Uburyo bwo gucapa nibikoresho byo gucapa

Uburyo bwo gucapa

Mubuhanga, hariho uburyo bwinshi bwo gucapa, nko gucapa mu buryo butaziguye, gusohora gusohora no kurwanya icapiro.

Mu icapiro ritaziguye, icapiro rya paste rigomba kubanza gutegurwa.Ibishishwa, nka alginate paste cyangwa paste ya krahisi, bigomba kuvangwa mukigereranyo gisabwa hamwe n amarangi hamwe nindi miti ikenewe nka mitiweli hamwe nogukosora.Ibi noneho bicapishwa kumyenda yera ukurikije ibishushanyo bifuza.Ku myenda ya sintetike, paste yo gucapa yashoboraga gukorwa hamwe na pigment aho kuba amarangi, hanyuma paste yo gucapa izaba igizwe na pigment, ibifatika, paste ya emulsiya nindi miti ikenewe.

Mugucapura gusohora, igitambaro cyubutaka kigomba kubanza gusiga irangi ryamabara yubutaka bwifuzwa, hanyuma ibara ryubutaka rikarekurwa cyangwa ryahumishijwe ahantu hatandukanye ukabisohora hamwe na paste yasohotse kugirango usige ibishushanyo byifuzwa.Gusohora ibintu bisanzwe bikorwa no kugabanya ibintu nka sodium sulphoxylate-formaldehyde.

Kurwanya icapiro.ibintu birwanya irangi bigomba kubanza gushyirwa kumyenda yubutaka, hanyuma umwenda ugasiga irangi.Umwenda umaze gusiga irangi, rezo izakurwaho, kandi ibishushanyo bigaragara mubice byacapishijwe.

Hariho ubundi bwoko bwo gucapa, kurugero, gucapa sublistatike no gucapa umukumbi.Mu mfuruka, igishushanyo kibanza gucapishwa ku mpapuro hanyuma impapuro zifite ibishushanyo bikanda ku mwenda cyangwa imyenda nka T-shati.Iyo ubushyuhe bukoreshejwe, ibishushanyo byimurirwa kumyenda cyangwa imyenda.Mugihe cyanyuma, shourt fibrous ibikoresho byacapishijwe mubishushanyo kumyenda hifashishijwe ibifatika.Ibikoresho bya elegitoroniki bikoreshwa cyane.

Ibikoresho byo gucapa

Gucapa birashobora gukorwa nogucapisha uruziga, gucapa ecran cyangwa, vuba aha, ibikoresho byo gucapa inkjet.

1. Icapiro

Imashini icapura imashini isanzwe igizwe na silindari nini yo hagati (cyangwa yitwa igikono cyumuvuduko) itwikiriwe na reberi cyangwa isahani myinshi yimyenda yubudodo buvanze itanga silinderi hamwe nubuso bworoshye kandi bworoshye.Ibizingo byinshi byumuringa byanditseho ibishushanyo bigomba gucapwa bishyirwa hafi ya silinderi yumuvuduko, uruziga rumwe kuri buri bara, ruhuye na silinderi.Mugihe bazunguruka, buri cyapa cyanditseho imashini, cyayobowe neza, nacyo gitwara icyuma cyacyo, hanyuma icya nyuma kigatwara paste yo gucapa kuva mumasanduku yamabara yacyo kugeza kumpapuro zanditseho.Icyuma gityaye cyiswe umuganga wogusukura gikuraho paste irenze kurupapuro rwandika, ikindi cyuma cyitwa umuganga wintoki cyakuweho ikintu cyose cyangwa umwanda wafashwe nicyuma cyandika.Umwenda ugomba gucapurwa ugaburirwa hagati yimashini zicapura na silinderi yumuvuduko, hamwe nigitambara cyinyuma cyumukara kugirango wirinde hejuru ya silinderi kwanduzwa niba paste yamabara yinjiye mumyenda.

Icapiro rya Roller rirashobora gutanga umusaruro mwinshi cyane ariko gutegura ibipapuro byanditseho ibicapo bihenze, mubyukuri, bituma bihuza gusa nigihe kirekire cyo gukora.Byongeye kandi, diameter ya printer yo gucapa igabanya ingano yubunini.

2. Icapiro rya ecran

Icapiro rya ecran, kurundi ruhande, rikwiranye na ordre ntoya, kandi irakwiriye cyane cyane gucapa imyenda irambuye.Mugucapisha ecran, imashini zikozwe mesh zigomba kubanza gutegurwa ukurikije ibishushanyo bigomba gucapwa, imwe kuri buri bara.Kuri ecran, ahantu hatagira paste yamabara igomba kwinjiramo hasizwe na firime idashobora gusigara hasigara interineti isigaye ifunguye kugirango yemere paste gucamo.Gucapura bikorwa muguhatira icapiro ryabigenewe binyuze mumashusho mesh kumyenda munsi.Mugaragaza yateguwe mugusiga ecran hamwe na fotogelatine mbere hanyuma ukarenga ishusho itari nziza yubushushanyo hanyuma ukayishyira kumurabyo ikosora kandi idashobora gukata firime kuri ecran.Ipitingi yogejwe muri utwo duce tutarakize, hasigara interstice muri ecran.Gucapisha gakondo gakondo ni ecran ya ecran, ariko icapiro rya ecran naryo rirakunzwe cyane kubikorwa byinshi.

