Carboxymethylcellulose (cmc) ndi methyllulose (MC) onse ndi otaya mtima wa cellulose, polymer achilengedwe omwe amapezeka m'makoma a cell a mbewu. Izi zimapeza ntchito zochulukirapo m'mafakitale osiyanasiyana chifukwa cha malo awo apadera. Ngakhale kuti zoterezi, CMC ndi MC ali ndi kusiyana kosiyana m'mapangidwe awo, katundu, ntchito, kugwiritsa ntchito mafakitale.
Kapangidwe ka 1.Chemical:
Carboxymethylcellulose (CMC):
CMC imapangidwa ndi kusinthika kwa cellulose yokhala ndi ma acid acid, chifukwa cholowa m'malo mwa magulu a hydroxyl (-Oh) pamphepete mwa ma cellamase ndi ma carboxymethyl (-K2cooh).
Mulingo wa zolowa m'malo mwa cmc amatanthauza kuchuluka kwa mabatani a carboxymethyl pa ulalo wa sclucose mu cellulose unyolo. Izi zimapangitsa kuti katundu wa cmc, kuphatikizapo kusungunuka, mafakisoni, ndi achinyengo.
Methylcellulose (MC):
MC imapangidwa ndi magulu a ma hydroxyl m'magulu a cellulose ndi magulu a methyl (-ch3) kudzera pakusintha.
Zofanana ndi CMC, katundu wa MC amapangidwira ndi digiri ya kuloweza, zomwe zimatsimikizira kukula kwa methylation m'mphepete mwa ma cellulose.
2.Solubility:
Carboxymethylcellulose (CMC):
CMC imasungunuka m'madzi ndi mitundu yowoneka bwino, mayankho a viscous.
Kusungunuka kwake ndi kh-wodalirika, ndikusungunuka kwapamwamba mu milkaline.
Methylcellulose (MC):
MC imasungunuka m'madzi, koma kususuka kwake kumakhala kutentha.
Akasungunuka m'madzi ozizira, MC amapanga gel, omwe amasungunula nthawi yotenthetsera. Katunduyu amapangitsa kuti ikhale yoyenera pazomwe zimafunikira kuti azilamulira.
3.Koma:
CMC:
Imawonetsa mafayilo apamwamba m'matumba am'madzi, omwe amathandizira kukula kwake.
Makulidwe ake amatha kusinthidwa ndikusintha zinthu monga kuphatikizira, mulingo wazolowa, ndi Ph.
Mc:
Imawonetsa mawonekedwe a mafayilo ofanana ndi cmc koma nthawi zambiri amakhala owoneka bwino.
Maonekedwe a mac mayankho a MC amathanso kuwongoleredwa ndi kusintha magawo monga kutentha ndi kukhazikika.
Mapangidwe a 4.film:
CMC:
Mafilimu omveka bwino, osinthika osinthika atachotsedwa pamankhwala ake am'madzi.
Makanema awa amapeza mapulogalamu m'makampani monga chakudya chomwe chameza ndi mankhwala.
Mc:
Amathanso kupanga mafilimu koma amakhala ndi mafilimu ambiri poyerekeza ndi mafilimu a CMC.
5.
CMC:
Chogwiritsidwa ntchito kwambiri ngati chitchinga, chitsitsi, ndi emulsifier mu chakudya chomwe chimakhala ndi ayisikilimu, msuzi, ndi mavalidwe.
Kutha kwake kusintha kapangidwe kazinthu komanso pakamwa pazakudya kumapangitsa kuti ikhale yofunika kwambiri.
Mc:
Kugwiritsidwa ntchito pazofanana ndi cmc mu chakudya, makamaka pazomwe zimafuna kupangika kwa gel komanso kukhazikika.
6.ufarocemicals:
CMC:
Zogwiritsidwa ntchito mu mankhwala opanga mankhwala ngati chofunda, kusazindikira, ndi usckisonier mu piritsi.
Kugwiritsanso ntchito mapangidwe apamwamba monga mafuta ndi ma gels chifukwa cha zoopsa zake.
Mc:
Nthawi zambiri imagwiritsidwa ntchito ngati thickener ndi gelling wothandizila ku mankhwala opangira mankhwala, makamaka m'mankhwala am'makamwa am'madzi ndi ma ophthalmic.
7.
CMC:
Opezeka mu zinthu zosiyanasiyana zamunthu monga mano, smempuo, ndi mafuta odzola ngati chibichiro.
Mc:
Kugwiritsidwa ntchito mofananamo monga cmc, kumathandizira kapangidwe kake ndi kukhazikika kwa mawonekedwe amwini.
8. Ntchito:
CMC:
Olemba ntchito m'mafakitale monga zolembedwa, pepala, ndi ma ceramic kuti amatha kukhala ngati binder, rhelogy osintha, komanso wosunga madzi.
Mc:
Imapeza kugwiritsa ntchito zomangamanga, utoto, ndi zomatira chifukwa cha zokulirapo komanso zomangira.
Pomwe Carboxymethylcellulose (CMC) ndi methyllulose (MC) ndi ma cellulose omwe ali ndi matchulidwe omwe ali ndi mafakitale osiyanasiyana, amawonetsa mawonekedwe m'machitidwe awo, machitidwe, maluso a Masu, Mavidiyo A Visckisince. Kumvetsetsa zosiyanitsa izi ndikofunikira posankha zochokera kuzomwe zimagwiritsidwa ntchito makamaka pamakampani osiyanasiyana, kuyambira pazakudya ndi mankhwala othandizira payekha ndi mafakitale. Kaya ndi kufunika kwa Thicker yowoneka bwino ngati masentimita pazakudya kapena kutentha komwe kumachitika monga mc mu mankhwala osokoneza bongo, omwe amapereka amapereka zabwino zapadera pazofunikira m'magulu osiyanasiyana.
