MH-300F graphite hydrometer brush electrodehydrometer MH-300F Hydrometer

Suitable for: graphite, carbon, refractory materials,conductive materials, corrosion resistant materialindustry, new materials research laboratory

Principle: according to ASTMD 854-02, JIS, GB/T, ISO standard. The Archimedean buoyancy principle, direct reading quantity accurate measuring value.

Technical data:

Carbon and graphite materials are non - metallicmaterials by solid carbon based carbon materials, whichbasically consists of non graphitic carbon materials,graphite material basically is composed of graphite carbon material, sometimes referred to as the carbon and graphite materials carbon materials.

Graphite is one of the crystallization of mineral carbon,color to black, crystal for six plate, usually in the form offlaky or scaly, aggregate is earthy, implicit amorphous body, soft, hardness is small, the Mohs hardness is 1-2,can pollute paper, the proportion of 2.1--2.3.

Graphite is the sharp rocks coke is the main raw material for electrode. There are 2 types of Carboniferouspetroleum system, selection and quality of raw materials,is very important. Purchase of sharp rocks, according to the types of grinding particle size of coke, the screenclassification. With the normal container storage graphitehas good chemical stability, acid and alkali resistance,corrosion resistance to organic solvent, but the high temperature oxidation.

Graphite electrode is porous absorbent products, strong water absorption, large porosity. Its appearance density is about 1.58~1.70, the porosity ranging from about 20~29%. In order to measure firing densification,electrode impregnation groove in the firing electrode is impregnated with asphalt. Results the densification is to improve the strength of electrode, electrical resistancecharacteristics.

Production of graphite carbon electrode, there are the following kinds of demand for density measurement: A,bulk density, dry density of B C, wet density method.
