The development of aluminum vehicles in Europe and America has a history of more than 30 years. Currently, the penetration rate of aluminum semi-trailers reaches 70%, while the domestic aluminum transportation products only account for about 1% of the freight market. Research on aluminum semi-trailers also In its infancy. In the past two years, the domestic aluminum semi-trailer manufacturers have emerged, such as Yutong Motor Company, Jungle Motors, and Yuli Industry, but the market sales situation is not clear.
The author tries to analyze why the European and American aluminum semi-trailer develops so quickly:
The excellent properties of aluminum alloy help energy conservation and emission reduction:
Aluminum alloys have a series of excellent properties, such as low density, light weight, high strength, good elasticity, good impact resistance, corrosion resistance, easy surface coloration, good processability and high recovery and regeneration, etc. The aluminum alloy reduces the total mass of the vehicle, thus reducing the fuel consumption. Due to low fuel consumption, light weight, and low exhaust emissions from the vehicle, the pollution level decreases; the recovery rate of used vehicles is high, and aluminum automotive parts are basically recyclable. Less energy is needed for recycling, and aluminum can be recycled many times.
In the coming decades, aluminum is the most desirable metal structural material for reducing transportation costs, saving energy, reducing greenhouse gas emissions, developing a recycling economy, and improving transportation efficiency. The purpose of lightweight aluminium semi-trailers in foreign countries is to reduce fuel consumption, energy conservation and emission reduction, while domestic lightweight aluminum vehicles have taken into account some of the issues of weight-based charging, which has caused the slow popularity of domestic aluminum semi-trailers to some extent.
Foreign governments to improve fuel standards strict exhaust emissions:
One of the important reasons for the popularization of aluminum semi-trailers abroad is the government’s policy orientation. Under the pressure of energy shortage and environmental pollution, the government requires auto manufacturers to raise fuel standards and energy-saving emission reduction standards, and promote the legalization and standardization of industry development. The advantages of lightweight aluminum alloys have led to the development of lightweight technologies and products in automotive manufacturing. Aluminum semi-trailers have been widely used.
In China, the national IV emission standard of the fourth phase of the national vehicle pollutant emission standard will be implemented step by step. In terms of emission control, the national IV standard vehicle needs to further reduce the pollutants by 30% to 50% on the basis of State III. Up to standard. At present, only the Beijing, Shanghai and Pearl River Delta regions in the Mainland implement this standard. In contrast, the import of heavy-duty trucks in the Chinese market has reached the national IV standard.
According to the development experience of European and American aluminum semi-trailers, the domestic aluminum semi-trailer manufacturing will have a lot of room for development. It needs to be strengthened from government policies, technology research and development, and popularization, narrowing the gap, and truly meeting the standards for energy saving and emission reduction. .
1. Introduction
The Hot Melt Adhesive For Furniture is a kind of adhesive specially used for artificial plate paste, which is an environmentally friendly and solvent-free thermoplastic adhesive. When the hot melt adhesive is heated to a certain temperature, it is transformed from a solid state to a molten state, and when it is coated to the surface of the wood-based panel substrate or edge sealing material, it is cooled into a solid state, and the material and the substrate are bonded together.
2. Ingredients
The basic resin of hot melt adhesive is the copolymerization of ethylene and vinyl acetate under high temperature and pressure, that is, EVA resin. This resin is the main component of the production of hot melt adhesive, and the proportion and quality of the basic resin determine the basic properties of hot melt adhesive.
3. Application
More and more varieties of hot melt adhesive, more and more widely used, can be bonded leather, glass, metal, wood, luggage plastic, medical, textiles, etc., but mainly used in packaging corrugated paper and thick cartons, books wireless binding and woodworking welt.
