Abstract
The utility model relates to a carbon dioxide steel cylinder for food with a small caliber, which is provided with a seamless steel bottle body and a bottle mouth which shrinks through the application of pressure and is provided internal threads. The utility model is characterized in that a phosphate layer and a food stage epoxy phenolic resin layer are arranged in sequence on the inner wall of the steel bottle body. A full polyester power layer is arranged on the outer wall of the steel bottle body. The utility model can effectively prevent iron rust and pollution to carbon dioxide in the bottle by toxic materials which is contained in common paint to lead the carbon dioxide steel cylinder for food with a small caliber to conform to the specifications of the standard of food sanitation.
Description
The utility model is the container about gas storage, particularly about the food carbon dioxide steel cylinder.
The progress of the development of world economy and science and technology makes people's living and diet that huge variation also take place.With the quickening of people's rhythm of life, the finished product trend that beverage is canned and bottled is made progress day by day.And the beverage of carbon dioxide containing gas is also widely popular.Be to make this class beverage with sodium bicarbonate (sodium bicarbonate) at first, as carbonated drink, cola etc., development is afterwards directly injected beverage with carbon dioxide.Do not conform with the steel cylinder that is used to store compression arbon dioxide that food hygiene requires but have as yet up till now, be used to store the food of producing by special industrial gasses originating firm and use for beverage production manufacturer with carbon dioxide.So generally still use sodium bicarbonate, or directly produce carbon dioxide by canned factory oneself.But the latter needs a cover specialized equipment, increases productive costs.
The purpose of this utility model is to provide a kind of small-bore food carbon dioxide steel cylinder, it can prevent effectively that steel cylinder from getting rusty or other toxic substance pollutes carbon dioxide, make it meet the food hygiene requirement, thereby can be extensive use of carbon dioxide, reduce production costs by professional gas plant produced.
The purpose of this utility model is achieved in that a kind of small-bore food carbon dioxide steel cylinder, it has seamless steel body and shrinks and be provided with the bottleneck of negative thread through spinning, and it is characterized in that: described steel body inwall is disposed with phosphate coating and food stage epoxy phenolics layer.
The utility model is owing to apply the food stage epoxy phenolics layer that meets the food hygiene requirement in the steel body, therefore the carbon dioxide of storing in the bottle is in contact with it and not polluted by objectionable impurities.And between steel body and food stage epoxy resin layer, be provided with the phosphate coating that contains zinc salt, manganese salt or zinc-manganese salt that generates through bonderization.The water insoluble corrosion that can prevent the steel body effectively of this phosphate coating, its porosity has strengthened the reliability that food stage epoxy phenolics layer adheres to again simultaneously.And above-mentioned food stage epoxy phenolics layer does not contain poisonous, the objectionable impurities of solubility, guarantees to store in a carbon dioxide in the bottle and is in contact with it and not polluted by objectionable impurities, makes it conform with the food hygienic standard standard.Secondly steel body appearance also is provided with toner coating or other decorative paint, and itself and aqueous vapor are isolated, and prevents to get rusty, and stops the carbon dioxide secondary pollution to storing in the bottle.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
Small-bore food comprises seamless steel body 3 and bottleneck 6 with carbon dioxide steel cylinder 1.Bottleneck 6 is that above-mentioned steel body 3 front ends utilize hot spinning to shrink to form, with keep its seamless can high voltage bearing characteristic.Bottleneck 6 is provided with screw thread, in order to connect different food machinerys.Steel body 3 inwalls set gradually phosphate coating 4 and food stage epoxy phenolics layer 5.Phosphate coating 4 gets for handling with the phosphatization liquid (powder) that contains zinc salt, manganese salt or zinc-manganese salt, and its thickness is not less than 0.5 micron.Above-mentioned phosphate coating 4 strong adhesions cover on the inwall of steel body 3 reliably, form that one deck crystallization is careful, even compact, the anticorrosive film of good flexible high-quality.Food stage epoxy phenolics layer 5 is topped on above-mentioned phosphate coating 4.Above-mentioned food stage epoxy phenolics layer 5 can be used the IP2004-822 coating of U.S. PPG company, or the 214-3 coating of PPG Suzhou company, or other epoxy phenolic resin paint that meets food hygienic standard applies and gets; It is combined closely with above-mentioned phosphate coating 4 in bottle, formed the protective layer of complete, bright and clean a, non-corroding, free from admixture, free from extraneous odour, guarantee that the food grade compression arbon dioxide that is in contact with it in the bottle is not contaminated, meet food hygienic standard (for example U.S. US FDA175.300 health standards).Above-mentioned phosphate coating 4 and food stage epoxy phenolics layer 5 also extend the interior threaded surface that is covered in bottleneck 6.Appearance at steel body 3 is coated with coating 2.This coating 2 can have the strong toner of weather resisting property or other decorative paint to constitute, and it can weatherproof in long-term use, protects the outside face non-corrosive of steel body reliably, thereby prevents the possibility of the carbon dioxide secondary pollution in the bottle.
