Ibintu bigira ingaruka kumashanyarazi ya hydroxyethyl selulose

1. Imiterere ya molekile

Imiterere ya molekuline ya sodium carboxymethyl selulose (CMC) igira uruhare rukomeye mukuboneka kwayo mumazi. CMC ikomoka kuri selile, kandi imiterere yayo ni uko amatsinda ya hydroxyl kumurongo wa selile asimburwa igice cyangwa asimbuwe rwose nitsinda rya carboxymethyl. Urwego rwo gusimbuza (DS) ni ikintu cy'ingenzi, cyerekana impuzandengo y'amatsinda ya hydroxyl yasimbujwe na carboxymethyl matsinda kuri buri glucose. Urwego rwo hejuru rwo gusimbuza, hydrophilicity ya CMC irakomera, kandi niko gukomera. Nyamara, urwego rwo hejuru cyane rwo gusimburwa rushobora no gutuma habaho imikoranire myiza hagati ya molekile, nayo igabanya ubukana. Kubwibyo, urwego rwo gusimburwa ruringaniza no gukemuka murwego runaka.

2. Uburemere bwa molekile

Uburemere bwa molekuline ya CMC bugira ingaruka kubishobora. Mubisanzwe, uburemere buke bwa molekile, niko gukomera. Uburemere buke bwa molekuline CMC ifite urunigi rurerure kandi rugoye, biganisha ku kwiyongera no gukorana mubisubizo, bikagabanya gukemura. Uburemere buke bwa molekile CMC birashoboka cyane gukora imikoranire myiza na molekile zamazi, bityo bikazamura imbaraga.

3. Ubushyuhe

Ubushyuhe ni ikintu cyingenzi kigira ingaruka kuri CMC. Mubisanzwe, kwiyongera kwubushyuhe byongera imbaraga za CMC. Ni ukubera ko ubushyuhe bwinshi bwongera ingufu za kinetic ya molekile zamazi, bityo bikangiza imigozi ya hydrogène nimbaraga za van der Waals hagati ya molekile ya CMC, bikoroha gushonga mumazi. Nyamara, hejuru cyane ubushyuhe bushobora gutera CMC kubora cyangwa gutandukana, bidafasha guseswa.

4. Agaciro pH

Ubushobozi bwa CMC nabwo bufite uruhare runini kuri pH yumuti. Mubidukikije bidafite aho bibogamiye cyangwa alkaline, amatsinda ya carboxyl muri molekile ya CMC azahinduka ioni muri COO⁻, bigatuma molekile ya CMC yishyurwa nabi, bityo bikazamura imikoranire na molekile zamazi no kunoza igisubizo. Ariko, mubihe bya acide cyane, ionisation yitsinda rya carboxyl irabujijwe kandi imbaraga zishobora kugabanuka. Byongeye kandi, imiterere ya pH ikabije irashobora gutera kwangirika kwa CMC, bityo bikagira ingaruka kubishobora.

5. Imbaraga za Ionic

Imbaraga za ionic mumazi zigira ingaruka kumashanyarazi ya CMC. Ibisubizo bifite imbaraga nyinshi za ionic birashobora gutuma habaho kutabogama kwamashanyarazi hagati ya molekile ya CMC, bikagabanya imbaraga zayo. Ingaruka yumunyu ni ibintu bisanzwe, aho ion nyinshi yibanda kugabanya ubukana bwa CMC mumazi. Imbaraga nke za ionic mubisanzwe zifasha CMC gushonga.

6. Gukomera kw'amazi

Gukomera kwamazi, kugenwa cyane nubunini bwa calcium na magnesium ion, nabyo bigira ingaruka kumashanyarazi ya CMC. Imyanya myinshi mumazi akomeye (nka Ca²⁺ na Mg²⁺) irashobora gukora ibiraro bya ionic hamwe nitsinda rya carboxyl muri molekile ya CMC, bikaviramo kwegeranya kwa molekile bikagabanuka. Ibinyuranye, amazi yoroshye afasha gusesa burundu CMC.

7. Imyivumbagatanyo

Imyivumbagatanyo ifasha CMC gushonga mumazi. Imyivumbagatanyo yongerera ubuso bwo guhuza amazi na CMC, bigateza imbere inzira yo gusesa. Imyivumbagatanyo ihagije irashobora kubuza CMC guteranya no kuyifasha gukwirakwiza mu mazi, bityo bikongerera imbaraga.

8. Kubika no gutunganya ibintu

Kubika no gutunganya ibintu bya CMC nabyo bigira ingaruka kumiterere yabyo. Ibintu nkubushuhe, ubushyuhe, nigihe cyo kubika birashobora kugira ingaruka kumiterere yumubiri na chimique ya CMC, bityo bikagira ingaruka kumashanyarazi. Kugirango ukomeze gukemuka neza kwa CMC, ugomba kwirinda kwirinda igihe kirekire guhura nubushyuhe bwinshi nubushyuhe bwinshi, kandi ibipfunyika bigomba kubikwa neza.

9. Ingaruka zinyongera

Ongeramo ibindi bintu, nkibikoresho byo gusesa cyangwa solubilisers, mugihe cyo gusesa kwa CMC birashobora guhindura imiterere yabyo. Kurugero, ibintu bimwe na bimwe bifata amazi cyangwa ibishishwa byamazi byamazi birashobora kongera imbaraga za CMC muguhindura uburemere bwibisubizo byumuti cyangwa polarite yikigereranyo. Byongeye kandi, ion zimwe cyangwa imiti yihariye irashobora gukorana na molekile ya CMC kugirango ibashe gukomera, bityo bitezimbere.

Ibintu bigira ingaruka zikomeye kuri sodium carboxymethyl selulose (CMC) mumazi harimo imiterere ya molekile, uburemere bwa molekile, ubushyuhe, agaciro ka pH, imbaraga za ionic, ubukana bwamazi, ibintu bitera imbaraga, kubika no gufata neza, hamwe ningaruka zinyongera. Izi ngingo zigomba gusuzumwa neza mubikorwa bifatika kugirango hongerwe imbaraga za CMC kandi zuzuze ibisabwa byihariye. Gusobanukirwa nibi bintu nibyingenzi mugukoresha no gukoresha CMC kandi bifasha kunoza ingaruka zikoreshwa mubice bitandukanye.
