The development trend in Perlite At present, the annual output of expanded perlite in China has exceeded 4 million m3, accounting for about 5% of the annual output of insulation materials in China. It is the most widely used kind of light insulation materials in China. According to the statistics of relevant departments, at present, the application proportion of expanded perlite in the market in China is about 60% of construction projects, thermal pipe insulation is about 30%, and decorative materials are about 10%, so it is mainly used for building energy saving and equipment and pipeline insulation.
Although perlite is widely used in various fields, and is a popular industry, it has faced severe challenges in some fields, and in the near future, many materials will replace perlite. However, in order to meet the challenges of other products and materials, perlite and perlite processing industry should first reduce the production cost and improve the performance of products, and make full use of its own advantages to continuously develop new functional products, such as:
1, light waterproof heat insulation building materials products light quality, not easy to aging, waterproof heat insulation, suitable for high-rise buildings and light wall, pipe insulation, cold storage wall cooling, etc.
2, composite light functional plate products with light capacity weight, high strength, can be cut into different shapes suitable for the site needs, high surface smoothness after polishing treatment products.
3, glass building decorative board is characterized by excellent physical and chemical properties, luxurious texture, good decorative performance; its mechanical properties, climate resistance, gloss is superior to marble close to granite.
4. Soilless culture substrate is a very promising application field in agriculture, plants and horticulture. Some larger particles of perlite are gradually used in vegetable seedling raising, as an essential component of seedling soil, to increase the air permeability and water absorption of the nutrient matrix.
5, filter aid, practice shows that perlite and diatite, the effect is better than any kind of filter aid alone.
Therefore, with the continuous optimization of perlite products and the cost reduction to improve the performance, the use of perlite is still very extensive. Generally speaking, perlite is still very promising for development. If you want to continue to understand, you can pay attention to Zhengzhou Onuo Building Materials Co., LTD.
