I-Disperant iwubufakazi bomswakama, impahla yokuxhuma engangenisi kanye nezinto ezinhle zokubopha, uhlobo lokuqinisa impushana kanye nohlobo lokulibaziseka kuyimpushana empunga.I-ejenti ehlakazayo i-NNOyahlukaniswa yaba amapharafini, insipho yensimbi, ama-wax amangqamuzana aphansi, ama-fatty acids, ama-aliphatic amide nama-ester. I-Dispersant iyisengezo sokugqoka, esingathuthukisa isicwebezelisi sokugqoka, ukuvimbela ukuqhakaza kwekhanda elinemibala emibili, ukunciphisa i-viscosity, ukwandisa umthamo wokulayisha we-pigment nokunye. Ngakho-ke i-disperant inamuphi umphumela ekunambeni?

Indima yeI-ejenti ehlakazayo i-NNOukusebenzisa i-dispersant yokumanzisa ukunciphisa isikhathi namandla adingekayo ukuze uqedele inqubo yokuhlakazwa, uzinzise ukuhlakazeka kwe-pigment ehlakazekile, uguqule izici ezingaphezulu zezinhlayiya ze-pigment, ulungise ukunyakaza kwezinhlayiya ze-pigment. Ngokuvamile kubonakala kulezi zici ezilandelayo:

1, umthelela weglosi:

Uma isicwebezelisi sikapende siphezulu, izinhlayiya azikwazi ukudlula ama-microns angu-5, uyinki awukwazi ukudlula i-micron engu-1, ama-polymer dispersants anganciphisa upende owenziwe yizinhlayiya ezinkulu, ukuze kuthuthukiswe ukucwebezela kopende.

2. Umthelela ekukhanyeni:

Ukuphakama kokucaca kopende, kuba lula ukubukeka kwangaphansi, kuyanda ukumbozwa, futhi kunamandla ukumbozwa ngaphansi. Ama-dispersants angenza ukusatshalaliswa kwezinhlayiya zokugqoka kufane futhi kube mncane, ukuze ukugqoka kubonakale obala.

3. Umthelela ekusebenzisaneni:

Ngokuhambisana okuhle, abakhiqizi bezingubo zokugqoka bangakhiqiza izinhlobonhlobo zemikhiqizo ye-resin Uhlelo lokusabalalisa,I-ejenti ehlakazayo i-NNOinganweba ububanzi bokusetshenziswa kopende, ibalulekile ekukhiqizeni upende onemibala exubile.

4. Umthelela ekulevelini:

Upende wokuhlobisa ngokuvamile ungabona uphawu lwebhulashi lapho u-stuccoing, lokhu upende awunalo izinga locansi. Ukusebenzisa ama-disperants kungaqhubeka nokuzinzisa izinhlayiya ze-pigment futhi kuthuthukise uketshezi.

5. Umthelela kokuphumayo:

Okukhiphayo inani likapende noyinki okhiqizwa inqubo. Ama-dispersants angakhuphula ukukhiqizwa kopende ngokwandisa ukugxila kwe-pigment. Ukwengezwa okufanele kwe-polymer dispersant kunganciphisa i-viscosity futhi kwandise okuqukethwe kwe-pigment ku-slurry abrasive, ngaleyo ndlela kwandise isivuno.
