1. Sumo Pfupi yeCarboxymethyl Cellulose
Zita reChirungu: Carboxyl methyl Cellulose
Mhedziso: CMC
Iyo molecular formula inosiyana: [C6H7O2(OH)2CH2COONA]n
Kuonekwa: chena kana chiedza chero fibrous granular powder.
Kunyungudika kwemvura: inonyungudika nyore mumvura, ichigadzira yakajeka viscous colloid, uye mhinduro haina kwayakarerekera kana zvishoma alkaline.
Zvimiro: Yakakwira mamorekuru musanganiswa wepamusoro inoshanda colloid, isina kunhuhwirira, isinganakidze uye isina chepfu.
Natural cellulose yakagovaniswa zvakanyanya mune zvakasikwa uye ndiyo yakanyanya kuwanda polysaccharide. Asi mukugadzirwa, cellulose inowanzovapo muchimiro che sodium carboxymethyl cellulose, saka zita rakazara rinofanira kunge riri sodium carboxymethyl cellulose, kana CMC-Na. Inoshandiswa zvakanyanya muindasitiri, kuvaka, mushonga, chikafu, machira, ceramics uye mamwe minda.
2. Carboxymethyl cellulose teknolojia
Iyo tekinoroji yekugadziridza ye cellulose inosanganisira: etherification uye esterification.
Shanduko ye carboxymethyl cellulose: carboxymethylation reaction mu etherification tekinoroji, cellulose is carboxymethylated kuwana carboxymethyl cellulose, inonzi CMC.
Mabasa e carboxymethyl cellulose aqueous solution: thickening, firimu kuumba, bonding, kuchengetedza mvura, colloid kudzivirira, emulsification uye kumiswa.
3. Chemical reaction ye carboxymethyl cellulose
Cellulose alkalization maitiro:
[C6H7O2(OH) 3]n + nNaOH→[C6H7O2(OH) 2ONA ]n + nH2O
Iyo etherification reaction ye monochloroacetic acid mushure me alkali cellulose:
[C6H7O2(OH) 2Ona ]n + nClCH2COONA →[C6H7O2(OH) 2OCH2COONA ]n + nNaC
Naizvozvo: iyo kemikari formula yekugadzira carboxymethyl cellulose ndeye: Cell-O-CH2-COONA NaCMC.
Sodium carboxymethyl cellulose(NaCMC kana CMC kwenguva pfupi) imvura inonyungudika selulosi ether inogona kuita kuti viscosity yeanonyanya kushandiswa aqueous solution formulations inosiyana kubva paCP shoma kusvika kuzviuru zvakati cP.
4. Chigadzirwa maitiro e carboxymethyl cellulose
1. Kuchengetwa kweCMC aqueous solution: Yakagadzikana pasi pekushisa kwakadzika kana chiedza chezuva, asi acidity uye alkalinity yemhinduro ichachinja nekuda kwekushanduka kwekushisa. Pasi pesimba re ultraviolet rays kana microorganisms, viscosity yemhinduro inoderera kana kutoora. Kana kuchengetwa kwenguva refu kuchidiwa, mushonga wakakodzera unofanira kuwedzerwa.
2. Kugadzirira nzira yeCMC aqueous solution: ita kuti zvidimbu zvifanane zvakanyorova kutanga, izvo zvinogona kuwedzera zvakanyanya kuparara kwehuwandu.
3. CMC ndeye hygroscopic uye inofanira kuchengetedzwa kubva kune unyoro panguva yekuchengetedza.
4. Heavy metal salts yakadai sezingi, mhangura, lead, aruminiyamu, sirivha, iron, tini, uye chromium zvinogona kukonzera CMC kunayisa.
5. Kunaya kwemvura kunoitika mumushonga wemvura uri pazasi pePH2.5, unogona kudzoserwa mushure mekusarereka nekuwedzera alkali.
6. Kunyange zvazvo munyu wakadai se calcium, magnesium uye tafura yemunyu usina mvura inonaya paCMC, inoderedza viscosity yemhinduro.
7. CMC inowirirana nemamwe glue-soluble glues, softeners uye resins.
8. Pamusana pekugadzirisa kwakasiyana-siyana, kuonekwa kweCMC kunogona kuva poda yakaisvonaka, zviyo zvakakora kana fibrous, iyo isina chokuita nemuviri uye makemikari zvinhu.
9. Nzira yekushandisa CMC powder iri nyore. Inogona kuwedzerwa zvakananga uye yakanyungudutswa mumvura inotonhora kana mvura inodziya pa40-50 ° C.
5. Dhigirii yekutsiva uye solubility ye carboxymethyl cellulose
Iyo dhigirii yekutsiva inoreva avhareji yenhamba ye sodium carboxymethyl mapoka akabatanidzwa kune yega yega cellulose unit; iyo yakanyanya kukosha yedhigirii yekutsiva i3, asi inonyanya kubatsira mumaindasitiri iNaCMC ine dhigirii rekutsiva rinosiyana kubva pa0.5 kusvika 1.2. Zvimiro zveNaCMC zvine dhigirii rekutsiva 0.2-0.3 zvakasiyana chaizvo neizvo zveNaCMC zvine dhigirii rekutsiva 0.7-0.8. Iyo yekutanga inongonyungudika zvishoma mupH 7 mvura, asi iyo yekupedzisira inonyungudika zvachose. Zvakapesana ndezvechokwadi pasi pemamiriro e alkaline.
6. Polymerization degree uye viscosity ye carboxymethyl cellulose
Polymerization degree: inoreva kureba kwecheni ye cellulose, iyo inosarudza viscosity. Iyo yakareba iyo cellulose cheni, iyo yakakura viscosity, uye ndizvo zvakaita mhinduro yeNaCMC.
Viscosity: NaCMC mhinduro isiri yeNewtonian fluid, uye inooneka viscosity inodzikira kana shear simba rawedzera. Mushure mekubvongodza kwakamira, viscosity yakawedzera zvakaenzana kusvika yaramba yakagadzikana. Ndiko kuti, mhinduro ndeye thixotropic.
