Hydroxypropylmethylcellulose (HPMC) bụ ihe na-arụ ọrụ dị iche iche nke a na-ejikarị eme ihe n'ọtụtụ ụlọ ọrụ n'ihi njirimara bara uru dị iche iche.Ọ bụ ihe e si na cellulose nweta, nke a na-enweta site n'ịgbanwe cellulose na chemically na propylene oxide na methyl chloride.A na-eji HPMC eme ihe n'ọtụtụ ebe na ụlọ ọgwụ, nri, ihe owuwu na ụlọ ọrụ ịchọ mma n'ihi ọmarịcha njide mmiri ya.Akwụkwọ a na-enye nyocha dị omimi banyere ọrụ njigide mmiri nke HPMC.
Ọrụ njide mmiri nke HPMC:
Njirimara mmiri nke HPMC bụ otu n'ime ihe kachasị mkpa maka iji ya mee ihe n'ọtụtụ ụlọ ọrụ.HPMC nwere ikike ijide mmiri dị elu n'ihi ọdịdị hydrophilic ya.Ọ na-amịkọrọ mmiri ma zaa ugboro ugboro nha mbụ ya, na-eme ka ọ bụrụ ezigbo ihe na-ejigide mmiri.Njirimara njide mmiri nke HPMC na-adabere n'ọtụtụ ihe dịka ogo ngbanwe, viscosity nke ngwọta HPMC, na ụdị ihe mgbaze ejiri.
Ogo nnọchi anya:
Ogo nke nnọchi (DS) nke HPMC bụ ihe dị mkpa na-emetụta arụmọrụ njide mmiri ya.DS nke HPMC na-ezo aka na ọnụ ọgụgụ nke hydroxyl otu ndị hydroxypropyl na methyl nọchiri anya n'ime molekul cellulose.HPMC nwere ogo dị elu nke nnọchi nwere ikike njigide mmiri dị elu karịa HPMC nwere ogo dị ala nke nnọchi.DS dị elu nke HPMC na-abawanye hydrophilicity nke molekul, na-eme ka njigide mmiri dị mma.
Viscosity nke ngwọta HPMC:
Viscosity nke ngwọta HPMC bụ ihe ọzọ na-emetụta ọrụ njigide mmiri nke HPMC.The viscosity nke HPMC ngwọta na-abawanye na mmụba nke HPMC itinye uche na ihe mgbaze.N'ihi ọnụnọ nke ọtụtụ ụmụ irighiri ihe HPMC na ihe mgbaze, ka viscosity nke ngwọta HPMC dị elu, ka mma na-ejigide mmiri.Nnukwu viscosity HPMC ngwọta na-etolite a gel-dị ka ihe owuwu na ọnyà ụmụ irighiri mmiri na-egbochi ha si evaporating.
Ụdị ihe mgbaze ejiri:
Ụdị ihe mgbaze a na-eji akwadebe ihe ngwọta HPMC nwekwara ike imetụta njide mmiri ya.HPMC na-agbaze na mmiri yana ihe mgbaze organic dị iche iche, dị ka mmanya, esters, na ketones.Ihe mgbaze eji akwadebe ihe ngwọta HPMC nwere ike imetụta omume ọzịza nke molekul.HPMC na-aza karịa na mmiri ma na-amịkọrọ mmiri karịa HPMC na ihe mgbaze organic.Tụnyere ihe ngwọta ihe mgbaze organic, HPMC nwere ihe njigide mmiri ka mma na ngwọta mmiri.
Ngwa nke HPMC na ụlọ ọrụ dị iche iche:
N'ihi ọmarịcha njide mmiri ya, a na-eji HPMC eme ihe n'ọtụtụ ụlọ ọrụ dịka ọgwụ, nri, ihe owuwu na ihe ịchọ mma.
Ụlọ ọrụ ọgwụ:
N'ime ụlọ ọrụ ọgwụ, a na-ejikarị HPMC eme ihe dị ka onye na-ekekọta, disintegrant na mkpuchi mkpuchi.A na-eji ya dị ka ihe nkedo na nkwadebe mbadamba nkume iji jikọta ihe oriri ọnụ.Dị ka ihe na-agbasasị, HPMC na-enyere aka ịkụda mbadamba nkume n'ime obere ihe dị n'ime afọ, nke na-eme ka mmịnye ọgwụ dịkwuo mma.A na-eji HPMC dị ka ihe mkpuchi iji kpuchido ọgwụ ahụ site na mmiri mmiri na ijikwa ntọhapụ ọgwụ.
ụlọ ọrụ nri:
N'ụlọ ọrụ nri, a na-eji HPMC dị ka emulsifier, stabilizer na thickener.A na-eji ya eme emulsize mmanụ na mmiri mmiri na-adabere na ya, mee ka nri kwụsie ike, na akwa sauces na gravies.A na-ejikwa HPMC dị ka ihe ndochi iji tinye nnukwu nri na nri.
Ụlọ ọrụ ihe owuwu:
N'ebe a na-ewu ihe owuwu, a na-ejikarị HPMC eme ihe na ciment dị ka ngwa agha na konkịtị.A na-eji ya dị ka onye na-ejigide mmiri iji gbochie ikuku nke mmiri na ngwakọta ciment.HPMC nwekwara ike melite arụmọrụ nke ngwakọta ciment ma belata mgbawa nke ihe.
Ụlọ ọrụ ịchọ mma:
Na ụlọ ọrụ ịchọ mma, a na-eji HPMC eme ihe dị ka thickener, emulsifier na onye na-edozi ihe.A na-eji ya na-eme ka ude na ude na-agbasi ike, na-eme ka mmanụ na mmiri na-edozi mmanụ na mmiri, na ntutu isi.
na ngwụcha:
N'ikpeazụ, ihe onwunwe mmiri nke HPMC bụ otu n'ime ihe kachasị mkpa na uru bara uru.HPMC nwere ikike njigide mmiri dị elu n'ihi ọdịdị hydrophilic ya, na-eme ka ọ nwee ike ịmịnye na ijide mmiri ma gbochie ya ịpụpụ.Ogo nke nnọchi, viscosity ngwọta na ụdị ihe mgbaze ejiri bụ ihe dị mkpa na-emetụta arụmọrụ njigide mmiri nke HPMC.A na-eji HPMC eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche dịka ọgwụ, nri, ihe owuwu na ihe ịchọ mma n'ihi ọmarịcha njide mmiri.
