Vietnam's economy has developed rapidly in the past few years, and its speed has entered the top ten in the world. Infrastructure projects such as real estate, public transport and civil facilities have been increasing. A new upsurge has also emerged in the construction of residential buildings, new urban areas, industrial zones and economic development zones. As Vietnam's industrial base is weak, investment funds of local enterprises are weak, production technology is backward, research and development capacity of new products is insufficient, price competitiveness is weak, so far Vietnam's building materials machinery market mostly needs to rely on imports. China is Vietnam's largest import market, accounting for 80.8% of the country's total imports. Since China's "one belt and one road" initiative has been in line with Vietnam's "two corridors and one circle" plan, trade cooperation between the two countries has been continuously strengthened, and this year is expected to exceed 100...

Foam concrete block is foamed by the foaming machine. The foam agent is fully foamed by mechanical way , and the bubles mixed with cement evenly, then injected into the mold, forming a new lightweight thermal insulation material which contains a large number of closed pores. It is a bubble like insulation material, which is characterized by the formation of closed foam holes so that the foam concrete blocks are lightweight and heat-insulation. Main raw materials: cement, fly ash, fiber, foam agent, and additives. These raw materials are mainly inorganic. There are no harmful substances and no odor. No decomposition in the application process, which is green and environmentally. The foaming agent is neutral and without harmful substances such as benzene and formaldehyde, it avoid environmental pollution and potential fire hazards. It is the best choice for the insulation building. The process of production Material weighing - material mixing (adding foam agent, additives, etc.) - materi...

Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral and a commercial product useful for its light weight after processing. Perlite is widly used to produce light weight wall panel due to its light weight feature. More and more wall panel facotry will adopt perlite for their final finished wall panel products. It is very necessary study perlite in more details. Perlite boulders with fireweed in foreground. Perlite softens when it reaches temperatures of 850–900 °C (1560-1650 °F). Water trapped in the structure of the material vaporises and escapes, and this causes the expansion of the material to 7–16 times its original volume. The expanded material is a brilliant white, due to the reflectivity of the trapped bubbles. Unexpanded ("raw") perlite has a bulk density around 1100 kg/m3 (1.1...
