Hydroxypropylmethylcellulose (HPMC) bụ polymer na-agbanwe agbanwe na nke nwere ike ịbụ nke ezinụlọ cellulose ether.A na-emepụta ya site na usoro mmeghachi omume kemịkalụ site n'ịgbanwe cellulose eke, bụ isi akụkụ nke mgbidi cell osisi.HPMC si na ya pụta nwere ihe pụrụ iche nke na-eme ka ọ baa uru n'ofe ụlọ ọrụ.
1. Chemical Ọdịdị na mejupụtara:
A na-enweta HPMC site na cellulose, nke mejupụtara nkeji glucose ugboro ugboro jikọtara ya na njikọ β-1,4-glycosidic.Site na mgbanwe kemịkalụ, hydroxypropyl na otu methoxy na-ewebata n'ime ọkpụkpụ azụ cellulose.Ogo nke nnọchi (DS) nke hydroxypropyl na methoxy dị iche iche nwere ike ịdị iche, na-ebute akara ule dị iche iche nke HPMC nwere ihe dị iche iche.
Usoro kemịkalụ nke HPMC na-enye ya ike na-emepụta ike na gel, na-eme ka ọ baa uru n'ọtụtụ ngwa dị iche iche n'ofe ụlọ ọrụ dị iche iche.
2. Solubility na rheological Njirimara:
Otu n'ime ihe ndị pụtara ìhè nke HPMC bụ solubility ya na mmiri, na-eme ka ọ bụrụ polymer soluble mmiri.HPMC na-etolite ngwọta doro anya na viscous mgbe etisasịwo na mmiri, na rheological Njirimara nwere ike gbanwee site na-agbanwe molekụla arọ na ogo nke nnọchi.Nke a na-agbanwe agbanwe na rheology na-eme ka HPMC dabara maka ngwa dị iche iche.
3. Ịrụ ihe nkiri:
HPMC nwere ọmarịcha ihe na-emepụta ihe nkiri ma nwee ike ịmepụta ihe nkiri na-agbanwe agbanwe mgbe agbazere polymer na mmiri.Ngwongwo a na-achọta ngwa n'ime ụlọ ọrụ ọgwụ na nri maka mbadamba ihe mkpuchi, na-eme ka ekpomeekpo na-enye ihe mgbochi na ihe nkiri oriri.
4. Ngwa ahụike:
A na-ejikarị HPMC eme ihe na ụlọ ọrụ ọgwụ n'ihi njirimara multifunctional ya.A na-eji ya n'ụdị mbadamba nkume dị ka ihe nkedo, ihe na-agbasa, onye na-emepụta ihe nkiri na onye na-ahapụ ya.Ikike polymer iji chịkwaa ntọhapụ ọgwụ na melite nkwụsi ike nke usoro ọgwụ na-eme ka ọ bụrụ ihe dị mkpa na mmepụta nke ụdị usoro onunu dị iche iche.
5. Ụlọ ọrụ ihe owuwu:
N'ime ụlọ ọrụ na-ewu ụlọ, a na-eji HPMC eme ihe dị ka ihe na-eme ka ọ dị arọ, onye na-ejigide mmiri na onye na-arụ ọrụ na-arụ ọrụ na ngwaahịa simenti dị ka ngwa agha, grouts na plasters.Njirimara rheological ya na-enyere aka melite arụmọrụ, sag resistance na adhesion, na-eme ka ọ bụrụ ihe mgbakwunye isi na ihe owuwu ụlọ.
6. Nri na ihe ịchọ mma:
N'ụlọ ọrụ nri, a na-eji HPMC eme ihe dị ka ihe na-eku ume, emulsifier, na stabilizer n'ụdị ngwaahịa dị iche iche, gụnyere sauces, condiments, na ngwaahịa mmiri ara ehi.Ọdịdị ya na-adịghị egbu egbu na ikike ịmepụta gels doro anya na-eme ka ọ dị mma maka ngwa nri.
N'otu aka ahụ, n'ụlọ ọrụ ịchọ mma, a na-eji HPMC eme ihe n'ụdị dị ka ude, lotions, na shampoos n'ihi na ọ na-agbaze, na-eme ka ọ dị ike, na-emepụta ihe nkiri.Ọ na-enye aka na udidi, viscosity na nkwụsi ike nke ihe ịchọ mma.
