What are the classifications of high-pressure mixing spraying machinery for thermal insulation materials
1. The important role of the on-site polyurethane high-pressure mixed foam external wall insulation system
Polyurethane rigid foam external wall insulation system is a kind of external wall insulation system with good comprehensive performance. It has excellent thermal insulation performance and is suitable for industrial and civil building wall insulation.
At the same time, the on-site spray polyurethane foam is closely integrated with the wall, which can protect the main structure and prolong the life of the building. It has a certain waterproof function and can effectively reduce the occurrence of common problems of external wall leakage.
In addition, because the polyurethane for external wall insulation is a material with high chemical stability, it will not produce harmful gases and is not harmful to the environment.
Therefore, mastering the key points of the construction technology of the on-site spraying polyurethane foam external wall insulation system plays an important role in the promotion and application of building energy-saving technologies and materials.
2. Good heat preservation and flame retardant properties
Strengthen the awareness of flame retardancy and fire protection, focus on the development of new products and technologies such as composite panels and integrated panels, ensure the realization of energy-saving indicators with high-efficiency energy-saving performance, and avoid fire accidents with good fire-resistant performance.
Outer wall rigid foam polyurethane is recognized as the best energy-saving material in the country. As long as it is combined with the improvement of puffing and carbon deposition technology, it should be allowed to play a major role in my country's building energy-saving work.
The application of foreign rigid polyurethane foam in the field of building insulation
Europe: It is currently in a state of coexistence of multiple building insulation systems. Polystyrene is the traditional system in this area, and polyhelium with rigid foam, as a representative of the new system, has begun to be praised by the market, and the upward trend is obvious.
3. Domestic application of polyurethane insulation materials for exterior walls
North America: Mainly supplemented by rigid polyurethane foam system, supplemented by glass wool system, and relatively few polystyrene systems. Since the glass wool system emits toxic gases when exposed to moisture, the Canadian government has promoted the renovation of the original glass wool insulation system into a polyurethane system in recent years.
Four, high-pressure mixed spraying of insulation materials
Using on-site spraying polyurethane foam can achieve seamless construction of exterior wall insulation, so that the interior and the exterior are completely insulated by the overall polyurethane foam, reducing heat loss in terms of material performance and construction technology, and the energy-saving effect is obvious.
At the same time, polyurethane foam has a higher cracking strength. Compared with the polystyrene board thin plaster external wall insulation system, the construction process does not require any cracking mortar and anchors to make the insulation material and the wall tightly integrated. This fully enclosed system greatly reduces the damage to the external wall insulation materials by wind pressure.
Polyurea spraying equipment can be applied to building roofs, tunnels, subways, waterproofing of roadbeds, production of foam membranes and TV props, internal and external corrosion protection of pipelines, auxiliary cofferdam works, corrosion prevention of storage tanks and chemical tanks, pipeline
As we all know, polyurea spraying equipment is an essential tool in life, because of his wide range, multi-purpose, so that we not only in the enterprise even our life also change together. Then want to use good polyurea spraying equipment is not so easy, this time I will bring you after the use of
Polyurethane rigid foam in the state before molding is two kinds of liquid, in the molding of these two kinds of liquid mixing, through the polyurethane spraying machine to become a solid raw material, so the construction molding method is more mobile. As long as it is not crushed polyurethane rigid
Polyurethane foaming process, foam shrinkage, crispy, too soft, heartburn, cracking, smoke and other problems, how to analyze what causes.Polyurethane foaming process by the construction conditions, foaming equipment, construction technology and the impact of environmental temperature, there will be
The common ones are high pressure spraying, polyurethane spraying, hybrid spraying, and polyurea spraying. The construction industry usually uses high pressure sprayers, mostly for industrial production.High-pressure polyurethane spraying machine types:1, from the material of the spraying material i
Polyurethane foaming machine began to appear in foreign countries, with the ease of use and high efficiency by the production industry, and to be widely promoted and used. The polyurethane foaming machine directly determines the quality of the foam produced, even if the quality of the blowing agent
On April 12, CNMC-E3 polyurethane spraying machine was loaded in the industrial park and will be exported to France soon.CNMC-E3 polyurethane spraying machine is widely used in industrial maintenance, tunnel, subway, waterproofing of road base, production of foam film and television props, pipeline
Due to the demand of the production scale, many manufacturers will choose small polyurethane infusion foaming machine to help products for foaming, which can be more convenient for bonding, and in the subsequent use of the process is also more convenient for maintenance. So what are the characterist
Spring Festival does not close, for this year's Spring Festival holiday, CNMC Machinery's Ali International Station store got a good start. We started the year with a salesman, we harvested more than 1.4 million in sales, of which the largest single order reached one million.CNMC Machinery is a subs
Polyurethane sprayers may require special coatings and construction parameters when working with certain specialized types of wood. The following are some common types of specialty woods:
