▲Hydroxypropyl methyl seluplose (hpmc)yi-odortight, engenakuthelekiswa ne-powder emhlophe engenabungozi. Emva kokunyibilikisa ngokupheleleyo emanzini, i-Hydroxypropyl Methyl Selelose iya kwenza i-collous engabonakaliyo.
Izinto eziphambili ze-HydroxyPOpyl Methyl Selelose (HPMC): I-HPMC ye-HPMC, i-propylene oxide, i-propylene oxide, i-supprelic, i-toone, i-iyopropanol, njl.
Thelekisa izibonelelo kunye nezinto ezingalunganga ze-hydroxypropyl methyl sellyulose:
1.Ukugcina i-HydroxylyPlyl Methyl Selelose HPMC ukhululekile kwaye uxinezelekile kakhulu, kunye ne-0.3-0.4 / ml.
I-HPMCTECRECTIONCE inolwelo oluhle kakhulu kwaye ivakalelwa nzima, ehluke kakhulu kwimveliso yokwenene ngembonakalo.
2.Umgaqo-nkqubo we-hydroxyl methyl seluplose hpmc i-hpmc aqueus icacile, ukuhambisa okuphezulu kokukhanya, ireyithi yokugcina amanzi> 97%.
Isisombululo se-HPMC esikhutshiwe i-HPMC esimdaka, kwaye izinga lokugcina amanzi kunzima ukufikelela kwi-80%.
3.Ukugcina i-HPMC akufuneki ivumba le-ammonia, isitatshi kunye notywala.
I-HPMCRECTIONCE inokuthi idla ngokuncwina zonke iintlobo zeencasa, nokuba ayinantsingiselo, iya kuziva inzima.
4.Ukugcina i-HydroxylDollipyl Methyl Selelose HPMC POFMPER yi-fibrod i-fibrod phantsi kwe-microscope okanye iglasi yokukhulisa.
I-HPMCRECTIONCTURTEDC inokubonwa njengezinyibilikisi zegralini okanye amakristali phantsi kwe-microscope okanye iglasi yokukhulisa.
Yeyiphi imiba echonge izibonelelo kunye nezinto eziluncedo kwi-hydroxypropy ye-methyl sellise?
I-1.White degree
Nangona ubumhlophe abunakufumanisa ukuba i-HPMC kulula ukuyisebenzisa, kwaye ukuba iiarhente zomhlophe zongezwa ngexesha lenkqubo yemveliso, iya kuchaphazela umgangatho wayo. Nangona kunjalo, uninzi lweemveliso ezilungileyo lube mhlophe mhlophe.
2.Ukunengxaki
Ukulunga kwe-HPMC ngokubanzi kune-80 Mesh kunye ne-100 Mesh, kwaye kuhle ukulunga, ngokubanzi, ngcono.
3.Transtimtance
Fakahydroxypropyl methyl seluplose (hpmc)emanzini ukwenza i-colloid ebonakalayo, kwaye ujonge ukukhanya kwayo. Ukuphakama okuphezulu kokudlulisela, okungcono, kubonisa ukuba kukho izinto ezingafakwanga kuzo kuyo. Ukufakwa kweesanda ezithe nkqo zihlala zilungile, ngelixa ezona zinto zivuthiweyo zimbi kakhulu.
I-Squlelo
Inkulumbuso ekhethekileyo, enzima kakhulu. Ubungqina bukhulu, ngokubanzi ngenxa yokuba umxholo weqela le-hydroxypropy kuyo kuphezulu, kwaye umxholo weqela le-hydroxypropy iphezulu, ukugcinwa kwamanzi kungcono.
