Selulosi ya sodium carboxymethyl (CMC) yo gusiga impapuro

Selulose ya sodium carboxymethyl (CMC)ni polymeri ishongesha amazi ya anionic iboneka binyuze mu guhindura imiti ishingiye kuri selulose karemano. Ifite ubushobozi bwo gushonga neza mu mazi, ubushobozi bwo gukora filime, gufatana, gukomera no kudahagarara, kandi ikoreshwa cyane mu nganda nyinshi zikora impapuro, cyane cyane mu gutunganya impapuro.

1. Ibisabwa by'ibanze mu gusiga impapuro

Intego nyamukuru yo gusiga impapuro ni ukunoza imiterere y’ubuso bw’impapuro, harimo uburyo bworoshye, ubw’urumuri, kudahinduka, kwinjizwa kwa wino, kwihuta mu gucapa, nibindi. Uburyo busanzwe bwo gusiga impapuro bugizwe n’ibisigazwa (nka kaolini, karubone kalisiyumu, talki, nibindi), ibifunga (nka emulsions, starch, CMC, nibindi) n’ibindi biyongera (nk’ibisigazwa, amavuta, ibikoresho bikingira amazi, nibindi). Mu gihe cyo gusiga impapuro, guhagarara no guhindagurika kw’ibisigazwa n’imiterere y’ibisigazwa nyuma yo kuma bigira uruhare runini mu bwiza bw’impapuro.

2. Uruhare rwa CMC mu gusiga impapuro

2.1. Imikorere ya Binder

CMC ishobora gukoreshwa nk'icyuma cy'inyongera ku mabara, kandi igakorana n'icyuma gikuru (nk'imyumure, sitashi) kugira ngo inoze uburyo amabara afatanye ku buso bw'impapuro, bityo yongere imbaraga zo gusiga no kudakura.

2.2. Umugenzuzi w'ubucucike n'ubw'imitsi

CMC ishobora gukora umuti wa colloidal ufite ubukana runaka mu mazi, ushobora guhindura neza imiterere ya rheological y'igitambaro, kunoza uburinganire n'ubudahangarwa bw'igitambaro mu gihe cyo gusiga, no gufasha kubona ubugari bumwe bw'igitambaro.

2.3. Ituma ibintu bitagenda neza

Kongeramo ingano ikwiye ya CMC muri formula yo gusiga bishobora kunoza uburyo uduce tw’ibara ry’umutuku dukwirakwira, bikabuza ko ibara ry’umutuku rihinduka no guhindagurika, kandi bigatuma ibara ry’umutuku riguma mu buryo buhamye mu gihe cyo kubika no gukoresha.

2.4. Kunoza imikorere y'ipamba

CMC ifite ubworoherane bwiza n'uburyo firime ingana nyuma yo gukora firime, ibi bishobora kunoza cyane ubuso butoshye, uburyo bworoshye bwo gucapa no guhindura isura, cyane cyane ikwiriye impapuro zipfutse, ikarito yera ipfutse, impapuro zo gucapa zo mu rwego rwo hejuru, nibindi.

2.5. Kubika amazi no kuyasiga neza

CMC ishobora kunoza ubushobozi bwo kubika amazi mu gipfundikizo, ikabuza amazi guhindagurika vuba mu gipfundikizo munsi y’aho gipfundikirizwa cyangwa ahantu humutse, kandi ikagenzura ko igipfundikizo gikozwe kimwe; icyarimwe, ubushyuhe bwayo bufasha kugabanya ubushyuhe bw’imashini no kunoza imikorere myiza y’umusaruro.

3. Ibiranga imikoreshereze ya CMC

3.1. Gushonga neza cyane mu mazi

CMC yoroshye gushonga mu mazi akonje, yoroshye kuyikoresha, kandi ishobora gutegurwa neza ku bushyuhe bw'icyumba idashyushye.

