The high-pressure foaming machine is a kind of equipment in which polyether polyols and polyisocyanates are foamed by chemical reaction in the presence of a variety of chemical hoeing agents such as foaming agents, catalysts, emulsifiers and so on. The high-pressure foaming machine is not equipped to produce uniform and qualified foam products, so it is very popular in the market.
Pay attention to cleaning the polyurethane high-pressure foaming machine in normal use. One of the important steps in the cleaning of the heating pipe of the polyurethane high-pressure foaming machine. When spraying is finished, press the pressure relief button and then fire the gun to relieve the pressure to about 50-70psi. At this time, the pressure relief button indicator will go out. You can also see if the piston rod of the proportional cylinder has been retracted into the cylinder. If it has retracted, the pressure relief can be stopped.
Because when there is a certain pressure in the pipe, the moisture in the air will not easily enter the pipe, ensuring that the raw material is not affected by the humid air, and the A material will not deteriorate and crystallize in the pipe. This method is very harmful to the maintenance of the equipment during the daily use. helpful.

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
