Description
Technical field
The present invention relates to drainage screen technical field, particularly relate to a kind of micro-calcium anion multifunctional drainage screen and its preparation
Method.
Background technology
Indoor environment has important impact to the health of people, and according to statistics, people constituted about one day time indoors whole
It 80%-90%, and the old,weak,sick and disabled person and anemia of pregnant woman, the infant activity time indoors is then longer.And the sickness rate of crowd
There is significant positive correlation with mortality rate and Atmospheric particulates mass concentration, even and if this positive correlation is less than related state
Family's air quality control regulations, also still exist.Therefore people increasingly pay close attention to IAQ (indoor air quality).
Raising with people's living standard and the quickening of urbanization process, the use of all kinds of air conditioning systems is more and more general
Time.And the main purpose of air conditioning system is to create health, a comfortable environment for indoor occupant.But many air-conditionings at present
System design does not account for the particulate matter deposition in air-flow, and contaminated air conditioner ventilating system can affect indoor inhalable particles
Thing concentration and microorganism concn.And door and window is closed by people in order to economize on electricity, thus causing the particulate matter in indoor air flow dense
Degree increases.Therefore air-purifying net has been widely recognized as by people and has applied in recent years, filtration system mainly adopt non-woven fabrics or
INVENTIONPaper filter granule dust, activated carbon adsorption noxious odor isotype.
The defect of air-conditioning filter net is mainly on the market at present：(1) organizine of the partial amt and tram not shape in braiding
Become to intersect, short texture；(2) organizine and tram do not bond in point of intersection, are easily shifted over, and cause filter efficiency not
Fixed, air drag is uneven；(3) Use Limitation is short, ability.
Content of the invention
The present invention proposes a kind of micro-calcium anion multifunctional drainage screen and preparation method thereof, solves current air conditioning filter
The inefficient problem of net filtration.
The technical scheme is that and be achieved in that：A kind of micro-calcium anion multifunctional drainage screen, from top to bottom according to