3.2. Ubwoko bw'ubukonje bukungahaye ku bushyuhe

CMC ifite ubunini butandukanye bw'ubushyuhe ikwiriye ubwoko butandukanye bw'impapuro zipfutse n'ibisabwa mu gutunganya. Abakoresha bashobora guhitamo icyitegererezo gikwiye bitewe n'ibyo bakeneye by'ukuri.

3.3. Gukomera neza mu binyabutabire

CMC yihanganira cyane ubushyuhe, urumuri, aside na alkali, kandi ntibyoroshye kwangirika no kwangirika nyuma yo gukoreshwa igihe kirekire.

3.4. Irinda ibidukikije kandi ntigira uburozi

Kubera ko CMC ari ikintu gikomoka kuri selulosi gikomoka ku bintu karemano, ntabwo ari uburozi kandi nta cyo butwaye, ibi bikaba bihuye n’icyerekezo cy’iterambere ry’uburinzi bw’ibidukikije mu nganda zikora impapuro.

4. Ingingo z'ingenzi z'uburyo bwo gusaba

Mu ikoreshwa nyaryo, kugira ngo CMC igire uruhare rwiza mu buryo bwo gusiga irangi, ingingo zikurikira zigomba kwitabwaho:

4.1. Uburyo bukwiye bwo gusenya

Mbere yo gukoresha CMC, igomba gushyirwamo buhoro buhoro mu mazi akonje yihuta kugira ngo hirindwe ko iterana cyangwa koroha cyane. Ni byiza kuyishyiramo mu byiciro no gukomeza kuyivanga kugeza ishongeshejwe burundu.

4.2. Kugenzura neza igipimo

Muri rusange, ingano ya CMC yongeweho ni hagati ya 0.1% na 0.5% by'uburemere bw'ipamba ryumye. Ingano ihindurwa hakurikijwe ibisabwa mu mikorere y'ipamba n'uburyo bwo gusiga. Kongeramo byinshi bishobora gutuma ubushyuhe bw'ipamba buba bwinshi cyane, bigagira ingaruka ku mikorere y'ipamba.

4.3. Ihuza neza n'ibindi bikoresho by'inyongera

CMC ijyanye n'ibindi bikoresho bitandukanye byo gusiga (nk'imiti igabanya ubushyuhe, imiti igabanya ubushyuhe, imiti irinda ubushyuhe, nibindi), ariko hakwiye kwitabwaho uburyo ihuye n'ibindi bikoresho bikomeye byo gusiga kugira ngo hirindwe ko amazi yagwa cyangwa ngo habeho imvura.

5. Ingero z'ikoreshwa rya CMC mu mpapuro zitandukanye

Impapuro zipfutse: zikoreshwa mu kunoza uburyo irangi ritoshye n'ubushyuhe, mu gihe zongerera ubushobozi irangi rifatana;

Ikarito y'umweru: kunoza ubushobozi bwo gupfunyika no guhindura uburyo bwo gucapa;

Impapuro zigaragaza ibirango n'impapuro zishyushya: kunoza imiterere y'igitambaro cyo hejuru no gucapa neza;

Icapa rinini ripfutse: rituma amazi apfutse adahindagurika kandi rigabanye uburyo wino ikoreshwa mu gucapa yinjira.

Nk'ikintu gisanzwe cya polymer gifite imikorere myiza, sodium carboxymethyl cellulose igira imirimo myinshi mu gusiga impapuro, nko gufatanya, kuzikuba, kuzitatanya no kunoza imiterere y'ubuso. Ihendutse, ituze ryiza no kurengera ibidukikije bituma igira umwanya ukomeye mu nganda zigezweho zo gukora impapuro. Hamwe no kunoza ubwiza bw'impapuro no guteza imbere ibitekerezo byo gukora impapuro z'icyatsi kibisi,CMC izakomeza kugira uruhare runini mu bijyanye no gusiga impapuro.
