iindaba

1. Umgaqo

Xa i-resin esekelwe emanzini ifakwe kumphezulu we-substrate, inxalenye ye-ejenti yokumanzisa iphantsi kwengubo, edibanisa nomphezulu ukuba ifakwe emanzini, i-lipophilic segment ibhengezwa kwindawo eqinile, kunye neqela le-hydrophilic lidlulela ngaphandle emanzini.Uqhagamshelwano phakathi kwamanzi kunye ne-substrate luba lunxibelelwano phakathi kwamanzi kunye neqela le-hydrophilic ye-agent emanzi, okwenza isakhiwo sesandwich kunye ne-agent emanzi njengoluhlu oluphakathi.Yenza kube lula ukusabalalisa isigaba samanzi, ukuze ufezekise injongo yokumanzisa.Enye inxalenye ye-agent yokumanzisa esekelwe emanzini ikhona kumphezulu wolwelo, iqela layo le-hydrophilic lidlulela kumanzi angama-liquid, kwaye iqela le-hydrophobic libonakaliswe emoyeni ukwenza umaleko we-monomolecular, okunciphisa ukuxinana komphezulu we-coating kwaye ikhuthaza ukumanzisa okungcono kwengubo.i-substrate, ukwenzela ukufezekisa injongo yokumanzisa.

2. Amanye amava ekusebenziseni i-agent esekelwe emanzini

Kwimveliso yokwenyani, xa kujongwa amandla okumanzisa i-resin, kungekuphela nje ubungakanani boxinzelelo lomphezulu we-static, kodwa kunye nobungakanani boxinzelelo oluguquguqukayo lomphezulu kufuneka kuthathelwe ingqalelo, kuba kwinkqubo yokugquma i-resin, phantsi kwesenzo soxinzelelo, ngeli xesha Okuye kusezantsi ukutsalwa komphezulu oguqukayo, kokukhona ukumanzisa ngcono.Ngeli xesha, ngokukhawuleza i-arhente yokumanzisa yenza umaleko we-monomolecular kumphezulu wengubo, oko kukuthi, ngokukhawuleza ukubunjwa kwe-molecular layer, ikulungele ngakumbi ukumanzisa.I-arhente yokumanzisa ene-fluorine inciphisa ubukhulu becala i-static surface tension, kunye ne-agent ye-silicone-based based agent inokunciphisa i-dynamic surface tension kakuhle kakhulu.Ngoko ke, kwinkqubo yesicelo esisebenzayo, kubaluleke kakhulu ukukhetha i-agent efanelekileyo yokumanzisa ngokwemeko yangempela.kubalulekile

3. Indima yee-dispersants ezisekelwe emanzini

Umsebenzi we-dispers-based dispersants kukusebenzisa i-agent emanzi kunye ne-dispersing agents ukunciphisa ixesha kunye namandla afunekayo ukugqiba inkqubo yokusabalalisa, ukuzinzisa ukusabalalisa i-pigment dispersion, ukuguqula iipropati ze-pigment particles, kunye nokulungelelanisa ukuhamba kwe-pigment particles.Ibonakaliswe ngokukodwa kule miba ilandelayo:

1. Ukuphucula i-gloss kunye nokwandisa umphumo wokulinganisa.Iglosi eneneni ubukhulu becala ixhomekeke ekusasazekeni kokukhanya kumphezulu wokwaleka (oko kukuthi, umgangatho othile wokucaba. Kakade ke, kuyimfuneko ukugqiba ukuba ithe tyaba ngokwaneleyo ngesixhobo sokuvavanya, hayi kuphela inani kunye nokumila. iinqununu eziphambili, kodwa kunye nendlela yokudibanisa), xa ubukhulu becala bungaphantsi kwe-1/2 yokukhanya kwesiganeko (eli xabiso aliqinisekanga), liya kubonakala njengokukhanya okuchasayo, kwaye i-gloss ayiyi kwanda.Ngokufanayo, amandla okugquma axhomekeke ekusasazekeni ukuze anike amandla okugquma aphambili akayi kunyuka (ngaphandle kokuba iCarbon emnyama ithatha ukukhanya, libala malunga ne-organic pigments).Qaphela: Ukukhanya kwesiganeko kubhekiselele kuluhlu lokukhanya okubonakalayo kwaye umgangatho awulungile;kodwa ubeke ingqalelo ekunciphiseni inani leenqununu eziphambili, ezinciphisa i-viscosity yesakhiwo, kodwa ukwanda kwendawo ethile kuya kunciphisa inani lee-resin zamahhala.Ingaba kukho indawo yokulinganisa ayilungile.Kodwa ngokuqhelekileyo, umgangatho weengubo zomgubo awulungile kangangoko kunokwenzeka.

2. Thintela umbala odadayo ungadubuli.

3. Ukuphucula amandla e-tinting Qaphela ukuba amandla e-tinting akakho phezulu kangangoko kwi-auto toning system.

4. Ukunciphisa i-viscosity kunye nokwandisa ukulayishwa kwe-pigment.

5. Ukunciphisa i-flocculation kunje, kodwa i-particle incinci, iphezulu amandla angaphezulu, kwaye

i-disperant enamandla aphezulu e-adsorption iyafuneka, kodwa i-dispersant enamandla kakhulu e-adsorption ingabangela iziphumo ezibi ekusebenzeni kwefilimu yokugqoka.

6. Isizathu sokwandisa ukuzinza kokugcinwa kufana noku ngasentla.Emva kokuba ukuzinza kwe-dispersant akwanelanga, ukuzinza kokugcinwa kuya kuba kubi (ngokuqinisekileyo, akukho ngxaki kumfanekiso wakho).

7. Ukwandisa ukuphuhliswa kombala, ukwandisa ukugcwala kombala, ukwandisa ukukhanya (i-organic pigments) okanye ukufihla amandla (ii-pigments ze-inorganic).
