Iintlobo kunye nosetyenziso lweekhemikhali zephepha

Iikhemikhali zamaphepha zibhekisela kwiindidi zeekhemikhali ezisetyenziselwa inkqubo yokwenza iphepha, ixesha eliqhelekileyo labancedisi.Kubandakanya uluhlu olubanzi lomxholo:

iikhemikhali zokucofa (ezifana nezincedisi zokupheka, ii-ejenti ze-deinking, njl.njl.)

Izixhobo zokupheka: ezisetyenziselwa ukukhawulezisa isantya kunye nesivuno sokupheka kweekhemikhali pulping, ezisetyenziswa ngokuqhelekileyo zine-anthraquinone kunye ne-quinone derivatives, i-surfactants njalo njalo.

I-agent ye-Deinking: Isetyenziselwa ukudibanisa kwinkqubo yokuchithwa kwephepha elisetyenzisiweyo kunye nokuphindaphinda kwakhona, okunokuphucula ubumhlophe be-pulp kunye nokuphelisa ukungcola okwahlukeneyo njengamachaphaza e-inki, njl. isicoci, kunye ne-anti-reprecipitant.

iikhemikhali zephepha (ezinje nge-agent yokulinganisa i-pulp, i-arhente yokulinganisa umphezulu, njl.njl.):

I-arhente yokulinganisa i-Pulp: i-arhente yokulinganisa yongezwa kwintlama, ukuze udlale indima yokulinganisa, ngokubanzi i-rosin saponification gum, i-rosin eyomeleziweyo yetshungama, itshungama yerosin esasaziweyo (anionic dispersed rosin gum, cationic dispersed rosin gum), AKD kunye neASA kunye nezinye ezisebenzayo. i-arhente yokulinganisa engathathi hlangothi yokwenziwa, i-agent ye-petroleum resin yokulinganisa njalo njalo.

I-ejenti yokulinganisa umphezulu: isetyenziselwa ukulinganisa umphezulu wephepha ukuphucula amandla omphezulu wephepha, ukunciphisa umgubo, i-lint kunye nezinye izinto, ubukhulu becala isitatshi esilungisiweyo, esifana nesitatshi esixutywe ne-oxidized, isitashi seacetate, isitashi esidityanisiweyo;i-cellulose elungisiweyo, njenge-carboxymethyl cellulose;iipolymers zokwenziwa, ezifana polyvinyl alcohol, polyacrylates, styrene maleic anhydride copolymers, emulsions wax njalo njalo;iipolymer zendalo, ezifana chitosan, gelatin njalo njalo.

iikhemikhali zokucubungula iphepha (ezifana ne-agent ye-antifoam, izinto ezincedisayo zokugquma)

i-agent ye-antifoam: isetyenziselwa i-pulping, i-papermaking, i-coating kunye nezinye iinkqubo zokulahla amagwebu, iindidi eziphambili ze-sleeve yamalahle okanye i-kerosene e-emulsified, i-fatty acid esters, i-carbon alcohols ephantsi, i-silicones, i-amides njalo njalo.

izinto ezincedisayo zokugquma: izinto zokuthambisa, ezifana ne-calcium stearate dispersion;i-preservatives, njenge-isothiazolinone, i-p-chloro-m-toluene;i-dispersing agents, ezifana ne-sodium hexametaphosphate, i-polyacrylate ye-sodium;i-viscosity modifiers, njenge-CMC, i-alkali ene-soluble uplift ye-sodium polyacrylate njalo njalo.

Injongo kukuphucula umgangatho wephepha kunye nokusebenza kakuhle kwemveliso, ukuphucula iimeko zokusebenza, ukunciphisa iindleko zokuvelisa, ukwandisa inzuzo yezoqoqosho kunye nokuphuhlisa iindidi ezintsha zamaphepha.