7. Agba na mkpuchi:
A na-eji HPMC eme ihe dị ka thickener na rheology modifier na agba na mkpuchi mmiri.Ọ na-eme ka njirimara ngwa nke mkpuchi ahụ dịkwuo mma, dị ka paintability na nkwụsi ike, ma na-eme ka arụmọrụ nke mkpuchi ahụ dịkwuo mma.
8. Nrapado:
N'ime usoro nrapado, HPMC na-arụ ọrụ dị ka onye na-ebu ibu na onye na-ejigide mmiri.Ikike ya iji chịkwaa viscosity na melite adhesion na-eme ka ọ bụrụ ihe bara uru na mmepụta nke adhesives na ụlọ ọrụ dị iche iche, gụnyere osisi na njikọ akwụkwọ.
9. Sistemụ ntọhapụ a na-achịkwa:
Ntọhapụ a na-achịkwa nke ihe ndị na-arụ ọrụ dị oke mkpa nye ọtụtụ ụlọ ọrụ, gụnyere ọgwụ na ọrụ ugbo.A na-ejikarị HPMC chepụta usoro ntọhapụ a na-achịkwa n'ihi ike ya ịmepụta matriks nke na-achịkwa ọnụego ntọhapụ nke ihe mkpuchi ahụ ka oge na-aga.
10. Ngwa biomedical:
N'ihe gbasara biomedicine na injinia anụ ahụ, enyochala HPMC maka ndakọrịta ya na ikike imepụta hydrogels.Enwere ike iji hydrogels ndị a na nnyefe ọgwụ, ọgwụgwọ ọnya, na ngwa mmeghari anụ ahụ.
11. Njirimara nchekwa gburugburu:
A na-ewere HPMC dị ka enyi na enyi gburugburu ebe obibi n'ihi na ọ na-enweta ya site na akụ ndị a na-emegharịgharị ma bụrụkwa ihe na-emebi emebi.Ojiji ya n'ụdị ngwa dị iche iche dabara na ọchịchọ na-eto eto maka ihe na-adịgide adịgide na gburugburu ebe obibi.
12. Ihe ịma aka na echiche:
Ọ bụ ezie na a na-eji HPMC eme ihe n'ọtụtụ ebe, ọtụtụ ihe ịma aka dị, gụnyere mmetụta ya na okpomọkụ, nke na-emetụta njirimara gel ya.Na mgbakwunye, usoro mwepu na mgbanwe kemịkalụ nke cellulose chọrọ nlebara anya nke ọma site n'echiche gburugburu ebe obibi na nkwado.
13. Nrube isi n'usoro iwu:
Dị ka ọ dị n'ihe ọ bụla a na-eji na ọgwụ, nri na ngwaahịa ndị ọzọ na-azụ ahịa, ọ dị oke mkpa na a na-agbaso ụkpụrụ ndị ụlọ ọrụ nhazi setịpụrụ.HPMC na-ezute usoro iwu chọrọ, mana ndị nrụpụta ga-ahụrịrị na nnabata na ntuziaka akọwapụtara maka ngwa ọ bụla.
na ngwụcha:
Hydroxypropylmethylcellulose (HPMC) bụ polymer vasatail nwere ọtụtụ ngwa n'ofe ụlọ ọrụ dị iche iche.Ngwakọta ya pụrụ iche nke solubility, ihe na-emepụta ihe nkiri na njikwa rheology na-eme ka ọ dị mkpa na ọgwụ, ihe owuwu, nri, ihe ịchọ mma, agba, nrapado na ndị ọzọ.Ka ụlọ ọrụ na-aga n'ihu na-achọ ngwọta na-adigide ma dị irè, HPMC nwere ike ịnọgide na-abụ isi ihe na-emepụta ngwaahịa dị iche iche.N'agbanyeghị nsogbu ụfọdụ, nyocha na-aga n'ihu na ọganihu na kemịl cellulose nwere ike gbasaa ngwa ngwa ma melite arụmọrụ nke HPMC n'ọdịnihu.
