Hydroxypyl Methylcellose, chepụta nke a agaghị akwa ụta!

1. A na-ekewa hpmc na ụdị ngwa ngwa

HPMC ngwa ngwa na Folfix S Folz, usoro ihe mmepụta, ka ịgbakwunye ọgwụgwọ glyxal.

Tdị HPMC ozugbo etinyeghị akwụkwọ ozi ọ bụla, dịka "100000" bụ "100000 viscosit na-agbasa HPMC".

2. Na ma ọ bụ na-enweghị s, njirimara dị iche iche

Ngwa ngwa na-agbasa ngwa ngwa, na mmiri oyi na-agbasa ngwa ngwa, na-apụ n'anya na mmiri, n'oge a enweghị ezigbo mmiri, na-eme ka viscosis nke mmiri na-aghọ nnukwu.

Ozugbo hpmc, nwere ike ịgbasa ngwa ngwa na mmiri ọkụ na ihe dị ka afọ 70 ℃, ka a tụfuo ya na ụfọdụ okpomọkụ, viscosit jiri nwayọọ nwayọọ na-egosi, ruo mgbe e guzobere onye na-ahụ anya.

3. Na ma ọ bụ na-enweghị s, ojiji dị iche iche

Enwere ike iji naanị HPMC ozugbo na ntụ ntụ na ngwa agha, na gluu mmiri na agba ma na-asa ya, a gaghị eji ihe oriri, a gaghị eji ya.

Ngwa ngwa a na-asụpụ hpmc, na ngwa ngwa sara mbara, na ntụ ntụ, ngwa agha, mmiri, a na-asa mmiri, ọ nweghị taboo.

4. Tinye cellulose jiri nwayọ na-aga na ụlọ okpomọkụ, na-akpali oge na-aga n'ihu na usoro ahụ ruo mgbe agbanwee ihe ndozi.

Ihe ndị na-emetụta njigide mmiri nke hydropyyl methyl cellulose?

Ngwa ahịa hydroxypypyl methylcelllose HPMC na-emetụtakarị ihe ndị a:

1.

HPMC nke mmeghachi omume, metoxy, hydroxyproporxy Uniformy, ọnụego mmiri dị elu.

2

Ọkụ na-ekpo ọkụ nwere oke okpomọkụ na ọnụego ihu igwe dị elu. Kama nke ahụ, ọnụ ọgụgụ njigide mmiri adịghị ala.

3. HPMC viscosity nke cellulose

Mgbe viscosity nke HPMC na-abawanye, ọnụego mmiri na-abawanye. Mgbe viscssiosity ruru otu ogo, mmụba nke ọnụego njigide mmiri na-adị larịị.

Ego nke cellulose ether HPMC kwukwara

Ọnụ ọgụgụ karịrị nke cellulose eat hpmc gbakwụnyere, dị elu mmiri na-ahụ mmiri, ka mma njigide mmiri.

N'adịghị 0.25-0.6%, ọnụnọ mgbochi mmiri na-abawanye ngwa ngwa na mmụba nke ego mgbakwunye ahụ. Ọnụ ọgụgụ na-abawanye na-egbu egbu mmiri na-egbu oge mgbe egosiri mgbakwunye ego.
