Q:Does the pencil core go into the baby's face to keep the skin tight?

One possible problem is that even if there is no breakage, but there may be residual graphite powder cartridge inside, more so, good after the wound will leave behind a black spot (a little like the indistinct).

Q:Use of carburizing agents

The particle size is too fine, easy to burn, too coarse, float on the surface of liquid steel after adding, and it is not easy to be absorbed by steel. The particle size of 0.2-6mm in the induction furnace, the steel and other ferrous metal particles in 1.4-9.5mm high carbon steel, low nitrogen, particle size in 0.5-5mm, and according to the specific needs of the furnace smelting specific types of workpiece so the details of specific judgment and selection.

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:The difference between silicone and silicone?

Characteristics of silica gel:Silica gel is a one component, room temperature vulcanized liquid rubber. Once exposed to air, the silane monomer condensed, forming a network structure, crosslinked, unable to melt and dissolve, elastic, rubbery, and adhesive. The thermal conductivity is slightly higher than the general rubber, but compared with the thermal grease is much lower, and once cured, it is difficult to separate the adhesive objects, generally can only be used in graphics cards, memory radiator. Mainly used in silicone adhesive low-end card heat sink and the main chip, bonding and particles, particles of the memory memory and radiator. The high-end products are generally used to dissipate heat with grease, and then use the clip fins fixed on the substrate, but it will increase the cost of. The radiating fins are fixed in the low-end graphics chip and good memory particles, and the heat sink in the low-end graphics cards generally are relatively small, so the use of silicone adhesive is common; and high-end graphics and the CPU heat is far greater than the general low-end graphics chip and memory particle heat generation, and the head is relatively CPU so, the grease with radiator and clip form. If used on the CPU will cause overheating, and it is difficult to remove the heat sink, pull down, it may directly damage the CPU or CPU socket. And if you pull down the silicone adhesive cards, heat sink, it is possible to display the chip from the PCB pull down. From this point, we can see who has a better heat conduction effect.

Q:The axis and drum can use graphite powder lubrication

Of course, you can not use graphite lubrication, it will damage your parts. You can still use grease or butter, and the middle axle is better with butter

Q:What are the hazards of inhalation of graphite dust?

Personally think: black carbon on the human body, and the extent of the time has a lot to do with. On the human body caused by short-term damage is limited to a certain extent, can be restored (but the inhaled particles are difficult to be excreted); over the long term, great harm to the human body, but also can not be restored. Heavy inhalation of carbon black dust can at least cause carbon black, dust, and lung disease (occupational disease, pneumoconiosis). Included in the pneumoconiosis in China: silicosis, coal worker's pneumoconiosis pneumoconiosis, graphite, carbon black pneumoconiosis, asbestosis, talc, mica, cement pneumoconiosis pneumoconiosis pneumoconiosis, Potter's pneumoconiosis, aluminum pneumoconiosis, welders' pneumoconiosis, graphite pneumoconiosis etc.)! At present, the world's lack of treatment for pneumoconiosis, suffering from pneumoconiosis equivalent to sentenced to death. The number of pneumoconiosis patients in our country is equal to that of pneumoconiosis patients in other parts of the world. Please pay more attention to it and don't inhale any more

Q:It's hard to remove a lot of graphite powder on the glass cake. Who has a good way to remove the graphite powder above?

Just add some water and rub it over and over again with wooden sticks or bamboo strips. The effect will be better with water. Do not use hard objects such as glass bars, or your glass becomes a flower.

Q:Is the graphite powder produced with sulphuric acid?

Graphite powder can smash through physical production method, also can be produced by sulfuric acid and other chemical methods, according to different types of graphite powder, the production process is not the same, I hope there is help for you, hope to adopt, thank you.

Q:How does graphite powder solidify into a lump? What bond is best used?After solidification can be more than 1000 degrees high temperature does not change

There is no binder that can withstand 1000 degrees C. At such a high temperature, any binder has been carbonized and has lost its bond effect, so it is impossible if you want to use the binder to make the graphite powder into pieces

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
