Development Expectation of Magnesium Hydroxide Industry

Development Expectation of Magnesium Hydroxide Industry

Magnesium oxide industry is one of the domestic traditional chemical advantage industries, in recent years, magnesium hydroxide industry based on the advantages of technological upgrading, ushered in steady development. In recent years, the magnesium oxide industry has been committed to extending the industrial chain and focusing on improving the added value of products. With the expansion of the scale of the magnesium oxide industry, the downstream industrial chain is gradually stretched and widened, and the development of the chemical industry based on magnesium oxide is becoming more and more perfect. The downstream product market has a certain scale.

Magnesium hydroxide market season is coming

Magnesium hydroxide market season is coming

As the peak season of magnesium hydroxide market demand is approaching, under the stimulation of recent price increases in foreign markets, China's magnesium oxide enterprises have announced price increases. Since the fourth quarter of 2018, the domestic magnesium oxide market has entered the off-season of demand, and the price is relatively low. At the same time, due to the impact of winter production restrictions, the operating rate of magnesium oxide enterprises has declined, and the industry has shown a trend of destocking. As a result, manufacturers' inventories are generally low and orders are full, and large enterprises are the first to announce price increases for domestic customers.

Do you know the application of aluminum hydroxide in waste incineration

Do you know the application of aluminum hydroxide in waste incineration

Waste incineration treatment is often seen in our lives, waste incineration will emit two types of harmful substances and heavy metals. The quality of waste incineration directly affects our health. But did you know that aluminum hydroxide is also used in waste incineration? Calcined aluminum hydroxide can produce activated alumina, which is widely used as an adsorbent and catalyst carrier, and has the effects of promoting combustion, adsorbing two types of harmful substances, and inhibiting the dissolution of heavy metals in landfill incineration ashes. When the incinerator is operated in the range of 800~1000 ℃, the aluminum hydroxide becomes activated alumina. The specific surface area of activated alumina is

What are the chemical properties of magnesium hydroxide?

What are the chemical properties of magnesium hydroxide?

The chemical properties of magnesium hydroxide are: white crystals or powder. The aqueous solution is alkaline. 2.36g/cm3. Soluble in dilute acid and ammonium salt solution, basically insoluble in water and alcohol. The solubility in water (18°C) is 0.0009g/100g. Easy to absorb carbon dioxide in the air. When heated to above 200 ° C in an alkaline solution, it becomes a hexagonal crystal system. Decomposition at 350°C to form magnesium oxide and water. Above 500 ℃, the loss of water is transformed into magnesium oxide. Magnesium carbonate in boiling water can be converted into magnesium hydroxide, which is less soluble. Magnesium hydroxide is commonly used in PE,PP,PVC,ABS,PS,H

Analysis of the Advantages and Disadvantages of Four Different Cable Flame Retardants

Analysis of the Advantages and Disadvantages of Four Different Cable Flame Retardants

The advantages and disadvantages of the four commonly used cable flame retardants are compared. We can learn more about them. Antimony flame retardant advantages: antimony trioxide can not be used as a flame retardant alone, but can be used in combination with appropriate halogen compounds to play a particularly effective flame retardant performance. Antimony flame retardant synergistic organic mechanism. Disadvantages: heavy metals, toxic, and arsenic homologs, crude products generally contain arsenic and other heavy metals, arsenic trioxide is arsenic. Can not be used as green filler and green flame retardant. 2 Aluminum hydroxide flame retardant advantages: low price, good flame retardancy. Disadvantages: poor heat resistance, dehydration starts at 200 ℃

Introduction of various types of flame retardants and comparative analysis of their advantages and disadvantages

Introduction of various types of flame retardants and comparative analysis of their advantages and disadvantages

In recent years, with the increase in the output of plastic products and the improvement of safety standards, flame retardants have become more widely used. Generally speaking, flame retardant materials can be divided into organic flame retardant materials and inorganic flame retardant materials. Among them, organic flame retardant materials are mainly halogen additives, and inorganic materials not only have a certain flame retardant effect, but also produce hydrogen chloride and prevent smoke. In addition, inorganic flame retardant materials are non-toxic, non-corrosive and inexpensive. The consumption of inorganic flame retardant materials in the United States, Japan and other countries exceeds 60%, however, the consumption of inorganic flame retardant materials in China is less than 10%. ① halogen flame retardant halogen flame retardant not only the largest output, but also

Why flame retardant modification is so complex

Why flame retardant modification is so complex

Recently, Xiaobian often encounter similar problems, today we come to popularize: first, the combustion process of complex combustion has three conditions: combustible, combustion, to reach the ignition point. Because combustibles have a variety of phases (gaseous, liquid, solid, liquid has different vapor pressures, solid has tight and loose points), the concentration and diffusion of combustion improvers exist, and the ignition point exists high and low, so the combustion process is very complicated. This involves open burning and smoldering. In addition, the spread of fire is also part of the content of combustion. Therefore, there are also many combustion test modes, such as vertical combustion, horizontal combustion, glow wire

Do you know the use of wood flame retardants?

Do you know the use of wood flame retardants?

Wood flame retardant is a new type of halogen-free environmentally friendly liquid flame retardant. This product has changed many shortcomings of traditional flame retardants, which are easy to return to moisture and low flame retardant grade. It is an environmentally friendly flame retardant with excellent performance in the world. Dedicated to wood (multilayer board, furniture, floor), insulation board and other industries. Advantages: 1. low smoke, smoke suppression; smoke toxicity than traditional flame retardants greatly reduced. 2. High efficiency: Due to its good permeability, it can achieve obvious flame retardant effect in a short time. 3. Halogen-free, non-toxic, in line with international environmental requirements. 4. Flame retardant grade: can reach B1 flame retardant grade, such as: wood oxygen index can reach 80%,
