- Q: Whether the ordinary graphite powder is sprinkled on the electronic instrument can lead to the malfunction of the instrument
- If the graphite powder in electronic instrument, contact electric circuit, it will cause a short circuit or lead to equipment failure, want to know more information and knowledge can be graphite powder, graphite powder to Qingdao Huatai to understand, can understand the causes of graphite powder, instrument failure hope to adopt, thank you L.
- Q: The principle of a graphite missile
- When graphite sticks to point wires, numerous circuits are formed, but they are short circuited.So the circuit was broken.
- Q: Where are the graphite powders sold?
- The graphite powder only local graphite mineral resources have now sold, graphite powder mainly sold through e-commerce channels from the Internet, Huatai graphite powder sales network covering more than 20 cities and counties, we are more than 20 years of graphite powder manufacturers
- Q: Is oxygen allowed in the oxygen pipe?
- To tell the truth, the graphite powder also belongs to small particles, if the medical oxygen pipe can not have graphite, if industrial oxygen, can have the physical and chemical properties of graphite, graphite and other stable, will not react, to a certain extent is a kind of preservatives, prevent oxidation function.
- Q: Know how the colloidal graphite powder comes in
- There are two ways to make colloidal graphite: (1) mechanical method. Natural graphite is crushed and treated with hydrochloric acid and hydrofluoric acid to remove impurities. Added to the aqueous solution of tannic acid, which is repeatedly inverted into paste. Colloidal graphite can be obtained by adding a certain proportion of water and ammonia, and then by ultrasonic treatment to further reduce the particle size. (2) chemical method. After being purified and crushed, the natural graphite is added with concentrated nitric acid and concentrated sulfuric acid and water at 90 DEG C, and then obtained by cleaning, drying, adding water, ethanol, acetone and other dispersing agents to obtain colloidal graphite. Add stabilizer such as sodium oleate, sulfate and so on, so that graphite particles do not agglomerate. Ammonia transfers the graphite colloid to the gum solution and regulates the pH value.
- Q: What if the key is inserted in the hole and can not be drawn out?
- Don't use the strength to Jin qiao. You can also pour cold water into the hole. It's very useful
- Q: What mask should be used to prevent stone powder?
- As enterprise owners, should actively take labor protection measures, do not mean this little money, because if workers suffer from silicosis, treatment and late payment of responsibility is the business owner himself. This runs the risk of.
- Q: Can ultrafine powder iron conduct heat? How many purpose graphite powder can be called superfine stone powder? Pingdu graphite powder which good?
- Ultrafine toner is a thermal conductive function, because ultrafine toner is processed from natural graphite, which inherits the characteristics of natural graphite conduction and heat conduction.
- 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: How can graphite paper be made? Can graphite powder be solidified without brittleness?
- Single layer graphite paper is thin, thickness less than 1mm, strength is low, it is the raw material of electric heating felt and advanced gasket sealing material. It is widely used. The single graphite paper and multilayer plate are rolled into thick composite boardI hope it works for you
