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 imyanda yongeye gutunganywa no kongera guterura, bishobora kuzamura umweru wa pulp no kuvanaho umwanda utandukanye nkutudomo twa wino, nibindi.

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

Pulp sizing agent: sizing agent yongewe kuri pulp, kugirango igire uruhare runini, muri rusange rosin saponification gum, gumine ya rosin ishimangirwa, ikariso ya rosin (amavuta ya anionic ikwirakwiza rosin gum, cationic ikwirakwiza rosin gum), AKD na ASA hamwe nubundi buryo bwa sintetike itagira aho ibogamiye.

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.
