Kodi pali kusiyana kotani pakati pa CMC ndi MC?

CMC ndi MC onse ndi zotuluka pa cellulose zomwe zimagwiritsidwa ntchito ngati zokhuthala, zomangira, ndi zokhazikika pamagwiritsidwe osiyanasiyana, kuphatikiza mafakitale azakudya, azamankhwala, ndi chisamaliro chamunthu. Komabe, pali kusiyana pakati pa ziwirizi zomwe ziyenera kuzindikila.

CMC, kapena Carboxymethyl Cellulose, ndi polima osungunuka m'madzi omwe amachokera ku cellulose. Amapangidwa pochita ma cellulose ndi sodium chloroacetate ndikusintha ena mwamagulu a hydroxyl pa cellulose kukhala magulu a carboxymethyl. CMC imagwiritsidwa ntchito kwambiri muzakudya, monga zowotcha, mkaka, ndi sosi, komanso pazinthu zosamalira anthu ndi mankhwala.

MC, kapena Methyl Cellulose, ndi polymer yosungunuka m'madzi yomwe imachokera ku cellulose. Amapangidwa pochita ma cellulose ndi methyl chloride ndikusintha ena mwamagulu a hydroxyl pa cellulose kukhala magulu a methyl ether. MC imagwiritsidwa ntchito ngati chokhuthala, chomangira, ndi chokometsera zinthu zosiyanasiyana, kuphatikiza muzakudya, monga sosi, mavalidwe, ndi zotsekemera zoziziritsa kukhosi, komanso m'mankhwala ndi zinthu zosamalira anthu.

Kusiyana kwakukulu pakati pa CMC ndi MC ndi mawonekedwe awo osungunuka. CMC imasungunuka mosavuta m'madzi kuposa MC, ndipo imatha kupanga yankho lomveka bwino komanso lowoneka bwino pazambiri zotsika. MC, kumbali ina, imafuna kuyika kwambiri komanso/kapena kutentha kuti isungunuke m'madzi, ndipo mayankho ake amatha kukhala osawoneka bwino kapena amtambo.

Kusiyana kwina ndi machitidwe awo mumitundu yosiyanasiyana ya pH. CMC imakhala yokhazikika mumikhalidwe ya acidic ndipo imatha kulekerera pH yochulukirapo kuposa MC, yomwe imatha kusweka ndikutaya mphamvu zake zokulirapo m'malo okhala acidic.

Onse a CMC ndi MC ndizochokera ku cellulose zosunthika zomwe zili ndi zinthu zambiri zothandiza pazogwiritsa ntchito zosiyanasiyana. Kusankha kwa omwe angagwiritse ntchito kumatengera zofunikira za pulogalamuyo komanso mawonekedwe omwe mukufuna.
