Sodium carboxymethyl selulose

Sodium carboxymethyl selulose (CMC-Na) ni carboxymethylated ikomoka kuri selile kandi ni amase ya ionic selile. Sodium carboxymethyl selulose mubisanzwe ni anionic polymer compound yateguwe mugukora selile naturel na caustic alkali na acide monochloroacetic, ifite uburemere bwa molekile kuva kubihumbi n'ibihumbi. CMC-Na ni fibrous yera cyangwa ifu ya granulaire, impumuro nziza, uburyohe, hygroscopique, byoroshye gukwirakwiza mumazi kugirango bibe igisubizo kiboneye.

2. Imiterere yumubiri nubumara

CMC-Na kubintu bigufi, byera kugeza byijimye byifu yumuhondo, granular cyangwa fibrous ibintu, hygroscopicity ikomeye, byoroshye gushonga mumazi, kandi igisubizo ni amazi menshi ya viscosity iyo adafite aho abogamiye cyangwa alkaline. Ihamye kumiti, urumuri nubushyuhe. Nyamara, ubushyuhe bugarukira kuri 80 ° C, kandi iyo bishyushye igihe kirekire hejuru ya 80 ° C, ubukonje buzagabanuka kandi ntibuzashonga mumazi. Ubucucike bwacyo ni 1.60, naho ubwinshi bwa flake ni 1.59. Igipimo cyo kugabanya ni 1.515. Ihinduka umukara iyo ishyutswe kuri 190-205 ° C, na karubone iyo ishyushye kuri 235-248 ° C. Gukomera kwayo mumazi biterwa nurwego rwo gusimburwa. Kudashonga muri aside na alcool, nta mvura igwa mugihe umunyu. Ntibyoroshye gusembura, bifite imbaraga zikomeye zo gusohora amavuta n'ibishashara, kandi birashobora kubikwa igihe kirekire.

3. Porogaramu nyamukuru

Ikoreshwa cyane mu nganda zikomoka kuri peteroli gucukura ibyondo, ibikoresho byo mu bwoko bwa sintetike, ibyubaka umubiri, ibikoresho byo gucapa no gusiga irangi, imashini itanga amazi ya elegitoronike y’ibikoresho bya chimique ya buri munsi, tackifier na emulisiferi y’inganda zikora imiti, kubyimbye mu nganda z’ibiribwa Thickener, yometse kuri ceramic inganda, paste yinganda, ingero zinganda zinganda zimpapuro, nibindi bikoreshwa nka flocculant mugutunganya amazi, bikoreshwa cyane mugutunganya amazi mabi, bishobora kongera ibintu bikomeye bya cake.

Sodium carboxymethyl selulose nayo ni ubwoko bwibyimbye. Bitewe n'imikorere myiza yacyo, yakoreshejwe cyane mu nganda z’ibiribwa, kandi yanateje imbere iterambere ryihuse kandi ryiza ry’inganda z’ibiribwa ku rugero runaka. Kurugero, bitewe ningaruka zimwe na zimwe zo kubyimba no kwigana, irashobora gukoreshwa muguhagarika ibinyobwa bya yogurt no kongera ubwiza bwa sisitemu yogurt; kubera imiterere ya hydrophilicite hamwe na rehidrasiyo, irashobora gukoreshwa mugutezimbere ikoreshwa rya makaroni nkumugati numugati uhumeka. ubuziranenge, kongerera igihe cyibicuruzwa bya makaroni, no kunoza uburyohe; kubera ko ifite ingaruka nziza ya gel, ifasha muburyo bwiza bwo gukora gel mubiribwa, bityo irashobora gukoreshwa mugukora jelly na jam; irashobora kandi gukoreshwa nka firime yo kurya iribwa Ibikoresho byongewemo nibindi binini kandi bigashyirwa hejuru yibiribwa bimwe na bimwe, bishobora gutuma ibiryo bishya ku rugero runini, kandi kubera ko ari ibintu biribwa, ntabwo bizatera ingaruka mbi ingaruka ku buzima bwabantu. Kubwibyo, ibiryo-byo mu rwego rwa CMC-Na, nk'inyongeramusaruro nziza, bikoreshwa cyane mu musaruro w'ibiribwa mu nganda y'ibiribwa.
