Inorganic Cementing Cov Khoom Siv Hauv Drymix Mortar

Inorganic cementing cov ntaub ntawv yog ib qho tseem ceeb ntawm drymix mortar, muab cov khoom tsim nyog los tuav lwm cov khoom ua ke. Nov yog qee cov khoom siv uas tsis muaj tshuaj lom neeg siv hauv cov tshuaj khib nyiab qhuav:

1. Portland MAAs: Portland cement yog cov cement feem ntau siv hauv cov tshuaj khib nyiab qhuav. Nws yog cov hmoov zoo uas yog tsim los ntawm cua sov limestone thiab lwm yam ntaub ntawv kom kub kub hauv ib lub kiln. Thaum sib tov nrog dej, Portland cement tsim ib qho tshuaj txhuam uas ua kom tawv thiab khi rau lwm cov khoom ntawm cov mortar ua ke.
2. Calcium aluminate MAAs: Calcium aluminate MAAs yog ib hom cement ua los ntawm bauxite thiab limestone uas yog siv rau hauv tshwj xeeb drymix mortars, xws li cov siv rau refractory daim ntaub ntawv. Nws paub txog nws lub sijhawm teem ceev thiab lub zog siab.
3. Slag MAAs: Slag MAAs yog ib qho khoom siv los ntawm kev lag luam steel thiab yog hom cement ua los ntawm kev sib xyaw hauv av granulated blast furnace slag nrog Portland cement. Nws yog siv nyob rau hauv drymix mortar los txo tus nqi ntawm Portland cement xav tau thiab los txhim kho kev ua hauj lwm thiab durability ntawm mortar.
4. Hydraulic txiv qaub: Hydraulic txiv qaub yog ib hom txiv qaub uas teeb thiab tawv thaum raug dej. Nws yog siv nyob rau hauv qhuav mix mortar raws li ib tug binder rau restoration ua hauj lwm thiab rau masonry kev tsim kho qhov twg ib tug softer, ntau saj zawg zog mortar yog xav tau.
5. Gypsum plaster: Gypsum plaster yog ib hom plaster ua los ntawm gypsum, ib qho ntxhia mos uas feem ntau siv hauv cov tshuaj khib nyiab rau sab hauv phab ntsa thiab qab nthab. Nws yog tov nrog dej los tsim ib tug muab tshuaj txhuam uas hardens sai sai thiab muab ib tug du nto.
6. Quicklime : Quicklime yog ib yam khoom uas muaj zog heev, uas yog tsim los ntawm cov cua kub limestone rau qhov kub thiab txias. Nws yog siv nyob rau hauv tshwj xeeb drymix mortars, xws li cov siv rau keeb kwm preservation thiab restoration ua hauj lwm.

Zuag qhia tag nrho, kev xaiv ntawm cov khoom siv hauv cov khoom siv cementing hauv cov tshuaj khib nyiab yog nyob ntawm daim ntawv thov tshwj xeeb thiab cov khoom xav tau ntawm cov khoom kawg. Kev sib xyaw ua ke ntawm cov ntaub ntawv cementing tuaj yeem muab qhov tsim nyog lub zog, ua haujlwm ntev, thiab ua haujlwm tau zoo uas yuav tsum tau ua rau ntau yam kev tsim kho.
