Miyoyo yathu ili ndi zinthu zosiyanasiyana zosindikizidwa, zovala, magazini, ndi ma CD amitundu yonse. Monga ogulitsa ndi ogula ambiri okonza chakudya, timadera nkhawa kwambiri ndi mtundu wa inki yomwe ndi yosamalira chilengedwe komanso yoyenera makampani opanga chakudya. M'nkhaniyi, tikukudziwitsani za inki yosamalira chilengedwe yomwe ndi yoyenera kwambiri kusindikiza ma CD a chakudya: inki yochokera m'madzi.

Lingaliro la Inki Yochokera M'madzi
Njira yasayansi imagwiritsidwa ntchito popanga inki yotchedwa madzi, yomwe nthawi zambiri imagwiritsa ntchito madzi ngati chosungunulira. Inki yochokera m'madzi ndi inki zina zosindikizira sizimavulaza thanzi la wogwiritsa ntchito makina osindikizira poyerekeza ndi zosungunulira zawo zapoizoni komanso zopanda mphamvu. Chosindikizidwacho chilinso choteteza chilengedwe. Inki sikuti ili ndi mphamvu zosayaka zokha, komanso imachotsa chiopsezo chobisika cha kuyaka ndi kuphulika m'malo osindikizira, zomwe zimathandiza kuti ntchito ikhale yotetezeka. Zachidziwikire, inki ndi inki tsopano zili ndi ntchito zosiyanasiyana: inki yosindikizira ya offset, inki yosindikizira ya flexographic, ndi inki yosindikizira ya gravure. Ku Europe, America, Japan, ndi mayiko ena otukuka, inki yakhala ikusintha inki m'malo mwake, komanso kusindikiza kwa offset kunja kwa njira zina zosindikizira za inki yapadera. Mwachitsanzo, ku United States, 95% ya zosindikizira za flexographic ndi 80% ya zosindikizira za gravure zili ndi inki.
Kuwonjezera pa kuteteza chilengedwe, imagwiritsidwa ntchito kwambiri padziko lonse lapansi pa inki yamadzi chifukwa cha ntchito yake yabwino kwambiri: kukhazikika kwa mtundu wa inki, kuwala kwambiri, mphamvu ya utoto wamphamvu, mbale yosawononga, kumamatira mwamphamvu pambuyo posindikiza, liwiro losinthika louma, kukana madzi, kusindikiza kwambiri kwa mitundu inayi, kusindikiza kwa madontho, ndi zina zotero. Kupanga ndi kugwiritsa ntchito inki yamadzi ku China kunayamba mochedwa, koma kupita patsogolo kwakhala kwachangu, makamaka m'zaka zaposachedwa, zomwe zawonjezera kuchuluka kwa chitukuko mwachangu. Ubwino wa inki yapakhomo wawonjezeka limodzi ndi kuwonjezeka kwa kufunikira kwa inki. Inki, m'njira yachikhalidwe youma pang'onopang'ono, kunyezimira koipa, kusowa kwa kukana madzi, kusindikiza zabodza, ndi zolakwika zina, yakwera kwambiri. Mitengo ya inki yochokera kunja nthawi zambiri imakhala yokwera kwambiri, koma inki yaku China yakhala ikulamulira msika ndi mapangidwe ake okongola komanso otsika mtengo. Mitengo ya inki yochokera kunja nthawi zambiri imakhala yokwera kwambiri, koma inki yaku China yakhala ikulamulira msika ndi mapangidwe ake okongola komanso otsika mtengo.
Taganizirani za Kapangidwe ka Inki Yochokera M'madzi ndi Kuphatikizika Kwake.
Inki yochokera m'madzi imapangidwa ndi utomoni wosungunuka m'madzi, utoto wamakono, zosungunulira, ndi zowonjezera zomwe zaphwanyidwa ndi njira yasayansi yopangira zinthu zosiyanasiyana. Utomoni wosungunuka m'madzi mu inki makamaka umagwira ntchito ngati chinthu cholumikizira, kufalitsa tinthu ta utoto mofanana kuti inki ikhale ndi kuyenda kwina ndikumamatira ku chinthu choyambira kuti inkiyo ipange filimu yofanana pambuyo posindikiza. Mtundu wa inki umatsimikiziridwa makamaka ndi utoto, womwe umafalikira mofanana muzinthu zolumikizira ngati tinthu tating'onoting'ono, ndipo tinthu ta utoto timatha kuyamwa, kuwonetsa, kusinthasintha, ndikutumiza kuwala, zomwe zimawalola kuwonetsa mtundu winawake. Kawirikawiri, utoto uyenera kukhala ndi mtundu wowala bwino, utoto wokwanira komanso mphamvu yophimba, komanso kufalikira kwakukulu. Kuphatikiza apo, kutengera momwe amagwiritsidwira ntchito, amatha kukhala ndi zotsutsana zosiyanasiyana zotupa. Ntchito ya chosungunulira ndikusungunula utomoni kuti inkiyo ikhale ndi madzi pang'ono, kusamutsa kumatha kuchitika bwino panthawi yonse yosindikiza, ndipo kukhuthala ndi magwiridwe antchito a inki zitha kusinthidwa. Chosungunulira mu inki yochokera m'madzi makamaka ndi madzi okhala ndi ethanol pang'ono.
