Common mortar additives muaj xws li thickeners, cement additives, binders, waterproofing agents, expansion agents, etc.
1. Thickener:
Thickener yog ib hom tshuaj mortar additives, uas tuaj yeem txhim kho cov viscosity ntawm mortar, tiv thaiv cov mortar los ntawm kev nkag mus rau cov dej noo ntau dhau mus rau hauv lub hauv paus txheej, thiab ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv phab ntsa. Cov thickeners feem ntau yog hydroxypropyl methyl cellulose (HPMC luv luv), methyl cellulose, thiab lwm yam.
2. Cement additives:
Cement additives yog ib qho khoom siv ntxiv siv rau hauv mortar, uas tuaj yeem txhim kho cov khoom ntawm cov cement, txhim kho nws cov aeration thiab dej txo. Cov cement additives muaj xws li polymer emulsions, cov roj hmab sib xyaw hmoov, polycarboxylate superplasticizers, thiab lwm yam.
3. Cov ntaub ntawv:
Binder yog ib qho ntawm cov tshuaj mortar additives, uas tuaj yeem txhim kho qhov adhesion ntawm mortar thiab txhim khu nws adhesion. Binders feem ntau yog tsim los ntawm ntuj polymers lossis hluavtaws resins. Cov binders muaj xws li polymer emulsion binders, hnyav-raws li binders, thiab lwm yam.
Plaub, tus neeg saib xyuas dej tsis zoo:
Waterproofing tus neeg saib xyuas yog ib tug additive siv nyob rau hauv mortar, uas yuav zoo tiv thaiv ya raws los ntawm nkag mus rau hauv lub hauv paus txheej thiab tiv thaiv phab ntsa los ntawm ntub dej. Tus neeg saib xyuas dej tsis zoo feem ntau yog tsim los ntawm silicone, silicone resin, thiab lwm yam, thiab cov fluorocarbon resin waterproofing tus neeg saib xyuas kuj tuaj yeem xaiv raws li qhov xav tau tiag tiag.
5. Expansion agent:
Tus neeg sawv cev nthuav dav yog ib qho khoom ntxiv uas tuaj yeem ua kom lub ntim ntawm mortar, uas tuaj yeem nce qhov ntim ntawm mortar, txhim kho qhov tawg ntawm phab ntsa, thiab txo qhov hnyav ntawm phab ntsa. Cov neeg sawv cev nthuav dav feem ntau suav nrog cov neeg ua haujlwm nthuav dav, cov tshuaj lom neeg nthuav dav, cov tshuaj slag expansion, thiab lwm yam.
