HPMC (HydroxyPropyyl methylulose) yog cov tshuaj siv cov tshuaj tua neeg siv hauv kev tsim kho kev tsim kho, tshwj xeeb tshaj yog nyob rau hauv cov neeg nplua neeg. Raws li cov tuab tuab heev, cov dej-khaws cov neeg sawv cev thiab cov yeeb yaj kiab-ua yeeb yam kev tsim kho ntawm cug thiab qhov kawg ua haujlwm zoo.
1. Txhim kho cov dej ceev ceev ntawm cug
Ib qho haujlwm tseem ceeb ntawm HPMC yog txhawm rau txhim kho cov dej ceev ntawm cug. Dej ceev ceev yog hais txog cug lub peev xwm los khaws cov dej noo thaum lub teeb tsa kev teeb tsa, uas yog qhov tseem ceeb rau kev ua kom muaj zog ntawm lub cug. Kev xaiv cov ntoo txau ua rau kev kho tsis ncaj thiab tawg vim yog cov dej noo sai. Tom qab ntxiv HPMC, cov dej hauv lub tshuaj tua hluav taws xob tuaj yeem faib tau ntau dua thiab khaws cia hauv cov khoom siv hluav taws xob nrawm. Nyob rau hauv txoj kev no, tsis tsuas yog lub zog ntawm lub cug cug yog txhim kho, tab sis kuj tawg tshwm los ntawm kev ziab ntxov ntxov yog zam.
2. Txhim khu kev ua haujlwm ntawm cug
HPMC muaj cov nyhuv zoo heev thiab tuaj yeem txhim kho kev tsim kho kev tsim kho ntawm cug. HPMC tuaj yeem ua lub tshuaj khib tau txais cov viscosity uas tsim nyog, ua rau nws smoother thaum lub sijhawm sib xyaw, kis las thiab theem teeb meem ntawm kev tsim kho. Qhov nce viscosity ntawm lub tshuaj khib nyiab pab txhim kho nws cov nplaum kom lub substrate thiab tiv thaiv kev tshuaj khib ntawm zawv zawg lossis poob tawm. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv kev tsim kho ntawm cov phab ntsa ntsug, raws li kev tshuaj tsuag yuav tsum ua kom zoo rau phab ntsa yam tsis muaj kev soagging.
3. Txhim kho cov sag kam ua cug
HPMC tseem tuaj yeem txhim kho nws cov sag tsis kam ua kab tshuaj khib, tshwj xeeb tshaj yog thaum ua tiav txheej tuab. Yog hais tias lub tshuaj khib kev yooj yim thaum kev tsim kho, nws yuav ua rau qhov txo qis hauv kev tsim kho, tsis sib xws, thiab txawm tias qhov xav tau rov tsim kho. Lub thickening nyhuv ntawm HPMC tuaj yeem zam qhov teeb meem no, ua kom cov tshuaj khib nyiab ntau ruaj khov thaum tsim cov duab ntsug thiab kev tswj hwm cov duab kom muaj thiab tuab.
4. Txhim kho qhov ua haujlwm ntawm cug
Kev ua haujlwm ua haujlwm yog hais txog kev ua kom sib xyaw ua haujlwm thiab kev tsim kho kev tshuaj khib. HPMC hloov kho qhov xwm yeem, kev plam thiab fluicity ntawm cug nrawm dua li kev sib xyaw thiab siv, yog li txhim kho qhov yooj yim ntawm kev tsim kho. Kev ua haujlwm zoo tsis tuaj yeem tsuas yog nce cov kev tsim kho, tab sis kuj ua kom pom tseeb kom tsis txhob muaj culture lossis dhau lawm, yog li kev txhim kho cov khoom siv ua tau zoo.
5. Ncua Sijhawm Qhib
Lub sijhawm qhib yog hais txog lub sijhawm tshuaj khib tseem ua haujlwm nyob thaum kev tsim kho. HPMC tuaj yeem txuas lub sijhawm qhib kev tshuaj khib los ntawm kev txhim kho nws cov dej khaws cia thiab ncua dej evaporation. Kev siv cov xuab moos qhib muab cov neeg tsim kho nrog ntau lub sijhawm rau kev kho kom haum thiab kho kom raug rau kev ua yuam kev. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv kev tsim kho loj-thaj chaw lossis nyuaj-tsim qauv, uas tuaj yeem ua kom cov txheej txheem kev tsim kho ntawm cov txheej txheem kev tsim kho thiab txhim kho cov kev tsim kho tag nrho.
6. Txhim kho kev tawg
Txij li thaum HPMC tuaj yeem txhim kho cov dej rov qab los ntawm cug thiab ua kom cov xis mas hydrated, tag nrho cov kev ua tau zoo ntawm lub tshuaj khib tau txhim kho. Tshwj xeeb tshaj yog nyob rau hauv qhuav ib puag ncig, dej so zog ntawm cug cug yog qhov tseem ceeb. HPMC tuaj yeem tiv thaiv lub tshuaj khib los ntawm cov dej ntws tawm dhau los, yog li cuam tshuam qhov tawg ntawm cov tshuaj khib. Cov kev tawg ua tau zoo tseem ceeb yog qhov tseem ceeb rau lub sijhawm ntev divility thiab zoo nkauj ntawm lub tsev.
7. Kev tiv thaiv ib puag ncig thiab kev lag luam
HPMC nws tus kheej yog cov tshuaj tsis muaj tshuaj lom thiab tsis muaj zog uas yuav tsis ua rau muaj kuab paug thiab ua tau raws li cov ntaub ntawv tsim kho niaj hnub no. Tsis tas li ntawd, kev sib ntxiv ntawm HPMC tuaj yeem txo cov dej haus thiab txoj hlab cug, yog li txo tus nqi siv. Kev tsim kho siab dua thiab cov khoom kawg zoo dua kuj txhais tau tias Manpower cov txiaj ntsig tuaj yeem raug cawm tau, nrog cov txiaj ntsig kev lag luam ntau dua.
8. Dav yooj yim
HPMC yog tsim nyog rau ntau hom kev nplua nuj, xws li plastering cug, kev sib raug zoo, tus kheej cuam tshuam los ntawm lwm qhov kub thiab txias thiab av noo. Qhov no ua rau HPMC cov cuab yeej siv dav dav dav tsev ntxiv thoob ntiaj teb.
Daim ntawv thov ntawm HPMC hauv kev tsim kho lub tshuaj khib nyiab tau txhim kho cov tshuaj khib, suav nrog cov dej cia, ua haujlwm, tawg tsis taus thiab kav ntev. Los ntawm kev siv HPMC, cov neeg ua haujlwm tsim kho tuaj yeem tau txais kev ua haujlwm zoo dua thiab cov khoom lag luam zoo tag nrho tuaj yeem lav tau zoo. Ib qho ntxiv, HPMC ib puag ncig kev tiv thaiv thiab kev lag luam ntxiv txhim kho nws daim ntawv thov tus nqi hauv kev tsim kho. Nrog kev txhim kho kev txuas ntxiv ntawm kev tsim kho thev naus laus zis, kev thov cov kev cia siab ntawm HPMC hauv cug yuav ua rau dav.
