Hydroxypyl Methylcellose (HPMC) bụ polymen ogige enwetara site na modemfication osisi cellulose. O nwere ezigbo mmiri gazie, na-abụghị ihe na-abụghị ihe na-adịghị mma, enweghị isi na ezigbo biocompatalitibility. Ya mere, a na-eji ya ebe niile na agba, owuwu, ogwu, nri na ubi ndị ọzọ. Na ụlọ ọrụ agba, HPMC na-arụ ọrụ dị mkpa dị ka Trimenar, nke nwere ike ime ka arụmọrụ, nkwụsi ike na nhazi teknụzụ.
1. Ọrụ nke HPMC dị ka agba agba
HPMC na-egwu ọrụ ndị a dịka nke na-esote na agba:
(1) mụbaa viscits nke agba
HPMC nwere ike ịmịcha mmiri ma zaa mmiri mmiri na-achakarị mmiri site na polymer yinye ya, nwekwuo mmekọrịta n'etiti molecules, ma si otú ahụ na-abawanye viscosis nke agba ahụ. Mmụba na viscosictosis na-eme ka ihe ndị na-adịghị mma nke agba ahụ mee ka ị na-eme ka ihe mkpuchi kpuchie ya. Kpamkpam, Hpmc nwere ike ime ka brung na ịmịcha ọrụ nke agba na-ezere oke ma ọ bụ ịnya.
(2) melite Njirimara Njirimara
Ngwa nke HPMC na mkpuchi nwere ike ime ka ihe onwunwe ha dị mma, karịchaa na ọnụego dị elu na ọnụego Shear, ma nwee ike ịnọgide na-enwe ọhụụ na oke na nkwụsi ike. Nke a dị ezigbo mkpa maka nhazi mkpuchi n'okpuru ọnọdụ usoro dị iche iche, ọkachasị maka ihe owuwu mgbe ị na-ehichapụ nnukwu mpaghara. Site na idozi uche na molecular arọ nke hpmc, mmiri ahụ nwere ike idozi, nke mere na ọ dịghị mfe ịba ọsọ ọsọ n'oge eji, ma nwee ike ịnọgide na-arụ ọrụ dị mma.
(3) Meziwanye ebe obibi nke mkpuchi
Mmetụta ndị na-emekarị nke HPMC na mkpuchi abụghị naanị iji mụbaa viscosity, kamakwa iji meziwanye ọkwa mkpuchi. A na-ekenye ike na-ezo aka ike nke mkpuchi ahụ na-ekesakarị ya n'elu mkpụrụ mgbe ịsacha na-enweghị ihe na-enweghị atụ ma ọ bụ na-enweghị nchịkọta. HPMC na-abawanye esemokwu dị elu ma na-emekwa ka njiri mara nke mkpuchi ahụ, nke mere na mkpuchi na-akpụzi otu edo na-adịkwa mma na-atọ ụtọ na elu nke mkpụrụ.
(4) mee ka oge gboo kpuchie ya
Dịka onye na-eto eto, Hpmc nwekwara ọrụ nke ogologo oge nke mkpuchi. Oge na-emeghe na-ezo aka n'oge mkpuchi ahụ ga-arụ ọrụ n'oge usoro ngwa. N'oge a, oge a na-enyere aka igbochi mkpuchi site na ihicha ngwa ngwa n'oge usoro brushi, nke na-eduga na akara akara ma ọ bụ ihe na-adịghị mma. HPMC na-eme ka oke mkpuchi nke mkpuchi ahụ, na-ekwe ka mmiri kpuchie mmiri iji nọgide na-enwe ọhụụ na-eme ka ọ dị ogologo oge, na-enyere usoro mkpuchi dị nro.
(5) Kwado nkwụsi ike nke mkpuchi
Mmetụta ndị na-emekarị nke HPMC na-enyere aka ịkwali nkwụsi ike nke mkpuchi, karịsịa na usoro mkpuchi mmiri, ọ nwere ike idozi ndapụta, ma na-agbatị oge nchekwa nke mkpuchi. Site na imeghari oke nke Hpmc nke Hpmc, ike ga-ebuli ya ka ọ ghara imegharị ma ọ bụ na-enweghị isi n'oge nchekwa ogologo oge.
