Isesengura rya Carboxymethyl Cellulose (CMC)

Carboxymethyl Cellulose (CMC) ni amazi akoreshwa mu mazi menshi mu buryo butaziguye, abyibushye ndetse n'umutekano wa Colloidal. Iboneka mugusimbuza amatsinda ya hydroxyl kuri molekile ya molekile hamwe nitsinda rya carboxymethyls (-ch2cooh). Iyi miti ihindura molekile ya CMC ifite hydropile ikomeye kandi itatagabanijwe, cyane cyane mubisubizo byingenzi byo guhinduranya uruhara, bityo bikakoreshwa mubushobozi bwihariye bwo guhinduranya urukwavu, bityo bikakoreshwa cyane mubushobozi bwa vinosiya, niko bikoreshwa cyane mubushobozi bwa vino, bityo birakoreshwa cyane mubushobozi bwanduye, bityo bikoreshwa cyane mubushobozi bwikibazo, ibiryo, ubuvuzi, kwisiga hamwe nizindi nzego.

1. ibisobanuro n'inkunga y'ibintu bya CMC bidashoboka
Ibitagenda neza bya CMC mubisanzwe bivuga ubushobozi bwo gutatana no gushonga mumazi cyangwa ibindi bicuruzwa. Cellulose ubwayo ihujwe mumazi, ariko nyuma yo guhindura, CMC ifite amazi meza. Gutata Imana bigira ingaruka kubintu byinshi, cyane cyane harimo ibintu bikurikira:

Uburemere bwa molekilar: Uburemere bwa moleki ya CMC bugira ingaruka kuburyo butaziguye kandi butabishaka. Uburemere bwo hejuru mubisanzwe bisobanura imiterere nini ya molekelar, zishobora gutera iseswa gahoro gahoro kandi rishobora kugira ingaruka kuri viscosiya igisubizo cyanyuma, bityo bigira ingaruka kubitekerezo byo gutatanya. CMC hamwe nuburemere bwa molecular bufite imbaraga butange neza mubisubizo, ariko ingaruka zacyo zirasa intege.

Urwego rwa Carboxymethylation: kudahatanya CMC bifitanye isano rya bugufi nurwego rwarwo rwo guhindura imiti. Urwego rwo hejuru rwa CarboxyMethtion rusobanura amatsinda menshi ya hydrophilic (-cooh) muri molekile, ashobora gukora imikoranire iri hagati ya molekile, bityo yongerera imikoranire hagati ya molekile, bityo ikangisha CMC. Ibinyuranye, urwego rwo hasi rwa Carboxymethylation rushobora gutuma ibibi bidafite ishingiro rya CMC, cyangwa nubwo bigoye gushonga.

PH agaciro k'igisubizo: Kudashoboka no kudatekereza CMC birashobora gutandukana cyane ku ndangagaciro zitandukanye. Muri aside cyangwa kutabogama, CMC muri rusange idahatirwa; Mugihe hateganijwe ibihe bya alkaline, hydrophileilique ya CMC yongerewe imbaraga, zishobora kongera ubuswa bwigisubizo cya CMC kandi bigira ingaruka kumitabi. Kubwibyo, guhinduka kwa PH ni ngombwa kugirango CMC idahwitse.

Imbaraga za Ionic: Ion Mentration mubisubizo nayo izagira ingaruka kumiti idahwitse ya CMC. Ibitekerezo byinshi byumunyu cyangwa ibindi bintu bya ionize byishobora kugabanya ibibazo byayo no kudahatanya mugusabana nibirego bibi muri molekile ya CMC. CMC yerekana ingaruka nziza zo gutatanya munsi yububasha buke bwa ionic imbaraga.

Ubushyuhe: Ubushyuhe nabwo bufite ingaruka runaka kumagambo ya CMC. Mubisanzwe, ubwiyongere bwubushyuhe buzahita bwihutisha gahunda yo gusebanya CMC no kunoza ibitabi. Ariko, ubushyuhe bwinshi bushobora gutera gutandukana cyangwa guteranya urunigi rwa CMC, nabyo bigira ingaruka ku nyungu zayo no gutanga ingaruka. Kubwibyo, kugenzura ibintu byumvikana ni ngombwa kugirango CMC idahwitse.

