Cov Plasters & Renders Zoo Tshaj Plaws: Yuav Ua Li Cas RDP thiab Cellulose Ethers Txhim Kho Kev Ua Haujlwm

Hauv kev tsim kho niaj hnub no, Hmoov Polymer uas yaj tau dua (RDP) ua ke nrog cov cellulose ethers muab kev txhim kho uas hloov pauv qhov kev ua si hauv plaster thiab render mortars. Cov tshuaj ntxiv no daws cov teeb meem uas tshwm sim ntau - kev nplaum tsis zoo, tawg, dej nkag, thiab kev siv tsis sib xws - ua rau lawv tseem ceeb rau cov neeg cog lus, cov neeg ua haujlwm tshwj xeeb, thiab cov chaw tsim khoom.

1. Vim li cas thiaj siv RDP hauv Plasters & Renders?

• Kev Sib Txuas Zoo Dua & Kev Sib Koom TesRDP tsim ib zaj duab xis polymer uas yooj ywm thaum rov tawg, txhim kho kev sib txuas ntawm cov khoom siv thiab tshuaj lom neeg rau cov khoom siv xws li pob zeb thiab cib.

• Kev Ywj Pheej Zoo Dua & Kev Tiv Thaiv Kev TawgLub network polymer nqus cov kev txav ntawm cov qauv thiab kev hloov pauv ntawm qhov kub thiab txias, txo qhov micro-cracking.
• Kev Tiv Thaiv Dej Zoo Tshaj PlawsZaj duab xis RDP tiv taus cov dej noo nkag, txhim kho kev tiv thaiv dej rau sab nraud thiab thaj chaw noo noo.

2. Kev Sib Koom Tes nrog Cellulose Ethers

• Kev Tswj Xyuas Rheology & Kev Khaws DejCov cellulose ethers (piv txwv li HPMC, MHEC) tswj qhov viscosity, tiv thaiv kev sagging, thiab tswj cov dej noo tas li thaum lub sijhawm kho - tseem ceeb rau kev tsim cov zaj duab xis polymer zoo tshaj plaws.

• Daim Ntawv Thov du thiab tiav: Tswj kev sib koom ua ke ntawm cov mortar, lawv txhawb nqa qhov chaw du thiab sib xws - zoo tagnrho rau kev ua tiav zoo

3. Cov txiaj ntsig tseem ceeb hauv kev siv tiag tiag

Kev nplaum thiab kev ruaj khov

Cov plasters thiab renders nrog RDP qhia tau tias muaj zog substrate adhesion, txawm tias ntawm cov nto du lossis qis-absorption, txo cov delamination thiab txhim kho lub neej ntev.

Kev Tiv Thaiv Kev Tawg

Cov zaj duab xis RDP elastic thiab kev khaws cia dej zoo tshaj plaws tiv thaiv kev tawg ntawm kev ntxhov siab dhau sijhawm, tswj kev ruaj khov ntawm cov qauv

Kev Tiv Thaiv Dej & Kev Tiv Thaiv Huab Cua

Cov mortars no tiv taus dej nkag mus, txo cov teeb meem ntub xws li efflorescence lossis pwm hauv cov ntawv thov sab nraud .

Kev Ua Haujlwm Tau & Kev Zoo Tag Nrho

Cov khoom sib xyaw zoo sib npaug muab kev du, zoo rau trowel thiab lub sijhawm qhib ntev, txo kev siv zog ua haujlwm thiab ua kom tiav qhov zoo tshaj plaws

Xaus lus

Los ntawm kev sib koom ua ke RDP thiab cellulose ethers, plaster thiab render mortars ua tiav:

• Ruaj khov kev sib txuas rau ntau qhov chaw sib txawv

• Kev tiv thaiv tawg los ntawm cov tes hauj lwm polymer uas yooj ywm

• Zoo dua kev tiv thaiv dej thiab kev ruaj khov ntawm huab cua

• Txhim kho kev ua haujlwm tau thiab qhov zoo ntawm qhov chaw
