In recent years, China's grain dryer industry has delivered a stunning report card: From 2008 to 2010, the domestic dryer holdings increased rapidly at an average annual growth rate of around 50%. According to incomplete statistics, There are more than 500 domestic drying equipment manufacturers with annual sales of more than 3 billion yuan. Despite the rapid increase in domestic dry machinery holdings, mechanically dried grains account for only about 1% of the country's total grain output each year, while mechanical grain drying in developed countries in the world can reach about 90% of total production. The development of machinery can not be adapted to the needs of grain production development. With the development of deep processing of agricultural products, the increase of farmers' income, and the acceleration of the process of agricultural modernization, grain drying technology equipment will have a broad market prospect and huge potential for development. It is estimated that if the mechanical drying ratio reaches 30%, at least 8,000 to 10,000 sets of drying equipment are needed. In recent years, there has been a change in the relationship between grain purchase and sale systems and supply and demand. In addition to the promotion of mechanized harvesting operations, the number of high-moisture grain has increased, and some traditional non-high-moisture food production areas have also become high-moisture grain production areas. The grain moisture harvest in the high-moisture grain-producing areas has also increased, further expanding the demand for grain drying equipment. Hydroxypropyl methyl cellulose is a kind of non-ionic cellulose ether which is made from natural macromolecular material cellulose through a series of chemical processing. They are a white powder that swells into a clear or slightly turbid colloidal solution in cold water. It has the characteristics of thickening, adhesion, dispersion, emulsification, film forming, suspension, adsorption, gel, surface activity, water retention and colloid protection. Hydroxypropyl methyl cellulose and methyl cellulose can be used in building materials, coating industry, synthetic Resin, ceramic industry, medicine, textile, agriculture, daily chemical and other industries.
2. Improve the wet strength and the adhesion of the plate after extrusion.

Application field:
â—† Cement-based plastering
1. Improve the uniformity, make the plastering easier to apply, and improve the anti-sagging ability. Enhance mobility and pumpability to improve work efficiency.
2. With high water retention, it can prolong the working time of mortar, improve the working efficiency, and help the mortar to form high mechanical strength during the solidification period.
3. The air infiltration is controlled to eliminate the micro-cracks of the coating and form an ideal smooth surface.
â—† Light board
1. It enhances the machinability of the extruded lightweight board, and has adhesive strength and lubricity.
2. High water retention, extending the working time of mortar, and producing high mechanical strength during solidification.
3. By controlling the uniformity of mortar consistency, a high-quality surface coating is formed.
â—† Masonry mortar
1. Enhance the adhesion with the masonry surface, and can enhance the water retention, so that the strength of mortar can be improved.
2. Improve the lubricity and plasticity to improve the construction performance. The use of cellulose ether reinforced mortar is easier to use, save time, and improve cost efficiency.
3. The model with special high water retention is available for the bricks with high water absorption
â—† Plate joint filler
1. Excellent water retention, can prolong the cooling time and improve work efficiency. High lubricity makes application easier and smoother.
2. Improve the shrinkage resistance and cracking resistance, and improve the surface quality.
3. Provide a smooth and uniform texture, and make the bonding surface more adhesive.
â—† Tile adhesive
1. The dry mixing ingredients are easy to mix without agglomerates, thus saving working time. As the application is faster and more effective, it can improve the constructability and reduce the cost.
2. The tiling efficiency is improved by extending the cooling time. Achieve adhesion effect.
3. Special development models with high skid resistance are available.
â—† Water-based paint and paint remover
1. The storage life is extended by preventing solid precipitation. It is compatible with other components and has high biological stability.
2. It dissolves quickly without lumps, which helps to simplify the mixing process. The cold water dispersion model can make the mixing faster and more convenient,And it does not produce lumps.
3. It produces favorable flow characteristics, including low splashing and good leveling, which can ensure excellent surface finish and prevent paint sagging.
4. Enhance the viscosity of water-based paint remover and organic solvent paint remover, so that the paint remover will not flow out of the workpiece surface.
â—† Self-leveling floor materials
1. It provides viscosity and can be used as an anti-settlement agent.
2. Enhance mobility and pumpability, thus improving the efficiency of paving.
3. Control water retention to greatly reduce cracking and shrinkage.
