   Redispersible latex powder products are water-soluble redispersible powders, which are divided into ethylene/vinyl acetate copolymers,  vinyl acetate/tertiary ethylene carbonate copolymers , acrylic copolymers, etc. agent, with polyvinyl alcohol as protective colloid. This powder can be quickly redispersed into an emulsion after contacting with water. Due to the high binding ability and unique properties of redispersible polymer powders, such as: water resistance, construction and heat insulation, etc., their The range of applications is extremely broad. It has outstanding bonding strength, improves the flexibility of the mortar and has a longer opening time, endows the mortar with excellent alkali resistance, and improves the adhesiveness, flexural strength, water resistance, plasticity and wear resistance of the mortar. In addition to the construction property, it has stronger flexibility in the flexible anti-crack mortar. Dry-mix formulations are essential for transporting and ke

Xenon is a rare , odorless, colourless, tasteless, chemically unreactive gas. It was regarded as completely inert until, in 1962, Neil Bartlett reported synthesis of xenon haxafluoroplatinate. In a gas filled tube xenon emits blue light when excited by electrical discharge. Applications Xenon has relatively little commercial use. It is used in photographic flash lamps, stroboscopic lamps, high-intensitive arc-lamps for motion picture projection and high-pressure arc lamps to product ultraviolet light (solar simulators). Other uses are as general anaesthetic, xenon 'blue' headlights and fog lights are used on some vehicles and are said to be less tiring on the eyes. They illuminate road signs and markings better than conventional lights. Xenon in the environment Xenon is a trace gas in the Earth's atmosphere, occurring in 1 part in 20 million. The only commercial source of xenon is from industrial liquid-air plants. World production is less than 1 tonne per year, although re

  Spherical Lenses   Spherical lenses  - also sometimes referred to as singlets - are optical lenses that feature a spherical surface with a radius of curvature that is consistent across the entire lens. They are constructed such that the light entering them diverges or converges, depending on the lens design. Concave spherical lenses have a negative focal length that causes incident light to diverge (creating a virtual image). In contrast, convex spherical lenses have a positive focal length that causes incident light to converge (creating real and virtual images). The real images formed are highly focused, while the virtual images formed are highly magnified. The main advantages of using spherical lenses in optical systems are their simpler surface design and lower manufacturing cost. These benefits make them suitable for various imaging applications in a diverse set of markets. Plano-convex lenses are often used in light collimation and monochromatic illumination operations that req

  In common with most commercial nitrogen fertilizers, urea is manufactured from anhydrous ammonia (NH3). The high analysis of urea — 46% N — is the main reason for the low cost of this form of nitrogen fertilizer. Freight costs and storage and handling are all lower than with lower analysis fertilizers such as ammonium nitrate (34-0-0) or ammonium sulfate (21-0-0). Urea 46% Nitrogen a white crystalline solid containing 46% nitrogen, is widely used in the agricultural industry as an animal feed additive and fertilizer.  Fertilizer urea   can be purchased as prills or as a granulated material. In the past, it was usually produced by dropping liquid urea from a  “ prilling tower ”  while drying the product. The prilled formed a smaller and softer substance than other materials commonly used in fertilizer blends. Today, though, considerable urea is manufactured as granules. Granules are larger, harder, and more resistant to moisture. As a result, granulated urea has become a more suitable
