Description

A kind of negative ion diatom ooze interior wall coating
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of negative ion diatom ooze interior wall coating.
Background technology
Universal along with internet and indoor body-building equipment, people produce and mode of life modernization more, more work and sports entertainment all can carry out in indoor, shopping also need not be gone into the street every day, suitable kryptoclimate makes people often need not arrive outdoors, like this, most of activity time of people is all spent in indoor.Add up according to investigations, people every day on average nearly more than 80% time spend in indoor, have even up to more than 93%.Therefore, the relation of IAQ (indoor air quality) and HUMAN HEALTH is just more tight, and people also just pay attention to IAQ (indoor air quality) more.
Negative ion is called " air VITAMIN " by medical circle, and its Main Function shows: negative ion is oxonium ion electronegative in air, can promote human metabolism after entering blood by lung.Medical experiment proves, the health of people and long-livedly depend on pure and fresh and have the air of enough negative ions, negative aeroion all has active effect to the central nervous system of human body, blood circulation, respiratory system, basal metabolism and the immunological competence of human body can be increased, have certain curative effect to asthma, bronchitis, rhinitis, respiratory tract infection.Negative aeroion has splendid purifying and dedusting, reduce second hand smoking harm, prevention respiratory tract disease, improving water flood, anti-oxidant, anti-aging, remove interior free yl, reduce the effect such as blood viscosity, enjoy the laudatory titles such as " tie up him oxygen " " air VITAMIN " " long-lived element " " air vitamin b6 usp " in medical circle.The wall coating of permanent constantly anion releasing in a large number, family room can be become natural ecological environment, reach the air condition that virgin forest, natural waterfall, Gold Coast, green open country etc. emulate naturally, its benefit is self-evident.
