What should polyurethane be used for roof waterproof and thermal insulation? In addition to the basic treatment, what are the construction steps for the entire roof waterproof and thermal insulation project? How does Hightop Machinery introduce?
Polyurethane is used for roof waterproof and heat preservation. Make the roof basically flat, without floating dust and oil!
Polyurethane is used to spray rigid polyurethane foam for roof waterproof and thermal insulation. Special equipment sprays rigid polyurethane foam plastic on the base surface to form a dense foam material immediately. According to the thickness of the insulation layer, a construction work surface can be sprayed several times, and the construction work surface of the same day must be sprayed continuously on the same day.
Polyurethane is used for roofing waterproof and thermal insulation to apply surface glue. Apply surface glue on the surface of the polyurethane foam in batches. During construction, make the surface smooth and maintain a constant humidity.
Polyurethane is used for roof waterproofing and insulation and mesh cloth must be added. While the glue is not dry, cover the glass fiber mesh on the surface of the glue, and press the mesh into the glue with a knife.
Polyurethane is used for roof waterproof and thermal insulation to be coated with waterproof and anti-crack glue. After the surface of the previous layer of glue is dry, apply the glue again, the thickness of the two times is not less than 2mm, to ensure the firmness of the exterior layer.
The above briefly describes the relevant steps of polyurethane used in roof waterproof and thermal insulation. For more information on polyurethane, please continue to pay attention to Hightop Machinery.
o provide the security industry with important information such as development scale, speed, industrial concentration, product structure, ownership structure, regional structure, product prices, benefit status, etc., and for the security industry to study and predict the development trend of securit
1. Site selection skills The location of the thermal insulation house of the breeding farm should be a place with a leeward wind and sunny, high terrain and dry soil. 2. Alternative insulation materials for the insulation room of the farmExtruded polystyrene foam (extruded board), molded polystyr
What are the classifications of high-pressure mixing spraying machinery for thermal insulation materials1. The important role of the on-site polyurethane high-pressure mixed foam external wall insulation systemPolyurethane rigid foam external wall insulation system is a kind of external wall insulat
is mostly used in building boards and insulation walls, mainly for heat preservation and waterproofing. The equipment used to complete the polyurethane foaming process is a polyurethane high-pressure foaming machine.The overall layout of the polyurethane foaming machine fully considers the use of sp
For many new products and technologies, only those that have passed theoretical and practical tests are worth recommending. The same is true for polyurethane products. It is recommended that you weigh the relationship between price and value when purchasing polyurethane products. The self-discipline
Polyurea as a new type of environmentally friendly spraying Compared with traditional environmentally friendly coating technology, spraying polyurea elastomer technology has the following advantages:1. It does not contain catalyst, it cures quickly, and can be sprayed on any curved surface, inclined
Polyurethane rigid foam is a material with a large amount of flexible deformation. It has strong resistance to external deformation. It is not prone to cracks under the action of external force, temperature deformation, dry and wet deformation, etc., effectively ensuring the stability and durability
In recent years, China has made innovations in wall insulation materials, especially civil engineering exterior wall insulation systems, exterior wall decoration fire protection systems, etc., and proposed the combination and selection of high-performance insulation materials, but they have achieved
Excellent performance characteristics of polyurethane elastomer: We are a manufacturer mainly engaged in the research, development and production of castable polyurethane elastomer products. Because of the best comprehensive performance, the output of castable polyurethane accounts for more than 60
If it is idle for more than 1 month, the polyurethane foaming opportunity will be blocked and your equipment will be paralyzed. The isocyanate component in the black material system of the polyurethane foaming machine will crystallize if it does not flow for a long time. So what we have to do is to
