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.
Spray gun: Responsible for ejecting the polyurethane coating, typically consisting of a nozzle, nozzle cap, nozzle throat, and trigger.Coating chamber: Provides a sealed environment to maintain the stability of the spraying process, preventing external impurities from entering. It is usually made of
