Calcium chloride according to the content classification can be divided into anhydrous calcium chloride, liquid calcium chloride and calcium chloride dihydrate, according to the purpose classification can be divided into industrial grade calcium chloride and food grade calcium chloride. The details are as follows:
Magnesium chloride is a kind of chloride salt, according to the content can be divided into anhydrous magnesium chloride and magnesium chloride hexahydrate, including magnesium chloride hexahydrate according to the purpose of industrial grade magnesium chloride and food grade magnesium chloride, the chemical formula is MgCl2·6H2O. Food grade magnesium chloride, also known as hydrochlorite, appearance is colorless, transparent crystal.
Calcium chloride (CaCl2) is a common and more important chemical raw material in industry. It is divided into industrial grade calcium chloride and food grade calcium chloride according to its use, and into anhydrous calcium chloride, calcium chloride monohydrate (liquid calcium) and calcium chloride dihydrate according to its content.
In order to deeply study and implement the spirit of the 13th Party Congress and welcome the 20th victory of the Party, on the afternoon of August 26th, the Party branch of Beihua Real Estate Company and the Party branch of the Enterprise Reform Department of the municipal State-owned Assets Supervision and Administration Commission carried out the theme Party Day activities jointly built by pairs in the Cultural innovation Park of Beihua Tengyi Xin Hall. With the theme of "Learning and implementing the spirit of the 13th Municipal Party Congress, opening a new chapter of the utilization of stock assets", the joint construction aims to promote the effective implementation of key projects of the utilization of stock assets of Beijing Chemical Group based on the Party construction and the main business. Peng WangXIAN, SHAN Shiwei, Yang YI, QU HanQING, DEPUTY DIRECTOR of Enterprise Reform Department of Municipal State-owned Assets Supervision and Administration Commission, LI Yong, member of the Group Party Committee and assistant to the General manager, as well as more than 30 Party members from the Group's Real Estate and Resources Department, Beihua Real Estate, Huateng Development, Huateng DanBI, Huateng Dongguang and other departments and units attended this activity.
Magnesium oxide is a kind of ionic compounds, commonly known as magnesia, also called magnesia, chemical formula MgO style, magnesium oxide is a form of the existence of solid at room temperature, it is put to raw materials of magnesium, magnesium oxide the appearance of white powder, magnesium oxide according to use can be divided into light magnesium oxide and heavy magnesium oxide, heavy magnesia can be divided into using magnesia powder and magnesium oxide light burning powder, Magnesium oxide light burning powder is divided into magnesium oxide desulfurization powder and magnesium oxide building materials powder.
Flame retardant refers to the auxiliary agent that can make inflammable polymer refractory, mainly flame retardant for polymer materials. There are many kinds of flame retardants, according to the method of use can be divided into additive flame retardants and reactive flame retardants: additive flame retardants are added to the polymer by mechanical mixing flame retardants, mainly organic flame retardants, inorganic flame retardants and halogen flame retardants, non-halogen flame retardants; Reactive flame retardants are polymerized as monomers so that the polymer itself has a flame retardant component.
Our commonly used snow melting agent is mainly sodium chloride, calcium chloride, magnesium chloride and other chloride salts as the main component of inorganic snow melting agent, chlorine salt melting agent dissolved in snow, freezing point will fall below zero, the freezing point of salt water is lower than the freezing point of water, so it is difficult to form ice cubes after the salt dissolved in snow. After the melting agent is dissolved in water, the concentration of ions in the water rises, so that the liquid vapor pressure of the water drops, but the solid pressure of the ice is unchanged. In order to reach the state where the solid and liquid vapor pressure of the ice water mixture is equal, the ice melts.
