Phosphating equipment, phosphating production line, phosphating tank, phosphating machinery and equipment factory

Text Phosphating equipment phosphates the workpiece to form a layer of insoluble, non-metallic, non-conductive porous phosphate film on the metal surface. This process changes the workpiece from a good conductor to a poor conductor, thus inhibiting the formation of micro-batteries on the metal surface and doubling the corrosion resistance and anti-rust properties. The porosity of the phosphating film allows the paint to penetrate into these gaps to form Anchoring effect, significantly improves coating adhesion.
Basic process of phosphating equipment
Loading, pre-degreasing, degreasing, water washing, pickling, water washing, neutralization, water washing, surface adjustment and phosphating
One phosphating, two water washing, hot water washing, drying and unloading. The specific process is determined according to the different uses of different workpieces after treatment
The classification of phosphating is classified according to the phosphating film forming system,
There are mainly the following three types of phosphating that are commonly used
Zinc-based phosphor Phosphating is widely used in the adhesion and bonding of primer coatings before spraying
Zinc-calcium phosphating is widely used in coating anti-corrosion and adhesion bonding, anti-corrosion and cold working anti-wear lubrication Manganese-based phosphating is widely used in anti-corrosion and cold working anti-wear Lubrication
According to the phosphating treatment temperature, it can be divided into low-temperature phosphating, medium-temperature phosphating and high-temperature phosphating. Low temperature phosphating is phosphating without heating. Medium temperature phosphating is generally ~
℃
. High temperature phosphating is generally greater than
℃
.
Classification of phosphating equipment. The manual phosphating line determines the size and configuration of the equipment according to the customer's process and production capacity requirements. Guide rails are set up above the tank and a manual electric hoist is installed to control the movement of the workpiece between the tanks. . The temperature and liquid level control of the production line are automatically controlled by the electrical cabinet.
Advantages: Low investment cost
Disadvantages: During the production process, the process time and production rhythm between each tank are difficult to guarantee, and the quality of the phosphated products is not stable enough.
The automatic phosphating line determines the size and configuration of the equipment according to the customer's process and production capacity requirements, sets up guide rails on both sides of the tank, and installs a gantry crane according to the output. The crane is controlled according to the set process sequence and time. The spreaders or rollers in each tank are switched. The temperature and liquid level are automatically controlled. Motors are installed at the sides of each tank and at the loading and unloading positions to control the rotation of the rollers. Advantages: High degree of automation, the production process is completed strictly in accordance with the process sequence and time, fully ensuring the quality of phosphating products. Disadvantages: High equipment investment cost.
