Gukurura wino bivuga inzira yo kumurika, aho kole ikurura hasi ya wino hejuru yicapiro ryicapiro rya substrate, bigatuma wino ifata kumurongo wo hejuru wa reberi cyangwa meshi. Igisubizo ni inyandiko cyangwa ibara rituzuye, bivamo ibicuruzwa bivanyweho. Byongeye kandi, wino ifatanye na kole yo hejuru yimuriwe kumurongo ukurikira, itera imyanda. Igice kitagira ibara gifite ibibara bya wino no kugabanuka gukabije mu mucyo, bigira ingaruka ku bwiza bwibicuruzwa.
1.Bifitanye isano nubunini bwa kole ikoreshwa hamwe nibikorwa bya concentration
Amahirwe yikintu kimwe gishyushye gishonga gifata gukurura wino irarenze iyibice bibiri bifata,ikaba idatandukanijwe nubwoko nyamukuru bufatika kandi bworoshye.
Bitewe nubunini buke bwa kole bwakoreshejwe, ingano ya wino ikururwa hasi ni muburyo bwurudodo rwiza, nkibimenyetso biterwa na meteor. Utudomo twiza tugaragara cyane mugace ka firime ya plastike, kandi mugice cyashushanyije, birakenewe ko ubyitondera kugirango ubivumbure. Ingano yo gufunga ubwoko bwa scraper imashini yumye ya laminating igenwa numubare wimirongo hamwe nubujyakuzimu bwa anilox. Umuvuduko ukabije kuri scraper mugihe gikora nyirizina uzagabanya kandi ingano ya kole ikoreshwa. Niba ingano ya kole ikoreshwa ari nto, ibintu byo gukurura wino birakomeye, mugihe niba ingano ya kole ikoreshwa ari nini, ibintu byo gukurura wino biragabanuka.
Kwibanda kumikoro yo mu rugo bifitanye isano rya bugufi no gukurura wino.Niba intumbero yikintu kimwe gifatika kiri munsi ya 35%, ibikomeye byibanze byingenzi ntibiri munsi ya 3g /㎡, cyangwa kwibumbira hamwe ibice bibiri bifatika bifata neza ntibiri munsi ya 20%, kandi ibikomeye byingenzi bifata munsi ya 3.2g /㎡, biroroshye kugaragara inkingi yo gushushanya, nayo ijyanye nibikorwa nyirizina. Niba ibikorwa byo kwibandaho ari bike kandi gukurura wino bibaye, birakenewe kongera imbaraga yibikorwa kugirango bikemuke, bivuze mubyukuri kongera umubare wibikorwa nyamukuru cyangwa kugabanya ingano ya diluent yakoreshejwe.Mubisanzwe, kwibanda kumurimo wikintu kimwe bigenzurwa hafi 40%, kandi nibyiza kugenzura ubunini bwibice bibiri kuri 25-30%, kugirango ibintu bikurura wino bikemuke.
2. Bifitanye isano numuvuduko wa kole
Mubikorwa byumye byumye, uruzitiro rwumuvuduko rusanzwe rukoreshwa, rumenyereyekora ibifuniko bifatika kandi bigabanye ibisekuruza. Iyo gukurura wino bibaye, usibye gusuzuma ingano ya kole yakoreshejwe hamwe nubunini bwibikorwa, ni umuvuduko wa rubber.
Mubisanzwe, iyo umuvuduko urenze 4MPa, haribishoboka gukurura wino. Igisubizo nukugabanya umuvuduko, kandi mugihe kimwe, umukoresha kabuhariwe agomba gukoresha umwenda kugirango ashyiremo umwirondoro kugirango ahanagure agace ka wino ya roller ya anilox ikora. Niba bikabije, roller ya anilox igomba guhagarikwa kugirango isukure.
3. Bifitanye isano nubwiza bwa kole
Rubber rollerntabwo byoroshye cyangwa byoroshye, kandi irashobora gukurura wino, igaragara cyane kumurongo umwe ushyushye ushonga.
Bitewe n'ubusumbane n'ubukonje bwa resin, wino yakuweho ntisanzwe kandi igabanijwe ku buryo butaringaniye, hasigara ibibara bya wino ahantu hatagaragara, bigatuma kugabanuka gukorera mu mucyo, gutakaza wino mu ibara, hamwe ninyandiko ituzuye. Guhindura iki kintu, birakenewe gusimbuza uruziga rworoshye kandi rworoshye.
4. Bifitanye isano n'umuvuduko wimashini n'ubushyuhe bwumye
Umuvuduko wimashini werekana ko intera iri hagati yino ya wino hamwe na afashe kumurongo wa firime ihinduka mugihe cyo gutose.
Akenshi, kubera umuvuduko wimashini itinda, habaho ibintu byo gukurura wino, bikemurwa no kongera umuvuduko no kugabanya igihe cyo gutura hagati yino ya wino hamwe ninteruro ifatika. Mubyigisho, niba umuvuduko wimashini wiyongereye, ubushyuhe bwumye nabwo bugomba kwiyongera. Muri icyo gihe, niba umuvuduko wimashini wiyongereye mugihe gikora, hagomba kurebwa niba hari andi makosa, nko kwimura ibintu, kandi bigomba guhinduka.
5. Bifitanye isano no gufatira icapiro substrate cyangwa wino
Niba ubwoko butandukanye bwa wino bukoreshwa mugucapisha gravure, kugaragara kw'amakosa bigaragarira byoroshye mugihe cyo kumurika.
Irangi irashobora kugabanywamo wino yo gucapa hejuru hamwe na wino yo gucapa imbere. Bitewe nubwoko butandukanye bwa wino, gufatira hamwe bishobora kuba bitandukanye cyangwa bidahuye, kandi gufatana intege nke bishobora gutera gukomera. Iyo lamination yumye ikoreshwa, biroroshye gutera wino gukurura. Iyo ubuso bwubuso bwo gucapa substrate ari bubi, birashoboka cyane gukurura wino.
Irangi rya wino yakuweho igaragara muri rusange, kandi wino ifata ku kibase cya kole, itera umwanda n'umwanda. Niba bimaze gucapurwa, kugirango wirinde imyanda, umuvuduko wimashini urashobora kwiyongera, ingano ya kole irashobora kwiyongera, hamwe nubunini bwa kole bishobora kwiyongera icyarimwe. Mugabanye umuvuduko kuri rubber mugihe ugabanya impagarara zidashaka.
6. Bifitanye isano nubukanishi
Mugihe cyo gukora, niba kunanirwa gukanika bibaye, bikavamogufunga kuringaniza cyangwa gutwikira nabi, irashobora kandi gutera inkingi.
Guhuza ibice byo hejuru bya rubber hamwe na anilox roller byujujwe nibikoresho bibiri bihuye. Niba hari inkingi yo gukurura, hagomba gukorwa ubushakashatsi bwitondewe. Bizagaragara ko gukurura wino bibaho bitewe no kunyeganyega hejuru ya reberi yo hejuru hamwe no gutwikira nabi. Impamvu yo kunyeganyezwa biterwa no kwambara cyane hamwe namenyo y'ibikoresho bya asinchronous.
Niba ufite ibyo usabwa byose, urashobora kutwandikira. Nkumushinga wogupakira byoroshye mumyaka irenga 20, tuzatanga ibisubizo byukuri byo gupakira ukurikije ibicuruzwa byawe hamwe na bije.
