Daim ntawv thov ntawm Instant HydroxyPropylropylulose etherylcellulose etherfaging cug kev ua haujlwm, txhim kho kev tsim kho tshuaj txig, txhim kho kev tsim kho. HPMC yog cov polymer sib txuas nrog cov dej solubility thiab zoo nkauj nplaum, thiab yog dav siv hauv kev tsim kho, tshuaj, tshuaj thiab lwm thaj chaw. Nws daim ntawv thov hauv cov neeg kho tshuab cov tshuaj collport, tiv thaiv kev ua kom zoo nkauj, ua lub zog tsim kho thiab zoo tshaj plaws ntawm lub cug.
1. Cov khoom yooj yim ntawm Instant Hydroxypropyl methylcelulose ether
HPMC yog dej-soluble polymer tau los ntawm cov tshuaj cellulose ntawm ntuj, nrog cov khoom siv ua yeeb yaj kiab zoo, ua yeeb yaj kiab ua yeeb yaj kiab thiab thickening cov khoom. Cov dej ua yeeb yaj kiab ntawm HPMC ua rau nws tau nrawm dua hauv cov teeb meem tsim kho kom tsis tiav ntawm cov tshuaj khib nyiab hauv lub tshuaj khib. Tsis tas li ntawd, HPMC muaj cov dej ua kom zoo thiab muaj peev xwm ncua cov dej evaporation, uas yog qhov tseem ceeb los txhim kho cov nplaum thiab tawg ntawm cov tshuaj khib.
2. Lub luag haujlwm ntawm HPMC hauv cov neeg kho tshuab cov tshuaj txig cug
(1) Txhim kho cov fluidity thiab kev tsim kho
Mechanical spreat colrvolt feem ntau feem ntau yuav tsum muaj cov fluidity zoo nyob rau hauv thiaj li yuav tau txau cov khoom siv txau kom huv ntawm cov khoom txau. HPMC muaj cov nyhuv zoo heev thiab tuaj yeem tsim cov qauv colloidal ruaj khov hauv lub tshuaj khib, yog li txhim kho fellitity ntawm lub tshuaj khib. Los ntawm kev kho cov tshuaj hpmc, volmosity ntawm cug tshuaj yuav ua kom yooj yim rau sag lossis khom thaum lub sij hawm txau txheej txheem, yog li ua kom muaj kev ruaj ntseg ntawm kev tsim kho.
(2) Txhim Kho Cov Dej Ua Haujlwm
Dej khaws cia yog ib qho khoom tseem ceeb hauv cov neeg kho tshuab kab tshuaj cug, kom qhuav nrawm thiab tawg ntawm cug. HPMC muaj cov dej ua tau zoo heev thiab tuaj yeem tiv thaiv dej los ntawm kev ua kom sai sai, yog li tsis txhob muaj teeb meem xws li kev tawg thiab poob tawm ntawm lub cug lub sij hawm siv. HPMC tuaj yeem pab cov tshuaj khib kom tsim nyog noo thaum lub tshuab ziab khaub ncaws, yog li ua kom tiav nrog lub substrate thaum lub sij hawm kho.
(3) adjected segration tiv thaiv
Hais tawm hauv cov tshuaj khib yuav ua rau lub sijhawm luv luv lossis tshuaj tsuag, uas yog, cov khoom siv hluav taws xob tsis sib thooj. HPMC tuaj yeem txhim kho kev tshuaj khib sab hauv, txhim kho lub collegation tiv, thiab zam cov particle sedimentation, yog li tswj cov kev sib xws thiab ruaj khov ntawm lub cug. Nyob rau hauv txoj kev no, ntau yam ntawm cov tshuaj khib nyiab tau ceev cia kom zoo raws li thaum lub sij hawm txau txheej txheem, kom ua rau cov khoom lag luam zoo.
