Problems solved by technology

[0004] However, the disadvantages of the current anti-explosion materials are that the material has large internal crystals, is not compact, hard and brittle, has no toughness and elongation, and is easy to break and drop slag.
Moreover, if the entire mesh is pressed with a little force, the debris will be thrown all over the ground, seriously blocking the oil circuit of the fuel tank, which is very inconvenient to use, often causing the oil circuit to fail to ignite, seriously affecting the quality
When you put it in the fuel tank, it will block the oil gauge and can't turn it
The amount of oil can not be accurately measured, causing inconvenience to customers, clogging the oil gauge and not being able to rotate. Overcoming the above defects has been an urgent problem to be solved by various countries for many years.

Embodiment Construction

[0019] The present invention adopts: the weight percentage of the chemical composition of the anti-explosion material is Si0.1~0.6, Fe0.2~0.7, Cu0.05~0.1, Mn0.6~1.2, Zn0.05~0.1, Ti0.03~0.12, Na0 .02~0.07, Al balance. The production method is as follows: put the explosion-suppressing material with the above chemical composition into a melting furnace and heat it at 700°C to turn it into a liquid state, and the liquid state stays at 700°C for 1 hour; the above liquid material is deslagged and degassed by nitrogen purification method (a traditional method), After standing still for 0.8 hours, pour it into the crystallizer to cast a ton of blank; after cooling, mill the blank with a scraping machine, the thickness of the milled surface is 0.1 ~ 1mm, to keep it pure; put the blank after milling into the annealing furnace Heating to 360°C and holding for 5 hours to complete the first annealing and two processes; then use the hot-rolling method to heat the annealed billet at a temper...

Description

technical field [0001] The invention belongs to a production method of explosion suppression materials. Background technique [0002] Explosion suppression material is a functional material installed in the storage container of flammable and explosive fluid, which can prevent the combustion and explosion of flammable and explosive fluid. Explosion suppression materials can be divided into organic compound foam materials, metal foam materials and honeycomb mesh materials according to their types. [0003] As early as the 1960s, the United States developed polyurethane foam explosion suppression materials, which are mainly used for the safe storage and use of oil products. However, the chemical stability of this material in oil is very poor, and it is easy to crack and break, causing oil pollution and even blocking the oil circuit, so it will be eliminated after only 2 to 5 years of use. Since then, the relevant departments of the United States and Canada have jointly succes...
