Description

The ceramic nozzle that a kind of boron carbide-zirconium oxide is combined
Technical field
The present invention relates to boron carbide component preparing technical field and in particular to a kind of boron carbide-zirconium oxide be combined pottery Nozzle.
Background technology
Ceramic nozzle from eighties of last century nine when the age introduce China since, material constantly improves renewal, from oxide pottery Porcelain gradually develops into nitride ceramics and carbide ceramics, and production technology and preparation method fall behind, and causes pottery in prior art There is many defects in porcelain nozzle, such as hardness is not high, wear no resistance, anticorrosion fluid erosion prevention ability is weak, ductility is little etc..For gram Take the deficiencies in the prior art it is necessary to be improved to existing ceramic nozzle production technology, thus be obtained being suitable for different demands There is low cost, function diversification, the ceramic nozzle of the function such as fire-retardant, hardness is high, wear-resisting, radioprotective.
The advantage that boron carbide projects is that density is low, hardness is high and neutron absorption cross-section is big, mainly with boron carbide ceramics material Form application.Boron carbide combines because of strong covalent bond, and self-diffusion coefficient is low, and sintering is difficult.Generally adopt hot pressing or heat etc. quiet Pressure sintering just enables densification.But, one side hot pressing and high temperature insostatic pressing (HIP) can only prepare be relatively small in size, simple shape Product, the manufacturing cost of still further aspect hot pressing and high temperature insostatic pressing (HIP) is high, therefore hinders the application of boron carbide material.
Content of the invention
For achieving the above object, the present invention provides the ceramic nozzle that a kind of boron carbide-zirconium oxide is combined.
The purpose of the present invention can be achieved through the following technical solutions:
The ceramic nozzle that a kind of boron carbide-zirconium oxide is combined, described boron carbide shower nozzle is made up of the material of following weight portion: Nano boron carbide 400-450 part, zirconium oxide 230-335 part, polyphenylene sulfide 10-15 part, molybdenum oxide 2-4 part, aluminum-spinel 4-8 Part, rutile 5-8 part, cryolite 1-2 part, cobaltous sulfate 0.1-0.3 part, potassium feldspar 3-4 part, dolomite 4-6 part, pottery red soil 7-11 Part, potassium nitrate 1-2 part, germanium oxide 3-4 part, Sodium fluoroborate 2-4 part, aluminium nitride 3-5 part, molybdenum disilicide 4-5 part, Kaolin 2-3 Part, volcanic ash 1-3 part, limestone 1-2 part, Talcum 2-5 part, mullite 4-8 part, silicone oil 1-2 part, polyphenylene sulfide 11-14 part, grass Wood ash 0.5-0.7 part, glass fibre 0.3-0.5 part, esterification liquid pectin 2-6 part.
Described boron carbide shower nozzle is made up of the material of following weight portion: 420 parts of nano boron carbide, 300 parts of zirconium oxide, polyphenyl 12 parts of thioether, 3 parts of molybdenum oxide, 5 parts of aluminum-spinel, 5 parts of rutile, 2 parts of cryolite, 0.2 part of cobaltous sulfate, 3 parts of potassium feldspar, white 5 parts of marble, 10 parts of red soil of pottery, 1 part of potassium nitrate, 3 parts of germanium oxide, 3 parts of Sodium fluoroborate, 4 parts of aluminium nitride, 4 parts of molybdenum disilicide, kaolinite Soil 2 parts, 2 parts of volcanic ash, 1 part of limestone, 3 parts of Talcum, 5 parts of mullite, 1 part of silicone oil, 13 parts of polyphenylene sulfide, 0.6 part of plant ash, 0.4 part of glass fibre, 3 parts of liquid pectin of esterification.
Described preparation method includes following making step:
1., raw material mixing: take above-mentioned raw materials according to percentage by weight, by boron carbide mixed-powder with maltose syrup with weight The ratio mixing than 5:1 for the amount, stirs, and final effect is that finger gently pinches energy Cheng little Tuan；
2., the compacting pretreatment of material, pelletize: the boron carbide stirring mixed-powder is loaded alloy mold, with cold Press is pressed into pie, and compacting every time loads and the isopyknic boron carbide powder of die hole, and pie boron carbide is passed through 80 Purpose stainless steel sift sieves into graininess；
3., heat treatment: using Median frequency sintering stove heat, start shooting, power is adjusted to 120kw/h heating, heat time heating time is little for 1 When 35 minutes, temperature reaches 2200 DEG C, voltage instability in pilot process, will adjust the power it is ensured that 120kw/h at any time, in stove Temperature starts when reaching 2200 DEG C to be incubated, and by power decreasing 10kw/h, temperature retention time is 20 minutes within every 5 minutes；
4., suppress cold cut molding: insulation starts after terminating to pressurize, and pressurizes to Intermediate frequency sintering furnace by Remote control valve, plus Press first 10 minutes and be at the uniform velocity pressurized to 10mpa, then remain a constant speed within 5 minutes and be pressurized to 15mpa, whole pressure process about 15 minutes, Start pressurize 5 minutes, finally shut down, about 20 minutes whole press times, finally by recirculated water to body of heater cooling shaping.
Beneficial effects of the present invention: the present invention passes through to improve composition of raw materials and technique, maximizes favourable factors and minimizes unfavourable ones, enhances product strong Degree, has fabulous heat-proof combustion-resistant, weatherability, the performance such as corrosion-resistant, wear-resisting simultaneously.
Specific embodiment
