However, the export value of auto parts in the total auto exports is still a large contribution, accounting for 74.31% of total auto exports, it is worth mentioning that in 2012 China's auto parts import and export trade surplus reached $246.89 billion. , $3.519 billion more than the previous year. In terms of imports, the rate of decline in the past has dropped, and this has directly presented a declining trend. In 2012, the cumulative amount of auto parts imports totaled 30.633 billion U.S. dollars, a year-on-year decrease of 1.26%.
The lack of high-tech high-tech products with high added value and low-tech products has always been the weakness of domestic auto parts exports. The reporter teased out the export data since 2006 and found that in the seven years of China’s auto parts exports, although the export volume has grown rapidly, there has been almost no fundamental change in product structure, with high energy consumption, high consumables, and low-tech value-added products. Still occupy the mainstream, such as tires, brake linings, wheels, etc., and most of them are exported in general trade.
The engine, transmission and other high-tech automotive electronics products account for a very small percentage of exports. Taking the engine as an example, 2011 was the best year for its export performance, with a total of 429.28 million units exported, a year-on-year increase of 29.05%, and an export value of 1.769 billion US dollars, an increase of 79.60% year-on-year, but compared with China’s auto parts production of US$52.193 billion. Compared with the total amount of exports, it is still insignificant.
What's more unfortunate is that engine exports failed to continue the splendor of 2011 in 2012. In the whole year, it exported a total of 315.18 million units, a year-on-year decrease of 26.58%, and the export value was 1.486 billion US dollars, a year-on-year decrease of 15.97%. Of course, engine imports in 2012 were also sluggish. Last year, engine imports reached 738,300 units, a year-on-year decrease of 337,700 units, and the amount of imports was 2.265 billion US dollars, a year-on-year decrease of 26.99%. Among them, varieties with more than one liter all showed significant declines.
From the data point of view, automobile and motorcycle tires and other automobile-related goods have grown rapidly. The export value of automobile and motorcycle tires was US$14.47 billion, an increase of 7.78% year-on-year, and that of other automobile-related commodities was US$11.489 billion, a year-on-year increase of 16.47%. The export value of auto parts, accessories and auto bodies was US$27.877 billion, an increase of 2.74% year-on-year.
The lack of high-tech, high value-added products is also not uncommon in regional exports. For example, in Shandong Port, the brakes for vehicles and their parts turned out to be the largest export goods for local auto parts. In 2012, Shandong Port exported brakes and its parts for motor vehicles to US$1.1 billion, accounting for 39.4% of the total value of auto parts exports in the region.
The lack of large-scale leading export companies has a large number of export enterprises, but the average export amount of each company is small, and it is the embarrassment of China's auto parts exports for many years. According to statistics from the China National Automobile Association Wheel Committee in 2012, China’s exports of aluminum wheels last year were only 377 million U.S. dollars, 175 countries and regions were exported, and 3,426 enterprises were involved in export. The fierce competition and the disorder of export order Can imagine.
There are several auto parts companies with an annual export value of more than 100 million U.S. dollars. How was the value of exports worth 55.322 billion U.S. dollars accumulated in 2012 due to the insignificant sales of many parts and components companies? The reporter is not yet able to learn from official data. However, it is certain that, for most auto parts companies, the order in the overseas market is only a temporary purchase and sale of the company. This idea is widespread and it is not an export to auto parts. Good things.
Furniture edge sealing glue can be divided into three categories according to the different base materials:
EVA (ethylene-vinyl acetate copolymer resin) base material hot melt adhesive, this hot melt adhesive can be divided into two types with filler and without filler. Using EVA as the base material is the most common production technology for furniture edge sealing adhesives, and its main limitation is poor heat resistance. The ambient temperature of panel furniture sealed with EVA hot melt adhesive shall not be higher than 120°C;
POL YAMIDE (polyamide) based hot melt adhesive, this hot melt adhesive has good heat resistance and fast curing characteristics, the main disadvantage is that it is expensive.
HMPU (polyurethane) base material hot melt adhesive, it is a kind of hot melt adhesive with the best performance, and it is the guarantee of high quality sheet edge sealing. It is expensive and requires special usage.
The performance of furniture edge sealant
1. Viscosity of furniture edge sealant
The viscosity of furniture edge sealing glue does not directly reflect the performance of the glue. In general, the higher the viscosity of the furniture edge sealant, the better its initial tack strength, but the worse the coating performance. Low-viscosity hot melt adhesives have a smaller amount of glue and better wetting properties. Some hot melt adhesives with low viscosity and fast curing speed may also have high initial tack strength.
2. Density of furniture edge sealing glue
The density of furniture edge sealant is generally 0.95-1.6g/cm3, and its density depends on the amount of filler.
3. Softening point and use temperature of furniture edge sealing glue
The softening point is an indicator of the heat resistance of the furniture edge sealant. The higher the softening point, the less likely the furniture edge sealant will melt. At the same time, softening point is also an important aspect to measure the temperature resistance of panel furniture.
4. The opening time of the furniture edge banding glue and the feeding speed of the edge banding machine
Furniture edge sealant is widely used in the market because of its solvent-free, water-resistant, and environmental-friendly features.
