Kev ntsuas ntawm cov txheej txheej yog hais txog lub peev xwm ntawm txheej kom sib kis tusyees thiab maj mam tom qab txheej, thiab kom tshem tawm cov cim saum npoo xws li txhuam cov cim thiab cov cim yob. Leveling ncaj qha cuam tshuam cov tsos, tiaj thiab zoo ntawm txheej zaj duab xis, yog li nyob rau hauv txheej txheej txheej txheej, optimizemy leveling yog qhov tseem ceeb heev.HydroxyPropyyl methylcellulose (HPMC), raws li cov dej tseem ceeb-ua cov thickener thiab zaj duab xis-ua kev pab, yog siv dav hauv cov txheej txheej. Nws tsis tuaj yeem kho cov viscosity ntawm txheej, tab sis kuj txhim kho kev txhim kho theem ntawm txheej.
1. Cov khoom thiab cov haujlwm ntawm hydroxypropy kasthylcellose
HydroxyPropyyl methylulose yog dej-soluble polymer compound tau los ntawm kev hloov tshuaj lom neeg nrog cov khoom siv ntawm cellulose. Nws cov qauv molecular muaj cov pab pawg hydrophilic (xws li cov pab pawg hydroxyl thiab cov pab pawg hydrophobic (uas ua rau nws muaj cov dej solubility thiab dispersibility. Vim nws cov viscosity siab, cov khoom siv ua kom zoo xws li cov xim av zoo xws li cov xim looj dej zoo li cov xim looj cov xim tsev, kos duab kos duab, thiab lwm yam.
Hauv cov tsho tiv no, HPMC, raws li cov tuab dua, tuaj yeem nce viscosity ntawm txheej, kho cov rheology ntawm txheej, thiab ua kom pom kev vam meej thaum lub sijhawm txheej txheej. Tshwj xeeb, HPMC tuaj yeem txhim kho cov xim dej ntawm txheej thiab txo cov txheej txheem sib dhos ntawm cov txheej txheem thiab tshem tawm cov khoom tsis ncaj ncees xws li txhuam cov cim thiab cov cim yob.
2. Mechanism ntawm hydroxypropyl methylcelulose los txhim kho cov theem ntawm txheej txheej
Kho lub viscosity thiab rheology ntawm txheej
HydroxyPropyyl methylculose nce viscosity ntawm txheej txheej, tsis txhob sib los ntawm cov txheej txheem txheej txheej nrawm, ua rau cov cim tsis xwm dhau, ua rau cov cim tsis xwm yeem ntawm cov txheej duab txheej. Qhov tsim nyog viscosity tuaj yeem ua rau txheej txheem ntau tusyees faib rau thaum txheej, txo cov kev hloov pauv hauv qhov ntws ntawm txheej, thiab yog li txhim kho theem.
Txo cov npoo nruj ntawm txheej
Tom qab dissolving nyob rau hauv cov txheej, hydroxypropyl methylcellulose tuaj yeem txo cov nro ntawm cov txheej. Kev txo qis hauv cov txheej nro yuav ua tau cov txheej txheej ua cov kua txiv ntau dua ntawm cov txheej txheem tsis sib xws los ntawm cov txheej tsis sib xws los ntawm kev nruj sib txawv. Nyob rau tib lub sijhawm, qis dua saum npoo
Txhim kho fluidity ntawm txheej xim zaj duab xis
Cov molecular chains ntawm Kimacell® tus qauv yuav cuam tshuam nrog cov txheej txheem mees, zam kev tawg lossis tsis sib luag vim yog kev ziab khaub ncaws heev. Nws tseem tuaj yeem siv hluav taws xob thaum lub sijhawm txheej txheej txheej txheej kom ntseeg tau tias cov txheej txheem sib dhos.
Pluas cov nyhuv
Cov qauv molecular ntawm hydroxypropylulose muaj qee pab pawg hydroughilic, uas tuaj yeem tsim cov lwg dej, yog li txhim kho cov wettability ntawm txheej. Cov nyhuv ntub no pab txhawm rau txhim kho cov nplaum ntawm cov txheej txheem thiab cov ntug dej ntau, thiab tseem txhim kho cov txheej txheej theem, ua cov xim yeeb yaj kiab smoother thiab smoother.
