Kedu ihe bụ ojiji nke hydroxypropyl methylcellulose?

Hydroxypropyl methylcellulose (HPMC) bụ ether cellulose na-abụghị ionic nke nwere ọtụtụ ọrụ yana ngwa dị iche iche.

1. Ihe owuwu ụlọ

N'ime ụlọ ọrụ ihe owuwu, a na-eji HPMC eme ihe n'ọtụtụ ebe na ngwaahịa ndị dị ka ngwa ngwa ciment, ihe ndị dabeere na gypsum, uzuzu putty na nrapado tile. Isi ọrụ ya gụnyere:

Njide mmiri: HPMC nwere ike melite njide mmiri nke ngwa ngwa ma gbochie mmiri ịpụpụ ngwa ngwa, si otú a na-emeziwanye arụmọrụ ihe owuwu yana ọgwụgwọ.

Ịba ụba na mmanu mmanu: Ọ nwere ike ịbawanye viscosity na mmiri mmiri nke ngwa agha ahụ, na-eme ka ihe owuwu ahụ dịkwuo nro ma na-ebelata uwe nke ngwá ọrụ ihe owuwu.

Mgbochi mgbawa: Site n'ịkwalite njide mmiri na nrapado nke ngwa agha, HPMC nwere ike igbochi ngwa agha na plasta nke ọma n'oge usoro ọgwụgwọ.

2. Mkpuchi na agba

Na agba na mkpuchi ụlọ, HPMC na-eji dị ka thickener, emulsifier na stabilizer. Ọrụ ya gụnyere:

Ịba ụba: Mụbaa viscosity nke agba, gbochie ịsagharị, ma melite otu nke mkpuchi.

Nkwụsi ike: Na-enyere aka ịnọgide na-enwe mgbasa nke pigmenti na ihe ndị na-ejuputa, na-egbochi nhazi na delamination.

Ngwongwo mgbochi-sag: Melite arụmọrụ mkpuchi nke agba ma gbochie ịsa na ntapu.

3. Ọgwụ na nri

N'ime ụlọ ọrụ ọgwụ na nri, HPMC na-ejikarị mbadamba, capsules na ihe mgbakwunye nri. Ọrụ ya bụ ndị a:

Ihe mkpuchi mbadamba: Dị ka ihe mkpuchi mbadamba mbadamba, HPMC nwere ike ijikwa ntọhapụ ọgwụ ma chebe ọgwụ ahụ site na mmiri na ikuku oxygen.

Shei Capsule: HPMC bụ isi ihe nke capsules anụ anaghị eri anụ, dabara adaba maka ndị anaghị eri anụ na ndị mmadụ na-enwe nfụkasị na capsules sitere na anụmanụ.

Ndị na-ekpu mmiri na emulsifiers: N'ime nri, a na-eji HPMC eme ihe dị ka ihe na-agbapụta, emulsifier na stabilizer iji meziwanye udidi na uto nri.

4. Ihe ịchọ mma

N'ụlọ ọrụ ịchọ mma, a na-eji HPMC na ngwaahịa ndị dị ka lotions, creams, shampoos na toothpastes. Isi ọrụ ya gụnyere:

Thickening: Na-enye ezigbo viscosity na agbanwe agbanwe, na-eme ka ngwaahịa dị mfe itinye na itinye.

Njirimara imepụta ihe nkiri: Mepụta ihe nkiri nchebe na-enweghị atụ iji kwalite mmetụta moisturize akpụkpọ ahụ.

Emulsification na Stabilization: Na-enyere emulsify na kwụsie ike ngwakọta mmiri-mmanụ iji gbochie stratification.

5. Ngwa ndị ọzọ

A na-ejikwa HPMC n'ọtụtụ ebe ndị ọzọ dịka:

Ink ibipụta: Ọ na-arụ ọrụ dị ka ihe na-agbapụta agba na stabilizer iji melite ogo mbipụta.

Agriculture: A na-eji ya dị ka ihe nkpuchi maka mkpuchi mkpụrụ na ọgwụ pesticide na ọrụ ugbo iji kwalite nrụpụta na ọnụ ọgụgụ mkpụrụ osisi.

Akwa: A na-eji ya na mbipụta textile na usoro ịcha akwa iji melite ogo mbipụta yana ngwa ngwa agba.

6. Atụmatụ na uru

HPMC na-arụ ọrụ dị mkpa na ụlọ ọrụ dị iche iche n'ihi njirimara anụ ahụ na kemịkal pụrụ iche. Isi njirimara ya gụnyere:

Mmiri solubility: HPMC nwere ike igbari ngwa ngwa na mmiri oyi ma ọ bụ ọkụ iji mepụta ngwọta colloidal transperent.

Biocompatibility na nchekwa: HPMC adịghị egbu egbu na adịghị emerụ ahụ, nwere ezigbo bioacompatibility, ma na-ejikarị ya n'ubi nri na ọgwụ.

Nkwụsi ike: Na-eguzogide acid, alkalis na salts, nwere ezigbo nkwụsi ike ma nwee ike ịnọgide na-arụ ọrụ ya na gburugburu ebe dị iche iche.

A na-eji Hydroxypropyl methylcellulose eme ihe n'ọtụtụ ebe na-ewu, mkpuchi, ọgwụ, nri, ihe ịchọ mma na ụlọ ọrụ ndị ọzọ n'ihi ike ya na arụmọrụ dị mma. Ọrụ ya nke ịkwa akwa, njide mmiri, emulsification na nkwụsi ike na-eme ka ọ bụrụ isi ihe dị na ngwaahịa dị iche iche, na-enye onyinye dị mkpa iji melite arụmọrụ ngwaahịa na ahụmahụ onye ọrụ.
