Yuav kom cov khoom ntawm cov mortar uas tau sib xyaw ua ke ua tau raws li qhov yuav tsum tau ua ntawm cov lus qhia thiab kev tsim kho, cov tshuaj mortar admixture yog ib qho tseem ceeb. Magnesium txhuas silicate thixotropic roj nplua nyeem thiabcellulose etherfeem ntau siv ua cov khoom ua kom dej khaws cia tuab hauv cov mortar.Cellulose ethermuaj kev khaws dej zoo, tab sis muaj ntau yam teeb meem xws li tus nqi kim, kev siv tshuaj ntau, kev nkag mus rau huab cua hnyav thiab ua rau lub zog ntawm cov mortar txo qis heev. Tus nqi ntawm magnesium txhuas silicate thixotic lubricant yog qis, tab sis kev khaws dej qis dua li ntawm cellulose ether hauv ib qho kev sib xyaw, yog li qhov ziab shrinkage tus nqi ntawm cov mortar npaj yog loj dua, thiab kev sib txuas yog txo qis.
Cov tshuaj mortar ua ntej yog cov tshuaj mortar ntub lossis cov tshuaj mortar qhuav uas tsim los ntawm cov chaw tsim khoom tshaj lij. Nws tau ua tiav kev tsim khoom lag luam, ua kom muaj kev ruaj khov ntawm qhov zoo los ntawm qhov chaw, thiab muaj ntau yam zoo xws li kev ua haujlwm zoo, tsawg dua qhov chaw ua qias tuaj, thiab txhim kho kev nce qib ntawm qhov project. Cov tshuaj mortar ua ntej (cov tshuaj mortar ntub) los ntawm qhov chaw tsim khoom mus rau qhov chaw rau kev siv, zoo li cov pob zeb ua lag luam, kev ua tau zoo ntawm nws cov kev xav tau siab dua, kom ntseeg tau tias muaj lub sijhawm ua haujlwm, lub sijhawm hauv dej tom qab sib tov, ua ntej qhov chaw teeb tsa thawj zaug kom muaj kev ua haujlwm zoo txaus, tuaj yeem ua tiav kev tsim kho thiab kev ua haujlwm ib txwm muaj.
Qhov cuam tshuam ntawm kev sib xyaw ua ke ntawm magnesium txhuas silicate thixotropic lubricant thiabcellulose etherntawm qhov sib xws, delamination, teeb tsa lub sijhawm, lub zog thiab lwm yam khoom ntawm pre-mixed (ntub sib xyaw) mortar yog raws li nram no:
01
Cov mortar uas ua tiav yam tsis muaj cov tshuaj thickener uas khaws dej tau muaj zog heev, tab sis nws tsis khaws dej tau zoo, tsis sib haum, tsis mos, thiab tsis ntws dej ntau, tsis zoo rau kev tuav, thiab yeej siv tsis tau. Yog li ntawd, cov khoom siv thickener uas khaws dej tau yog ib qho tseem ceeb ntawm cov mortar uas twb sib tov lawm.
02
Thaum cov magnesium txhuas silicate thixotropic roj nplua nyeem thiab cellulose ether sib xyaw ua ke, kev ua tau zoo ntawm cov mortar tau zoo dua piv rau cov mortar dawb paug, tab sis kuj muaj qee qhov tsis zoo. Thaum ntxiv magnesium txhuas silicate thixotropic roj nplua nyeem, qhov ntau ntawm magnesium txhuas silicate thixotropic roj nplua nyeem muaj feem cuam tshuam loj rau kev siv dej, thiab kev khaws dej qis dua li cellulose ether. Thaum cellulose ether sib xyaw nrog cellulose ether, cov mortar muaj kev ua haujlwm zoo dua, tab sis thaum cov ntsiab lus ntawm cellulose ether siab, lub zog ntawm cov mortar raug txo qis heev, thiab tus nqi kim heev, uas ua rau tus nqi khoom siv nce mus rau qee qhov.
03
Nyob rau hauv qhov xwm txheej ntawm kev ua kom cov mortar ua tau zoo hauv txhua yam, qhov koob tshuaj zoo tshaj plaws ntawm magnesium txhuas silicate thixothixotic lubricant yog li 0.3%, thiab qhov koob tshuaj zoo tshaj plaws ntawm cellulose ether yog 0.1%. Qhov koob tshuaj ntawm ob qho sib xyaw yog tswj hwm hauv qhov sib piv no, thiab cov txiaj ntsig zoo.
04
Cov tshuaj khib uas tau npaj los ntawm kev sib xyaw ua ke ntawm magnesium txhuas silicate thixotropic lubricant thiab cellulose ether muaj kev ua haujlwm zoo, kev sib xws thiab kev poob, kev sib cais, lub zog compressive thiab lwm yam kev ua tau zoo tuaj yeem ua tau raws li qhov yuav tsum tau ua thiab kev tsim kho.
Kev faib tawm thiab kev qhia luv luv ntawm mortar
Cov tshuaj khib feem ntau muab faib ua cov tshuaj khib ib txwm thiab cov tshuaj khib tshwj xeeb ob pawg.
(1) cov av qhuav ib txwm muaj
