Abstract
The invention provides a silicone material recycling method, which comprises: crushing silicone into blocks; grinding the blocky silicone into powdered particles; oscillating in ultrasonic waves to improve the dispersibility of the powdered silicone material; filtering out the water in the powdered silicone material; drying the powdered silicone material; and adding a proper amount of the powdered silicone material into a raw material for forming. In the invention, the silicone waste material can be directly added into the raw material for forming for use after being processed by a simple processing process without influencing the appearance of products, so the consumption of production raw materials is lowered, and environment pollution is avoided.
Description
Technical field
The present invention relates to the material recovery method for using, specifically a kind of silica gel material reclaims method for using.
Background technology
In manufacturing industry, many products that utilize silica gel material as raw material production are arranged, this silica gel goods are transparent, soft, have elasticity, cover the outward appearance that the other products surface can decorative product, and the protection product is not damaged.
Because the silica gel goods generally cover product surface, the client is very strict to the requirement of its outward appearance.During production, the big apperance defective products defective of generation can not circulate on market, also can't directly recycle; Often all be the method that adopts distillation by the recovery company of specialty, decompose silicone oil, and then synthetic the recycling; This kind method processing technology is complicated, and needs the outer processing charges of manufacturer's disbursement, has increased the cost that product is made; Polluted environmental resource, the producer has been caused great puzzlement.The defective products and the waste material that produce during so how more effective recycling produce just become a problem that needs to be resolved hurrily now.
Summary of the invention
Because above-mentioned problem, the silica gel waste material that produces in the manufacturing industry needs to handle through complicated processing technology, could recycle aborning.The objective of the invention is to overcome the deficiency and the defective of prior art, provide a kind of silica gel material to reclaim method for using.
The present invention provides a kind of silica gel material to reclaim method for using, comprises silica white is broken into bulk, again block silica gel is ground to form the powdery particle; Vibration through ultrasonic sound wave; Improve the dispersiveness of this granular colloidal silica material, filter the moisture in this granular colloidal silica material then, and dry this granular colloidal silica material; Further reduce its contained moisture, at last this granular colloidal silica material is added among the used raw material of moulding in right amount.
More excellent, this granular colloidal silica material of said oven dry placed this granular colloidal silica material under 60 ℃ to 80 ℃ the temperature dry 1 hour to 2 hours.
More excellent, this granular colloidal silica material is added among the used raw material of moulding in right amount, the addition of this granular colloidal silica material be this moulding raw materials used 1% to 20%.
Compared with prior art; Silica gel waste material among the present invention is through simple machining process processing; Just can directly add in the shaping raw material and use, and can not influence the outward appearance of product, practice thrift the use of raw materials for production greatly; Improve producer's profit, also avoided the waste material in the commercial production to the natural environment produced pollution simultaneously.
Description of drawings
Fig. 1 reclaims the process chart of method for using for silica gel material of the present invention.
The specific embodiment
For specifying technology contents of the present invention, structural feature, explain in detail below in conjunction with embodiment and conjunction with figs..
See also Fig. 1, reclaim the process chart of method for using for silica gel material of the present invention.
At first the silica gel material of recycling 10 is put into pulverizer and carry out step 101, this silica gel material 10 is ground into bulk.
Carry out step 102 then, the silica gel material 10 that the utilization flour mill should bulk grinds to form the powdery particle.
Next carry out step 103; This granular colloidal silica material 10 is put into ultrasonic sonic oscillation groove,, improve the dispersiveness between this granular colloidal silica material 10 through the vibration of ultrasonic sound wave; The silica gel material 10 that prevents this powdery is bonded together, and influences the manufacturing procedure of postorder.
Next carry out step 104, filter out the moisture in this granular colloidal silica material 10.
Also need carry out step 105, the silica gel material 10 of this powdery is placed under 60 ℃ to 80 ℃ the temperature fully dry 1 hour to 2 hours; Dry under 60 ℃ to 80 ℃ temperature; The silica gel material 10 that can guarantee this powdery has been practiced thrift the production time with the fastest speed oven dry, has improved the efficient of producing; Can prevent also that simultaneously dry temperature is too high, the variation that the silica gel material 10 of powdery is taken place on the physical aspects.
Carry out step 106 at last, in the raw material of moulding, insert this granular colloidal silica material 10 of 1% to 20%, the granular colloidal silica material 10 that inserts this ratio can not influence the outward appearance of product.
Embodiment: during mixing double centner molding mass; In raw material, add 10 kilograms silica gel waste material; This silica gel waste material through above-mentioned 101,102,103,104,105 treatment process, is processed into dry granular colloidal silica, and adds in the raw material this granular colloidal silica mixing.The raw material that this recovery silica gel material has been added in use carries out moulding, can not influence the outward appearance of product.
In the present invention; The silica gel material of recycling is through simple machining process processing; Just can directly add in the shaping raw material and use; Practice thrift the use of raw materials for production greatly, improved producer's profit, also avoided the waste material in the commercial production to the natural environment produced pollution simultaneously.
The above is merely preferred embodiment of the present invention, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all covered by the scope of claims of the present invention.
