Abstract
The present invention is gypsum mold slip casting process of preparing high melting point polymerized material crucible, and the produced crucible is suitable for use in producing glass fiber. The process includes the steps of: compounding material, ball milling, drying, pelletizing, heat treatment, ball milling, stoving, compounding slurry, injection molding, trimming, medium temperature treatment, punching and shaping, sintering and inspecting. The present invention has the positive effect of producing crucible with smelting point as high as 2000 deg.C, high heat shock resistance, high breaking strength, small heat expansion coefficient.
Description
Technical field
The present invention relates to a kind of method of utilizing the gypsum mould grouting legal system to be equipped with high melting polymerized material crucible, the crucible that utilizes the present invention to prepare is applicable to the production reinforced plastic glass fibre.
Background technology
Crucible is the most important equipment that crucible method is produced glass fibre, directly influences output, quality, power consumption and the glass fiber wire-drawing fineness of product.
At present, mainly adopt fire clay bushing, but because the production glass fibre is of poor quality, energy consumption is high, relevant department has prohibited the application of this product.The domestic manufactory that economic strength arranged produces glass fibre and adopts platinum crucible, (about 400,000 yuan every), power consumption big (9.5 degree/hour), production efficiency low (about 6.5kg/hour) and have a power failure to scrap and can not open use once more but it costs an arm and a leg.
Summary of the invention
Technical problem to be solved by this invention provides a kind of crucible that produces that can make and has the fusing point height, and thermal shock resistance is good, rupture strength is high, and the gypsum mould grouting legal system of utilizing that thermal coefficient of expansion is low is equipped with the method for high melting polymerized material crucible.
The technical solution adopted for the present invention to solve the technical problems:
Technological process of the present invention is followed successively by: batching, ball milling, drying, granulation, heat treatment, ball milling, oven dry, preparation mud, injection molding, finishing, middle temperature are handled, the punching integer, burn till, pick, finished product;
Its concrete preparation method is as follows:
(1) batching:
A, choose following each raw material by weight percentage:
JS high melt polymeric material: 95%-99%
Rare earth: 1%-5%;
B, will go up proportion raw material and mix;
(2) ball milling, drying, granulation:
With the raw material after above-mentioned the mixing through ball mill ball milling 14-18 hour, then 110 ℃ ± 5 ℃ dry 22-26 hour, cross 150 mesh sieves through mechanical selection by winnowing afterwards and get particle;
(3) heat treatment:
Heat treatment process is: be warming up to 1100 ℃ ± 10 ℃ through 16-18 hour, insulation was 3-5 hour under this temperature, was cooled to room temperature then through 22-26 hour;
(4) ball milling, oven dry:
With the material ball milling after above-mentioned heat treatment 14-18 hour, 110 ℃ ± 5 ℃ oven dry 46-50 hour;
(5) preparation mud, injection molding, finishing:
It is that the moisture content of 30%-60% is made mud that material after the above-mentioned oven dry is added percentage by weight; Injection molding, finishing then;
(6) temperature processing in, punching integer:
Treatment temperature is 900 ℃ ± 5 ℃, and the processing time is 46-50 hour; The integer of punching then;
(7) burn till:
Firing condition is: temperature: 1540 ℃-1550 ℃, and time: 46-50 hour;
(8) pick gets qualified finished product.
The invention has the beneficial effects as follows that the crucible that utilizes the present invention to produce has fusing point height (2000 ± 10 ℃), thermal shock resistance good (1650/20 ℃ 38 times do not split), rupture strength height (135MPa), thermal coefficient of expansion is low by { 0.16～0.6 * 10
-6/ ℃ (RT～1000 ℃) }.
The specific embodiment
Embodiment: operate to draw qualified crucible by the technical scheme described in the foregoing invention content part.
Wherein, in burden process, according to the form below requires to choose each raw material:
Annotate: (1) above-mentioned percentage by weight that the ratio of each component is
(2) the JS high melt polymeric material is the new material of Qinghe Refractory Material Group Co., Ltd., Hebei Prov by Chinese patent: CN1807255A and the disclosed contents production of CN1807256A.
Every physical and chemical index such as following table by the prepared crucible of the foregoing description:
| The porosity (%) | Close (the g/cm of body 3) | Rupture strength (MPa) | Thermal conductivity factor (w/m.k) (600 ℃～800 ℃) | Thermal coefficient of expansion/℃ (RT～1000 ℃) |
| 3～6 | 3.0～3.89 | 60～135 | 1～1.5 | 0.16～0.6×10 -6 |
