Abstract
A high-activity molecular sieve in the form of blocks is prepared from the raw molecular sieve through loading in metallic container, heating to 450-550 deg.C at 0.3-0.5 deg.C/min in vacuum furnace, holding the temp for 2-10 hr, vacuumizing to 1.0-1.5 Pa, cooling, restoring ordinary pressure, and coloring to obtain its product, which is used for clenaing indoor air. Its regeneration process is also disclosed, which is similar to its preparing process.
Description
Technical field
The present invention relates to have the production method and products thereof of block molecular sieve goods of strong adsorption function and the renovation process of product.
Background technology
In the prior art, though people begin to utilize the adsorption function of molecular sieve already, its range of application is very little, is mainly used in drying, purification, the Catalytic processes of laboratory and some chemical products and keeps miniature precision instrument drying.Along with the raising of The development in society and economy and quality of life, environmental protection is more and more generally paid attention to.The various harmful poisonous gas that hotel, office, commercial building, amusement venue, classroom, household's house fitting, ornament materials discharge, the smog that smoking, fuel produce, indoor foul atmosphere is serious harm people healthy all, demands urgently purifying.
It is Powdered or as the graininess of mung bean size that prior art is used for adsorbing zeolite product, can not be used as harmful poisonous gas in the absorbed air, the environment-friendly type decoration of bettering people's living environment, finishing material and artistic product.
Summary of the invention
The technical problem to be solved in the present invention is, described problem at the prior art existence, the method of reproducing of preparation method of the strong active block molecular sieve goods of proposition and products thereof and product, its preparation method can be produced has the block molecular sieve goods of the strong activity of harmful poisonous gas in the powerful absorbed air, utilize method of reproducing can make the absorption saturated block zeolite product desorption and regeneration of strong activity and realize being repeatedly used, to become product can be various section bars and finishing, decorate, handicraft, for providing, people have harmful poisonous gas in the powerful absorbed air, the environment-friendly type that the has the decorations aesthetic feeling again product that purifies air, thus environmental quality improved, safeguard physically and mentally healthy.
One of technical solution of the present invention is that the technical process of the block molecular sieve goods of described strong activity preparation method is:
(1) granularity is made block elements base just for 200-300 molecules of interest sieve powder stock, described molecular sieve raw material is one or more in 5A, 6A, the 7A type;
(2) described base is just packed in the canister, then canister is put into vacuum drying oven, make vacuum drying oven be warming up to 350 ℃-550 ℃ again with 0.3 ℃/minute-0.5 ℃/minute speed, insulation is 2-10 hour under this temperature, will be extracted into 1.0-1.5Pa vacuum in the stove in 50-70 minute before insulation finishes;
(3) reduce to room temperature with 0.3 ℃/minute-0.5 ℃/minute speed, again vacuum in the stove is slowly returned to normal pressure in being no less than half-hour period, take out goods, promptly.
Below make and further specifying.
In the aforementioned production method of the present invention, described block elements just base comprises various plates, piece, side, post, tube, sheet and profile shapes, and base at the beginning of the various decoration, finishing, technology, the art work.
The forming method of described base just comprise pressing mold pressure be 2.5-3.5MPa conventional compression molding, water moldings formed therefrom or deerskin glue bond moulding etc.
The molecular sieve powder that described molecular sieve powder raw material comprises existing commercially available molecular sieve powder, be processed into the particulate molecular sieve product etc.
The present invention makes the block elements of certain moulding with the molecular sieve raw material by above processing step, and these goods is become have than the stronger block molecular sieve goods of strong activity of adsorption function as the molecular sieve of raw material.
Two of technical solution of the present invention is, the block zeolite product of described strong activity is, whole of the independent body of the block molecular sieve goods of strong activity that will make or whole of being combined into by a plurality of sub-assemblies by the method for one of technical scheme carry out the conventional artistry of moulding, finishing, increase aesthetic feeling painted, woman's persona, promptly; The available pin of combination of a plurality of sub-assemblies (part), nail connection, deerskin glue bond and common process are realized.
Three of technical solution of the present invention is that the technical process of the block zeolite product renovation process of described strong activity is:
(1) with conventional method that the product surface cleaning is clean:
(2) product is put into canister, again canister being placed vacuum is the vacuum drying oven of 1.0-1.5Pa, makes vacuum drying oven be warming up to 400 ℃-450 ℃ with 0.2 ℃/minute-0.3 ℃/minute speed then, keeps described vacuum and is incubated 4-10 hour;
(3) reduce to room temperature with 0.2 ℃/minute-0.3 ℃/minute speed, vacuum returns to normal pressure in being no less than in the halfhour time stove then, takes out product, promptly finishes regenerative process.
Product surface cleaning in the renovation process of the present invention can not be used liquid.
Renovation process of the present invention by heating and keeping corresponding vacuum and slowly cooling, recovery normal pressure, can make the product desorption effectively, and product keeps original strong activated adoption function after making desorption.
As known from the above, the present invention is the renovation process of strong active block molecular sieve goods preparation method and product and product, and described preparation method can obtain the active block molecular sieve goods of strong adsorption function; Products obtained therefrom is various harmful poisonous gases, smog etc. in the absorbed air in a large number, has effectively purified air, has eliminated environmental pollution, safeguards health, also has the function of finishing, decoration and handicraft, one-object-many-purposes; Described renovation process can make product use repeatedly.
