development and market trend of hydroxypropyl methylcellulose
Hydroxypropyl methylcellulose is a leading sub-sector in the fine chemical fiber industry. If it is deeply connected to downstream demand, there will be much room for development in the future. In order to break through the application bottleneck, the hydroxypropyl methylcellulose industry, trying to meet the high-end and emerging demand, is just a breakthrough in the further development of the hpmc
At present, cement mortar, tile cement, asbestos and other refractory coatings, gypsum coagulation slurry, joint cement, latex putty, latex, electronic materials, refractory mortar, water-based ink and many other industries are immeasurable. The role. The demand for building materials is the largest. In the development of the building materials industry in 2015, the development of the land market has the greatest impact on the supply and demand of hydroxypropyl methylcellulose, and it is also directly related to its price trend.
plays an important role in many fields such as defense industry, medical and health, building materials, information industry, energy conservation and environmental protection. In 2017, China's hydroxypropyl methylcellulose production increased by 10.3% over the previous year; consumption increased by 13%; this shows that there is still a large gap in demand, especially for high-end products. In order to fill this gap, it is necessary to improve the production process. At present, it is mainly accomplished by three reactions such as lint treatment, hydroxypropylation and methylation. The various technologies that have emerged in recent years have only focused on improving and improving the operation of individual units. Generally, cotton wool is used as a raw material, and alkaline treatment is carried out with a 50% aqueous sodium hydroxide solution to obtain a cellulose sodium salt, which is subjected to hydroxypropylation and methylation. So to meet the emerging needs and high-end product levels, it is necessary to continuously improve the production technology to develop new technologies, improve the viscosity of hydroxypropyl methylcellulose and increase the fineness, breaking through the current market standard of 80 to 120, I believe that hydroxypropyl Methylcellulose has a lot of room for development.