3. Icapiro rya Inkjet

Birashobora kugaragara ko kubicapiro bya roller cyangwa ecran-icapiro imyiteguro ni igihe n'amafaranga atwara nubwo sisitemu ya mudasobwa ifashijwe (CAD) yakoreshejwe cyane muruganda rwinshi rwo gucapa kugirango ifashe mugutegura igishushanyo.Ibishushanyo bigomba gucapwa bigomba gusesengurwa kugirango hamenyekane amabara ashobora kubigiramo uruhare, hanyuma ibishushanyo bibi bitegurwe kuri buri bara hanyuma byimurwe mubicapiro cyangwa ecran.Mugihe cyo gucapa ecran mubikorwa byinshi, bizunguruka cyangwa biringaniye, ecran igomba guhinduka kandi igasukurwa kenshi, nabyo bikaba bitwara igihe kandi bitwara akazi.

Kugirango duhuze ibyifuzo byumunsi kubisubizo byihuse hamwe nubunini buto bwa tekinoroji ya inkjet ikoreshwa cyane.

Icapiro rya Inkjet kumyenda ikoresha tekinoroji isa niyakoreshejwe mugucapa impapuro.Ibisobanuro bya digitale yubushakashatsi bwakozwe hakoreshejwe sisitemu ya CAD birashobora koherezwa kuri printer ya inkjet (cyangwa bikunze kwitwa printer ya inkjet ya digitale, kandi imyenda yacapishijwe nayo ishobora kwitwa imyenda ya digitale) hanyuma igacapishwa kumyenda.Ugereranije nubuhanga gakondo bwo gucapa, inzira iroroshye kandi umwanya muto nubuhanga birakenewe nkuko inzira yikora.Byongeye kandi, umwanda muke uzaterwa.

Muri rusange, hari amahame abiri yibanze yo gucapa inkjet kumyenda.Imwe ni Gukomeza Ink Jetting (CIJ) indi yitwa "Tera kubisabwa" (DOD).Mubihe byashize, umuvuduko mwinshi cyane (hafi 300 kPa) wubatswe binyuze muri pompe itanga wino uhatira wino guhora kuri nozzle, diameter ikaba isanzwe igera kuri micrometero 10 kugeza 100.Munsi yinyeganyeza yumurongo mwinshi uterwa na vibrateri ya peizoelectric, wino noneho igacika mumigezi yigitonyanga hanyuma igasohoka muri nozzle kumuvuduko mwinshi.Ukurikije ibishushanyo mbonera, mudasobwa izohereza ibimenyetso kuri electrode yishyuza yishyuza amashanyarazi ibitonyanga byatoranijwe.Iyo unyuze muri electrode ya deflection, ibitonyanga bitarishye bizahita bijya mu muyoboro wo gukusanya mu gihe ibitonyanga bya wino byashizwemo byerekeza ku mwenda kugira ngo bibe igice cyacapwe.

Muri tekinike ya "guta kubisabwa", ibitonyanga bya wino bitangwa nkuko bikenewe.Ibi birashobora gukorwa hakoreshejwe uburyo bwo kohereza amashanyarazi.Ukurikije ibishushanyo bigomba gucapurwa, mudasobwa yohereza ibimenyetso byifashishijwe mu gikoresho cya piezoelectric nacyo kigahinduka kandi kigatanga igitutu ku cyumba cya wino binyuze mu bikoresho byoroshye.Umuvuduko utera inkuta za wino zisohoka muri nozzle.Ubundi buryo busanzwe bukoreshwa muri tekinike ya DOD ni uburyo bwo gukoresha amashanyarazi.Mu gusubiza ibimenyetso bya mudasobwa umushyushya utanga ibibyimba mu cyumba cya wino, kandi imbaraga zagutse zibyibushye zirekura ibitonyanga byino.

Tekinike ya DOD ihendutse ariko umuvuduko wo gucapa nawo uri munsi yubwa tekinike ya CIJ.Kubera ko ibitonyanga bya wino bisohoka ubudahwema, ibibazo byo gufunga nozzle ntibizabaho muburyo bwa CIJ.

Mucapyi ya Inkjet mubisanzwe ikoresha guhuza amabara ane, ni ukuvuga cyan, magenta, umuhondo numukara (CMYK), kugirango icapishe ibishushanyo bifite amabara atandukanye, bityo imitwe ine yo gucapa igomba guteranyirizwa hamwe, imwe kuri buri bara.Nyamara printer zimwe zifite imitwe 2 * 8 yo gucapa kuburyo mubyukuri amabara agera kuri 16 ya wino ashobora gucapwa.Icapa ryicapiro rya printer ya inkjet irashobora kugera kuri 720 * 720 dpi.Imyenda ishobora gucapishwa hamwe nicapiro rya inkjet itandukana kuva fibre karemano, nka pamba, silike nubwoya, kugeza kuri fibre synthique, nka polyester na polyamide, kubwibyo hariho ubwoko bwinshi bwa wino igomba guhaza ibyifuzo.Harimo wino idakira, wino ya aside, ikwirakwiza wino ndetse na wino ya pigment.

Usibye gucapa imyenda, printer ya inkjet irashobora no gukoreshwa mugucapura T-shirt, amashati, amashati ya polo, kwambara kwabana, udufuka nigitambaro.
