Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of polyurethane, in particular to a uniformly mixed polyurethane high-pressure foaming machine. Background Art
[0002] Polyurethane is an important chemical substance, which is usually used as an ingredient in materials or coatings. It is a polymer compound formed by the reaction of isocyanate and polyol. This material has strong toughness and wear resistance, so it is widely used in the manufacture of various products such as automotive parts, furniture, soles, insulation materials, etc. In terms of coatings, polyurethane is also used to apply on the surface to provide protection and decorative effects. Polyurethane high-pressure foaming machine is a device used to make polyurethane foam materials. It usually uses two chemicals (polyisocyanate and polyol) mixed under high pressure and sprayed into a mold to produce foam materials through chemical reactions. This equipment can be used to produce insulation materials, filling materials, insulation materials and other similar products. It is widely used in construction, industry and manufacturing.
[0003] When the high-pressure foaming machine is foaming, the polyurethane material needs to be mixed evenly. The existing stirring and mixing mechanism can only stir the polyurethane material in one direction, which will cause some materials to gather together, while other materials may not be fully mixed. In addition, during the mixing process, some materials will adhere to the inner wall of the mixing mechanism, making it impossible to discharge them. Uneven mixing may cause an imbalance in the chemical composition ratio of the polyurethane foam material, reducing the mechanical properties and service life of the foam material.
