1. Product Introduction
The graphite digestion system is an instrument used for sample pretreatment in chemical analysis. It is mainly used to dissolve organic and inorganic substances in solid samples into solutions for subsequent analysis and measurement. It heats the sample in a surrounding heating method, effectively increasing the utilization rate of thermal energy. At the same time, it occupies the front end of conventional digestion equipment with its advantages of higher temperature control accuracy, small differences between holes, fast digestion, energy saving and environmental protection. It can adapt to various types of samples, including soil, water, plants, food, etc. Graphite digesters are widely used in environmental monitoring, food safety, geological exploration and other fields. It can process samples quickly and efficiently and provide accurate and reliable analysis results.

IV. Advantages of our graphite digester
Advantage 1: High temperature resistance, acid and alkali resistance and organic solvent corrosion resistance, good stability;
Advantage 2: Fast sample digestion speed, batch processing of samples;
Advantage 3: Fully enclosed design, while preventing heat loss to a large extent, can also effectively avoid acid mist invasion and damage to equipment components;
Advantage 4: Clean and corrosion-resistant: Using a special spraying process, the coating is uniform, firm, and will not fall off after long-term use;
Advantage 5: Using advanced integrated surround heating method, all parts of the sample are heated evenly, and the digestion is fast and complete;
Advantage 6: Easy to operate, environmentally friendly and energy-saving, saving economic costs;
Advantage 7: PID temperature control system, excellent performance, high temperature control accuracy, up to �±1â??.
Advantage 8: The heating rate can be adjusted to achieve program heating and control the heating holding time, and the heating rate is stable;
We advocate stable, healthy and fast experiments!

The chemical properties of graphite are very stable, high temperature resistance, corrosion resistance, and good conductivity.Therefore, graphite can be used as refractory material, sealing material, conductive material, and is widely used in high temperature metallurgy, sand finding, paint lubricant, pencil lead, pigment, polishing agent, petrochemical industry, synthetic fiber, heater and other industries.
Natural graphite
UHP 400mm*1800mm UHP 450mm*1800mm Used in steel, cement and glass manufacturing, expanded graphite - based sealing gaskets, graphite grease, braid, brushes, brake lining, etc.
Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills. It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color. Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating. From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list In particular the mill scale can be classified as follows: Einecs (european commission no.): 266-007-8 Waste code: 10 02 10 Basel code: b 12 30 Hs code: 2619.00
We are glad to propose 500 MT of stain less steel mill scale. Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products. At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel. The recovery ratio after melting in furnace for the most valuable alloy elements is: - Ni: 3.5 - 4.5% - Cr: 6-8% From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows: Waste code: 10 02 10 The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers. Chemical analysis of the material is available on request.
