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:

pulupulu vaila'au (e pei o fesoasoani kuka, vailaau fa'ainu, ma isi.)

1. Fesoasoani kuka: faʻaaogaina e faʻavavevave ai le saoasaoa ma le gaosiga o kuka pulupulu vailaʻau, e masani ona faʻaaogaina e masani ona i ai le anthraquinone ma le quinone derivatives, surfactants ma isi.
2. Deinking agent: E faʻaaogaina mo le deinking i le faagasologa o le toe faʻaaogaina o pepa otaota ma 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 opulupulusui fa'atau,su'ega fa'ameamea, ma isi.):

1. Pulp sizing agent: sizing agent faaopoopo i le pulp, ina ia 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 reactive synthetic sizing agent, petroleum resin sizing agent ma isi.
2. Laupapa sizing agent: faʻaaogaina mo le faʻapipiʻiina o luga o le pepa e faʻaleleia ai le malosi o le pepa, faʻaitiitia le paʻu, lint ma isi mea faʻapitoa, faʻapitoa faʻafefeteina, e pei o le oxidized starch, 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 oantifoam agent, ufiufiausilali)

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