Introduction of high purity sagger and our produce’s advantage
Graphite saggers, graphite boats, and troughs are widely used for lots of things: sintering battery powder materials, forming precious metal ingots, heating and sintering electronics, high temperature liquid containers in laboratories, etc.
High temperature and corrosion resistance, excellent thermal conductivity, and uniform high temperature dissipation make it an excellent industrial high temperature heating vessel. The products are available in sizes ranging from 10mm to 1000mm depending on the demands of different customers.
Here’s what makes our graphite products stand out.
1. Ensures thermal stability: Special treatment assures product quality under rapid temperature changes.
2. Resistance to erosion: The material’s uniform structure delays erosion.
3. Defiance to impact: High thermal shock strength, so the process can be done safely.
4. Acid defiance: Adding special materials improves the physical properties of the material, provides excellent acid resistant, and extends its service life.
5. Thermal conductivity: The high content of fixed carbon secures superior thermal conductivity, shortens the dissolution time, and saves energy.
6. Composition control: Strict composition control keeps contamination to a minimum.
7. Stability: Uniform isostatic forming’s production technology and quality control system make it more stable.
Formulation and pressing method of graphite made sagger
Sintering saggers require high density, high carbon content, low ash content, and high flexural and compressive strength for negative electrode materials.
FS Graphite’s sagger formula can meet the following requirements:
Density: 1.75
Carbon content : 99.9
Folding resistance: 30 MPa
Compression resistance : 80 MPa
There’s nothing complicated about pressing.
This process requires a 1,000-ton hydraulic press, a split mold, graphite powder, asphalt, cellulose, binder, catalyst, and more.
1. Mix high purity graphite powder (400 mesh), asphalt powder (200 mesh), ketone-based binder, and cellulose in a ratio of 100 to 15 to 6 to 5, stir well, and then heat.
2. Into the press for molding, demoulding, then drying. After drying, the hardness can reach 40.
3. Put into asphalt impregnation tank, impregnation temperature 220 degrees, first negative pressure for an hour, then pressurized 10 MPa for an hour, scrape off asphalt solution residue, roast graphitization, add graphitization catalyst, so roasting and graphitization are done at the same time.
A temperature of 200 degrees is used to carbonize cellulose, and then a temperature of 300 degrees so that asphalt enters the coking phase, and then a temperature of 1600 degrees is used to activate the graphitization catalyst, so that low-temperature graphitization commences, the mantle is generally 10 mm thick, and it takes up to 30 hours to kindle the graphitization process, and then a temperature of 300 degrees is used to shrink the material in a 4-5% range.
There will be a reduction in size, an increase in density, a reduction in resistance, an increase in bending and compression, and improved mechanical properties.
