With the development of industrialization, more and more concrete sealants and solidifiers are used in factories, garages and other places. Concrete sealants and solidifiers are also popular. Now there are many brands and types of solidifiers on the market, and the quality and effect are different. So how to test the good of concrete sealants and solidifiers? Is it bad?
Grounds that have been sealed and cured with concrete and ground that have not been made are usually scratched or markedly improved with keys or steel knives, and curing agents are effective. On the contrary, if there is no significant progress, we must consider whether it is effective.
Two. Test tightness
The sealing property determines whether the concrete inherits alkalization and weathering, dust, anti-fouling and anti-seepage, whether it is easy to clean and so on. After construction, direct dripping on the surface test, the more round the water beads, the more plump, indicating that the better sealing, not easy to bead, easy to disperse, not full, indicating poor sealing.
Three. Test brightness and transparent crystal layer.
In the absence of a brightener, the more crystals the chemical reaction produces, the tighter it is, the more light it reflects, and the brighter it looks with the eye. Good materials can see very thin transparent crystalline layer after construction because of the formation of many crystals, and poor ones are few or no, so brightness and transparent crystalline layer is also one of the indicators of material quality.
Concrete seal hardened floor
At the same time, we can tell you that we can not use the following methods to identify the quality of concrete sealing agents.
1. is there a sense of hand slip?
"Hand slippery feeling", in fact, most of the alkaline solution is through the corrosion of human skin, resulting in a feeling of hand slippery, such as wax, soap water, alkaline concrete sealant curing agent, but the market conditions of acidic concrete sealant materials, there is no such feeling. Hand slip is only a common feature of alkaline solutions, and can not be used to determine the quality of materials.
2. judge whether bubbles are coming.
In fact, there is a certain amount of air in the pores of concrete. It is a dilute solution with fast infiltration. The air in the pores will be replaced quickly, and the air will be discharged quickly, and there will be bubbles. On the contrary, osmotic exudation is slow, and for thick solution, air is slow to discharge, and may be bubbling less or not. So bubbling is only a phenomenon of air discharge, and can not be used to determine the quality of materials.
