Description
Technical field
The present invention relates to haydite, and in particular to a kind of gravel has the magnesite light ceramic of air purification function.
Background technology
The air purifying preparation that supplies in the market has following several types：Absorbent-type air purifying preparation, covering type taste removal
Product and Breakdown type taste removal product.Absorbent-type air purifying preparation be using materials such as activated carbon, bamboo charcoal, molecular sieve, mineral
The performance such as physical absorption, chemisorbed, catalysis oxidation and reduction removes the purification product of pollutant；Covering type taste removal product is profit
The various abnormal flavour of in the air are covered with the fragrance of aromatic hydrocarbon, abnormal flavour is not in fact removed by a lot of air fresheners, simply
With a kind of odor type, abnormal flavour is covered；Breakdown type air clearing product is more rare on the market.
Chinese patent Authorization Notice No.：103861421 B of CN, authorized announcement date：On November 18th, 2015, entitled " one
Kind of air purifying preparation ", discloses that " a kind of air purifying preparation, its preparing raw material is contained by mass fraction：Diatomite in powder, zeolite powder,
Medical stone powder, tourmaline powder, activated carbon powder, sepiolite powder, titanium dioxide powder, and adopt and prepare with the following method：1) by kieselguhr
Powder, zeolite powder, medical stone powder, tourmaline powder, activated carbon powder, sepiolite powder, titanium dioxide powder mixing；2) by step 1) gained mix
Compound pelletize；3) baking step 2) gained mixture after pelletize.Air purifying preparation specific surface obtained in the present invention is big and uniform,
Good to the adsorption-decomposition function effect of in the air harmful substance, be for interior, the depollution of environment of the closing space such as in-car and various skies
The ideal chose material of gas purifier ".
The weak point of above-mentioned patent is：(1) diatomite in powder, zeolite powder, medical stone powder, tourmaline powder, activated carbon powder and sea
Afrodite powder is not through necessary modification, it is difficult to really play the effect of its effective purify air.(2) gained mixed powder
Granulating disc pelletize is adopted after the clear water stirring for adding 20-30%, be a kind of circular granular of a diameter of 1.2-1.6mm.Should
Itself normal moisture content of the mixed powder of invention is more than 10%, and the circular granular moisture content after the pelletize that adds water will be greater than 30%, and
Drying temperature less than in the case of 100 DEG C, it is difficult to circular granular be dried in 3 hours.Kieselguhr, zeolite, Maifanitum,
After tourmaline and meerschaum carry out heat treatment process at 250～450 DEG C, its absorption property is relatively good, and this is the technology of this area
Personnel know altogether；The circular granular of the invention is dried in the case of less than 100 DEG C, can not effectively improve the work of purify air
With, and the comprcssive strength of circular granular also very little, gently one pinched with handss, circular granular will be crumbed as powdered.
Spheroidal air purifying preparation, molecular sieve, desiccant or the other spherical granules that supplies on market, in pelletize
It is first powdery dispensing to be processed into a kind of bead of diameter less than 0.5 millimeter, then by the vaporific aqueous solution for preparing, spray in journey
Spill in the bead in comminutor in operation, then powdery dispensing is trickled down the surface of the bead in moistening, through being repeated several times
The vaporific aqueous solution of sprinkling and powdery dispensing is trickled down the surface of the bead in moistening, through the parcel of layer upon layer, bead
Volume constantly increase, be finally completed the overall process of pelletize, be prepared into a kind of spherical granules, due to spherical granules internal junction
Structure is very closely knit, greatly reduces the effective specific surface area of spherical granules, the proportion of spherical granules and bulk density all than
Larger, directly influence the absorption purifying effect of spherical granules.
