1. Intshayelelo emfutshane yeCarboxymethyl Cellulose
Igama lesiNgesi: iCarboxyl methyl Cellulose
Isifinyezo: CMC
Ifomula yemolekyuli iyaguquguquka: [C6H7O2(OH)2CH2COONa]n
Inkangeleko: umgubo omhlophe okanye otyheli okhanyayo one-fibrous granular powder.
Ukunyibilika kwamanzi: kulula ukunyibilika emanzini, okwenza i-colloid ecacileyo ene-viscous, kwaye isisombululo asithathi cala okanye sine-alkaline kancinci.
Iimpawu: Ikhompawundi ephezulu yeemolekyuli ze-colloid esebenzayo kumphezulu, ayinavumba, ayinancasa kwaye ayinatyhefu.
I-cellulose yendalo isasazeke kakhulu kwindalo kwaye yeyona polysaccharide ininzi. Kodwa kwimveliso, i-cellulose idla ngokubakho ngohlobo lwe-sodium carboxymethyl cellulose, ngoko ke igama elipheleleyo kufuneka libe yi-sodium carboxymethyl cellulose, okanye i-CMC-Na. Isetyenziswa kakhulu kushishino, ulwakhiwo, amayeza, ukutya, ilaphu, iiseramikhi kunye neminye imimandla.
2. Itekhnoloji yeCarboxymethyl cellulose
Itekhnoloji yokuguqula i-cellulose ibandakanya: i-etherification kunye ne-esterification.
Utshintsho lwe-carboxymethyl cellulose: i-carboxymethylation reaction kwi-etherification technology, i-cellulose i-carboxymethylated ukuze ifumane i-carboxymethyl cellulose, ebizwa ngokuba yi-CMC.
Imisebenzi yesisombululo samanzi se-carboxymethyl cellulose: ukuqina, ukwakheka kwefilimu, ukubopha, ukugcinwa kwamanzi, ukukhuselwa kwe-colloid, i-emulsification kunye nokumiswa.
3. Indlela esebenza ngayo ikhemikhali ye-carboxymethyl cellulose
Impendulo ye-cellulose alkalization:
[C6H7O2(OH) 3]n + nNaOH→[C6H7O2(OH) 2ONa ]n + nH2O
Impendulo ye-etherification ye-monochloroacetic acid emva kwe-alkali cellulose:
[C6H7O2(OH) 2ONa ]n + nClCH2COONa →[C6H7O2(OH) 2OCH2COONa ]n + nNaC
Ngoko ke: ifomula yekhemikhali yokwenza i-carboxymethyl cellulose yile: I-Cell-O-CH2-COONa NaCMC
I-sodium carboxymethyl cellulose(NaCMC okanye CMC ngamafutshane) yi-ether ye-cellulose enyibilikayo emanzini enokwenza i-viscosity ye-aqueous solutions ezisetyenziswa kakhulu yahluke ukusuka kwi-cP ezimbalwa ukuya kumawaka aliqela e-cP.
4. Iimpawu zemveliso ye-carboxymethyl cellulose
1. Ukugcinwa kwesisombululo samanzi se-CMC: Sizinzile phantsi kobushushu obuphantsi okanye ukukhanya kwelanga, kodwa i-asidi kunye ne-alkalinity yesisombululo ziya kutshintsha ngenxa yotshintsho lobushushu. Phantsi kwempembelelo yemitha ye-ultraviolet okanye ii-microorganisms, i-viscosity yesisombululo iya kuncipha okanye yonakale. Ukuba kufuneka ukugcinwa ixesha elide, kufuneka kongezwe isithinteli esifanelekileyo.
2. Indlela yokulungiselela isisombululo samanzi se-CMC: yenza amasuntswana abe manzi ngokulinganayo kuqala, nto leyo enokunyusa kakhulu izinga lokunyibilika.
3. I-CMC ayixutywanga kakuhle kwaye kufuneka ikhuselwe kumswakama ngexesha lokugcina.
4. Iityuwa zesinyithi ezinzima ezifana ne-zinc, i-copper, i-lead, i-aluminium, isilivere, i-iron, i-tin, kunye ne-chromium zinokubangela ukuba i-CMC ivuthe.
5. Ukuna kwemvula kwenzeka kwisisombululo samanzi esingaphantsi kwe-PH2.5, esinokufunyanwa emva kokuthomalalisa ngokongeza i-alkali.
6. Nangona iityuwa ezifana ne-calcium, i-magnesium kunye netyuwa yetafile zingenawo umphumo wokuna kwemvula kwi-CMC, ziya kunciphisa ukuxinana kwesisombululo.
7. I-CMC iyahambelana nezinye izincamathelisi ezinyibilikayo emanzini, izithambisi kunye neeresini.
8. Ngenxa yokucubungula okwahlukeneyo, imbonakalo ye-CMC ingaba ngumgubo ocolekileyo, iinkozo ezirhabaxa okanye i-fibrous, engenanto yakwenza neempawu zomzimba nezekhemikhali.
9. Indlela yokusebenzisa umgubo we-CMC ilula. Ingongezwa ngqo kwaye inyibilikiswe emanzini abandayo okanye emanzini afudumeleyo kwi-40-50°C.
5. Ubungakanani bokutshintshwa kunye nokunyibilika kwe-carboxymethyl cellulose
Inqanaba lokutshintshwa libhekisa kwinani eliqhelekileyo lamaqela e-sodium carboxymethyl aqhotyoshelwe kwiyunithi nganye ye-cellulose; ixabiso eliphezulu lenqanaba lokutshintshwa yi-3, kodwa eyona iluncedo kakhulu kwishishini yi-NaCMC eneqondo lokutshintshwa elihluka ukusuka kwi-0.5 ukuya kwi-1.2. Iipropati ze-NaCMC ezineqondo lokutshintshwa le-0.2-0.3 zahluke kakhulu kwezo ze-NaCMC ezineqondo lokutshintshwa le-0.7-0.8. Eyokuqala inyibilika kancinci kuphela emanzini e-pH 7, kodwa eyokugqibela inyibilika ngokupheleleyo. Okuchaseneyo kuyinyani phantsi kweemeko ze-alkaline.
6. I-polymerization degree kunye ne-viscosity ye-carboxymethyl cellulose
I-polymerization degree: ibhekisa kubude be-cellulose chain, emisela i-viscosity. Okukhona i-cellulose chain inde, kokukhona i-viscosity inkulu, kwaye nesisombululo se-NaCMC sinjalo.
Ukuqina: Isisombululo seNaCMC lulwelo olungelulo ulwelo lweNewtonian, kwaye ukuqina kwaso okubonakalayo kuncipha xa amandla okucheba enyuka. Emva kokuba kumiswe ukuxutywa, ukuqina kwanda ngokulinganayo de kwahlala kuzinzile. Oko kukuthi, isisombululo sithixotropic.
