Ni irihe tandukaniro riri hagati ya HPMC na HEC?

HPMC (HydroxyPropyl Methylcellselse) na Hec (HydroxyAyl Thereriulose) ni Itandukaniro rikomeye mu miterere n'imiti, imitungo, ibisabwa, n'ibindi.

1. Itandukaniro mumiterere yimiti
HPMC na Hec bafite abahanga ba selile batunganijwe na selile karemano (nka pamba cyangwa igiti), ariko baratandukanye mubasimbuye:

HPMC (HydroxyPropyl Methylcellse): HPMC iboneka mu gice cyangwa isimbuza rwose amatsinda ya hydroxyl (-Oh) ya methyl (-Hoh) na hydroxyPropyl (-ch₂ch (OH) kogosha kwa Celime. Urwego rwo gusimbuza methyl na hydroxyProppoyl rugena imitungo ya HPMC.
HEC (HydroxyAythyl Cellulose): Hec ni umuhanga wa selile wakozwe mu gusimbuza igice cy'amatsinda ya hydroxyl ya selile akoresheje amatsinda ya hydlexyerythyl (-CH₂₂oh), cyane cyane hydroxyWysiya.
Ibi bitandukanya imiterere yimiti bigira ingaruka muburyo bwabo, vicosiya, nibindi bimi byumubiri na shimi.

2. Kudakemu no gusebanya
HPMC: HPMC ifite amazi meza kandi arashobora gushonga mumazi akonje kugirango akore igisubizo gisobanutse. Irashobora kandi gushonga mubiti bya kama nka ethanol, acetone, nibindi, ariko umuvuduko wo gusebanya hamwe nimpamyabumenyi iratandukanye bitewe nibirimo byihariye. Ikintu cyingenzi cya HPMC nuko ishonga mumazi akonje, mugihe mugihe cyo gushyushya igisubizo gituruka mu mazure (ahinduka gel iyo ashyushye iyo akonjesha). Uyu mutungo ningirakamaro cyane mumirima nko kubaka no kurera.

HEC: HEC nayo irashonga mumazi akonje, ariko bitandukanye na HPMC, HEC ntabwo itandukanya amazi ashyushye. Kubwibyo, wec irashobora gukoreshwa hejuru yubushyuhe bwagutse. Hec ifite ubwo bwihanganira umunyu bukomeye no kubyinika imitungo kandi bikwiriye gukoreshwa mubisubizo birimo electrolytes.

3. Viscosity hamwe nimiterere yuburyo
Viscosity ya HPMC na HEC iratandukanye nuburemere bwabo bwa molecular, kandi byombi bifite ingaruka nziza kubyimba kubintu bitandukanye:

HPMC: HPMC yerekana pseudopplastique yo hejuru (ni ukuvuga, imitungo yombi ya shear) mubisubizo. Ibyamamare bya HPMC Ibisubizo bya HPMC bigabanuka mugihe ubwitonzi bwiyongera, bigatuma bahora basaba gukwirakwiza cyangwa gushushanya, ibisigazwa, ibisigazwa bya HPMC bigabanuka cyane hamwe nubushyuhe bwiyongera, kandi gel izashyiraho ubushyuhe runaka.

HEC: Ibisubizo bya Hec bifite ubushyuhe bwinshi kandi bwiza bwo kwinubira neza mu gipimo cy'iminsi mike, byerekana imiterere myiza y'urugendo rwa Newtonian. Mubyongeyeho, ibisubizo bya hec bifite impinduka ntoya mubidukikije birimo umunyu na electrolytes, kandi mugire umunyu mwiza. Bakoreshwa cyane mumirima isaba kurwanya umunyu, nko gukuramo amavuta no kuvura ibyondo.

