1. Catalytic combustion of exhaust gas. This kind of petrochemical waste gas treatment technology has also been catalyzed oxidation technology or contact oxidation technology, which is catalyzed by the catalyst in the lower temperature drop reactor, so that the flammable components in the exhaust gas are treated by oxidative decomposition. The catalysts selected for catalytic combustion can be classified according to their active components, mainly precious metals such as platinum 2 and non-precious metals such as cobalt 3, depending on the different components and properties of the exhaust gas to select different catalysts to achieve catalytic combustion of oxidative decomposition. 2. Irritant and malodorous gas adsorption technology. In general, methods of treating malodorous and irritating gases include combustion, adsorption, and biological deodorization. Adsorption technology utilizes a large surface area of ​​activated carbon and the adsorption capacity of various components in exhaust gas. This technology can be applied to the adsorption of odor and irritant gases with different concentrations, and its relatively strong regeneration capability makes it a relatively broad application. range. Among them, the activated carbon with certain chemical properties can also realize good catalytic activity while its adsorptivity is fully exerted, thereby oxidizing malodor and irritating substances into low-odor and odorless substances. 3. The technology of harmful smoke. Due to the small particle size of harmful smoke, it appears in the air as a tiny wilderness that can be diffused with the movement of air. This type of smog is formed by the condensation of warm gas at a sharp drop in the temperature of the cold air stream. The harmful smoke in petrochemical companies is mainly oil mist and hydrochloric acid mist. In view of the relatively small particle size of harmful smoke, glass fiber filtration method can be used to filter out the harmful smoke.
Aluminium Castings - Sand Castings
Aluminium is a kind of very important material in the casting field, it has the advantage of lighter weight, better elongation, better anti-rust feature, easier for machining, and better surface finish compared with Iron Castings and Steel Castings.
Parts mainly include marine handle parts, turbocharger compressor housing, compressor wheel and so on.
We have the advantages of high and stable quality, strict control on raw material sourcing and inspection, good service and in time feedback for any question from clients, with all these, we have built long-term cooperation with the clients from Europe and USA.
