Ka lipente tse entsoeng ka metsi, li-emulsions, thickeners, dispersants, solvents, leveling agents li ka fokotsa tsitsipano ea holim'a pente, 'me ha ho fokotseha hona ho sa lekana, o ka khetha moemeli oa substrate wetting.

Ka kopo elelloa hore khetho e ntle ea substrate wetting agent e ka ntlafatsa thepa ea pente e nang le metsi, kahoo li-agent tse ngata tsa substrate wetting ke li-agent.

Mefuta ea li-agent tsa substrate wetting ke: li-anionic surfactants, nonionic surfactants, polyether-modified polysiloxanes, acetylene diols, joalo-joalo. pente e thehiloeng), hangata e qhibilihang ka metsing, bubble e tlaase le bubble e sa tsitsang, kutloisiso e tlaase ea metsi, 'me e ke ke ea baka mathata a ho tsosolosa le tahlehelo ea ho khomarela.

Li-substrate wetting agents tse sebelisoang ka tloaelo ke li-adducts tsa ethylene oxide (mohlala, mofuta oa polyoxyethylene-nonylphenol), mofuta oa polyorganosilicon le metsoako ea mofuta oa non-ionic fluorocarbon polymer le mefuta e meng, eo fluorocarbon polymer mofuta oa ho kolobisa ho fokotsa tsitsipano ea holim'a metsi ke phello e kholo ka ho fetisisa.

Maikutlo a fosahetseng, a susumetsoang ke papatso, ke hore phello ea ho fokotsa tsitsipano ea holim'a metsi feela e khethoa ha e le bokhoni ba ho hasana ba ho roala holim'a substrate e leng ea bohlokoa haholo, 'me thepa ena e boetse e amana le ho lumellana ha tsamaiso le mokhoa o nepahetseng. tsitsipano e kahodimo.

Bokhoni ba ho hasana ba moemeli oa ho kolobisa bo ka khethoa ka ho lekanya sebaka se hasang sa molumo o fanoeng (0.05 ml) oa pente holim'a substrate e koahetsoeng pele ka mor'a ho eketsa motsoako o fanoeng oa substrate wetting agent penteng.Lisebelisoa tsa ho kolobisa.

Maemong a mangata, boleng ba tsitsipano e tsitsitseng holim'a metsi bo ke ke ba lumellana le bokhoni ba ho koloba ha pente nakong ea kaho, hobane pente e sebakeng sa khatello ea maikutlo nakong ea kaho, 'me ho theola tsitsipano e matla holim'a metsi ka nako ena, ho molemo haholo ho kolobisa.Li-surfactants tsa fluorocarbon haholo-holo li fokotsa tsitsipano ea holim'a metsi, e leng le leng la mabaka a etsang hore tšebeliso ea li-fluorocarbon surfactants e fokotsehe haholo ho feta ea silicones.

Ho khetha solvent e nepahetseng ho ka ba le phello e ntle ea ho kolobisa substrate.Hobane solvent e lumellana le tsamaiso, tsitsipano e matla ea holim'a metsi e tlaase.

Tlhokomelo e khethehileng: haeba moemeli oa ho kolobisa oa substrate o sa khethoa ka nepo, o tla theha lesela le le leng la molek'hule holim'a substrate, kahoo ho lumellana le mokhoa oa ho roala ha ho sa le molemo, ho tla ama ho khomarela.
