Urwego rwo gukora impapuro CMC

Icyiciro cyo gukora impapuro CMC Sodium carboxymethyl selulose ifite gufatana neza, kubyimba, emulioni, guhagarikwa, flocculation, firime, kurinda colloid, kugumana amazi, gutuza imiti nibintu byiza nka pulp fibre ifitanye isano, kwinjiza amatsinda ya hydrophilique carboxymethyl mumiterere yayo ya molekile, kora kubyimba kwa selile yiyongereye cyane, byoroshye guhumeka fibre no kuzuza ibice byuzuzanya, byongera ubukana nimbaraga zimpapuro; Irashobora kuzamura impyisi hamwe nuwuzuza hamwe nuburyo bubi kandi butandukanye, kugirango fibre hamwe nuwuzuza bikwiranye neza muri pulp, bitezimbere impapuro; Urwego rwo gukora impapuro CMC Irashobora gukoreshwa murwego rwo hejuru rwo hejuru kugirango utezimbere imbaraga kandi byoroshye impapuro; Irashobora gukwirakwiza pigment neza no kunoza ingaruka zo gucapa no gusiga irangi. Irashobora kunoza ingaruka zo gufata amazi mugucunga no guhindura rheologiya yo gutwikira. Irashobora kwerekana umweru mwiza hamwe niterambere ryiza kuruta ibinyamisogwe, polyethylene glycol nizindi zitwara fluorescent itwara ibintu, ni umufasha wimpapuro nyinshi.

 

Muruhare rwa CMC mu nganda zimpapuro:

1. Irangi

Kugenzura no guhindura imvugo yo gusiga irangi no gukwirakwiza pigment, kunoza ibintu bikomeye by'irangi;

Kora igifuniko gifite plastiki yibinyoma, kunoza umuvuduko;

Gutezimbere kubika amazi, kurinda amazi yimuka yimuka;

Ifite firime nziza, itezimbere ububengerane bwa coating;

Kunoza igipimo cyo kugumana umukozi wera mugutwikira, kunoza umweru wimpapuro;

Kunoza imikorere yo gusiga amavuta, kuzamura ubwiza bwikibiriti, kuramba kumurimo wa scraper.

2. Ongeraho muburyo bworoshye

Kunoza gusya neza, guteza imbere gutunganya fibre, kugabanya igihe cyo gukubita;

Hindura ubushobozi bwamashanyarazi imbere muri pulp, ukwirakwize fibre, utezimbere "gukoporora imikorere" yimashini yimpapuro, kandi urusheho kunoza imiterere yurupapuro;

Kunoza kugumana inyongeramusaruro zitandukanye, kuzuza na fibre nziza;

Ongera imbaraga zihuza fibre, utezimbere imiterere yimpapuro;

Imbaraga zumye kandi zitose zimpapuro zirashobora kunozwa mugihe zikoreshejwe hamwe nimbaraga zumye kandi zitose.

Kurinda rosin, AKD nibindi bikoresho bingana, byongera ingaruka zingana.

3. Ingano y'ubuso

Ifite imitungo myiza ya rheologiya na firime ikora umutungo.

Mugabanye imyenge yubuso, kunoza amavuta yimpapuro;

Ongera urumuri nuburabyo bwimpapuro;

Ongera impapuro zikomeye, zorohewe, kugenzura ibicuruzwa;

Ongera imbaraga zo hejuru kandi wambare impapuro, kugabanya imisatsi nifu, kunoza ubwiza bwo gucapa.

Gusaba

Mu nganda zimpapuro, CMC ikoreshwa mugikorwa cya pulping, gishobora kuzamura igipimo cyo kugumana no kongera imbaraga zitose. Ikoreshwa mubunini bwubuso, nkibintu byoroshye, kunoza imiterere yimbere, kugabanya ivumbi ryicapiro, kunoza ubwiza bwo gucapa; Ikoreshwa mu gutwikira impapuro, ifasha gutatanya no gutembera kwa pigment, kuzamura impapuro neza, koroshya, imiterere ya optique no guhuza imiterere. Mu nganda zimpapuro nkigiciro gifatika hamwe ninyongeramusaruro zinyuranye, cyane cyane kubera firime ya elegitoronike ya polymer ikora kandi ikarwanya amavuta.

● Ikoreshwa mugupima impapuro, kugirango impapuro zigire ubucucike bwinshi, irwanya neza wino nziza, gukusanya ibishashara byinshi kandi byoroshye.

● Irashobora kunoza impapuro imbere fibre yimbere yimbere, kugirango uzamure imbaraga zimpapuro hamwe no guhangana.

● Mu mpapuro no gutunganya impapuro, CMC ifasha kugenzura imigendekere yamabara ya paste hamwe no kwinjiza neza wino.

Mubisanzwe, dosiye isabwa ni 0.3-1.5%.

 

Gupakira:

Igicuruzwa cya CMC gipakiye mumifuka itatu yimpapuro hamwe numufuka wa polyethylene wimbere ushimangirwa, uburemere bwa net ni 25kg kumufuka.
