Problems solved by technology

However, the current anti-smog screens lack adjustable performance, and are only a single anti-smog, which has many disadvantages
For example, when the smog index is not high, you can block the smog with a large aperture. If you use high-performance yarns such as hepa, the windows will not be well lit.
And once the screen window is polluted, it is not easy to clean. When the screen window is removed, the entire window has to be closed again, which cannot be ventilated.

Abstract

The invention discloses high-efficiency low-impedance haze-resistant ventilation window gauze and a preparation method thereof. The method comprises the following steps of firstly preparing a PTFE (poly tetra fluoro ethylene) microporous membrane material and additive master batches, then preparing a PTFE-PP (propene polymer) composite material, and finally preparing a deep-layer static electricity electret PTFE-PP filter material under the corona action of a high-pressure static electricity transmitting device so as to obtain the high-efficiency low-impedance haze-resistant ventilation windowgauze. According to the high-efficiency low-impedance haze-resistant ventilation window gauze, the cleanliness is 99-99.9%, the molecular weight is 2.5-3 millions, the processing technology is simple, the cost is low, the processed haze-resistant ventilation window gauze has a simple structure, can be used for effectively stopping haze from interchanging with air during use, and can further be used for effectively settling local dust particles indoors, thereby achieving the purpose of purifying indoor air.

Description

technical field [0001] The invention relates to the technical field of air filtration, in particular to a high-efficiency, low-resistance anti-haze breathable window screen and a preparation method thereof. Background technique [0002] In recent years, with the development of production industrialization, air pollution and environmental pollution have become more and more serious, directly affecting human daily life and health. The survey results show that the number of days with smog weather in major cities in my country is more than half. The so-called smog refers to the total amount of nitrogen oxides and particulate matter in the air exceeding the standard, resulting in low visibility. The main components in the air during haze weather include particles such as tiny particles, sulfuric acid, nitric acid, and organic hydrocarbons. These substances cause atmospheric turbidity, blurred vision and deterioration of visibility. If the horizontal visibility is less than 10,0...
