Abstract
The utility model relates to a flexible packing bag, in particular to a combined flexible packing bag used to pack the chemical product of chromium salt, such as the industry chromic anhydride, etc. The combined flexible packing bag has multi-layer sheathing structure, and is formed by connecting a layer of polyester fiber cloth material and a layer of polypropylene material. The multi-layer structure of the packing bag can be formed by sheathing the layer of the polyester fiber cloth material and the layer of the polypropylene material, and can be formed into a composite layer by connecting the layer of the polyester fiber cloth material and the layer of the polypropylene material. The multi-layer structure of the packing bag can be formed by the layer of the plastics film clamped between the layer of the polyester fiber cloth material and the layer of the polypropylene material. The combined flexible packing bag has the characteristics of high temperature resistance, corrosion resistance, long service life, simple operation and direct pouring with high temperature.
Description
Under the field: the utility model belongs to a kind of soft packaging bag, particularly about a kind of compound type soft packaging bag of adorning chromic salts chemical products such as industrial chromic anhybride.
Background technology: many dangerous materials are arranged in the chemical products, require comprising that bag and material have higher regulation, traditional mode is to adopt metallic material, and existing problem is price height, cost of transportation height, and loading and unloading are inconvenient.Pack cost with iron to reach per ton be 800 yuans as sodium dichromate (potassium), chromic anhydride (chromic anhybride) are former.The problem that flexible packaging bag in the past exists is that resistance to elevated temperatures is poor, is the condition of high temperature when chemical products go out finished product, can not directly pack, and need be hinged with metal bucket, pours the soft packaging bag packing after the placement cooling again into; Many like this one packaging processes have been wasted manpower and materials, and expense is increased, and produce dust from flying in the bucket process, toxic dust infringement health, contaminated environment.Antiseptic property is poor in addition, and when packaging bag ran into strong acid, highly basic, packaging bag very easily was corroded, and causes chemical industry to produce mouth and exposes, and brings a lot of inconvenience for production, transportation, storage and use, causes a large amount of economic losses and environmental pollution.It is " 96235954 " that Chinese patent discloses the patent No., patent name is the patented technology of " rubber and plastic chemical industry soft packaging bag ", and its adopts single bag structure, high temperature resistant have only 70 more spend, and chromic anhybride finished product temperature is about 110 degree, and the problem of its existence is just as described above.
Summary of the invention: the purpose of this utility model is a kind of high temperature resistant more than 120 ℃, good, the long service life of strong acid-base resistance corrosion beharvior, directly the compound type soft packaging bag of high-temperature filling of design.
The purpose of this utility model is achieved in that a kind of compound type soft packaging bag of design, and it is characterized in that: described packaging bag is the multilayer socket join structure, and it is linked together by the poly-ester fibres cloth material layer and the polypropylene material bed of material and constitutes.
Described packaging bag can be the poly-ester fibres cloth material layer and the polypropylene material bed of material formation that connects together; It also can be the poly-ester fibres cloth material layer and the polypropylene material bed of material formation composite bed that bonds together.
The multiple-structure of described packaging bag can be to accompany plastic film layers between the poly-ester fibres cloth material layer and the polypropylene material bed of material to constitute.
Because the utility model adopts multiple-structure, it is linked together by the poly-ester fibres cloth material layer and the polypropylene material bed of material and constitutes; As formation composite bed that poly-ester fibres cloth material layer and the polypropylene material bed of material are connected together or bond together.Therefore no matter also can be to accompany plastic film layers between the poly-ester fibres cloth material layer and the polypropylene material bed of material, be 120 ℃ of high temperature or low temperature, no matter be to run into strong acid or highly basic can both be used safely, and long service life, cost is low, and is free from environmental pollution.
Below in conjunction with the embodiment accompanying drawing the utility model is described further:
Accompanying drawing 1 is embodiment 1 structural representation.
Accompanying drawing 2 is embodiment 2 structural representations.
Among the figure: 1, skin; 2, middle level; 3, internal layer.
Compound type soft packaging bag among the embodiment, the long 830-850mm that is chosen in of outer bag, the wide 530-540mm that is chosen in; Inner bag is wide less than outer bag size 10mm; Middle the bag long 1050-1100mm of being chosen in, the wide 570-600mm of being chosen in, thickness can be chosen in 0.05-0.08mm, can adorn 50 kilograms for every bag.
Adopt compound type soft packaging bag of the present utility model, make the chromic anhybride Packing Fee by reducing to below 160 yuan/ton for 740 yuan/ton with metal bucket.
Sodium dichromate (potassium) packing charge is by reducing to below 134 yuan/ton for 740 yuan/ton with metal bucket.Total volume of railway freight improves 40%.The storage floor area is saved 1/3-1/2.
This product is not found an example because the bag that temperature or corrosion cause damages in the directly cans and soak and reach the test in 6 years repeatedly of 120 ℃ of high temperature in chromic anhybride liquid.
