Polyurethane foaming machine is the black material (isocyanate, also called crude MDI) and white material (combined polyether) are fully mixed according to a certain ratio (the conventional ratio is 1:1) Combine the output, the two raw materials after the output react chemically, start to expand and foam, and finally A foam foam with uniform and closed cell holes is formed.
Features:
According to the spraying state of the raw material from the nozzle of the polyurethane foaming machine, it is classified into spraying patterns and pouring patterns;

Spray polyurethane foam machine use:
Insulation and waterproofing of building exterior walls and roofs-integration, cold storage, grain storage, chemical plant storage tanks and pipes, etc.
Use of infusion polyurethane foaming machine:
Solar water heater barrel, insulated water tank, stainless steel water tank, car portable refrigerator, beer barrel, anti-theft door, cabinet, plate, on-site foam packaging, aluminum profile cavity, etc.
Polyurethane foaming machine is widely used in multi-mode continuous production of rigid and semi-rigid polyurethane products, such as: petrochemical equipment, directly buried pipelines, cold storage, water tanks, meters and other thermal insulation and sound insulation equipment and craft products
As a new coating material, polyurea has changed the concept and cognition of previous coatings by engineers and added new knowledge of coatings. Since the polyurea coating can withstand the full impact of a sledgehammer and the most severe abrasion, it also has satisfactory flexibility. When the obv
What are the reasons for the unstable flow of the variable pump of the multifunctional high-pressure foaming machine? If you want to know, please come and find out with the editor!1. The input port of the variable pump of the multifunctional high-pressure foaming machine is lacking in supply. It may
There are many kinds of fillers used in polyurethane rigid foam, such as expanded graphite, powdered nylon, silica, glass fiber, etc. The filler used in polyurethane foam must be dried before use. When applied to a water foaming system, its moisture content must be measured.
1. The company's equipment has passed CE, ISO9001 quality management system certification, completely independent intellectual property design and production, has declared a number of national invention patents.2. The equipment is small in size, light in weight, low in failure rate, convenient to mo
The key to the construction quality of spraying polyurea lies in the substrate, and the substrate is divided into two types: metal substrate and concrete substrate, but no matter which kind of substrate, we must consider its anti-corrosion and waterproofing. So, what are the ways to deal with the an
Construction efficiency and characteristics of polyurea spray equipmentConstruction characteristics of polyurea spraying equipment: Polyurea spraying equipment is mainly used for spraying of rough spots on the surface of interior and exterior walls of buildings, spraying of commercial mixed polyurea
At present, the advantages of rigid polyurea with its excellent physical and chemical properties and advanced and convenient construction technology in the anti-corrosion application of the outer wall of the pipeline have been highlighted. Compared with 3PE, the rigid polyurea spraying equipment has
Polyurea spraying equipment is a highly reactive and pollution-free spraying technology developed in the past 20 years abroad. Its excellent physical and chemical properties, excellent manufacturability and environmental protection fully show its unparalleled superiority over traditional protection
With the improvement of our quality of life, various scientific and technological building materials in our lives also appear in our daily buildings. Spray polyurethane is one of the more practical materials. Polyurethane is a kind of insulation and waterproof coating. Among them, its thermal insula
