Installation steps of mechanical seal for pp reactor

Before using the pp reactor, we must close the refrigerant feed valve, then open the mixer, add materials, and then connect the other steam valves and power supply of the pp reactor. Then, let's learn the steps of installing the mechanical seal for the pp reactor!

Electroplating bath: What kinds of plating bath are there in the electroplating process?

Electroplating tank is used to hold solution, for zinc plating, copper plating, nickel plating, gold plating, etc. The mobile cathode electroplating tank is composed of a steel tank lined with soft PVC plastic, a conductive device, a steam heating pipe and a cathode moving device. The tank body can also be steel-lined UPVC. The selection of the tank structure depends on the nature and temperature of the electroplating bath solution. So electroplating bath: what kinds of plating bath are there in the electroplating process?

Electroplating bath: What is the reason for the blackening of the electroplating gold layer?

The materials used for manufacturing electroplating bath lining are determined by the nature of the electrolyte (corrosion resistance, temperature resistance, etc.). Commonly used are PVC, polypropylene hard (soft) sheet, titanium plate, lead plate, ceramic, etc. What is the reason for the blackening of the electroplating gold layer?

Precautions during cooling PP reactor

The standard configuration of the cooling PP reactor is 10MPA, that is, 100 atmospheric pressure. The cooling PP reactor of 20MPA or 30MPA can be customized. As for the pressure of the reactor, it should be selected according to the experimental conditions. The bigger the worse. Each cooling PP reactor has a safety valve and alarm control system, so safety can not be considered. On the other hand, the greater the external pressure is, the thicker the kettle wall is, the heavier the pressure is, the larger the corresponding pressure measuring range is, and the more inaccurate the manometer's marketability is. If the pressure is large, and it needs to be read accurately, it is recommended to buy a digital manometer. However, the digital manometer has a large dial and an unattractive appearance, and the cost is higher than the pointer manometer. Then, let's understand the matters needing attention in the process of cooling the PP reactor together!

The customized manufacturer of spray tower introduces the precautions for use of spray tower

PP spray tower is a simple equipment for gas absorption. In the spray tower, the liquid is the dispersed phase, the gas is the continuous phase, and the gas-liquid ratio is generally small, which is suitable for the absorption process with very fast or very fast chemical reaction.

The electroplating tank manufacturer will tell you the working principle and characteristics of the spray tower

When the dusty waste gas or oily waste gas passes through the spray tower, liquid medium, some alkali liquor and some sulfuric acid solution will be ejected from the proper position in the tower (depending on the scheme). If the waste gas contains acid, alkaline solution will be selected to neutralize the acid; If the waste gas contains alkalinity, choose sulfuric acid solution for absorption. The specific selection of acid-base solution depends on the nature of the waste gas and the situation of the enterprise itself.

Cleaning method of PP reactor

Garbage is easy to remain in the reactor that has been used for a long time. It gradually accumulates in the reactor over time, which not only affects the capacity of the reactor, but also affects the reaction. In addition to correct operation and routine maintenance, PP reactor also needs to pay attention to cleaning requirements. For example, after each operation, it is necessary to remove the residue on the kettle body and sealing surface with cleaning solution (pay attention to using cleaning solution to prevent the main material from corrosion). It is necessary to clean it frequently. It is not allowed to clean it with hard substances or things with rough surface. Now let's learn about the cleaning method of PP reactor!
