Polyurethane material for top car materials
According to the latest statistics, as of August 2015, the domestic production capacity of polyurethane raw material MDI (diphenylmethane diisocyanate) has soared to 3.02 million tons per year. The consumption of polyurethane materials for automobiles is in a stage of rising.
The increase in polyurethane consumption is inseparable from the increase in sales in the global automobile industry. According to incomplete statistics, my country's automobile sales reached 23,491,900 in 2014, a year-on-year increase of 6.86%. In the plastics used in modern automobile materials, the amount of polyurethane is not only the largest, but also its application range is unparalleled, from the car box to the outer parts, from soft to hard, from light to dense, all the way to high High-strength glass fiber reinforced products, polyurethane applications can be seen everywhere.
The polyurethane material for automobile roof is the most demanding among all polyurethane materials for vehicles, especially now it needs to be combined with a duct folding machine to meet the hardness and rigidity requirements of the substrate during the hemming process of the duct folding machine.
Polyurethane foaming machine can process polyether polyol and isocyanate materials to support uniform and qualified foam products, but how to better improve the function of the equipment will be an important prerequisite for improving the quality of foam products. Of course, to process the polyureth
Shandong Hightop Group conducts all-round disinfection work for Aile Kindergarten in Jining High-tech Zone for free The Spring Festival in 2021 is approaching. In order to effectively eliminate the virus and prevent the spread of the epidemic, Shandong Hightop Group launched a public welfare activit
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
