Izinhlobo kanye nokusetshenziswa kwamakhemikhali ephepha

Amakhemikhali ephepha abhekisela ezinhlobonhlobo zamakhemikhali asetshenziswa enqubweni yokwenza iphepha, igama elivamile lezinsiza. Kubandakanya izinhlobonhlobo zokuqukethwe:

amakhemikhali e-pulping (njengezinsiza zokupheka, ama-deinking agents, njll.)

Izinsiza zokupheka: ezisetshenziselwa ukusheshisa isivinini kanye nesivuno sokupheka kwamakhemikhali e-pulping, ngokuvamile asetshenziswa ngokuvamile ane-anthraquinone ne-quinone derivatives, ama-surfactants nokunye.

I-ejenti ye-Deinking: Isetshenziselwa ukuhlanganisa inqubo yokugaywa kabusha kwamaphepha kanye nokuphinda kudonswe kabusha, okungathuthukisa ubumhlophe be-pulp futhi kuqede ukungcola okuhlukahlukene njengamachashazi kayinki, njll. Ikakhulukazi iqukethe i-surfactant, i-ejenti ehlanganisayo, i-ejenti emhlophe, okokuhlanza, kanye nesinqamuleli.

amakhemikhali ephepha (njengama-ejenti okulinganisa ama-pulp, i-ejenti yokulinganisa indawo, njll.):

I-ejenti yokulinganisa i-Pulp: i-ejenti yokulinganisa ingezwe ku-pulp, ukuze kudlale indima yokulinganisa, ngokuvamile i-rosin saponification gum, inhlaka ye-rosin eqinisiwe, inhlaka ye-rosin ehlakaziwe (i-anionic ehlakazekile i-rosin gum, i-cationic dispersed rosin gum), i-AKD ne-ASA kanye nenye i-ejenti yokwenziwa yokulinganisa engathathi hlangothi esebenzayo e-petrolegent.

I-ejenti yokulinganisa ingaphezulu: isetshenziselwa ukulinganisa phezulu kwephepha ukuze kuthuthukiswe amandla ephepha, ukunciphisa impushana, i-lint nezinye izenzakalo, ikakhulukazi isitashi esishintshiwe, njengesitashi esixutshwe ne-oxidized, isitashi acetate, isitashi esixutshwe; i-cellulose eguquliwe, njenge-carboxymethyl cellulose; polymers zokwenziwa, ezifana polyvinyl utshwala, polyacrylates, styrene maleic anhydride copolymers, emulsion wax nokunye; i-polymer yemvelo, njenge-chitosan, i-gelatin njalonjalo.

amakhemikhali okucubungula amaphepha (njenge-ejenti ye-antifoam, izinsiza zokugqoka)

i-antifoam ejenti: isetshenziselwa ukudonsa, ukwenza iphepha, ukugqoka nezinye izinqubo zokuqeda amagwebu, izinhlobonhlobo eziyinhloko zemikhono yamalahle noma i-emulsified parafini, i-fatty acid esters, i-carbon alcohols ephansi, ama-silicones, ama-amide nokunye.

ama-coating ama-axiliary: izinto zokugcoba, njenge-calcium stearate dispersion; ama-preservatives, njenge-isothiazolinone, i-p-chloro-m-toluene; ama-agent ahlakazayo, njenge-sodium hexametaphosphate, i-sodium polyacrylate; i-viscosity modifiers, njenge-CMC, i-alkali encibilikayo iphakamisa i-polyacrylate ye-sodium nokunye.

Inhloso ukuthuthukisa ikhwalithi yamaphepha kanye nokusebenza kahle kokukhiqiza, ukuthuthukisa izimo zokusebenza, ukunciphisa izindleko zokukhiqiza, ukwandisa izinzuzo zomnotho kanye nokuthuthukisa izinhlobo ezintsha zephepha.
