Zvivakwa uye Zvikumbiro zveCarboxyMethyl Cellulose

1. Chikamu chepfupi cheCarboxymethyl Cellelose

Chirungu Zita: Carboxyl Methyl Cellulose

Chidimbu: CMC

Iyo molecular formula inoshanduka: [c6h7o2 (o) 2ch2coona] n

Chitarisiko: Ichena kana Chiedza chellow yellow granular gogo.

Solubility yemvura

Zvimiro: Yakakwira MOLECULAR YEMAHARA YEMADZIMAI ASALL ACLOID, YEMAHARA, YAKAKOSHESA UYE NEMAHARA.

Consulose Cellulose inoparadzirwa zvakanyanya mune zvakasikwa uye ndiyo yakanyanya kuwanda polysacchari. Asi mukugadzira, cellulose inowanzove mune fomu yeSodium Carboxymelm cellever, saka zita rizere rinofanira kunge riri sodium carboxymelose, kana cmc-na. Inoshandiswa zvakanyanya muindasitiri, kuvaka, mushonga, chikafu, machira, ceramics uye mamwe minda.

2. Carboxymethyl cellulose tekinoroji

Technology yekugadziridzwa yemasero inosanganisira: Kuwedzera uye Kuwedzera.

Shanduko yeCarboxyMethyl Cellemose: CarboxyMethylation Reaction Technology, Cellenose ndeye CarboxyMethylw

Mabasa eCarboxyMethyl CellOnce Solution mhinduro: Kuomesa, firimu kuumba, kusungwa, kudzivirirwa kwemvura, kudzivirirwa kwemvura, kudzivirirwa uye kumiswa uye kumiswa.

3. Chemical kuita kwe carboxymethyl cellelose

Cellulose alkalization reaction:

[C6H7O2 (OH) 3] N + NNAH → NNAH7O2 (OH) 2ona] n + Nh2o] N + NH2O

Iyo ertification yekuita yemochloroacetic acid mushure mekunge Alkali cellulose:

[C6H7O2 (Ah) 2ona] n + nclch2coona → [c6h7o2 (o) 2och2coona] n +C

Saka: iyo makemal formaula yekugadzira carboxymeym cellevelose is: cell-o-ch2-coona nacmc

Sodium carboxymethyl cellelose.

4. Chigadzirwa hunhu hwe carboxymethyl cellelose

1. Kuchengetedza kweCMC Makwikwi mhinduro: Iyo yakagadzikana pasi pekudziya kwezuva kana zuva, asi acidity uye alkalinity yemhinduro ichachinja nekuda kwekuchinja kwekushisa. Pasi pesimba rekusimudzira ultraviolet kana hutachiona, iwo mikana yemhinduro mhinduro ichaderera kana kutokundwa. Kana refu-refu yekuchengetedza inodikanwa, chengetedzo yakakodzera inofanira kuwedzerwa.

2. Kugadzirira nzira yeCMC Makwikwi Mhinduro: Ita kuti zvidimbu zvive zvekunyorova kutanga, izvo zvinogona kuwedzera zvakanyanya kuwanda.

3. CMC ndeye hygroscopic uye inofanira kuchengetedzwa kubva mukunyorova panguva yekuchengetedza.

4. Simbi inorema sesimbi yakadai seZinc, mhangura, aluminium, sirivheri, simbi, tini, uye chromium inogona kukonzera cmc kuti isarudze.

5. Prepication inoitika mumhinduro yemamiriro ekunze pazasi pH2.5, iyo inogona kudzoreredzwa mushure mekusaradzikiswa nekuwedzera Alkali.

7. CMC inoenderana nedzimwe gluble glues, vanyoro uye vanoona.

8. Nekuda kwekugadzirisa kwakasiyana, kutaridzika kweCMC kunogona kuve kwakanaka powder, zviyo zvezviyo kana zviyo, izvo hazvina chekuita nezvinhu zvemuviri uye zvemakemikari.

9. Iyo nzira yekushandisa cmc poda iri nyore. Inogona kuwedzerwa zvakananga uye yakanyungudutswa mumvura inotonhora kana mvura inodziya pa40-50 ° C.

5. Degree rekutsiva uye solubility ye carboxymethyl cellelose

Dhigirii rekutsiva rinoreva nhamba yepakati yeiyo sodium carboxymethyl mapoka akasungirirwa kune yega yega cellulose unit; Iko kukosha kwakanyanya kweiyo degree rekutsiva ndeye 3, asi iyo inonyanya kubatsira ndeye NACMC ine degree rekutsiva kubva pa0,2 kusvika 1.2. Zvivakwa zveNacmc nedhigiri rekutsiva kwe1,2 Iyo yekutanga inongova zvishoma nezvishoma muH ph 7 mvura, asi iyo yekupedzisira haina kunyatsoita. Izvo zvinopesana ndezvechokwadi pasi pemamiriro ealkaline.

6. Polymerization degree uye viscosity ye carboxymethyl cellelose

Polymerization degree: zvinoreva kureba kweiyo cellulose keteni, iyo inosarudza vhiza. Iyo yakareba iyo cellulose keteni, iyo yakakura viscosity, uye ndizvo zvakaita ndiyo mhinduro yeNacMC.

Viscosity: Nacmc Solution ndeye isiri-Newtonian fluid, uye yayo inooneka viscosity inoderera kana iyo Shedhe Simba Inowedzera. Mushure mekusimudzira kwakamiswa, visikoka yakawedzera kuenderana kusvikira yagara yakagadzikana. Ndokunge, mhinduro yacho ndeye thisiopic.

7. Kushandiswa renji ye carboxymethyl cellelose

1. Kuvakwa uye Ceramic Indasitiri

. hapana anogadzika, kutadza kwakanaka; yakanaka yakanaka mhedzisiro, inogadziriswa coating viscossity.
