I-Dispersant (I-Dispersant) iyi-ejenti esebenzayo esebenzisanayo enezindawo ezimbili eziphambene, kokubili i-lipophilic ne-hydrophilic.Izinhlayiya eziqinile neziwuketshezi okunzima ukuzincibilikisa oketshezini, zingase futhi zivimbele ukuxazululwa nokufihlwa kwezinhlayiya futhi zenze i-reagent ye-amphiphilic edingekayo ukuze kumiswe ukumiswa okuzinzile.

Umsebenzi we-disperant ukusebenzisa i-disperant yokumanzisa ukunciphisa isikhathi namandla adingekayo ukuze kuqedelwe inqubo yokusabalalisa, ukuzinzisa ukuhlakazeka kwe-pigment ehlakazekile, ukuguqula izakhiwo ezingaphezulu zezinhlayiya ze-pigment, futhi ulungise ukunyakaza kwezinhlayiya ze-pigment.Ihlanganiswe kulezi zici ezilandelayo:

1. thuthukisa ukucwebezela, ukwandise umphumela wokucwebezela kokulinganisa empeleni okubaluleke kakhulu kuncike endaweni enamathelayo yokuhlakazeka kokukhanya (okungukuthi, flatness ethile kungaba., Yiqiniso, kudingeka anqume ukuthi bushelelezi ngokwanele, hhayi kuphela ucabangele inombolo yezinhlayiya zomdabu, umumo, futhi ucabangele inhlanganisela yazo), lapho usayizi wezinhlayiyana ungaphansi kokukhanya kwesigameko (leli nani aliqiniseki), ukusebenza kokukhanya kwe-refraction, ukucwebezela ngeke kuthuthuke, amandla afanayo ekhava athembele ekuhlakazeni ahlinzeka ngesembozo esikhulu. amandla ngeke ande (ngaphandle carbon black ikakhulukazi ngokumunca ukukhanya, organic pigment ukhohlwe).Qaphela: ukukhanya kwesigameko kubhekise kububanzi bokukhanya okubonakalayo akukuhle;kodwa qaphela ukuthi ukuncipha kwenani langempela lezinhlayiya ukunciphisa i-viscosity yesakhiwo, kodwa ukwanda kwendawo kuzonciphisa inani le-resin yamahhala, kungakhathaliseki ukuthi kukhona iphuzu lokulinganisa, kodwa ukumbozwa kwe-powder jikelele akuyona into encane kakhulu. .

2. ukuvimbela ezintantayo izinwele izimbali.

3. thuthukisa amandla ombala ukuze unake amandla ombala kusistimu yokulungisa umbala othomathikhi akuyona ephakeme kakhulu.

4. Yehlisa i-viscosity futhi wandise inani le-pigment.

5. ukunciphisa i-flocculation kufana nalokhu, kodwa amandla amancane e-particle surface, ephakeme, ayanda amandla e-adsorption we-dispersant, kodwa amandla e-adsorption we-disperant angabangela okubi ekusebenzeni kwefilimu yokumboza.

6. Isizathu sokwandisa ukuzinza kwesitoreji siyefana.Uma amandla okuzinza enganele, ukuzinza kwesitoreji kuba kubi kakhulu (kunjalo, kusuka esithombeni sakho).

7. khulisa ukuboniswa kombala, khulisa ukugcwala kombala, khulisa ukubonakala (i-organic pigment) noma amandla okuvala (i-pigment engaphili).

I-HD605 yokumanzisa i-dipersant isiza ukumanzisa kanye nokuzinzisa i-pigment, ivimbele umbala ontantayo nokuhlala kombala, ukugcina amandla okuvala umbala oqinile namandla ombala ngesikhathi sokugcina, kuyilapho kuqinisekisa inani eliphezulu lombala kanye nezinyathelo ezincane zokugaya.Ngenxa yokuthi lezi zithasiselo zinganciphisa i-viscosity futhi zikhuphukele ekugxilweni kwe-pigment ephakeme kakhulu lapho zihlakazwa, udaka lwe-pigment concentrate olukhiqizwayo lubiza kakhulu.I-HD605 inconywa ukukhiqizwa kwezingulube emanzini.Ngezingubo zamanzi ezimelana nokugqwala, kubuye kube umkhiqizo othandwayo.Ingakwazi ukuhlangabezana nezidingo zamandla aphezulu kakhulu we-optical kanye ne-rheological.Uchungechunge lwe-HD605 luwumkhiqizo okhona wemakethe ojwayelekile ngaphandle kwe-ethoxyalkyl phenol yazo zombili izinhlobo ze-solvent nefomula yamanzi.Kusistimu ye-UV, i-HD605 ifanele zonke izingulube futhi umkhiqizo awuqukethe i-acetoxyalkyl phenol.
