Based on the disadvantage of traditional gap surge protector (spd), and combined with the material characteristics of graphite and thompson gas discharge theory, a large scale of experiments on the new type of graphite gap spd were completed by open circuit voltage wave generator and icgs impact system. The results show that, after the high voltage trigger capacitance device was added to the new type of graphite gap spd, every gap was triggered step by step so that the voltage protection level was reduced. At the same time, the graphite gap spd is better than traditional gap spd on time delay characteristics, and is able to achieve the arc extinction requirements before the power frequency voltage dropped to zero. In addition, graphite belongs to non-metal materials; it won't produce plasma under high temperature, which can improve the stability of device and delay aging.

We offer a wide plethora of Zinc in many forms including LME registered

dust, foil, granules, powder, pieces, anodize activated powder, shot,
and a mossy form.
Zinc is a bluish-white, lustrous metal. It is brittle at ambient temperatures but is
malleable at 100 to 150°C. It is a reasonable conductor of electricity, and burns in air
at high red heat with evolution of white clouds of the oxide. Plating thin layers of zinc
on to iron or steel is known as galvanizing and helps to protect the iron from corrosion.

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

Olive oil is the oil that comes from the fruit of the olive tree (Olea europea). Virgin olive oil is produced by mechanical processing of the olive fruit in olive mills. It is a key element of the Mediterranean diet and is considered a healthy food product due to its content of monounsaturated fats, antioxidants, etc.
Physical and chemical characteristics
Crude virgin olive oil is a mixture of various ingredients. These can be distinguished into three categories: Glycerides, fat-soluble substances and water-soluble substances. They can also be distinguished into saponifiable and non-saponifiable components. Glycerides, which are also saponifiable components, are mainly triglycerides, i.e. esters of glycerol with fatty acids. The latter are mainly: oleic, palmitoleic, linoleic, stearic and palmitic. The first three are unsaturated fatty acids, and the other two are saturated
Historical data
In the Greek area, presses for the production of oil from olives and containers (jars) for oil storage dating from the Mycenaean era have been found. According to the excavations carried out in the Proto-Cycladic II (2,700-2,300 BC) cemetery of Spedos in 1903 by Klonos Stefanos, among the other finds, he mentions a silver-plated clay vessel which contained traces of spoiled olive oil. The careful research in the chemistry of the National University under Professor K. Zengeli proved, beyond doubt, the existence of olive oil. Klonos Stefanos (in the Proceedings of the Archaeological Society PAE 1906) notes that together with the silver-plated clay vessel, a triple clay oil lamp was found. Olive oil is referred to on a Linear B tablet from Knossos as erawo (oil) and on others with a special ideogram.
Olive oil and health
Olive oil contains high levels of monounsaturated fatty acids (MUFA) as well as an abundance of bioactive components. Of these, the phenolic components are the most extensively studied. Regarding the benefits of MUFAs in human health, the US Food and Drink Administration authorized qualitative health claims (health claims), for the first time in 2004, regarding the protection offered by monounsaturated fatty acids of olive oil against cardiovascular risk diseases. Overall, the benefits of olive oil fatty acids were summarized at the first International Conference on Olive Oil and Health, in 2005. But olive oil is more than a rich source of monounsaturated fatty acids. Its phenolic components have shown anti-inflammatory and chemo-protective properties. Oleocanthal in olive oil has been found to have a similar effect to the anti-inflammatory drug ibuprofen. In none of the studies in which the role of phenolic components of olive oil has been examined, cytotoxicity has been shown.

Method of production

Nitrocellulose is a mixture of acid that nitrates cellulose, undergoes acid removal, pre washing, boiling, washing, dehydration, and then uses alcohol to remove water, resulting in nitrocellulose containing alcohol.

purpose

Nitrocellulose is mainly used in the plastic industry to manufacture stationery and educational items such as table tennis balls, triangular plates, pen holders, eyeglass frames, toys, and umbrella handles and tool handles in daily necessities. Nitrocellulose can also be used as a fiber, adhesive, coating, and substrate material.
