How To Repair Fiberglass Tanks?

Although the glass fiber has excellent performance, it is good in terms of hardness and anti-corrosion, but it also causes water leakage in the glass fiber storage tank due to various reasons. After the glass fiber is damaged, it is mostly replaced in the majority of cases, and it is difficult to correct it. It is usually restored by gluing or hot welding. Here Fiberglass Septic Tank Supplier briefly introduces the repair method of gluing.



(1) Clean the glass fiber storage tank. 

First, remove the damaged tank, clean it and dry it, and do the prerequisites for correction.


(2) Cutting.

Cut the appropriately large glass fiber cloth according to the size of the damaged part, remove the wax after baking, and heat it until it does not smoke, and be careful not to fold it.


(3) Glue. 

There are many types of glue solutions, but in general, the two resins, epoxy resin and polyamide resin, are poured into a wide mouth container in a ratio of 1: 1, and they are thoroughly mixed with a stick to stir. It is better to lift the stick without drawing, do not mix too much at one time, so that it can be used up. Second, if the mixture is uneven, the prepared glue will solidify after a while.

This cycle is repeated, just a few layers can be applied, pay attention not to get too thick when coating.


(5) Curing. 

After coating, find a place with a higher temperature to allow it to solidify naturally. Although the moment of demand is longer, it must not be baked with an open flame.

3. In order to ensure the normal operation of the glass fiber storage tank, someone must handle it. It should always check whether the fan and water pump are working properly, whether the spray pipe and air pipe are clear, whether the liquid level in the reservoir is normal, and whether the gas-liquid concentration is within the rules Within the scope, etc., if problems are found, they should be dealt with in a timely manner.

4. Check glass fiber storage tanks on time every year.

5. The user performs concrete foundation construction according to the basic information provided by the manufacturer; this equipment should be installed on the concrete foundation that is more than 100㎜ above the ground.

6, Supporting pipelines, valves, etc. must have a separate support, can not be fixed in glass fiber storage tanks.

7. Pay attention to maintaining the equipment when it is in the equipment, so as not to damage the body and exposed parts. When the tower flange is connected to the external flange, the correct tightening method should be used, and no excessive force should be used to avoid cracking the flange.
