Kagwiritsidwe Ntchito
Ntchito yosungunulira: Mafuta osungunuka a hydrocarbon onunkhira pang'ono ndi organic solvent yabwino yomwe imatha kusungunula zinthu zosiyanasiyana monga ma resin ndi mafuta. Mwachitsanzo, mu alkyd resin coatings, ingathandize resin kufalikira mofanana, zomwe zimathandiza kuti kupaka utotowo kukhale ndi madzi abwino komanso zinthu zophimba, zomwe zimakhala zosavuta pa ntchito yomanga monga kutsuka ndi kupopera. Kuwongolera liwiro louma: Kuchuluka kwake kwa nthunzi kumakhala kocheperako ndipo kumatha kusintha nthawi youma ya kupaka utoto. Pa kupaka utoto wina komwe kumafunika kupanga filimu powumitsa mkati mwa nthawi inayake, mafuta osungunuka a hydrocarbon onunkhira pang'ono amatha kuonetsetsa kuti kupaka utotowo kuuma mkati mwa nthawi yoyenera, kuti kupaka utotowo kupange zinthu zabwino zakuthupi, monga kuuma ndi kunyezimira. Mu nitrocellulose lacquers, imathandiza kusungunula nitrocellulose ndikupanga filimu yofanana, komanso imatha kuwongolera liwiro louma la lacquer kuti ipewe khalidwe loipa la kupaka utoto chifukwa cha kuumitsa mwachangu kwambiri. Kusungunuka kwa inki: Monga inki diluent, mafuta osungunuka a hydrocarbon onunkhira pang'ono amatha kuchepetsa kukhuthala kwa inki, zomwe zimapangitsa kuti ikhale yogwirizana bwino ndi zofunikira za zida zosindikizira. Mwachitsanzo, mu inki yosindikizira ya offset, mafuta oyenera osungunulira amatha kusintha mawonekedwe a inki, zomwe zimathandiza kuti inki isamutsidwe bwino kuchokera pa mbale yosindikizira kupita ku zinthu zosindikizira monga mapepala, kuonetsetsa kuti mitundu yosindikizirayo ndi yowala komanso yowala. Kusungunula ma resini ndi utoto: Kungathe kusungunula zigawo za resini mu inki ndikupangitsa utotowo kufalikira mofanana. Izi ndizofunikira kwambiri pakusindikiza mitundu yapamwamba kwambiri, chifukwa pokhapokha utotowo ukagawidwa mofanana, mitunduyo imatha kubwerezedwanso molondola ndikupeza zotsatira zabwino kwambiri zosindikiza.
Kulongedza ndi Kutumiza
Kulongedza: 200kg/ng'oma kapena malinga ndi zomwe makasitomala amafuna.
Kutumiza: ndi mankhwala wamba ndipo amatha kutumizidwa ndi sitima, nyanja ndi mpweya.
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
