Speaking of concrete sealants, they are mostly used in cement-based places such as factories, workshops and warehouses. With the continuous expansion of application scope, similar products on the market are also mixed beads in quality. Of course, there are various methods to identify the quality of concrete sealants and curing agents. In fact, in order to ensure the quality of concrete sealant curing agent, the preferred choice is to polish the eyes of consumers to avoid being cheated. Below Luoyang Xin and Yan Li Xiaobian to popularize what we should pay attention to when choosing concrete sealant curing agent and what aspects we should test its quality. 选购误区
Misunderstandings of buying and buying
First, the price of curing agent floor material is determined by unit price of non concrete seal curing agent.
Second. The cost of solidified floor material is not limited to the cost of concrete sealing agent.
Third, not the same concrete seal curing agent products can solve all the problems of the surface of the sealing agent.
Fourth, do not identify the quality of concrete sealant curing agent products through the sensory way such as eyes and hands.
Concrete sealant and curing agent products belong to fine chemical products, through the introduction of the above four points, I hope that you must pay more attention when choosing and purchasing, of course, it can also be through the following points to test its quality first.
1. Judging by whether it is bubbling or not, in fact, there is a certain amount of air in the pore of concrete, which permeates quickly and dilutes the solution. Replacement of pores in the air is fast, the rapid discharge of air, there is bubbling phenomenon. In contrast, the slow, thick solution of permeation slows down the air. There may be little or no bubbling. So bubbling is just a phenomenon of air drained, and we can not judge the quality of material by the second.
2. Judging by whether there is a sense of hand-slip, in fact, most alkaline solutions erode human skin, resulting in a sense of hand-slip, such as waxing water, soap water, alkaline concrete sealant curing agent, but the material of acidic concrete sealant curing agent on the market does not have this feeling. Hand slip is only a common characteristic of alkaline solution, and can not be used to judge the quality of material.
3. The acidic material reacts with the alkaline concrete, so the alkaline material is better than the acidic material. In fact, the materials on the market, whether acidic or alkaline, react with alkaline substances in concrete. Generally, the initial reaction is completed in a very short time and new substances are formed. The alkaline PH value of materials on the market is 10-11, and the acidic PH value is 2-3. All of them belong to strong acidity and strong alkalinity. If they do not react quickly, long-term immersion will corrode the ground, not just simple neutralization reaction. Therefore, it is wrong to say that acidity will neutralize with alkaline concrete, and that alkalinity is better than acidity. Area.
Because the concrete sealant and curing agent floor is a new kind of floor which is widely used at present, it is necessary to polish the eyes in the selection and quality, so as to avoid being blindfolded by some Shanzhai commodities and affect the final use effect.
