Among various polyurethane products, polyurethane high-pressure foam is an important component. The main feature of the high-pressure foaming machine is its porosity, so the relative density is low, the strength is high, and it has the characteristics of sound insulation, vibration resistance, electrical insulation, heat resistance, cold resistance, and solvent resistance. Next, the editor will introduce you to the relevant content of the polyurethane foaming machine.
Polyurethane foaming machine has good mechanical properties, high solid content and various properties. At present, it is a promising paint variety, which can be used in wood coatings, automotive repair coatings, anti-corrosion coatings, floor coatings, electronic coatings, special coatings, etc. However, the disadvantage of this coating is that the construction process is troublesome, and it has high requirements for the construction environment.
Polyurethane coatings, moisture-curing polyurethane coatings, closed polyurethane foaming machine coatings and other varieties belong to single-component polyurethane coatings, which have a wider range of applications than two-component coatings. Floor coatings, anti-corrosion coatings, pre-formed coatings, etc. are all single-component polyurethane coatings used, but their overall performance is not as comprehensive as two-component coatings.
The foam produced by the polyurethane foaming machine has soft foam and hard foam. Because the two materials have different structures, they also have different uses. For example, soft foam is suitable for soft materials such as car cushions and sofas at home; while rigid foam
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 space. Even if it accommodates multiple insulation pipe groups, its design can ensure the passage of space, and one operator can push and pull the mobile equipment.
The main function of polyurethane foaming machine equipment for refrigeration equipment is to play a role in heat preservation, but the quality of heat preservation performance cannot be observed with the naked eye before actual use, so the material selection needs to be strictly controlled.
Polyurethane foaming machine equipment uses structural amine ether to reduce thermal conductivity and improve thermal insulation effect. Try to reduce the water content in various raw materials and formulations to avoid the main polyether from causing the thermal insulation performance to decline due to water foaming: Select products in large factories. Compared with polyether processed in small and medium-sized factories, the foam produced by large-scale factories has high density, thin pore walls, and good thermal insulation characteristics, which can effectively adjust foaming-condensation. The balance of the glue reaction.
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
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
