RDP rau kho mortar

Redispersible Polymer Powder (RDP) feem ntau yog siv los kho cov tshuaj mortar los txhim kho ntau yam khoom thiab txhim kho kev ua haujlwm ntawm cov khoom kho. Nov yog cov kev siv tseem ceeb thiab cov txiaj ntsig ntawm kev siv RDP hauv kev kho mortar:

1. Txhim kho Adhesion:

• RDP txhim kho qhov adhesion ntawm kev kho mortar rau cov substrates sib txawv, suav nrog pob zeb, masonry, thiab lwm qhov chaw. Qhov no txhim kho adhesion ua kom muaj kev sib raug zoo ntawm cov khoom kho thiab cov qauv uas twb muaj lawm.

2. Flexibility thiab Crack Resistance:

• Qhov sib ntxiv ntawm RDP imparts yooj rau kho mortar, txo qhov kev pheej hmoo ntawm kev tawg. Qhov no yog qhov tseem ceeb hauv kev kho cov ntawv thov uas lub substrate yuav muaj kev txav los yog thermal expansion thiab contraction.

3. Ua haujlwm tau zoo:

• RDP ua haujlwm raws li kev hloov kho rheology, txhim kho kev ua haujlwm thiab yooj yim ntawm daim ntawv thov kho mortar. Qhov no tso cai rau kom zoo dua shaping, smoothing, thiab tiav thaum lub sij hawm kho.

4. Kev tuav dej:

• RDP pab txhawb dej tuav hauv cov tshuaj khib nyiab kho, tiv thaiv dej sai sai thaum lub sijhawm kho. Kev ncua sij hawm ua haujlwm tau zoo tshwj xeeb rau kev ua tiav qhov du thiab zoo ib yam.

5. Txo Sagging:

• Kev siv RDP pab txo qis sagging los yog slumping ntawm kho mortar, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov ntsug. Qhov no ua kom ntseeg tau tias cov khoom siv kho kom zoo rau qhov chaw ntsug yam tsis muaj deformation.

6. Teem sij hawm tswj:

• RDP tuaj yeem siv los tswj lub sijhawm teeb tsa ntawm kev kho cov mortar, tso cai rau kev hloov kho raws li qhov project tshwj xeeb. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev kho cov ntawv thov nrog qhov sib txawv ntawm qhov kub thiab txias.

7. Txhim kho Durability:

• Kev koom ua ke RDP rau hauv kev kho cov tshuaj mortar txhim kho tag nrho cov kav ntev thiab huab cua tsis kam ntawm qhov chaw kho. Qhov no yog qhov tseem ceeb rau kev ua kom lub neej ntev ntawm kev kho hauv ntau yam ib puag ncig.

8. Compatibility nrog lwm yam additives:

• RDP feem ntau sib xws nrog lwm cov tshuaj ntxiv uas feem ntau siv los kho cov tshuaj khib nyiab, xws li plasticizers, accelerators, thiab fibers. Qhov no tso cai rau kev kho cov khoom kho raws li cov kev xav tau tshwj xeeb.

9. Txhim kho Bond Strength:

• RDP pab txhawb kev txhim kho kev sib raug zoo ntawm cov mortar kho thiab cov substrate, muab kev kho kom ruaj khov thiab ruaj khov.

Kev xaiv cov qib uas tsim nyog thiab cov yam ntxwv ntawm RDP yog qhov tseem ceeb rau kev ua tiav qhov kev xav tau hauv kev kho cov khoom siv mortar. Cov neeg tsim khoom yuav tsum ua raws li cov lus qhia pom zoo thiab cov lus qhia ntau npaum li cas los ntawm RDP cov neeg muab khoom thiab xav txog cov kev xav tau tshwj xeeb ntawm lawv cov qauv kho. Tsis tas li ntawd, kev ua raws li cov qauv kev lag luam thiab cov kev cai yog qhov tseem ceeb los xyuas kom meej qhov zoo thiab kev nyab xeeb ntawm cov khoom kho mortar.
