Problems solved by technology

[0008] However, in the traditional ammonia filling process, the solid ammonia storage material reacts violently with ammonia gas to form a solid ammonium strontium chloride with higher hardness, and the ammonium strontium chloride solid formed by the preferential reaction at the tank inlet will Prevent the unreacted solid ammonia storage material from contacting with ammonia gas to react, thus hindering the uniform and rapid filling of the whole ammonia tank

Abstract

The invention relates to a preparation method of modified glass fiber cloth. The method comprises the following steps of placing glass fiber base cloth in a suspension liquid for dipping and pulling, and then carrying out heat treatment, wherein the suspension liquid is prepared from the following components in parts by mass of 0.3 to 1 part of graphite, 0.1 to 0.2 part of carbon black, 0.1 to 0.5 part of inorganic micro powder, 0.5 to 2 parts of organic resin, 1 to 3 parts of alcohol and 2 to 4 parts of water; the inorganic micro powder is selected from at least one of aluminum oxide micro powder and magnesium oxide micro powder; and the organic resin is phenolic resin. The modified glass fiber cloth prepared by the preparation method has better heat-conducting property.

Description

technical field [0001] The invention relates to the field of tail gas treatment, in particular to a modified glass fiber cloth and a preparation method thereof, a solid ammonia storage device and an automobile. Background technique [0002] Selective catalytic reduction technology (SCR) is a treatment process for NOx in diesel vehicle exhaust emissions, that is, under the action of a catalyst, the reducing agent ammonia or urea is injected to reduce the NOx in the exhaust gas to N 2 and H 2 O, its reaction equation is as follows: [0003] NO+NO 2 +2NH 3 →2N 2 +3H 2 O; [0004] 4NO+O 2 +4NH 3 →4N 2 +6H 2 O; [0005] 2NO 2 +O 2 +4NH 3 →3N 2 +6H 2 O. [0006] SCR technology is widely used in after-treatment of diesel engine exhaust. By optimizing the fuel injection and combustion process, the generation of particulate PM in the engine can be controlled; while the nitrogen oxides formed under the condition of rich oxygen outside the engine can be used in time wi...
