浸滲技術的古代應用（含浸技術的由來）The ancient application of Infiltration technology (including the origin of infiltration technology)：
In fact, infiltration technology is not the first to be used in modern society. In ancient times, people have already started to use infiltration technology to carry out production activities. Although the purpose of its use is different from that of modern infiltration, it should be the oldest infiltration technology. But we have to admire the wisdom of our ancestors.
1、最典型的古代浸滲技術是切割巨大巖石技術The most typical ancient infiltration technique is the cutting of huge rocks：
There were no rock cutting machines in ancient times, so how were the huge rocks used for buildings and decorations cut? Actually since ancient times, people began to master the simple impregnation technology and its principle, on the big rock to open some dry stick into the hole, the hole people by using the theory of infiltration microporous absorb water through the dry sticks sticks, the rods began to swell, as we all know wood imbibe its inflation pressure is very big, It expands with so much force that it cracks the rock, and in this way it cuts the rock. The use of dry wood to absorb water expansion, this should be the oldest infiltration technology.
2、防止木制品變形的木材浸滲技術Wood infiltration technology to prevent deformation of wood products：
Wood products due to dry or wet and expansion shrinkage deformation, such as tool wooden handle, tool handle and other wood products deformation and loose, wood deformation. To solve this problem, people made wood products with resin infiltration into the interior, thus solving the problem. The purpose of this infiltration is the same as that of modern wood infiltration, which is still used today.
浸滲技術的當代應用Contemporary applications of infiltration technology
1、防止軍用飛機的鋁合金鑄造零件微孔泄漏Prevent the microhole leakage of the aluminum alloy casting parts of military aircraft：
The aircraft was successfully tested in 1905, and was used in World War I from 1914-1918, and in World War II from 1939-1945, metal aircraft were widely used.
The aluminum alloy casting parts on the metal plane are due to the existence of micro pores such as pinhole porosity and shrinkage that can not be seen by the eyes during casting. These are formed due to the gas produced by the aluminum alloy during casting and the original gas in the mold moving around in the material, or caused by cooling and shrinkage in the forming process.
Different characteristics, such as pinholes, may cause leakage from the inside of the component to the outside. Such as lubricating oil, grease, cooling water, gasoline, air, air conditioning refrigerant gas and other liquids and gases inside the shell of the parts will leak. In addition, moisture will infiltrate from the outside, which will affect or even damage the function of the components.
Therefore, it is necessary to carry out infiltration treatment. Infiltration treatment is to allow the liquid infiltration agent to penetrate into the inner pores of the casting, so as to solidify it, so as to prevent the occurrence of parts leakage, oil leakage and water seepage. The infiltration technology was applied to the military industry in 1940. Since it is an important production process in military production in the United States, the American military enterprise and military management department formulated the infiltration standard. After several updates, the updated infiltration agent standard is MIL-I-17563C, which is still in use today. The standard for infiltration treatment was MIL-STD-276A, which is still in use today.
2、軍用轉民用Military to civilian use：
Later, in the automobile, motorcycle, train, ship, air conditioning and other household appliances industry, water pump and pipe fittings and other hardware, such as pressure castings, gear and electronic parts, powder metallurgy parts are also widely used. In the mass production process of pressure die-casting parts, generally will produce about 8~ 50% of the parts leakage. If it is completely re-cast, it will cost a huge amount of money, so infiltration is widely used in private enterprises. Therefore, infiltration treatment plays a key role in quality assurance and reducing production costs, and has become a very important production process.
It is also widely used in electronic components and motor coil insulation, parts rust prevention, etc.
In addition to improve the physical properties of parts such as improving the cutting performance of parts to extend the service life of cutting tools has also been applied.
In addition, in the metal surface treatment such as electroplating, spray painting, plastic spraying process is also applied infiltration treatment, can improve the quality of electroplating, spray painting and plastic spraying, the surface is more smooth will not produce spots, bumps, and can extend the life of parts.
The company will continue to improve the production process and quality of products, and continue to develop new products to maintain market competitiveness. Is moving in the direction of the modern enterprise with time. "Sincere, pragmatic, high quality, efficient" for the purpose of the enterprise, dedicated to serve people from all walks of life.
