Salt is the common name for the compound, composed of crystalline mineral called rock salt or halite. Salt with a chemical name of Sodium Chloride and formula NaCl, belongs to the large class of salt. It is presented in huge quantities in seawater & it is the main mineral component of the sea. Sodium chloride is a mineral which plays a vital role for humans and animal health and therefore is used in several industries. By evaporating mineral rich seawater in the shallow pool and by processing it in the mines, various grades of salts are formed, further which can be processed. Salt is huge quantity is been used in production of other chemicals such as baking soda (sodium bicarbonate), caustic soda (sodium hydroxide), chlorine, hydrochloric acid and many more chemicals. It is used for several other industrial applications such as in manufacturing of paper pulp, polyvinyl chloride, plastics and in processes like de-icing highways, water conditioning and even for agricultural use. Salt is basic food items for humans too and plays essential role in human health as an electrolyte. We use it as an anti-caking agent and to prevent iodine deficiency.

Transformer Oils are electrical insulating oils produced by distillation of virgin paraffinic and naphthenic crude oils followed by modern technologies involving high pressure hydrogenation and hydro-treatment. All the processes are monitored closely and appropriate Base Oil fractions are selected for further processing. Further processing involves removal of moisture and polar impurities to obtain good electrical properties. The technologies result in products with very low pour point, excellent oxidation stability, cooling characteristics and electrical properties. These properties make them suitable for the most demanding transformer applications. Applications: The transformer oils are used in Distribution & Power Transformers, Switchgears and Circuit Breakers. Products Offered: Transol HGX is an inhibited grade of transformer oil specifically tailored for demanding applications in EHV and UHV Transformers. Transol GE IEC60296:2012 Uninhibited is an uninhibited oil which is designed to meet Specifications as per IEC 60296:2012.

Magnesium Oxide Board (or MgO Board) is a technologically advanced building material that offers superior performance in every category when compared to traditional wood, gypsum and cement based products. Magnesium Oxide Board is virtually impervious to fire, water, insects; does not feed mold or mildew; is non-toxic, non- flammable and non-combustible; is durable, maintains its dimensional stability-even when wet; and, has exceptional bonding surface. Magnesium Oxide Board is a mineral based green builder product. And it is homogeneous-no de-lamination. Features: WATER RESISTANCE Magnesium oxide inherently has very low water absorption and any moisture is naturally expelled. There is also no deterioration from freeze/thaw cycles. VERSATILITY Whether used on its own as a sheathing, wallboard or underlayment, or in conjunction with other building materials such as plywood, OSB or drywall, it can add tremendous value. MgO has an unlimited number of uses. Fire retardant plywood and OSB, demising walls and insulated exterior wall panels are some of the initial products that offer enormous performance-to-value propositions. FIRE RESISTANCE Magnesium oxide boards are essentially non combustible, with a flame spread of ZERO and a smoke development of ZERO.These properties make it highly effective either standing alone as a sheathing/underlayment or when laminated to other materials. IMPACT RESISTANCE While having the appearance and texture of cement or stone, magnesium oxide board has excellent flexure and tensile properties. All of these properties combine to produce a board with vastly superior impact resistance.

BRIEFING (October 21, 2020): Coke and Coal Analysis on Market and Trading Tips Keys Points: From Monday to Tuesday, price of domestic metallurgical coke and coking coal went up amid stabilities; that of PCI and thermal coal was stable; purchase price of PCI by steel mills went up and down. Met Coke: Several steel mills which priced in the second half of month in Southwest China accepted 50-yuan hike put forward by coking plants. Representative coking plants in Shanxi, Hebei and Shandong started the fifth round of price hike and requested a 50-yuan hike since October 20, to which steel mills did not respond yet. Coking plants had no inventory and that at ports was also declining, making it difficult for steel mills to replenish stock. Blast furnace operating rate of steel mills was high, indicating strong demand. Meanwhile, strict implementation of de-capacity in Shanxi boosted price as well. By the end of October, 5.6mn t of capacity was confirmed to be exited with newly added capacity of 750,000 t. 6.2mn t of capacity in Linfen, Yuncheng and Lvliang was asked to be diminished, which needed to follow up. It is expected that metallurgical coke price will stay at a high level for a short term. Table 1: Price of Domestic Standard I Grade Metcoke in Spot Market (yuan per ton) Coking Coal: Price of low-sulfur coking coal in Linfen, Shanxi rose by 20 yuan, and was stable at 1350-1370 yuan/t (bank acceptance); that of high-moisture coal increased by 20 yuan to 1360 yuan/t, total growth in September reaching 100 yuan. Price of raw coal went up by 20 yuan to 820 yuan/t, up 70 yuan in total. Quotation of imported coal kept falling; that of I grade coking coal dropped by $19.5 to $129-130 per ton in October; that of standard I grade coking coal declined by $2.5 to $119.5-122 per ton.

"Luxfine LCP leakage current prevention device" is a power supply device that prevents leakage current, and electrical devices used by receiving power through this device are safe from leakage current. Leakage current is the current generated by an electrical device outside the normal track, i) the current flowing between the applied live line and the ground, ii) the current flowing between the live line and the neutral line (N), e.g., between the two terminals of the outlet. When a person encounters a conductor of an electrical device, the leakage current flows through the human body and poses a serious threat to the body and life. "Luxfine LCP" allows the human body to safely use electricity by preventing current from flowing even when it encounters the conductor of an electrical device. It allows safe use of electricity even in humid places or when flooded. Existing short circuit breakers are designed to protect the system by operating at leakage currents above 30mA, but the risk of electric shock is always present in sections below 30mA where the short circuit breakers operate normally. In other words, the current between 6 and 30mA also has a significant effect on the body's muscular control and nervous system, leading to secondary accidents or death. Leakage current causes failure, malfunction, life span reduction, fire, etc. of not only the human body but also the electrical equipment used. To prepare for electrical hazards that may occur in the event of a malfunction of a short circuit breaker or in a section below 30mA that is not protected by a short circuit breaker, equipment that can fundamentally block leakage current was developed. The current between the conductor and the ground of the electrical device using this equipment is almost "Zero" amperes. "Luxfine LCP" has built-in functions to drastically reduce the generation of electromagnetic waves that are fatal to the human body and to pre-detect the risk of fire due to aging power lines or de-insulation. In addition, to single-phase 220V, three-phase 380V, products ranging from 300VA to 10kVA are developed as standard models. Commercial and industrial applications with much larger capacity, as well as products with a step-down function of input 220VAC and output 110VAC can be also customized. Applications Places that require a lot of moisture and water, sewage treatment plants, water purification plants, fish farms The expensive old equipment that needs to be overhauled due to leakage current Streetlight pole, signal light pole in areas vulnerable to electric shock or habitually flooded
