Background
Calcium sulfate whisker, another name: the gypsum whisker and the gypsum fiber have wide application, can be used as paper making raw materials, as reinforcing components of plastics, rubber, polyurethane, metal and ceramics, as a substitute of asbestos serving as a friction material, can be used in the aspect of environmental engineering, and can be used for filtering materials to remove harmful impurities in waste gas and waste water.
At present, the production of calcium sulfate whiskers industrialized at home and abroad mainly takes natural gypsum as a raw material, and two methods, namely a hydrothermal method and a normal-pressure acidification method, are mainly adopted: the hydrothermal method is to add dihydrate gypsum suspension with the mass fraction of less than 5 percent into a high-temperature pressure-resistant container for treatment, the dihydrate gypsum is changed into fine needle-shaped hemihydrate gypsum under saturated steam pressure, and then crystal form stabilization treatment is carried out to obtain the calcium sulfate hemihydrate crystal whisker, wherein the method has high requirement on the quality of raw materials, high production cost and limited application; the ordinary pressure acidification method means that the high-concentration dihydrate gypsum suspension can be converted into needle-shaped or fibrous calcium sulfate hemihydrate whiskers in an acid solution at a certain temperature. Compared with a hydrothermal method, the method does not need a high-temperature pressure-resistant container, has low quality requirement on raw materials, is easy to reduce cost, but needs to discharge a large amount of acid sludge, has serious pollution and has a general development prospect.
