Hydroxypropyl methyl cellulose VS methyl cellulose

1. Hydroxypropyl methyl celluloseIyo amazi ashyushye ashongeshejwe azahura n'ingorane. Ariko ubushyuhe bwayo bwo gushonga mu mazi ashyushye buri hejuru cyane ugereranyije n'ubwa methyl cellulose. Uburyo methyl cellulose ishongeshejwe mu mazi akonje nabwo burarushaho kwiyongera.

2. Uburemere bwa hydroxypropyl methyl cellulose bufitanye isano n'uburemere bwayo bwa molekile, kandi uburemere bwa molekile bwinshi ni bwo buremere bwinshi. Ubushyuhe buzagira ingaruka ku buremere bwayo, ubushyuhe bwiyongera, uburemere bukagabanuka. Ariko, uburemere bw'ubushyuhe bwinshi buri hasi ugereranyije n'ubwa methyl cellulose. Umuti uba uhamye iyo ubitswe ku bushyuhe bw'icyumba.

3. Hydroxypropyl methyl cellulose irahamye kuri aside na alkali, kandi umuti wayo w’amazi urahamye cyane mu rugero rwa pH = 2 ~ 12. Soda ya Caustic n’amazi y’indimu nta ngaruka nini bigira ku miterere yayo, ariko alkali ishobora kwihutisha umuvuduko wayo wo gushonga no kunoza ubukana bw’agapira. Hydroxypropyl methyl cellulose irahamye kuri umunyu rusange, ariko iyo ubwinshi bw’umunyu buri hejuru, ubukana bw’umuti wa hydroxypropyl methyl cellulose bukunda kwiyongera.

4. Uburyo selulosi ya hydroxypropyl methyl igumana amazi biterwa n'ingano yayo, ubukana bwayo, n'ibindi. Igipimo cyo kubika amazi munsi y'ingano imwe yo kongeramo kiri hejuru kurusha icya selulosi ya methyl.

5. Uburyo hydroxypropyl methyl cellulose ifatana n'imashini ikoze mu buryo bworoshye ni bwinshi kurusha uko methyl cellulose ikora.

6. Hydroxypropyl methyl celluloseifite ubushobozi bwo kudakora neza kwa enzymes kurusha methyl cellulose, kandi amahirwe yo kwangirika kwa enzymes mu gisubizo ni make ugereranyije na methyl cellulose.
