In recent years, extruded boards have been widely used in the manufacturing industry, and their sales volume has gradually increased in recent years. At this time, many illegal enterprises saw business opportunities and chose recycled materials to manufacture extruded boards. Although relevant departments have strictly controlled such items, there are still a large number of recyclable materia...

Extruded boards need to be quantified in engineering use, that is, quantity calculation is required. Usually, what we receive from customers' phone calls are all square quantities, which need to be converted into cubic quantities. Through square quantity × thickness = cubic quantity, because most of the extruded boards in our factory are priced by cubic quantity. Of course, this is not a hard ...

Extruded boards come in many colors, but in fact, the types represented by their colors are all defaulted. Usually gray belongs to the ordinary version, used more for foundation pit backfilling. Blue and green are high-density boards, or flame-retardant boards with flame retardancy. White is mostly floor heating boards. Extruded boards have many uses, and as long as it involves thermal insula...

Geomembrane full reservoir anti-seepage is a commonly used anti-seepage method for reservoirs, and has been widely used in various small and medium-sized reservoirs in engineering. The advantage of using this method is that there is no need to consider factors such as weak links in reservoir terrain, because if the geomembrane construction welding is fine, it can make the entire reservoir not ...

For a long time, fiberglass insulation has been the material of choice for slowing heat transfer through house walls and ceilings. Although it may have the additional benefit of forming a fire barrier between interior and exterior walls, fiberglass may still not be able to achieve the natural capabilities of rock wool boards. Like fiberglass, rock wool is an insulation material, and it is also...

1. Rock wool boards have fire resistance up to 600 degrees Celsius during the production process. Therefore, rock wool insulation materials are formed from actual rock and steel slag, which must be heated to above 600 degrees Celsius insulation to mix the component materials and form this efficient insulation material. With this in mind, mineral wool products can generally resist fire, flames ...

For flower planting, the more important infrastructure is the reservoir, which is an important part of maintaining the entire flower planting system. Therefore, what material to use as the anti-seepage material for the entire water tank is particularly important. Earlier, the material we used was reinforced concrete. From the perspective of cost, it is very high. Usually, a reservoir holding s...
