1. Ultrafine, purified and modified anhydrous calcium sulfate.

　　目前，國內已有專 家將二水石膏經過脫不夜墓、超細千荡、提純和改性等一系列加工后，制形成一種稱為凱色粉的高  檔產品泰锦。它能夠取代立德粉绅踪、超細的煅燒高嶺土、滑石诗实、重質碳酸鈣（或輕鈣）兄诱，能夠替代局部鈦白粉用作橡膠、塑料昆饲、涂料中的填料旧育。由于中工后的我水硫酸鈣與有機資料親合力強，能夠大量摻入蝗袄，摻入量為重鈣或輕鈣摻入量的2倍以上路揖，制品的強度、剛性贮爹、外表硬度斋射、耐酸性、耐候性但荤、熱穩(wěn)定性均有所進步绩鸣，而每噸制品的本錢即降落了200多元。依據他們的成果，在山西晉城已建成加工廠停止批量消費呀闻。凱色粉已在江蘇化借、上海、海南等地推行應用捡多。

　　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.

　　依據實驗材料蓖康，石膏委員會專 家組準備在湖北大冶靈鄉(xiāng)用優(yōu)質硬石膏加工微米級硫酸鈣，用于橡膠垒手、塑料及涂料中蒜焊，與愷色粉一樣將得到很好的應用。而優(yōu)制硬石膏無需煅燒科贬，又能夠簡化一些加工廠工藝泳梆，儉省能源，降低本錢渺广，進步產品的市場競爭才能捣睬，有望大量開展。

　　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. 輕質湃鳖、高強克蝶、耐水、保溫的石膏復合墻狮最。

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

　　長期以來搔肉，國內不少單位開發(fā)了一些石膏復合墻體，如輕鋼龍骨紙面石膏板夾巖板復合墻體泌祥、纖維石膏板或石膏刨花板等與龍骨的復合墻體蓉止，加氣（或發(fā)泡）石膏保溫板或砌塊復合墻體，石膏與聚苯泡沫板放暇、稻草板非畜、蜂窩紙芯、麥秸芯板等復合的大板等辛蕊。特別是纖維加強低鹼主水泥（GRC板）或硬石膏水泥壓力板與各種有機亦弛、無機芯材復合墻體，既能夠做內墻也能夠做外墻同衣。有條件的地域和工廠竟块，可與建筑設計、施工及建立單位親密配合耐齐，組織消費各種裝配工石膏復合墻板浪秘、屋面乃至包括門客的盒子間。這種工廠化消費建筑物各種組件埠况，然后現(xiàn)場裝配耸携，可進步建筑速度和質量，降低造價，減輕工人的勞動強度和環(huán)境污染夺衍，是新型建材的開展方向狈谊。

　　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.