(4) Txhim Kho Lub Zog
Daim Ntawv Cog Lus yog qhov taw qhia tseem ceeb rau kev ntsuas qhov zoo ntawm cov neeg kho tshuab ntub cug. HPMC tuaj yeem txhim kho txoj kev sib raug zoo ntawm cug thiab substrate los ntawm nws qhov zoo tshaj plaws dispersibility thiab adsorption. Cov tshuaj yeeb tshuaj colloidal tsim los ntawm HPMC hauv tshuaj khib tau txhim kho kev tshuaj khib nyiab thiab txhim kho txoj kev tshuaj khib nyiab thiab txhim kho txoj kev tshuaj khib nyiab thiab txhim kho lub zog compressive thiab tawg tsis kam tom qab kev tsim kho.
3. Daim ntawv thov nyhuv ntawm HPMC hauv cov neeg kho tshuab cov tshuaj txig cug
Los ntawm kev sim tshawb fawb thiab kev ua engineering, nws pom tias daim ntawv thov ntawm HPMC hauv cov khoom tsuag tsuag tau txhim kho ntau yam khoom ntawm cug. Thaum lub sij hawm txau txheej txheem, cov dej ua kom huv, dej ua kom tsis txhob muaj zog, cais lub zog ntawm lub tshuaj khib yog hloov kho. Piv txwv li, hauv kev tshuaj khib nyiab siv HPMC, cov nplaim yog smoother tom qab tshuaj tsuag, ua haujlwm ua haujlwm tau siab dua, thiab cov neeg ua haujlwm tsim kho tau yooj yim dua.
Lub luag haujlwm ntawm HPMC hauv kev txhim kho cov tshuaj cug zoo tau tseem tau pom dav dav. Hauv cov kws ua engineering nrog kev ua haujlwm siab xws li kev ua haujlwm hnyav, tawg ua kom zoo dua qub ntawm lub tshuaj khib thiab ua kom cov kev tsim kho zoo thiab ua kom tau zoo.
4. Kev ceev faj rau kev siv HPMC hauv cov neeg kho tshuab cov tshuaj tsuag cug
Txawm hais tias daim ntawv thov nyhuv ntawm HPMC hauv cov neeg kho tshuab Cov tshuaj khib yog qhov tseem ceeb, cov ntsiab lus hauv qab no yuav tsum tau sau tseg thaum siv tau:
Kev tswj ntau tshuaj tswj: cov tshuaj ntawm HPMC yuav tsum tau hloov kho raws li cov kev xav tau tiag tiag. Kev siv ntau dhau yuav ua rau lub tshuaj khib kom ua tau zoo thiab cuam tshuam cov nyhuv kev tsim kho; Ntau dhau noj tshuaj yuav tsis ua tiav nws cov thickening, dej khaws cia thiab lwm yam haujlwm.
Dispersility: HPMC yuav tsum tau ua txhua yam tawg rau hauv lub tshuaj khib nyiab kom tsis txhob muaj cov txuj ci hauv zos vim tsis muaj kev sib cais. Nws feem ntau pom zoo kom yaj HPMC ua ntej lossis sib tov nws nrog lwm cov ntaub ntawv los txhim kho nws qhov kev tawg.
Sib txuam nrog lwm tus admixtures: hauv cov tshuab tshuaj txau cug cug
Raws li lub tsev tseem ceeb ntxiv, tam sim no hydroxypropyl minetherleculeculose ether muaj dav thov tshuaj khib cug. Nws tuaj yeem txhim kho kom muaj kua dej, tiv thaiv kev tiv thaiv thiab lub zog tsim kho ntawm lub tshuaj khib, tab sis kuj tseem txhim kho qhov zoo tagnrho ntawm txoj haujlwm. Nrog kev txhim kho kev ua lag luam tas mus li, daim ntawv thov HPMC hauv kev txhim kho cov ntaub ntawv hauv tsev yuav ua kom muaj kev txhim kho kev ua haujlwm zoo thiab kev ua haujlwm zoo hauv kev tsim kho.
