MHEC LH 640 M

EipponCell MHEC LH 640M, uas yog methyl hydroxyethyl cellulose, feem ntau yog siv hauv cov tshuaj khib nyiab qhuav.Nov yog cov lus piav qhia ntawm cov ntsiab lus tseem ceeb uas tau hais hauv nqe lus:

Kev tuav dej zoo: MHEC ua kom cov mortar khaws cov dej txaus, tiv thaiv cov teeb meem xws li xuab zeb, hmoov av, thiab txo lub zog los ntawm dej tsis txaus thiab cov cement hydration tsis tiav.Nws txhim kho cov uniformity, workability, thiab hardening ntawm cov khoom.Raws li tus nqi ntawm MHEC ntxiv nce, cov txiaj ntsig kev ntxhov siab thiab frown viscosity ntawm mortar kuj nce.

Air-entraining agent: MHEC tuaj yeem ua haujlwm raws li tus neeg saib xyuas huab cua.Cov huab cua siab tshaj plaws nyob rau hauv mortar yog ua tiav thaum MHEC tus nqi yog 0.5%.Txawm li cas los xij, thaum cov nyiaj ntau tshaj 0.5%, cov ntsiab lus ntawm huab cua maj mam txo, ua rau txo qis zog thiab compressive zog.

Txhim kho kev ua haujlwm: Qhov sib ntxiv ntawm MHEC ua kom yooj yim rau daim ntawv thov ntawm cov txheej nyias nyias thiab plastering mortar.MHEC ncua kev hydration ntawm mortar hais, thiab qhov degree ntawm kev hloov (DS) plays lub luag hauj lwm tseem ceeb nyob rau hauv no ncua hydration txheej txheem.Qhov cuam tshuam ntawm methoxyl cov ntsiab lus ntawm kev ncua hydration yog qhov tseem ceeb tshaj li cov ntsiab lus ntawm hydroxyethyl.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cellulose ether muaj ob qho kev cuam tshuam rau kev ua haujlwm mortar.Nws cov txiaj ntsig yog nyob ntawm kev siv tsim nyog;Kev siv tsis raug tuaj yeem muaj qhov tsis zoo.Kev ua tau zoo ntawm cov tshuaj khib nyiab qhuav yog cuam tshuam los ntawm cov khoom xws li kev sib raug zoo ntawm cellulose ether thiab tus nqi thiab qhov sib npaug ntawm qhov sib ntxiv.Hauv kev siv tswv yim, ib hom cellulose ether tuaj yeem xaiv, lossis ntau hom tuaj yeem siv ua ke.
