The development status of automotive filter paper at home and abroad
2020-03-17
Auto filter paper is one of the main material production car filter, also known as three auto filter, air filter, oil filter, fuel filter, it is a resin impregnated filter paper, on the filter production line after partial pressure, pressure wave and spread to curing process made filter, such as the internal combustion engine, such as automobile, shipbuilding, tractor, have the effect of the "lung" of the car engine, to remove the impurity in the air, oil and fuel oil, prevent wear of engine parts, prolong its service life. There are many filter materials for filters, such as cellulose, felt, cotton yarn, non-woven cloth, metal wire and glass fiber, etc., which are now basically replaced by resin impregnated paper filter element. With the rapid development of the world's automobile industry, filter paper as the filter material has been widely accepted and adopted by the world's automobile filter industry. As early as 2004, the United States has listed automotive filter paper as one of the ten most promising paper types in the world. In recent years, China's automobile production and sales have been advancing by leaps and bounds, increasing by 10 million each year. By 2009, more than 100 million cars have been possessed. In 2009, China's auto output reached 13.79 million units, up 48.3% over the previous year. In 2009, the sales volume of automobiles reached 13.65 million units, an increase of 46.1% over the previous year. Therefore, the demand for automotive filter and matching the filter paper is very large, and even multiply, automotive filter production has good prospects for development, market potential is tremendous, especially the air filter and fuel filter paper market demand is more outstanding, prompted the rapid development of automobile filter paper production enterprises in China and growing.
1, the current situation of foreign auto filter paper the development of the auto filter paper is closely related to the development of automobile industry, as early as 6 0 18 years American hayes special materials company (now the HV company) began to research and development of new products such as automobile filter paper, after more than 10 0 years development and production, now has formed annual output of more than 20000 tons, more than 10 0 varieties of multinational companies. South filter paper factory, an American scientific company, is also one of the largest automotive filter paper manufacturers in the world, with an annual output of more than 10,000 tons of automotive filter paper. Germany's GE S SNER and Italy's BOS SO both produce more than 10,000 tons of filter paper a year, mainly for the European and Asian markets. Britain prirestraint paper company, Germany ostrom company, is also Europe's larger automotive filter paper production plants, the annual output is also more than 8,000 tons, mainly for the European market. Japan's apo paper company and South Korea's aosilong company are the largest automotive filter paper manufacturers in Asia, with an annual output of more than 10,000 tons, mainly for the Asian market. The above eight big company is currently the world's largest automobile filter paper production enterprises, their production accounted for more than 70% of the total world auto filter paper, particularly striking is the multinational corporation has the production base to start off to the emerging developing countries, especially to places such as China, India, Brazil, the United States H V to China suzhou industrial park to establish a joint venture company, namely hayes (suzhou) specialty materials co., LTD., Japan, papermaking companies built solely invested enterprise in Shanghai, the British pury restraint paper company and shandong binzhou darfur paper set up a joint venture company. All these multinational companies landing in the Chinese market, the development of China's automotive filter paper industry, for many domestic automotive filter paper factories, is not only challenges and competition, but also promote and improve. Our domestic filter paper factory only do big, strong, do fine, take the development road of cost performance, difference, can compete with these foreign companies.
The research and development of automotive filter paper in China started relatively late. It was first developed by Shanghai guofeng paper factory and Shanghai paper research institute in 1960. and it was successfully trial-produced in 1965. its success marked the beginning of the production of automotive filter paper in China. However, this is more than 10 years behind the European and American countries. Along with the in-depth development of reform and opening up, especially in recent 10 years, the popularity of the rapid development of the automotive industry and household cars, greatly stimulate led to the rapid development of automobile filter paper so far on the normal production and scale of domestic enterprises and the products are: hangzhou xinhua paper industry co., LTD. "double circle" brand filter paper, special paper industry co., LTD. Hangzhou "nova" brand filter paper, shandong pury foote paper co., LTD., flicker "bamboo" brand filter paper, guangdong yuan to build special material technology co., LTD., suzhou new paper co., LTD., etc., product total annual output of around 13000 tons. At present, the number of automobiles in China has reached more than 100 million, so the demand for consumable filters of automobiles will increase in a straight line, and the demand for the corresponding automobile filter paper will naturally increase exponentially. The total domestic demand of automotive filter paper reaches 50,000 tons. However, the high-grade filter paper and the filter paper supporting the host machine mainly rely on the import, which will reach more than 20,000 tons annually. The products are mainly provided by H V company of the United States and osilon company of South Korea. With the rapid development of automobile industry, automobile will be popularized as individual consumption in the future, and consumers' understanding of vehicle maintenance is constantly deepened. As the main filter component of maintenance engine, it is more critical. Therefore, with the change of consumers' cognition, the requirements will be higher and higher. The development experience of many developed countries in Europe and America has proved this fact. On the contrary, the existence of poor quality, low grade automotive filter paper in the existing maintenance market will become smaller and smaller.
