Hydroxyethyl Methyl Cellulose

HydroxyethylMethylCellulose(HEMC) kuj tseem hu ua Methyl Hydroxyethyl Cellulose (MHEC), nwsyog dawbcov methyl cellulose ether derivativesHmoov, tsis muaj ntxhiab thiab tsis muaj saj, yaj tau: yuav luag tsis yaj hauv dej kub, acetone, ethanol, ether thiab toluene. Nws yaj tau hauv dej thiab qee cov organic solvents, xws li ethanol/dej, propanol/dej, dichloroethane, hauv cov feem sib npaug. Cov tshuaj muaj kev ua haujlwm ntawm qhov chaw, pob tshab siab thiab kev ua haujlwm ruaj khov. Cov lus qhia sib txawv ntawm cov khoom muaj qhov kub gel sib txawv, uas yog cov khoom siv thermal gelling ntawm HydroxyethylMethylCellulose(HEMC). Qhov solubility hloov pauv nrog qhov viscosity. Qhov qis dua qhov viscosity, qhov ntau dua qhov solubility. Cov lus qhia sib txawv ntawm HydroxyethylMethylCellulose(HEMC)muaj qee qhov sib txawv hauv kev ua tau zoo.

Kev yaj ntawm HydroxyethylMethylCellulose(HEMC)hauv dej tsis cuam tshuam los ntawm pH. Tus nqi cuam tshuam. HydroxyethylMethylCellulose(HEMC)yog soluble nyob rau hauv dej kub, thiab yog insoluble nyob rau hauv feem ntau cov organic solvents.MethylCellulose(HEMC)Nws tawg ua tej daim me me hauv dej txias yam tsis muaj kev sib sau ua ke thiab yaj qeeb qeeb, tab sis nws tuaj yeem yaj sai sai los ntawm kev kho nws tus nqi pH rau 8 ~ 10. ph ruaj khov: qhov hloov pauv viscosity me me hauv qhov ntau ntawm ph tus nqi ntawm 2 txog 12, thiab viscosity txo qis dhau qhov ntau no.

Cov Khoom Qib

Txoj kev yaj

Ntxiv 1/3 ntawm cov dej huv uas tau teev tseg rau hauv lub thawv. Ntxiv hydroxyethyl methyl cellulose (HEMC) nyob rau hauv qhov kev sib xyaw qeeb qeeb, thiab do kom txog thaum tag nrho cov khoom siv ntub tag. Ntxiv lwm cov khoom xyaw ntawm cov mis thiab sib tov kom zoo. Muab tso rau hauv qhov ntau ntawm cov dej txias uas tau teev tseg kom txias thiab yaj.

Cov ntawv thov:

1. Cov tshuaj khib sib xyaw ua ke

Kev khaws dej ntau tuaj yeem ua rau cov cement hydrate tag nrho, ua rau lub zog sib txuas ntxiv ntau ntxiv, thiab tib lub sijhawm tuaj yeem ua rau lub zog tensile thiab lub zog shear nce ntxiv, txhim kho cov txiaj ntsig ntawm kev tsim kho thiab ua kom muaj kev ua haujlwm zoo dua.

2. Phab ntsa putty

Cov cellulose ether hauv cov hmoov putty feem ntau ua lub luag haujlwm hauv kev khaws dej, kev sib txuas thiab kev ua kom lubrication, zam kev tawg thiab lub cev qhuav dej los ntawm kev poob dej sai dhau, thiab tib lub sijhawm txhim kho qhov kev sib txuas ntawm cov putty, txo qhov tshwm sim sagging thaum lub sijhawm tsim kho, thiab ua rau kev tsim kho du.

1. Gypsum plaster

Hauv cov khoom gypsum series, cellulose ether feem ntau ua lub luag haujlwm ntawm kev khaws dej thiab ua kom lubrication ntau ntxiv. Tib lub sijhawm, nws muaj qee qhov cuam tshuam qeeb. Nws daws cov teeb meem ntawm kev nthuav tawm thiab tsis txaus lub zog pib thaum lub sijhawm tsim kho, thiab tuaj yeem ncua lub sijhawm ua haujlwm.

4. Tus neeg sawv cev sib txuas lus

Feem ntau siv ua cov khoom ua kom tuab, nws tuaj yeem txhim kho lub zog tensile thiab lub zog shear, txhim kho cov txheej txheem saum npoo, thiab txhim kho qhov adhesion thiab bonding zog.

5.Cov tshuaj nplaum rwb thaiv tsev sab nraud

Cellulose ether hauv cov khoom no feem ntau ua lub luag haujlwm ntawm kev sib txuas thiab ua kom muaj zog. Xuab zeb yuav yooj yim dua rau txheej, txhim kho kev ua haujlwm zoo, thiab muaj cov nyhuv ntawm kev tiv thaiv kev sagging. Kev ua tau zoo dua ntawm kev khaws dej tuaj yeem ntev lub sijhawm ua haujlwm ntawm cov mortar thiab ua rau muaj kev tiv thaiv. Kev tiv thaiv shrinkage thiab tawg, txhim kho qhov zoo ntawm qhov chaw, thiab ua kom muaj zog sib txuas.

6.Cov nplaum pobzeb

Qhov no ua rau cov vuas vov thiab cov hauv paus ruaj khov thiab muaj zog heev. Cov vuas vov no siv tau ntev, zoo nkauj, sib npaug zos, yooj yim rau kev tsim kho, thiab tiv taus dej thiab kev hloov pauv.

1. PobzebCov av nplaum,pob qij txhacov khoom ntim khoom

Qhov ntxiv ntawm cellulose ether ua rau nws muaj qhov zoo ntawm ntug adhesion, qis shrinkage thiab siab abrasion tsis kam, tiv thaiv cov khoom siv los ntawm kev puas tsuaj kho tshuab, thiab zam kev cuam tshuam ntawm kev nkag mus rau tag nrho lub tsev.

8.Cov khoom siv tus kheej

Qhov kev sib koom ua ke ruaj khov ntawm cellulose ether ua kom muaj kev ywj pheej zoo thiab muaj peev xwm tswj tau tus kheej, thiab tswj qhov ceev ntawm kev khaws dej kom ua rau khov sai thiab txo qhov tawg thiab ntsws.
