Problems solved by technology

However, the use of powder as an adsorbent also has its disadvantages. For example, the adsorption capacity of the powder wrap is relatively low, and the adsorption ratio (that is, the ratio of the weight of the adsorbent to absorb and saturate the liquid to the original weight of the adsorbent) is only about 1.5; more importantly Unfortunately, powders often seep or leak from the small holes of the wrapping materials that cover them, especially when they are flapped or moved, causing secondary powder pollution, which is unacceptable for aerospace fields that require high site cleanliness of
Reducing the pore size of the wrap can reduce the leakage of decontaminant powder, but it will affect the penetration of UDMH

Embodiment 1

[0032] refer to figure 1 , in this embodiment, the decontamination film 2 is used to completely wrap the detergent powder 1 to form a decontamination agent packaging bag, a plurality of detergent packaging bags are wrapped with a diffusion layer 3, and the outer coating layer 4 is wrapped, and The seam is tied with sewing thread to form a decontamination unit. The product formed in this example is fully soaked in unsymmetrical dimethyl hydrazine, taken out and drained, and the adsorption ratio can be measured to be between 4.5 and 5.5.

Embodiment 2

[0034] refer to figure 2 , in this embodiment, the decontamination film 2 is used to completely wrap the detergent powder 1 to form a decontamination agent packaging bag, a plurality of detergent packaging bags are completely wrapped with a diffusion layer 3, and the outer coating layer 4 is wrapped again, It is tied with sewing thread to form a decontamination unit.

Embodiment 3

[0036] refer to image 3 , In this embodiment, a plurality of decontamination units with the structure shown in Embodiment 1 are expanded in one-dimensional direction to form the form of decontamination cords. The product formed in this example is fully soaked in unsymmetrical dimethyl hydrazine, taken out and drained, and the adsorption ratio can be measured to be between 4.5 and 5.3.

Abstract

The present invention involves a partial two -tadpole washing set, which includes several cleaning units. Each washing unit includes the following components: at least one washing agent packaging bag.2) Washing disinfection powder (1); the spread layer of at least one washing of the packaging bag (3) described at least one washing of the packaging bag;Several cleaning units are repeatedly arranged in one -dimensional, two -dimensional or three -dimensional direction, forming a cleaning cable, cleaning and dispelting, or washing the pillow.The partial melon of the present invention can prevent the abolition of the powder and improve the washing and dispellation capacity of the washing agent, and it is convenient to make the form of industrial spare parts such as washing, discharge, or washing the pillow.It is convenient to use and is convenient to remove without polluting the scene.

Description

technical field [0001] The invention relates to the field of liquid chemical raw material leakage treatment, in particular to a decontamination kit for unsymmetrical dimethyl hydrazine. Background technique [0002] UDMA is a widely used rocket propellant, which is flammable, explosive and highly toxic. In the process of using this fuel, leakage accidents are prone to occur. If the leakage is not handled effectively, properly and quickly, it is easy to cause secondary hazards such as fire, explosion, environmental pollution, and personnel poisoning. Therefore, it is necessary to use this material frequently. All units and sites are equipped with leakage emergency treatment equipment to reduce or eliminate secondary hazards caused by leakage and ensure the safety of personnel, the environment and property. The operation of cleaning up and eliminating toxic and hazardous substances in spilled liquids is called "decontamination". [0003] UDMH is a volatile organic compound l...
