1. Ikhoza kusungunuka ikatenthedwa pamwamba pa 200 ° C, ndipo phulusa limakhala pafupifupi 0.5% likawotchedwa, ndipo sililowerera ndale pambuyo popangidwa kukhala slurry ndi madzi. Koma mamasukidwe akayendedwe ake, zimatengera mlingo wake wa polymerization.
2. Kusungunuka m'madzi kumakhala kofanana ndi kutentha, kutentha kwakukulu kumakhala ndi kusungunuka kochepa, kutentha kochepa kumakhala ndi kusungunuka kwakukulu.
3. Kusungunuka mu chisakanizo cha madzi ndi organic solvents monga methanol, ethanol, ethylene glycol, glycerin ndi acetone.
4. Pamene mchere wachitsulo kapena organic electrolyte ulipo mu njira yake yamadzimadzi, yankho likhoza kukhalabe lokhazikika. Electrolyte ikawonjezedwa mochuluka, gel kapena mpweya udzawonekera.
5. Zochita zapamtunda. Mamolekyu ake ali ndi magulu a hydrophilic ndi magulu a hydrophobic, omwe ali ndi emulsification, chitetezo cha colloid ndi kukhazikika kwa gawo.
6. Kutentha kwa gelation. Pamene njira yamadzimadzi ikukwera ku kutentha kwina (pamwamba pa kutentha kwa gel osakaniza), imakhala yamitambo mpaka itasungunuka kapena kuzizira, zomwe zimapangitsa kuti yankho liwonongeke, koma likhoza kubwerera ku chikhalidwe chake choyambirira ndi kuzizira. Kutentha kumene gelation ndi mpweya zimachitika zimatengera mtundu wa mankhwala, ndende ya yankho ndi mlingo wa kutentha.
7. Phindu la pH ndilokhazikika. Kukhuthala m'madzi sikukhudzidwa mosavuta ndi asidi ndi zamchere. Mukawonjezera kuchuluka kwa alkali, mosasamala kanthu za kutentha kwambiri kapena kutentha kochepa, sizingayambitse kuwonongeka kapena kugawanika kwa unyolo.
8. Njira yothetsera vutoli ikhoza kupanga filimu yowonekera, yolimba komanso yotanuka pamtunda pambuyo poyanika. Ikhoza kukana zosungunulira za organic, mafuta ndi mafuta osiyanasiyana. Sichidzasanduka chikasu pamene chikuwonekera, ndipo sichidzawoneka ming'alu yaubweya. Ikhoza kusungunukanso m'madzi. Ngati formaldehyde iwonjezeredwa ku yankho kapena pambuyo pake ndi formaldehyde, filimuyo imakhala yosasungunuka m'madzi koma imatupa pang'ono.
9. Kukhuthala. Ikhoza kulimbitsa madzi ndi machitidwe opanda madzi, ndipo imakhala ndi ntchito yabwino yotsutsa-sag.
10. Kuchuluka mamasukidwe akayendedwe. Njira yake yamadzimadzi imakhala ndi mphamvu yolumikizana yolimba, yomwe imatha kusintha mphamvu yolumikizana ya simenti, gypsum, utoto, pigment, wallpaper ndi zida zina.
11. Nkhani yoimitsidwa. Angagwiritsidwe ntchito kulamulira coagulation ndi mpweya wa particles olimba.
12. Chitetezo cha colloid kuti chiwonjezere kukhazikika kwake. Itha kuletsa kuphatikizika ndi kuphatikizika kwa madontho ndi ma inki, komanso kupewa kugwa kwamvula.
