1. Nkowa okwu nke Carboxymethyl Cellulose
Aha Bekee: Carboxyl methyl Cellulose
Ndebiri: CMC
Usoro ihe omimi dị iche iche: [C6H7O2(OH)2CH2COONa]n
Ọdịdị: ọcha ma ọ bụ ìhè odo fibrous granular ntụ ntụ.
Mmiri solubility: mfe soluble na mmiri, na-akpụ a transperent viscous colloid, na ngwọta bụ na-anọpụ iche ma ọ bụ ubé alkaline.
Atụmatụ: Ngwakọta molekụla dị elu nke elu colloid na-arụ ọrụ, enweghị isi, enweghị ụtọ na adịghị egbu egbu.
A na-ekesa cellulose eke na okike na ọ bụ polysaccharide kachasị ukwuu. Ma na mmepụta, cellulose na-adịkarị n'ụdị sodium carboxymethyl cellulose, ya mere aha zuru ezu kwesịrị ịbụ sodium carboxymethyl cellulose, ma ọ bụ CMC-Na. A na-ejikarị ya na ụlọ ọrụ, ihe owuwu, ọgwụ, nri, textiles, ceramics na ubi ndị ọzọ.
2. Carboxymethyl cellulose technology
Nkà na ụzụ mgbanwe nke cellulose gụnyere: etherification na esterification.
Mgbanwe nke carboxymethyl cellulose: carboxymethylation mmeghachi omume na etherification technology, cellulose bụ carboxymethylated iji nweta carboxymethyl cellulose, zoro aka dị ka CMC.
Ọrụ nke carboxymethyl cellulose aqueous ngwọta: ndim, film akpụ, bonding, mmiri njigide, colloid nchedo, emulsification na nkwusioru.
3. Chemical mmeghachi omume nke carboxymethyl cellulose
Mmeghachi omume cellulose alkalization:
[C6H7O2(OH) 3]n + nNaOH→[C6H7O2(OH) 2ONa ]n + nH2O
Mmeghachi omume etherification nke monochloroacetic acid mgbe alkali cellulose gasịrị:
[C6H7O2(OH) 2ONa ]n + nClCH2COONa →[C6H7O2(OH) 2OCH2COONa ]n + nNaC
Ya mere: usoro kemịkalụ maka imepụta carboxymethyl cellulose bụ: Cell-O-CH2-COONa NaCMC
sodium carboxymethyl cellulose(NaCMC ma ọ bụ CMC maka nkenke) bụ cellulose ether na-agbaze mmiri nke nwere ike ime ka viscosity nke usoro ngwọta mmiri na-ejikarị dị iche iche site na cP ole na ole ruo ọtụtụ puku cP.
4. Njirimara ngwaahịa nke carboxymethyl cellulose
1. Nchekwa nke CMC aqueous ngwọta: Ọ na-adịgide adịgide n'okpuru obere okpomọkụ ma ọ bụ ìhè anyanwụ, ma acidity na alkalinity nke ngwọta ga-agbanwe n'ihi mgbanwe okpomọkụ. N'okpuru mmetụta nke ụzarị ultraviolet ma ọ bụ microorganisms, viscosity nke ngwọta ga-ebelata ma ọ bụ ọbụna mebie. Ọ bụrụ na achọrọ nchekwa ogologo oge, a ga-agbakwunye ihe nchekwa kwesịrị ekwesị.
2. Nkwadebe usoro nke CMC aqueous ngwọta: mee ka ahụ uniformly mmiri mbụ, nke nwere ike budata dịkwuo mgbasa ọnụego.
3. CMC bụ hygroscopic na kwesịrị ichebe ya na mmiri n'oge nchekwa.
4. Nnu metal dị arọ dị ka zinc, ọla kọpa, lead, aluminum, silver, iron, tin, na chromium nwere ike ime ka CMC na-agbapụta.
5. Mmiri ozuzo na-eme na ngwọta mmiri dị n'okpuru PH2.5, nke nwere ike nwetaghachi mgbe nkwụsịtụ site na ịgbakwunye alkali.
6. Ọ bụ ezie na nnu dị ka calcium, magnesium na nnu tebụl adịghị enwe mmetụta mmiri ozuzo na CMC, ha ga-ebelata viscosity nke ngwọta.
7. CMC dakọtara na ihe ndị ọzọ na-edozi mmiri, ihe nro na resins.
8. N'ihi nhazi dị iche iche, ọdịdị nke CMC nwere ike ịbụ ezigbo ntụ ntụ, ọka na-adịghị mma ma ọ bụ fibrous, nke na-enweghị ihe jikọrọ ya na ihe anụ ahụ na nke kemịkal.
9. Usoro nke iji CMC ntụ ntụ dị mfe. Enwere ike ịgbakwunye ya ozugbo wee gbazee na mmiri oyi ma ọ bụ mmiri ọkụ na 40-50 ° C.
5. Degree nke nnọchi na solubility nke carboxymethyl cellulose
Ogo nke nnọchi na-ezo aka na nkezi ọnụ ọgụgụ nke sodium carboxymethyl otu jikọtara na nke ọ bụla cellulose unit; Uru kacha elu nke ogo ngbanwe bụ 3, mana nke kacha baa uru na ụlọ ọrụ bụ NaCMC nwere ogo nnọchi dị iche site na 0.5 ruo 1.2. Njirimara nke NaCMC nwere ogo ngbanwe nke 0.2-0.3 dị nnọọ iche na nke NaCMC nwere ogo nnọchi nke 0.7-0.8. Nke mbụ bụ naanị akụkụ nke soluble na mmiri pH 7, mana nke ikpeazụ bụ soluble kpamkpam. Ihe dị iche bụ eziokwu n'okpuru ọnọdụ alkaline.
