HydroxyPropy muag methylcellose (HPMC) plays lub luag haujlwm tseem ceeb hauv kev sib xyaw ntawm cov tshuaj khib nyiab ntub dej. Nws lub luag haujlwm tseem ceeb suav nrog cov dej cia, ua kom tuab, yuag, txhim kho lub sijhawm ua haujlwm tau zoo thiab txuas ntxiv.
1. Dej khaws cia
Lub luag haujlwm tseem ceeb tshaj plaws ntawm HPMC nyob rau hauv ntub cug yog dej khaws cia. Nws tuaj yeem txo qis cov evaporation tus nqi ntawm cov dej hauv lub cug. Ntawm no yog cov dej tseem ceeb tshaj yog:
Tiv thaiv kom tsis txhob poob dej thaum tsim nyog, HPMC tuaj yeem txo cov dej huv thiab ua kom muaj kev txhim kho kom muaj zog thiab sib khi ntawm lub tshuaj khib.
Txhim kho kho kom zoo: Cug nrog cov dej zoo yuav ua kom cov kab xeb kom qhuav, txo qhov kev ua kom zoo thiab vability ntawm lub cug.
Lub sijhawm qhib qhib, HPMC tuaj yeem txuas ntxiv lub sijhawm qhib ntawm lub tshuaj khib nyiab tuaj yeem ua haujlwm ntawm lub sijhawm ntev dua, yog li kev txhim kho kev siv tshuab siv tau ntev dua.
2. Thickening
Raws li cov tuab, HPMC tuaj yeem nce cov kev sib xws thiab viscosity ntawm cov ntoo ntub-mixed. Nws cov kev cuam tshuam tshwj xeeb suav nrog:
Txhim kho the cug
Txhim Kho Sag Kuj: HPMC txhim kho lub tshuaj khib nyiab, cia nws thov kom cov khoom siv ntsug thiab ua rau nws tsis tshua txaus ntshai.
Cov hluav taws xob cug: cov nyhuv tuab ua rau cov khoom siv ntawm cov pob tshuaj sib cais ntau dua cov khoom sib cais thiab nag lossis daus, yog li kev ua haujlwm ntawm lub cug.
3. Lubricity
HPMC muaj lubric dej zoo, uas muaj qhov cuam tshuam tseem ceeb ntawm kev tsim kho ntawm cug:
Yooj yim rau kev thov: lubricity ua cug smoother thaum thov, txo cov khoom sib tov thiab tshuaj khib thaum ua kom muaj kev nyuaj ntawm kev tsim kho.
Txo cov adhesion: lubrication tuaj yeem txo cov nplaum ntawm cultad rau cov cuab yeej siv, txo qis qhov nyuaj ntawm kev ntxuav tu, thiab txhim kho kev ua haujlwm tau zoo.
Txhim kho cov kev tsim kho: nce qhov du ntawm captness thiab txhim kho tus neeg teb xov tooj kev ua haujlwm zoo, ua daim ntawv thov ntawm lub tshuaj khib yooj yim dua.
4. Txhim kho kev tsim muaj
HPMC tseem ceeb txhim kho kev tsim kho cov kev tsim kho ntawm ntub cov tshuaj khib:
Txhim kho cov haujlwm ua haujlwm: HPMC txhim kho lub zog ntawm kev ua haujlwm ntawm cug, ua rau nws npaj tau yooj yim thiab thov thaum lub sijhawm ua haujlwm.
Kev txhim kho FLUCTION: Firmority fluentity pab cov kab cug kom zoo dua sau cov chaw tsis muaj suab thiab khoob thaum lub sijhawm kev tsim kho.
Txo cov kab ke shrinkities: txhim kho kev ua haujlwm ntawm cov tshuaj khib nyiab ntawm cov tshuaj khib thaum lub cev muaj kev sib tsoo thiab shrinkage kab noj hniav.
5. Ncua Sijhawm Qhib
HPMC tuaj yeem txuas lub sijhawm qhib ntawm cug los ntawm nws cov dej khaws cia thiab thickenies cov khoom. Cov kev ua tau zoo yog raws li hauv qab no:
Kev ua haujlwm ntev dua: hauv kev tsim kho ntev dua txhais tau tias yog lub sijhawm qhib tau qhib sijhawm siv sijhawm thiab hloov kho dua tshiab.
Txhim kho cov kev tsim kho zoo: txuas ntxiv teev sijhawm pab xyuas kom lub sijhawm tsim nyog rau kev tsim kho thaum lub sijhawm kev tsim kho, yog li kev txhim kho cov kev tsim kho txhua yam.
6. Lwm yam haujlwm
Ntxiv nrog rau cov haujlwm saum toj no, HPMC kuj muaj qee qhov kev ua haujlwm:
Nkoog-thaws kuj: HPMC tuaj yeem txhim kho lub khov-txhaj tshuaj cug yog li nws tseem tuaj yeem tswj kev ua tau zoo hauv kev muaj dej tsawg.
Txhim kho Adhesion: rau qee yam, HPMC kuj tseem tuaj yeem txhim kho cov nplaum ntawm lub tshuaj khib thiab cov khoom siv hauv paus thiab txhim kho cov nplaum ntawm lub tshuaj khib.
Txhim kho kev tawg tawm: los ntawm kev ua kom zoo dua cov kab cug, HPMC tuaj yeem txo cov kab nrib pleb thiab kub hloov pauv, thiab txhim kho cov kab cug.
HydroxyPropyyl methylcellose (HPMC) plays Lub Luag Haujlwm Tseem Ceeb hauv ntub cov tshuaj khib nyiab. Los ntawm nws lub cev thiab tshuaj lom neeg, nws ua kom cov dej ntshiab, thiab txuas ntxiv lub sijhawm qhib kev ua tau zoo thiab kev ua haujlwm zoo. Cov teebmeem no ua rau HPMC ib qho tsis tseem ceeb hauv kev ua haujlwm hauv tsev niaj hnub no thiab kev tsim kho.
