Sobanukirwa vuba inzira yo kohereza amazi mu buryo bw'amayobera

Intangiriro: Bitewe no kunoza imikoreshereze y’abaguzi, ibicuruzwa byihariye byakozwe ku giti cyabo birimo kugenda bikundwa cyane n’abaguzi. Ikoranabuhanga ryo kohereza amazi rica mu buryo butaringaniye budashobora gucapwa hakoreshejwe icapiro ritambitse. Nyuma yo gucapa amazi, ibicuruzwa bifite urugero rwo hejuru rwo kwigana, kandi kongeramo ibicuruzwa byabyo byikubye kabiri, kandi icapiro ryihariye ryo kohereza rinahura neza n’ibyo abaguzi bakeneye mu gihe cya none. Iyi nkuru ipakiye naipaki y'umukororombya wa Shanghai, kandi nzabagezaho ibintu byinshi bigira ingaruka ku ihinduka ry'amabara ya silk ecran.

Ikoranabuhanga ryo kohereza amazi ni ubwoko bw'icapiro rikoresha umuvuduko w'amazi kugira ngo rinyure mu buryo bwa hydrolyze impapuro/plastiki zikoresha imiterere y'amabara. Akamaro karyo ka tekiniki ni uko ridakenera ibikoresho byihariye, ntirigengwa n'ibikoresho by'ikoranabuhanga, ridasaba ibikoresho byihariye byo gukoresha, kandi ridasaba ubushyuhe bwinshi, igihe cyose hari igikoresho cyo kwinjiza amashusho (scanner cyangwa digital camera), igikoresho cyo gushushanya (mudasobwa), igikoresho cyo gusohora amashusho (Inkjet printer), hamwe n'iwino yo kohereza amazi, impapuro zo kohereza amazi, ushobora gucapa ishusho iyo ari yo yose ku kintu cyose gikomeye n'ubuso ubwo aribwo bwose bugose.

Kohereza ikimenyetso cy'amazi

Kohereza ibimenyetso by'amazi ni uburyo bwo kohereza burundu amashusho n'inyandiko biri ku rupapuro rwo kohereza ku buso bwa substrate. Bisa cyane n'uburyo bwo kohereza ubushyuhe, uretse ko umuvuduko wo kohereza uterwa n'umuvuduko w'amazi. Ni ikoranabuhanga rizwi cyane ryo kohereza amazi vuba aha. Agace gato k'amakuru y'amashusho gashobora koherezwa ku buso bwa substrate, bisa n'ingaruka zo gucapa kw'uburyo bwo gucapa, ariko ikiguzi cy'ishoramari ni gito, uburyo bwo gukora ni bwo bworoshye, kandi bukundwa cyane n'abakoresha. Uburyo bwo kohereza ibimenyetso by'amazi ntibusaba ko hakorwa na activator, burinda kwanduza ibintu bivangwa n'ibinyabuzima, kandi bufite inyungu zigaragara mu gukora ubukorikori n'imitako.

01 Ishyirwa mu byiciro

Kwimura irangi ry'amazi

Uburyo bwo gusiga irangi ry'amazi ni ugushushanya ubuso bwose bw'ikintu, gupfuka isura y'umwimerere y'ikintu, no kubasha gucapa imiterere ku buso bwose (bw'ibice bitatu) by'ikintu. Iyi ni yo nyungu yacyo; ariko ikibi nacyo kiragaragara, ni ukuvuga ko cyoroshye. Iyo icyuma gifata amashusho gihuye rwose n'icyatsi, ntabwo byanze bikunze kizaranduka kandi kigahinduka. Kubwibyo, mu by'ukuri, biragoye ko igishushanyo cyimurirwa ku buso bw'ikintu kugira ngo kigere ku rwego rwo kwizerwa.

Inyinshi mu mashusho n'inyandiko byacapwe by'impapuro zo kohereza amazi bikoreshwa mu kohereza amazi bigizwe n'amabara y'umutako n'imiterere yoroshye gusubiramo, kandi nta mpamvu yo gukoresha firime nziza yoroshye gufotora mu gucapa; firime zo kohereza amazi ahanini zikozwe mu buryo bworoshye kugorama. Zikozwe muri firime nziza ishobora gushonga mu mazi. Filime yo kohereza ikoreshwa mu kohereza amazi mu buryo butatu iragoye kohereza no gukoporora inyandiko nziza n'amashusho ajyanye n'urwego.

