CMC (carboxymethyl selulose) munganda zikora impapuro ninyongera yingenzi ikoreshwa mugutezimbere ubwiza nimikorere yimpapuro. CMC ni amazi ya elegitoronike ya polymer yuzuye hamwe nuburyo bwiza bwo guhindura imiterere kandi bigira uruhare runini mugukora impapuro.
1. Ibintu shingiro bya CMC
CMC ikomoka kuri selile, ikorwa mugukora hydroxyl igice cya selile hamwe na acide chloroacetic. Ifite amazi meza yo gukemura hamwe nubushobozi bwo guhindura viscosity. CMC ikora igisubizo kiboneye nyuma yo gushonga mumazi, bigatuma igira akamaro cyane mubikorwa bitandukanye byinganda.
2. Uruhare rwa CMC mu nganda zikora impapuro
Mubikorwa byo gukora impapuro, CMC ikoreshwa cyane cyane ifata, ikabyimbye kandi ikomeza. Mu bikorwa byayo harimo:
2.1 Kunoza imbaraga zimpapuro
CMC irashobora kongera imbaraga hamwe no guhagarika impapuro, kandi igateza imbere amarira no guhangana nimpapuro. Uburyo bwibikorwa ni ugukora impapuro zikomeye kandi ziramba mukuzamura imbaraga zihuza fibre.
2.2 Kunoza ububengerane nubuso bwimpapuro
Ongeraho CMC irashobora kuzamura ubwiza bwimpapuro kandi bigatuma impapuro zoroha. Irashobora kuzuza neza icyuho kiri hejuru yimpapuro kandi ikagabanya ubukana bwubuso bwimpapuro, bityo bikazamura ububengerane no gucapa guhuza impapuro.
2.3 Igenzura ububobere bwa pulp
Mugihe cyo gukora impapuro, CMC irashobora kugenzura neza ububobere bwimbuto kandi ikanemeza neza kandi neza. Ubukonje bukwiye bufasha gukwirakwiza neza, kugabanya inenge, no kunoza umusaruro.
2.4 Kunoza uburyo bwo gufata amazi ya pulp
CMC ifite ubushobozi bwiza bwo gufata amazi kandi irashobora kugabanya gutakaza amazi ya pulp mugihe cyo kubumba. Ibi birashobora kugabanya kugabanuka kwimpapuro nibibazo byo guhindura ibintu bibaho mugihe cyo kumisha, bityo bikazamura umutekano wimpapuro.
3. Guhindura ubwiza bwa CMC
Ubukonje bwa CMC ni ikintu cyingenzi kigira ingaruka mubikorwa byo gukora impapuro. Ukurikije umusaruro ukenewe, umusaruro wa CMC urashobora guhinduka muguhindura ubunini bwacyo hamwe nuburemere bwa molekile. By'umwihariko:
3.1 Ingaruka yuburemere bwa molekile
Uburemere bwa molekuline ya CMC bugira ingaruka itaziguye kubwiza bwayo. CMC ifite uburemere bunini bwa molekuline mubusanzwe ifite ubukonje bwinshi, bityo uburemere buke bwa molekile CMC ikoreshwa mubisabwa bisaba ubwiza bwinshi. Uburemere buke bwa CMC burakwiriye mubihe bisaba ubukonje buke.
3.2 Ingaruka zo gukemura ibibazo
Ubwinshi bwibisubizo bya CMC nabwo ni ikintu cyingenzi kigira ingaruka ku bwiza. Muri rusange, uko ibisubizo bya CMC bigenda byiyongera, niko ubwiza bwabyo. Kubwibyo, mubikorwa nyabyo, igisubizo cyibisubizo bya CMC bigomba guhindurwa ukurikije ibisabwa byihariye kugirango ugere kurwego rukenewe.
4. Kwirinda gukoresha CMC
Iyo ukoresheje CMC mugikorwa cyo gukora impapuro, ingingo zikurikira zigomba kwitonderwa:
4.1 Ikigereranyo nyacyo
Umubare wa CMC wongeyeho ugomba guhinduka ukurikije ibisabwa byimpapuro. Niba hiyongereyeho byinshi, birashobora gutuma impanuka ya visp iba hejuru cyane kandi ikagira ingaruka kubikorwa; niba bidahagije, ingaruka ziteganijwe ntizishobora kugerwaho.
4.2 Igenzura ryimikorere
CMC igomba gushonga mumazi akonje kugirango birinde kwangirika mugihe cyo gushyuha. Igikorwa cyo gusesa kigomba gukangurwa byimazeyo kugirango CMC iseswe burundu kandi birinde agglomeration.
4.3 Ingaruka zagaciro ka pH
Imikorere ya CMC izagerwaho nigiciro cya pH. Mu gukora impapuro, urwego pH rukwiye rugomba kubungabungwa kugirango habeho ingaruka nziza za CMC.
CMC igira uruhare runini mu nganda zikora impapuro, kandi ubushobozi bwayo bwo guhindura ububobere bugira ingaruka ku miterere n’imikorere yimpapuro. Muguhitamo neza no gukoresha CMC, imbaraga, gloss, koroshya no gukora neza impapuro zirashobora kunozwa cyane. Ariko, mubikorwa nyabyo, kwibanda hamwe nubwiza bwa CMC bigomba guhinduka neza ukurikije ibisabwa byumusaruro kugirango habeho ingaruka nziza.
