Zeolite coated nasal mask and disposable particulate respirator filtration media

摘要

A method and use of Zeolite coated nasal mask and disposable particulate respirator filtration media that will absorb air pollutants such as NOx, Ozone, PM2.5 and radioisotopes of cesium, strontium and polonium (the progeny of radon gas) and protect the wearer from inhalation of said deleterious agents.

1. A method for producing HEPA mechanical air filtration media, nasal mask and disposable particulate respirator filtration media comprising i) zeolites which act as a radiation, radioactive isotope and air pollution trapping agents, ii) retention aid and iii) a sealant polymer, the method comprising the steps of:
a) mixing the zeolites at a ratio of 60-80% with 40-20% of boehmite as the retention aid in deionized water with a ratio of water to solids of 5:1, the water has a pH of 8-9 and a temperature of 28-30 degrees C., the sealant polymer is added to the mixture in which the sealant polymer consists of a 60:40 hydroxypropylcellulose (HPC) to ethoxylated methyl glucoside (EMG), for two minutes; b) applying the aqueous mixture from step a) onto a woven or nonwoven polypropylene fabric to form a bottom layer of 1.8 mil thickness; c) applying the aqueous mixture from step a) on the coated polypropylene fabric to form a top layer of 1.4 mil thickness which permanently seals the fabric.
