1. Ultrafine, purified and modified anhydrous calcium sulfate.

　　目前，国内已有专 家将二水石膏经过脱不、超细、提纯和改性等一系列加工后，制形成一种称为凯色粉的高  档产品。它能够取代立德粉、超细的煅烧高岭土、滑石、重质碳酸钙（或轻钙），能够替代局部钛白粉用作橡胶、塑料、涂料中的填料。由于中工后的我水硫酸钙与有机资料亲合力强，能够大量掺入，掺入量为重钙或轻钙掺入量的2倍以上，制品的强度、刚性、外表硬度、耐酸性、耐候性、热稳定性均有所进步，而每吨制品的本钱即降落了200多元。依据他们的成果，在山西晋城已建成加工厂停止批量消费。凯色粉已在江苏、上海、海南等地推行应用。

　　At present, domestic experts have produced a kind of high-grade product called Kaise powder after a series of processing of dihydrate gypsum, such as removal, ultrafine, purification and modification. It can replace lithopone, ultra-fine calcined kaolin, talc, heavy calcium carbonate (or light calcium), and can replace local titanium dioxide as filler in rubber, plastics and coatings. Due to the strong affinity between calcium sulfate and organic materials, it can be doped in large quantities, and the amount of doping is more than twice that of heavy calcium or light calcium. The strength, rigidity, surface hardness, acid resistance, weather resistance and thermal stability of the products have improved, while the cost of each ton of products has dropped by more than 200 yuan. According to their achievements, processing plants have been built in Jincheng, Shanxi Province, to stop mass consumption. Kaise powder has been applied in Jiangsu, Shanghai and Hainan.

　　依据实验材料，石膏委员会专 家组准备在湖北大冶灵乡用优质硬石膏加工微米级硫酸钙，用于橡胶、塑料及涂料中，与恺色粉一样将得到很好的应用。而优制硬石膏无需煅烧，又能够简化一些加工厂工艺，俭省能源，降低本钱，进步产品的市场竞争才能，有望大量开展。

　　Based on the experimental materials, the expert group of gypsum professional committee is preparing to process micron calcium sulfate with high quality anhydrite in Lingxiang, Daye County, Hubei Province, for use in rubber, plastics and coatings, which will be as well applied as Kay powder. The high-quality anhydrite does not need calcination, but also can simplify some processing plant processes, save energy, reduce costs, improve product market competitiveness, is expected to develop in large quantities.

　　2. 轻质、高强、耐水、保温的石膏复合墙。

　　2. Composite gypsum wall with light weight, high strength, water resistance and heat preservation.

　　长期以来，国内不少单位开发了一些石膏复合墙体，如轻钢龙骨纸面石膏板夹岩板复合墙体、纤维石膏板或石膏刨花板等与龙骨的复合墙体，加气（或发泡）石膏保温板或砌块复合墙体，石膏与聚苯泡沫板、稻草板、蜂窝纸芯、麦秸芯板等复合的大板等。特别是纤维加强低硷主水泥（GRC板）或硬石膏水泥压力板与各种有机、无机芯材复合墙体，既能够做内墙也能够做外墙。有条件的地域和工厂，可与建筑设计、施工及建立单位亲密配合，组织消费各种装配工石膏复合墙板、屋面乃至包括门客的盒子间。这种工厂化消费建筑物各种组件，然后现场装配，可进步建筑速度和质量，降低造价，减轻工人的劳动强度和环境污染，是新型建材的开展方向。

　　For a long time, many domestic units have developed some gypsum composite walls, such as light steel keel plaster board, rock plate composite wall, fiber gypsum board or gypsum particleboard and other composite walls with keel, air entraining (or foaming) gypsum insulation board or block composite wall, gypsum and polystyrene foam board, straw board, honeycomb paper core. Composite boards such as wheat straw core boards, etc. In particular, fiber reinforced low alkali main cement (GRC board) or anhydrite cement pressure plate and various organic and inorganic core composite walls can be used as both internal and external walls. Conditional areas and factories can closely cooperate with architectural design, construction and establishment units to organize and consume all kinds of assemblers'gypsum composite wallboard, roofing and even boxes including doors and guests. This kind of factory consumes all kinds of components of building, and then assembles them on site, which can improve the speed and quality of building, reduce the cost, reduce the labor intensity of workers and environmental pollution. It is the development direction of new building materials.
