I-Dispersants izongezo ezingaphezulu ezisetyenziselwa ukuzinzisa amasuntswana aqinileyo kwimidiya efana ne-adhesives, iipeyinti, iiplastiki kunye neengxube zeplastiki.

Ngaphambili, iingubo zokwaleka ngokusisiseko zazingadingi izinto zokuchitha. Iinkqubo ezifana ne-alkyd kunye nepeyinti ye-nitro ayifuni i-dispersants. I-Disperpers ayizange ibonakale kude kube yipeyinti ye-acrylic resin kunye ne-polyester resin yepeyinti. Oku kuhambelana ngokusondeleyo nokuphuhliswa kwee-pigments, kuba ukusetyenziswa kwee-pigments eziphezulu akukwazi ukuhlukana noncedo lwabasasaza.
I-Dispersants izongezo ezingaphezulu ezisetyenziselwa ukuzinzisa amasuntswana aqinileyo kwimidiya efana ne-adhesives, iipeyinti, iiplastiki kunye neengxube zeplastiki. Esinye isiphelo saso sisityathanga sosombululo esinokuthi sinyibilike kwimidiya eyahlukeneyo ye-dispersion, kwaye esinye isiphelo liqela le-anchoring pigment elinokuthi libhengezwe kumphezulu wemibala eyahlukeneyo kwaye isetyenziselwe ukuguqula ujongano oluqinileyo / olulwelo (i-pigment / isisombululo seresin).

Isisombululo se-resin kufuneka singene kwizithuba phakathi kwe-pigment agglomerates. Zonke ii-pigments zikhona njenge-pigment agglomerates, "ziingqokelela" zamasuntswana e-pigment, ezinomoya kunye nokufuma okuqulethwe kwizithuba zangaphakathi phakathi kwamasuntswana ebala lebala. Iingqungquthela zidibanisana kunye neengqungquthela kunye neekona, kwaye ukusebenzisana phakathi kweengqungquthela kuncinci, ngoko ke le mikhosi inokunqotshwa ngezixhobo eziqhelekileyo zokusabalalisa. Kwelinye icala, ii-aggregates zixinene ngakumbi, kwaye kukho ukudibana ubuso ngobuso phakathi kwamasuntswana e-pigment, ngoko ke kunzima kakhulu ukuwasasaza kumasuntswana aphambili. Ngexesha le-pigment dispersion process yokusila, i-pigment agglomerates ngokuthe ngcembe iba ncinci; imeko efanelekileyo kukufumana amasuntswana aphambili.

Inkqubo yokugaya i-pigment inokwahlulwa ibe ngamanyathelo amathathu alandelayo: inyathelo lokuqala kukumanzisa. Ngaphantsi kokuvuselela, wonke umoya kunye nomswakama phezu kwendawo ye-pigment iyaxoshwa kwaye ithathelwe indawo yisisombululo se-resin. I-disperant iphucula ukumanzi kwe-pigment, ukuguqula i-solid / i-gas interface ibe yinto eqinile / eyomanzi kunye nokuphucula ukusebenza kakuhle kokugaya; Inyathelo lesibini yinkqubo yokugaya ye-pigment yangempela. Ngokusebenzisa impembelelo yamandla omatshini kunye ne-shear force, i-pigment agglomerate yophukile kwaye ubungakanani be-particle buncitshiswe kumasuntswana aphambili. Xa i-pigment ivulwa ngamandla omatshini, i-dispersant iya kubhengeza ngokukhawuleza kwaye isonge amaqhekeza amancinci amancinci; kwinqanaba lesithathu lokugqibela, i-pigment dispersion kufuneka izinzile ngokwaneleyo ukukhusela ukubunjwa kwe-flocculation engalawulwayo.

Ukusetyenziswa kwe-dispersant efanelekileyo kunokugcina i-pigment particles kumgama ofanelekileyo omnye komnye ngaphandle kokubuyisela umnxibelelwano. Kuninzi lwezicelo, imo ezinzileyo ye-deflocculated iyafunwa. Kwezinye izicelo, i-pigment dispersion ingahlala izinzile phantsi kweemeko ezilawulwayo ze-coflocculation. Uncedo lokumanzisa lunokunciphisa umahluko womphezulu woxinzelelo phakathi kwebala kunye nesisombululo seresin, kukhawulezise ukumanzisa kwe-pigment agglomerates yiresin; ukusasaza izixhobo zokwandisa uzinzo lwe-pigment dispersion. Ke ngoko, imveliso efanayo ihlala inemisebenzi yoncedo lokumanzisa kunye nokusasaza.

Ukusasazwa kwe-pigment yinkqubo ukusuka kwi-aggregate ukuya kwindawo esasazekileyo. Njengoko ubungakanani be-particle buncipha kwaye indawo ephezulu iyanda, amandla omhlaba wenkqubo nawo ayanda.
Ekubeni amandla angaphezulu kwenkqubo yinkqubo yokunciphisa ngokuzenzekelayo, ukwanda okucacileyo kwendawo ephezulu, amandla amaninzi afunekayo ukuba asetyenziswe ukusuka ngaphandle ngexesha lenkqubo yokusila, kwaye isiphumo esinamandla sokuzinzisa kwe-dispersant siyadingeka ukuze kugcinwe ukuzinza kwe-dispersion yenkqubo. Ngokubanzi, i-pigments ye-inorganic inobungakanani obukhulu bamasuntswana, iindawo ezisezantsi ezisezantsi, kunye ne-polarity ephezulu yomphezulu, ngoko kulula ukusabalalisa nokuzinzisa; ngelixa ii-pigments ezahlukeneyo ze-organic kunye ne-carbon black inobungakanani bamasuntswana amancinci, iindawo ezinkulu ezingaphezulu, kunye ne-polarity esezantsi, ngoko ke kunzima kakhulu ukuzisasaza nokuzinzisa.

Ngoko ke, i-disperants ikakhulu ibonelela ngeendlela ezintathu zokusebenza: (1) ukuphucula i-pigment yetting kunye nokuphucula ukusebenza kakuhle kokugaya; (2) ukunciphisa i-viscosity kunye nokuphucula ukuhambelana nezinto ezisisiseko, ukuphucula i-gloss, ukugcwala kunye nokungafani komfanekiso, kunye nokuphucula ukuzinza kokugcinwa; (3) ukwandisa amandla e-pigment tinting kunye nokugxila kwi-pigment kunye nokuphucula ukuzinza kombala.

Nanjing Reborn New Materials inikezaukumanzisa dispersant agent yeepeyinti kunye neengubo, kuquka nezinye ezihambelana neDisperbyk.

In inqaku elilandelayo, siya kuphonononga iintlobo ze-disperants ngamaxesha ahlukeneyo kunye nembali yophuhliso lwe-dispersants.
