4 Basic Production Teknụzụ na usoro nke HPMC, anaghị efu!

Hydroxypropyl methylcellulose (HPMC) bụ polymer vasatail nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche, gụnyere ihe owuwu, ụlọ ọrụ ọgwụ na nri.A na-emepụta HPMC site na iji teknụzụ mmepụta dị iche iche na usoro, dabere na ngwa a chọrọ.N'isiokwu a, anyị ga-enyocha teknụzụ mmepụta ihe anọ na usoro nke HPMC nke ị na-ekwesịghị ileghara anya.

1. Teknụzụ etherification Teknụzụ etherification bụ teknụzụ mmepụta ihe a na-ejikarị maka HPMC.N'ime usoro a, a na-eji alkali agwọ cellulose, dị ka sodium hydroxide, iji mepụta cellulose alkali.A na-eji propylene oxide na methyl chloride meghachi omume na cellulose alkali iji mepụta HPMC.Enwere ike ịchịkwa ogo ngbanwe (DS) nke HPMC site n'ịgbanwe nha nke propylene oxide na methyl chloride n'oge mmeghachi omume ahụ.

Usoro maka HPMC emepụtara site na iji teknụzụ etherification bụ:

Cellulose + Alkali → Alkali Cellulose Alkali Cellulose + Propylene Oxide + Methyl Chloride → HPMC

2. Teknụzụ ịgbasa ịgbasa teknụzụ ịgbasa bụ teknụzụ mmepụta dị elu karịa maka HPMC.N'ime usoro a, a na-agbaze cellulose na ngwọta alkali wee meghachi omume na propylene oxide na methyl chloride.A na-efesa ihe ngwọta HPMC nke si na ya pụta bụ nke a mịrị amị iji mepụta ntụ ntụ HPMC.

Usoro maka HPMC emepụtara site na iji teknụzụ ihicha mmiri bụ:

Cellulose + Alkali → Alkali Cellulose Alkali Cellulose + Propylene Oxide + Methyl Chloride → HPMC Ngwọta HPMC Ngwọta + ịgbasa nkụ → HPMC ntụ ntụ

3. Nkà na ụzụ nkwusioru Polymerization teknụzụ nkwusioru polymerization bụ teknụzụ mmepụta ọzọ maka HPMC.N'ime usoro a, a na-akwụsị cellulose n'ime ihe mgbaze wee meghachi omume na propylene oxide na methyl chloride n'ihu onye nrụpụta polymerization iji mepụta HPMC.

Usoro maka HPMC emepụtara site na iji teknụzụ nkwusioru polymerization bụ:

Cellulose + Ihe mgbaze + Polymerization Onye mmalite → Cellulose nkwusioru Cellulose nkwusioru + Propylene Oxide + Methyl Chloride → HPMC

4. Ngwọta Polymerization Teknụzụ ngwọta polymerization teknụzụ bụ teknụzụ mmepụta ọhụrụ maka HPMC.N'ime usoro a, a na-agbaze cellulose na ihe mgbaze wee meghachi omume na propylene oxide na methyl chloride n'ihu onye nrụpụta polymerization iji mepụta HPMC.

Usoro maka HPMC emepụtara site na iji teknụzụ polymerization ngwọta bụ:

Cellulose + Ihe mgbaze + Polymerization Initiator → Cellulose Solution Cellulose Solution + Propylene Oxide + Methyl Chloride → HPMC

N'ikpeazụ, HPMC bụ polymer dị iche iche nke a na-emepụta site na iji teknụzụ mmepụta dị iche iche na usoro, dabere na ngwa a chọrọ.Teknụzụ mmepụta ihe anọ na usoro nke HPMC gụnyere teknụzụ etherification, teknụzụ ihicha ịgba, teknụzụ polymerization nkwusioru, na teknụzụ polymerization ngwọta.Ịghọta teknụzụ mmepụta na usoro nke HPMC nwere ike inyere ndị na-emepụta aka ịhọrọ ngwaahịa HPMC ziri ezi maka ngwa ha kpọmkwem.
