Ubwino ndi kuipa kwa inki yochokera kumadzi

Inki yochokera m'madzi, yomwe imagwira ntchito ngati njira yosindikizira, imadziwika chifukwa cha mphamvu zake zoyambira pakupatula zosungunulira za organic, zomwe zimachepetsa kwambiri kutulutsa kwamafuta osakhazikika (VOCs), ndipo motero sizimawononga thanzi la opanga inki kapena thanzi la ogwiritsa ntchito nthawi yomweyo. kulimbikitsa chilengedwe chonse. Wotchedwa inki wochezeka ndi chilengedwe, ubwino wake wa chilengedwe umakhala wosavulaza chilengedwe, chosavulaza anthu, osayaka, komanso otetezeka kwambiri, kuchepetsa kawopsedwe kotsalira pa zinthu zosindikizidwa, kuwongolera njira zoyeretsera zida zosindikizira, komanso kuchepetsa kuopsa kwa moto wolumikizidwa ndi magetsi osasunthika ndi zosungunulira zoyaka, zomwe zimakhala zosindikizira zenizeni "zobiriwira".

Pankhani ya mawonekedwe osindikizira, inki yochokera m'madzi imawonetsa kukhazikika kwapadera, kusawononga mbale zosindikizira, kusavuta kugwiritsa ntchito, kukwanitsa, kumatira kolimba pambuyo pakusindikiza, kukana kwamadzi, komanso kuthamanga kwafupipafupi kuyanika (mpaka 200 metres pa mphindi imodzi). ), yogwiritsidwa ntchito pojambula, flexographic, ndi kusindikiza pazithunzi ndi kuthekera kwakukulu. Ngakhale kuti chinyezi chimachepa pang'onopang'ono chomwe chimapangitsa kuti zowumitsa zotentha komanso kunyowetsanso chifukwa cha chinyezi, nkhaniyi yayankhidwa bwino ndi kupita patsogolo kwaukadaulo.

Kapangidwe ka inki yochokera m'madzi kumaphatikizapo ma emulsion a polima amadzi, ma inki, ma surfactants, madzi, ndi zina zowonjezera. Mwa izi, ma emulsion opangidwa ndi ma polima amadzi, monga acrylic ndi ethylbenzene zotumphukira, amagwira ntchito ngati zonyamulira pigment, kupereka zomatira, kuuma, gloss, kuchuluka kwa kuyanika, kukana abrasion, ndi kukana madzi ku inki, koyenera kwa magawo onse osayamwitsa komanso otsekemera. Ma pigment amachokera ku organic monga phthalocyanine blue ndi lithol red mpaka inorganic monga carbon black ndi titanium dioxide. Ma surfactants amathandizira kuchepetsa kugwedezeka kwapamtunda, kumathandizira kugawa inki pagawo laling'ono, komanso kukhazikika.

Komabe, zovuta za inki zochokera m'madzi zimayenderana ndi kutsika pang'ono, kucheperako, komanso nthawi yowuma pang'onopang'ono. Komabe, ndi luso lazopangapanga monga kupititsa patsogolo kagawo kakang'ono, kupangidwa bwino kwa pigment, ndi njira zamakono zosindikizira, nkhawazi zachepa kwambiri, zomwe zimapangitsa kuti inki yochokera m'madzi ikhale yopikisana kwambiri ndipo, nthawi zambiri, kuposa inki yachikhalidwe yosungunulira pakugwiritsa ntchito. Ngakhale inki yotengera madzi imakhala ndi ndalama zokwera pang'ono, kutengera chilengedwe komanso chitetezo chaumoyo kwa ogwiritsa ntchito, ndalama zoonjezera zimawonedwa ngati ndalama zovomerezeka.
