Abstract

The invention discloses a nuclear track membrane screen, a nuclear track membrane screen window and a preparation method of the nuclear track membrane screen, wherein the nuclear track membrane screen comprises a nuclear track membrane layer, an extension layer for increasing the superficial area of the nuclear track membrane layer, and a supporting layer for supporting the nuclear track membrane layer and the extension layer, wherein the nuclear track membrane layer, the extension layer and the supporting layer are sequentially overlapped. According to the invention, the nuclear track membrane layer, the extension layer and the supporting layer are combined together to obtain the wide nuclear track membrane screen having the advantages of high mechanical strength, long service life and good air filtering effect. The area of the nuclear track membrane screen can be specifically chosen according to the practical requirement. The nuclear track membrane screen can prevent outdoor atmospheric pollutants from entering indoors and meanwhile allows indoor pollutants to flow outdoors during air exchange, so that the concentrations of indoor pollutants are greatly reduced. The nuclear track membrane screen is convenient to use and transport; the industrial application is convenient.

Description

technical field [0001] The invention relates to the field of air filtration, in particular to a nuclear pore veil, a nuclear pore screen window and a preparation method of the nuclear pore veil. Background technique [0002] Air is closely related to the survival of human beings, and it directly participates in processes such as gas metabolism, material metabolism and temperature regulation of the human body. A person breathes more than 10,000 liters of air every day, and the equivalent mass is about 12.9kg, which is about 10 times the amount of food and drinking water needed every day. Clean air is one of the necessary conditions for human survival. A person who does not eat for five weeks or drinks water for five days can still maintain life, but if he does not breathe air for more than 5 minutes, he will die. [0003] However, with the rapid development of modern industry and transportation, the emission of soot and automobile exhaust exceeds the self-purification limit ...
