Abstract

The invention provides a functional desk which can control the air pollution in a classroom. The functional desk is characterized in that a layer of facing that has the effect of being antitoxic and bacteriostatic is tiled at the upper face of the desk and an antibiotic convenient box is arranged in the tank of the desk. The technique integrates a plurality of antitoxic and bacteriostatic techniques such as photocatalyst, tourmaline, nano-inorganic silver, activated carbon, etc., to carry out all-directional, short range and detail network type control of the air pollution in the classroom, thereby being high efficient, simple, convenient and practical.

Description

A kind of functional desk capable of controlling air pollution of classroom

Technical field originally

Invention belongs to the room air pollution control technology, particularly discloses a kind of functional desk capable of controlling air pollution of classroom.

Background technology

Room air pollution is the second largest pollution sources that are only second to auto-pollution, and according to statistics, the whole world has nearly half people to be in the room air pollution, and especially students learn in the classroom all day, and personnel are intensive, are the air-polluting acute sufferers.

Here the pernicious gases such as the radon that discharges except construction material, formaldehyde, benzene, ammonia, carbon dioxide, smell, steam and pathogen that physical activity and metabolism bring become the important pollution sources of room air.According to expert statistics, only people's lung is just discharged 25 kinds of poisonous substances, and the pollutant that these poisonous substances and skin, sweat gland are discharged is repeated to absorb, and will produce illeffects, even cause cross-infection, the physical and mental health of crisis youngsters and children.In recent years, though indoor freshener emerges in an endless stream, mostly at the family room design, the intensive classroom of incompatibility personnel uses.Strictness says that the air pollution control of classroom has become the dead angle, and control technology and the product of developing air pollution of classroom are imperative.

Summary of the invention

In order to address the above problem and the prior art deficiency, invented a kind of functional desk capable of controlling air pollution of classroom.This desk is integrated antitoxin antibacterial multiple complex techniques such as current advanced person's photocatalyst, tourmaline, nano inorganic silver and active carbon.On the basis of not changing the former desk structure of student, add antitoxin antibacterial table flush coat and the antitoxin antibacterial box that makes things convenient for, realize many technology, comprehensive, closely, the control of close net formula.

Concrete grammar is:

One, makes antitoxin antibacterial desk flush coat.

1, selects anti-biotic material for use.Select the titanium dioxide of 2% 20-30 nanometer and inorganic silver, nano level tourmaline pulvis respectively for use.

2, activation modification.Above-mentioned material is added flowable, lubricant and dispersant, put into mixer and stir and to make it to be evenly distributed and form the good binding interface.

3, make composite resin particle.Anti-biotic material after the modification is rendered to base-material PA ₆In and add flexibilizer, i.e. elastomer.Stirring is heated and is made PA through the screw rod extruder ₆Composite resin particle.

4, thermoplastic shaping is with PA ₆Composite resin particle is put into the thermoplastic shaping machine, makes 600 * 400 * 5mm thin plate, be put on the desk platform nylon sheet is smooth, and promptly be desired antitoxin antibacterial desk flush coat.Use 3-5 to change once.

Two, make the antitoxin antibacterial box that makes things convenient for, at first make the plastic casing of a four sides with many apertures, the specification of box is high 150mm, long 300mm, wide 100mm; Then, put into granular active carbon, the particle of active carbon is greater than the aperture at box four sides, will make things convenient for box to lean on a side to be placed in the desk hall during use, and per semester integral replacing once.

The advantage of this product is:

One, adopts the compound antitoxin antibacterial technology of compound, realized many means, control by all kinds of means.

1, photocatalyst catalytic action, because the desk flush coat has added nano titanium oxide, under solar radiation, catalytic reaction takes place, produce free hydroxy and active oxygen and carry out photoredox reaction, can the chemical combination decomposing formaldehyde etc. various organic pollutions, organic pollution is resolved into innocuous substance water and carbon dioxide.

2, tourmaline anion effect because tourmaline has the piezo-electric effect of natural uniqueness, can emitting far-infraredly can be improved microcirculation in human body, discharges a large amount of anions and makes active oxygen, promotes human body metabolism.The tourmaline self generating can continue to discharge negative aeroion, dispels pernicious gases such as formaldehyde, benzene, ammonia.

3, nano inorganic silver bactericidal action.Nano inorganic silver can kill 650 various bacteria at per minute, has broad-spectrum bactericidal action, does not produce any drug resistance, makes desk become antitoxin antibacterial platform.

4, the suction-operated of active carbon.Active carbon has extremely strong adsorptivity, every gram specific surface that active carbon has is equivalent to 1000 square metres, can owing to adopt compound composite antibiosis technology to overcome the shortcoming of monotechnics, improve the air pollution control effect greatly in the poisonous and harmful substance in the transient absorption surrounding air.

Two, desk is the main region and the articles for use of student's activities, each student will face desk, use desk, close at hand, and in the classroom, evenly put, the use of functional desk capable just realized to air-polluting closely, comprehensive, close net formula control, its control effect is that any freshener all is beyond one's reach.

Three, because functional desk capable is a layer overlay flush coat again on former desk basis, place the antibiotic box that makes things convenient in the table hall, neither needing to make does not again need to change former table structure yet, and operation is succinct, and easy to use, expense is low, is convenient to use and promote.

Four, owing to photocatalyst, tourmaline only play instrumentality, chemical reaction does not take place in itself, and the inorganic silver long acting antibiotic, it is strong that nylon 6 has super toughness, anti-folding, bending resistance, impact resistance,, acid-fast alkali-proof, so this product can use for a long time, greatly reduce use cost.

The specific embodiment

Following three steps of main branch are carried out:

One, makes the functional desk capable flush coat

1, selects anti-biotic material for use, nano titanium oxide, tourmaline, nano inorganic silver;

2, modification, interpolation flowable, lubricant, dispersant stir;

3, make composite resin particle, the modification anti-biotic material is dropped into base-material nylon 6, and add flexibilizer;

4, thermoplastic shaping;

5, keep flat on the desk desktop.

Two, make the antibiotic box that makes things convenient for

1, makes four sides plastic casing with holes earlier

2, throw in granular active carbon

3, be placed in the desk hall

Three, antitoxin antibacterial flush coat 3-5 changes once, antibioticly makes things convenient for box semester integral replacing once.

Claims

1. a functional desk capable of controlling air pollution of classroom is characterized in that on the basis that does not change former desk structure, and layer overlay has the desk flush coat of multiple compound antitoxin antibacterial technology and place the antitoxin antibacterial box that makes things convenient in the table hall on the table.
