Storage of the polyurethane black and white material spraying machine. The isocyanate and combined polyether barrels should not be exposed to the sun. They must be kept away from heat sources and placed in a cool and dry place. If the barrel is placed upright, no water should accumulate on the lid! It cannot be used up at one time, and the lid must be tightly closed after each use to prevent water vapor and impurities from entering the barrel and affecting the quality. If two or more grades of polyether are used in combination, they should be stacked separately and clearly marked. The combined polyether with common flame retardants should not be stored for too long, and must be used on the day of preparation, otherwise it will easily cause deterioration and affect the foaming quality.
Operation of polyurethane black and white material spraying machine When operating isocyanate and combined polyether, you must wear protective glasses, work clothes and work cap; when operating isocyanate, you should wear clean rubber gloves. The working environment must be well ventilated, clean and hygienic. When the ambient temperature is high, the foaming agent in the combined polyether will partially vaporize and generate pressure. Therefore, the vent cover should be opened to discharge the gas and the pressure should be released before opening the drum cover. When the foam has flame retardant requirements (note: self-extinguishing from the fire), additional flame retardants can be used. The addition amount of ordinary flame retardants is 15-20% of the weight of the white material. The flame retardant must be stirred when added to the white material Foaming can be done after uniformity.
First of all, everyone should know that the small polyurethane high-pressure foaming machine has a wide range of applications in the current society, especially in the construction industry. It has a high application, and it has received the attention of the entire industry. What causes the small polyurethane foam Are machines so popular in the construction industry?
Polyurethane foaming construction method on site: perfusion method: store the two groups of solutions prepared in barrels respectively to filter to the metering pump, which is driven by the air motor, and the material is fed into the barrel to the perfusion mixer, and compressed by one way Air flows into the infusion motor, which drives the stirring shaft to mix the two groups of materials, and then injects them into the mold for foaming.
Spraying method: According to the formula, the two groups of solutions are stored in two barrels respectively. The materials are filtered to the metering pump, which is driven by the air motor, and the material is fed into the barrel to the spray gun body, and the material is brought in by the compressed air regulating valve The mixing chamber, after mixing, is sprayed on the pipe or equipment through the nozzle of the nozzle to foam.
1. Polyurethane material has very good insulation performance characteristics, it is no exaggeration to say that it is the best insulation material in the entire construction industry.
2. Polyurethane foam can form an integral water-repellent layer without seams and has good waterproof performance.
3. Polyurethane materials can be closely adhered to metal tiles, glass and wood, so there is no need to worry about being lifted by the wind.
4. The service life of polyurethane foam can be as high as 30 years, with aging resistance and long service life.
5. Polyurethane materials are simple to construct and indirectly save engineering costs.
