Kwiipeyinti ezisekelwe emanzini, ii-emulsions, izithambisi-manzi, izinyibilikisi, izinyibilikisi, izinyibilikisi, ii-leveling agents zinokunciphisa uxinzelelo lomphezulu wepeyinti, kwaye xa ezi nciphiso zinganelanga, ungakhetha i-substrate wetting agent.

Nceda uqaphele ukuba ukhetho olufanelekileyo lwe-substrate wetting agent lunokuphucula i-leveling property yepeyinti ephuma emanzini, ngoko ke uninzi lwe-substrate wetting agents zi-leveling agents.

Iindidi zee-substrate wetting agents zezi: ii-anionic surfactants, ii-nonionic surfactants, ii-polysiloxanes eziguqulwe yi-polyether, ii-acetylene diols, njl. Iimfuno ezisisiseko zee-substrate wetting agents kukusebenza kakuhle ekunciphiseni uxinzelelo lomphezulu, ukuhambelana kakuhle kwenkqubo (ingakumbi kwipeyinti esekwe emanzini ekhazimlayo), idla ngokunyibilika emanzini, ii-bubble eziphantsi kunye nee-bubble ezizinzileyo, uvakalelo oluphantsi emanzini, kwaye aziyi kubangela iingxaki zokuphinda zifakelwe kunye nokulahleka kokunamathela.

Ii-arhente zokumanzisa ze-substrate ezisetyenziswa rhoqo zii-ethylene oxide adducts (umzekelo, uhlobo lwe-polyoxyethylene-nonylphenol), uhlobo lwe-polyorganosilicon kunye nee-non-ionic fluorocarbon polymer type compounds kunye nezinye iintlobo, apho i-agent yokumanzisa ye-fluorocarbon polymer type ukunciphisa uxinzelelo lomphezulu yeyona nto ibalulekileyo.

Ingcamango ephosakeleyo, ephenjelelwa yintengiso, kukuba isiphumo sokunciphisa uxinzelelo lomphezulu kuphela simiselwa xa kukukwazi ukusasazeka kwengubo kwi-substrate okubaluleke ngakumbi, kwaye olu phawu lukwanxulumene nokuhambelana kwenkqubo kunye noxinzelelo lomphezulu olufanelekileyo.

Amandla okusasazeka kwesixhobo sokumanzisa anokufunyanwa ngokulinganisa indawo yokusasazeka yomthamo othile (0.05 ml) wepeyinti kwisiseko esisele sigqunywe emva kokongeza uxinaniso oluthile lwesixhobo sokumanzisa kwisiseko kwipeyinti. Iiarhente zokumanzisa.

Kwiimeko ezininzi, ixabiso loxinzelelo lomphezulu oluzinzileyo alinakuhambelana nokukwazi ukumanzisa kwepeyinti ngexesha lokwakhiwa, kuba ipeyinti ikwindawo yoxinzelelo ngexesha lokwakhiwa, kwaye okukhona uxinzelelo lomphezulu oluguquguqukayo luphantsi ngeli xesha, kokukhona kuluncedo ngakumbi ekumanziseni. Ii-surfactants ze-Fluorocarbon zinciphisa uxinzelelo lomphezulu oluzinzileyo, nto leyo yenye yezizathu zokuba ukusetyenziswa kwee-surfactants ze-fluorocarbon kunganelanga kakhulu kunee-silicones.

Ukukhetha isinyibilikisi esifanelekileyo kunokuba nefuthe elihle lokumanzisa i-substrate. Ngenxa yokuba isinyibilikisi siyahambelana nenkqubo, uxinzelelo lomphezulu oluguqukayo luphantsi.

Ingqwalasela ekhethekileyo: ukuba i-substrate wetting agent ayikhethwanga ngokufanelekileyo, iya kwenza umaleko omnye we-molecular kwi-substrate, ngaloo ndlela ukuhambelana nenkqubo yokugquma akusekho kuhle, nto leyo eya kuchaphazela ukunamathela.

Izinto ezahlukeneyo zokumanzisa zingaxutywa ukuze kusonjululwe ukumanzisa okuntsonkothileyo kwe-substrate.
