Shandong Shengya Machinery Co., Ltd. specializing in the production of various types of brick, brick machine, brick machine, hollow brick, pavement brick and other equipment of the old brick factory.
   Most are in the weldment cement brick, flat, cylinder components. True to the different uses of cement brick embalmed, here are some some experience in anti-corrosion materials and manufacturing methods.
      1. Hydraulic cement brick phosphate - Passivation Process
Vibration fluidized bed in the manufacture of cement brick, seventy percent of the parts are steel structures. A longer turnaround time between process and therefore generate a large amount of surface rust before painting required much manual to rust. Phosphating - passivation process, through electrical and electrochemical reactions, by a one-time treatment, can make and full of rust steel workpiece surface showing the original color of the metal, while generating a dense layer on the metal surface rust . It can place ten days in the humid air, and will not rust. Its method of operation is simple and can improve the working environment, reduce labor intensity, save manpower and resources. Of phosphate - passivation solution containing emulsifiers, molybdates, and a variety of acid soluble phosphate, which is not only used in the above models, or other similar structure frame can be preserved using this method deal with.
      2. Discussion of hydraulic cement brick austenitic nickel-chromium stainless steel welding
Cement brick, there are many plate welded structure, most of the sheet metal is 1Cr18Ni9Ti (18-8 type). Corrosion, fracture and other problems often occur during welding. Seriously affect product life and performance. The difference between ordinary carbon steel and austenitic stainless steel is poor thermal conductivity, thermal expansion coefficient when the resistance value is high. Because of these properties of austenitic steels, require special welding processes to weld.
Hydraulic cement brick is one of the main problems of high-alloy steel. This high corrosion resistance of steel itself, but the welding process reduces the corrosion resistance. Austenitic steel welding corrosion forms: whole, local, intergranular corrosion. The introduction of foreign domestic cement brick factory, bag filter of stainless steel frame due to improper welding destroy the organizational structure of the material cause intergranular corrosion, the drying process material containing acidic components, steel soon cause rupture.
      3. The hydraulic cement brick electrostatic powder coating on the cement brick manufacturing applications YXQ4-40 new fixed small hollow brick.
Traditional paint is a liquid, which contains large amounts of ketones and esters hydrocarbons and other organic solvents, to the production, transportation, construction has brought a series of troubles, flammable and very safe. Because there is a certain degree of toxicity, volatilization into the atmosphere, seriously polluting the environment. Therefore, the paint experts at home and abroad are less committed to the development of new coating solution or not a solution. One such novel coating is a powder coating.
Vibration fluidized bed cement brick-on cover, mostly cold-rolled stainless steel sheet, and therefore costly. Why use stainless steel rather than ordinary steel, because a hydraulic pad machine in working condition will be exposed to a variety of corrosive materials and gases, and corrosion resistance of stainless steel can be very advantageous, therefore made of stainless cold-rolled sheet steel.
Electrostatic spraying polyester resin powder coating ordinary carbon steel, the corrosion resistance of stainless steel completely comparable. Since the powder coatings have a tough, durable, decorative and good, and has excellent outdoor weathering resistance and heat resistance, but also has excellent corrosion resistance and resistance to chalking performance, superior gloss and color light performance, so, electrostatic Powder coating is fully applicable to antiseptic hand dryers brick housing.
