Amakhemikhali ephepha abhekisela ezinhlobonhlobo zamakhemikhali asetshenziswa enqubweni yokwenza iphepha, igama elivamile lezinsiza. Kubandakanya izinhlobonhlobo zokuqukethwe:
amakhemikhali e-pulping (njengezinsiza zokupheka, ama-deinking agents, njll.)
1. Izinsiza zokupheka: ezisetshenziselwa ukusheshisa isivinini kanye nesivuno sokupheka kwamakhemikhali, ngokuvamile asetshenziswa ngokuvamile ane-anthraquinone ne-quinone derivatives, ama-surfactants nokunye.
2. I-ejenti ye-deinking: Isetshenziselwa ukufaka i-deinking ohlelweni lokugaywa 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 yokushibilika, okokuhlanza, kanye ne-anti-reprecipitant.
amakhemikhali ephepha (njengei-pulpama-sizing agents,i-ejenti yokulinganisa indawonjll.):
1. 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-resin synthetic synthetic sizing agent kanye ne-ejenti ye-pesin esinethayo esebenzayo.
2. I-ejenti yokulinganisa indawo engaphezulu: isetshenziselwa ukulinganisa phezulu kwephepha ukuze kuthuthukiswe amandla angaphezulu ephepha, ukunciphisa impushana, i-lint nezinye izenzakalo, ikakhulukazi isitashi esishintshiwe, njengesitashi esixutshwe ne-oxidized, isitashi acetate, isitashi esixhumene; 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 (njengei-ejenti ye-antifoam, ukugqokaabasizi)
1. i-antifoam ejenti: isetshenziselwa ukudonsa, ukwenza iphepha, ukugqoka kanye nezinye izinqubo zokuqeda amagwebu, izinhlobonhlobo eziyinhloko zemikhono yamalahle noma i-emulsified parafini, i-fatty acid esters, i-carbon alcohols ephansi, ama-silicones, ama-amides nokunye.
2. izinsiza zokugcoba: 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.
