What are the types of polyurethane equipment?

Polyurethane equipment is divided into what kind of equipment? Polyurethane spraying machine, polyurethane high-pressure spraying machine, foaming machine, polyurethane foaming machine,Polyurethane high pressure foaming machine

  Sprayers, spray technology is the use of a special coating device, the principle of which is to promote the reverse of the airflow control valve reversing device, which causes the piston pneumatic motor to move steadily continuously back and forth. Pressurized spray through a high pressure hose is transmitted through a spray gun to the machine gun paint object after the release of the painting at the moment of inhalation of the paint is painted on the surface. The sprayer consists mainly of a feed device, a spray gun, and a composition of spray sources. Suitable for leather handbags, gift packaging, furniture, shoes, automobile manufacturing and other industries.

Polyurethane high pressure foaming machine

  

Spray polyurethane foam and include direct spray of polyurethane primer and synthetic resin, for example in two parts spray. Primers and a synthetic resin are used for direct spray of corrosion resistance, seal, insulation, etc., characterized by good wear resistance, excellent erosion, spray from 25 microns to several millimeters can be formed without spray suspension flow phenomenon.

Spray polyurethane, polyurethane high-pressure spraying equipment. Because of the high speed impact of the materials high-pressure spraying equipment in the violent mixing chamber and the small rotating space, the mixing is very good. The material in the muzzle of the formation of droplets of fine mist high-speed movement, evenly sprayed on the surface of the object.

Polyurethane spray foam is mainly used for insulation, in refrigeration insulation seal, not easy to use mold, such as coated large spherical storage tank, large diameter pipe, cold storage wall and other insulation materials can achieve foam.

  

High-pressure foaming machine is widely used, mainly used in sponge, soft foam, refrigerator, refrigerator, water heater, disinfection cabinet, solid wood furniture, pipe insulation, automotive interior decoration, storage board, mobile cabin, seats, sponge, toys and other products to fill the production of insulation materials.

The foaming agent is a certain concentration of aqueous solution when the foaming machine reaches the foaming equipment. Foaming agent itself can not automatically become foam, mechanical action must be through to become foam machine foam.

Polyurethane foam is a polyurethane foam machine perfusion foam equipment. Only the component polyurethane raw material (part of the isocyanate group with polyether polyols) is in accordance with the required performance index of the formulation. Through this equipment, uniform and qualified foam products can be produced. It is based on polyether polyols, and the presence of polyisocyanates in foaming agents, catalysts, emulsifiers and other chemical additives, prepared by chemical reaction foaming foam. Polyurethane foam machine can be used in automobile interior decoration, exterior wall insulation coating, insulation pipe manufacturing, bicycle and motorcycle cushion sponge processing.
