Technical Field

The invention belongs to the technical field of heat insulation material production, and particularly relates to a processing device for producing a refrigeration house plate.

Background

The refrigeration house plate (polyurethane insulation plate) has the following advantages: 1. the hard polyurethane has low heat conductivity coefficient and good thermal performance; 2. the hard polyurethane has the moisture-proof and waterproof performances; 3. the hard polyurethane is fireproof, flame retardant and high temperature resistant; 4. strong deformation resistance, difficult cracking, stable and safe facing. Because the polyurethane heat-insulating board has excellent heat-insulating property, the thickness of an outer enclosure structure of a building can be reduced under the condition of meeting the same heat-insulating requirement, so that the indoor use area is increased, and the polyurethane heat-insulating board is applied to building wall materials. Meanwhile, the polyurethane insulation board is widely applied to the fields of cold rooms, insulation boxes, chemical pipe bodies and the like. Since the polyurethane foam layer is formed by curing the polyurethane foam, it is necessary to provide a foaming machine for the polyurethane foam. The conventional polyurethane foaming machine has a problem in mixing and proportioning of black materials and white materials, and the black materials refer to isocyanate parts such as 5005 of Hensman, Wanhua PM200 made in China and the like. The white material mainly refers to a polyol part and polyether products with more brands, and is produced by domestic large factories such as high bridge petrochemicals. The black and white materials are called in the polyurethane foaming industry. The proportion has great influence on the foaming material, and if the proportion is not proper, the foaming plate is too soft and easy to crack.
