Ituaiga ma le Fa'aogaina o vaila'au pepa

O vailaʻau pepa e faʻatatau i vailaʻau eseese o loʻo faʻaaogaina i le faiga o pepa, o le faaupuga lautele a ausilali. E aofia ai le tele o mea e aofia ai:

vaila'au fa'apalapala (e pei o fesoasoani kuka, vaila'au fa'ainu, ma isi)

Fesoasoani kuka: faʻaaogaina e faʻavavevave ai le saoasaoa ma le gaosiga o le kulimi pulping kuka, e masani ona faʻaaogaina e masani ona i ai le anthraquinone ma le quinone derivatives, surfactants ma isi.

Deinking agent: E faʻaaogaina mo le deinking i le faagasologa o le toe faʻaaogaina o pepa otaota ma le toe faʻaleleia, lea e mafai ona faʻaleleia ai le paʻepaʻe o le pulupulu ma faʻaumatia mea leaga eseese e pei o togitogi vaitusi, ma isi.

vaila'au pepa (e pei o mea e fa'apipi'i ai le pulupulu, su'esu'ega fa'apipi'i luga, ma isi mea):

Pulp sizing agent: sizing agent faaopoopo i le pulp, ina ia mafai ona faia le matafaioi o le sizing, e masani lava rosin saponification gum, faʻamalosia rosin gum, dispersed rosin gum (anionic dispersed rosin gum, cationic dispersed rosin gum), AKD ma ASA ma isi mea faʻapipiʻi synthetic sizing agent, suauu resin sizing agent ma isi.

Su'esu'ega fa'apipi'i: fa'aaogaina mo le fa'avasegaina o luga o pepa e fa'aleleia atili ai le malosi o le pepa, fa'aitiitia le pa'u, lint ma isi mea fa'apitoa, fa'atosina fa'alelei, e pei o le masoa oxidized, starch acetate, crosslinked starch; cellulose suia, e pei o le carboxymethyl cellulose; polymers synthetic, e pei o le polyvinyl alcohol, polyacrylates, styrene maleic anhydride copolymers, wax emulsions ma isi; polymer masani, pei o chitosan, gelatin ma isi.

vaila'au e gaosia ai pepa (e pei o le antifoam agent, fa'apipi'i fesoasoani)

sui antifoam: faʻaaogaina i le pulupulu, faʻapipiʻi pepa, faʻapipiʻi ma isi faiga o le defoaming, o ituaiga autu o lima koale poʻo kerosene emulsified, fatty acid esters, low carbon alcohols, silicones, amides ma isi.

fa'apipi'i ausilali: lubricants, e pei o le calcium stearate dispersion; fa'asao, pei ole isothiazolinone, p-chloro-m-toluene; fa'asalalauga fa'asalalau, e pei o le sodium hexametaphosphate, sodium polyacrylate; viscosity modifiers, e pei o le CMC, alkali soluble uplift o sodium polyacrylate ma isi.

O le faʻamoemoe o le faʻaleleia lea o le tulaga lelei o pepa ma le gaosiga lelei, faʻaleleia tulaga faʻaogaina, faʻaitiitia tau o gaosiga, faʻateleina penefiti tau tamaoaiga ma atinaʻe ituaiga pepa fou.
