Lub luag hauj lwm dab tsi-refispersible polymer hmoov ua si hauv cug cug?

Recispersible polymer hmoov (RPP) ua si ntau lub luag haujlwm tseem ceeb hauv kev sib nraus, tshwj xeeb hauv kev txawj ntse thiab polymer-hloov kho. Ntawm no yog cov luag haujlwm tseem ceeb uas cov neeg rov ua haujlwm polymer hmoov ua haujlwm hauv tshuaj khib nyiab:

1. Txhim kho Adhesion: RPP txhim kho cov nplaum ntawm ntau yam substrates rau ntau yam nkaus, suav nrog cov pob zeb ua, ntoo, thiab cov hlau ntoo. Cov nplaum no pab tiv thaiv kom xeb thiab ua kom muaj kev sib raug zoo ntawm cov tshuaj khib thiab txheej.
2. Txhim Kho Yooj Yim: RPP imparts yooj kob cug, ua rau nws tiv thaiv ntau dua thiab deformation. Qhov no yog qhov tshwj xeeb tshaj nyob rau hauv cov ntawv thov uas cov txheej txheem yuav muaj kev txav los yog thermal expansion thiab cua.
3. Ua kom muaj dej ua kom nce ntxiv: RPP txhim kho cov khoom siv tshuaj khib nyiab, tso cai rau kev ua haujlwm ntev ntawm cov khoom siv xis. Qhov no ua rau muaj kev ua haujlwm zoo, txuas ntxiv qhib lub sijhawm, thiab txhim kho adhesion, tshwj xeeb tshaj yog nyob rau hauv cov mob kub lossis cua hlob.
4. Kev Txhim Kho Cov Haujlwm: RPP txhim kho cov haujlwm ua haujlwm thiab sib xyaw ntawm cug, ua rau nws sib xyaw, thov, thiab kis. Qhov no tso cai rau kev pab them nqi zoo dua thiab ntau yam kev muab tso cai, txo qhov ua kom zoo li ntawm voids lossis qhov khoob hauv cov kab clu siav.
5. Txo cov shrinkage thiab tawg: los ntawm kev txhim kho adhesion, hloov chaw, thiab dej pab txo cov shrinkage thiab tawg ua kab vaph. Qhov no yog tau txais txiaj ntsig tshwj xeeb hauv cov ntawv thov uas shrinkage cracks tuaj yeem ua rau muaj kev ncaj ncees thiab cov tshuaj khib.
6. Ua kom muaj zog dua thiab ua kom muaj zog: kev siv RPP tuaj yeem txhim kho cov tshuab cug, suav nrog compressive lub zog, lub zog compression, flexural zog. Qhov no ua rau muaj cov tshuaj khib nyiab ntev dua thiab ntev ntev, haum rau ntau yam ntawm kev siv kev thov.
7. Modutify Rheology: RPP tuaj yeem hloov kho cov tshuaj khib nyiab ntawm cug, xws li viscosity, thixotropy, thiab sag tsis kam. Qhov no tso cai rau kev tswj tau zoo dua rau daim ntawv thov thiab kev tso cov tshuaj khib, tshwj xeeb tshaj yog nyob ntawm ntsug lossis ua haujlwm tshaj plaws.
8. Muab cov khov-thaw kuj: qee hom RPPs yog tsim los txhim kho ntawm cug tshuaj khib, ua kom haum rau kev siv nyob rau hauv cov huab cua txias lossis ib puag ncig uas khov-thaws kycles tshwm sim.

Redispersible polymer hmoov ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov kev ua yeeb yam, ua rau cov vuas pov tseg, kho kom zoo thiab kho kom zoo dua qub, thiab waterproofing.
