Kuvuga kuri HydroxyPropyl Methyl Cellulose (HPMC)

1. Alias ​​ya HydroxyPropyl Methylcellse?

--SANG: HYDROXYPropyl Methyl Methyl MethyPropyl Methyl Methyl Methyl Methyl Methyl Methyl Methyl Methyl Methyl Methyl Methyl Methyl Methyli: HPMC cyangwa MHPC alias: HYPPROMOSE; Ubugari bwa CellroxyPropyl Methyl ether; HYPROMMOMELLOSE, TOLLULULOSE, 2-HYDROXYPropylmethylmethyl selile. Ubugari bwa CellroxyPropyl Methyl Ether Ether Syplose.

2. Ni ubuhe buryo bukoreshwa na hydroxyproppopyl methylcellse (HPMC)?

. HPMC irashobora kugabanywamo urwego rwubwubatsi, amanota yibiribwa hamwe nicyiciro cya farumasi ukurikije intego. Kugeza ubu, ibyinshi mu bicuruzwa byo mu rugo ni urwego rwo kubaka. Mu rwego rwo kubaka, ifu ya Prowty ikoreshwa mu mubare munini, hafi 90% ikoreshwa kuri Prowder ifu, kandi ahasigaye hakoreshwa kuri sima na kole.

3. Hariho ubwoko bwinshi bwa hydroxyproppopyl methylcellse (HPMC), kandi ni irihe tandukaniro rifite?

- Amafaranga: HPMC irashobora kugabanywamo ubwoko bwa ako kanya no muburyo bushyushye. Ubwoko bwibicuruzwa ako kanya amarushanwa vuba mumazi akonje arazimira mumazi. Muri iki gihe, amazi adafite ubuyobe kuko HPMC yatatanye gusa mumazi gusa nta guseswa nyabyo. Hafi yiminota 2, viscosiya yabanyamanswa buhoro buhoro, gukora virusi yacyo. Ibicuruzwa bishyushye, iyo byujuje amazi akonje, birashobora gutatana vuba mumazi ashyushye kandi ukabura mumazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, viscosity igaragara buhoro kugeza igihe ikora virusi iterana. Ubwoko bushyushye buke burashobora gukoreshwa gusa muri pattle ifu na minisiteri. Mu mazi no gusiga irangi, hazabaho ibintu byinjizamo ibintu kandi ntibishobora gukoreshwa. Ubwoko bwihuse bufite uburyo bwagutse bwa porogaramu. Irashobora gukoreshwa mubukonje na minisiteri, kimwe na kole yamazi kandi irangi, nta binyuranye.

4. Nigute wahitamo hydroxyproppopyl methylcellse (HPMC) kumigambi itandukanye?

--Umutekano :: Gushyira mu bikorwa ifu ya Putty: Ibisabwa birasa, kandi viscosity ni 100.000, birahagije. Icyangombwa nugumana neza amazi. Gushyira mu bikorwa minisiteri: Ibisabwa byinshi, viscosity, 150.000 nibyiza. Gusaba kole: Ibicuruzwa ako kanya hamwe nisuka nyinshi zirakenewe.

5. Ni iki kigomba kwitabwaho muburyo bwo gushyira mubikorwa isano iri hagati ya viscosity nubushyuhe bwa HPMC?

- Gusubiramo: Guscosity ya HPMC nibipimo bidafite ubushyuhe, ni ukuvuga, viscosity yiyongera uko ubushyuhe bugabanuka. Ibyatsi bibi mubisanzwe bivuga bivuga ibisubizo byikizamini cya 2% yamazeko ku bushyuhe bwa dogere 20.

Mubyiciro bifatika, twakagombye kumenya ko mubice bifite ubushyuhe bunini hagati yizuba nimbeho, birasabwa gukoresha ubushyuhe buke ugereranije nimbeho, bikubera byiza kubaka. Bitabaye ibyo, igihe ubushyuhe ari buke, vino ya selile iziyongera, kandi ikiganza cyumva kizaremereye mugihe gihumura.

Hagati Hagati: 75000-100000 ikoreshwa cyane kubashizwemo

Impamvu: Kugumana amazi meza

Bescosity yo hejuru: 150000-200000 ikoreshwa cyane kumashusho yubushyuhe bwa polystyrene ifu ya rubanda ya rubrmal na minisiteri ya microbead.

Impamvu: Ibyatsi ni byinshi, minisiteri ntabwo yoroshye kugwa, sag, kandi kubaka biratera imbere.

6. Hpmc ni selile itari ionic ether, none niki kitari ionic?

- Muri rusange: Mu magambo ya Palaman, ntabwo ari ions ni ibintu bidakora ionize mumazi. Ionation ivuga inzira aho hatangwamo amashanyarazi yitandukanije na ™ iyoni ishobora kugenda muburyo bwihariye (nk'amazi, inzoga). Kurugero, sodium chloride (nacl), umunyu turya burimunsi, turasenyutse mumazi na ON +) ni ions yuzuye na chloride iny. Nukuvuga, igihe HPMC yashyizwe mumazi, ntabwo izatandukanya ions, ariko ibaho muburyo bwa molekile.
