Ubwoko nogukoresha imiti yimpapuro

Imiti yimpapuro yerekana imiti itandukanye ikoreshwa mugukora impapuro, ijambo rusange ryabafasha.Harimo ibintu byinshi birimo:

gufata imiti (nk'imfashanyigisho zo guteka, ibikoresho byo kumena, n'ibindi.)

Imfashanyo zo guteka: zikoreshwa mukwihutisha umuvuduko numusaruro woguteka imiti, gutondeka mubisanzwe bifite anthraquinone nibikomoka kuri cinone, surfactants nibindi.

Deinking agent: Ikoreshwa mugucengera mugikorwa cyo gutunganya impapuro zangiza no kongera gutobora, zishobora kunoza umweru wa pulp no gukuraho umwanda utandukanye nkududomo twa wino, nibindi. detergent, na anti-reprecipitant.

imiti yimpapuro (nka pulp sizing agent, agent sizing agent, nibindi.):

Pulp sizing agent: agent ingana yongewe kuri pulp, kugirango igire uruhare runini, muri rusange amase ya rosin saponification, amavuta ya rosin yongerewe imbaraga, amavuta ya rosin (anionic yatatanye rosin gum, cationic yatatanye rosin gum), AKD na ASA nibindi bikora. sintetike idafite aho ibogamiye, peteroli resin ingana nibindi.

Ubunini buringaniye: bukoreshwa mubunini bwimpapuro kugirango hongerwe imbaraga hejuru yimpapuro, kugabanya ifu, linti nibindi bintu, cyane cyane byahinduwe na krahisi, nka okiside ya okiside, acetate ya acarike, ibinyamisogwe bihujwe;selile yahinduwe, nka carboxymethyl selile;polymers ya sintetike, nka alcool ya polyvinyl, polyacrylates, styrene maleic anhydride copolymers, ibishashara nibindi;polymer karemano, nka chitosan, gelatine nibindi.

imiti itunganya impapuro (nka antifoam agent, abafasha ba coating)

antifoam agent: ikoreshwa mugukubita, gukora impapuro, gutwikira hamwe nubundi buryo bwo gusebanya, ubwoko bwingenzi bwikara ryamakara cyangwa emulisile ya kerosene, ester acide fatty, alcool nkeya ya karubone, silikoni, amide nibindi.

abafasha ba coating: amavuta, nka calcium stearate ikwirakwiza;imiti igabanya ubukana, nka isothiazolinone, p-chloro-m-toluene;gukwirakwiza ibikoresho, nka sodium hexametaphosphate, sodium polyacrylate;abahindura viscosity, nka CMC, alkali soluble kuzamura ya sodium polyacrylate nibindi.

Ikigamijwe ni ukuzamura ireme ryimpapuro no gukora neza, kunoza imikorere, kugabanya ibiciro byinganda, kongera inyungu zubukungu no guteza imbere ubwoko bushya bwimpapuro.
