Indima yeI-ejenti ehlakazayo i-MFukunciphisa isikhathi namandla adingekayo ukuqedela inqubo yokusabalalisa, ukuzinzisa ukuhlakazeka kwe-pigment ehlakazekile, ukuguqula izakhiwo ezingaphezulu zezinhlayiya ze-pigment, ukulungisa ukunyakaza kwezinhlayiya ze-pigment, njll.
Ihlanganiswe kulezi zici ezilandelayo:
Nciphisa isikhathi namandla weI-ejenti ehlakazayo i-MFinqubo
Ngokuhambisana, ingaphezulu lezinhlayiya ze-pigment lingaguqulwa ngokushesha lisuka ku-"gas-solid interface" libe "i-liquid-solid interface". Ngaleyo ndlela kunciphisa isikhathi namandla adingekayo ukuze kugaywe.
Yehlisa i-viscosity
Ukusetshenziswa kwe-disperant kunganciphisa i-viscosity futhi kwandise umthamo wokulayisha we-pigment.
Vimbela i-flocculation futhi ubuyele kumaholoholo
Ihlakazeka endaweni ye-pigment, ngokusebenzisa i-electrostatic repulsion noma isithiyo esiqinile ukuze kugwenywe ukukhangana nokuvala, ukuze kwandiswe ukuzinza kwesistimu.
Kuyafaneleka ukubalula ukuthi ukuqina kwezinhlayiya ze-pigment, indawo engaphezulu yendawo ethile enkulu, ukuphakama kwamandla angaphezulu, isidingo samandla aphezulu wokukhangisa.I-ejenti ehlakazayo i-MF, ngakho-ke inani lokusabalalisa lihlobene nekhwalithi yokunamathisela.
Vimbela izinwele ezintantayo
Ngokufanayo nalesi simiso esingenhla, ingqikithi yokuzinza kwe-disperant.
Thuthukisa ukusebenza kombala
Thuthukisa amandla okuthayela, wandise ukuboniswa kombala. Thuthukisa ukugcwala kanye nokungafihli kombala wemvelo, futhi ukhuphule amandla okufihla ama-pigments we-inorganic.
Ithonya ekusebenzeni kwefilimu kapende
I-Dispersant ngeke ishiye ifilimu yepende ngemuva kokwakhiwa kwefilimu, kodwa njengengxenye ehlala njalo yefilimu yepende ikhona kwifilimu yepende, ayinawo umthelela omncane ekusebenzeni kwefilimu yepende.
Umthelela wokumelana namanzi:
Kusukela kumgomo wesenzo wokuhlakazeka, ingqikithi ye-disperant i-surfactant, enezici ze-amphiphilic. Ngakho-ke, i-disperant nakanjani izoba ne-hydrophilic ethile, efilimini yepende inomthelela omkhulu ekuphikisweni kwamanzi.
I-Sv-246h i-superdispersant esekelwe emanzini ingumkhiqizo oguquliwe we-hydrophobic, ifilimu yomile, ngeke ithinte ifilimu ngokwayo ukumelana namanzi.
Umthelela ku-gloss:
I-gloss yendawo yefilimu kapende itholakala ngokuyinhloko ekukhanyeni kokukhanya endaweni yefilimu kapende, futhi isimo esingaphezulu sincike kusayizi wezinhlayiyana zengxenye ngayinye, kanye nesimo sokuhambisana nokusabalalisa.
Ukuhlakazeka okuhlakazekayo, ukuzinza ngokungangabazeki kuwusizo olukhulu ekucwebezeleni kwefilimu kapende. Kodwa futhi kudingeka ucabangele dispersant ngokwayo kanye resin ngokwayo ukuhambisana. Isibonelo, i-SV-246H i-superdispersant esekwe emanzini inokuhambisana okuhle kakhulu kumasistimu e-acrylic asekelwe emanzini, futhi ingakhuphula isicwebezelisi ngo-2-3% uma kuqhathaniswa nezisabalalisi ezivamile ezifana no-755W no-190.
isiphetho
I-Disperant iyisengezo esibaluleke kakhulu ekuhlanganiseni.
Akuhlukile nje kuphela kubasizi abakha ifilimu, isilawuli se-pH sizoguquguquka enqubweni yokomisa; Iphinde yehluke kune-ejenti yokumanzisa, i-ejenti yokukhipha amagwebu kanye ne-ejenti yokujiya.
Ngenxa yokuthi ihlale ikhona efilimini yepende futhi inokuqukethwe okuphezulu, inomthelela omkhulu ekusebenzeni kwefilimu yepende. Ngakho-ke, ukukhethwa nokusetshenziswa kwe-dispersant kusiza kakhulu ekusebenzeni kokugqoka.
