Fly ash are produced principally at coal-fueled electric power plants , which is one of the residues generated in the combustion of coal. Owing to its pozzolanic properties, fly ash is used as a replacement for some of the portland cement content of concrete. It can improve concrete performance, making it stronger, more durable, and more resistant to chemical attack. The reuse of fly ash also creates significant benefits for our environment.

Water based Alkyd resins for industrial coatings

Alkyd resins represent, both historically and commercially, the class of chemical compounds used in the field of paints and stains. Their chemical structure is a continuous and waterproof film which can protect surfaces from multiple strenuous agents conducting an anti-corrosive. The commercial paints based on these resins, the molecules of the structure, in particular, create strong structural interactions involving the formation of films able to cover any type of surface by protecting against aging, weather and wear. the paints made from alkyd resins have been among the first to be used in the construction industry, in particular in the production of exterior paints and enamels, and in the production of products for the treatment of surfaces exposed to particularly arduous conditions, for example various ferrous metal substrates such as structural steel, railings, equipment and machinery.

We offers alkyd resins that have achieved high functionality through modification with other resins such as acrylics, urethanes, epoxies.



Features:



Good storage stability, no ease to hydrolyze;

Environment friendly product, VOC of less than 7%;

Fast dry, and excellent gloss;

unnecessary to add drier during paint preparation;

Excellent shear stability, and can directly use for pigment paste grinding;

Excellent anti-corrosivity, and good initial water resistance;

The finished product paint has good versatility and good in-can appearance, and can replace oil based alkyd anti-rust paint, alkyd ready mixed paint, alkydenamel, etc

Hexagonal Boron Nitride has the same type of layer structure as graphite and provides a very good lubrication/mold-release characteristic. BN is stable up to approximately 2000°C in the inert atmosphere.Besides, Boron Nitride is stable against most organic solvents and corrosive chemicals, and unwettable by most molten metals and glasses. Boron Nitride has high electrical insulation and voltage resistance at high temperature and no changes in permittivity and dielectric loss up to high-frequency area. As for its lubricity and mold-release efficiency, friction coefficient of Boron Nitride does not change up to considerably high temperature in nitrogen atomosphere, which enables use up to approximately 950°C in the air. What's more, because of high thermal conductivity and high heat radiation, BN can be applied to various kind of heat radiators.

Pervaporation membranes can be classified into organic and inorganic membranes. NaA zeolite membrane, as an inorganic membrane, has well-defined zeolitic pores with high hydrophilicity. The pore size of NaA zeolite membrane is 0.42 nm, which is larger than water molecule (~ 2.9 A) and less than most of organic molecular diameters. Therefore, the membrane shows excellent permselectivity and flux for separation of water from organics. Compared to organic membranes, the zeolite membranes have several advantages including higher permeation flux, higher separation factor and better thermal/chemical stability.

During the separation process, the feed solvent is introduced to the feed side of the membrane, and the H2O is removed from the permeate side. The low pressure of the permeate side is maintained by the use of a vacuum pump. Water molecules are preferentially adsorbed on the surface of the membrane, and then permeate through NaA zeolite membrane layer. The driving force of the process is the difference in the partial pressures of water across the membrane. In the feed side, the dehydrated product can be achieved on the retentateï¼?and the H2O in the permeate side is condensed and drained.

Pervaporation process
The pervaporation process is not limited to the gas/liquid equilibrium of the solvent. It can achieve high-purity solvent with low energy consumption, and separate solvents which are difficult to be achieved by traditional separation methods such as distillation, extraction and adsorption. It has obvious advantages for separation of azeotropic or close azeotropic mixtures and dehydration of solvents with minor or trace water, which is a promising technology for substitution of traditional separation technologies. It has a promising application in energy, petrochemical industry, biological medicine, electronics, environmental protection and other fields.

Silicon Nitride (Si3N4) is a man made compound synthesized through several different chemical reaction methods. Parts made of Si3N4 are pressed and sintered by well developed methods to produce a ceramic with a unique set of outstanding properties. Silicon Nitride Ceramic is dark gray to black in color and can be polished to a very smooth reflective surface, giving parts with a striking appearance. The very high quality bodies developed for these demanding high reliability applications are available today and can be used in many severe mechanical, thermal and wear applications.What's more, Silicon Nitride Si3N4 is an electrical insulator and is not wet by nonferrous alloys. Silicon nitride is a rather expensive material, but its performance to cost benefit ratio is excellent in the applications where it can outperform the normally utilized materials with long life and very reliable low maintenance operation.Zirconium oxide (Zirconia) is an extremely tough ceramic with a hardness of >9 Mohs which makes it and excellent material for extreme wear, high temperature and harsh environment applications. Zirconia ceramics have remarkable properties of strength, hardness and wear resistance in addition to withstanding attack from molten metal, organic solvents, acids and alkalis. They can also withstand high temperatures for long periods even under severe mechanical stress. Typical Applications include: volatile chemical solutions transportation, jet and diesel engine components, containers for molten metals, high speed cutting tools, high wear components, transistor insulators, dental implants, bearing balls, pump seals, and ball valves.
