Monga tonse tikudziwa, ukadaulo wamagetsi wa inkjet walamulira pamsika waukulu wosindikiza wa inkjet kwazaka zambiri. M'malo mwake, ukadaulo wa piezoelectric inkjet wayambitsa kusintha kwa ukadaulo wa inkjet. Ikugwiritsidwa ntchito kwa osindikiza pakompyuta kwanthawi yayitali. Ndikukula ndi kukhwima kwa ukadaulo, osindikiza akulu-akulu a piezoelectric inkjet nawonso atuluka m'zaka zaposachedwa.

Monga momwe dzinali likusonyezera, mfundo yaukadaulo wa inkjet wamafuta otentha ndikugwiritsa ntchito kulimbana pang'ono kuti inki itenthe msanga, kenako ndikupanga thovu lotulutsidwa. Mfundo ya piezoelectric inkjet imagwiritsa ntchito piezoelectric crystal kuti ikhudze ndikusunthira chotsekera chokhazikika pamutu wosindikiza kuti inki pamutu wosindikiza ichotsedwe.

Kuchokera pamfundo zomwe zatchulidwazi, titha kufotokozera mwachidule zabwino zaukadaulo waukadaulo wa piezoelectric inkjet mukagwiritsidwa ntchito pamitundu yayikulu yosindikiza: 　　

(1) Zimagwirizana ndi inki zambiri

Kugwiritsa ntchito ma nozoles a piezoelectric kumatha kukhala kosavuta posankha ma inki amitundu yosiyanasiyana. Popeza njira yotenthetsera inkjet imafunika kutenthetsera inki, kapangidwe kake ka inkiyo kamayenera kufanana ndi katiriji wa inki. Popeza njira ya piezoelectric inkjet siyenera kutentha inki, inki imatha kusankha zambiri.

Njira yabwino kwambiri yopindulira ndi kugwiritsa ntchito inki yokhala ndi inki. Ubwino wa inki inki ndikuti imagonjetsedwa ndi UV radiation kuposa inki (utoto), ndipo imatha kukhala panja panja. Zitha kukhala ndi izi chifukwa ma molekyulu a pigment mu inki ya pigment amatha kuphatikiza m'magulu. Tinthu tating'onoting'ono tomwe tapangidwa ndi ma molekyulu a pigment titawunikiridwa ndi cheza cha ultraviolet, ngakhale mamolekyu ena a pigment awonongedwa, pali ma molekyulu ena okwanira kukhalabe ndi Mtundu woyambirira.　

Kuphatikiza apo, mamolekyulu amtundu wa pigment amapangidwanso lattice. Pansi pa radiation ya ultraviolet, latisi ya kristalo imwazika ndikutenga gawo la mphamvu ya ray, potero limateteza tinthu tating'onoting'ono kuti tisawonongeke. Izi ndizofunikira kwambiri.

Inde, inki ya pigment imakhalanso ndi zofooka zake, zowonekera kwambiri ndikuti pigment imakhalapo mu tinthu tambiri mu inki. Tinthu timeneti timamwaza kuwala ndikupangitsa chithunzicho kukhala chamdima. Ngakhale opanga ena adagwiritsa ntchito inki za pigment m'matenthedwe osindikizira a inkjet m'mbuyomu, chifukwa cha kuchuluka kwa ma polymerization ndi mpweya wama molekyulu a pigment, ndizosapeweka kuti mipweya yake idzatsekedwa. Ngakhale itatenthedwa, imangoyambitsa inki. Kuchulukako kumakhala kovuta kumvetsetsa, ndipo kutseka ndikowopsa. Pambuyo pazaka zambiri zakufufuza, palinso inki zamagetsi zosinthira matenthedwe osindikizira a thovu pamsika lero, kuphatikiza makina opangira inki kuti achepetse kuchuluka kwa ma particles, ndipo kupera Kwabwino kumapangitsa kukula kwa mamolekyulu a pigment kukhala ochepa kuposa kutalika kwa kutalika kwa mawonekedwe onse kuti apewe kufalikira kwa kuwala. Komabe, ogwiritsa ntchito adanenanso kuti vuto lokutidwa lidakalipo, kapena utoto wazithunzi ukadali wowala.