2. Gusaba imirima ya CMC idahwitse
Ibitagenda neza bya CMC bituma bikoreshwa cyane mumirima myinshi. Ibikurikira ni bimwe mubice byingenzi byasabye:

Gukora no gushushanya: Muburyo bwo kwitegura kwikuramo no gushushanya, CMC, nkuwabyimbye kandi ukwirakwiza, urashobora gutatanya pigment nibindi bice bikomeye kandi bibabuza gutura. Kubera hydrofilique yayo ikomeye, CMC irashobora gutondeka itatatana mubitabo bishingiye ku mazi, bityo bigatuma umutekano no guhuriza hamwe.

Inganda zibiribwa: CMC, nkuwabyimbye nintangiriro, ikoreshwa cyane munganda zibiribwa, nka jelly, ice cream, bombo n'umugati. Mu biryo, CMC ifasha kunoza imiterere nuburyohe bwibicuruzwa, mugihe ukomeza kuvanga ibikoresho fatizo mugutezimbere bidashoboka.

Imyiteguro ya farumasi: Mu nganda za farumasi, CMC ikoreshwa nk'agateganyo kandi ikinganya mu gutegura ibiyobyabwenge, imiti, ibitonyanga by'amaso, ibitonyanga by'amaso, guhagarikwa no mu bindi byitegura. Ibyiza byayo bidashoboka bifasha kwemeza kimwe cyo gukwirakwiza ibiyobyabwenge no kunoza umutekano wibiyobyabwenge.

Inganda zo kwisiga: CMC ikoreshwa cyane mumavuta yo kwisiga, cyane cyane mubicuruzwa nkibibazo, amavuta, shampoos na pasika. Ntabwo bidashoboka birashobora kwemeza ko ikwirakwizwa ryibikoresho no kunoza umutekano no gukoresha uburambe bwibicuruzwa.

Impapuro n'imyenda: CMC ikunze gukoreshwa muburyo bwo gukora impapuro nimyenda nkimyenda nkiyasimbana kugirango iteze imbere imbaraga nubwiza bwimpapuro. Mu icapiro no gusiga irangi ry'imyenda, CMC irashobora gutatanya dyes na pigment kugirango habeho ingaruka imwe.

3. Ingamba zo kumenya CMC idahwitse
Kugirango ugere kunoza CMC idahwitse, ingamba zikurikira zishobora kwemezwa:

Hindura uburemere bwa molekilar na carboxymethylation ya CMC: Mu kugenzura ibiro bya molekile na carboxymethylation ya CMC, idahakana muburyo butandukanye burashobora guhinduka. Kurugero, uburemere bwo hejuru bwa molekiland nurwego rwo hejuru rwa Carboxymethylation irashobora gufasha kunonosora CMC mubisubizo byatangajwe.

Gukoresha surfactints: Mubyiciro bimwe, byongeramo umubare ukwiye wa CMC birashobora kunoza ibintu bidahabijwe na CMC, cyane cyane iyo bihuye namavuta-amazi adasobanutse. Kwirukanwa birashobora kugabanya impagarara zifatanije no guteza imbere gutatanya molekile ya CMC.

Kunoza ibidukikije: Igenzura ryuzuye ryubushyuhe bwa CMC, PH agaciro ka PH hamwe nibitekerezo bya Solvent birashobora kunoza bidashoboka. Kurugero, CMC muri rusange imeze neza mubushyuhe buke kandi butabogamye PH.

Kwiyongera hamwe nabandi bapatanya: Mubyiciro byihariye, CMC irashobora kwiyongera hamwe nabandi bapatanya kugirango bagere kubintu bitabi. Kurugero, hashobora kubaho ibiro byinshi byo hejuru ya polymers cyangwa ibicuruzwa kamere birashobora gukorana na CMC kugirango zongere ibintu bitatabi.

Carboxymethyl selile ifite agaciro gatagira ingano kandi ikoreshwa cyane mu matara, ibiryo, imiti, kwisiga, kwisiga n'izindi nganda. Ibitabi byayo bigira ingaruka kubintu byinshi nkuburemere bwa molecular, urwego rwa carboxymethylation, PH agaciro ka PH agaciro, imbaraga za ionic nubushyuhe. Gutata Imana birashobora gukomeza guhindurwa binyuze muburyo bukwiye bwo guhitamo, nko guhindura uburemere bwa molekile no gukoresha ibirurwa. Nkibisabwa inganda zikomeje kwiyongera, ubushakashatsi bwa CMC buzengurutse bwa CMC buzakomeza kurushaho kubahiriza ibyo dutandukanye nibikenewe bitandukanye.
