I-arhente yokusasaza i-NNOisetyenziswa ngokubanzi kwintsimi yeekhemikhali zokusasazwa, oko kukuthi, ipeyinti, i-inki kunye nezinye i-pigment paste yokucola. Ukongeza, ukongeza i-dispersant kwi-resin okanye i-emulsion inokuphucula ukusebenza komzimba oyintloko. Umsebenzi oyintloko kukunciphisa umqhaphu, ukuthintela ukucwila kunye nokunceda ukusabalalisa. Iimpawu ezintathu ziimpawu ezibalulekileyo ze-disapersants kwaye ziqhele ukusetyenziswa ukuchongaI-arhente yokusasaza i-NNO!
Okokuqala, ukunciphisa i-viscosity kwaye ukwandise umthwalo we-pigment. Ukusebenzisa ngokufanelekileyoI-arhente yokusasaza i-NNO, i-paste viscosity iya kuncitshiswa kakhulu. Isiphumo kukwandisa umthwalo we-pigment, ukuphucula imveliso kudlala indima enhle.
Okwesibini, abantu abaninzi abanciphisa ihlwili kunye nokuphucula ukwakhiwa kobunjineli kunye nokusebenza baya kuqhuba iimvavanyo zophando xa bevavanya i-thickeners. I-disperant collocation engafanelekanga, ukubamba umnwe kunye neendawo ezingachukunyiswanga ziya kubonakala umahluko ocacileyo wombala, amandla ombala we-pigment ekhunisiweyo aya kuncitshiswa, okukhokelela kubunzima bokwakha i-toner kunye nepeyinti. Ukuxinana kwamadama ombala nako kunokujongwa ngovavanyo lwepleyiti yokuqukuqela.
Okwesithathu, ukuphucula ukungafihli okanye ukugubungela. Kwipeyinti, ngakumbi i-paste ecacileyo, ingcono. Kwipeyinti eqhelekileyo, ukuphakama kokugquma kwengca enemibala, kungcono. Enyanisweni, inento yokwenza nobukhulu bebala. Ezinye iinkcukacha zibonisa ukuba ngaphandle kwesalathiso se-refractive, ukuhanjiswa kobungakanani bepeyinti yepeyinti yenye into ebalulekileyo yokungafihli. Njengoko ubungakanani bamasuntswana bukhula, ukukwazi ukusasaza ukukhanya kuqala ukuncipha njengoko kunyuka. Olu buchule lokusasaza ukukhanya luya kwandisa amandla okugcoba kwe-pigment, xa amandla okusasaza eqinile, kwaye ukuba ubungakanani be-particle buqhubeka bukhula, amandla okugqoka aya kuncipha. Nangona kunjalo, ukuba ubungakanani be-pigment particle bungaphantsi kwexabiso elithile, ukukhanya kuya kwanda njengoko ubungakanani be-particle buyancipha. I-Dispersant ayikwazi ukutshintsha iimpawu ze-pigment ngokwayo, kodwa inokulawula ukusabalalisa ubungakanani be-pigment ye-pigment, ukuphumeza umphumo ofanelekileyo wombala.
Yintoni emanzisa i-dispersant, i-disperant yokumanzisa luhlobo lwe-surfactant ene-hydrophilic kunye ne-lipophilic. Ngokukodwa i-insoluble kwi-liquids, isixhobo sinokusasaza ngokulinganayo amasuntswana aqinileyo kwii-pigments eziphilayo, ukukhusela amaqhekeza aqinileyo ekuhlaliseni kunye nokudibanisa ukwenza ii-agent ezifunekayo ukuzinzisa ukumiswa.
Ke ingaba i-disperant yakho yokumanzisa ijongeka njani?
Ukuba yinto ekunokwenzeka ukuba ifunxe izinto eziqinileyo emanzini. Nciphisa ukutsalwa komphezulu okanye ukudityaniswa kobuso ukuze amanzi asasazeke phezu okanye angene kumphezulu wemathiriyeli eqinileyo, ngaloo ndlela umanzisa imathiriyeli eqinileyo. Kwaye ngokuqhelekileyo i-arhente esebenzayo, njengesepha, ioli ye-sulfonated, umgubo kunye nokunye. Ungasebenzisa kwakhona i-soy lecithin, i-acetylene, i-mercaptan, i-mercaptan acetal, njl.
Zombini zichithachitha amanzi
1. I-Adsorb kumphezulu wamasuntswana aqinileyo ukwenza umphezulu okhutshiweyo wamasuntswana aqinileyo umanzi.
2. Umphezulu wamasuntswana aqinileyo wenza umaleko we-adsorption ukwandisa intlawulo kumphezulu wamasuntswana aqinileyo kunye nokuphucula amandla okusabela phakathi kwamasuntswana enza imiqobo emacala amathathu.
3. Yenza umphezulu weengqungquthela eziqinileyo ukwenza isakhiwo se-bilayer, umaleko wangaphandle wamanzi adibeneyo unobudlelwane obuqinileyo, ukwandisa iqondo leengqungquthela eziqinileyo ezimanzi ngamanzi. Amasuntswana aqinileyo ahlukaniswe yi-electrostatic repulsion.
4. Inkqubo efanayo, ukuphucula ukusebenza kokunqunyanyiswa, akukho mvula, iipropati zomzimba kunye neekhemikhali zenkqubo yonke ziyafana.
