Q:Graphite is widely used in industry and in daily life. It can not be used in industry
Many devices for conveying corrosive media are made of graphite materials, piston cups, seals and bearings. They do not need to be lubricated when running. Graphite is many metal processing (drawing, drawing) the good lubricant.For the production of heat exchanger, reaction tank, condenser, combustion tower, absorption tower, cooler, heater, filter and pump equipment. Widely used in petroleum, chemical, hydrometallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, can save a lot of metal materials.
Q:Procedures for operating high temperature furnaces
A, check the power line contact is goodB, check if the connection is normalC, check if the cooling water is normalD, check the tightness is normalE, prepare the necessary tools: dust-free paper, anhydrous alcohol, canvas gloves, operating gloves, masks, high temperature gloves, graphite trolley, stainless steel tray
Q:What are the advantages of a smelting furnace using induction heating, and will it reduce costs?
The electromagnetic field produced by the electromagnetic oven causes the eddy current at the bottom of the heating pot to produce heat, so the D is wrong. Therefore, AC.
Q:What are the main changes in graphene supercapacitors?
What are the main changes in graphene supercapacitors?"
Q:Graphite used in graphite in the glass industry?
Graphite used in the glass industry, some graphite crucible furnace, because graphite temperature resistance is good, but the graphite products must be anti oxidation treatment.
Q:What's the difference between crucible furnace and non crucible furnace in die casting industry?
The crucible furnace, as the name suggests, is a furnace with a crucible. There are cast iron crucibles, cast steel crucibles, some alloy steel crucibles, graphite crucibles, clay crucibles and carborundum crucibles from the crucible material.
Q:What are the differences between quartz crucibles and glass crucibles in appearance, properties, uses, etc.?
Personally, I think that the short duration of sodium hydroxide in the quartz bottles should be no problem. As long as the inner wall is smooth, it is important to note that the stopper must not be used to grind the plug
Q:What material of graphite is used in arc furnace production?
Today, large diameter semi graphitic carbon electrodes have been adopted in industrial silicon electric furnaces. Can effectively save production costs, and the technology is relatively mature.
Q:Graphite and diamond are elemental elements made of carbon. Why are physical properties so different?
Purpose: GraphiteIn the metallurgical industry, used in the manufacture of graphite crucible and foundry mold surface coating and furnace lining and protective slag;Electrical industry, do electrodes, brushes, batteries, positive conductive materials, carbon tubes and so on;In the chemical industry, it is used as catalyst material for acid and alkali products and chemical fertilizer industry, as well as high temperature resistant and high pressure seals;In addition, it can also be used as lubricant, anticorrosive paint, pigment, pencil core, gunpowder, neutron reduction agent in atomic reactor and anti corrosion agent in aerospace industry
Q:Is the jade pressed by the machine natural?
The first is to make amorphous jade glass material. The reagent and reagent of sodium aluminum silicate and silicate containing colouring ions, formula according to jade composition content in a crucible into the mixing and grinding after the vessel, and then placed in a muffle furnace crucible is heated to 1100 degrees Celsius, and constant temperature cooling after a few hours, you will have to take the color of jade composition of amorphous glass material. The second is made of crystal jade glass. The amorphous glass will jade colored pieces to more than 125 meshes (i.e. particle size less than 0.125 mm), 600 kg / cm on the embedded prototype, heating prefabricated 14X15 (mm) cylinder or 14X6 (mm) of the wafer; then the preformed cylinder or wafer in high-purity graphite crucible. Bake in the oven at 140 degrees Celsius for 24 hours or more; and then the pressure chamber six crucible into a compressor, the compressor start six top closure, in the long time, current power, pressure relief, can get the crystal jade glass. Synthetic emerald glass by X ray powder diffraction analysis, infrared absorption spectrum analysis, chemical composition analysis, hardness measurement, relative density (specific gravity), determination of refractive index determination, fluorescence analysis, and the data are basically consistent with natural jade.
