N'etiti ha, hydroxypyl methylcelllose (hpdropyl methylcellose), a na-ejikarị ihe mkpuchi mmiri n'ihi ihe nkiri na-etolite, na-emekwa mmiri, mmiri na ngwa agha. , karịsịa na ubi nke sistemụ mkpuchi na mpụga, ngwa ngwa akọrọ, mkpuchi ọkụkụ na mpaghara ndị ọzọ.

1.basic njirimara nke HPMC

HPMC bụ ebe ikuku na-egbu egbu na-enweta site na mmiri osisi cellulose. Ihe isi ya gụnyere:
Mmiri solubility: HPMC nwere ike ị nweta ngwọta colloidal na mmiri nwere ezigbo mmiri na mgbasa.
Thischende: ọ nwere mmetụta dị elu nke nwere ike ịbawanye viscosity nke mmiri mmiri ọbụlagodi na obere.
Ngwongwo nke fim: HPMC nwere ike mejupụta ihe nkiri dị na elu nke mkpụrụ iji mee ka ndọnye ihe mkpuchi ahụ.
Eserese mmiri: O nwere njigide siri ike, nke nwere ike igbochi oke ikuku nke mmiri wee gbatị oge ihe mkpuchi ihe.
Ntughari: Site na igbanwe molecular owuwu nke hpmc, solublity, viscosity nwere ike idozi ihe ndi ozo iji gboo mkpa nke ihe ndi ozo.
Omume ndị a pụrụ iche na-enye atụmanya sara mbara nke ngwa na ihe mkpuchi ikuku.

2. Arụ ọrụ nke HPMC na ihe mkpuchi ikuku

Mee ka njikọta na ndọghachi azụ
Na sistemụ mpụga, HPMC dị ka ihe mgbochi nwere ike budata ndọlite ​​n'etiti mkpuchi na isi mgbidi. Ihe nrịba ama nke ihe mkpuchi ọdịnala dịka osisi polystyrene foom (EPS) na-emetụtakarị ihe mpụga mpaghara (nke dị ka iru mmiri na mgbanwe okpomọkụ. Site na ịkwalite ngwa agha ma ọ bụ nrapado, HPMC nwere ike imeziwanye ikike nke dị n'etiti ihe mkpuchi na ihe dị ka peesh ulo, ma melite nkwụsi ike na ịdịgide nke ụlọ ahụ.

Meziwanye ihe owuwu
Ọrụ owuwu nke ihe mkpuchi na-emetụta ya na arụmọrụ arụ ọrụ. HPMC nwere ike imezi arụmọrụ ihe mkpuchi nke ihe mkpuchi, na-enye ọnya na-agbanwe ọkụ, wee hụ na ndị ọrụ ụlọ nwere ike ịrụ ọrụ nke ọma. Dịka ọmụmaatụ, ịgbakwunye hpmc na ngwa agha akọrọ nwere ike ime ka ọ dị mma nke ngwa agha ahụ, na-abawanye nke mmiri ya, na-eme ka okwute ahụ ghara ịghọrọ ya mgbe ị na-ewuli elu.

Meziwanye arụmọrụ mkpuchi
HPMC nwere ezigbo ihe eji eme mmiri, nke nwere ike igbu oge ọpụpụ mmiri, na-ekwe ka mkpuchi ahụ dị ogologo oge, si otú ahụ na-eme ka ịchafụ na ịmịcha mmiri. Ngwongwo a dị ezigbo mkpa na mpaghara oyi, dị ka ọ na - eme ka ọ na - eme ka ihe ndị a na - eme ihe na - emepụta ihe n'oge a na - agbadata na obere okpomọkụ.

Mmiri mgbochi na mgbochi
Ka oge na-aga, enwere ike ikpughere mkpuchi na ụzarị na ụza UV, na-akpata mmebi arụmọrụ. HPMC nwere ụfọdụ ọrụ mgbochi mmiri na ọrụ mgbochi ma nwee ike ime ka ihu igwe na-eguzogide ihu igwe na ntuli aka nke ihe mkpuchi. Site na ịgbakwunye hpmc ahụ kwesịrị ekwesị, mmiri na-eguzogide ihe onwunwe nwere ike ịba ụba, na-egbochi mkpuchi mkpuchi na-apụta na ọzịza na ọsụsọ na ọ na-eme ka ihe mkpuchi ikuku dị mma ruo ogologo oge.

Melite nkwụsi ike
Ihe owuwu nke HPMC nwere hydropyyl na methyl, nke na-enye ya ezigbo ikuku. Na gburugburu okpomọkụ, Hpmc nwere ike ịnọgide na-anọgidesi ike na usoro nhazi nke usoro, na-ezere mgbanwe mgbanwe na arụmọrụ nke ihe ọkụkụ na-akpata. Ya mere, na ihe mkpuchi ikuku eji eme ihe eji eme ihe n'udo, mgbakwunye nke hpmc na-enyere aka ijigide arụmọrụ mkpuchi ikuku.

Ihe atụ nke hpmc na ihe mkpuchi ikuku dị iche iche

Sistemụ Mgbidi mpụga
Na usoro mpụga Midie, a na-ejikarị HPMC mee ihe ndị ọzọ (dịka ciment, gypsum, wdg). Ọrụ ya bụ iji mee ka njikọta na ngwa agha dịkwuo elu, melite adhesion n'etiti mkpanaka dị iche iche, ma belata nsogbu dị ka peeling na ikuku na-akpata mgbanwe na ikuku na ikuku.

Mkpuchi mkpuchi na-adịghị mma
A na-ejikwa HPMC mee ihe n'ọtụtụ ebe mkpuchi mkpuchi. Achịcha mkpuchi na mpụga ga-enwe ezigbo ndọnye adhesion na ezigbo ihe nkiri na-akpụ akpụ. HPMC nwere ike ime ka otu ịdị n'otu na-eme ka ahụ dịkwuo mma, na-agba mbọ iguzogide mkpuchi ahụ, na-agba mbọ kwụsie ike na gburugburu ebe obibi ma ghara imetụta ogologo oge.

Ahịhịa akọrọ
Ahịa kpọrọ nkụ bụ ihe mkpuchi mkpuchi. Site na ịgbakwunye hpmc, ọ nwere ike ọ bụghị naanị imeziwanye mmiri nke ngwa agha, ma na-eme ka oge owuwu ahụ, na-agbatị oge ọrụ, ma mezie ọrụ nke ngwa agha. Karịsịa na gburugburu ebe okpomọkụ dị ala, njigide mmiri nke HPMC nwere ike ịgba mbọ hụ na ngwa agha.

Ngwa nke HPMC na ihe mkpuchi ikuku nwere nkwalite arụmọrụ dị mkpa. Site na ịkwalite adresion, imeziwanye arụmọrụ, na-eme ka ihe mkpuchi mmiri, akụrụngwa mgbochi na mgbochi mgbochi nke ihe mkpuchi, na-agbasa ndụ ha na-akpata. Dịka ihe owuwu ụlọ ọrụ na-ewu ewu maka nchebe gburugburu ebe obibi na nchekwa ike na-aga n'ihu na atụmanya ngwa na ihe mkpuchi ikuku ma kwesiri inyocha nyocha na mmepe.