2. Ngwa nke HPMC na mkpuchi mmiri
A na-akwalite nke dabere na mmiri mmiri na-adịbeghị anya n'ihi nchebe gburugburu ha, ndị na-abụghị ntụpọ, na obere mmetọ. Ngwa nke HPMC na akwa mkpuchi mmiri dị ezigbo mkpa. Ọ bụghị naanị na-arụ ọrụ dị ka nke ukwu, kamakwa na-arụ ọrụ dị mkpa na akụkụ ndị a:
(1) Meziwanye mmiri na ọrụ
Ọ na-adịkarị anya mmiri nke mkpuchi mmiri mmiri na ọdịnaya siri ike. HPMC nwere ike idozigharị rhiology nke mmiri iji nọgide na-enwe ọhụụ dị elu na ọnụego Shear, si otú a na-elekọta ezigbo ọrụ n'oge mkpuchi. Na mgbakwunye, HPMC na-ebulikwa nke Tomatopy nke mkpuchi, ya bụ, mkpuchi nwere ụfọdụ vistic na steeti n'oge usoro ngwa ngwa iji kwado usoro ngwa ngwa.
(2) melite nguzogide mmiri nke mkpuchi nke mmiri
HPMC Molecules nwere otu hydrophilic, nke nwere ike ime ka ahụ dị omimi nke mkpuchi mmiri nke mmiri. N'oge a na-asa mmiri nke mkpuchi, Hpmc nwere ike belata nsogbu nke ịghasa mmiri na-akpata mmiri, si otú a na-eme ka mmiri guzogide na ndọpụta nke mkpuchi.
(3) Kwalite nghọta na gloss nke mkpuchi
N'ihi ike ya dị elu, Hpmc nwere ike inyere uwe mkpuchi dabere n'ụkwụ na gloss. N'ime ụfọdụ ngwa mkpuchi pụrụ iche, dị ka variques na mkpuchi doro anya, iji hpmc nwere ike ịnọgide na-edobe ụkpụrụ mkpuchi ma meziwanye mkpuchi nke mkpuchi ikpeazụ.
3. Ngwa nke HPMC na mkpuchi mkpuchi
Na mkpuchi mkpuchi nke sitere na mmanụ, a na-eji HPMC bụ ihe dị ka ihe na-achịkwa Rhiteology. Ọ bụ ezie na HPMC onwe ya bụ oke mmiri - soluble, mmetụta ọ na-arụ dị mma na mkpuchi mkpuchi nke dabeere na mmanụ ebe niile. N'ime ihe osise ndị dabeere na mmanụ, HPMC nwere ike idozigharị viscosity nke agba ahụ, melite brulability nke agba ahụ, na-eme ka nkwụchi nke agba ahụ.
4. Uru nke HPMC dị ka onye ukwu
E jiri ya tụnyere ndị ọdịnala ọdịnala, ngwa nke HPMC na eserese nwere uru ndị a dị mkpa:
Ọmarịcha nchebe gburugburu ebe obibi: HPMC bụ ihe na-enye oke sellulose na enweghị ike imerụ ihe ọjọọ, yabụ ọ dị mma iji na eserese ma ghara imerụ gburugburu ebe obibi.
Mmiri siri ike, HPMC nwere ezigbo sogrọbility na nkwụsi ike na ihe osise mmiri, nwere ike ịnye nsonaazụ dị mma na-akpata, ọ gaghị emetụta ihe ndị ọzọ nke agba ahụ.
Ezi arụmọrụ dị mma: HPMC nwere ike ime ka arụmọrụ owuwu nke agba ahụ, zere iwechamịghe na mkpuchi adịghị mma, ma dịkwa mma maka usoro mkpuchi mkpuchi dị iche iche.
Meziwanye ebe nkwụsi ike: HPMC nwere ike idozi anụ ahụ na kemịkal nke agba ahụ ma belata ihe dị iche iche nke nwere ike ime n'oge nchekwa.
Dị ka agba agba, HPMC enweghị ike ịbawanye viscosity nke agba ahụ ma melite oology, kamakwa ịkwalite nkwụsi ike nke agba ahụ. A na-ejikarị ya na eserese mmiri na ihe osise ndị dabeere na mmiri. Site na idozi usoro ihe owuwu ya na ntinye uche ya, arụmọrụ nke mkpuchi nwere ike ịgbanwe iji gboo mkpa nke ụdị mkpuchi dị iche iche. Na mmụba na-abawanye maka mkpuchi ebe obibi na ebe dị ala, atụmanya nke HPMC ga-abawanye ma ọ ga-abụ otu n'ime ihe mgbakwunye igodo na mkpuchi mkpuchi.