Mavuto omwe ali pamwambapa adzachepetsedwa kwambiri muukadaulo wa piezoelectric inkjet, ndipo cholinga chomwe chimapangidwa ndikukula kwa kristalo chitha kuonetsetsa kuti nozzle siyimitsidwa, ndipo ndende ya inki imatha kuyendetsedwa molondola chifukwa sichimakhudzidwa ndi kutentha. Kapena, inki yocheperako imathanso kuchepetsa vuto lakuda.

(awiri) atha kukhala ndi zida zolimba zotsogola zamagetsi zamagetsi zamagetsi amatha kusankha inki yokhala ndi zolimba kwambiri. Nthawi zambiri, inki yamadzi yomwe imagwiritsidwa ntchito pamaprinta otentha a inkjet imayenera kukhala pakati pa 70% ndi 90% kuti mipweya ikhale yotseguka komanso kuti igwirizane ndi kutentha. Ndikofunikira kulola nthawi yokwanira kuti inki iume pazanema popanda kufalikira panja, koma vuto ndilakuti izi zimalepheretsa osindikiza amtundu wa inkjet kuti asakulitse liwiro losindikiza. Chifukwa cha ichi, osindikiza ma piezoelectric inkjet pamsika ali achangu kuposa osindikiza otentha.

Popeza kugwiritsa ntchito ma nozole a piezoelectric amatha kusankha inki yokhala ndi zolimba kwambiri, kukulitsa ndi kupanga media yopanda madzi ndi zina zotheka kuzikhala kosavuta, ndipo atolankhani opangidwa amathanso kukhala opanda magwiridwe antchito. 　　

(2) Chithunzicho chikuwonekera kwambiri

Kugwiritsa ntchito ma nozole a piezoelectric kumatha kuwongolera mawonekedwe ndi kukula kwa madontho a inki, zomwe zimapangitsa chithunzi chowonekera bwino.

Mukamagwiritsa ntchito ukadaulo wa inkjet wamafuta, inkiyo imagwera pamwamba pa sing'anga ngati kuwaza. Inki ya piezoelectric inkjet imaphatikizidwa ndi sing'anga mwa mawonekedwe a Lay. Pogwiritsira ntchito magetsi ku kristalo wa piezoelectric ndikufanizira kukula kwa inkjet, kukula ndi mawonekedwe amadontho a inki amatha kuwongoleredwa bwino. Chifukwa chake, pachiwonetsero chomwecho, chithunzi chojambulidwa ndi chosindikizira cha piezoelectric inkjet chikhala chowoneka bwino komanso chofewa.

(3) Kupititsa patsogolo ndikupanga zabwino

Kugwiritsa ntchito ukadaulo wa inkie wa piezoelectric kumatha kupulumutsa mavuto obwezeretsa mitu ya inki ndi makatiriji a inki ndikuchepetsa ndalama. Muukadaulo wa piezoelectric inkjet, inki sidzakhala yotenthedwa, kuphatikiza ndi cholinga chopangidwa ndi kristalo wa piezoelectric, nozzle ya piezoelectric itha kugwiritsidwa ntchito kwathunthu.

Pakadali pano, kampani ya Yinghe yadzipereka pakupanga osindikiza mwachangu komanso molondola kwambiri a piezoelectric inkjet. Pakadali pano, makina osindikizira a 1.8 / 2.5 / 3.2 opangidwa ndi kampani yathu amalandiridwa ndi makasitomala ambiri akunja komanso akunja. Makina athu a piezoelectric inkjet amatenga zokhazokha Kuyamwa kwa inki ndikuwongolera zokhazokha kumatsimikizira kuti ma nozzles sanayimitsidwe ndipo ma nozzles nthawi zonse amakhala bwino. Njirayi imapereka mitundu 1440 yolondola kwambiri komanso yosanja kwambiri. Ogwiritsa ntchito amatha kusankha zida zosiyanasiyana zosindikizira. Kugwiritsa ntchito kuyanika katatu ndi kuyanika kwa mpweya kumatha kukwaniritsa nthawi yomweyo Utsi ndi ntchito yowuma, mtengo wotsika kwambiri wopanga, ndikulolani kuti mubwerere mwachangu.
