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:Why is there a range of electrode powder powder resistivity? The reasons for the high and low are not good.

Powder resistivity tester, the sample broken to 0.3 ~ 0.5mm, into the powder resistivity instrument insulation sleeve, the tube diameter of 16.3mm, in the bushing into the sample.

Q:Are graphite powders soluble in water, dilute acids, dilute bases, and organic solvents?

Reacting with oxygen at different temperatures to produce carbon dioxide or carbon monoxide; only fluorine in the halogens can react directly to elemental carbon;

Q:Two simple physical methods are used to identify iron powder and graphite powderHurry up, you need it urgently! Thank you

First, with a magnet, you can use a magnet, can be sucked into the iron powder.Two, put in the water, floating above the sink in the bottom of the graphite powder, iron powder

Q:Main ingredients of graphite powder?

These impurities often appear in quartz, pyrite, carbonate and other minerals.

Q:The difference between silicone and silicone?

The characteristics of silicone grease:The application of silicone grease is more widely than silica gel. Many industrial heat places are using thermal grease. Many different types of people and grease, by adding some "impurities" to its thermal conductivity to improve pure thermal grease. These impurities are graphite powder, aluminum powder, copper powder, silver powder and so on. Pure pure silicone is pure white or milky white, the color of the doped graphite grease dark black, doped with aluminum grease some gray shiny, slightly gray is silver, and copper doped grease are yellow or yellow.Now some high-grade thermal grease using silver or aluminum powder as filler, with high thermal conductivity of the metal, but relatively large metal particles, filling effect is poor, the performance increase is not large, but the improper use of conductive grease, easy to cause a short circuit.

Q:Whether the ordinary graphite powder is sprinkled on the electronic instrument can lead to the malfunction of the instrument

Ordinary graphite powder is also conductive, but only strong and weak

Q:How to measure the iron content in graphite powder?

Excessive amounts of dilute sulphuric acid can be used to measure the amount of gas produced, and then the amount of iron is calculated according to the amount of gas.

Q:What binder does the graphite powder form with?

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:How much is one graphite used as electrode?

Graphite particles 6800 yuan / ton, graphite fine powder 8000 yuan / ton, you buy 30 yuan / kg is the natural graphite powder? Not made of graphite electrodes. The graphite powder used in the electrode is actually synthetic graphite powder.
