IS THE HIGH-PRESSURE POLYURETHANE FOAMING MACHINE GOOD IN QUALITY?

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

The electric super-capacity sprayer is popular with more and more vegetable farmers because of its convenient use and high work efficiency. It has become the main tool for pest control in the greenhouse. However, electric sprayers are relatively "precious". Once they are improperly operated and main

Reason one why the cold storage uses spray polyurethane to keep cold:　　 Cold storage polyurethane spraying construction plan　　 Cold storage insulation We usually use polyurethane sandwich double-sided color steel cold storage insulation board or spray polyurethane exterior wall directly on the wall

At present, the sprayers sold in the rural market in my country are basically small-sized. Among them, the manual knapsack plastic sprayer (hereinafter referred to as the sprayer) is currently the largest and most common pesticide application device, accounting for 80% of the annual sales of plant p
