Domestic situation
As China and the rest of the world pay more and more attention to building fire prevention, wood-based flammable organic sheets have been strictly restricted to construction projects, while inorganic gypsum boards such as gypsum board and calcium silicate board are used for strength, toughness and water resistance. The secondary processing performance can not meet the construction engineering and application requirements, resulting in a certain degree of resistance to promotion.
The fireproof board has the double advantages of the organic board and the inorganic board. It is a large-format sheet made of modified magnesite material as a binder and a medium alkali or alkali-resistant glass fiber cloth as a reinforcing material, mainly used for building cranes. Decoration of items, internal partitions and other parts with fire protection requirements. The sheet has both the lightness and flexibility of the wood-based organic board and the reworkability, as well as the fire resistance and water resistance of the inorganic sheet. Many large projects in China have used glass-magnesium fireproof panels in their renovation. After several years of application and practice, the use effect is good, and the amount of such plate exports is quite large.
Because the fireproof board is a new product, some construction and production personnel have not yet mastered the production technology and construction technology, and some enterprises are driven by economic interests, the production is shoddy, and the construction is sloppy. The user is indifferent to this kind of product, resulting in many accidents in the construction project, affecting the development of fireproof panels.
In the late 1980s and early 1990s, there was a boom in the production of fireproof panels in northern China, and production methods were mostly semi-manual and semi-machined. Due to the mastery of this technology at the end of the production plant, many inferior plates are flooding the market. These products are gradually exposed to many ills during storage and use, and the market is gradually shrinking.
Since the mid-1990s, the upsurge in the production of glass-magnesium fire-retardant panels has risen south of the Yangtze River in China, especially in Jiangsu, Shanghai, Guangdong, and Zhejiang. In some places, there has been a situation of rising. In some areas, there are more than a dozen production units in a town. The quality of products is inferior, dumping at low prices, and hitting the market, making it difficult for a few regular manufacturers to survive. This situation will not be reversed as soon as possible, and it will not be long before it will fall into a trough, and the market will soon be depressed, which is really worrying. People of insight who are engaged in this industry should be far-sighted because the development prospects of fireproof panels are very optimistic. With the increasing population in China and the world, construction projects will continue to increase, and the grades are getting higher and higher, and the corresponding demand for building fireproof decorative panels is increasing. The decorative plates on the market are basically divided into two categories. One is organic decorative plates based on wood or natural plant fibers. Due to the increasing fire protection requirements of buildings in China and the world, such plates are strictly restricted. In view of this situation, inorganic sheets have become the first choice, but other types of inorganic decorative sheets other than gypsum have few types and poor performance.
Building decoration works use the most used plasterboard. However, there are many shortcomings in the gypsum board: the strength is low, and the sharps appear in the hanging space; the toughness is poor, and the construction cannot be bent; it is not resistant to moisture and water. When the water meets the water, it will be deformed and softened, so there are few gypsum boards in the high temperature and high humidity areas in southern China. The fireproof decorative board has the dual advantages of organic decorative board and inorganic board. This product not only has the flexibility of organic sheet, can be reworked, but also has the fireproof and water resistance of inorganic board, and the strength is higher than any kind of decoration. Plate. Therefore, as long as the quality of the fireproof sheet is controlled, the product has a wide range of uses, good performance and great development potential. Some products of fire-resistant sheet metal factories in the south are exported to foreign countries. According to customs statistics, in recent years, the export of fire-retardant sheets has been exported for 1 billion yuan, and the consumption in China is also increasing year by year. This shows that the development prospects of this product are very optimistic.
Soluble fertilizer granular include calcium nitrate, Ammonium Sulphate steel grade and caprolactam grade, calcium magnesium nitrate, Potassium Sulphate. Monband granular fertilizer can add different color and trace elements.
Calcium Nitrate is a kind of green and natural fertilizer. It can improve the quality of soil, change the PH value, reduce the density of active aluminium and loose the soil. It can promote the root, stem, leaf to grow better.
Calcium Magnesium Nitrate is a high nutrition
