Many people know that the foaming agent cannot be directly made into foam by itself, but can be made into foam through a special foaming machine. These two kinds of mechanical energy play a complementary role and are the most important equipment in the foaming industry. one.
The foaming agent tends to be too hot in the process of work, so to avoid accidents, it is necessary to cool down the foaming machine in time. This kind of heating phenomenon, once the temperature is not cooled in time, will cause the generator to overheat and cause burnout. If it encounters the high temperature in summer, it will greatly increase the incidence of accidents. Therefore, if the foaming machine is working for a long time, it is necessary to do the corresponding cooling work in time, open the door of the foaming machine, do a good job of ventilation, or use electric fans, blowers, etc. to take cooling measures for it. Remove the case to strengthen its heat dissipation capacity.
If the temperature rises too high and the cooling can no longer be done in time, simply stop the work of the foaming machine immediately, and let the machine stop working for about half an hour to restore the normal temperature.
Timing refers to the specified time, and quantitative refers to the number of specifications. The fixed quantitative polyurethane spraying machine sprays the specified amount of polyurethane within the specified time. The program control of the pouring equipment is very accurate, continuous and rapi
With the development of technology and society. Polyurethane spraying machines are also constantly developing and producing higher quality products. From manual foaming to low-pressure spraying machines to the current high-pressure spraying machines, they are also constantly updated and upgraded, co
Polyurea spray equipment is usually used in construction, mainly because polyurea has a strong anti-corrosion effect. Has a certain adhesion and strength. In order to improve the adhesion of the coating, it is necessary to strictly control the substrate used and improve it if necessary, so the polyu
The cold fog machine was once called the normal temperature fog machine, which is relatively speaking with the hot fog machine. It uses high-pressure air generated by an air compressor to form a high-speed rotating airflow through a pneumatic atomizing nozzle. The liquid medicine is formed into tiny
Polyurethane is a heat-insulating and waterproof coating. In buildings, its heat insulation and waterproof functions are widely used. Polyurethane spraying machine is a high-pressure polyurethane spraying equipment, because the material of the high-pressure spraying equipment collides and rotates vi
he polyurea spraying machine includes the main engine, spray gun, feed pump, feed pipe, A component, R component, heating hose and many other parts, which must be connected reasonably to ensure the smooth completion of the spraying operation.The two lifting pumps are respectively inserted into the i
Cold storage insulation we usually use polyurethane sandwich double-sided color steel cold storage insulation board or directly spray polyurethane facade on the wall for insulation. In the southeast of my country, polyurethane sandwich double-sided color steel cold storage insulation boards are most
(1) It does not contain a catalyst, and the curing speed is very fast. It can be sprayed on any kind of curved, inclined and vertical outermost layer without sagging, and it solidifies within 5 seconds. The glue can reach walking strength within 1 minute; (2) It is not very sensitive to humidity a
In recent years, polyurethane resins have made their composites stand out due to their good toughness, fast curing speed, and no styrene smoke. With people's mastery of polyurethane molding technology and progress in controlling its reactivity to extend its service life, polyurethane has long entere
1. What is polyurethane spraying?Polyurethane spraying technology is based on isocyanate and polyether as the main raw materials. Under the action of various additives such as blowing agent, catalyst, flame retardant, etc., through the use of special network equipment and mixing, the high-pressure s
