1. Hoʻopuka pōkole o Carboxymethyl Cellulose
Ka inoa Pelekane: Carboxyl methyl Cellulose
Pōkole: CMC
He loli ke kumu mole: [C6H7O2(OH)2CH2COONa]n
Ke ʻano: keʻokeʻo a i ʻole melemele māmā fibrous granular pauka.
Hiki ke hoʻoheheʻe wai: hiki ke hoʻoheheʻe ʻia i loko o ka wai, e hana ana i kahi colloid viscous akaka, a ʻo ka hopena he kū ʻole a i ʻole ka alkaline iki.
Nā hiʻohiʻona: High molecular compound of surface active colloid, odorless, tasteless and non-toxic.
Hoʻolaha nui ʻia ka cellulose kūlohelohe i ke ʻano a ʻo ia ka polysaccharide nui loa. Akā i ka hana ʻana, aia ka cellulose ma ke ʻano o ka sodium carboxymethyl cellulose, no laila ʻo ka inoa piha ʻo sodium carboxymethyl cellulose, a i ʻole CMC-Na. Hoʻohana nui ʻia i ka ʻoihana, kūkulu, lāʻau lapaʻau, meaʻai, textile, ceramics a me nā ʻano ʻē aʻe.
2. ʻenehana Carboxymethyl cellulose
Aia ka ʻenehana hoʻololi o cellulose: etherification a me esterification.
Ka hoʻololi ʻana o ka carboxymethyl cellulose: ka hopena carboxymethylation i ka ʻenehana etherification, ʻo ka cellulose ka carboxymethylated e loaʻa ai ka carboxymethyl cellulose, i kapa ʻia ʻo CMC.
Nā hana o ka carboxymethyl cellulose aqueous solution: mānoanoa, hana kiʻiʻoniʻoni, hoʻopaʻa, paʻa wai, pale colloid, emulsification a me ka hoʻokuʻu.
3. Ka hopena kemika o carboxymethyl cellulose
ʻO ka pane ʻana o ka cellulose alkaliization:
[C6H7O2(OH) 3]n + nNaOH→[C6H7O2(OH) 2ONa ]n + nH2O
ʻO ka hopena etherification o ka waikawa monochloroacetic ma hope o ka cellulose alkali:
[C6H7O2(OH) 2ONa ]n + nClCH2COONa →[C6H7O2(OH) 2OCH2COONa ]n + nNaC
No laila: ʻo ke kumu kemika no ka hana ʻana i ka carboxymethyl cellulose ʻo: Cell-O-CH2-COONa NaCMC
ʻO ka sodium carboxymethyl cellulose(NaCMC a i ʻole CMC no ka pōkole) he cellulose ether hiki ke hoʻololi i ka viscosity o nā hoʻoheheʻe wai wai i hoʻohana pinepine ʻia mai kahi cP a i kekahi mau tausani cP.
4. Nā hiʻohiʻona huahana o carboxymethyl cellulose
1. Ka mālama ʻana i ka wai wai CMC: Paʻa ia ma lalo o ka haʻahaʻa haʻahaʻa a i ʻole ka lā o ka lā, akā e loli ka acidity a me ka alkalinity o ka hopena ma muli o nā loli wela. Ma lalo o ka mana o nā kukui ultraviolet a i ʻole nā microorganisms, e emi ana ka viscosity o ka hopena a i ʻole e lilo i pala. Inā makemake ʻia ka mālama ʻana i ka wā lōʻihi, pono e hoʻohui i kahi preservative kūpono.
2. Hoʻomākaukau ʻana o ka CMC aqueous solution: e hoʻomaʻemaʻe i nā ʻāpana ma mua, hiki ke hoʻonui nui i ka helu hoʻoheheʻe.
3. He hygroscopic ka CMC a pono e pale ʻia mai ka makū i ka wā mālama.
4. ʻO nā paʻakai metala kaumaha e like me ka zinc, ke keleawe, ke kēpau, ka aluminika, ke kālā, ka hao, ka tin, a me ka chromium hiki ke hoʻoheheʻe ʻia ka CMC.
5. Hoʻomaka ka ua i loko o ka wai wai ma lalo o PH2.5, hiki ke hoʻihoʻi hou ʻia ma hope o ka neutralization ma ka hoʻohui ʻana i ka alkali.
6. ʻOiai nā paʻakai e like me ka calcium, ka magnesium a me ka paʻakai papa ʻaʻole i loaʻa ka hopena o ka ua ma CMC, e hoʻemi lākou i ka viscosity o ka hopena.
7. Ua kūpono ʻo CMC me nā glues hiki ke hoʻoheheʻe ʻia i ka wai, nā mea palupalu a me nā resins.
8. Ma muli o ke kaʻina hana like ʻole, hiki ke ʻike ʻia ka CMC i ka pauka maikaʻi, ka palaoa a i ʻole ka fibrous, ʻaʻohe mea pili i nā waiwai kino a me nā kemika.
9. He maʻalahi keʻano o ka hoʻohanaʻana i ka pauka CMC. Hiki ke hoʻohui pono ʻia a hoʻoheheʻe ʻia i ka wai anuanu a i ʻole ka wai mahana ma 40-50 ° C.
5. Degere o ka pani a me ka solubility o carboxymethyl cellulose
ʻO ke degere o ka hoʻololi ʻana e pili ana i ka helu awelika o nā hui sodium carboxymethyl i hoʻopili ʻia i kēlā me kēia cellulose; ʻO ka helu kiʻekiʻe o ke degere o ka hoʻololi ʻana he 3, akā ʻo ka mea ʻoi loa i ka hana ʻoihana ʻo NaCMC me kahi degere o ka hoʻololi ʻana mai ka 0.5 a i ka 1.2. ʻOkoʻa loa nā waiwai o NaCMC me kahi pae o ka hoʻololi ʻana o 0.2-0.3 me nā mea o NaCMC me kahi pae o ka hoʻololi ʻana o 0.7-0.8. Hiki ke hoʻoheheʻe ʻia ka mea mua i ka wai pH 7, akā hiki ke hoʻoheheʻe ʻia ka hope. He ʻoiaʻiʻo ka ʻaoʻao ma lalo o nā kūlana alkaline.
6. Polymerization degere a me ka viscosity o carboxymethyl cellulose
Degere polymerization: pili i ka lōʻihi o ke kaulahao cellulose, ka mea e hoʻoholo ai i ka viscosity. ʻO ka lōʻihi o ke kaulahao cellulose, ʻoi aku ka nui o ka viscosity, a pēlā pū ka hopena NaCMC.
Viscosity: He wai non-Newtonian ka hoʻonā NaCMC, a e emi ana kona viscosity i ka wā e piʻi ai ka ikaika ʻā. Ma hope o ka pau ʻana o ka hoʻoulu ʻana, ua hoʻonui ʻia ka viscosity a hiki i ka paʻa. ʻO ia hoʻi, he thixotropic ka hopena.
