Abstract
The invention is a fabrication process for a meerschaum air purifying agent. According to the invention, purified meerschaum with a purity no less than 80% produced by Hunan Hongyan Meerschaum Technology Ltd. is used as a raw material; a finished product is prepared by carrying out a reaction in a hydrochloric acid solution at specific temperature under the conditions of pressurization and stirring, carrying out automatic extraction and reverse osmosis with a membrane machine and repeated rinsing and filtration until the pH value of a resultant is about 6, dehydrating the resultant with a plunger pump and a filter press so as to obtain a filter cake, drying the filter cake with a flash evaporation drier to obtain powder, allowing the filter cake to enter into a chain pulverizer and an extruder for processing so as to obtain master batch, adding powder into the master batch, putting an obtained mixture in a rotary pelleting machine for water spraying and granulation and drying obtained granules in an adjustable rotary drier to obtain the meerschaum air purifying agent. The fabrication process guarantees hole capacity of meerschaum; the prepared meerschaum air purifying agent which is an adsorptive purifying material used for treating environmental pollution has greater capability of adsorping formaldehyde than other charcoal products do under a same condition, having a removal rate no less than 86%.
Description
Technical field
The present invention relates to a kind of sepiolite air purifying preparation manufacture craft.
Background technology
Present indoor environment; The air pollution of PE is more serious; Particularly one of primary pollution source that indoor decorating brought " formaldehyde " is confirmed as one type of carcinogenic substance by the World Health Organization; And in the market to indoor environment; Especially the formaldehyde pollution aspect purified product of administering is very different in the PE air pollution; Parameter is different; Carry out the product active carbon of physical absorption; Bamboo charcoal; The adsorption capacity of this type of PARA FORMALDEHYDE PRILLS(91,95) polar molecules such as charcoal carving is quite limited; They just possess certain absorption advantage to the air pollutants of the macromolecular particle of nonpolar molecule, because of its release of formaldehyde for up to 3-15.And chemical decomposition method is another method in the market, but cures the symptoms, not the disease.
Sepiolite is rare nonmetallic mineral; Its significant characteristic is adsorptivity, suspension, catalytic, ion exchangeable etc.; The aperture of its distinctive 0.36-1.06 nanometer just is being suitable for taking in harmful polar gas molecule and is living; Therefore the characteristics of the strong adsorption indoor harmful gas polar molecule thing (formaldehyde, ammonia, radon gas, hydrogen sulfide, nitrogen etc.) of this product uniqueness have obtained relevant experts' such as Chinese Indoor Environment Detection center, CDC abundant affirmation, have filled up the market vacancy of sepiolite as air clearing product.But, extremely influenced its specific area (900m because domestic natural sepiolite purity is low, interstitial channels has been full of by many impurity and has tamped
2/ g),, more do not reach the index of air clearing product requirement so domestic natural sepiolite can't reach the adsorptivity of expection.
Summary of the invention
The technical problem that the present invention will solve is; The manufacture craft of further activation modification makes the adsorptivity scavenging material sepiolite air purifying preparation that is used for indoor environmental pollution improvement on the basis of (back sepiolite purity >=80% of the purifying) technology of natural sepiolite being purified in employing Hunan swan goose sepiolite Science and Technology Ltd..
Solution of the present invention is: selecting the purification sepiolite of sepiolite purity >=80% of employing Hunan swan goose sepiolite Science and Technology Ltd. is raw material, presses following technology mode step:

3Agitated reactor equipment is made container, raw material is immersed in the hydrochloric acid solution that concentration is 0.5%-10.6%, the normal pressure of≤0.6Mpa ,-5-180 ℃ temperature under, with rotating speed 48-300f/p stirring reaction 4-24h;
(2), the stirring material that will pass through after the step enters to 5-10m
3In the anticorrosion material storage container of volume, being filtered to pH value through the counter-infiltration of film machine Automatic Extraction, cyclic washing is about 6, places material storage container;
(3), the material that will pass through step process is dehydrated into filter cake through plunger displacement pump, filter press, the moisture content of filter cake is 40-50%;
(4), will go up step processes 33% of filter cake and under temperature 150-300 ℃ condition, is dried to powder through flash dryer; All the other 67% filter cakes get into the chain pulverizer and are ground into fritter, with extruder fritter are processed into the master batch of 0.5-3mm again;
(5), will go up master batch that step processes and add the powder granulation of in rotary pelleting machine, spraying water; The grain that to make again is dried to finished product under temperature 100-500 ℃ in adjustable Rotary drying stove; Its moisture content of finished products is controlled at＜0.3%, press the product cut size screening finished product sepiolite air purifying preparation.
The invention has the beneficial effects as follows: according to the natural network pore passage structure of sepiolite; Permanent negative electrical charge in surface and ion-exchange performance thereof; Carry out acidifying; Heating; Pressurization; The materialization of stirring is handled; The further activation modification of purification sepiolite to the sepiolite purification technique that adopts Hunan swan goose sepiolite Science and Technology Ltd.; Make its duct impurity obtain the acidifying dissolving fully; Guarantee the pore capacities of sepiolite; Impel the sepiolite surface to be permanent negative electrical charge; Process and be used in the adsorptivity scavenging material sepiolite air purifying preparation that indoor environmental pollution is administered; Through detecting; Under equal conditions; The ability of this sepiolite air purifying preparation absorbing formaldehyde substantially exceeds the charcoal series products, clearance >=86%.
The specific embodiment
Selecting the purification sepiolite 800kg of sepiolite purity >=80% of employing Hunan swan goose sepiolite Science and Technology Ltd. is raw material, presses following technology mode step:
