With more and more factories nowadays, the background is getting worse and worse. Many people are thinking about how to take care of the background. The decontamination of the cesspool is one of them. Everyone should be unfamiliar. Let’s look at it. Anti-corrosion coating on its inner wall. With more and more factories nowadays, the background is getting worse and worse. Many people are thinking about how to take care of the background. The decontamination of the cesspool is one of them. Everyone should be unfamiliar. Let’s look at it. Anti-corrosion coating on its inner wall.
The scheme for the construction of the sewage pool with the inner wall of the sewage pool:
1. The effluent tank is covered with deodorizing substrate. It is considered to be suitable and the normal silicate sensible soil of the normal smelting kiln is used. The label is not less than 425 (32.5), and the strength is greater than c25. Soil cement, moisture content is less than 7 percent, pool wall and bottom of the pool are pre-applied with PVC plus layer waterproof treatment. The soil of the sensitive soil is empty, the powder is cracked, the cracks appear and the anti-alkaline soil-sensitive cement surface is smooth and smooth, and the height of the surface is high. The difference is more than 2 m / 2 mm;
2, the sewage tank is covered with deodorizing substrate treatment: check whether there is an empty drum at the bottom of the pool wall. If there is an empty drum, it must be knocked open, and then the epoxy resin natural resin mortar is used to fill the small cracks in the red wall and the bottom of the pool. Potholes and unfairness are filled with epoxy natural resin mortar to fill the flat. For larger cracks, the crack can be cut into V-grooves with a toothless saw, and then filled with epoxy natural resin mortar to fill the flat. The machine grinds the pool wall and the bottom of the pool. Thoroughly finish the floating ash. If the pool is left with oil stains, old paint film, acid and alkali contaminants, it should be cleaned with a special cleaning agent to keep the pool wall clean.
3, the sewage pool is covered with deodorant coating primer: according to the process regulations, a high-permeability epoxy resin natural resin closure primer is applied, and the paint piece is required to penetrate into the pool wall as much as possible, so that the surface of the substrate is absolutely discolored, but not Leave a surfaced paint film as standard 4, paint half-waist paint: use 14-16 mesh / cm 2 of alkali-free degreased glass Cloth suitable for epoxy gas natural resin to perform sewage tank cap deodorization.
The above is about the anti-corrosion coating of the sewage tank with the deodorizing inner wall. It is expected to help everyone's understanding, and it can be absorbed in normal use.

Polishing Wax/polish compound/polish paste belongs to chemical products and commodities, but in fact it is made by physical mixing and heating. Polishing wax also produces grinding, smoothing, smooth, and bright effects through physical movement during use, thereby playing the role of polishing and polishing. Polishing wax has a wide range of uses. It not only refers to the polishing and polishing of metals, but also the polishing of resins PU,PA, plastics, as well as hardwood furniture and appliances.
Polishing is divided into rough polishing, medium polishing, fine polishing and mirror polishing.For metal utensils and utensils of different materials, it is necessary to choose a suitable polishing wax to play a real role and an ideal effect.
