HPMC maka ewu akụrụngwa

Hydroxypropyl methyl cellulose (HPMC) bụ ihe sịntetik, polymer soluble mmiri nke a na-ejikarị dị ka ihe mgbakwunye na ụlọ ọrụ ihe owuwu.A na-agbakwunye ihe a na-agbanwe agbanwe n'ọtụtụ ngwaahịa ihe owuwu iji mee ka ihe onwunwe ha dịkwuo elu, dị ka ịba ụba viscosity, imeziwanye ọrụ ọrụ, na inye ihe mgbochi nchebe megide mmiri mmiri.

A na-enweta HPMC site na cellulose, nke bụ polymer eke nke dị ukwuu n'alaeze osisi.Iji mepụta HPMC, a na-agbanwe cellulose na kemịkalụ iji mee ka mmiri na-eme ka mmiri dịkwuo elu, na-enye ohere iji ya mee ihe n'ọtụtụ ngwa.Usoro mgbanwe kemịkalụ gụnyere ngbanwe nke ụfọdụ otu hydroxyl na cellulose na otu hydroxypropyl.Ngwaahịa a na-esi na ya pụta bụ ntụ ntụ na-acha ọcha, nke na-agbaze ngwa ngwa na mmiri, na-eme ka ngwọta doro anya, viscous.

Otu n'ime isi ojiji nke HPMC na ụlọ ọrụ ihe owuwu bụ dị ka thickener na rheology modifier.Mgbe agbakwunyere na ngwaahịa ihe owuwu, ọ na-abawanye viscosity nke ngwaahịa ahụ, na-eme ka ọ dị mfe itinye ma na-enye ya na-agbanwe agbanwe.Dịka ọmụmaatụ, a na-agbakwunye HPMC na nrapado taịlị iji kwalite ọrụ ha na mgbasa.Nke a na-enye ohere ka a na-etinye nrapado taịlị ahụ nke ọma na mkpụrụ osisi ahụ, na-eme ka njikọ siri ike na nke na-adịgide adịgide.

HPMC na-enyekwa ihe mgbochi mgbochi mmiri.Mgbe etinyere ya na ngwaahịa ihe owuwu dị ka ngwa agha, HPMC na-enyere aka belata oke mmiri nke ngwaahịa ahụ na-etinye, na-egbochi ya ịsa ngwa ngwa.Nke a na-enye ohere ka ngwaahịa ahụ rụọ ọrụ ogologo oge, na-eme ka ọsọ ọsọ na ịrụ ọrụ nke ọma rụọ ọrụ.Na mgbakwunye, ihe mgbochi nchebe nke HPMC na-enye na-enyekwa aka igbochi efflorescence (ịkwalite nnu n'elu igwe), nke nwere ike imebi ọdịdị nke ngwaahịa emechara.

Ihe ọzọ dị mkpa eji HPMC eme ihe na ụlọ ọrụ ihe owuwu bụ ihe nkedo.Mgbe agbakwunyere na ngwaahịa ihe owuwu, HPMC na-enyere aka ijikọ akụkụ ndị ọzọ ọnụ, na-eme ka ike zuru oke na ịdịte aka nke ngwaahịa ahụ.Dịka ọmụmaatụ, a na-agbakwunye HPMC na ngwaahịa gypsum dị ka ogige nkwonkwo akọrọ na plasta, iji nyere aka melite nrapado ha na mkpụrụ.

Na mgbakwunye na iji ya na-ewu ụlọ, a na-ejikwa HPMC n'ọtụtụ ụlọ ọrụ ndị ọzọ, gụnyere nri, ọgwụ na ụlọ ọrụ ịchọ mma.Dịka ọmụmaatụ, a na-ejikarị HPMC eme ihe dị ka thickener na stabilizer na ngwaahịa nri, yana dịka onye na-ekekọta mbadamba n'ichepụta na ụlọ ọrụ ọgwụ.

Enwere ọtụtụ akara ule HPMC dị, nke ọ bụla nwere ihe dị iche iche na-eme ka ọ dabara maka ngwa dị iche iche.Akara ule kachasị nke HPMC bụ obere, ọkara na viscosity dị elu, nke akọwara site na ịdị arọ molekụla nke polymer.A na-ejikarị HPMC viscosity dị ala na ngwa nke chọrọ ngwọta viscosity dị ala, dị ka n'ịmepụta ihe nkpuchi dị ala.A na-ejikarị HPMC viscosity ọkara na ngwa chọrọ ngwọta viscosity na-agafeghị oke, dị ka n'ịmepụta ihe nrapado taịlị.A na-ejikarị HPMC viscosity dị elu na ngwa ndị chọrọ ngwọta viscosity dị elu, dị ka n'ichepụta ngwaahịa siri ike na creamy, dị ka shampoos na lotions.

N'ikpeazụ, HPMC bụ ihe owuwu dị mkpa nke nwere ọtụtụ ihe eji eme ihe na ụlọ ọrụ ihe owuwu.Site n'ịdị arọ na mgbanwe rheology, na nchebe mmiri na njide, HPMC bụ ihe mgbakwunye dị mkpa nke na-eme ka njirimara nke ngwaahịa ihe owuwu na-eme ka ọ dịkwuo mma.
