Lekwasị anya na cellulose ethers

Ụdị, ọdịiche na ojiji nke HPMC

HPMC, aha zuru oke bụ Hydroxypropyl Methylcellulose, bụ ether cellulose na-abụghị ionic nke a na-ejikarị arụ ọrụ, ọgwụ, nri, kemịkalụ kwa ụbọchị na mpaghara ndị ọzọ.

1. Nhazi site na viscosity

The viscosity nke HPMC bụ otu n'ime ya mkpa anụ ahụ Njirimara, na HPMC nwere dị iche iche viscosities nwere nnukwu ọdịiche na ngwa. Ogologo viscosity sitere na viscosity dị ala (iriri nke cps) ruo elu viscosity (iri puku kwuru iri puku cps).

HPMC viscosity dị ala: A na-ejikarị ngwa na-achọ mgbasa ngwa ngwa ma ọ bụ ịgbasa, dị ka nkwusioru ọgwụ mmiri mmiri, sprays, wdg.

Ọkara viscosity HPMC: ọtụtụ-eji kwa ụbọchị kemịkalụ, dị ka ncha ntutu, ịsa gel, wdg, na-enye agafeghị oke ndim mmetụta na ezi rheological Njirimara.

HPMC viscosity dị elu: a na-ejikarị ya eme ihe na-ewu ụlọ, dị ka ngwa agha akọrọ, nrapado tile seramiiki, ime ime na mputa mgbidi, wdg, na-enye ezigbo mkpụkọ, njigide mmiri na ihe owuwu.

2. Nhazi site na ogo nke nnọchi

Ogo nke nnọchi nke HPMC na-ezo aka ọnụ ọgụgụ nke hydroxypropyl na methyl nnọchi n'ime molekul ya, nke a na-egosipụtakarị dị ka MS (ogo nke nnọchi hydroxypropyl) na DS (methyl nnọchi).

Obere ogo nke nnọchi HPMC: agbaze ngwa ngwa ma a na-ejikarị ya na ngwa na-achọ mgbasa ngwa ngwa, dị ka mkpuchi mbadamba ọgwụ na ihe ọ drinksụ drinksụ ozugbo.

Ọkwa dị elu nke nnọchi HPMC: Ọ nwere viscosity dị elu na njigide mmiri ka mma, ọ dịkwa mma maka ngwaahịa ndị chọrọ viscosity dị elu na njigide mmiri dị elu, dị ka ihe owuwu ụlọ na ihe ịchọ mma na-ekpo ọkụ nke ukwuu.

3. Nhazi site na mpaghara ngwa

Ojiji a kapịrị ọnụ nke HPMC na mpaghara dị iche iche dịgasị iche iche, enwere ike kewaa ya n'ụdị ndị a dịka mpaghara ngwa:

ihe owuwu ụlọ

Isi ọrụ HPMC na mpaghara ihe owuwu bụ imeziwanye arụmọrụ ihe owuwu na ịdịte aka nke ihe, gụnyere:

Ngwa ngwa akọrọ: HPMC na-enye njigide mmiri dị mma, mmanye na ịrụ ọrụ, na-eme ka nrụpụta ihe owuwu na-arụ ọrụ yana mma ngwaahịa.

Ihe nrapado taịlị: Mee ka ike njikọta na ihe mgbochi mwepu iji hụ na nkwụsi ike na ịdịte aka nke paving tile.

Agba na putty: Mee ka rheology na njigide mmiri nke agba na putty iji gbochie mgbawa na nkwụsị ntụ.

ọgwụ

N'ebe a na-emepụta ọgwụ, a na-ejikarị HPMC eme ihe dị ka ihe ndị na-emepụta ọgwụ, gụnyere:

Mbadamba ụrọ: Dị ka ihe mkpuchi mbadamba nkume, ọ na-enye ihe akaebe nke mmiri, solubilization na ọrụ nkwụsịtụ iji meziwanye nkwụsi ike na ọdịdị nke ọgwụ.

Gel: eji akwadebe gels ọgwụ, na-enye ezigbo adhesion na biocompatibility.

nri

A na-eji HPMC eme ihe dị ka thickener, emulsifier na stabilizer na ụlọ ọrụ nri, gụnyere:

Ngwaahịa noodle: Na-abawanye ike na ngbanwe nke mgwakota agwa, melite uto na udidi.

Ngwaahịa ara ehi: Dị ka emulsifier na stabilizer, ọ na-egbochi stratification na mmiri ozuzo nke mmiri ara ehi ngwaahịa na mma ngwaahịa kwụsie ike.

Kemikal kwa ụbọchị

N'ime kemịkalụ kwa ụbọchị, a na-eji HPMC eme ihe dị ka ndị na-agbapụta ihe na ihe nkwusi ike, gụnyere:

Shampoo na mmiri ịsa ahụ: Nye viscosity na rheology na-agafeghị oke iji meziwanye ahụmịhe iji ngwaahịa.

Ngwaahịa na-ahụ maka akpụkpọ ahụ: Dị ka ihe na-agbapụta na mmiri ara ehi, ọ na-eme ka mmetụta moisturize na ahụmahụ ojiji nke ngwaahịa ahụ dịkwuo elu.

4. Ebumnuche ndị ọzọ pụrụ iche

A pụkwara iji HPMC mee ihe n'ubi pụrụ iche, dị ka ngwupụta mmanụ, ụlọ ọrụ seramiiki, ụlọ ọrụ akwụkwọ, wdg.

Mmepụta Oilfield: A na-eji mmiri na-egwupụta mmiri na mmiri na-agbaji iji nye ezigbo mbelata na mbelata mmiri mmiri.

Ụlọ ọrụ seramiiki: ejiri ya dị ka onye na-ekekọta na nkwụsịtụ iji melite nkwụsi ike na mmiri mmiri nke seramiiki slurry.

Ụlọ ọrụ na-emepụta akwụkwọ: ejiri mee ihe maka ọgwụgwọ elu nke akwụkwọ iji mee ka ike ya na mmiri na-eguzogide ya.

Dị ka a multifunctional cellulose mmepụta, HPMC nwere magburu onwe anụ ahụ na chemical Njirimara na sara mbara ngwa atụmanya. Ụdị HPMC dị iche iche nwere njirimara nke ha n'ihe gbasara viscosity, ogo nke nnọchi na ojiji. Ịhọrọ ụdị HPMC kwesịrị ekwesị dabere na ngwa achọrọ nwere ike imeziwanye arụmọrụ na ịdịmma ngwaahịa. Site na ọganihu nke sayensị na nkà na ụzụ na mgbasawanye nke ngwa ngwa, ngwa nke HPMC ga-aba ụba na omimi.
