Hydroxypylththththththylcelllose (hpmc)

Hydroxypyl Methylcellose (HPMC), nke a makwaara dị ka hymerler site na polmer na-enweta site na cellose. A na-ejikarị ya n'ụlọ ọrụ dị iche iche maka ihe ndị pụrụ iche, gụnyere ọgwụ, owuwu, ihe oriri, ihe ịchọ mma na nlekọta onwe onye. Na ntuziaka a zuru oke, anyị ga-enyocha usoro kemịkalụ, Njirimara, usoro imepụta ihe, ngwa, na uru nke HPMC n'ụzọ zuru ezu.

1. Okwu Mmalite na HPMC:

Hydroxypyl Methylcellose (HPMC) bụ nke na-abụghị nke ikuku sel sel sellulose site na ndozi mmiri. Ọ bụ usoro celligose na propylene oxide na methyl chloride iji webata ndị dị n'otu na methyl na Bellone Backbone. Ihe ngosi nke polymer na-egosiputa otutu ihe na-eme ka ọ baa uru bara ezigbo uru na ngwa usoro ọmụmụ dị iche iche.

2. Ihe owuwu kemịkalụ na akụrụngwa:

A na-eji HPMC mara ihe owuwu kemịkalụ ya, nke mejupụtara okirikiri sellose na hydroxypyl na methyl na methyl jikọtara ọnụ na ìgwè hydroxy. Oru nke nbanye (DS) nke Hydropyyl na Methyl nwere ike ịdị iche, nke na-ebute akara akara dị iche iche nke HPMC na njiri mara dị ka ụdị viscosity, solubality, na omume gelesh.

Njirimara nke HPMC na-emetụta ihe ndị dị ka oke molecular, ogo nke nnọchi anya, na hydroxylyl /thylpyl /thylpyl /thyl. Na mkpokọta, HPMC gosipụtara ihe ngosi igodo ndị a:

  • Mmiri-soludity
  • Ike film
  • Njirimara na ihe ndị na-eme mkpọtụ
  • Elu ọrụ
  • Kwụsie ike na mbara igwe
  • Ndakọrịta na ihe ndị ọzọ

3. Usoro ịkpata:

Mmepụta HPMC gụnyere ọtụtụ usoro, gụnyere:

  1. Nkwadebe nke cellulose: na-eji cellulose, na-ejikarị ya na osisi ma ọ bụ owu mee ya, a na-asacha ma nụchaa iwepu adịghị ọcha na lignin.
  2. Mmeghachi omume eality: cellylene oxide na methylch chloride na ọnụnọ Alkali na-echeta hydypPropyyl na methyl na Belllose Backbone.
  3. Nnọpụ ya na ịsacha: Ngwaahịa a na-esiteghị na-ewepụ ya iji wepu Alkali ma sachaa ngwaahịa na adịghị ọcha.
  4. Ihicha ma ghee: HPMC dị ọcha na-akpọnwụ ma banye n'ime ntụ ntụ kwesịrị ekwesị maka ngwa dị iche iche.

4. Gradges na nkọwapụta:

HPMC dị na ogo akara ule na nkọwapụta iji mezuo ihe ndị a kapịrị ọnụ nke ụlọ ọrụ na ngwa dị iche iche. Ndị a gụnyere ọdịiche na viscosity, ogo ya, ogo nke nnọchi anya, na okpomọkụ gelendation. Ihe nzere nke HPMC gụnyere:

  • Usoro akara ngosi pụrụ iche (dịka, 4000 CPS, 6000 CPS)
  • Akara ngosi dị elu (dịka, 15000 CPS, 20000 CPS)
  • Akara ngosi dị ala (dịka, 1000 CPS, 2000 CPS)
  • Akara mmụta pụrụ iche maka ngwa ndị akọwapụtara (dịka ọmụmaatụ, weghaara ya)

5. Ngwa nke HPMC:

HPMC na-ahụ iji usoro dị iche iche rụọ ọrụ n'ọtụtụ ụlọ ọrụ n'ihi ihe akụrụngwa ya na ndakọrịta dị iche iche. Offọdụ n'ime ngwa dị mkpa nke HPMC gụnyere:

a. Industrylọ ọrụ ọgwụ:

  • Mbadamba ụrọ na okpu mkpuchi
  • Nchịkwa nchịkọta
  • Binders na ndị na-emebi ihe na mbadamba
  • Ihe ngwọta Ophthalmic na nkwụsị
  • Ebumnuche dị ka ude na mmanụ

b. Industrylọ ọrụ owuwu:

  • Ngwaọrụ na ngwaahịa Gypsum (dịka, ogbunigwe, plasters)
  • Talesives na grouts
  • Nkpuchi na usoro na-emecha (EIFS)
  • Ogige na-enweghị atụ
  • Eseresides na mkpuchi mmiri

c. Industrylọ ọrụ nri:

  • Ndị na-eme mkpọtụ ma kwụsie ike na ngwaahịa nri
  • Emulsifier na nkwụsị ụgwọ na saces na akwa
  • Ntuziaka eriri nri
  • Glutan-Baak Bruce na Nchịkọta

d. Nlekọta onwe onye na ihe ịchọ mma:

  • Oke ma na-achụpụ onwe gị na ude na ude
  • Ihe nkiri na fim nke mbụ na ngwaahịa nlekọta ntutu
  • Nchịkwa na-achịkwa na skịlị
  • Anya mmiri na kọntaktị ihu

6. Uru nke iji HPMC:

Ojiji HPMC na-enye ọtụtụ uru gafee ụlọ ọrụ dị iche iche:

  • Arụmọrụ ngwaahịa dị mma na mma
  • Nwelite na ngbanye usoro na nkwụsi ike
  • Ndụ na-ebilite ndụ ma belata mbibi
  • Nrụpụta arụmọrụ na arụmọrụ
  • Ntinye uche na usoro nhazi na ụkpụrụ nchekwa
  • Gburugburu ebe obibi na biocompimepu

7. Usoro na Outlookment:

A na-atụ anya na achọrọ HPMC ahụ ga-aga n'ihu na-eto, na-ebugharị ndị na-abawanye nsogbu, mmepe akụrụngwa, na-achọ maka ọgwụ na ngwaahịa nlekọta ọgwụ. Nnyocha nyocha na mgbalị iche iche na-elekwasị anya na nhazi HPMC, na-agbasa ngwa ya, na imezi usoro iji gboo mkpa ahịa ahịa.

8. Mmechi:

Hydroxypyl Methylcelllose (HPMC) bụ polymer dị iche iche na ngwa dị iche iche n'ofe ọtụtụ ọrụ ụlọ ọrụ. Ngwongwo pụrụ iche ya, dị ka mmiri na-enye ike mmiri, na-eme ihe nkiri, na-eme ka ọ dị oke ọnụ ahịa na ọgwụ, ihe owuwu, nlekọta onwe onye, ​​na ịchọ mma. Dịka otu teknụzụ na ahịa ihe na-achọ ibute, HPMC na-arụ ọrụ dị mkpa na-akpụzi ọdịnihu nke ụlọ ọrụ dị iche iche.
