Obstruction and explosion suppression material aluminum foil of oil tank for gas station

Abstract

The invention discloses an obstruction and explosion suppression material aluminum foil of an oil tank for a gas station. The aluminum foil comprises the following components in percentage by weight: 0.4 to 0.8 percent of Si, 0.5 to 0.9 percent of Fe, 0.05 to 0.2 percent of Cu, 1.0 to 1.5 percent of Mn, 0.05 to 0.15 percent of Zn, 0.02 to 0.04 percent of Mg and the balance of Al. The aluminum foil has relatively high flexibility and tensile strength; the obstruction and explosion suppression material, which is used for preparing the aluminum foil, of the oil tank for the gas station has relatively appropriate softness and hardness; and residues and powder are prevented from falling and an oiling machine is prevented from being blocked when the aluminum foil is used.

Description

technical field [0001] The invention relates to an anti-explosion material, in particular to an aluminum foil of an oil tank barrier anti-explosion material in a gas station. Background technique [0002] The traditional production of aluminum foil is annealed once during the production process. In addition, the intermediate foil blanks between 0.3 and 0.45mm are hot-rolled finished products without annealing, that is, the H18 state, and the tensile strength is actually 250Rn / cNmm 2 In the above hard state, after the aluminum foil is punched into a net, it becomes brittle and foams off. [0003] The other is no intermediate annealing and finished annealing. That is the H26 status. Because there is no annealing in the middle. From the 7.0mm billet has been rolled to a foil thickness of 0.05mm. Rolled to 0.25 ~ 0.3mm. The annealing temperature is 300°C and the time is 16-20 hours. After changing the internal crystallization of aluminum, aluminum rolling is carried out. ...

AI Technical Summary

Problems solved by technology

[0004] Aluminum foil is used to make barrier and explosion suppression materials, and there will be the following problems: if it is soft and installed in the oil depot, the aluminum foil mesh will be formed by the pressure of the oil, and there will be no supporting force

If it is hard, it will drop slag and foam after making it into a net. When the fuel dispenser is working, the aluminum chips and aluminum foam deposited in the oil tank will block the gear parts of the fuel dispenser, making the fuel dispenser unable to work normally.
