Glass lined reactor has the mechanical strength of common metal equipment and the stability of glass. It is widely used in chemical production. However, due to the use of force, and in the process of stress corrosion effect and medium, reaction conditions, transport and use is sometimes hot and sometimes cold glass lining material, it is easy to cause enamel surface falling, exploding porcelain and perforation phenomenon, and then influence the normal operation of equipment.
First.How to repair the glass lined reactor
1. to remove the damaged equipment manufacturers, wasting time and labor costs are high.
Such as glass lining reactor repair time is 30 days, 1 5000L reactor repair costs about 20 thousand yuan, 1 sets of 1000L container repair costs about 6 thousand yuan, a tower repair costs about 2 thousand yuan. Thinning and each one plate lining rehabilitation increased strength is also significantly reduced, the complex glass lined reactor can not exceed three times the normal lining normally, such as large or larger equipment such as drop reactor, tower section, storage tank and so on.
Small damage is not necessary to update the equipment, which requires the selection of appropriate repair method to repair, otherwise it will make the reaction kettle by kettle in solvent corrosion, enamel surface damage will expand rapidly, and thus constitute the production, safety accidents and environmental pollution and other unpredictable losses.
2. for glass lined equipment and parts surface lining layer damage repair. This method has the advantages of short repair time and low cost. Such as polymer repair materials (titanium alloy enamel repair agent) repair glass lining equipment corrosion, porcelain, perforation site, one day can be completed, repair costs between 100 to 1000 yuan.
Second. The detailed operation method to repair two, glass lined reactor
1. surface treatment
This is a key step in the successful repair, repair parts was determined after product attachment of the eradication of corrosion sites, with a file, grinding machine or grinder and other things will take off equipment of porcelain or perforated parts clean, leaving medium corrosion of glass lined, iron should not be on the surface of the metal to escape, and the surface roughness, the principle is "the more coarse and better".
With cleaning agent (acetone or alcohol) wipe clean to repair surface. The cleaning area is greater than the surface repair, avoids cleaning the surface pollution again.
3. sizing agent
Domestic series of glass lining repair agent is a pair of clay like agent: A as raw material, B as curing agent. The main ingredients and curing agent are placed in the clean container according to the share of 3:1, and the mixture is fully mixed and dissolved (according to the size of the modified parts to allocate the appropriate amount of glue).
The first few surface repair agent in uniform correction equipment needs repair, glue should try to move in one direction and impose a certain pressure, side edge grinding scraping correction, drive all the air out of the bubble, and to ensure the correction agent and compacting device surface touch.
After the first correction, the remaining correction agent is modified to the equipment correction site to reach the required standard size. After curing the demand of machining, must set aside margin.
Modified parts with iodine tungsten lamp baking equipment, by 6 to 12 hours (depending on the ambient temperature) can be used to bake, listening to the sound check hit the curing effect, repair agent after curing reaction kettle can be used.
