Nigute ushobora kumenya ubwiza bwa hydroxypropyl methyl?

01. Itandukaniro riri hagati ya hydroxypropyl methyl yimpimbano na hydroxypropyl methyl yo mu rwego rwo hejuru

Kugaragara: Krahisi yera HPCM igaragara cyane, hagati ya 0.3 na 0.4 g / ml. Amylum ihuza ibinyamisogwe bityo HPCM ni isukari kandi idahangayikishijwe cyane nuburozi busanzwe.

Ibisabwa: ibinyamisogwe byuzuye ibinyamisogwe, ifu ya hpm, fibre munsi ya microscope cyangwa ikirahure kinini, HPCM ubwoko bwa krahisi ishobora kugenzura ibinyamisogwe cyangwa ibinyamisogwe n'ibinyomoro.

Impumuro: hydroxypropyl methylcellulose HPMC ntishobora kunuka ammonia, ibinyamisogwe n'inzoga; gusambana hydroxypropyl methylcellulose HPMC irashobora kunuka impumuro zose, niyo yaba itaryoshye, izumva ifite intege nke Shen.

Igisubizo cyamazi: cyera, HPMC methylcellulose demethoxypropyl brinzolamide igisubizo cyamazi kirasobanutse, igipimo cyo gufata amazi yoroheje ≥ 97%; hydrolized hydrolyzed selulose-ivanze na HPMC hydrolyzed selulose irushijeho kuba mibi, igipimo cyo gufata amazi kigera kuri 80%.

22. Kubungabunga methyl selulose ku bushyuhe bwo hejuru ni ikimenyetso cyingenzi cyo kumenya ubwiza bwa methyl selulose ether. Ibintu nkubushyuhe bwikirere, ubushyuhe bwikirere n'umuvuduko wumuyaga bigira ingaruka kumihindagurikire ya sima ya sima nibicuruzwa bya gypsumu. Kubwibyo, wongeyeho ibicuruzwa bimwe bya HPMC mubihe bitandukanye, hariho itandukaniro mubikorwa byo kuzigama amazi. Mubikorwa byihariye byakazi, ingaruka za serosa zohejuru zirashobora gukosorwa mugabanya umubare wa HPMC wongeyeho. Hydroxypropyl methylcellulose yo mu rwego rwo hejuru HPMC irashobora gukemura neza ikibazo cyo gufata amazi menshi.

Methyl selulose yo mu rwego rwohejuru irashobora gukwirakwizwa neza kandi neza mugisima cya sima hamwe nibicuruzwa byapompa, bigakora firime ikomeye, igenda isohoka buhoro buhoro kuva murwego rwibanze kandi igakora hydrophilique reaction hamwe nibikoresho byo gutembera mu buryo butemewe, bityo bigatuma imbaraga nubukomere bikomera. HPMC selulose methyl propoxylate yujuje ubuziranenge kandi irasa, kandi ogisijeni ya Ethyl bromide hamwe na acide ya protionic acide ya selile ya selile ya selile ni imwe, iteza imbere ogisijeni na hydrogène ihuza buri atom yingenzi ya hydroxyl na ether Amazi make arashobora guhindura amazi yubusa mo amazi azigama uruhu, bityo agenzura neza umwuka wuka, kubyara ubushyuhe, nubushuhe buke bushingiye kumazi.

Bitewe nubushyuhe bwo hejuru bwubushyuhe mugihe cyizuba, kugirango tugere ku ngaruka zo kuzigama amazi, birakenewe kongeramo ibicuruzwa byiza bya HPMC ukurikije formulaire, bitabaye ibyo bizatera ibibazo nko gukama cyane, imbaraga nke, guturika, kudakora guhungabana no guta ishuri, no kongera ingorane zo kubaka abakozi. Mugihe cyo kugabanya ubushyuhe, birashoboka kugabanya buhoro buhoro umubare wa HPMC wongeyeho kandi ukabona ingaruka zimwe zo kuzigama amazi.
