Embodiment Construction
[0023] The present invention relates to a double-layer oil tank penetration process, the process includes the following steps:
[0024] Step 1. Spray large-diameter particles on the cylinder and head of the iron inner shell, and the particle diameter is 0.5-1mm;
[0025] Step 2: Wrap polyester film on the cylinder of the inner shell, and wrap a stretchable wrapping film on the curved surface of the head, so as to form a middle layer penetration gap with leak detection function as a whole with the large-diameter particles;
[0026] Or, lay 3D three-dimensional fabric on the cylinder body and the head at the same time, so as to form an interlayer penetration gap with large-diameter particles with leak detection function;
[0027] Alternatively, a 3D three-dimensional fabric is laid on the cylinder, and a stretchable stretch film is wound on the curved surface of the head. The 3D three-dimensional fabric and the stretch film together form a middle layer penetration gap with the f...

Abstract
A penetration process of a double-layer oil tank of the present invention includes the following steps: step 1, spraying large-diameter particles on both the cylinder body and the head of the iron inner casing, step 2, winding the cylinder body of the inner casing The polyester film is wound, and the stretchable film is wound on the curved surface of the head, so as to form an intermediate layer through gap with leakage detection function with the large-diameter particles; Form an intermediate layer through gap with leak detection function with large-diameter particles; or, lay 3D three-dimensional fabric on the cylinder body, and wrap a stretchable wrapping film on the curved surface of the head. The intermediate layer through-gap with the function of leak detection is formed under the support of the device; step 3, the outer casing is made by resin vacuum diversion. The invention relates to a penetration process for a double-layer oil tank, which has the advantages of simple process, high efficiency and good penetration effect.
Description
technical field [0001] The invention relates to a preparation process of a double-layer oil tank, in particular to a preparation process of an intermediate layer of an FF double-layer oil tank. Background technique [0002] With the rapid development of the domestic economy, the problem of environmental protection is becoming more and more prominent. The conventional single-layer iron oil tanks in gas stations have hidden dangers of environmental pollution due to leakage; for this reason, a new double-layer oil tank needs to be used to replace them; but the conventional In the preparation engineering of double-layer oil tanks such as FF, the preparation of the middle part which plays the role of leak detection is a difficult problem, which often consumes a lot of manpower and material resources, and can not guarantee the true penetration. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a double-layer...