02 Kohereza ibikoresho
Ingufu zo kohereza amazi

Igice cyo kohereza amazi gishobora kuba firime ya pulasitiki cyangwa impapuro zo kohereza amazi. Ibikoresho byinshi biragoye gucapa mu buryo butaziguye. Ushobora gucapa amashusho n'inyandiko kuri icyo gice cyo kohereza amazi ukoresheje ikoranabuhanga ryo gucapa rikuze, hanyuma ugahita wimura amashusho kuri icyo gice. Ibikoresho.

1) Filimi yo gupfuka amazi ifite imiterere itatu

Filimi y'amazi icapishwa ku buso bwa firime ya polyvinyl alcohol ishongeshwa n'amazi hakoreshejwe uburyo bwa gakondo bwo gucapa gravure. Ifite umuvuduko mwinshi wo gutambuka kandi byoroshye gupfuka ubuso bw'ikintu kugira ngo igere ku buryo butatu bwo kwimura. Ingorane ni uko mu gihe cyo gupfuka, bitewe n'uburyo bwinshi bwo koroha bw'inyuguti, amashusho n'inyandiko biroroshye guhindura. Kubera iyo mpamvu, amashusho n'inyandiko muri rusange bikozwe nk'ibishushanyo bihoraho, nubwo iyo wimura yangiritse, ingaruka zo kureba ntizizagira ingaruka. Muri icyo gihe, firime y'amazi yo gupfuka gravure ikoresha wino yo kohereza amazi. Ugereranyije n'inyino gakondo, wino yo kohereza amazi yo kohereza ifite ubushobozi bwo kwirinda amazi, kandi uburyo bwo kumisha ni ugukamisha kwa volatilization.

2) Impapuro zo kohereza ibimenyetso by'amazi

Ibikoresho by'ibanze by'impapuro zo kohereza ibimenyetso by'amazi ni impapuro zihariye. Ibikoresho by'ibanze bigomba kuba bifite ubuziranenge buhamye, ingano nyayo, bihuye neza n'aho byacapwe, bito cyane, ntibigoye kubyimba no guhindura isura, byoroshye gucapa no gusiga irangi, kandi urwego rw'ubuso rufatanye rutwikiriye neza. Ibiranga nko kwihuta cyane mu mazi. Mu miterere, nta tandukaniro rinini riri hagati y'impapuro zo kohereza amazi n'ifiriti yo kohereza amazi, ariko inzira yo gukora iratandukanye cyane. Muri rusange, impapuro zo kohereza ibimenyetso by'amazi zikoreshwa mu gukora ibishushanyo n'inyandiko ku buso bw'ubutaka hakoreshejwe icapiro rya ecran cyangwa icapiro rya offset. Uburyo buzwi cyane mu gukora ni ugukoresha imashini zicapa inkjet kugira ngo ukore impapuro zo kohereza ibimenyetso by'amazi. Biroroshye gukora ibishushanyo n'inyandiko byihariye ukurikije ibyo ukunda. 

Igikorwa

Activator ni organic solvent ivanze ishobora gushonga vuba ikangiza firime ya polyvinyl alcohol, ariko ntizangiza urwego rwa graphic printing. Iyo activator ikoze ku rundi ruhande rwa graphic printing, ishobora kuyikoresha no kuyitandukanya na firime ya polyvinyl alcohol. Ishyirwa ku buso bwa substrate kugira ngo amazi ashobore gukwirakwira.

gusiga

Kubera ko urwego rwacapwe rw'ifiriti ipfundikiye amazi rufite ubukana buke kandi rworoshye gushwara, igikoresho cyo gukora nyuma yo kwimura ipasi igomba gusukwaho irangi ribonerana kugira ngo ikingire, bityo bikarushaho kunoza imiterere y'imitako. Gukoresha varnish ibonerana ya PV cyangwa irangi rya UV rigabanya urumuri rwa UV bishobora gukora ingaruka mbi cyangwa mbi.
