Foam glass or thermal insulation material market "dark horse"

Foam glass uses waste glass as the main raw material, and is added with foaming agent, modifier, accelerating agent, etc., finely crushed and evenly mixed into batch materials, placed in a specific mold, and melted and heated in a heating furnace through 750-900°C. Foaming, annealing creates a porous glass material filled with numerous uniform bubbles inside. The bubbles in the glass account for 80-95% of the total volume, the diameter of the bubbles is about 0.5-2mm, and the density is 180-350kg/m3, which is only about one-tenth of ordinary glass.

Foam glass has such physical properties as low density, high strength, and low thermal conductivity, as well as functions such as heat preservation, heat insulation, sound absorption, moisture proof, waterproof, and fire prevention. Foam glass has been widely used in foreign countries. Compared with other building materials, foamed glass material overcomes various defects such as perlite, light calcium carbonate, foamed plastic, and cork, and has a comparative advantage in terms of cost performance. Great advantage. Foam glass has a series of superior performances such as thermal insulation, waterproof, moisture-proof, fireproof, acid and alkali resistance, low density, and high mechanical strength. It has the inherent advantages of permanent, safety, reliability, chemical resistance, and resistance to anthill intrinsic to the glass material itself. It can be applied to the thermal insulation, thermal insulation, waterproof and moisture-proof engineering of the interior and exterior walls of buildings. Decoration engineering, petrochemicals, refrigeration, subway and underground engineering and other fields.

Foam glass is a new type of high-quality inorganic rigid insulation material, and it is also an energy-efficient building material. It uses waste glass to reduce environmental pollution and increase resource utilization. Mainly used for cold storage, underground oil pipelines and building walls and roofs, its good thermal insulation effect. The raw materials for the production of foam glass are low in price and rich in resources. The current demand for such new materials in construction projects is very urgent, and its development and application prospects are broad.

The prospect of thermal insulating wall materials is boundless. By the end of 2000, China's Ministry of Construction had decided to achieve the 50% target for building energy efficiency. This means that the building energy-saving materials market will require a large number of products with excellent mechanical properties, significant energy saving effects, and low prices in the coming years. The primary task of building energy conservation is to save energy in the wall. Therefore, improving the thermal insulation performance of the building wall is the key to reducing building energy consumption. At present, China is actively developing and producing wall thermal insulation materials so that it can increase the wall thermal resistance and reduce the wall heat transfer coefficient. Insulating wall materials should have better development prospects in the future market. According to statistics, by the end of 2000, China's urban residential, public and productive buildings will require approximately 2.87 billion square meters of insulation and thermal insulation materials, and potential market for insulating wall materials. Great.

The building materials products that China will give priority to during the fifteenth period include: new wall materials (clay hollow products, beneficial waste products and non-clay products) and new insulation materials. At present, the foam glass has been listed in the national key promotion and development of new building materials directory. Foam glass building insulation materials have been incorporated into the standard atlas of the building's roof surface and exterior wall thermal insulation building, laying the foundation for the application of foam glass in the field of building insulation energy-saving.

In the Ninth Five-Year Plan for the National Economic and Social Development and the 2010 Vision Outline, China has listed the construction and building materials industries as the country's pillar industries. During the period of the Ninth Five-Year Plan period, the construction area of ​​residential buildings for urban residents in China, together with other public buildings, will reach an area of ​​more than 5 billion square meters. This large-scale housing construction, wall materials account for about 70% of the building materials, and its Demand can be imagined. In 2000, the state demanded that the output of new wall materials account for 40% of the total demand of the wall. If it is still calculated according to the total building area of ​​5 billion square meters during the period of the Ninth Five-Year Plan, it will reach 2 billion square meters, if 1% of the glass is used, Will require 1 million cubic meters of foam glass. As a new type of low-cost green energy-saving environmental protection products, foam glass will certainly play an important role in the development of new wall materials in China. In April 2000, the project was reported in a "Approach to Science" section of the central government.

According to statistics, China's building energy consumption accounts for 23.1% of the total energy consumption, while the annual heating and cooling energy consumption of various types of buildings account for about 10% of the total national energy consumption. It is necessary to develop and produce energy-efficient building insulation materials such as foamed glass. It can turn waste into treasure, reduce pollution and benefit the environment. Rich sources of raw materials, simple production technology and equipment, low investment, low cost, convenient construction, thermal insulation and environmental protection in one, is a promising new type of insulation and energy-saving materials, suitable for glass factories and various building materials companies to produce.
