Purchase of enamel chemical equipment

purchase of chemical enamel equipment

1. Before purchasing enamel equipment, you should understand in detail the technology, production, reputation and other conditions of the pre purchased enamel manufacturer, and try not to purchase the enamel equipment of the manufacturer whose products often have problems due to price reasons

2. Explain the actual medium environment of the enamel reactor to the enamel manufacturer, and simulate the production environment for the thrust calculation and corrosion test of the electromagnetic vibration resistance testing machine of the enamel if possible

3. Due to the particularity of the fixture structure of the experimental machine, it is sometimes difficult for us to determine which kind of fixture is more suitable for comparing the performance of the sample with the actual production environment

4. The enamel equipment to be purchased should stand for more than half a month (the longer the better) after being assembled to eliminate the residual stress

II. Precautions for use and operation

(1) feeding:

be careful when feeding. There should be no hard objects falling into the enamel container. At the same time, the heating material of empty tank and the cooling material of hot tank should be avoided as far as possible. The temperature difference should not exceed the technical index of the equipment. Block metal or sundries shall be strictly prevented from being carried in the material adding equipment. For large hard materials, they shall be added after crushing. Try to reduce the temperature difference between the materials and the tank wall, and avoid heating materials in the cold tank or adding cold materials in the hot tank; Nowadays, more and more plastic processing enterprises are buying the so-called "universal" experimental machine

(2) Operation:

when using jacketed equipment, slowly pressurize and heat up. The pressure of 0.1mp should be applied in advance and maintained for a quarter of an hour, and then the steam should be slowly applied to reach the operating pressure. If conditions permit, the appropriate temperature rise and fall curve can be found according to the actual situation of the unit, which is generally controlled below 3 ℃/min. During the operation of the equipment, pay attention to the sealing of flanges, adapter plates, Manholes with welded or cast flanges and stuffing boxes, and take immediate measures in case of leakage

(3) discharging:

in case of blockage at the bottom of the tank during discharging, do not shovel with metal tools, but gently poke with a bamboo rod, plastic rod or wooden rod. When cooling is required after the reaction, cooling water must be supplied to the jacket after the temperature in the tank naturally drops to a certain extent to prevent sudden cooling. In the alternating action of acid and alkali, the service life of non alkali resistant enamel equipment is greatly shortened, so attention should be paid to the selection of enamel equipment with good alkali resistance. Acid resistant enamel should not be used in acid-base alternating occasions. When discharging, if enamel debris is found, open the can immediately for inspection, and then use it after repairing the porcelain surface
