Izakhiwo kanye nokukhonjwa okulula kwe-hydroxypropyllylylylylylylykl methylcellulose

I-Hydroxypropyllylyl hpmc ngokuvamile isetshenziswa ekukhiqizweni kodonga lwangaphakathi nolodonga lwangaphandle lwe-putty putty i-celtule I-VisCosity Cellulose, lo mkhiqizo unomphumela omuhle wokugcina amanzi, umphumela omuhle wokuqina kanye nekhwalithi ezinzile. I-HPMC isetshenziswa kabanzi embonini yezinto zokwakha futhi isetshenziswa ngenani elikhulu. I-cellulose ingasetshenziswa njenge-retarder, i-ejenti yokugcinwa kwamanzi, i-perhener ne-binder. I-Cellulose Ether idlala indima ebalulekile ku-usimende omile osomile, udaka lwangaphandle oludongeni, udaka olomile, udaka, lunethonya lokufaka okuthe xaxa, ukuhlanganiswa kwamanzi, ukuqina, ukuqina, ukubuyiselwa emuva kanye nokusebenza kohlelo lwe-stucco.

I-cellulose tallulose esetshenziswa kaningi ifaka i-HEC, i-HPMC, i-CMC, i-PAC, i-MHEC, njll. I-HPMC, i-MC noma i-EHEC isetshenziswa ekusetshenzisweni kwamathumbu asuselwa kumasimende noma e-gypsum, njengodaka lwamanzi, ukunamathela kosimende, ukuhlanganisa i-Milky Putty, njll. I-HEC isetshenziswa usimende, hhayi kuphela njengomthengisi, kepha futhi njenge-ejenti yokugcina amanzi, futhi i-hehpc nayo isetshenziswa kulokhu. I-MC noma i-HEC imvamisa isetshenziswa kanye ne-CMC njengengxenye eqinile yephephadonga. I-Medium-viscosity noma i-pollulose ephezulu yesulule

Izakhiwo ze-hydroxypropylll methylcellulose

Imikhiqizo ye-Hydroxypropyl methylcellose HPMC ihlanganisa izakhiwo eziningi zomzimba neyomakhemikhali ukuze ibe ngumkhiqizo oyingqayizivele ngokusetshenziswa okuningi. Izakhiwo ezahlukahlukene zimi ngokulandelayo:

(1) Ukugcinwa kwamanzi: Kungabamba amanzi ezindaweni eziphakemeyo ezinjengamabhodi odonga nezitini.

(2) Ukwakheka kwamafilimu: Kungakha ifilimu esobala, enzima futhi ethambile ngokumelana kahle kwamafutha.

.

.

(5) Umsebenzi ongaphezulu

.

(7) I-colloid evikelayo: Kungavimbela amaconsi nezinhlayiya kusuka ekuhlanganeni noma ekuhlanganiseni.

(8) Ukunamathela: Kusetshenziswe njengokunamathela kwemibala, imikhiqizo kagwayi, nemikhiqizo yamaphepha, inokusebenza okuhle kakhulu.

.

.

(11) Ukuqina kwe-acid-base: kufanelekile ukusetshenziswa ngaphakathi kwe-PH3.0-11.0.

(12) Akunambitha futhi awunaphutha, akuthinteki nge-metabolism; Kusetshenziswa njengokudla nezithasiselo zezidakamizwa, ngeke zihlangane ekudleni futhi ngeke zinikeze amakhalori.

Izindlela ezijwayelekile nezilula zokuhlonza ikhwalithi

1. I-HPMC ehlanzekile i-fluffy ebonakalayo futhi inobunzima obuphansi obuphansi, kusukela ku-0.3-0.4g / ml; I-HPMC ephindwe nge-FPMC inobunzima obungcono futhi izizwe isindayo, okusobala okuhlukile kumkhiqizo wangempela ngokubukeka.

2 Uma kuqhathaniswa nemikhiqizo ehlobene ne-cellulose ye-ether yakwamanye amazwe, kungabonakala ukuthi ubumsulwa bomkhiqizo omuhle we-cellulose ether buhlala bungcono kunaleyo yemikhiqizo ye-TIER-TIER yesibili yasekhaya.

3. Isixazululo esimsulwa se-HPMC samanzi sicacile, ukudluliselwa okuphezulu okuphezulu, isilinganiso sokugcinwa kwamanzi ≥ 97%; Isisombululo se-HPMC samanzi se-HPMC siyi-turbid, kanti izinga lokugcina amanzi linzima ukufeza izidingo. Ukudluliselwa kokukhanya kwesisombululo esinamanzi kuhle, okubonisa ukuthi umkhiqizo uqukethe izinto ezingaphansi kwe-insoluble futhi unokuqukethwe okuphezulu kwezithako ezisebenzayo.

I-4. I-HPMC ehlanzekile akufanele ihogela i-ammonia, isitashi notshwala; I-HPMC ye-Aleelped ivame ukunuka zonke izinhlobo zokuhogela, noma ngabe kune-odorless, kuzozizwa zisinda.

I-5. I-pure HPMC powder i-fibrous ngaphansi kwesibonakhulu noma ingilazi ekhulisa; I-HPMC ye-Aleelped ingabhekwa njengezinsimbi ze-granular noma amakristalu ngaphansi kwesibonakhulu noma ingilazi ekhulisa.

6 Lapho i-ash residie ​​/ cellulose ether ≥ 5%, i-fiber izinga le-ether elonakalisiwe alinakulungiswa. (Kwesinye isikhathi kunamaphutha kule ndlela. Enye ukuthi umenzi ungeze umkhiqizo oqokiwe ofanele ikhasimende elithile ngemuva kokushiya ifektri;

7. Abanye abakhiqizi bahlanganisa inani elincane le-CMC libe yi-hydroxypropylylylylylylylylylylylylylylm methyl celtuleose ether, futhi lapho ikhambi le-cmc emanzi lihlangana tin, isiliva, i-aluminium, ukuhola, ukusabela kwensimbi kanye nokusabela kwemvula kuzokwenzeka; Isixazululo se-CMC esinamanzi kanye ne-calcium lapho, i-magnesium, kanye nosawoti

8. Uma izimo zivuma, zivivinya ngokuqondile ukubonwa kwesisombululo esinamanzi se-cellulose ether bese uqhathanisa izinga lokugcinwa kwamanzi levolumu ye-cellulose mobile.
