Changsha put into production the largest chemical equipment production base in central China

Changsha Weigh Chemical Machinery Co., Ltd. was established and put into operation at the National Changsha Economic and Technological Development Zone (located in Xingsha) on the 26th. This is the largest local chemical production equipment production base in the central region so far.
Weizhong Chemical was transformed from the former Changsha Chemical Machinery Plant in 2003 by Wasion Instrument Group and mainly provided equipment for the chemical, building materials, pharmaceutical, environmental protection and municipal industries. In the past three years, through the cooperation of production, teaching and research, the company has independently developed domestic original technologies such as integrated clamped high-pressure vessels. A group of new processes, new technologies and new products have reached international and domestic leading levels, and sales revenue has grown by more than 40% every year. The basic monopoly of domestic large-diameter high-pressure container market, some products are exported to the United States, Southeast Asia and Africa.
It is reported that the company is currently building a full-scale construction of 352 acres of Weizhong Industrial Park, which will be constructed in two phases. The first-phase project will invest 150 million yuan to build a high-standard industrial plant of 30,000 square meters. The person in charge of the company stated that by the end of the “Eleventh Five-Year Plan” period, the company will build a domestic first-class heavy chemical machinery manufacturing center and achieve an annual output value of over one billion yuan.

ACID

Acids exist universally in our life. There are both numerous kinds of natural acid compounds with biological functions and massive synthesized acids which are used in many ways.

In industry

Acids are fundamental reagents in treating almost all processes in today's industry. In the chemical industry, acids react in neutralization reactions to produce salts. For example, nitric acid reacts with ammonia to produce ammonium nitrate, a fertilizer. Additionally, carboxylic acids can be esterified with alcohols, to produce esters. Acids are often used to remove rust and other corrosion from metals in a process known as pickling. They may be used as an electrolyte in a wet cell battery, such as sulfuric acid in a car battery.

In food

Many acids can be found in various kinds of food as additives, as they alter their taste and serve as preservatives. Phosphoric acid, for example, is a component of cola drinks. Acetic acid is used in day-to-day life as vinegar. Citric Acid is used as a preservative in sauces and pickles. Certain acids are used as drugs. Acetylsalicylic acid (Aspirin) is used as a pain killer and for bringing down fevers.

Acid catalysis

Acids are used as catalysts in industrial and organic chemistry; for example, sulfuric acid is used in very large quantities in the alkylation process to produce gasoline. Some acids, such as sulfuric, phosphoric, and hydrochloric acids, also effect dehydration and condensation reactions. In biochemistry, many enzymes employ acid catalysis.
