The development prospects of gypsum block
Qingdao gypsum processing and specialequipment of small make up to tell you the development prospects of gypsum block
In the 1940 s, the world started to use natural gypsum of half water gypsum as raw materials, production of gypsum block with flat die casting method. In the mid - 1950 - s, convert the model casting, jack-up technique, yields have increased significantly.
Since the 1970 s, constantly improve the molding technology, the model jackup technique development from semiautomatic to fully automatic. With hydraulic automatic knife form, for example, tonguegroove, alloy mold chrome plated surface significantly improve product quality, a multimode cavity mould individual output increase, with pneumatic telescopic fixture positioning clamping right, lift and move the entire block.
Since the 1990 s, with the flue gas desulfurization gypsum instead of natural gypsum as raw materials, and constantly improve the quality of products.
More than 60 countries around the world production and use of gypsum block, is mainly used for residential, office buildings, hotels, etc as nonbearing wall.
International has been recognized as gypsum block is the sustainable development of green building materials products, accounted for over 30% of the inner wall of the total amount in Europe. Production and use of gypsum block of European countries have Russia (100 million ㎡ / a), France (25 million ㎡ / a), Germany (8 million ㎡ / a), Belgium (4.5 million ㎡ / a), Spain (4 million ㎡ / a), Poland (4 million ㎡ / a), Italy, Austria, Switzerland, Luxembourg, Greece, Turkey, Finland, the Czech republic, Romania, Bulgaria, Serbia, etc.
