Production technology of net-shaped filter material for waste gas filtration

Abstract

The invention discloses a production technology of a net-shaped filter material for waste gas filtration. The production technology comprises the material ratio and the production technology processes. According to the material ratio, materials including 67%-81.5% of PP-S2040, 3%-6% of anti-ultraviolet agent, 10%-15% of flame retardant, 1%-3% of flexibilizer, 3%-5% of PP color master batch, 1%-3% of crystallizing agent and 1-3% of activated carbon are included. The production technology processes include that 1), the PP-S2040, the anti-ultraviolet agent, the flame retardant, the flexibilizer, the PP color master batch, the crystallizing agent, the activated carbon and other materials are put into respective bins; 2), metering is conducted according to the ratio; 3), the materials are mixed and stirred for 5 minutes; 4), the mixed raw materials are dried; 5), the raw materials are heated; 6), a mold is closed; 7), the hot-melted raw materials are ejected out; 8), the mold is cooled; 9), the mold is opened; 10), a net-shaped filter material is ejected out; 11), the net-shaped filter material is taken out; 12), the net-shaped filter material is inspected; 13), the net-shaped filter material is packaged; and 14), the net-shaped filter material is warehoused.

Description

technical field [0001] The invention relates to a production process of a mesh filter material for exhaust gas filtration, belonging to the technical field of organic material injection molding and waste gas treatment environmental protection, and in particular to a process for producing a mesh filter three-dimensional filter material by using several materials. process method. Background technique [0002] The manure and cleaning water of livestock and poultry will produce a lot of odorous gas. In order to freshen the air in the livestock and poultry house, the exhaust gas of the livestock and poultry house needs to be exhausted to the outside with a strong exhaust fan. There are many kinds of exhaust gas in the livestock and poultry house, mainly including ammonia. gas, hydrogen sulfide, volatile fatty acids, skatole, alcohols, etc.; among these waste gas substances, ammonia (NH) has the greatest impact on humans and livestock. 3 ) and hydrogen sulfide (H 2 S), ammonia a...

Problems solved by technology

However, neither the traditional organic materials nor the injection molding process can meet the requirements of the mesh structure filter profile, because the traditional organic materials cannot meet the performance requirements, and a new material mix ratio must be developed. In addition, the injection molding injection point of the traditional process is generally However, there are dozens of injection molding points for this net-like structure filter material, and they must be synchronized, equal in amount, and positioned accurately; therefore, the applicant proposes a production of a net-like filter material for exhaust gas filtration.