4. Itandukaniro mubisabwa
Nubwo HPMC na HEC ishobora gukoreshwa nkabaribabi, ihindagurika, abahigo za firime, stabilizers, nibindi, imikorere yabo muburyo bwihariye bwo gusaba butandukanye:

Gusaba HPMC:
Inganda zubwubatsi: HPMC ikoreshwa nkumukozi wijimye hamwe numukozi ugumana amazi mubikoresho byo kubaka nka cement mirtar, ibicuruzwa bya Gypsum, na Ceramic Filic yishimye. Itezimbere imikorere ya minisiteri, irwanya gusebanya, no kuramba igihe cya minisiteri.
Imiti yimiti nibiribwa: mubuvuzi, HPMC ikunze gukoreshwa nkibikoresho byo gukorerwa ibinini nibikoresho bya Urwego kubitegura byarakomeje. Mu nganda zibiribwa, HPMC ikoreshwa nk'ibiribwa, cyane cyane nka emulsifier, ubumwe, na stabilizeri.
Inganda za Imiti ya buri munsi: HPMC ikoreshwa nka stabilizer ya emulizer, ubudozi, kandi ifite ibihembo bigize film bigize film muburyo bwo kwisiga hamwe nibicuruzwa byita kugiti cyawe.

Porogaramu ya Hec:
Gukuramo amavuta: Kubera ko Hec yihanganira umunyu, birakwiriye cyane gukoreshwa nkumukozi wijimye wo gucukura amazi no kuvunika amazi muminyu myinshi kugirango atezimbere ibintu byibyondo byibyondo.
Inganda zo gupakira: Hec ikoreshwa nkuwabyimbye kandi uhagaze mubikoti bishingiye kumazi. Irashobora kunoza amazi n'imikorere yo kubaka no gukumira ifuro yo kugandukira.
Inganda n'inganda: HEC irashobora gukoreshwa mu buso bwo hejuru mu mpapuro no kuvura nabi mu nganda z'ibintu kugira ngo ubyibunjiriro, utuje kandi uhindure imitungo.

5. Guharanira ibidukikije na biocompaget
HPMC: HPMC ikoreshwa muburyo bwa farumasi nibiribwa bitewe na biocompatbilite nziza na biodedadatable. Umutungo wacyo wagati kandi uhe ibyiza bidasanzwe mubushyuhe bwimiti-yoroheje. Byongeye kandi, HPMC ntabwo ari unicice, itagize ingaruka za electrolytes, kandi ifite umutekano mwiza kuri PH impinduka.

HEC: HEC ifite kandi biocompdatisobanuro nziza na biodegrafiya, ariko igaragaza ko iturika rikomeye mubidukikije. Noneho, wec ni uguhitamo neza aho kurwanya umunyu no kurwanya electrolyte birasabwa, nkibishushanyo bya peteroli, Ubwubatsi bwa Offshore, nibindi

6. Igiciro no gutanga
Kubera ko HPMC na wec bakomoka kuri selile karemano, harahamye ibikoresho fatizo, ariko biterwa nibikorwa bitandukanye byumusaruro, ibicuruzwa bya HPMC birarenze gato kurenza ibya Hec. Ibi bituma hec ikoreshwa cyane mubisabwa byihuse, nkibikoresho byubwubatsi, imiti yo murwego rwamavuta, nibindi

HPMC na Hec bombi ni ibigo bya selile. Nubwo batandukanye mumiterere yimiti, bombi bafite imirimo nko kwinubira, kubangamira, kugumana amazi hamwe na firime. Kubijyanye no gutoranya porogaramu, HPMC ifite umwanya wingenzi mubwubatsi, imyiteguro ya farumasi n'ibiribwa biterwa n'imitungo idasanzwe ya selling; Mugihe Hec agira uruhare runini munganda za peteroli kubera kwihanganira umunyu mwiza no guhuza ubushyuhe bwagutse. Byinshi byiza mu mabuye y'agaciro n'amazi. Ukurikije ibisabwa bitandukanye, guhitamo ibikomoka kuri selile Bikwiye birashobora kunoza imikorere nubukungu.
