Also used in the friction material.The particle size can be according to customer requirements.
- Q:The difference between silicone and silicone?
- Silica gel and grease are helpful to system cooling material, the difference is that the silica gel with good thermal performance and insulation, and will not lose its stickiness pale yellow translucent glue at higher temperatures, mainly used in the surface of the heat radiating sheet sticking device; and the grease is not sticky, is a liquid emulsion or cream like, its role is to fill the gap between the chip and the heat sink, improve the efficiency of heat conduction.
- Q:Can graphite be made directly from graphite powder? How about the effect?
- Let the graphite powder stick into shape. The commonly used asphalt in the industry is used as binder, and graphite powder and asphalt are mixed and pressed to form. It is also necessary to heat, roast and graphitized the asphalt in the graphite blocks to obtain certain heat conducting, conductive or other uses of Shi Mobang.
- Q:Are graphite and carbon black the same?
- But they are not the same as the atomic structure, physical properties are not the same, the graphite conductive carbon black than how many times, lubricating graphite is much higher than carbon black, graphite and carbon black light can be separated from these two points is not the same, there are more different places.
- Q:Thermal conductivity and density of graphite powder
- In the formula, P is porosity, and lambda 0 is the thermal conductivity without hole (P=0). This formula is of historic significance. For graphite, the pores are not spherical or more unequal, but of course they do not apply. But it shows that the larger the porosity (the smaller the density), the smaller the thermal conductivity. This qualitative conclusion is correct. An extruded graphite core with different impregnation treatments
- Q:How to measure the conductivity of powdered graphite?
- Voltammetric measurement of resistanceMethods: using precision small range measurement of electricity meter, multimeter resistance or contrast test you can use small bulbs, according to the brightness of his conductivity, if the bulb is more bright, that resistance is lower.
- Q:Is oxygen allowed in the oxygen pipe?
- The so-called oxygen pipeline, which depends on the medical or edible, or industrial oxygen pipeline. If it is industrial, a little graphite is possible, but the proportion can not be too large
- Q:What is graphite powder?
- 1) high temperature resistance: Graphite melting point of 3850 + 50 degrees, boiling point is 4250 degrees, even after the ultra-high temperature arc ignition, the weight loss is very small, the thermal expansion coefficient is very small. The strength of graphite increases with the increase of temperature, and the strength of graphite is doubled at 2000 degrees centigrade.2) conduction and thermal conductivity: the conductivity of graphite is one hundred times higher than that of ordinary non-metallic minerals. Heat conductivity exceeds steel, iron, lead and other metal materials. The coefficient of thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, the graphite becomes hot.3) lubricity: the lubricity of graphite depends on the size of graphite scales. The larger the scale, the smaller the coefficient of friction and the better the lubricity.4) chemical stability: graphite has good chemical stability at room temperature, and can resist acid, alkali and organic solvent corrosion.5) plasticity: the toughness of graphite is good, but it can be a very thin slice.6) thermal shock resistance: when graphite is used at normal temperature, it can withstand the drastic change of temperature without damaging. When the temperature changes suddenly, the volume of graphite changes little and no cracks occur.
- Q:Can graphite powder be used as a carburizing agent?
- You can consult the Qingdao permanent Carbon Industry Co. Ltd. is a professional, they do carburetant, buy their products never mind, you can consult, will give you a very good answer, their service is pretty good
- Q:Does graphite allow lubrication of rusted doors?
- Tolerable。 However, there is a premise: rust must be removed with rust.Lock force rust is generally not easy to lock inside the material easily rust off, then need to use oil to rust, rust removing, the graphite powder filling hole, and then the key to rotate back and forth, you can make the door lubrication.
- Q:How do you use graphite powder in copper?
- It is to drill holes on the copper block and pour the graphite into the hole to ensure that the stone toner can not run out and play the role of oil-free lubrication
