1. Intshayelelo emfutshane yeCarboxymethyl Cellulose
Igama lesiNgesi: Carboxyl methyl Cellulose
Ushunqulelo: CMC
Ifomula yemolekyuli iyaguquguquka: [C6H7O2(OH)2CH2COONA]n
Imbonakalo: umgubo omhlophe okanye okhanyayo omthubi we-fibrous granular.
Ukunyibilika kwamanzi: ukunyibilika ngokulula emanzini, ukwenza i-viscous colloid ecacileyo, kwaye isisombululo asithathi hlangothi okanye i-alkaline kancinane.
Iimpawu: Ikhompawundi ephezulu yemolekyuli yecolloid esebenzayo, ayinavumba, ayinancasa kwaye ayinayo ityhefu.
I-cellulose yendalo isasazwe ngokubanzi kwindalo kwaye yeyona polysaccharide ininzi.Kodwa kwimveliso, i-cellulose ihlala ikhona ngendlela ye-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 namanye amasimi.
2. Iteknoloji ye-Carboxymethyl cellulose
Itekhnoloji yokuguqula i-cellulose ibandakanya: i-etherification kunye ne-esterification.
Ukuguqulwa kwe-carboxymethyl cellulose: i-carboxymethylation reaction kwi-teknoloji ye-etherification, i-cellulose i-carboxymethylated ukufumana i-carboxymethyl cellulose, ebizwa ngokuba yi-CMC.
Imisebenzi ye-carboxymethyl cellulose isisombululo samanzi: ukuqina, ukubunjwa kwefilimu, ukudibanisa, ukugcinwa kwamanzi, ukukhuselwa kwe-colloid, i-emulsification kunye nokumiswa.
3. Ukusabela kweekhemikhali ze-carboxymethyl cellulose
Ukusabela kwi-cellulose alkalization:
[C6H7O2(OH) 3]n + nNaOH→[C6H7O2(OH) 2ONa ]n + nH2O
Ukusabela kwe-etherification ye-monochloroacetic acid emva kwe-alkali cellulose:
[C6H7O2(OH) 2ONa ]n + nClCH2COONA →[C6H7O2(OH) 2OCH2COONA ]n + nNaC
Ke ngoko: ifomula yemichiza yokwenza i-carboxymethyl cellulose yile: Iseli-O-CH2-COONA NaCMC
I-sodium carboxymethyl cellulose(i-NaCMC okanye i-CMC ngokufutshane) yi-ether ye-cellulose e-soluble yamanzi enokwenza i-viscosity yeendlela ezisetyenziswa ngokuqhelekileyo zesisombululo se-aqueous zihluka ukusuka kwi-cP embalwa ukuya kumawaka amaninzi e-cP.
4. Iimpawu zemveliso ye-carboxymethyl cellulose
1. Ukugcinwa kwesisombululo samanzi se-CMC: Izinzile phantsi kobushushu obuphantsi okanye ukukhanya kwelanga, kodwa i-acidity kunye ne-alkalinity yesisombululo iya kutshintsha ngenxa yokutshintsha kweqondo lokushisa.Ngaphantsi kweempembelelo zemitha ye-ultraviolet okanye i-microorganisms, i-viscosity yesisombululo iya kuncipha okanye yonakaliswe.Ukuba ugcino lwexesha elide luyafuneka, kufuneka kongezwe isigcinasi esifanelekileyo.
2. Indlela yokulungiselela isisombululo se-CMC samanzi: yenza amaqhekeza afanayo amanzi kuqala, anokunyusa kakhulu izinga lokuchithwa.
3. I-CMC i-hygroscopic kwaye kufuneka ikhuselwe kumswakama ngexesha lokugcinwa.
4. Iityuwa zentsimbi ezinzima ezifana ne-zinc, ubhedu, ilothe, i-aluminiyam, isilivere, isinyithi, i-tin, kunye ne-chromium zinokubangela ukuba i-CMC iqhube.
5. Imvula ivela kwisisombululo samanzi esingaphantsi kwe-PH2.5, esinokubuyiswa emva kokungathathi hlangothi ngokongeza i-alkali.
6. Nangona iityuwa ezifana ne-calcium, i-magnesium kunye netyuwa yetafile ayinayo i-precipitation effect kwi-CMC, iya kunciphisa i-viscosity yesisombululo.
7. I-CMC iyahambelana nezinye iiglues ezinyibilikayo zamanzi, izinto ezithambileyo kunye ne-resins.
8. Ngenxa yokucutshungulwa okuhlukeneyo, ukubonakala kwe-CMC kunokuba ngumgubo ococekileyo, ingqolowa enqabileyo okanye i-fibrous, engenanto yakwenza nezinto eziphathekayo kunye neekhemikhali.
9. Indlela yokusebenzisa i-CMC powder ilula.Ingongezwa ngokuthe ngqo kwaye ichithwe emanzini abandayo okanye amanzi afudumeleyo kwi-40-50 ° C.
5. Iqondo lokutshintshwa kunye ne-solubility ye-carboxymethyl cellulose
Iqondo lokutshintsha libhekiselele kumyinge wenani lamaqela e-sodium carboxymethyl adityaniswe kwiyunithi nganye ye-cellulose;elona xabiso liphezulu leqondo lokuthatha indawo yi-3, kodwa eyona nto iluncedo kakhulu kwimizi-mveliso yiNaCMC eneqondo lokutshintsha ukusuka ku-0.5 ukuya ku-1.2.Iipropati ze-NaCMC ezineqondo lokutshintshwa kwe-0.2-0.3 zahluke kakhulu kwezo ze-NaCMC kunye neqondo lokutshintshwa kwe-0.7-0.8.Eyangaphambili inyibilika ngokuyinxenye kuphela kwi-pH 7 yamanzi, kodwa le yokugqibela inyibilika ngokupheleleyo.Okuchaseneyo kuyinyaniso phantsi kweemeko ze-alkaline.
6. I-polymerization degree kunye ne-viscosity ye-carboxymethyl cellulose
I-Polymerization degree: ibhekisela kubude bekhonkco le-cellulose, elimisela i-viscosity.Ixesha elide ikhonkco le-cellulose, i-viscosity enkulu, kunye nesisombululo se-NaCMC.
I-Viscosity: Isisombululo se-NaCMC silulwelo olungelulo lwe-Newtonian, kwaye i-viscosity yayo ebonakalayo iyancipha xa amandla okucheba anyuka.Emva kokuba ukuvuselela kumisiwe, i-viscosity yanda ngokulinganayo de yahlala izinzile.Oko kukuthi, isisombululo sithixotropic.
