Mu utoto wamadzi, emulsions, thickeners, dispersants, solvents, leveling agents amatha kuchepetsa kugwedezeka kwa utoto, ndipo pamene kuchepetsedwa sikukwanira, mukhoza kusankha gawo lapansi wetting wothandizira.

Chonde dziwani kuti kusankha kwabwino kwa chonyowetsa gawo lapansi kumatha kukweza mawonekedwe a penti yopangidwa ndi madzi, kotero kuti zonyowetsa zapansi panthaka zambiri ndizothandizira.

Mitundu ya wothira gawo lapansi ndi: anionic surfactants, nonionic surfactants, polyether-modified polysiloxanes, acetylene diols, ndi zina zotero. utoto wokhazikika), womwe nthawi zambiri umasungunuka m'madzi, kuwira pang'ono komanso kuwira kosakhazikika, kukhudzika kochepa kwamadzi, ndipo sikungayambitse mavuto obwezeretsanso ndi kutayika kwa zomatira.

Ambiri ntchito gawo lapansi wetting wothandizila ndi ethylene okusayidi adducts (mwachitsanzo, polyoxyethylene-nonylphenol mtundu), polyorganosilicon mtundu ndi sanali ionic fluorocarbon polima mtundu mankhwala ndi mitundu ina, amene fluorocarbon polima mtundu wetting wothandizila kuchepetsa kukangana pamwamba ndi zotsatira kwambiri.

Lingaliro lolakwika, lokhudzidwa ndi malonda, ndiloti zotsatira zochepetsera kugwedezeka pamwamba pawokha zimatsimikiziridwa pamene kufalikira kwa zokutira pa gawo lapansi ndilofunika kwambiri, ndipo katunduyu akugwirizananso ndi kugwirizana kwa dongosolo ndi zoyenera. kukangana pamwamba.

Kutha kufalikira kwa chonyowetsa kungadziwike poyesa malo ofalikira a voliyumu yomwe yaperekedwa (0.05 ml) ya utoto pagawo lophimbidwa kale pambuyo powonjezera kuchuluka kwa gawo lapansi kunyowetsa pa utoto.Wonyowetsa wothandizira.

Nthawi zambiri, mtengo wa kugwedezeka kwa static pamwamba sungathe kufanana ndi mphamvu yonyowetsa utoto panthawi yomanga, chifukwa utoto umakhala m'malo opanikizika panthawi yomanga, ndipo kutsika kwamphamvu kwapamtunda panthawiyi, kumakhala kopindulitsa kwambiri pakunyowetsa.Ma surfactants a fluorocarbon makamaka amachepetsa kugwedezeka kwa pamwamba, chomwe ndi chimodzi mwa zifukwa zomwe kugwiritsira ntchito kwa fluorocarbon surfactants kumakhala kochepa kwambiri kusiyana ndi silicones.

Kusankha chosungunulira choyenera kungakhalenso ndi zotsatira zabwino zonyowetsa gawo lapansi.Chifukwa zosungunulira zimagwirizana ndi dongosolo, kugwedezeka kwamphamvu kwapamwamba kumakhala kochepa.

Chisamaliro chapadera: ngati gawo lapansi lonyowetsa silinasankhidwe bwino, lipanga gawo limodzi la maselo pagawo lapansi, motero kugwirizana ndi dongosolo lopaka utoto sikulinso bwino, zomwe zidzakhudza kumamatira.

Mitundu ingapo yonyowetsa ingasakanizidwe kuti ithetse kunyowetsa kwa gawo lapansi.
