Hydroxypyl Methymer) bụ polymer nke nwere hydrophobic na akụrụngwa hydrophilic, na-eme ya pụrụ iche n'ọtụtụ ngwa ndị gafere ọrụ dị iche iche. Iji ghọta hydrophobity na hydrophilicy nke Hpmc, anyị kwesịrị ịmụ ihe owuwu ya, Njirimara na ngwa na omimi.
Ọdịdị nke hydypropyythylthylcelllose:
HPMC bụ usoro nke cellose, polymer sitere polymer nke dị na mgbidi osisi. Mgbanwe nke cellulose na-agụnye iwebata hydropyyl nathyl ke yethyl banye na balluse backbone. Mgbanwe a gbanwere Njirimara nke polymer, na-etinye ihe akọwapụtara nke ọma maka ọtụtụ ngwa.
Hydrophicaly nke hpmc:
Hydroxy:
HPMC nwere Hydropyyl dị iche iche ma na-eme hydrophilic. Ndị otu Hydroxy nwere mmekọrịta dị elu maka ụmụ irighiri mmiri n'ihi njikọta hydrogen.
Ngalaba Hydroxypyl nwere ike imekọ ihe eji eme mmiri hydrogen na molecules mmiri, na-eme hpmc soluble na mmiri ruo n'otu oge.
Methyl:
Ọ bụ ezie na otu methyl na-enye aka na hydrophobity nke molekul, ọ naghị egbochi hydrophility nke otu hydroxyyl.
Otu methyl dịtụ pol polar, mana ọnụnọ nke otu hydroxyyl na-ekpebi agwa a hydrophilic agwa.
Hydrophobity nke hpmc:
Methyl:
Ndị otu methyy na HPMC na-ekpebi ohere ụfọdụ hydrophodicity ya.
Ọ bụ ezie na ọ bụghị hydrophobic dị ka polymers ụfọdụ nke ọma, ọnụnọ nke ìgwè methy na-ebelata hydrophility nke hpmc.
Ihe nkiri na-akpụ Njirimara:
A maara HPMC maka ihe nkiri na-akpụzi ihe nkiri ya ma na-erikarị na ngwa ọgwụ na ịchọ mma. Hydrophobisicity na-atụnye ụtụ na usoro ihe nkiri echebe.
Mkparịta ụka na ihe ndị na-abụghị polar:
Na ụfọdụ ngwa, HPMC nwere ike imekọrịta ihe na ihe ndị na - abụghị polar n'ihi hydrophodicity ya. Ihe onwunwe a dị oke mkpa maka sistemụ nnyefe ọgwụ na ụlọ ọrụ ọgwụ.
Ngwa nke HPMC:
Ọgwụ:
A na-eji HPMC mee ihe n'ọtụtụ ebe na ọgwụ na-emepụta ọgwụ dị ka ihe mkpuchi, ihe nkiri mbụ, na viofice modifier. Ikike ị na-eme ihe nkiri na-eme ka ọ na-eme ka ọgwụ na-achịkwa ọgwụ.
A na-eji ya na usoro onunu ogwu siri ike dịka mbadamba na capsules.
Industrylọ ọrụ owuwu:
N'ebe a na-ewu ihe owuwu, a na-eji HPMC mee ihe na ngwaahịa ciment iji meziwanye ọrụ, njigide mmiri na adresion.
Hydrophilicity na-enyere aka idobe mmiri, ebe hydrophobity na-enyere adhesia.
Industrylọ ọrụ nri:
A na-eji HPMC mee ihe dị ka nke na-echekwa na ụlọ ọrụ nri. Ọdịdị ya hydrophilic na-enyere aka n'ụdị gọọmenti kwụsiri ike ma na-achịkwa viscosity ngwaahịa.
cosmetic:
Na usoro ịchọ mma, a na-eji HPMC mee ihe dị ka ude na lotions n'ihi ụdị ihe nkiri ya na ndị na-eto eto.
Hydrophilicity na-eme ka ezigbo hydration nke anụahụ.
na ngwụcha:
HPMC bụ polymer nke bụ ma hydrophilic na hydrophobic. Izu oke n'etiti hydroxyl na methyl na nhazi ya na-enye ya ihe pụrụ iche, na-ekwe ka ọ dị ọtụtụ ngwa. Ghọta Njirimara ndị a dị oke mkpa ịhazi HPMC na iji ahaziri iche na ụlọ ọrụ dị iche iche, ebe a na-eji ihe ndị na-enweghị isi na-emekọrịta ihe maka ebumnuche dịgasị iche iche.
