Kev siv sib txawv ntawm cov hmoov qhuav mortar additives!

1. Redispersible latex hmoov

Cov khoom siv dej hauv qhov ncauj no yog ib qho tshwj xeeb siab molecular polymer, uas yog tsim los ua hmoov tom qab ziab kom qhuav.Tom qab sib cuag nrog dej, cov hmoov no tuaj yeem ua ib qho emulsion dua, thiab muaj cov khoom zoo ib yam li emulsion.Tom qab cov dej evaporates, nws tuaj yeem tsim ib zaj duab xis.Cov yeeb yaj kiab muaj qhov hloov tau yooj yim, huab cua tsis kam, thiab nthuav tawm siab adhesion rau ntau yam substrates.

Yog li ntawd, nws yog ib qho tseem ceeb raw khoom nyob rau hauv qhuav-mixed mortar, uas yuav txhim kho kev ua tau zoo, nce lub zog, txhim kho cov adhesion ntawm qhuav hmoov mortar rau ntau yam substrates, txhim kho qhov yooj, compressive zog, thiab hnav tsis kam ntawm qhuav hmoov mortar.Tsis tas li ntawd, Yog hais tias nws yog tov nrog hydrophobic latex hmoov, nws muaj peev xwm ua rau cov hmoov qhuav mortar waterproof.

2. Cellulose

Cellulose nrog viscosities sib txawv muaj kev siv sib txawv.Cellulose tuaj yeem siv rau hauv cov hmoov qis qis rau cov phab ntsa sab hauv, uas tuaj yeem ua kom cov dej tuav thiab nce qib.Nws yog tshuaj lom neeg ruaj khov, tuaj yeem tiv thaiv mildew, muaj dej tuav zoo, thiab tsis cuam tshuam los ntawm kev hloov pauv ntawm pH nqi.Nws tuaj yeem siv los ntawm 50,000 txog 200,000 viscosities.Lub zog daim ntawv cog lus yog inversely proportional, lub viscosity yog siab, tab sis lub zog yog me me, feem ntau ntawm 50,000 thiab 100,000.Nws yog tsuas yog kom nce qib thiab tsim kho ntawm cov hmoov qhuav mortar, thiab tsim nyog txo tus nqi ntawm cov cement.

Tsis tas li ntawd, cov cement mortar muaj lub sijhawm solidification.Thaum lub sij hawm solidification, phau ntawv tu yuav tsum tau kom nws moist.Vim yog cov dej tuav ntawm cellulose, cov dej noo uas yuav tsum tau muaj rau kev ua kom muaj zog ntawm cov mortar tuaj yeem tau txais los ntawm cov dej tuav ntawm cov cellulose, yog li nws tuaj yeem ruaj khov yam tsis muaj kev saib xyuas tshwj xeeb.

3. Lignin

Lub luag hauj lwm ntawm lignin nyob rau hauv qhuav hmoov mortar yog tiv thaiv cracking.Thaum lignin dispersed nyob rau hauv dej, nws muaj nyob rau hauv daim ntawv ntawm luv fibers.Piv txwv li, thaum tsim cov phab ntsa nrog cov av hauv thaj chaw hauv tsev, cov nplej straw thiab nplej straw yog ntxiv los tiv thaiv kev tawg.Thaum siv lignin, nws yog qhov zoo tshaj los xaiv cov ntaub ntawv ntshiab yam tsis muaj impurities.Thaum txheeb xyuas lignin, koj tuaj yeem tig lub lignin kom pom tias muaj plua plav sab laug.Cov hmoov ntau dua, qhov zoo dua.Los yog muab ib me ntsis lignin rau hauv dej thiab saib, qhov zoo dua qhov dispersion, qhov zoo dua qhov zoo, uas txhais tau hais tias yog nws ntxiv rau qhuav hmoov mortar, nws yooj yim rau disperse thiab yuav tsis tsim ib lub pob.

4. Inorganic bonding khoom

Cov hmoov tshauv calcium hmoov yog calcium hydroxide, feem ntau siv cov khoom siv sib txuas.Nws tsuas yog ua lub luag haujlwm sib txuas hauv cov hmoov putty kom ua tiav cov dej tsis zoo thiab dej-resistant.Muaj ntau ntau limestone tsim nyob rau hauv Suav teb, yog li kev tsim cov txiv qaub calcium hmoov yog feem ntau.Txawm li cas los xij, hauv qee qhov chaw, cov tshuaj khib nyiab ua los ntawm cov kua qaub calcium hmoov uas ua tau tuaj yeem hlawv tawm ntawm daim tawv nqaij ntawm tes thaum tsim kho.Exothermic cov tshuaj tiv thaiv, yog li cov qauv ntawm cov hmoov tshauv calcium hmoov yog alkaline heev.Qhov loj dua cov cua ntsawj ntshab, qhov tsis ruaj tsis khov, thiab nws yooj yim tawg thaum nws khawb ntawm phab ntsa.Peb tab tom nrhiav rau cov khoom siv nrog cov hmoov tshauv ruaj khov calcium hmoov, uas muaj cov qauv me me, zoo whiteness, thiab tsis eroded tes.
