Polyurethane foaming machine equipment spray molding material cold resistance

  

Among all kinds of polyurethane products, the foam plastic of polyurethane high-pressure foaming machine is the most important part. Its main characteristics are that it is porous, so the relative density is small, the specific strength is high, and it also has the characteristics of sound insulation, shock resistance, electrical insulation, heat resistance, cold resistance, solvent resistance and so on. Below small make up to take you to understand the polyurethane foam machine equipment spray molding material cold resistance.

Generally have good mechanical properties, high solid content, all aspects of the performance are better. It is a kind of coating that has development prospect very much at present. The main application direction is wood coatings, automotive repair coatings, anticorrosive coatings, floor coatings, electronic coatings, special coatings and so on. The disadvantage is that the construction process is complex, the construction environment requirements are very high, paint film easy to produce defects.

The single component polyurethane coating mainly includes ammonia ester oil coating, moisture curing polyurethane coating, sealed polyurethane foaming machine coating and other varieties. The application surface is not as wide as the two-component coating, mainly used for floor coating, anticorrosive coating, precoil coating, etc., its overall performance is not as comprehensive as the two-component coating. The varnish variety that get together ammonia fat lacquer calls get together ammonia fat varnish.

Polyurethane foaming machine

  

Polyurethane foams can be divided into soft foams and hard foams. They have different structures and USES. The role of soft foams is buffer, which can be used to make sofas, cushions and other automotive interiors. The application of polyurethane foam plastics is very extensive, in many industries is an indispensable material, and the equipment used to complete the process of polyurethane foam machine is polyurethane high-pressure foam machine, so the use of polyurethane foam importance is self-evident.

The overall layout of the equipment gives full consideration to the use of space. Even if multiple groups of insulation pipes are accommodated, the space designed for mobile passage can still be guaranteed. One operator can push, pull and move the equipment. The realization of the large capacity carrying function of the thermal insulation pipe group of the equipment increases the applicability of the polyurethane foam equipment, greatly facilitates the operator, which not only saves manpower but also improves the efficiency.
