There are many kinds of multi-waterproof coatings on the market, but if they are divided according to the nature, there are only four kinds of waterproof coatings used in the room. They are flexible mortar, hard mortar, one-component polyurethane, acrylic ester, etc. Compare these four waterproof coatings.
1. Flexible mortar: The ratio of emulsion to mortar is 5:4, and it has elasticity. Even if the base layer deforms and cracks, it will not affect the waterproof effect.
Flexible mortar is mostly used on the surface of water, such as wall surface and ground surface. It cannot be used on the back surface of the top surface. If waterproof is not done well, there is water penetration and it is easy to make water seepage.
There is also a kind of silicone-based waterproof coating in flexible mortar, which belongs to high-grade flexible mortar. Its elasticity and flexibility are good, but the price is relatively expensive.
2, rigid mortar: also known as rigid mortar, emulsion and mortar ratio of 1:4, after brushing without coating, can be directly tile, more convenient. After the hard mortar is solidified, the cement hard block is formed and does not cause water seepage. The waterproof effect of the back surface is very good, which is its greatest advantage.
The disadvantage of the hard mortar is that it has a high hardness and is easy to crack with the deformation of the base layer. Therefore, it is generally used for waterproofing the back surface.
3, single-component polyurethane: indoor and outdoor use, brushing is very thick, about 3 mm or so, and the elastic tension of more than 300%, very elastic, any cracking of the substrate will not make it cracking, the best waterproof effect.
Although safety performance control is among the environmental protection requirements, the odor of such a waterproof coating is relatively large, and it is difficult for most people to accept. Polyurethane is colloidal and is very thick. The use of a scraper during construction is laborious and complicated.
After brushing the paint, it is necessary to perform surface treatment, pull the hair or lift sand to increase the friction, and easy to tiling.
4, acrylate: pure liquid, open cover and use. Acrylic is water-based, can be melted in water, it is easy to combine with the ground gap to form a strong waterproof layer, waterproof effect is better than flexible mortar.
After brushing the acrylic, it is necessary to perform surface treatment such as pulling or sand blasting to increase the friction and make it easier to tiling.
The above is the introduction of the four types of indoor waterproof coatings. Each coating has its own advantages. You can choose the most suitable one according to your needs.

Although there are many waterproof coatings on the market and on the network, such as “two-component polymer waterproof coating†and “one-component polyurethane waterproof coatingâ€, etc., the name is professional and there are many types, “one-component†and “two-componentâ€. "The difference is that the mortars are all two-component polymers, ie, they are made from the emulsion and the mortar. The acrylate and the polyurethane are single-component without mortar.

Brass Plated Steel Wire rope is the main substrate for the production of Diamond Wire Saw. Firstly,the artificial diamond particles are consolidated on the metal steel body to make diamond beads,and then the beads are strung on brass plated Steel Wire Rope. The special molds and equipment are used for glue injection molding, and fixing to make a strip-shaped flexible diamond cutting tool. The emergence of Diamond Wire saw mining technology in stone mines is a revolution in stone mining. The technology for stone mining has a wide adaptability, strong function, high efficiency, deep mining depth, and can be cut in various directions such as vertical, horizontal, and inclined planes, high yield, low comprehensive cost, safety and environment protection, and no noise in wire saw mining. No dust and other advantages. In today`s increasingly scarce resources and soaring oil prices, mining granite with wire saws has significant economic and social benefits.
