The aggregates for light plaster gypsum mainly include 50-70 mesh or 70-90 mesh, open or closed cell vitrified microspheres. Please call for inquiries if needed.

Boron nitride microspheres are an environmentally friendly new type of inorganic lightweight thermal insulation material. In addition to their excellent properties such as light weight, thermal insulation, fire resistance, and non-combustibility, they also boast high strength, low water absorption rate, good workability, and long service life. The product is made from selected mineral sand with special particle sizes, expanded under electric furnace heating. By controlling the temperature and the residence time of the raw materials, the surface of the product melts, the pores are sealed, forming irregular spherical particles with a porous cavity structure inside. The surface is vitrified and sealed, with a smooth, glossy appearance, and highly stable physical and chemical properties. This product can be used as a lightweight aggregate in the new building materials industry; as a partial substitute for expanded perlite in the lightweight refractory material industry; and as a substitute for glass microspheres in the emulsified explosive industry, offering a broad range of applications in various fields such as industry, agriculture, building materials, chemicals, smelting, and light industry.

Lightweight plastering gypsum mortar is primarily made from gypsum and vitrified microspheres. Gypsum is an industrial byproduct, known for its wide availability and low cost. Vitrified microspheres offer lightness, fire resistance, and thermal insulation, making them excellent as filling aggregates. Compared to traditional cement砂浆, this product is healthier, more environmentally friendly, less prone to dusting, non-cracking, and non-bulging, with ease of use and cost savings. The market potential is vast. Lightweight plastering gypsum is a one-component leveling material made from industrial byproduct gypsum as the binder, vitrified microspheres or expanded perlite as lightweight aggregates, and various additives. It features early strength, rapid hardening, good bonding power, lightness, and slight expansion, suitable for replacing traditional cement砂浆, addressing wall bulging and cracking issues, improving construction efficiency, and simultaneously absorbing large amounts of industrial byproduct gypsum waste!

Section II: Technical Advantages and Market Prospects of Lightweight Plaster Gypsum Products

1. The bonding strength is six times that of traditional cement mortar, with a linear shrinkage rate one-tenth of its value. Used as leveling material for walls, it eliminates the issues of hollowing and cracking, permanently solving the common quality problems in the construction materials industry! 2. The thermal conductivity is one-sixth of cement mortar. With a plaster thickness of 15mm on each side, it meets the energy-saving design specifications for hot summers and cold winters, improving the energy efficiency of residential buildings by 3-5%! 3. It is 50% lighter in volume, which can reduce the transportation volume of cars by 80% and the weight of the building by 72kg/m2. 4. It can be applied using machine spraying, which is three times more efficient than hand plastering, significantly reducing reliance on skilled plasterers and alleviating labor shortages! 5. It has an A-grade fire rating, making it an excellent fire-resistant material for steel structures. 6. It has functions such as humidity regulation, sound absorption, and heat resistance, enhancing the comfort of living spaces, making it a wall that breathes and a home that knows the seasons. 7. Made from industrial waste, it can absorb 70 million tons of by-product gypsum, increasing its utilization rate by 38%. 8. The material cost is comparable, making it economically feasible. 9. Market prospects
(1) As a new type of plastering material, lightweight plaster gypsum is set to replace traditional cement mortar. This can be seen from the dominant position of lightweight plaster gypsum in the leveling of interior walls in developed countries. In France, Spain, and Turkey, lightweight plaster gypsum accounts for 90% of the market share, with cement mortar at less than 10%; in the UK, lightweight plaster gypsum holds 96% of the market, gypsum boards at 3%, and cement mortar at 1%. (2) In China, the leveling material for walls remains traditional cement mortar, including commercial mortar produced industrially. According to National Bureau of Statistics data, in 2015, the total floor area of newly constructed buildings in China was 2 billion square meters. If lightweight plaster gypsum is used as interior plastering material, the demand would be approximately 80 million tons, indicating a vast market prospect.
