Yuav ua li cas ua cug lo zoo dua?

Txhim kho cov ntawv nplaum ntawm cug, uas yog qhov tseem ceeb rau muaj zog adhesion thiab ruaj khov, koom nrog ntau cov tswv yim thiab kev txiav txim siab. Ntawm no yog qee cov tswv yim los txhim kho cov kab tshuaj khib nyiab:

1. Cov kev npaj ua haujlwm zoo: xyuas kom meej tias cov nplaim los sib raug zoo yog huv, tsis muaj plua plav, av, thiab lwm yam paug. Rougening lossis ntsuas qhov saum npoo me ntsis tuaj yeem txhim kho cov nplaum los ntawm kev muab cov khoom siv zoo dua.
2. Siv txoj kab cug sib xyaw: Xaiv cov tshuaj khib sib xyaw uas tsim nyog rau cov ntaub ntawv tshwj xeeb thiab cov xwm txheej. Cug tov yuav tsum muaj qhov tseeb piv rau cov khoom xyaw, suav nrog cov xis mas, xuab zeb, thiab dej, kom ua tiav lub zog xav tau thiab ua haujlwm.
3. Ntxiv: COMPORPORITIVATIVATIVATIVATIVEATIVE rau cov tshuaj cug sib xyaw kom txhim kho adhesion thiab nplaum. Cov khoom ntxiv suav nrog:
   • Cov lus qhia txog cov txiv neej zoo lossis polymer polymer: cov tshuaj ntxiv txhim kho txoj hlua khi khoom, hloov tau yooj yim, thiab cov tshuaj khib. Lawv kuj txhim kho kom tiv thaiv dej thiab khov-thaw mus.
   • Cov neeg sawv cev sib koom ua ke: cov neeg sawv cev ua haujlwm xws li Acrylics lossis PVA (polyvinyl acetate) tuaj yeem siv rau lub substrate ua ntej thov kev txaws txhawm rau txhim kho adhesion.
   • Retarders: Cov neeg sawv cev retarding tuaj yeem txuas ntxiv rau kev tshuaj khib kom qeeb lub sijhawm teem caij, tso cai rau lub sijhawm ntau rau kev ua kom zoo dua.
4. Cov dej kom zoo: Ua tiav cov dej kom raug dej-rau-xis mas piv rau hauv cug sib tov. Cov dej ntau dhau tuaj yeem ua rau lub zog cug thiab txo cov tshuaj nplaum, thaum dej me me tuaj yeem ua rau cov pob txhav txhav txhav nrog.
5. Nws cov txheej txheem sib xyaw: ua kom meej kev sib xyaw ntawm cov tshuaj khib cov khoom xyaw kom ua tiav cov tsis sib xws thiab faib cov khoom siv. Siv cov khoom siv neeg kho tshuab rau cov pob loj los ua kom muaj xwm txheej.
6. Cov txheej txheem tsim nyog: siv collhu cap thiab khov kho rau lub substrate siv cov cuab yeej siv trowel lossis cov cuab yeej tsim nyog. Nias lub tshuaj txig khov kho rau hauv qhov chaw, ua kom muaj kev sib cuag zoo nrog rau saum npoo.
7. Ua haujlwm hauv cov ntu tswj hwm: Tsis txhob thov cov tshuaj tua ib zaug, tshwj xeeb tshaj yog nyob rau hauv qhov chaw qhuav lossis qhuav los ua kom qhuav thiab ua tsis zoo. Ua haujlwm hauv cov ntu kev tswj hwm kom muaj kev ua haujlwm kom ua haujlwm thiab ua kom tiav kev sib raug zoo kom zoo.
8. Kev kho mob: Kho kom zoo tshuaj cug yog qhov tseem ceeb rau kev ua kom zoo thiab muaj zog kev txhim kho. Khaws cov tshuaj khib nyiab noo los yog them nrog cov ntawv yas yas rau lub sijhawm kho kom qhuav thiab txhawb kev haus dej ntawm Maas hais.

Los ntawm cov lus qhia thiab cov tswv yim, koj tuaj yeem txhim kho cov nplaum ntawm cug thiab ua kom muaj cov nplaum muaj zog rau koj cov haujlwm tsim kho.
