Yuav Ua Li Cas Mortar Stick Zoo?

Kev txhim kho qhov nplaum ntawm mortar, uas yog ib qho tseem ceeb rau kev ua kom muaj zog thiab kev tsim kho, muaj ntau yam txuj ci thiab kev xav.Nov yog qee cov tswv yim los txhim kho qhov nplaum ntawm mortar:

1. Kev npaj kom zoo: xyuas kom meej tias qhov chaw yuav tsum tau ua kom huv si, tsis muaj plua plav, av, roj, thiab lwm yam kab mob.Roughening los yog qhab nia saum npoo me ntsis kuj tuaj yeem txhim kho adhesion los ntawm kev muab cov khoom siv zoo dua.
2. Siv cov tshuaj khib nyiab kom raug: Xaiv cov tshuaj khib nyiab uas tsim nyog rau cov ntawv thov tshwj xeeb thiab cov xwm txheej.Kev sib xyaw ntawm mortar yuav tsum muaj qhov sib piv ntawm cov khoom xyaw, suav nrog cov cement, xuab zeb, thiab dej, kom ua tiav qhov xav tau lub zog thiab ua haujlwm tau zoo.
3. Additives: Muab cov additives rau hauv cov tshuaj khib nyiab kom txhim kho adhesion thiab nplaum.Common additives muaj xws li:
   • Latex los yog polymer modifiers: Cov tshuaj ntxiv no txhim kho kev sib raug zoo, kev yooj yim, thiab ua haujlwm ntev ntawm cov tshuaj khib.Lawv kuj txhim khu kev tiv thaiv dej thiab khov-thaw cycles.
   • Bonding agents: Bonding agents xws li acrylics los yog PVA (polyvinyl acetate) tuaj yeem siv rau hauv lub substrate ua ntej siv mortar los txhim kho adhesion.
   • Retarders: Retarding cov neeg sawv cev tuaj yeem muab ntxiv rau hauv mortar kom qeeb lub sijhawm teeb tsa, cia sijhawm ntxiv rau kev ua kom zoo dua qub.
4. Cov ntsiab lus dej kom raug: Ua tiav qhov tseeb dej-rau-cement piv rau hauv qhov sib tov mortar.Cov dej ntau dhau tuaj yeem ua rau cov mortar tsis muaj zog thiab txo cov adhesion, thaum cov dej me me tuaj yeem ua rau cov khoom sib tov sib xyaw thiab nyuaj ua haujlwm nrog.
5. Cov txheej txheem sib xyaw: xyuas kom meej sib xyaw ntawm cov khoom xyaw mortar kom ua tiav qhov sib xws thiab kev faib tawm ntawm cov khoom.Siv lub tshuab tov khoom rau cov khoom loj los xyuas kom meej qhov sib xws.
6. Kev siv cov txheej txheem tsim nyog: Siv cov mortar sib npaug thiab khov kho rau lub substrate siv lub trowel lossis cov cuab yeej tsim nyog.Nias lub mortar kom ruaj khov rau hauv qhov chaw, kom ntseeg tau tias muaj kev sib cuag zoo nrog qhov chaw.
7. Ua hauj lwm hauv cov seem tswj tau: Tsis txhob siv mortar rau thaj tsam loj ib zaug, tshwj xeeb tshaj yog nyob rau hauv kub los yog qhuav, vim qhov no tuaj yeem ua rau ziab ntxov ntxov thiab tsis zoo adhesion.Ua haujlwm hauv cov ntu me me, tswj tau kom muaj peev xwm ua haujlwm thiab ua kom muaj kev sib raug zoo.
8. Curing: Kev kho kom zoo ntawm mortar yog qhov tseem ceeb rau kev pom kev zoo thiab kev txhim kho lub zog.Khaws cov tshuaj khib nyiab los yog npog nrog cov ntawv yas rau lub sijhawm kho kom tsim nyog los tiv thaiv kom qhuav sai thiab txhawb dej ntawm cov cement hais.

Los ntawm kev ua raws li cov lus qhia thiab cov tswv yim no, koj tuaj yeem txhim kho qhov nplaum ntawm mortar thiab ua kom muaj zog adhesion rau koj cov haujlwm tsim kho.
