Vitrified micro bead is a new type of environmental friendly inorganic light thermal insulation material. In addition to its excellent properties of light weight, heat preservation, heat insulation and fire prevention, it also has the advantages of non combustion, high strength, low water absorption, good compatibility and long service life. The product is made of selected mineral sand with special particle size and expanded by electric furnace heating. By controlling the temperature and the blank time of raw materials, the surface of the product melts and the pores are closed. The product is irregular spherical particles with porous cavity structure inside. The surface is vitrified and sealed, with smooth luster and stable physical and chemical properties. The product can be used as a lightweight aggregate for new building materials industry; As a partial substitute for floating beads in light refractory industry; As a substitute of glass bead in emulsion explosive industry, it has broad application prospects and can be widely used in many fields such as industry, agriculture, building materials, chemical industry, smelting, light industry and so on.

The main raw materials of lightweight plastering gypsum mortar are gypsum and vitrified micro beads. Gypsum is an industrial by-product with a wide range of products and low price. Vitrified micro beads have the characteristics of light weight, fire prevention, heat preservation and sound insulation, and can be used as a good filling aggregate. Compared with the traditional cement mortar, the product has the advantages of more health and environmental protection, not easy to pulverize, not cracking and hollowing, not dropping powder and so on. It is easy to use and cost saving, and has a broad market.

Lightweight plastering gypsum is a kind of single component plastering leveling material, which is made of industrial by-product gypsum as cementing material, vitrified micro beads or expanded perlite as lightweight aggregate, and added with a variety of additives. It has the characteristics of early strength and quick hardening, good adhesion, light weight, micro expansion, etc. It can be used to replace the traditional cement mortar, solve the problems of hollowing and cracking on the wall, and improve the construction efficiency, At the same time, a large number of industrial by-product gypsum waste is absorbed!

Technical advantages and market prospect of light plastering gypsum products

1. The bond strength is 6 times of the traditional cement mortar, and the linear shrinkage rate is 1 / 10. Using it as the wall leveling material, the wall will not produce hollowing and cracking phenomenon, which solves the common problems of building quality in the building materials industry once and for all!

2. The thermal conductivity is 1 / 6 of cement mortar, and the plastering thickness of 15mm on both sides can meet the requirements of energy-saving design code in hot summer and cold winter area, and improve the energy-saving efficiency of residential buildings by 3-5%!

3. It is 50% lighter in volume and weight, which can not only reduce 80% of vehicle transportation volume, but also reduce 72 kg / m2 of building weight.

4. Can use machine spraying construction, the efficiency is three times of manual plastering, can greatly reduce the dependence on skilled plasterers, ease the labor problem!

5. Grade a fireproof material is an excellent fireproof material for steel structure;

6. It has the functions of humidity control, sound absorption and heat resistance, which can improve the living comfort. It is a wall that can breathe and a home that knows the cold and warm.

7. By using industrial waste residue as raw material, 70 million tons of by-product gypsum can be absorbed, and the utilization rate of by-product gypsum can be increased by 38%.

8. The material cost is equal, and it is economically feasible.

9. Market prospect

(1) As a new type of plastering material, lightweight plastering gypsum will eventually replace the traditional cement mortar, which can be seen from the dominant position of lightweight plastering gypsum in indoor wall leveling in developed countries. In France, Spain and Turkey, the proportion of light plastering gypsum is 90%, and the proportion of cement mortar is less than 10%; In the UK, light plastering gypsum accounts for 96%, gypsum board 3% and cement mortar 1%.

(2) In China, the wall leveling material is still traditional cement mortar, including commercial mortar produced in industry. According to the data of the National Bureau of statistics, in 2015, the newly-built housing area in China was 2 billion square meters. If light plastering gypsum is used as indoor plastering material, the demand is about 80 million tons, and the market prospect is broad.
