The preparations for the installation of glass-lined equipment

1. Use and damage Glass-lined equipment is widely used in the chemical industry. The glass-lined glaze layer attached to the surface of the iron tire is smooth and clean, extremely wear-resistant, and its corrosion resistance to various inorganic organic substances is unmatched by stainless steel and engineering plastics; the glass-lined equipment has the mechanical strength of general metal equipment. It also has the characteristics that general metal equipment does not have: to prevent the material from deteriorating and discoloring, to avoid the metal separation
● Use and damage
Glass-lined equipment is widely used in the chemical industry. The glass-lined glaze layer attached to the surface of the iron tire is smooth and clean, extremely wear-resistant, and its corrosion resistance to various inorganic organic substances is unmatched by stainless steel and engineering plastics; the glass-lined equipment has the mechanical strength of general metal equipment, It also has the characteristics that ordinary metal equipment does not have: preventing material deterioration and discoloration, avoiding metal ion pollution, and low price, convenient and practical. Therefore, glass-lined equipment is the first choice for fine chemical industries such as pharmaceuticals, dyes, and food processing.

Because the glass-lined lining is a brittle material after all, and the harsh working conditions do not allow it to have any tiny cracks, it requires special care during the transportation, installation and use of its equipment, and also pays attention to maintenance. Ensure the safe use of the device.

Even so, damage to glass-lined equipment still exists due to the following reasons:
1. Improper transportation and installation methods;
2. Hard objects such as metal and stones are entrained in the material to impact the wall of the device;
3. The temperature difference between hot and cold shock is too large, exceeding the specified requirements;
4. Strong acid and strong alkali materials corrode under high temperature and high concentration conditions;
5. Overload use under abrasive conditions.

In addition, there are factors such as improper removal of foreign objects and poor quality of the enamel layer. Through the investigation of enterprises using glass-lined vacuum dryer equipment, we learned that if damage was found, it had to be disassembled and transported to its manufacturer to rebuild the enamel layer. This method has serious waste and affects production. Especially in today's equipment prices have increased significantly. Therefore, with the increasingly wide application of glass-lined equipment, it has become necessary to find a simple and fast repairing technology for glass-lined lining, and ceramic metal glass-lined repairing agent (glass-lined reactor repairing agent) came into being as the times require.

2. Titanium alloy repair technology
The repair agent is easy to use, mainly according to the following five steps:
● Surface treatment to remove the deposits on the damaged part, use an angular or straight shank grinder to grind the part to be repaired, the principle is "the rougher the better", and finally clean and degrease with acetone or alcohol (hands, objects are not allowed. touch).
● Ingredients Pour out the base material and curing agent on the work board according to their proportions, and mix them thoroughly to form a dark rubber compound.

3. Paint
● Apply the prepared r-type compound to the surface of the repaired part with a rubber scraper, scrape off the air bubbles, ensure that the surface is in close contact with the repair agent, and cure at 20 - 30 ℃ for 2 hours.
● Brush the prepared s-type material on the surface of the r-type material with a tool. Generally, it is required to paint two layers with an interval of more than 2 hours. Be careful to use it now.
4. Under the condition of 20 ℃-30 ℃, mechanical processing can be carried out in 3 to 5 hours, and it takes more than 24 hours for complete curing. The curing time can be shortened when the coating thickness is high and the temperature is high.

5. The curing effect can be checked by listening to the beating sound. Used tools should be cleaned immediately with detergent.
The use of titanium alloy repair agent on enamel equipment is very effective. Its simple and practical performance not only saves a lot of manpower and material resources for your company, but also brings considerable economic benefits.
