Ntxuav sab nraub qaum ntawm cov nplais ua ntej. Yog hais tias qhov stains, floating txheej thiab seem seem tso tawm ntawm sab nraum qab ntawm cov vuas tsis huv, nws yog ib qho yooj yim los sau ib zaj yeeb yaj kiab tom qab cov nplaum tom qab cov nplaum tau thov. Nco ntsoov ceeb toom, cov vuas kom huv tuaj yeem pleev xim tsuas yog pleev xim nrog cov nplaum tom qab lawv qhuav.
Thaum ua ntawv thov cov pobzeb sib xyaw ua ke, thov raws li tag nrho thiab nyias li sai tau. Yog tias cov nplaum tau ploj thaum ua cov nplaum, hollowing yuav tshwm sim hauv zos. Lub thicker cov nplaum yog, nws yuav tsum tau siv li thinly li uas ua tau nyob rau hauv tag nrho cov txheej txheej nrawm dua thiab yuav tsis muaj qhov tsis muaj pa ziab.
Tsis txhob ntxiv dej ntxiv rau ib-tiv thaiv nplais nplaum. Ntxiv cov dej yuav dilute cov nplaum thiab txo cov ntsiab lus qub polymer, uas yuav cuam tshuam rau qhov zoo ntawm cov nplaum. Tom qab siv, nws yuav yooj yim coj los teeb meem xws li kev ua polycondens thiab sagging thaum lub sijhawm tsim.
Nws tsis raug tso cai ntxiv cov cement thiab pobzeb nplaum rau ib-tiv nplais nplais nplaum. Nws tsis yog ntxiv. Txawm hais tias cov nplais nplaum thiab xis mas muaj kev sib raug zoo zoo, nws tsis tuaj yeem ntxiv rau cov nplais nplaum. Yog tias koj xav ntxiv dag zog txoj cai xis, koj tuaj yeem txuas cov dej khib nyiab thiab ua tau zoo ntawm cov xis cug.
Ib feem ntawm cov pobzeb nplaum tsis tuaj yeem thov ncaj qha rau ntawm phab ntsa, tab sis tsuas yog rau sab nraum qab ntawm cov vuas. Ib feem ntawm cov nplais nplaum nplaum ua ib qho kev ua yeeb yaj kiab txuas ntxiv ntawm polymers yooj yim, uas tsis tuaj yeem zam thiab txhawb nqa phab ntsa. Yog li ntawd, ib feem ntawm cov nplais nplaum nplaum tsuas yog tsim rau kev ntxiv dag zog rau tom qab cov vuas kom txhim kho cov khoom nplaum ntawm cov pob zeb thiab vuas. Kev ua tau raws li cov nyhuv.
