PP material advantages and disadvantages of sewage treatment equipment, first of all, we have to understand what is PP material, PP material full name is polypropylene, is a kind of white appearance of the wax material, transparent and very light. This material can resist acid, alkali, salt liquid and a variety of organic solvents corrosion, so many medical, chemical, food and other industries like PP material, we usually use some of the mineral water bottles are also the use of PP material.
Resistant to corrosion, light weight, good toughness, these characteristics are very suitable for sewage treatment equipment, and we also know that the traditional carbon steel, fiberglass tanks will be involved in welding, environmental protection and other issues. But PP winding tank production is simple, the barrel part of the one-time processing molding, thickness and size can also be manually adjusted, and PP material tank can be recycled and reprocessed, more environmentally friendly.
We often find that PP tanks are beige, gray, like our Liding production of PP tanks are also beige mostly, this is because the manufacturers of raw materials inside the addition of dyed particles, not because of the color change caused by heating, this color on the one hand, is resistant to dirt, on the other hand, the current market to buy sewage treatment equipment for the crowd is also more recognized this color, is considered a market guide.
While this PP material sewage treatment equipment has corrosion resistance, light weight, strong load these advantages, but need to pay attention to the PP material at low temperatures will deteriorate impact resistance, weather resistance is also poor, so the general PP material sewage treatment equipment needs to be buried. If there is such an above-ground sewage treatment equipment like Liding Scavenger, we must ask the manufacturer how the weather resistance, and inform the use of environmental conditions, with or without modification or protective measures, etc., to prevent the service life is too short, reducing the cost-effectiveness of the equipment.
