Izindlela ezijwayelekile nezilula zokuhlukanisa ikhwalithi ye-HPMC cellulose

Izindlela ezijwayelekile nezilula zokuhlukanisa ikhwalithi ye-HPMC cellulose:

1. Isimo esibukwayo se-HPMC cellulose ehlanzekile siyi-fluffy, futhi ukuminyana kwenqwaba kuncane, ngebanga elingu-0.3-0.4g/ml; I-HPMC cellulose ehlanganisiwe inoketshezi olungcono nokuzwakala kwesandla esindayo, okuhluke kakhulu ekubukekeni kwemikhiqizo eyiqiniso.

2. Ubumhlophe be-HPMC cellulose emsulwa buhle, okusho ukuthi izinto zokusetshenziswa ezisetshenziswa ekukhiqizeni zimsulwa futhi ukusabela kuphelele ngaphandle kokungcola. Uma kuqhathaniswa nemikhiqizo efanelekile ye-cellulose ether yangaphandle, kungabonakala ukuthi ubumhlophe bomkhiqizo we-cellulose ether omuhle buhlala bungcono kunemikhiqizo yasekhaya yomugqa wesibili.

3. Isixazululo samanzi se-HPMC se-cellulose esihlanzekile sicacile, sinokudluliswa kokukhanya okuphezulu, kanye nezinga lokugcinwa kwamanzi ≥ 97%; Isixazululo se-aqueous se-HPMC se-cellulose esixubile sine-turbid, futhi izinga lokugcinwa kwamanzi linzima ukuhlangabezana nezidingo. Ukudluliswa kokukhanya kwesisombululo se-aqueous kuhle, okubonisa ukuthi umkhiqizo uqukethe izinto ezincane ezingancibiliki kanye nokuqukethwe okuphezulu kwezithako ezisebenzayo.

4. I-cellulose ye-HPMC ehlanzekile akufanele ihogele i-ammonia, isitashi notshwala; I-HPMC cellulose ehlanganisiwe ingavamisa ukuhogela zonke izinhlobo zokunambitheka. Ngisho noma inganambitheki, izozizwa isindayo.

5. I-HPMC cellulose powder ehlanzekile ine-fibrous ngaphansi kwe-microscope noma ingilazi yokukhulisa; I-HPMC cellulose ehlanganisiwe ingabonwa njenge-granular solid noma ikristalu ngaphansi kwesibonakhulu noma ingilazi ekhulisayo.

6. Indlela elula yokuhlola okuqukethwe komlotha we-cellulose ether: kala igremu elilodwa kuya kwamabili e-cellulose ether, uyithungele ngokukhanya, ukale insalela yomlotha eshiywe ukushiswa kwe-cellulose ether, futhi lapho insalela yomlotha / i-cellulose ether ingu-≥ 5 %, ikhwalithi ye-cellulose ether empeleni ayifanelekile. (kwesinye isikhathi kuba namaphutha kule ndlela. Okokuqala, umenzi uhlanganisa imikhiqizo efanele amakhasimende athile ngaphambi kokushiya ifekthri; okwesibili, ama-ejenti noma abakhiqizi bengeza izinto ezivuthayo ezinomlotha omncane lapho konakala)

7. Ezinye izimboni nemizi zisebenzisa inani elincane le-C cellulose elixutshwe ku-hydroxypropyl methyl cellulose ether, futhi lapho isixazululo esinamanzi se-C cellulose sihlangana ne-tin, isiliva, i-aluminium, umthofu, insimbi, ithusi nezinye izinsimbi ezinzima, ukusabela kwemvula kuyokwenzeka; Uma i-c-cellulose i-aqueous solution ihlangana ne-calcium, i-magnesium nosawoti, ngeke ikhiqize imvula, kodwa izonciphisa i-viscosity ye-c-cellulose isixazululo samanzi.

8. Uma izimo zivuma, hlola ngokuqondile i-viscosity yesisombululo esinamanzi se-cellulose ether futhi uqhathanise izinga lokugcinwa kwamanzi kokuqukethwe okuphansi kwe-cellulose ether mortar.

Njengomkhiqizi we-cellulose ether ochwepheshe, u-Yi-cellulose izohlinzeka amakhasimende ngenhliziyo yonke ngemikhiqizo namasevisi ekhwalithi ephezulu kakhulu
