Q:What solvent can be used to dissolve Teflon?
Market suspension of PTFE fine powder. It can be mixed directly with graphite powder without dissolving. It can press molding and sinter products.
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:How to measure the iron content in graphite powder?
Take a certain amount of samples, adding dilute hydrochloric acid, excessive filtering and drying. The quality of the filter residue. By weighing the quality of the sample quality is the quality of minus slag containing iron. With this value divided by the sample quality, the mass fraction of iron.
Q:Is graphite powder dangerous?
Graphite powder graphite is a kind of battery cathode materials. The process of graphite powder, will after the bursting of the raw ore by car to crush the rock breaking machine, and ball mill by flotation, the flotation of graphite ball mill grinding wet material sending selected, will be selected to dry the wet material bagging machine dry a shower, shower is dry, dry graphite finished product.
Q:Antistatic concrete with graphite powder and conductive carbon black, which effect is good?More specific. I don't quite understand
The better conductivity is graphitized carbon, the higher the degree of graphitization, the better the conductivity. In general, the conductivity of graphite is better than that of black carbon (both of which are of high purity, if not of high purity).
Q:Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.
Dust explosion condition(1) flammable dusts are suspended in the air at proper concentration to form dust clouds which are often called;(2) adequate air and oxidizing agents;(3) there is fire or strong vibration and friction. Generally believed that the explosive dust as long as the conditions (1) and conditions (2), it means that there are possible signs of the accident.
Q:For thermal grease skills, the more detailed the better
If the fins and the metal cover of the CPU are as smooth as mirrors, they will be 100 percent fully exposed to the best thermal conductivity.
Q:The graphite powder production process and the graphite production process are introduced briefly Graphite powder production process, graphite production process, detailed technical parameters where?
Mainly used in rough rolling, crushing, crushing for hard materials and bulk material; cut is mainly used in crushing, grinding for ductile material; impact is mainly used in grinding, fine grinding, fine grinding, suitable for brittle material grinding; grinding mainly in fine grinding and superfine grinding, suitable for crushing small block and fine particles.
Q:Why is the battery electrolyte more potassium hydroxide and sodium hydroxide is less used?
When the ambient temperature is low, the potassium hydroxide solution is used at a density of 1.19 to 1.21 (15 DEG C).
Q:How to measure the conductivity of powdered graphite?
The conductive effect of graphite powder is an important factor in making conductive products, so it is very important to know the conductivity of graphite powder.Graphite powders have high electrical conductivity. And stone toner conductivity is an important factor in graphite powder conductive products. There are many factors affecting the conductivity of conductive graphite powder, such as the proportion of graphite powder, external pressure, humidity of the environment, humidity and even light.
