Practical floor dry goods, epoxy color sand material selection
A table full of delicious food and flavors makes people drool, but this delicious meal can not be done with only one ingredient. This requires the chefs to carefully select multiple ingredients. Made it out. The construction of epoxy colored sand floor is the same as that of gourmet food, and the general materials have been difficult to meet the customer's requirements. We also need to carefully select multiple material combinations to improve the quality of the floor and give customers a perfect answer. But how do we choose materials? This is an issue that we urgently need to resolve.
Don't worry, we have some tips here, please read on.
Selection of colored sand:
Colored sand is also colored quartz sand. A variety of colors give the floor a colorful beauty. When choosing colored quartz sand, its color, roundness, particle size ratio, and chemical resistance must meet certain standards.
Quartz sand should be round or spherical particles. Such quartz sand particles can slide freely during construction, so that the epoxy colored sand layer is fully dense, and the floor is excellent in resistance to heavy pressure and abrasion. It is suitable to use round-shaped granulated colored quartz sand with rounding treatment, and the particle size range is 0.3 ~ 3mm.
Selection of additives:
Colored sand materials have high requirements for coating films, especially under thick film conditions. On the one hand, by adding various additives, the surface tension of the coating film is reduced, which is beneficial to the leveling and defoaming of the coating film; on the other hand, it is necessary to prevent the excessive addition of additives to cause incompatibilities to the resin. , Adhesion between diluent and filler has an adverse effect.
Choice of epoxy resin:
Epoxy resin is required to be able to form a film at normal temperature, and coatings are required to have high adhesion, strong mechanical strength, chemical resistance and good electrical properties.
Secondly, the use of transparent, solvent-free, low-viscosity epoxy resin can fully express the color of the colored sand, increase the texture and aesthetics, and ensure the excellent performance of the floor and environmental protection requirements.
Selection of curing agent:
The selection of curing agent should in principle choose two or more curing agents for compounding to achieve the required mirror effect. Generally speaking, the compounding curing agent should contain anti-water spots and anti-whitening ingredients, while the curing speed is relatively fast and the slower curing agent is compounded to adjust the curing speed.
The combination of the epoxy colored sand materials selected in this way must be a delicious meal, NO, NO, NO (hey, how hungry I am, I still think about food), this is a high-quality Epoxy color sand floor.
