Q:What are the characteristics of jade? There are jade and jade on the market. How do you distinguish it from jade?
Artificial jade, like artificial diamond, is a kind of natural gem product made by artificial simulation of natural gem. It has certain characteristics of natural gem. Emerald is based on the super bedrock rock are widely distributed, actinolite glaucophane schist and chlorite schist, high temperature and ultra high pressure on the geological environment in the formation of the process of imitation jade.
Q:Can industrial induction furnaces heat graphite?
However, it can heat something else and then heat the graphite by heat transfer.
Q:Is the silicon carbide crucible good for use? What's the difference between an ordinary graphite crucible and a graphite crucible?
The crucible can be placed on the iron tripod with either positive or oblique directions, and can be placed on the basis of the requirements of the experiment. When the crucible is heated, it cannot be immediately placed on a cold metal table to prevent it from breaking due to rapid cooling. It should not be placed on the wooden table immediately so as not to spoil the table or cause fire. The correct method is to cool the metal on the tripod or to let it cool slowly on the asbestos net. For crucible purposes, see the crucible tongs. The relevant information from the supply of silicon carbide crucible dachengxian Tianjin high silicon carbide crucible crucible factory released using the latest international technology of isostatic pressing method and strict quality assurance inspection system, using advanced refractory raw materials, high-tech formula developed a new generation of high-quality silicon carbide crucible, this product has a large volume density, high temperature resistant, fast heat, acid and alkali resistance, high temperature strength, oxidation resistance and high service life is 3 times that of the clay graphite crucible.
Q:What are the two methods of atomization? What orders of magnitude can be measured?
The sharp line spectrum of the A light source as the light source for analyte emission of sufficient strength, tellurium, atomic system. Quartz furnace atomic system is the gaseous analytes a method of introducing quartz furnace atomic intrinsic low temperature: electrodeless discharge lamp B atomizer without hollow cathode lamp (atomizer) can be divided into pre mixed flame atomizer (premixed flame atomizer), small, amplifier, ashing and background stability generally used; the level of mL, 10-9g/ were detected by flame atomic absorption spectrometry. The hydride generator can be used for 8 kinds of volatile element mercury. The atomic absorption spectrometer consists of an atomic absorption spectrometer that consists of a light source: an atomizer
Q:Use the tripod why use mud, and mud and three foot tripod supporting in the use of the crucible?
Otherwise, the three foot above the ring hole is too large, directly on the crucible to fall down.
Q:Is the heat conductivity of the crucible good for graphite or iron?
Purely from thermal conductivity, it must be graphite good. Graphite crucible in addition to resistance to fall, short life, all the performance is good.
Q:What is the use of graphite for corrosion resistance?
The corrosion resistance of graphite with good thermal conductivity, low permeability, can be used for the production of heat exchanger, reactor, condenser, combustion tower, absorption tower, cooler, heater, filter and pump equipment.
Q:The use of earthy graphite?
Wear resistant materials: graphite is often used as a lubricant in the mechanical industry. Lubricants can not be used in high speed, high temperature, high pressure conditions, and graphite wear-resistant materials can be at 200~2000 degrees Celsius temperature in a high sliding speed, without lubricating oil work. 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.
Q:Can the silicon carbide bearing in the canned motor pump be replaced by graphite bearing? How big is the difference?
Yes, our canned pump uses graphite bearings.
Q:Melting the iron in the graphite crucible. Does the graphite in the crucible turn into carbon and it melts into the steel?
In addition to carbon, charcoal contains hydrogen, oxygen, nitrogen, and a small amount of other elements. Carbon in charcoal is not a transition crystal like graphite, but amorphous carbon and no C-C covalent bonds. Charcoal ignition is 320-370 DEG C, the general fire than the high temperature, so the charcoal can be lit.
