The Function and Conditions of Adhesive

Carbon graphite material is a powder structure material similar to refractory materials and concrete. Except for non-ferrous brushes and mechanical metal graphite products, which are formed as a whole with a certain strength by phase transformation of metal powder at sintering temperature, the powder particles of typical carbon graphite materials cannot spontaneously bond together even at high temperatures. In order for them to bond into a whole with a certain shape and strength, a certain amount of substance that can bond carbon powder particles or fibrous fine substances into a whole must be added, and this substance is called a binder.The conditions that the adhesive should meet:1) The adhesive should be able to mix with the main material to form a plastic substance.2) The binder becomes a viscous liquid within an appropriate temperature range. And it can have good adhesion and adsorption with the particles of the main material, and has a large adsorption force.3) The binder should

Graphite mold for antioxidant treatment

1. Heating and conductive: The heterogeneity of graphite is 300 times that of the normal non -non -non -metal mine. Conductivity surpasses non -metal materials such as steel, iron, lead. The conductivity coefficient increased with a decrease in measure, and even at a high degree, graphite became armatologist.2. Chemical stability: Graphite is excellent chemical stability at normal temperature, and the erosion of acid, alkali resistance and inorganic solvents.3. Smooth: The smooth function of graphite originated from the size of the graphite scales. The larger the scales, the smaller the conflict coefficient, and the better the smooth function.4. Plasticity: The graphite is tough and can be crushed into a thin crack. 5. Taxation shock: Graphite can be banned violently at the time of normal temperature and can be banned violently without destruction. When the measurement gradually changes, the volume of the graphite is not large and no cracks will occur.6. Low temperature resistance: T

The production process and use of expansion graphite

The expansion graphite is a loose and porous worm -like substance prepared by the procedure of graphite scales through the intervening, washing, drying, and high temperature. When the expansion graphite encounters high temperature, it can instantly swell 150 ~ 300 times in volume, which changes from sheet to worm -shaped, thereby loose structure, porous and bending, expanded surface area, improved surface can be enhanced. In this way, it increases its softness, return elasticity and plasticity.The expansion graphite is widely used, and the main development directions are as follows:1. Granules expand graphite: Small particles expand graphite mainly refer to 300 purposes that can expand graphite, and its expansion volume is 100ml/g. This product is mainly used for flame retardant coatings, and its demand is very large.2. Expansion of the swelling temperature at height: The starting expansion temperature is 290-300 ° C, and the expansion volume is ≥230ml/g. This type of expansion graphi

Thermal conductivity of polycrystalline graphite

The so-called carbon materials such as artificial graphite molded products are polycrystalline materials with extremely complex structures, and the basic structure of graphite crystallization has strong anisotropy. Therefore, the macroscopic thermal conductivity of carbon materials, apart from relying on empirical data, is almost unpredictable. The factors that have a significant impact on thermal conductivity include:(1) The differences in the basic properties of the initial raw materials;(2) The manufacturing process - macroscopic anisotropy;(3) Heat treatment temperature - the growth degree of graphite microcrystals;(4) Apparent density, distribution of holes, etc.

What should I pay attention to when applying graphite machinery and equipment

1. Be careful when transporting or hanging. Do not drag and drag it on the ground. Do not pry up or use a galvanized steel wire rope to be tied immediately. Essence2. After the total installation, when welding or oxygen cutting of the steel case, it should be ensured that the safety of graphite and hydraulic sealing should be ensured (water can be injected in the shell), otherwise graphite should be removed.3. When connecting the external flanges, it is not forcibly installed. When the foot bolts are tight, the symmetry is symmetrical.4. The export and export valve of the opening and closing machine equipment should be slow to prevent the significant impact of raw materials.5. The application of materials, temperature and work pressure in applications should be strictly strictly in accordance with the requirements of the design plan.6. For the electric heater, when driving, you should first pass the raw material and pass the vapor; when used as a cooling or cooler, you should first pa

Graphite crucibles have good thermal conductivity and high temperature resistance

Graphite crucibles have good thermal conductivity and high temperature resistance. During high-temperature use, their coefficient of thermal expansion is small, and they have certain strain resistance for rapid heating and cooling. Strong corrosion resistance to acid and alkaline solutions, with excellent chemical stability.But the following points should be noted:1. To avoid damage to the graphite crucible caused by impact or falling from a height. Be careful when using, handle with care, and take a look at the surrounding environment.2.
