Embodiment 1

[0017] At 125°C-135°C, the weight-average molecular weight is 100,000-120,000, and the density is 0.94-0.965Kg / m 3 A hollow plastic ball of Φ15mm×1.5mm made of high-density polyethylene. Then, the perfluoroalkoxy benzoic acid with a weight average molecular weight of 150,000 to 180,000 is treated on the surface of the hollow plastic bead by vacuum evaporation and vapor layering. The process flow is: pre-treatment of vacuum evaporation (cleaning the surface with absolute alcohol, drying at 50°C and eliminating static electricity) - vacuuming (controlling the pressure at 10 -3 ~10 -2 Pa) - ion bombardment - bake evaporation. Finally, a layer of dense and defect-free 5-10 μm perfluoroalkoxybenzoic acid molecular film is formed on the surface of the hollow plastic product. Put the fluorinated hollow plastic products into the oil tank one by one, and cover the surface of the light fuel oil to suppress the evaporation loss of the oil. Compared with the storage tank without the so...

Embodiment 2

[0019] At 150°C-160°C, the weight-average molecular weight is 50,000-200,000, and the density is 1.35-1.45Kg / m 3 Polyvinyl chloride (PVC) made of square hollow plastic products with a side length of 20mm and a thickness of 0.5mm. Then the relative molecular weight is 38, the density is 1.696Kg / m 3 , the high-purity fluorine gas with a purity higher than 99% is slowly passed into the fluorination furnace for fluorination of hollow plastic products. The reaction time is controlled at 48-72 hours, and the amount of fluorine gas introduced is 15-25Kg / m according to the surface area of ​​the treated plastic. 2 Prepare the amount, and finally form a layer of dense and defect-free 5-20 μm fluorine-containing molecular film on the surface of the hollow plastic product. Put the fluorinated hollow plastic products into the oil tank according to a certain thickness, and cover the surface of the light fuel oil with a layer to inhibit the evaporation loss of the oil. Compared with the sto...

Abstract

The present invention discloses one kind of soft floating roof tank for controlling the evaporating loss of light fuel oil. The technological scheme includes the first surface fluorating treatment of oil resistant hollow plastic products in different sizes and shapes and the subsequent throwing the treated plastic products into the oil storing tank, so that the plastic products can float to cover the oil surface, reduce the free evaporating surface area and inhibit the evaporating loss of light fuel oil. The present invention is suitable for various kinds of light fuel oil tank of different shapes.

Description

technical field [0001] The invention relates to a technology for controlling the evaporation loss of light fuel oil, in particular to a soft floating roof oil tank technology for controlling the evaporation loss of light fuel oil. Suitable for suppression of evaporation loss of light fuel oil in storage tanks of various shapes. Background technique [0002] Petroleum and its products, as the country's important strategic materials and non-renewable energy sources, occupy a very important position in the country's economic construction and national defense construction. The evaporation loss of oil products accounts for 76% of the total loss of storage and transportation systems, which not only causes economic waste, but also affects the quality of oil products and causes environmental pollution. Contents of the invention [0003] The purpose of the present invention is to provide a soft floating roof oil tank techno...
