Abstract
The present invention relates to be used for the wax removing powder of field of ceramic processing, disclose a kind of wax removing powder and manufacture method thereof.Wax removing powder provided by the invention is the general industry aluminum oxide, and its meta particle diameter is 80～150 μ m.Make the method for described wax removing powder, described method is: described industrial oxidation aluminium powder is selected the screening of sieving, and screen cloth is a 200-260 purpose oversize, obtains the commercial alumina powder of meta particle diameter 80-150 μ m.Wax removing powder provided by the invention is easily manufactured, draw materials easily, and cost is low, can be recycled often, and long service life can be widely used in fields such as hot die-casting molding base substrate de-waxing, casting method and rolling formation binder removal.
Description
Technical field
The present invention relates to the chemical substance manufacture field, relate in particular to a kind of wax removing powder and manufacture method thereof.
Background technology
The hot die-casting molding method is to add appropriate amount of industrial paraffin in a kind of ceramic powder after calcining, stir into liquid shape slurry through heating again after, be injected into and be condensed into the workpiece industrial ceramics manufacture method of base just in the punching block.Because the product that this method is produced, remove its surperficial slickness, forming tolerance grade is better than outside the methods such as molded method, injection forming, also be particularly suitable for making complex-shaped industrial ceramics, the hot die-casting molding method just is being based on these advantages, made complex part by each manufacturer in the industry, perhaps be extensive use of during the high product of workpiece size accuracy requirement.Yet, this method have the production cycle long, manufacturing process is complicated, manpower and fuel consumption are big, and just base is out of shape when de-waxing, the rimose situation is more serious, causes yield rate shortcoming always on the low side, also is consistent in the industry admitted facts.The core focus that causes aforesaid drawbacks is the performance of used wax removing powder.
When being sintering, wax removing powder is used in the workpiece a kind of packing material between base just, have supporting workpiece just base in the de-waxing process, be in still can keep under the dewax state original appearance constant, absorb the effect that the paraffin liquid that melts vapors away its burning, and have the advantages that do not stick to behind the sintering on the workpiece.In order to remedy the deficiency of hot die-casting method, the insider is seeking a kind of evolutionary approach of wax removing powder always, or research and develop a kind of new wax removing powder and substitute the commercial alumina powder, so that improve yield rate, reduce manufacturing cost, slow down the world fuel survival pressure of bringing to enterprise in short supply.
At present, the wax removing powder that the most manufacturers of exhausted people use all is the general industry powder, the most outstanding deficiency of this powder is that wax removing powder is irregular, particle partially carefully (between the 80-150 order), during use, the mutual interlock that gathers together between the particle forms the arch bridge hole, overall flow is poor, phenomenons such as when causing the workpiece de-waxing, the part that does not have wax removing powder to support under the dewax state is bubbled, cracking, distortion; Meticulous because of particle, the gap during gathering between the particle is little, makes that overall air permeability is poor, thermal conduction is poor, is unfavorable for the volatilization of wax; Often cause idiosome stream wax etc.In addition, particle is meticulous cause workpiece surface to blow powder operation difficulty big, needs to drop into more manpower and go to finish, and dust is seriously polluted greatly.Most importantly, old wax removing powder access times are few, and the life-span is short, need often to change the cost height.
Summary of the invention
Be to solve the problem that prior art exists, the invention provides a kind of de-waxing effective, blow powder easily.Dust pollution is few, the wax removing powder of long service life and manufacture method thereof.
The present invention is achieved in that
A kind of wax removing powder, described wax removing powder are product on the commercial alumina 200-260 mesh sieve, and its meta particle diameter is 80～150 μ m.
Another object of the present invention provides a kind of method of making described wax removing powder, and described method is: described industrial oxidation aluminium powder is selected the screening of sieving, and product on the 200-260 mesh sieve obtains the commercial alumina powder of meta particle diameter 80-150 μ m.
Wax removing powder provided by the invention is compared with existing wax removing powder, because its particle diameter is bigger, the porosity height, adsorptive power is strong, good fluidity, gap during gathering between the particle can be very not little, make overall air permeability, good thermal conduction to help the volatilization of wax, can reduce the waste of manpower and fuel, de-waxing is effective, workpiece yield rate height; And because particle is bigger, so blow powder easily and dust pollution is few; Described in addition wax removing powder can fully surround base substrate, and under binder burnout temperature, not with product generation chemical reaction; Easily manufactured, draw materials easily, cost is low, can be recycled often, can be widely used in fields such as hot die-casting molding base substrate de-waxing, rolling formation binder removal.
Embodiment
Describe the present invention in detail below in conjunction with specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
The wax removing powder that present embodiment provides is a commercial alumina, and its meta particle diameter is 80～150 μ m.
The making method of described wax removing powder is: industrial oxidation aluminium powder is sieved through selecting, and used sieve number is the 200-260 order, and obtaining the meta particle diameter is 80～150 μ m commercial aluminas.
Field of ceramic processing just base is out of shape when de-waxing, the rimose situation is more serious, cause yield rate shortcoming always on the low side, the core focus that causes aforesaid drawbacks is the performance of used wax removing powder, and the particle diameter of wax removing powder is the factor of most critical, in the present embodiment with commercial alumina oversize after the 200-260 mesh sieve divides, the meta particle diameter is between 80～150 μ m, the porosity height, adsorptive power is strong, good fluidity, gap during gathering between the particle can be very not little, make overall air permeability, good thermal conduction helps the volatilization of wax, can reduce the waste of manpower and fuel, de-waxing is effective, workpiece yield rate height; And because particle is bigger, so blow powder easily and dust pollution is few; Described in addition wax removing powder can fully surround base substrate, and under binder burnout temperature, not with product generation chemical reaction.And manufacture method provided by the invention also convenient and simple, draw materials easily, cost is low.
More than the technical scheme that the embodiment of the invention provided is described in detail, used specific case herein the principle and the embodiment of the embodiment of the invention are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as limitation of the present invention.
