Hydyli methylcelllose (hemc) bụ nondicose ether, nke bụ ngwaahịa na-agbanwe agbanwe na-enwetara site na iji hydroxyyligose (mc). Hemsc nwere ọtụtụ ihe pụrụ iche anụ ahụ na kemịkal, nke na-eme ka ọ bụrụ ihe owuwu, ọgwụ, nri na ubi ndị ọzọ.
1. Solbality na solubility
Hemsc nwere ezigbo ngegebility na mmiri. Ọ nwere ike igbachapu mmiri oyi iji mepụta uzo ma ọ bụ nke translucent ngwọta, yana n'ime ụfọdụ ịta ahụhụ, ihe ngwọta ya gosipụtara akụrụngwa viero. Ngwọta osisi nke hemsc nwere pseudoplastity, ya bụ, ọnụego shaar na-abawanye, viscosise nke ihe ngwọta ahụ na-ebelata. Ihe onwunwe a na - eme ka ọ bụrụ nke ọma na ngwa ndị dị ka mkpuchi ụkpụrụ na adresives.
2. Ndị na-eme mkpọtụ
Hemsc nwere ezigbo ihe onwunwe nke ma nwee ike ịbawanye viscosity nke sistemụ mmiri dabere na sistem mmiri. Mmetụta ya dị omimi abụghị naanị metụtara ịdị arọ molecular ibu, kamakwa na ihe ndị dị ka ịta, uru na ọnọdụ okpomọkụ nke ihe ngwọta. E mebere hemsc ebe n'ọtụtụ ụlọ dị ka ciment na ihe ndị dị nro n'ihi mmetụta dị nro ya n'ihi mmetụta dị nro ya na ọchịchọ ya dị ala nke sistemụ.
3. Njide mmiri
Hems nwere ezigbo ihe eji egbochi mmiri, nke na-eme ka ọ bụrụ ihe dị mkpa na ụlọ. Ọ nwere ike ijide mmiri na ihe ndị sitere na ciment, mee ka oge gboo ha, ma melite arụ ọrụ na akụrụngwa owuwu nke ihe ndị ahụ. Na mgbakwunye, ihe mgbochi mmiri nke hemsc na-emekwa ya n'ọtụtụ ebe na mkpuchi, adhesives na ọrụ nri, nke nwere ike igbochi mmiri na sistem ngwa ngwa.
4. Ngwongwo na-akpụ akpụ ihe nkiri
Hemsc nwere ike ịpụta ihe nkiri na-acha odo odo n'elu ya na ezigbo ihe ndị na-akpụ ihe nkiri. Ihe nkiri a nwere ụfọdụ ike na isi ike, enwere ike iji chekwaa mkpuchi ma gbochie eriri mmiri. Ngwongwo na-akpụ akpụ akwụkwọ na-eme ka ọ nwee ngwa dị mkpa na mkpuchi, na-ese, ndị ọrụ na ubi ndị ọzọ.
5. Kwụsịsi ike
Hems nwere ihe ndị na-akwụ ụgwọ kemịkalụ na ezigbo ndidi na gburugburu acid na alkali gburugburu. Ngwọta ya dịsi ike ka kwụsie ike na mbara igwe (ọ na-abụkarị 2-12) ma anaghị adịkarị mma ma ọ bụ ọdịda. Ke adianade dosc nwekwara ụfọdụ nkwụsi ike iji Ìhè, okpomọkụ na oxidation, nke mere na ọ ka nwere ike ịrụ ọrụ n'okpuru ọnọdụ jọgburu onwe ya.
6. Biotom na nchekwa
Hems bụ onyinye na-abụghị nke na-anaghị eme ihe na-adịghị akpata nfụkasị ahụ ma ọ bụ mmeghachi omume ọjọọ ndị ọzọ ma nwee ezigbo biocompatibility. Ya mere, n'ọhịa nke ọgwụ na nri, a na-ejikarị ya mee ihe dị ka nke na-agba mmiri, sie ike na capsule ihe. Nchekwa ya na-eme ka ọ na-eji ya niile na nlekọta anụ ahụ na ngwaahịa nlekọta anụ ahụ.
7. Ntughari nnu
E jiri ya tụnyere ụdị ndị ọzọ nke ndị ọzọ, hemsc nwere ndidi ka mma maka electrolytes. O nwere ike ịnọgide na-enwe ọhụụ ọhụụ na nkwụsi ike na sistemụ nwere nnukwu ihe dị elu nke nnu. Njirimara a na - enye ya uru na ụfọdụ ngwa pụrụ iche, dị ka mgbakwunye na - egwuri egwu na erimeri nri mmanụ.
8. Yobility na nkwusioru
Ngwọta Hedc nwere ezigbo lubrity na nkwusioru, nke nwere ike ime ka mmiri na ịdị n'otu na-ewuli elu. Nke a dị mkpa na ihe ndị dabeere ciment, nke nwere ike ime ka ọrụ na akụrụngwa mgbochi nke ihe ahụ.
A na-eji Hydythylthyl methylcelllose n'ọtụtụ ụlọ, ọgwụ, ihe oriri, nri, ihe ịchọ mma na ubi ya dị oke mma, ebe a na-eme ihe nkiri na nkwụsi ike. Ngwongwo ya na - adighi nma, ezigbo biocompatisibility na nkwụsi ike na-eme ka ọ bụrụ otu ihe mgbakwunye nwere ike ịme ọrụ dị mkpa n'ọtụtụ ngwa ọrụ mmepụta ọrụ dị iche iche.
