Sodium carboxymethylcellulose (NaCMC) ndi carboxymethylcellulose (CMC) onse amachokera ku cellulose, polima wachilengedwe wopezeka m'makoma a cellulose. Mankhwalawa amagwira ntchito m'mafakitale osiyanasiyana, kuphatikiza chakudya, mankhwala, nsalu, ndi zina.
Sodium Carboxymethylcellulose (NaCMC):
1.Mapangidwe a Chemical:
NaCMC imachotsedwa ku cellulose kudzera munjira yosintha mankhwala. Magulu a Carboxymethyl (-CH2-COOH) amalowetsedwa mu cellulose, ndipo ayoni a sodium amalumikizidwa ndi magulu awa.
Mchere wa sodium wa CMC umapereka kusungunuka kwamadzi ku polima.
2. Kusungunuka:
NaCMC imasungunuka m'madzi ndipo imapanga yankho la viscous. Kukhalapo kwa ayoni a sodium kumawonjezera kusungunuka kwake m'madzi poyerekeza ndi mapadi osasinthidwa.
3. Mawonekedwe ndi ntchito:
Imagwira ntchito ngati thickener, stabilizer ndi kusunga madzi m'njira zosiyanasiyana.
Imawonetsa pseudoplastic kapena kumeta ubweya wa ubweya, kutanthauza kuti mamasukidwe ake amachepa akamameta ubweya.
4. Kugwiritsa ntchito:
Makampani a Chakudya: Amagwiritsidwa ntchito ngati chokhuthala muzakudya monga sosi, ayisikilimu ndi zinthu zowotcha.
Mankhwala: Ogwiritsidwa ntchitom'mapangidwe ake omangiriza komanso owonjezera kukhuthala.
Kubowola mafuta: kumagwiritsidwa ntchito kuwongolera kukhuthala komanso kutayika kwamadzi m'madzi obowola.
5. Kupanga:
Amapangidwa ndi zomwe cellulose ndi sodium hydroxide ndi monochloroacetic acid.
Carboxymethylcellulose (CMC):
1.Mapangidwe a Chemical:
CMC mu njira yotakata imatanthawuza mawonekedwe a carboxymethylated a cellulose. Zitha kukhala kapena ayizokhudzana ndi sodium ions.
Magulu a carboxymethyl amalowetsedwa mumsana wa cellulose.
2. Kusungunuka:
CMC ikhoza kukhalapo m'njira zambiri, kuphatikizapo mchere wa sodium (NaCMC) ndi mchere wina monga calcium CMC (CaCMC).
CMC sodium ndiye mawonekedwe osungunuka kwambiri m'madzi, koma kutengera ndikugwiritsa ntchito, CMC imathanso kusinthidwa kuti ikhale yosasungunuka m'madzi.
3. Features ndi functipa:
Zofanana ndi NaCMC, CMC imayamikiridwa chifukwa cha kukhuthala, kukhazikika, komanso kusunga madzi.
Kusankha kwa CMC type (sodium, calcium, etc.) zimadalira katundu wofunidwa wa mankhwala omaliza.
4. Kugwiritsa ntchito:
Amagwiritsidwa ntchito kwambiri m'makampani azakudya, mankhwala, nsalu, ceramics ndi kupanga mapepala.
Mawonekedwe osiyanasya CMC ikhoza kusankhidwa kutengera zomwe mukufuna kugwiritsa ntchito.
5. Kupanga:
Carboxymethylation ya cellulose ingaphatikizepo machitidwe osiyanasiyana ndi ma reagents, zomwe zimapangitsa kuti pakhale mitundu yosiyanasiyana ya CMC.
Kusiyana kwakukulu pakati pa sodium CMC ndi CMC ndi kukhalapo kwa ayoni a sodium. Sodium CMC imatanthauza mchere wa sodium wa carboxymethyl cellulose, womwe umasungunuka kwambiri m'madzi. CMC, kumbali ina, ndi mawu okulirapo omwe amaphatikiza mitundu yosiyanasiyana ya cellulose ya carboxymethylated, kuphatikiza sodium ndi mchere wina, iliyonse ili ndi zida zake ndi ntchito zake. Kusankha pakati pa sodium CMC ndi CMC kumatengera zomwe mukufuna kugwiritsa ntchito komanso zomwe mukufuna pazomaliza.
