Mefuta le Tšebeliso ea lik'hemik'hale tsa pampiri

Lik'hemik'hale tsa pampiri li bua ka mefuta e fapaneng ea lik'hemik'hale tse sebelisoang ha ho etsoa pampiri, lentsoe le akaretsang la li-axiliary.Ho kenyeletsoa mefuta e mengata ea litaba:

lik'hemik'hale tsa pulping (tse kang lithuso tsa ho pheha, li-deinking agents, joalo-joalo)

Lisebelisoa tsa ho pheha: tse sebelisetsoang ho potlakisa lebelo le tlhahiso ea ho pheha lik'hemik'hale, tse sebelisoang hangata li na le li-anthraquinone le quinone derivatives, surfactants joalo-joalo.

Deinking agent: E sebelisoa bakeng sa ho nyenyefatsa ts'ebetsong ea ho sebelisa pampiri ea litšila le ho phunya hape, e ka ntlafatsang bosoeu ba makhasi le ho tlosa litšila tse fapaneng joalo ka matheba a enke, joalo-joalo. sesepa, le anti-reprecipitant.

lik'hemik'hale tsa pampiri (joalo ka li-ajenti tsa ho leka-lekanya makhasi, lisebelisoa tsa boholo ba bokaholimo, joalo-joalo):

Sesebelisoa sa boholo ba pulp: sesebelisoa sa sizeng se kenyellelitsoeng pulp, molemong oa ho bapala karolo ea boholo, hangata rosin saponification gum, reinforced rosin gum, rosin gum (anionic dispersed rosin gum, cationic disspersed rosin gum), AKD le ASA le tse ling tse sebetsang hantle. synthetic neutral sizing agent, petroleum resin sizeing agent joalo-joalo.

Setsi sa boholo ba sefahleho: se sebelisetsoa ho etsa boholo ba pampiri ho ntlafatsa matla a pampiri, ho fokotsa phofo, lesela le lintho tse ling, haholo-holo starch e fetotsoeng, joalo ka starch e nang le oxidized, starch acetate, crosslinked starch;selulose e fetotsoeng, joalo ka carboxymethyl cellulose;li-polymers tsa maiketsetso, tse kang joala ba polyvinyl, polyacrylates, styrene maleic anhydride copolymers, li-emulsion tsa boka, joalo-joalo;polymer ea tlhaho, joalo ka chitosan, gelatin joalo-joalo.

lik'hemik'hale tse sebetsanang le pampiri (joalo ka moemeli oa antifoam, lisebelisoa tsa ho roala)

antifoam agent: e sebelisoang ho pulping, papermaking, ho roala le mekhoa e meng ea ho senya, mefuta e ka sehloohong ea letsoho la mashala kapa parafine e entsoeng ka emulsified, mafura a acid ester, carbon alcohols e tlaase, silicones, amides joalo-joalo.

lithuso tsa ho roala: litlolo, joalo ka ho hasana ha calcium stearate;li-preservatives, tse kang isothiazolinone, p-chloro-m-toluene;lisebelisoa tse qhalakang, tse kang sodium hexametaphosphate, sodium polyacrylate;viscosity modifiers, joalo ka CMC, alkali soluble uplift ea sodium polyacrylate joalo-joalo.

Sepheo ke ho ntlafatsa boleng ba pampiri le tlhahiso e sebetsang hantle, ho ntlafatsa maemo a ts'ebetso, ho fokotsa litšenyehelo tsa tlhahiso, ho eketsa melemo ea moruo le ho hlahisa mefuta e mecha ea pampiri.
