Permanent Ring Magnet With Round Hole 

Product Description:

Bonded NdFeB magnets are manufactured by binding rapid-quenching NdFeB powder. The powder is mixed with resin to form a magnet by compression molding with epoxy or infection molding with nylon. The latter technique is particular effective in large volume production, though the magnetic value of products is lower than those made with compression molding because of their relatively lower density. Various shapes of high dimensional accuracy can be produced without further processing. Surface is treated by epoxy coating or nickel-plating to prevent corrosion.

Construction and Application of Architectural Waterproof Coatings

Different parts of the building waterproofing should choose the appropriate Waterproof Paint For Concrete construction, building waterproofing is based on different parts of the choice of waterproof material is not the same, some parts suitable for waterproofing membrane, some parts suitable for waterproof coating and so on, each part of the Waterproof requirements are not the same. Each waterproof material has its own strengths and weaknesses, a material can not be wrapped around the world, where good materials are not available, all kinds of materials can only complement each other, but can not be replaced, each having its own useless. Roof waterproofing and basement waterproofing, require different material properties, and the bathroom waterproof and wall waterproof more different, sloping roof, complex shape of the roof, the basic metal roofing is not the same, selection should be carefully considered.

1, the Waterproof Roof Coating layer exposed to nature, by the hot sun exposure, the impact of the wind blowing, rain and snow erosion, the temperature of severe cold and summer temperatures, the temperature difference between day and night bloated repeatedly, there is no good material and good protection Measures, it is difficult to achieve the required endurance. Therefore, we should choose high tensile strength, elongation, anti-aging good waterproof material, it is recommended that the roof with high-elasticity acrylic roof Waterproof Paint or polyurea waterproof coating.

2, why the leakage of the wall, because the wall is too thin, mostly for the construction of light brick, a large number of internal and external joints, and then the combination of doors and windows and the wall, tight seal, rain infiltration into the seam. Wall waterproofing can not use the membrane, only waterproof coating, but also with the decoration materials. Window seams only seal sealant to solve the problem, Bridge Waterproof Paint recommended JS polymer cement-based waterproof coating or polyurea clear Waterproof Paint For Basement.

3, underground construction waterproofing materials, underground waterproofing layer soaked in water for many years or very humid soil, waterproof material must be water-resistant, it is recommended Waterproof Paint For Bathroom or cement-based infiltration crystal waterproof coating(waterproof paint for concrete).

4, toilet waterproof three features. First, from the impact of the natural climate, the temperature change is not, the elongation of the material is not demanding; Second, small size, Yin and Yang Kok and more wear floor pipes and more; Third, the wall waterproof paste ceramic tile, and bonding Agent good affinity. According to the above three features, can not use the membrane, only the most suitable waterproof coating, waterproof K11 recommended waterproof paint for bathroom , JS polymer waterproof coating

5, urban construction overpass and other infrastructure projects more and more, reinforced concrete beam must be waterproof, in order to extend the service life. URCKH7 polyurea concrete primer and UMST100 polyurea waterproof coating are recommended for infrastructure engineering. The products are also widely used in pedestrian waterproof paint for bridges, overpasses, viaducts, highway bridges, sea bridges, cross-river bridges, railway subgrade, , Tunnels, reservoirs, dams, fountains, artificial lakes and other areas of water protection.


Do waterproof building, we must choose the right waterproof material, so as to better play the function of waterproof material, will play a very good waterproof effect.
