▲Hydroxypropyl methyl cellulose (HPMC)farin foda ne mara wari, mara daɗi, mara guba. Bayan cikar narkewa cikin ruwa, hydroxypropyl methyl cellulose zai samar da colloid danko mai haske.
▲ Babban albarkatun kasa na hydroxypropyl methyl cellulose (HPMC): mai ladabi auduga, methyl chloride, propylene oxide, da sauran albarkatun kasa, caustic soda, acid, toluene, isopropanol, da dai sauransu.
Kwatanta fa'idodi da rashin amfani na hydroxypropyl methyl cellulose:
1.Pure hydroxypropyl methyl cellulose HPMC yana da sako-sako da gani kuma yana da ƙananan ƙananan yawa, tare da sikelin 0.3-0.4 / ml.
HPMC da aka lalata tana da ruwa mai kyau sosai kuma yana jin nauyi, wanda ya bambanta da ainihin samfurin a bayyanar.
2.Pure hydroxypropyl methyl cellulose HPMC ruwa bayani a fili yake, babban haske watsa, ruwa riƙe kudi> 97%.
Maganin ruwan ruwa na HPMC da aka lalata yana da datti, kuma yawan riƙe ruwa yana da wahala a kai 80%.
3.Pure HPMC kada kamshin ammonia, sitaci da alcohols.
HPMC da aka yi zina yawanci tana iya kamshin kowane irin dandano, ko da ba ta da ɗanɗano, za ta ji nauyi.
4.Pure hydroxypropyl methyl cellulose HPMC foda ne fibrous a karkashin wani microscope ko girma gilashi.
Ana iya kiyaye HPMC da aka lalata azaman daskararrun granular ko lu'ulu'u a ƙarƙashin na'urar hangen nesa ko gilashin ƙara girma.
Daga wadanne al'amura don gano fa'idodi da rashin amfani na hydroxypropyl methyl cellulose?
1.fararen digiri
Ko da yake fari ba zai iya tantance ko HPMC yana da sauƙin amfani ba, kuma idan an ƙara kayan aikin fata yayin aikin samarwa, zai shafi ingancinsa. Duk da haka, yawancin samfurori masu kyau suna da fari mai kyau.
2.Lafiya
Mafi kyawun HPMC gabaɗaya yana da raga 80 da raga 100, kuma mafi kyawun ingancin, gabaɗaya magana, mafi kyau.
3.Transmittance
Sakahydroxypropyl methyl cellulose (HPMC)a cikin ruwa don samar da colloid mai haske, da kuma duba haskensa. Mafi girman watsawar haske, mafi kyau, yana nuna cewa akwai ƙananan abubuwa marasa narkewa a ciki. The permeability na tsaye reactors ne kullum mai kyau, yayin da na kwance reactors ne mafi muni.
4.Kasuwanci
Girman ƙayyadaddun nauyi, mafi nauyi mafi kyau. Ƙayyadaddun ƙayyadaddun yana da girma, gabaɗaya saboda abun ciki na ƙungiyar hydroxypropyl a ciki yana da girma, kuma abun ciki na ƙungiyar hydroxypropyl yana da girma, riƙewar ruwa ya fi kyau.
