Graphite mold accessories are getting higher and higher

Graphite mold accessories may become higher and higher for high precision regulations. Ten years ago, the precision of precision machinery manufacturing was generally 5 microns. Now it has achieved 2 ~ 3 μm, and the precision of 1 micron precision will be released. This specifies ultra -deep processing. Mobei Industry Chain will be replaced with increasingly importing. This is also caused by the increasingly imported alternative and high productivity regulations of Moden. The multi -purpose compound shell of the machinery processing industry will further develop. In addition to the forming parts of the stamping mold, the new multi -purpose composite mold shellfish also shoulders the daily tasks such as stacking, attacking, riveting and card tightness, and the characteristics of stainless steel plates are also higher and higher.Graphite molds are complete and diverse. Because of its excellent comprehensive ability, you can see it everywhere.

Graphite artificial synthesis

(1) Taking natural scales graphite as raw materials, use Hummers legal oxygen graphite, and use thermal peeling into graphene, or use ultrasonic dispersion to divert into graphene, and then chemically restore into graphene. Use SEM, TEM, HRTEM, XRD, and RAMAN systems to examine the appearance and structure of graphene.(2) Taking graphene as the basis, titanate tetraododes as titanium sources. First, the solution-water thermal legal system is used to prepare titanium dioxide/graphene nano-composite materials. Use XRD, SEM, TEM, and RAMAN to characterize the crystal structure, granular appearance and chemical composition of titanium dioxide/graphene nano -composite materials. The results show that the synthetic titanium dioxide nanocrystal is a sharp titanium structure, the crystalline condition is good, titanium dioxide and graphite The composite effect is better. The photocatalytic performance of nano crystals was studied, and the results showed that titanium dioxide/graphene catalyti

What are the steps of carbon felt purification?

Carbon felt is a major element in many alloy products, so carbon felt purification plays an important role in alloy production. Meanwhile, in the smelting process of metal silicon, silica, ore, etc. are usually used. Silicon slag will also be produced during the smelting process, and silicon slag also contains a certain amount of industrial carbon felt, so we can use carbon felt slag to further purify carbon felt.The first step is to separate the obvious light-colored slag and dark-colored slag from the silicon slag with a manual hammer, and then use the separation principle to further separate the silicon content in the silicon slag.Impurities in silicon slag exist in two forms: reduced and unreduced. In industrial silicon, a flocculant composed of Na2O5~50%, SiO250~95% or Na2O5~50%, SiO250~95%, MgO and CaO is added to industrial silicon. With 35% flux, the melting point of the slag can be reduced from the original 1450 to about 1480 and then down to about 1000. It can also reduce th

Characteristics of graphite crucibles

Graphite crucibles have good thermal conductivity and high temperature resistance. During high-temperature use, their coefficient of thermal expansion is small, and they have certain strain resistance for rapid heating and cooling. Strong corrosion resistance to acid and alkaline solutions, with excellent chemical stability. Graphite crucibles, due to their excellent performance, are widely used in industries such as metallurgy, casting, machinery, and chemical engineering for the smelting of alloy tool steel and the melting of non-ferrous metals and their alloys. And it has good technical and economic effects. The production of domestic graphite crucibles has reached or even exceeded that of imported crucibles:1. The high density of graphite crucibles enables them to have good thermal conductivity;2. The graphite crucible has a specially made and dense molding material on its surface, greatly improving the corrosion resistance of the product and extending its service life;3. The ther

What should be paid attention to when processing refractory materials with flake graphite?

Production process of electric carbon products

(1) Raw materials. The raw materials used in the production of electrochar products include carbon and graphite powder, metal powder, and binder.(2) Calcination. The calcination of petroleum coke used in the production of electric carbon products generally adopts electric calcination.(3) Ingredients. According to the performance requirements of electric carbon products, 4-5 solid powders are used as ingredients.(4) Material mixing. Mixing mainly uses dry mixer, dual axis stirring knife mixer, pressure mixer, and continuous mixer.(5) Rolling sheet. The paste prepared with coal tar pitch as the binder needs to be processed by rolling to ensure the uniformity of the mixing of various materials.(6) Grinding powder. Grind the kneaded material and rolled sheet material to obtain pressed powder.(7) Pressing.
