Zovala zamadzi
SYSTEM Kapangidwe kamangidwe
Utoto wopangidwa ndi madzi ndimadzimadzi owoneka bwino opangidwa ndi utomoni, kapena mafuta, kapena emulsion, wophatikiza zowonjezera zoyenera, komanso zokonzedwa ndi organic sol sol kapena madzi. Kugwiritsa ntchito bwino penti yochokera kumadzi kumakhalanso ndi zinthu zabwino zogwiritsira ntchito, mphamvu yobisala yabwino, zomatira zamakanema zolimba, malo abwino osungira madzi ndi zina. Ma cellulose ether ndi zida zabwino kwambiri zopangira zinthuzi.
Madzi osunga madzi a cellulose ethers amapereka zabwino kwambiri zokutira zovala zakufunda, makamaka zokutira PVC zapamwamba, komanso zophimba zakamafuta. Samayenda; kukhathamiritsa kwake kwakukulu kumachepetsa kuchuluka komwe kumagwiritsidwa ntchito, kumapangitsa kuti chuma chizipanga komanso kusintha magwiridwe antchito. Kuyimitsidwa. Makhalidwe abwino kwambiri mu utoto amakhala ndi utoto wokwanira bwino; malo okhetsedwa, amakhala ndi mayendedwe abwino kwambiri ndipo alibe zopendekera; yosavuta kufalikira pamtunda wamtali pakati pa burashi ndi mipendero yama-rolling, yosavuta kutsatira; pamapeto pake, utoto utagwiritsidwa ntchito, ndikosavuta kufalikira pagawo lapansi. Maso amtunduwu amabwezeretsedwa atamaliza, ndipo utotoyo umayamba kutulutsa.
Pambuyo pakuthandizira koyenera pamtunda, ma ethers a Maxcellulose amatha kuteteza ku agglomeration nthawi yachinyengo, omwazika kwathunthu, nthawi yokwanira yosungunuka komanso kukwera kwa mamasukidwe akayendedwe kungathandize kuti ntchito yopanga ikhale; Mitengo yosinthidwa ya Maxcellulose imakhalanso ndi zinthu zabwino zotsutsana ndi mafangasi, imapereka nthawi yokwanira yosungira utoto, kupewa kwa pigment ndi kudzaza matope.
