1. Isimiso

Uma i-resin esekelwe emanzini imbozwe ebusweni be-substrate, ingxenye ye-ejenti yokumanzisa ingaphansi kwengubo, ethintana nobuso obuzomanziswa, ingxenye ye-lipophilic inamathela ebusweni obuqinile, kanti iqembu le-hydrophilic lidlulela ngaphandle emanzini. Ukuxhumana phakathi kwamanzi ne-substrate kuba ukuxhumana phakathi kwamanzi neqembu le-hydrophilic le-ejenti yokumanzisa, kwakha isakhiwo se-sandwich ne-ejenti yokumanzisa njengengqimba ephakathi. Yenza kube lula ukusabalalisa isigaba samanzi, ukuze kufezwe injongo yokumanzisa. Enye ingxenye ye-ejenti yokumanzisa esekelwe emanzini ikhona ebusweni boketshezi, iqembu layo le-hydrophilic lidlulela emanzini oketshezi, kanti iqembu le-hydrophobic livezwa emoyeni ukuze lenze ungqimba lwe-monomolecular, olunciphisa ukucindezeleka kobuso bengubo futhi lukhuthaze ukumanzisa okungcono kwengubo.

2. Ulwazi oluthile ekusebenziseni izinto zokumanzisa ezisekelwe emanzini

Ekukhiqizweni kwangempela, uma kucatshangelwa ikhono lokumanzisa le-resin, akufanele kucatshangelwe ubukhulu bokucindezelwa kwayo okumile kuphela, kodwa futhi nobukhulu bokucindezelwa kobuso okuguquguqukayo, ngoba enkambisweni yokumboza i-resin, ngaphansi kwesenzo sokucindezeleka, ngalesi sikhathi. Uma ukucindezelwa kobuso okuguquguqukayo kwehla, kulapho ukumanzisa kuba ngcono khona. Ngalesi sikhathi, lapho i-ejenti yokumanzisa ishesha khona yakha ungqimba olulodwa phezu kobuso be-ejenti, okungukuthi, lapho ukwakheka kwengqimba yama-molecule eqondiswe ngokushesha, kulapho kusiza khona ukumanzisa. I-ejenti yokumanzisa equkethe i-fluorine inciphisa kakhulu ukucindezelwa kobuso okumile, kanti i-ejenti yokumanzisa esekelwe ku-silicone inganciphisa ukucindezelwa kobuso okuguquguqukayo kahle kakhulu. Ngakho-ke, enkambisweni yokusebenzisa okungokoqobo, kubaluleke kakhulu ukukhetha i-ejenti yokumanzisa efanelekile ngokwesimo sangempela.

3. Indima yabasabalalisi abasebenzisa amanzi

Umsebenzi wezihlanzi ezisekelwe emanzini ukusebenzisa izinto zokumanzisa nezokusabalalisa ukunciphisa isikhathi namandla adingekayo ukuqedela inqubo yokuhlakazeka, ukuqinisa ukuhlakazeka kombala ohlakazekile, ukuguqula izakhiwo zangaphezulu zezinhlayiya zombala, nokulungisa ukuhamba kwezinhlayiya zombala. Kuboniswe ngokukhethekile kulezi zici ezilandelayo:

1. Thuthukisa ukukhanya okukhazimulayo futhi wandise umphumela wokulinganisa. Ukukhanya okukhazimulayo empeleni kuncike kakhulu ekusabalaleni kokukhanya ebusweni bengubo (okungukuthi, izinga elithile lokuba yisicaba. Yiqiniso, kuyadingeka ukunquma ukuthi ngabe kuyisicaba ngokwanele ngethuluzi lokuhlola, hhayi nje kuphela inani nesimo sezinhlayiya eziyinhloko, kodwa futhi nendlela yokuhlanganiswa kwazo.), lapho usayizi wezinhlayiya ungaphansi kwengxenye eyodwa kwengxenye yokukhanya kwesigameko (leli nani aliqinisekile), kuzovela njengokukhanya okuphindiwe, futhi ukukhanya ngeke kwande. Ngokufanayo, amandla okumboza athembele ekusabalaleni ukuze anikeze amandla okumboza ayinhloko ngeke ande (ngaphandle kokuthi i-Carbon black imunca kakhulu ukukhanya, khohlwa ngama-pigment e-organic). Qaphela: Ukukhanya kwesigameko kubhekisela ebangeni lokukhanya okubonakalayo futhi ukulinganisa akukuhle; kodwa naka ukunciphisa inani lezinhlayiya eziyinhloko, okunciphisa i-viscosity yesakhiwo, kodwa ukwanda kobuso obuthile kuzonciphisa inani lama-resin amahhala. Ukuthi kukhona iphuzu lokulinganisela akukuhle. Kodwa ngokuvamile, ukulinganisa kwezingcezu zempuphu akukuhle ngangokunokwenzeka.

2. Vimbela umbala ontantayo ekuqhakazeni.

3. Thuthukisa amandla okufaka imibala Qaphela ukuthi amandla okufaka imibala awaphezulu ngangokunokwenzeka ohlelweni lokufaka imibala oluzenzakalelayo.

4. Nciphisa i-viscosity futhi wandise umthwalo we-pigment.

5. Ukunciphisa ukugoba kunje, kodwa uma izinhlayiya zincane, kulapho amandla aphezulu ongaphezulu, futhi

Kudingeka i-dispersant enamandla aphezulu okumunca, kodwa i-dispersant enamandla aphezulu kakhulu okumunca ingabangela imiphumela emibi ekusebenzeni kwefilimu yokumboza.

6. Isizathu sokwandisa ukuzinza kwesitoreji sifana nalokhu okungenhla. Uma ukuzinza kwe-dispersant kunganele, ukuzinza kwesitoreji kuzoba kubi kakhulu (vele, akunankinga esithombeni sakho).

7. Khulisa ukuthuthukiswa kombala, khulisa ukugcwala kombala, khulisa ukucaca (izinhlayiya eziphilayo) noma amandla okufihla (izinhlayiya ezingaphili).
