Utoto wa mafakitale wopangidwa ndi madzi umagwiritsa ntchito madzi makamaka ngati chosungunula. Mosiyana ndi utoto wopangidwa ndi mafuta, utoto wa mafakitale wopangidwa ndi madzi umadziwika kuti sufunika zinthu zosungunulira monga zotsukira ndi zothina. Chifukwa chakuti zokutira za mafakitale zopangidwa ndi madzi sizimayaka moto komanso zimaphulika, zimakhala zathanzi komanso zobiriwira, komanso zimakhala ndi VOC yochepa, zimagwiritsidwa ntchito kwambiri m'mafakitale monga milatho, nyumba zachitsulo, magalimoto amalonda, makina omanga, mphamvu ya mphepo ya petrochemical ndi zina.

Opanga utoto wopangidwa ndi madzi nthawi zambiri amagawa utoto wopangidwa ndi madzi m'mafakitale m'mitundu yosiyanasiyana: utoto wopangidwa ndi madzi wa alkyd, utoto wopangidwa ndi madzi wa acrylic, utoto wopangidwa ndi madzi wa epoxy, utoto wopangidwa ndi madzi wa acrylic, utoto wopangidwa ndi madzi wa acrylic, ndi utoto wopangidwa ndi madzi wa inorganic zinc. Ukhoza kugawidwa m'mitundu yosiyanasiyana yodziuma yokha, mtundu wophikira ndi mtundu wa dip coating.

Utoto wa alkyd resin wochokera m'madzi uli ndi mawonekedwe ouma mwachangu komanso magwiridwe antchito abwino kwambiri oteteza, ndipo ungagwiritsidwe ntchito pophimba pansi pa zitsulo. Chophimbacho chingagwiritsidwe ntchito pophimba pansi, kuphimba kupopera, kuphimba kupopera ndi njira zina. Mtundu uwu umagwiritsidwa ntchito kwambiri pophimba pansi pa mipando, chassis yamagalimoto, ndi akasupe a masamba agalimoto, ndipo ndi woyenera kwambiri pophimba pamwamba pa chitsulo chotumizidwa kunja.

Mbali yaikulu ya utoto wa acrylic wochokera m'madzi ndi yomatira bwino ndipo sidzakulitsa mtundu wake, koma umakhala wofooka chifukwa cha kutopa komanso mankhwala. Chifukwa cha mtengo wake wotsika komanso kusakhala ndi zinthu zambiri zaukadaulo, umagwiritsidwa ntchito kwambiri pazitsulo zomwe zimakhala ndi kuwala kochepa komanso zokongoletsera zochepa.

Utoto wa epoxy resin wochokera m'madzi ulibe zinthu zovulaza monga benzene, formaldehyde, lead, mercury, ndi zina zotero. Uli ndi zinthu zolimba kwambiri, umamatira mwamphamvu, umalimbana bwino ndi dzimbiri, komanso umateteza bwino kwambiri zinthuzo komanso umateteza kutentha. Kupanga ndi kugwiritsa ntchito kwake ndi komwe kumapangidwira pakali pano.

Utoto wa mafakitale umapangidwa makamaka ndi amino ndi alkyd zochokera m'madzi. Kuwonjezera pa makhalidwe a utoto wochokera m'madzi, utoto uwu wochokera m'madzi uli ndi kuwala kodabwitsa komanso kudzaza, ndipo magwiridwe ake sasiyana ndi amino wamba. Komabe, uyenera kuphikidwa panthawi yomanga, zomwe ndi vuto la mankhwalawa.
