Hydroxyethyl Methyl Cellulose
HydroxyethylMethylCelulose(HEMC) kuj muaj npe hu ua Methyl Hydroxyethyl Cellulose (MHEC), nwsyog dawbmethyl cellulose ether derivativeshmoov, tsw thiab saj, soluble: yuav luag insoluble hauv dej kub, acetone, ethanol, ether thiab toluene. Nws yog soluble hauv dej thiab qee cov kuab tshuaj organic, xws li ethanol / dej, propanol / dej, dichloroethane, hauv qhov tsim nyog proportions. Cov tshuaj muaj qhov ua haujlwm saum npoo, siab pob tshab thiab kev ua haujlwm ruaj khov. Cov khoom sib txawv ntawm cov khoom muaj qhov sib txawv gel kub, uas yog cov thermal gelling zog ntawm HydroxyethylMethylCelulose(HEMC). Lub solubility hloov nrog viscosity. Qhov qis dua qhov viscosity, qhov ntau dua qhov solubility. Txawv specifications ntawm HydroxyethylMethylCelulose(HEMC)muaj qee qhov sib txawv hauv kev ua haujlwm.
Lub dissolution ntawm HydroxyethylMethylCelulose(HEMC)hauv dej tsis cuam tshuam los ntawm pH. Tus nqi cuam tshuam. HydroxyethylMethylCelulose(HEMC)yog soluble hauv dej kub, thiab yog insoluble nyob rau hauv feem ntau cov organic solvents. Nto kho HydroxyethylMethylCelulose(HEMC)disperses nyob rau hauv dej txias yam tsis agglomerating thiab yaj maj mam, tab sis nws yuav sai sai yaj los ntawm kev kho nws tus nqi pH rau 8 ~ 10. ph stability: qhov viscosity hloov me me nyob rau hauv thaj tsam ntawm ph nqi los ntawm 2 mus rau 12, thiab viscosity txo qis tshaj qhov no.

Txoj kev tawg
Ntxiv 1/3 ntawm cov dej huv uas tau teev tseg rau hauv lub thawv. Ntxiv hydroxyethyl methyl cellulose (HEMC) nyob rau hauv qis-ceev stirring, thiab do kom txog thaum tag nrho cov ntaub ntawv yog kiag li ntub. Ntxiv lwm cov khoom xyaw ntawm cov mis thiab sib tov zoo. Txuas mus rau qhov teev cov dej txias kom txias thiab yaj.
Daim ntawv thov:
1.Dry mix mortar
Kev tuav dej siab tuaj yeem ua kom muaj dej txaus rau cov cement, ua kom lub zog sib txuas, thiab tib lub sijhawm tuaj yeem tsim nyog ua kom lub zog tensile thiab shear zog, zoo heev txhim kho kev tsim kho thiab ua kom muaj kev ua haujlwm zoo.
2. Phab ntsa putty
Lub cellulose ether nyob rau hauv cov hmoov putty feem ntau plays lub luag hauj lwm nyob rau hauv dej tuav, kev sib txuas thiab lubrication, tsis txhob tawg thiab lub cev qhuav dej los ntawm cov dej ceev heev, thiab nyob rau tib lub sij hawm txhim khu lub adhesion ntawm lub putty, txo cov sagging tshwm sim thaum lub sij hawm tsim kho, thiab ua kom kev tsim kho smoother.
- Gypsum plaster
Hauv cov khoom lag luam gypsum, cov cellulose ether tsuas yog ua lub luag haujlwm ntawm khaws cov dej thiab ua kom muaj roj. Nyob rau tib lub sijhawm, nws muaj qee yam kev cuam tshuam. Nws daws cov teeb meem ntawm bulging tawm thiab tsis muaj zog pib thaum lub sij hawm tsim kho, thiab tuaj yeem txuas ntxiv lub sijhawm ua haujlwm.
4.Interface tus neeg saib xyuas
Feem ntau yog siv los ua cov thickener, nws tuaj yeem txhim kho lub zog tensile thiab shear lub zog, txhim kho cov txheej txheej saum npoo, thiab txhim kho cov adhesion thiab kev sib txuas lub zog.
5.Sab nraud thermal rwb thaiv tsev mortar
Cellulose ether nyob rau hauv cov khoom no feem ntau plays lub luag hauj lwm ntawm kev sib txuas thiab ua kom lub zog. Xuab zeb yuav yooj yim rau lub tsho tiv no, txhim kho kev ua haujlwm ntawm kev ua haujlwm, thiab muaj cov nyhuv los tiv thaiv sagging. Kev tuav dej ntau dua tuaj yeem txuas ntxiv lub sijhawm ua haujlwm ntawm cov mortar thiab ua rau kom muaj zog. Shrinkage thiab tawg tsis kam, txhim kho nto zoo, thiab ua kom muaj zog sib txuas.
6.Pobzeb Adhesive
Kev tuav dej siab tshem tawm qhov xav tau los ntub dej ua ntej lossis ntub cov vuas thiab cov hauv paus, txhim kho lawv txoj kev sib raug zoo. Lub slurry tuaj yeem tsim nrog lub sijhawm ntev, kev ua kom zoo, sib xws, kev tsim kho yooj yim, thiab ua haujlwm zoo rau ntub dej thiab tsiv teb tsaws.
