I-Dispersant (I-Dispersant) yi-arhente esebenzayo yojongano kunye neepropati ezimbini ezichaseneyo, zombini i-lipophilic kunye ne-hydrophilic.Iziqwenga eziqinileyo kunye nolwelo olunzima ukuchithwa kwi-liquid, lunokuthintela ukuhlaliswa kunye nokudibanisa kweengqungquthela kwaye zenze i-amphiphilic reagent efunekayo ekumisweni okuzinzileyo.

Umsebenzi we-dispersant kukusebenzisa i-wetting dispersant ukunciphisa ixesha kunye namandla afunekayo ukugqiba inkqubo yokusabalalisa, ukuzinzisa ukusabalalisa i-pigment dispersion, ukuguqula iipropati zomphezulu we-pigment particles, kunye nokulungelelanisa ukunyakaza kwee-pigment particles.Ifakwe kule miba ilandelayo:

1. phucula ukukhazimla, ukwandisa isiphumo sokulinganisa i-luster eneneni eyona nto ibalulekileyo ixhomekeke kumphezulu wokugquma wokukhanya okusasazwayo (oko kukuthi, ukuthambeka okuthile kunokuba. inani lamasuntswana emveli, imilo, kwaye uqwalasele indibaniselwano yabo), xa ubungakanani besuntswana bungaphantsi kokukhanya kwesiganeko (eli xabiso aliqinisekanga), ukusebenza kokukhanya kwe-refraction, ukukhazimla akuyi kuphucula, amandla okugquma okufanayo athembele ekusasazekeni amandla akayi kunyuka (ngaphandle kwekhabhoni emnyama kakhulu ngokufunxa ukukhanya, i-organic pigment ilibale).Qaphela: ukukhanya kwesiganeko kubhekiselele kuluhlu lokukhanya okubonakalayo akulunganga;kodwa qaphela ukuba ukuncipha kwenani lokuqala leengqungquthela kukunciphisa i-viscosity yesakhiwo, kodwa ukunyuka komphezulu kuya kunciphisa inani le-resin yamahhala, nokuba kukho indawo yokulinganisa, kodwa i-powder yokugqoka i-powder ayiyona nto ibhetele. .

2. thintela iintyatyambo zeenwele ezinombala odadayo.

3. phucula amandla ombala ukunikela ingqalelo kumandla ombala kwinkqubo yohlengahlengiso lombala oluzenzekelayo ayikho phezulu ngcono.

4. Ukunciphisa i-viscosity kwaye ukwandise inani le-pigment.

5. ukunciphisa i-flocculation kunje, kodwa i-suntswana ye-particle surface energy, iphezulu, iphezulu amandla e-adsorption ye-dispersant, kodwa amandla e-adsorption ye-dispersant angabangela kakubi ukusebenza kwefilimu yokugqoka.

6. Isizathu sokunyusa ukuzinza kokugcinwa kuyafana.Emva kokuba amandla okuzinza akwanele, ukuzinza kokugcina kuba kubi (ngokuqinisekileyo, ukusuka kumfanekiso wakho).

7. ukwandisa umboniso wombala, ukwandisa ukugcwala kombala, ukwandisa ukukhanya (i-organic pigment) okanye ukugquma amandla (i-pigment ye-inorganic).

I-HD605 ye-wetting dispersant inceda ukumanzisa kunye nokuzinzisa i-pigment, ukukhusela umbala ojikelezayo kunye nokuhlaliswa kwe-pigment, ukugcina amandla okugquma i-pigment kunye namandla ombala ngexesha lokugcinwa, ngelixa uqinisekisa ubuninzi bombala kunye namanyathelo amancinci okusila.Ngenxa yokuba ezi zongezo zinokunciphisa i-viscosity kwaye zinyuke ziye kweyona ndawo iphezulu ye-pigment concentration xa isasazwe, i-coating kunye ne-pigment concentrate slurry eveliswayo iyabiza kakhulu.I-HD605 iyacetyiswa ukuba kwenziwe i-pigments emanzini.Kwimigquba enganyangekiyo emanzini, ikwayimveliso ekhethwayo.Iyakwazi ukuhlangabezana neemfuno zamandla aphezulu kunye ne-rheological.Uluhlu lwe-HD605 yimveliso ekhoyo esemgangathweni yemarike ngaphandle kwe-ethoxyalkyl phenol kuzo zombini uhlobo lwe-solvent kunye nefomula yamanzi.Kwinkqubo ye-UV, i-HD605 ifanelekile kuzo zonke ii-pigments kwaye imveliso ayinayo i-acetoxyalkyl phenol.