Txhim kho tus neeg evaporation ntawm txheej
Thaum lub sijhawm ua kom qhuav ntawm txheej, HPMC tuaj yeem tswj txoj cai ntawm evaporation tus nqi. Los ntawm maj mam tso dej, HPMC pab kom lub sijhawm khiav tawm ntev dua thaum lub sijhawm txheej txheem ntawm kev ua kom qhuav ntawm cov txheej txheej kom qhuav ntawm cov txheej txheej.
3. Daim ntawv thov ntawm hydroxypropyl methylcellose hauv cov txheej txheej
Cov dej pleev dej ua ke
Hauv cov txheej txheem dej-ua cov txheej txheem dej, HPMC tuaj yeem siv los ua cov tuab tuab los txhim kho txheej txheej thiab qib leveling. Tshwj xeeb tshaj yog nyob rau hauv txheej txheej uas yuav tsum tau siv sijhawm qhib sijhawm ntev, lub luag haujlwm ntawm HPMC yog qhov tshwj xeeb. Nws tuaj yeem txhim kho cov kua txiv ntoo ntawm cov txheej, tsis txhob txhuam cov cim thiab kab ntawm txheej, thiab xyuas kom cov txheej du ntawm txheej.
Txheej Txheem Architural
Rau cov kws ua yeeb yam Architectural, HPMC tsis yog pab txhawb theem ntawm txheej txheej, tab sis kuj muaj cov dej noo kom zoo nyob ruaj khov thiab txhim kho qhov yooj ntawm cov yeeb yaj kiab txheej. Thaum lub sij hawm tsim qauv txheej txheem kos duab, HPMC tuaj yeem txhim kho cov nplaum thiab kev tawm tsam ntawm cov txheej thiab nce lub durability ntawm txheej xim zaj duab xis.
High-txhais lub tsho tiv no
Siab ci ntsa iab pleev xim yuav tsum tau zoo heev nto li ua tiav thiab theem. HPMC tuaj yeem tshem tawm cov xwm txheej saum npoo av thaum tsim kho kom zoo nkauj ntawm cov txheej thiab txuas ntxiv qhib lub sijhawm, ua kom lub ntsej muag qhib ntawm cov txheej.
Lub Tsheb Hlau Txheej Hlau
Automotive txheej yuav tsum tau glight thiab tiaj. HPMC tuaj yeem txhim kho kev txhawb nqa theem ntawm txheej, txo cov npuas, txhuam cov khoom thiab lwm yam tsis xws luag, thiab xyuas kom zoo thiab pom ntawm txheej.
4. Kev ceev faj thiab cov nyom hauv kev siv
Txawm yogHPMCMuaj peev xwm txhim kho kev ntsuas ntawm cov txheej txheej ntawm txheej, muaj qee qhov kev ceev faj rau nws siv hauv cov txheej txheej. Ua ntej, kev pom zoo ntawm Kimacell®hpmc yuav tsum tau hloov kho raws li hom, mis thiab siv cov kev xav tau ntawm cov txheej txheem. Siab heev lub siab yuav ua rau cov xim ntawm cov txheej kom tsawg, uas yuav cuam tshuam kev ua haujlwm. Thib ob, tus nqi HPMC ntxiv yuav tsum tau siv rau hauv cov nyiaj ntawm lwm cov kev sib ntxiv thiab cov pigments. Kev ntxiv ntau zaus yuav ua rau lwm cov khoom ntawm cov txheej txheej kom txo qis, xws li hardness thiab dej tsis kam. Yog li no, kev xaiv tsim nyog thiab kev sib deev ntawm HPMC yog tus yuam sij los ua kom muaj kev ua tau zoo ntawm cov txheej txheem.
HydroxyPropy muag yuav ua tau zoo ntxiv txhim kho kev ua kom nruj ntawm cov txheej txheem sib txawv, thiab txhim kho cov txheej txheem txheej txheem thiab txhim kho cov tsos zoo ntawm cov yeeb yaj kiab txheej. Nrog rau qhov kev thov nce siab ntxiv rau kev ua haujlwm hnyav dej-ua cov txheej txheem hauv kev lag luam txheej txheej HPMC yuav txuas ntxiv mus ntxiv. Raws li ib qho kev txhawb nqa tau zoo ntxiv, nws yuav twv yuav raug hu ua ib qho qauv txheej txheem yav tom ntej.
