Acid-containing wastewater collection tank
Thread Content
A tank for collecting acidic wastewater needs to be built outside the workshop. The pipes buried underground are made of PPH material. After the tank is poured with concrete, it is intended to cover its entire interior with fiberglass; I’m not sure what the waterproofing properties of this approach will be like. I also wonder how thick the coating should be – are there any good suggestions?
5mm thickness should be sufficient. I’m not sure what the name of your material is, what its pH value is, and what the size of the tank is?
Mix epoxy resin + dibutyl phthalate (plasticizer) + ethylenediamine (curing agent) in a ratio of 100:12-20:8-12. Apply one layer of epoxy resin followed by one layer of glass fiber cloth; use 6 layers of cloth and 8 layers of resin, with a total thickness of around 2 MM. After completion, expose it to direct sunlight for 4-6 hours, or heat it in an oven at 100 degrees for 2-4 hours to cure it.
It is recommended that the poster consult professional anti-corrosion and waterproofing manufacturers, and it is best to have video records of the construction process for inspection by environmental protection authorities
Planning to use epoxy resin with a vinyl lining, 3 layers of fabric and 5 coats of coating, followed by welding a PP sheet on the inside
