Present invention is disclosed a kind of Novel quartz fishbowl, and the quartz glass fish jar selection is reasonable, moderate cost, prepares
Simple process, the melting temperature of its raw material has obtained effective reduction, to carry out melting die casting operation, suitable for various rule are made
The quartz glass fish jar of lattice, and performance is stable.
Embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly defined so as to be made to protection scope of the present invention.
In the Novel quartz fishbowl that the present invention refers to, the fish jar integrally uses low melting point quartz glass material, passes through
Prepared by hot melt extrusion process, main component and its percentage composition proportioning of described tank body of fish tank are:Glass sand
60%-65%, aluminum oxide 20%-25%, boric acid 5%-6%, cerium oxide 1%-2%, arsenic oxide arsenoxide 1.5%-2%, yittrium oxide 0.6%-1%, oxidation
Copper 0.5%-0.7%.
Further illustrate, main component and its percentage composition proportioning of the tank body of fish tank are:Glass sand 62%-
64%th, aluminum oxide 22%-24%, boric acid 5.5%-6%, cerium oxide 1.4%-1.6%, arsenic oxide arsenoxide 1.6%-1.8%, yittrium oxide 0.8%-1%,
Cupric oxide 0.6%-0.7%;The purity of aluminum oxide is 99.995%, and granularity is 200 mesh, for improving the intensity of fish jar and acidproof
Property;The average particle size of the melting time of boric acid, yittrium oxide and cupric oxide for shortening raw material, yittrium oxide and cupric oxide is 500
Mesh;Cerium oxide and arsenic oxide arsenoxide can assign fish jar good light transmission and ability and ultraviolet resistance, and light transmittance is purple up to more than 80%
Outside line transmitance is less than 10%;The fusing point of tank body of fish tank raw material can be controlled in less than 1200 DEG C.
The specific preparation process for the Novel quartz fishbowl that the present invention refers to is as follows:
a)Selection is stocked up, and main component and its percentage composition proportioning of the fish jar raw material are:Glass sand 64%,
Boric acid 6%, cerium oxide 1.6%, arsenic oxide arsenoxide 1.7%, yittrium oxide 1%, cupric oxide 0.6%, remaining is aluminum oxide;
b)Low melting point powder is prepared, process for preparation is as follows:First, by the glass sand in raw material, aluminum oxide, boron
Acid, cerium oxide and arsenic oxide arsenoxide are sent into Muffle furnace and fully fused, and heating and temperature control is at 1700 DEG C or so, melting 4-4.5 hours;
Then, compound is placed in stove to take out after slow cooling 4-4.5 hours and is air-cooled to room temperature;Then, using disintegrating machine to cooling expect into
Row fragment processing, after by fragment be sent into ball mill in ball milling select conical ball mill into powder, ball mill, power of motor is
200KW, spheroid select elliptical shape ball, and material is zirconium oxide, and 40% or so, Ball-milling Time is that 7-8 is small for the loading control of spheroid
When;Finally, the low melting point powder that average particle size is 150 mesh is obtained by screening;
c)Hot-melting and injection-molding, first, obtained low melting point powder and yittrium oxide and cupric oxide are sent into continuous induction melting furnace, furnace temperature control
System is at 1200 DEG C or so, fully melting 1 hour;Then, melting charge is imported and die casting processing, injection ratio is carried out in vacuum die casting machine
Voltage-controlled system is controlled in 18-20m/s in 5.5-6MPa, filling velocity, and mold material is high-temperature resistance die steel HQ-40;Finally, will press
Casting ejects, and in stove slow cooling to room temperature;
e)Post-process, aftertreatment technology is handled and assembled including annealing, deburring and repairing type etc.;Make annealing treatment and be
Two rank isothermal processes, fish jar blank each isothermal holding 1 hour in 400 DEG C and 300 DEG C of two temperature respectively, it is therefore intended that remove
Internal stress and further stability.
Present invention is disclosed a kind of Novel quartz fishbowl, it is characterized in:The quartz glass fish jar selection is reasonable, cost
Moderate, preparation technology is easy, and the melting temperature of its raw material has obtained effective reduction, to carry out melting die casting operation, has been suitable to
The quartz glass fish jar of all size is made, and performance is stable.
