Kedu ihe bụ Hydroxypropyl methylcellulose?

1. Okwu mmalite

Hydroxypropyl methylcellulose (HPMC) bụ polymer a na-eji mmiri soluble eme ihe nke sitere na cellulose.Ọ bụ ihe na-abụghị ionic, enweghị isi, enweghị ụtọ, ọcha na ntụ ntụ na-acha ọcha nke a na-ejikarị eme ihe na nri, ọgwụ na ụlọ ọrụ ịchọ mma.HPMC nwere ọtụtụ ngwa, gụnyere ịgba, emulsifying, nkwusioru, nkwụsi ike, na imepụta ihe nkiri.A na-ejikwa ya dị ka ihe nkedo, mmanụ mmanu, na nke na-agbasasị n'imepụta mbadamba nkume na capsules.

2. Akụrụngwa Raw

Isi akụrụngwa eji emepụta HPMC bụ cellulose, nke bụ polysaccharide nke mejupụtara nkeji glucose.Enwere ike nweta cellulose site n'ụdị dị iche iche, gụnyere osisi pulp, owu, na eriri osisi ndị ọzọ.A na-eji usoro kemịkal agwọ cellulose ahụ iji mepụta hydroxypropyl methylcellulose.

3. Usoro nrụpụta

Usoro mmepụta nke HPMC gụnyere ọtụtụ usoro.Nke mbụ, a na-emeso cellulose ahụ na alkali, dị ka sodium hydroxide, iji mepụta cellulose alkali.A na-emezi cellulose alkali a na methyl chloride na propylene oxide iji mepụta hydroxypropyl methylcellulose.A na-asachapụ hydroxypropyl methylcellulose ma kpoo ya ka ọ ghọọ ntụ ntụ ọcha.

4. njikwa mma

Njikwa ogo bụ akụkụ dị mkpa nke usoro nrụpụta nke HPMC.A na-ekpebi ogo ngwaahịa ahụ site na ịdị ọcha nke cellulose, ogo nke nnọchi nke otu hydroxypropyl, na ogo nnọchi nke otu methyl.A na-ekpebi ịdị ọcha nke cellulose site na ịnwale viscosity nke ngwọta, ebe a na-ekpebi ogo nke nnọchi site na ịnwale ogo hydrolysis nke hydroxypropyl methylcellulose.

5. Nkwakọ ngwaahịa

A na-akpakọkarị HPMC na akpa ma ọ bụ drum.A na-ejikarị polyethylene ma ọ bụ polypropylene eme akpa ndị ahụ, ebe a na-ejikarị ígwè ma ọ bụ rọba mee drum.Ekwesịrị ịhọrọ ihe nkwakọ ngwaahịa iji hụ na echekwabara ngwaahịa ahụ site na mmiri na ihe ndị ọzọ gburugburu ebe obibi.

6. Nchekwa

Ekwesịrị ịchekwa HPMC n'ebe dị jụụ, kpọrọ nkụ, pụọ na ìhè anyanwụ kpọmkwem na ebe okpomọkụ ndị ọzọ.Ekwesịrị ichebe ngwaahịa ahụ site na mmiri na ihe ndị ọzọ metụtara gburugburu ebe obibi.

7. Nkwubi okwu

HPMC bụ polymer na-agbaze mmiri nke a na-ejikarị eme ihe nke sitere na cellulose.A na-eji ya na ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ na ụlọ ọrụ ịchọ mma.Usoro mmepụta nke HPMC gụnyere ọtụtụ usoro, gụnyere ọgwụgwọ cellulose na alkali, mmeghachi omume nke cellulose alkali na methyl chloride na propylene oxide, na ịdị ọcha na ihicha nke hydroxypropyl methylcellulose.Njikwa ogo bụ akụkụ dị mkpa nke usoro nrụpụta, yana ngwaahịa kwesịrị ịchekwa ya na ebe dị jụụ, nke kpọrọ nkụ, pụọ na ìhè anyanwụ kpọmkwem na isi mmalite ndị ọzọ nke okpomọkụ.
