1. Gịnị bụ hydroxypropyl methylcellulose?
Hydroxypropyl methylcellulose (HPMC)bụ ihe na-adịghị egbu egbu na nke na-adịghị emerụ ahụ na-abụghị ionic cellulose ether, nke a na-ejikarị eme ihe na ihe owuwu ụlọ, nri, ọgwụ, ihe ịchọ mma na ubi ndị ọzọ. Ọ nwere ọrụ nke ịgbatị, njide mmiri, nhazi ihe nkiri, njikọta, mmanye na nkwusioru, ma nwee ike igbari n'ime mmiri iji mepụta ngwọta viscous na-enweghị atụ ma ọ bụ translucent.
2. A na-ejikarị na ojiji nke HPMC
Ogige ihe owuwu
A na-ejikarị HPMC eme ihe n'ụlọ dịka ngwa ngwa ciment, ntụ ntụ, nrapado tile, wdg.:
Ọrụ: Mee ka arụmọrụ ihe owuwu dịkwuo elu, melite njide mmiri, gbasaa oge na-emeghe, ma melite arụmọrụ njikọ.
Usoro ojiji:
Tinye ozugbo na ngwa agha agwakọta akọrọ, ego a tụrụ aro bụ 0.1% ~ 0.5% nke uka ciment ma ọ bụ mkpụrụ;
Mgbe ịmechara nke ọma, tinye mmiri ma tinye ya na slurry.
Ụlọ ọrụ nri
Enwere ike iji HPMC dị ka thickener, stabilizer na emulsifier, a na-ahụkarị ya na nri dị ka ice cream, jelii, achịcha, wdg.
Ọrụ: meziwanye uto, mee ka usoro ahụ guzosie ike, ma gbochie stratification.
Ojiji:
Na-agbaze na mmiri oyi, a na-edozi usoro ọgwụgwọ a na-atụ aro n'etiti 0.2% na 2% dịka ụdị nri;
Ịkpọ oku ma ọ bụ n'ibu akpasu nwere ike mee ngwangwa mgbasa.
Ụlọ ọrụ ọgwụ
A na-ejikarị HPMC eme ihe na mkpuchi mbadamba ọgwụ, matrix mbadamba ihe na-ahapụ ma ọ bụ shei capsule:
Ọrụ: imepụta ihe nkiri, ntọhapụ ọgwụ na-egbu oge, na nchebe nke ọrụ ọgwụ.
Ojiji:
Kwadebe n'ime ngwọta na ntinye nke 1% ruo 5%;
Fesa nke ọma n'elu mbadamba nkume iji mepụta ihe nkiri dị mkpa.
Ihe ịchọ mma
HPMCA na-eji dị ka thickener, emulsion stabilizer ma ọ bụ onye na-emepụta ihe nkiri, nke a na-ejikarị na ihu ihu, lotions, wdg.:
Ọrụ: Melite udidi ma kwalite mmetụta nke ngwaahịa ahụ.
Ojiji:
Tinye na matriks ịchọ mma nke nha ma kpalie nke ọma;
Usoro onunu ogwu a na-abụkarị 0.1% ruo 1%, gbanwee dabere na ngwaahịa achọrọ.
3. Usoro mgbasa nke HPMC
Mmiri mmiri na-emetụta solubility nke HPMC nke ukwuu:
Ọ dị mfe igbari na mmiri oyi ma nwee ike ịmepụta ngwọta otu;
Ọ bụ insoluble na mmiri ọkụ, ma enwere ike gbasasịa na-etolite a colloid mgbe obi jụrụ.
Usoro mgbasa akọwapụtara:
Wụsa HPMC nwayọọ nwayọọ n'ime mmiri, zere ịwụsa ozugbo iji gbochie caking;
Jiri mkpali na-agwakọta nke ọma;
Gbanwee mkpokọta ngwọta dị ka ọ dị mkpa.
4. Akpachara anya maka iji HPMC
Njikwa onunu ogwu: N'ọnọdụ dị iche iche ngwa, usoro onunu ogwu na-emetụta arụmọrụ ahụ ozugbo ma ọ dị mkpa ka anwale ya dịka mkpa.
Ọnọdụ nchekwa: Ekwesịrị ịchekwa ya na ebe dị jụụ, kpọrọ nkụ, ikuku ikuku iji zere mmiri na okpomọkụ dị elu.
Nchedo gburugburu ebe obibi: HPMC bụ ihe na-emebi emebi, ọ dịghịkwa emetọ gburugburu ebe obibi, mana ọ ka kwesịrị iji ya mee ihe n'ụzọ ziri ezi iji zere ịla n'iyi.
Nnwale ndakọrịta: Mgbe agbakwunyere na sistemu dị mgbagwoju anya (dịka ihe ịchọ mma ma ọ bụ ọgwụ), ekwesịrị ịnwale ndakọrịta na ihe ndị ọzọ.
5. Uru nke HPMC
Na-adịghị egbu egbu, enyi na gburugburu ebe obibi, nchekwa dị elu;
Ọdịiche dị iche iche, na-eme mgbanwe maka ngwa ngwa dị iche iche;
Nkwụsi ike dị mma, nwere ike ichekwa arụmọrụ ruo ogologo oge.
6. Nsogbu nkịtị na ngwọta
Nsogbu Agglomeration: Lezienụ anya na mgbakwunye gbasasịrị n'oge eji wee kpalite nke ọma n'otu oge ahụ.
Ogologo oge mgbasa: Enwere ike iji pretreatment mmiri ọkụ ma ọ bụ mkpagharị igwe mee ngwangwa mgbasa.
Mmebi arụmọrụ: Lezienụ anya na ebe nchekwa nchekwa iji zere mmiri na okpomọkụ.
Site na iji HPMC sayensị na ezi uche, ya multifunctional e ji mara nwere ike n'ụzọ zuru ezu tinye n'ọrụ iji nye elu-edu ngwọta maka iche iche ọrụ.
