　　As China and other countries in the world are paying more and more attention to building fire protection,wood-based combustible organic boards have been strictly restricted to construction projects,while inorganic fire-resistant boards such as paper-faced gypsum board and calcium silicate board have strength,toughness and water resistance.1.The secondary processing performance can not meet the construction and application requirements of the construction project,resulting in a certain resistance to promotion.

　　Fireproof board has the double advantages of organic board and inorganic board.It is a large-format thin board made of modified magnesite material as a binder and medium-alkali or alkali-resistant glass fiber cloth as a reinforcing material.It is mainly used for building cranes.Items,interior partitions and other parts with fire protection requirements.This kind of board not only has the lightness,flexibility and reprocessing performance of woody organic board,but also has the fireproof performance and water resistance performance of inorganic board.Many major projects in China have used glass-magnesium fire-retardant plates in the decoration.After several years of application and practice,it has proved that the use effect is good,and the export volume of this plate 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,and the production is rough and indiscriminate during production.Users are inseparable from this product,resulting in many accidents in construction projects,affecting the development of fire-resistant panels.

　　In the late 1980s and early 1990s,there was a boom in the production of fire-resistant panels in northern China.The production methods are mostly semi-manual and semi-mechanical.The fact that the production plant has mastered this technology has caused many inferior plates to flood the market.These products gradually exposed many ills during storage and use,and the market gradually shrank.

　　From the mid-1990s to the south of the Yangtze River in China,there has been an upsurge in the production of glass magnesium fireproof plates,especially in Jiangsu,Shanghai,Guangdong,and Zhejiang.In some places,there is a coup situation.In some areas,there are more than a dozen production units in a town.The product quality is poor,dumping at a low price,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.The market will soon be depressed,which is really worrying.People of insight in this industry should have a long-term vision,because the prospects for the development of fire-resistant panels are very optimistic.With the gradual increase in population in China and the world,construction projects will continue to increase,and the grade is getting higher and higher,and the corresponding demand for building fireproof decorative plates is increasing.The decorative boards on the market are basically divided into two categories.One is organic decorative boards based on wood or natural plant fibers.As China and other countries in the world are increasingly demanding building fire protection,this type of board is strictly restricted.In view of this situation,inorganic boards have become the first choice,but there are few types of inorganic decorative boards other than gypsum and poor performance.

　　Building decoration works use paper gypsum board at most.However,there are many shortcomings of paper-faced gypsum board:low strength,holes in sharp objects in the hanging space;poor toughness,can not be bent construction;not resistant to moisture and water.It deforms and softens when it meets water and tide,so gypsum board is rarely used in high-temperature and high-humid areas in southern China.The fireproof decorative sheet has the dual advantages of organic decorative sheet and inorganic sheet.This product has the flexibility and reworkability of organic sheet,as well as the fireproof and water resistance of inorganic sheet,and its strength is higher than any kind of decoration.Plate.Therefore,as long as the quality of the fireproof board is well controlled,this product has a wide range of uses,good performance and great potential for development.The products of some fireproof board factories in the South are exported to foreign countries.According to customs statistics,the annual export of fireproof board has been spinning for 1 billion yuan,and the consumption in China is also increasing year by year,which shows that the development prospect of this product is very optimistic.
