Among all kinds of polyurethane products, polyurethane high-pressure foaming machine foam is an important part. The main feature of polyurethane coating is that it has porosity, so the relative density is small, the specific strength is high, and it also has sound insulation, shock resistance, electrical insulation, heat resistance. , cold resistance, solvent resistance and other characteristics. The following editor will take you to understand how the cold resistance of the spray molding material of the polyurethane foam machine equipment is.
Generally, it has good mechanical properties, high solid content, and good performance in all aspects. It is a kind of paint variety with great development prospects. The main application directions are wood coatings, automotive repair coatings, anti-corrosion coatings, floor coatings, electronic coatings, special coatings, etc. The disadvantage is that the construction process is complex, the construction environment is very demanding, and the paint film is prone to defects.
One-component polyurethane coatings mainly include urethane oil coatings, moisture-curing polyurethane coatings, and closed-type polyurethane foaming machine coatings. The application surface is not as wide as two-component coatings, mainly used for floor coatings, anti-corrosion coatings, pre-coil coatings, etc., and its overall performance is not as comprehensive as two-component coatings. The varnish variety of polyurethane paint is called polyurethane varnish.
Polyurethane foam is divided into soft foam and hard foam. They have different structures and different uses. The function of soft foam is to cushion, which can be used to make sofas, cushions and other automotive interiors, while the function of rigid foam is to keep warm and waterproof, and is often used to assist. Insulation of building boards, thermal insulation walls. The application of polyurethane foam is very extensive, and it is an indispensable material in many industries, and the equipment used to complete the process of polyurethane foaming machine is high-pressure polyurethane foaming machine, so the importance of the use of polyurethane foaming It goes without saying.
The overall layout of the equipment fully considers the utilization of space. Even after accommodating multiple sets of thermal insulation pipe groups, the designed moving space can still be guaranteed, and one operator can push and pull the equipment. The realization of the large-capacity carrying function of the equipment insulation pipe group increases the applicability of the polyurethane foam equipment, which greatly facilitates the operator, which not only saves manpower but also improves efficiency
