Kedu ọrụ hydroxypropyl methylcellulose na-arụ n'ụdị nrapado?

Hydroxypropyl Methylcellulose (HPMC) bụ ihe a na-ejikarị cellulose ether eme ihe nke a na-ejikarị eme ihe n'ụdị nrapado.

Ọkpụrụkpụ:

Hydroxypropyl methylcellulose bụ ihe na-arụ ọrụ nke ọma nke nwere ike imeziwanye viscosity na njirimara rheological nke adhesives. Site n'ịbawanye viscosity nke usoro ahụ, HPMC nwere ike imeziwanye arụmọrụ nke nrapado ahụ, gbochie gluu na-asọpụta ngwa ngwa, hụ na enwere ike kpuchie gluu nke ọma n'elu mkpụrụ n'oge a na-ewu ihe, ma zere ntanye na sagging. .

Njirimara njikọ:

HPMC nwere ihe ejikọtara ọnụ nke ọma ma nwee ike ịmepụta akwa njikọ siri ike n'elu ihe dị iche iche. Site na usoro ihe omimi nke yinye cellulose ya, ọ na-emepụta mmekọrịta anụ ahụ na nke kemịkalụ na elu nke mkpụrụ ahụ iji mepụta ike njikọ siri ike, si otú a na-eme ka ike njikọ nke nrapado dịkwuo mma.

Ndokwa mmiri:

HPMC nwere ezigbo njide mmiri ma nwee ike ijigide mmiri nke ọma na usoro nrapado, na-egbochi nrapado site na ịgbawa ma ọ bụ ibelata ike n'ihi mmiri na-efu ngwa ngwa n'oge usoro ihicha. Njirimara a dị mkpa karịsịa na ihe nkwụnye mmiri na-adabere na mmiri, nke nwere ike ịgbatị oge oghere nke nrapado ma melite ngwa ngwa.

nkwụsi ike:

HPMC nwere ike imeziwanye usoro nkwụsi ike nke nrapado ma gbochie idozi na delamination nke ihe siri ike na usoro. Site n'ịbawanye otu na nkwụsi ike nke usoro ahụ, HPMC na-enyere aka ịnọgide na-echekwa ogologo oge na arụmọrụ ngwa nke nrapado.

Njirimara mmepụta ihe nkiri:

Hydroxypropyl methylcellulose nwere ezigbo ihe na-emepụta fim ma nwee ike ịmepụta otu ihe nkiri n'elu nke mkpụrụ. Ihe nkiri a nwere ọkwa ụfọdụ nke ngbanwe na mgbanwe ma nwee ike ime mgbanwe maka obere nrụrụ nke mkpụrụ, na-egbochi nrapado site na mgbawa ma ọ bụ peeling n'ihi nrụrụ nke mkpụrụ.

Solubility na mgbasa:

HPMC nwere ezigbo mmiri solubility na mgbasa, ma nwee ike igbari ngwa ngwa na mmiri oyi wee mepụta ngwọta transperent ma ọ bụ translucent viscous. Ya mma solubility na dispersion ka HPMC mfe iji rụọ ọrụ na mix n'oge nkwadebe nke adhesives, na ike ngwa ngwa nweta chọrọ viscosity na rheological Njirimara.

Nguzogide ihu igwe:

HPMC nwere ezigbo nkwụsi ike na gburugburu ebe siri ike dị ka oke okpomọkụ, obere okpomọkụ, na iru mmiri, ma nwee ike ịnọgide na-arụ ọrụ nke ntanye ahụ kwụsiri ike. Mgbochi ihu igwe a na-eme ka adhesives nwere HPMC dabara maka gburugburu ihe owuwu dị mgbagwoju anya na oge ojiji.

Nchedo gburugburu ebe obibi:

Dị ka ihe sitere na cellulose eke, HPMC nwere ezigbo biodegradability na ihe nchebe gburugburu ebe obibi. Ọ naghị emepụta ihe ndị na-emerụ ahụ n'oge a na-eji ya na mkpofu, na-eme enyi na gburugburu ebe obibi, ma dabara na mmepe mmepe nke ụlọ ọrụ kemịkalụ akwụkwọ ndụ akwụkwọ ndụ nke oge a.

Hydroxypropyl methylcellulose na-arụ ọtụtụ ọrụ dị mkpa na nhazi nrapado. Ọ na-eme ka viscosity dịkwuo mma, na-eme ka ihe ndị dị n'ime ya dịkwuo mma, na-ejigide mmiri mmiri, na-eme ka usoro ahụ dị ike, na-emepụta ihe nkiri nchebe, na-eme ka mgbasa na mgbasa, na-enye nkwụsị ihu igwe, na gburugburu ebe obibi. HPMC emela nke ọma n'ozuzu arụmọrụ nke adhesives na ọtụtụ ebe na-eji na-ewu, ngwá ụlọ, nkwakọ, ụgbọala na ubi ndị ọzọ, na-aghọ ihe dị oké mkpa na mkpa akụrụngwa na nrapado formulations.
