Hydroxypympylmethylcellose (HPMC) bụ polymer na-ahụ nke ọma na ụlọ ọrụ dị iche iche n'ihi ihe ndị pụrụ iche. Ogige a bụ ihe omimi nke cellose, polymer eke nke dị na mgbidi ụlọ ọrụ. Nchịkọta nke HPMC gụnyere ịgwọ Cellyy Oxide Oxide iji webata otu HDROXYLYYyl na Methyl chloride iji webata otu methy. Onye na-arụpụta polymer na-egosipụta ọtụtụ ụdị anụ ahụ na kemịkalụ, na-eme ya kwesịrị ekwesị maka iji ya na ọgwụ, owuwu, nri na ọrụ ndị ọzọ.
1.CHEMICICT na mejupụtara:
Hydroxypyl Methylcellose bụ polymer polymer nwere ihe dị mgbagwoju anya. Onye na-eme mkpọtụ nke polymer nwere cellulose, a na-anyụ agbụ glucose jikọtara ọnụ nke agbụ. A na-ewebata otu hydropyl site na dochie otu hydroxyl (-Oh) nwere otu propyl, a na-ewebata otu methyl n'otu ụzọ. The degree of substitution (DS) represents the average number of hydroxypropyl and methyl groups per glucose unit and affects the solubility, viscosity, and thermal properties of the polymer.
2. Ngụgụ:
Otu n'ime njiri maramara nke HPMC bụ omume ya. Ọ na-agbanye na mmiri oyi ma na-ekpo ọkụ, na-enye uru pụrụ iche n'ụdị dị iche iche. A ga-agbanwe agbanwe agbanwe site na idozi ogo nke dochie anya nke polymer. Ngwongwo a na - eme HPMC ezigbo onye na - ebuga ọgwụ maka nnyefe ọgwụ na - esonye, ebe ụkọ mgbasa na - arụ ọrụ dị oke mkpa na ọgwụ na - ahapụ Kinetics ọgwụ.
3. Viscosity:
Hydroxypylthylthylcelllose dị n'ọtụtụ ọkwa vissisels dị iche iche, dabere na ihe dị ka oke molecular, ogo uche. Viccositions nke HPMC Ngwọta nke Ngwọta HPMC na-enye ha ohere iji ọtụtụ ngwa ụlọ ọrụ, gụnyere ọgwụ, dị ka ndị na-eme ihe nkiri na-akpụ akpụ maka cosege.
4. Arụmọrụ nkiri na-eme ihe nkiri:
Ike fim ahụ nke HPMC dị oke mkpa na ngwa dị ka conings cociels, ebe a na-eji ya na-echebe ya iji kpuchie uto ọgwụ, ma na-edozi ọgwụ ọjọọ, ma mezie nkwụsi ike. Ihe nkiri HPMC doro anya ma na-agbanwe agbanwe, yana akụrụngwa ha nwere ike ịhazi ya site na idozi polymer ịta, ịdị arọ molecular na ọdịnaya plastiki.
5. Ọrụ ikuku:
Hydroxypyl Methylcelllose ngosi ezigbo ikuku n'ime otu okpomọkụ. Njirimara ikuku na-emetụta ihe ndị dị ka ogo usoro ihe nnọchi, ibu molecular, na ọnụnọ nke fọdụrụnụ. Ngwongwo ndị a na-eme HPMC adabara ngwa maka ngwa ebe nkwụsi ike nke ikuku dị oke mkpa, dị ka nkwadebe nke usoro ọgwụgwọ ọgwụ na-emepụta ihe.
6. Biotom:
Na ọgwụ na ubi biomedical, biocompatibility dị mkpa maka ihe eji arụ ọrụ nnweta ọgwụ. Hydroxypyllthyththythylcellloelu ka na-adị mma ma nwee ezigbo bayoompatibility. A na-ejikarị ya na usoro nke ọnụ ọgụgụ usoro onunu ogwu, ngwọta nke Ophthomic na sistemụ nnyefe ọgwụ na-achịkwa.
7. Njide mmiri na ihe Njirimara:
Ike HPMC nwere ijigide mmiri na nke sie ike na-eme ka ọ bụrụ ihe bara uru na ihe ndị na-ewu ụlọ dị ka ngwaahịa ciment. N'ime ngwa ndị a, HPMC na-eme ka onye na-eche nche, na-eme ka usoro nhazi na igbochi akwụkwọ ịkpọ oku. A na-ejikwa ahịhịa dị iche iche na ngwaahịa nri dị iche iche iji mee ka ederede na ọnụ.

Otu n'ime ngwa dị mkpa nke hydropyythylthylthylglthylcelllose dị na usoro nke sistemụ nnyefe ọgwụ na-achịkwa. Mgbakwunye nke polymer, viscosity, na ihe ndị na-akpụ akpụ ihe nkiri na-eme ka ịtọhapụ ọgwụ ọjọọ, na-enyere nnyefe ọgwụ na ebumnuche. Nke a bara uru karịsịa maka imeziwanye nnabata na mbelata nsonaazụ metụtara ya na ntọhapụ ọgwụ ọgwụ.
9.. Kwụsịsi ike n'okpuru gburugburu ụlọ
Ihe ngosi HPMC kwụsiri ike na otu ụzọ dị elu, na-eme ka ọ dị mma maka idobe ya na-achọ nkwụsi ike n'okpuru acidic ma ọ bụ alkaline ọnọdụ. Ihe onwunwe a bara uru na ọgwụ ọgwụ n'ihi na usoro ọgwụgwọ nwere ike zute gburugburu plọg dị iche iche na eriri afọ.

Omume ngwọta HPMC dị oke mkpa maka ngwa ebe akụrụngwa na-asọpụta dị oke mkpa, dị ka na nkwadebe nke mkpuchi, adhesives na gels. Enwere ike ịhazi akụrụngwa nke rheloulor site na ịhazigharị ịta na molecular ịdị arọ nke Hpmc iji nweta njirimara na-asọ maka njide.
Hydroxypyl Methylcelllose abụrụla polymer dị mkpa na ụlọ ọrụ dị iche iche n'ihi ngwakọta ya pụrụ iche, viscosity, ike na-akpụzi ikike na biocompatisibility. Ọnọdụ ya na-eme ka ọ dị mma maka ọtụtụ ngwa, site na ọgwụ na ihe ndị metụtara ihe oriri na ịchọ mma. Dị ka ndị nchọpụta nọgidere na-enyocha usoro na ngwa ọhụrụ, Njirimara nke Hydropyythyllillilose ga-etinye aka na mpaghara dị iche iche, na-enyere aka dị mkpa na sayensị na ụlọ ọrụ.
