As the saying goes, the foundation is unstable, and strong products will eventually decline. The same is true of epoxy flooring, which has a floor base, which is the same as the foundation for building a house. In order to maintain epoxy flooring for a long time, the key is to deal with the grass-roots. The basic treatment of epoxy floor paint is a must before construction. Floor paint can make the ground smooth and clean, clean and beautiful, but also clean the surface of the oil dirt, to ensure the service life of the floor. If the strength and smoothness of the base can not meet the requirements, the quality of epoxy floor coating or the subsequent use of the floor will bring serious adverse effects. The color of the epoxy floor coating is not uniform in part, and the phenomenon of spot, stripe and color disorder appears. Generally due to improper coating of epoxy floor coatings, as well as some deterioration of the paint caused. (1)原因分析
(1) Cause analysis
Epoxy flooring is due to uneven color dispersion in the paint or inadequate mixing of color paste during color mixing.
Convection occurs in the upper and lower layers of thick coatings, if the density of the two pigments differs greatly.
In the vicinity of the painting site, the gas which can occur with the paint can cause blooming phenomenon.
Reasons and Countermeasures for blooming of epoxy floor construction
The epoxy flooring strengthens the proportioning process, the proportioning is accurate, and the mixing should be even.
Poor solubility or inappropriate viscosity of dilute materials should be adjusted.
Perfect the construction technology of epoxy floor to ensure the thickness of coating film.
Choosing good dispersibility and mutual solubility pigments, choosing the same enterprise, the same batch of products is also a way to avoid blooming.
Sealing curing agent
Four main impacts will be brought to the epoxy floor.
1. Lack of grounding point. According to experts, this is the most worrying thing when making anti-static floor. Because it will seriously affect the discharge of static electricity, and further affect the performance of epoxy anti-static floor. Generally, we should set up a single grounding system for the anti-static floor, which can not be shared with the lightning-proof down-line.
2. Loose grass-roots will lead to a great increase in the cost of floor construction, because a large number of primers are needed to fill.
3. Moisture-proof and water-proof defects, such as delamination and pinholes, are all due to the failure of waterproof and moisture-proof treatment at the grass-roots level, resulting in the moisture content in the soil rising to the surface through the role of capillaries, which will seriously affect the bonding between floor paint and concrete.
4. Low strength. When the bond strength between the base layer and epoxy resin coating is less than 1.5 MPa, it will easily cause ground cracking in the course of use.
