Abstract
The present invention relates to a method which is completely carried out in vacuum. Any kind of materials (marble, rock or other qualities of materials) with various grain sizes and adhesives (organic or inorganic) are put into a mixer(2) to obtain completely uniform mixture, and then are filled into a mould box (1) in a convenient mode which is then transferred to the inner part of a press machine (6). A beam (8) which is provided with a vibrator (10) is arranged in the press machine and simultaneously presses and vibrates a material mass is reduced in volume to form a block-shaped body. The block-shaped body is suitable for being cut into flat plates or building blocks with small dimensions as required.
Description
With the method that the present invention proposes, make raw material with any material (marble, rock and other various types of materials), in conjunction with the binding agent of proper proportion, produces closely knit block, measure less flat board or building block in order to being cut into, supply construction usefulness.
In the patent of addition application first time of the above-mentioned application that disclosures in Italian patent application 82540/A/75 number of submitting on September 15th, 1975 of the applicant and the applicant submitted on April 22nd, 1977 85564/A/77 number, a kind of method is proposed, in airfree environment, use vibrations and pressurization combination, form the bonding building stones of resin chunky shape.
Said method requires to use the building stones fragment that is controlled in the limited range (being 4mm to greatest extent), utilizes shock effect and pressurization combination in no air ambient, makes the intensive of material own, carries out catalysis with the proper method that proposes with the heat of resin then.
The applicant is in the 85558/A/81 number application of submitting on May 7th, 1981, and the crumb size of the marble fragment of use arrives 200mm greatly, has made to measure sizable block and (reach 305 * 125 * 80cm).In the environment of air is arranged,, in mould, pour into a mould jointly the material of control crumb size and the hybrid bonding material supplied with by suitable mixer.Then the mould of such perfusion is placed in the forming press, in forming press, shakes, carry out complete degasification and compacting, up to being completed into block.Block with this mode is made leaves standstill in natural environment usually, perhaps puts into the thermocatalytic that baker produces with resin.
These two methods all have inconvenience, particularly:
First method and its corrective measure require just to need the screening of a shattering process and building stones with very little fragment (being 4mm to greatest extent), thereby have increased the time of preprocessing.Because the stone grain is very little, thereby volume dwindles the ratio of surface area, so that total area coverage becomes is very big, just needs with a large amount of binders.
Second method has overcome the unfavorable conditions of first method, but does not propose any other important feature.Owing to stir and compaction die carries out down in the open, impel the hole formation in the material, lean against merely to shake under the no air ambient and be difficult to eliminate hole.
The object of the present invention is to provide a kind of method that forms building block, use vibrations, compression and vacuum action simultaneously, make the building block of formation have rigidity preferably.
Another purpose of the present invention is to seek to overcome above-mentioned shortcoming, therefore proposes a set of equipment, can use crumb size to arrive the building stones of 200mm and the powder and the fragment of above-mentioned building stones greatly, makes to have quite greatly and measures (the block up to 305 * 125 * 80cm).
In order to realize The above results, therefore must consider some new characteristics of machine and product, these characteristics and former sizable difference arranged.
According to a kind of method that forms building block simultaneously with vibrations, compression and vacuum action of the present invention, it is characterized in that stirring in a vacuum, the building stones fragment of various different sizes, its powder and binder are stirred into fully uniformly mixture, in no air ambient, this mixture is pressurizeed simultaneously and shake.
According to equipment of the present invention, it is characterized in that described equipment comprises: a mixer that above-mentioned fragment and adhesive is mixed into compound, in above-mentioned mixer, above-mentioned compound is stirred to obtain the mechanical device of even compound, accept the mould of described compound from described mixer; Vacuum device in described mixer and described model; One is connected with described model, so that by reciprocating motion and translational motion alternately, and the vehicle that described mould is stirred; One has opening to accept the press of described mould; Article one, the duct that described mould is led to described press; The device that in above-mentioned press, keeps vacuum; The device of compacting simultaneously and the above-mentioned compound of vibrations in above-mentioned press, it comprises a plurality of cylinders that link to each other with a beam, above-mentioned beam is reduced making it to contact so that described compound is produced the device of vibrations and pressure with described compound; Described mould is transported to the device in described duct, and the device that building block is drawn off from described press.
At first, because the material piece of measuring greatly almost can not move itself voluntarily in slurries.This explanation material piece must by an automated procedure sedimentation, therefore reach the end of operation always in model, model can not the shift position in equipment.Secondly, the material piece must make them adjacent to each other in vertical direction under the high pressure effect.
Obviously, in this sessions,, produce sizable friction having between the various constituents of various crumb size (major part has sizable size).
For this power can be allowed, therefore in the pressurization operation, must in mixture itself, cause strong vibrations.
In order to improve the numerical value of the oscillating force that beam sends that is provided with mechanical vibrator, and make in shock energy mixture in operation whole and propagate, mixture must have enough rigidity.
This rigidity must be by the fragment of a large amount of as far as possible various sizes, exists airbag to wait anything but in a small amount of as far as possible binder and the material group itself and guarantees.
When the end of job, must there be hole fully in the material of the block of making.
The major advantage that obtains with this new method is:
1) binder has sizable saving;
2) the main content of product is natural constituents, thereby preferable quality is arranged;
3) it is very big and the block of these characteristics is arranged to form size;
4) can use any building stones of various crumb size and characteristics, thereby whole products of shattering process are utilized.
All processes should carry out in airfree environment, thereby eliminates the possibility that contains air in the product, contains air and can greatly reduce intensity and the quality of finishing product.
The block sclerosis made from this method, method for curing is fixed with the type of used sizing then.In fact used binder can with organic type or inorganic type.
Organic type binder such as phenolic resins, black resin (melanyl resins), urea resin, epoxy resin, mylar etc. require high temperature or low temperature to carry out polymerization, make the own polymerization mutually of molecule possibility of binder; Inorganic bond material such as cement only need to wait for the interreaction voluntarily of various constituents, harden.
