Problems solved by technology
Can our power plants, steel plants, cement plants, chemical plants, and automobile factories all be shut down? Of course not, so what about air pollution and smog? Purification measures must be taken, because air pollution and smog have seriously threatened our health, so the research project of large-scale outdoor air purification equipment is of great significance, but the key components in the existing large-scale outdoor air purification equipment are composite integrated filter filtration The effect is not ideal, so there is an urgent need for a new technical solution to solve this problem in the existing technology

Embodiment Construction
[0022] The present invention proposes a production process of electrostatic fiber hot-rolled non-woven fabric filter medium, please refer to Figure 1, the production process specifically includes the following steps, and the following steps are carried out in sequence,
[0023] Step 1. Fiber unpacking and mixing
[0024] The raw material is polypropylene short fiber with no odor and attached with static electricity. The fiber is roughly opened by the coarse gear roller of the opener, and the coarsely opened fiber is finely opened by the fine tooth roller to obtain loose fiber with reduced electrostatic field. ; Loose fiber enters the large warehouse blender through the conveying pipeline for fiber mixing;
[0025] Step two, combing
[0026] The fibers fully mixed by the Dacang cotton blender in the step 1 are transported to the air pressure quantitative feeding machine by air flow, and the mixed fibers are transported to the carding machine by pressure. During the carding pro...

Abstract
The invention provides a production process of an electrostatic fiber hot-rolled non-woven fabric filtering medium and belongs to the technical field of novel industrial material preparation. The method specifically includes the following steps of 1, fiber unpacking mixing; 2, combing; 3, hot rolling; 4, scrap edge winding and packaging. Compared with the prior art, the production process can manufacture the filtering medium with static without an electret, smell-free polypropylene short fibers are adopted as raw materials, electrostatic is attached to the polypropylene short fibers, and the electrostatic fiber hot-rolled non-woven fabric filtering medium is processed through a hot-rolling method non-woven fabric production process. The purification effect of a filter element manufactured from the electrostatic fiber hot-rolled non-woven fabric filtering medium is better, the electrostatic field is strong, the electrostatic durability is good, and the cost is low. The electrostatic fiber hot-rolled non-woven fabric filtering medium can be applied to the air filter element and can also be applied to a liquid filter element. Social benefits and economic benefits are very remarkable, and a huge contribution is made for purifying air and effectively and scientifically treating air haze.
Description
technical field [0001] The invention belongs to the technical field of preparation of new industrial materials, and in particular relates to a production process of electrostatic fiber hot-rolled non-woven fabric filter medium. Background technique [0002] With the gradual improvement of people's living standards, people's requirements for the quality of life are getting higher and higher, and the awareness of environmental protection is gradually increasing. [0003] The purpose of air purification is to effectively control smog so that people can live in a comfortable air environment. Industrial modernization should be said to be the root cause of air pollution. my country's annual output of cement ranks first in the world, and crushing and roasting of ore will inevitably produce a large amount of dust. Iron and steel plants, chemical plants, power plants, etc. will all produce varying degrees of environmental pollution to the air. However, we cannot shut down all thes...
