Mumvura-based pendi, emulsions, thickeners, dispersants, solvents, leveling agents vanogona kuderedza kushushikana kwependi, uye kana kuderedza uku kusina kukwana, unogona kusarudza substrate wetting agent.

Ndokumbira utarise kuti sarudzo yakanaka ye substrate wetting agent inogona kuvandudza chivakwa chependi yemvura, saka akawanda substrate wetting agents ari kuyera maajenti.

Mhando dze substrate wetting agents ndeidzi: anionic surfactants, nonionic surfactants, polyether-modified polysiloxanes, acetylene diols, etc. Izvo zvinodikanwa zve substrate wetting agents zvinonyanya kushanda mukuderedza tension yepasi, good system kuenderana (kunyanya pamvura inopenya-inopenya). based pendi), kazhinji inonyungudika mumvura, yakaderera bubble uye isina kugadzikana bubble, yakaderera senitivity kumvura, uye haizokonzerese matambudziko ekudzoreredza uye kurasikirwa kwekunamatira.

Inowanzo shandiswa substrate wetting agents ndeye ethylene oxide adducts (somuenzaniso, polyoxyethylene-nonylphenol type), polyorganosilicon mhando uye isiri-ionic fluorocarbon polymer mhando makomboni uye mamwe marudzi, ayo fluorocarbon polymer mhando wetting agent kuderedza pamusoro tension ndiyo inonyanya kukosha.

Pfungwa isiriyo, inopesvedzerwa nekushambadzira, ndeyekuti mhedzisiro yekudzikisa kushushikana kwepasi chete inotarwa kana iri kugona kupararira kwejasi pane substrate iyo inonyanya kukosha, uye ichi chivakwa chine hukama zvakare nekuenderana kwehurongwa uye kwakakodzera. kushushikana kwepamusoro.

Kugona kupararira kwemugadziri wekunyorova kunogona kutariswa nekuyera nzvimbo inopararira yevhoriyamu yakapihwa (0.05 ml) yepende pane pre-yakavharwa substrate mushure mekuwedzera yakapihwa fungidziro ye substrate wetting agent kupende.Wetting agents.

Muzviitiko zvakawanda, kukosha kweiyo static surface tension haigone kuenderana nekunyorova kwepende panguva yekuvaka, nekuti pendi iri munzvimbo yekushushikana panguva yekuvaka, uye kuderera kweiyo dynamic surface tension panguva ino, inonyanya kubatsira pakunyorova.Fluorocarbon surfactants inonyanya kuderedza static surface tension, chinova chimwe chezvikonzero nei kushandiswa kwefluorocarbon surfactants kuri kushoma zvikuru kupfuura kwesilicones.

Kusarudza iyo yakakodzera solvent inogona zvakare kuve yakanaka substrate wetting athari.Nekuti iyo solvent inoenderana nehurongwa, iyo dynamic surface tension yakaderera.

Kunyanya kutarisisa: kana iyo substrate wetting agent isina kusarudzwa nemazvo, inoumba imwe chete molecular layer pane substrate, saka kuenderana neiyo coating system haina kunaka zvakare, izvo zvinokanganisa kunamatira.

Zvinoverengeka zvakasiyana wetting agents zvinogona kusanganiswa kugadzirisa zvakanyanya kuoma substrate wetting.