At present, the gap between the automotive filter paper produced by domestic enterprises and that produced by international advanced enterprises is mainly reflected in the following aspects:
(1) low filtration efficiency, poor filtration accuracy and low dust tolerance, resulting in short service life;
(2) the performance of temperature, water and oil resistance is not as good as that of imported products, resulting in short service life;
(3) the quality fluctuates greatly and the stability is poor. Here needs to point out specially is: the country still has dozens of small-scale filter paper factory, the filter paper that these factory produces basically USES kapok, waste cotton, a few wood pulp is raw material, need not mercerizing pulp basically. Glue resin with starch is given priority to, used to produce filter paper porosity is low, basic no broken degrees poor resistance, water resistance, filter paper immediately encounter water or water vapor deformation taken away, even together will cause no permeability and filterability, serious impact on the normal operation of the car engine, and bring serious security hidden danger to the car moving. This kind of filter paper has already been eliminated in foreign countries, because there is no corresponding unified standard and standard in China, the products of this kind of small-scale enterprises are shoddy and cut corners, which are largely filled in all kinds of low-grade maintenance market. This to our country filter paper and the development of the corresponding filter industry is very adverse, we must cause enough attention, the best by the industry association to rectify, improve. Domestic paper compared with imported filter paper in the domestic automobile filter paper manufacturer home, it is worth mentioning hangzhou special paper industry co., LTD., since 20 02 years development and production of automobile filter paper, draw lessons from, the introduction of foreign mature technology, and work closely with domestic related research institutes, the road of development of resin with their characteristics and filter paper production road, just a few short years 3 production lines have been put into operation, curing filter paper on the new production line has 2010 formally put into production in August, the annual output has reached 70 0 0 tons, varieties available, machine filter, diesel filter, air filter, curing wrinkles, flame retardant filter paper, filter paper filter paper, etc. Series of products, Best-selling domestic form a complete set of more than 100 cooperative enterprises, some products are exported to foreign countries, is currently the industry many varieties, complete specifications, price, service good well-known enterprises, is currently targeting international peers first-class enterprise, benchmarking for reference, the introduction, digestion, absorption and innovation, continuous development and production of high precision, good filtration efficiency, long service life, optimal ratio of filter paper series products.
3. The quality of the domestic and foreign automobile filter paper contrast production car filter air filter, main is to protect the engine cylinder and piston ring to prevent abrasive wear, if the air filter filtering effect not beautiful, also can have a lot of dust into the cylinder, the piston ring gap into the crankcase oil, increasing the crankshaft journal and bearing wear and tear. Air filter performance is good or bad, on the one hand, and the structure of the air filter itself (including filter processing quality), on the other hand is the key to the filter paper adopted by the quality, for air filter paper, the first requirement is good permeability, to ensure that the filter resistance is low, the second is the porosity should be appropriate, in order to make sure there is enough high filtration efficiency and filtration fineness. These two requirements are contradictory, reducing the filter paper aperture can improve the filtration efficiency, but the resistance of gas is bound to increase, which requires different specifications of filter paper to meet different requirements of the filter. Here, the quality of air filter paper is taken as an example to reflect the quality difference between domestic filter paper and imported filter paper. See table 1. As can be seen from table 1, the original filtration efficiency of filter elements made by imported filter paper #1 and #2 is 99.71% and 99.79%, respectively, and the filtration efficiency of lifetime is 99.34% and 99.66%, respectively. The original filtration efficiency of domestic filter paper made in #1 and #2 is 98.57% and 98.65% respectively, and the lifetime filtration efficiency is 98.93% and 99.08% respectively. The original filtration efficiency and lifetime filtration efficiency of domestic filter paper produced are lower than that of imported filter paper. In short, China's vast land, climate change, host variety, power size is different, the need for supporting filters are also different, so we need to filter paper manufacturers and filter manufacturers closely cooperate, produce a better series of products, to meet the needs of the development of the automotive industry.
