunhu hwekuchengetedza, yakachengeteka, isina chepfu, isingakuvadzi, isingabatike uye isingaputike, inenge isina inoputika organic gasi kugadzirwa, kunyanya muzvikamu zvina zvinotevera:
1. Hapana kusvibiswa kune nharaunda yemhepo. Nekuda kwekuti ingi dzemvura dzinoshandiswa sekunyungudutsa vatakuri nemvura, havangambobudisi organic gasi (VOCs) kumhepo panguva yekugadzirwa kwavo kana pavanenge vachishandiswa kudhinda, uye maVOC anoonekwa seimwe yenzvimbo huru dzekusvibisa mumhepo yepasirese nhasi. Izvi hazvifananidzi ne solvent-basedinks.
2. Deredza chepfu yakasara pamusoro pechinhu chakadhindwa kuti uve nechokwadi chehutsanana hwekudya uye kuchengeteka. Ingi-yakavakirwa mvura inogadzirisa zvachose dambudziko rehupfu hwemainki ane solvent. Sezvo isina organic zvinonyungudutsa, izvo zvakasara zvine chepfu pamusoro pezvakadhindwa zvakaderedzwa zvakanyanya. Hunhu uhu hunoratidza hutano hwakanaka nekuchengetedzeka mukurongedza nekudhinda zvigadzirwa zvine hutsanana hwakanyanya sefodya, doro, chikafu, zvinwiwa, mishonga, uye matoyi evana.
3. Kuderedza kushandiswa kwezviwanikwa uye kuderedza mari yekuchengetedza zvakatipoteredza. Nekuda kwehunhu hwemainki emvura, ayo akakwira muhomomorphs, anogona kuiswa pamafirimu einki akaonda. Nokudaro, kana zvichienzaniswa ne-solvent-based inki, ine chiyero chiduku chekuputira (huwandu hweinki inopedzwa pane imwe nzvimbo yekudhinda). Mushure mekuedza, huwandu hwekuputira hwakaderedzwa neanenge 10% kana ichienzaniswa neinki-based inki. Mune mamwe mazwi, kushandiswa kweinki dzemvura kunoderedzwa neanenge 10% kana zvichienzaniswa neinki-based inki yekudhinda nhamba imwechete uye kutsanangurwa kwezvakadhindwa.
4. Kuvandudza kuchengetedzwa kwenzvimbo yekushanda uye kuve nechokwadi chehutano hwevashandi vekuonana. Ingi dzakanyungudika dzine njodzi mukugadzira kwadzo uye kana dzichidhindwa. Organic solvents uye solvent-based inki pachazvo zvinwiwa zvinopfuta, organic solvents zviri nyore kushanduka, uye inoputika gasi musanganiswa uchaumbwa mumhepo, uye kuputika kuchaitika kana vasangana nepfarivari mushure mekusvika painoputika. Nekuda kweizvozvo, njodzi yemoto uye kuputika munzvimbo yekugadzira yakanyanya. Kushandiswa kweinki dzemvura kunodzivirira njodzi dzakadaro zvakanyanya.
