Abstract

L'invention concerne un matériau barrière aux matières particulaires et son application dans la protection contre la brume sèche, se rapportant au domaine des masques de protection respiratoire. Le matériau barrière aux matières particulaires comprend un polymère cationique, le polymère cationique représentant de 0,1 à 10 % en pourcentage en masse du matériau barrière aux matières particulaires. Le matériau barrière aux matières particulaires comprend des charges électriques permettant de former une couche de protection microélectronique. Des matières particulaires et une substance macromoléculaire ayant des charges similaires se repoussent pour empêcher le passage des matières particulaires. Les matières particulaires et une substance macromoléculaire ayant des charges différentes s'attirent pour se condenser en des matières particulaires de grande taille pour se déposer et chuter de sorte que les matières particulaires ne soient pas absorbées par le corps humain. Le matériau barrière aux matières particulaires peut améliorer l'effet de filtrage d'un matériau de protection contre la brume sèche et d'un dispositif de protection contre la brume sèche, ce qui permet d'améliorer l'effet de protection contre la brume sèche. De plus, le matériau barrière aux matières particulaires peut également être directement pulvérisé sur les surfaces de positions où la brume sèche doit être entravée, tel que le visage ou des dispositifs de protection contre la brume sèche, ce qui permet de protéger efficacement de la brume sèche.
