Description

Technical Field

[0001] The invention relates to the technical field of special gas packaging, and in particular to an inner wall processing method for special gas packaging. Background Art

[0002] Special gases are gases that meet specific purposes, including single gases or mixed gases. There are 259 single gases, including 115 electronic gases, 63 organic gases, 35 inorganic gases, 29 halogen gases, and 17 isotope gases.

[0003] At present, special gas packaging mainly uses special gas cylinder packaging containers for packaging and transportation. With the increasing variety of corrosive and easily adsorbed standard substances, there are many standard gas cylinder manufacturers and gas cylinder varieties, including ordinary carbon steel cylinders, aluminum alloy cylinders, grinding bottles and coated bottles. In daily preparation, except for special coated bottles, general aluminum alloy and grinding bottles cannot meet the preparation requirements of specific varieties. The effect of carbon steel cylinders for preparing easily adsorbed standard substances is even worse, and carbon steel cylinders are usually not used for preparation. As far as current gas manufacturers are concerned, there are many cases where the preparation stability of gas products is poor. The user's use process directly affects the qualification of the product to be tested and the performance of equipment and facilities. To ensure the accuracy of standard substance measuring instruments, the key is to use packaging with good stability.

[0004] The prior art has the following problems:

[0005] The existing special gas packaging, except for the special coated bottles in daily preparation, the general aluminum alloy and grinding bottles cannot meet the preparation requirements of specific varieties at all. There are many gas products with poor preparation stability. The user's use process directly affects the qualification of the product to be inspected and the performance of the equipment and facilities. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a method for treating the inner wall of special gas packaging, which solves the existing problem of poor stability of special gas packaging.

[0007] To achieve the above object, the present invention provides the following technical solution: a method for treating the inner wall of a special gas packaging, comprising the following steps:

[0008] Step 1: Prepare the gas cylinder packaging container to be treated for inner wall spraying, spray the coating resin on it, and let it stand and dry at room temperature;

[0009] Step 2: Clean the inside of the prepared gas cylinder packaging container, remove the mechanical impurities inside and ensure that there are no attachments left;

[0010] Step 3: Use abrasive materials to grind the inner wall of the gas cylinder packaging container to ensure the flatness and smoothness of the inner wall;

[0011] Step 4: Clean the ground gas cylinder packaging container with deionized water, then with an aluminum alloy cleaning agent, and finally clean it again with deionized water;

[0012] Step 5: Prepare the vinyl composite material and add silicone material to it to prepare the coating;

[0013] Step 6: Apply the prepared coating to the inner wall of the gas cylinder packaging container by rolling, and ensure that it has good leveling properties;

[0014] Step 7: Place the coated gas cylinder packaging container at a suitable temperature for a certain period of time to dry it, and then take it out after the coating material is completely solidified. The overall inner wall treatment is completed.

[0015] In some of the embodiments, the inside of the gas cylinder packaging container is cleaned with a water gun, and the water pressure parameters of the water gun need to be adjusted. The water pressure must be lower than the tolerance threshold of the gas cylinder packaging container material. After cleaning, it is inverted to drain.

[0016] In some of the embodiments, the roller coating method needs to maintain a uniform coating speed, and during the roller coating process, it is necessary to ensure that no fish-scale or striped coating appears, maintain good leveling, and maintain the coating thickness at 3-4 microns.

[0017] In some embodiments, the suitable temperature and time are specifically 160 to 180 degrees for continuous drying for 2 hours. The drying equipment can be an industrial oven or a drying furnace, and the temperature control cannot exceed 200 degrees, otherwise the vinyl material cannot be used anymore.

[0018] In some embodiments, the specific materials of the vinyl composite material are 30% turpentine, 40% vinyl resin, 5% catechol, and 2% silicone resin, and the silicon material is specifically silicon dioxide.

[0019] Compared with the prior art, the present invention provides a method for treating the inner wall of special gas packaging, which has the following beneficial effects:

[0020] This is a method for treating the inner wall of special gas packaging. Through this method, a layer of special vinyl composite coating can be present inside the gas cylinder packaging container. This coating can ensure the stability of the preparation of standard gas when the gas is packaged, prevent the inner wall of the packaging from adsorbing gas components, and ensure the accurate preparation of standard substances. At the same time, the gas cylinder can be treated according to the preparation requirements of the customer, so that the customer does not need to purchase special gas cylinders to prepare the corresponding standard gas, thereby reducing the gas cylinder cost of the customer.