Inki Yochokera M'madzi Imagwiritsidwa Ntchito Kawirikawiri Zowonjezera Monga monga Defoamer, PH Value Stabilizer, Slow drying Agent, ndi zina zotero.
(1) chotsukira fumbiNtchito ya defoamer ndikuletsa ndi kuthetsa kupanga thovu la mpweya. Kawirikawiri, pamene kukhuthala kwa inki yochokera m'madzi kuli kokwera kwambiri, PH ndi yotsika kwambiri, kapena liwiro la makina osindikizira ndi lothamanga kwambiri, zimakhala zosavuta kupanga thovu. Ngati kuchuluka kwa thovu lopangidwa kuli kwakukulu, padzakhala kutuluka kwa mtundu woyera, wosagwirizana wa inki, zomwe zidzakhudza kwambiri mtundu wa zinthu zosindikizidwa.
(2) mankhwala owumitsa pang'onopang'ono.Chowumitsa pang'onopang'ono chingalepheretse ndikuchepetsa liwiro la kuumitsa kwa inki yochokera m'madzi kuti ipewe kuuma kwa inki yomwe ili mu mbale yosindikizira kapena ma anilox rollers ndikuchepetsa kuchuluka kwa zolakwika zosindikizira zomwe zimatsekereza ndikumata. Yang'anirani kuchuluka kwa chowumitsa pang'onopang'ono; nthawi zambiri, kuchuluka konse kwa inki kuyenera kukhala pakati pa 1% ndi 2%. Ngati muwonjezera kwambiri, inki sidzauma bwino, ndipo zosindikizidwazo zidzakhala zomata, zodetsedwa, kapena kutulutsa fungo loipa.
(3) Chokhazikitsa mphamvu ya PH:Chokhazikika cha PH chimagwiritsidwa ntchito makamaka powongolera ndikuwongolera mtengo wa PH wa inki yochokera m'madzi kuti ikhale yokhazikika pakati pa 8.0–9.5. Nthawi yomweyo, imathanso kuwongolera kukhuthala kwa inki yochokera m'madzi ndi kusungunuka kwa inki. Kawirikawiri, kuchuluka koyenera kwa PH kuyenera kuwonjezedwa nthawi iliyonse yosindikizidwa kuti inki yochokera m'madzi ikhale bwino.
Ubwino wa inki yochokera m'madzi
Inki yopangidwa ndi madzi ikukwaniritsa zofunikira zoteteza chilengedwe, chinthucho chili ndi fungo losapsa, losawononga, losakwiyitsa, losaphulika, losavuta kunyamula, lili ndi kuchuluka kwakukulu, mlingo wochepa, kukhuthala kochepa, losinthasintha bwino posindikiza, magwiridwe antchito okhazikika, kulimba bwino potsatira, kuumitsa mwachangu, magwiridwe antchito olimbana ndi madzi, alkali, ndi kukwawa ndi abwino kwambiri; Mapangidwe ovuta osindikiza amathanso kukhala ndi milingo yolemera, mitundu yowala komanso yowala kwambiri, ndi makhalidwe ena. Phindu lalikulu logwiritsa ntchito inki yopangidwa ndi madzi ndikuti imachepetsa kuchuluka kwa zinthu zowononga zachilengedwe (voc) zomwe zimatulutsidwa mumlengalenga, zomwe zimathandiza kukonza mikhalidwe yosindikizira, kupewa kuipitsidwa kwa mpweya, komanso kuchepetsa kwambiri chiopsezo cha moto. Pofuna kukonza bwino chilengedwe, imatha kuchotsa kwathunthu zinthu zina zovulaza zomwe inki yopangidwa ndi zosungunulira ili nazo pa thanzi la anthu, komanso kuipitsidwa komwe kumabwera ndi ma CD. Imagwira ntchito bwino kwambiri posindikiza ndi kulongedza katundu yemwe amafunika kusungidwa aukhondo, monga chakudya ndi mankhwala.
Monga wogulitsa makapu a mapepala ambiri, GFP nthawi zonse yakhala ikudzipereka kugwiritsa ntchito zinthu zosawononga chilengedwe mu katundu wake, kutenga udindo pa chilengedwe komanso thanzi la makasitomala ake. Makapu athu a mapepala amasindikizidwa pogwiritsa ntchito inki yochokera m'madzi, ndipo njira yosindikizira imachitika makapu asanaphimbidwe, kotero akagwiritsidwa ntchito, inki yochokera kunja sidzakhudza khoma lamkati la chikho, zomwe zimateteza thanzi la ogwiritsa ntchito. Chonde pitani ku ulalo wotsatira kuti mudziwe zambiri za makapu athu a mapepala osawononga chilengedwe ndi ntchito zina zokhudzana nazo.
