Problems solved by technology

[0004] The purpose of the present invention is to provide a protective mask film processing technology to solve the problem that the PET film produced by the existing PET film preparation process proposed in the above-mentioned background technology has the effect of anti-spray, but because the PET film needs to be worn on the face Front, so the gas formed when the user breathes will form mist on the surface of the PET film, and the mist will hinder the line of sight and affect the use of the problem

Abstract

The invention discloses a protective mask film processing technology. The protective mask film processing technology comprises the steps of preparing materials, feeding materials, pre-crystallizing, drying, extruding, filtering, cooling and casting pieces, stretching and forming, and carrying out an anti-fog experiment. Hydrophilic acrylic acid copolymerization resin is directly added into the formula, so that a processed protective mask film has an anti-fog effect; when exhaled hot air is ejected onto the surface of a protective mask film during use, due to the effect of the hydrophilic acrylic acid copolymerization resin, the protective mask film is prevented from being atomized, and the performance of the protective mask film is better; and high-temperature steam ejected by a high-temperature steam ejector is added in the steps of the processing technology, so that the ejected hot steam is ejected onto the protective mask film, whether the film has an anti-fogging function or not isjudged, the protective mask film which can leave a factory after being processed has the anti-fogging function, defective goods are avoided, and the product quality is improved.

Description

technical field [0001] The invention belongs to the related technical field of protective mask film, and in particular relates to a protective mask film processing technology. Background technique [0002] Droplet transmission, that is, airborne droplet transmission, is one mode of airborne transmission. The pathogen is coughed, sneezed, and the secretions and droplets discharged from the conversation by the source of infection, so that the susceptible person is inhaled and infected. Epidemic meningitis, scarlet fever, pertussis, influenza, measles and other diseases are transmitted through this method. Generally, droplet transmission is only possible when close contact with the source of infection is possible, and it is relatively safe to be more than 1 meter away from the source of infection. Because, without the help of external conditions (such as wind), the possibility of spraying droplets beyond two meters is almost impossible. Therefore, when blocking droplets, it i...
