Combined with the fundamental characteristics of FBFQ plastering anhydrite ,from construction technology and technical measures the application of plastering anhydrite in building engineering is introduced.

结合FBT-Q 粉刷石膏的基本性能，从FBT-Q的施工工艺和采取的技术措施介绍了粉刷石膏在建筑工程中的应用，指明了粉刷石膏的材质特点，以保证其在工程应用中的优越性。

The structures and properties of gypsum and anhedritite are introduced in this paper.

介绍了石膏及硬石膏的结构及性质。

These phenomena are explained as follows thatduring the hydration of α-hemihydrate gypsum, cations have significance influence on theζpotential of α-hemihydrate gypsum, thereby the dispersed state and the dissolving ratesof α-hemihydrate gypsum are changed. But anions have slight influence because it isdifficult that anions enter the double-layer.

产生这一现象的主要原因是：在α半水石膏的水化硬化过程中，阳离子对α半水石膏的ζ电位产生较大影响，从而改变了α半水石膏颗粒的分散程度和溶解速度；而阴离子很难进入双电层，因此对水化过程的影响较小。

The invention relates to a method for adopting a compound reducing agent to reduce and decompose phosphogypsum; the method comprises the following steps of: using high-sulphur coal and coal gangue to prepare the compound reducing agent; utilizing tail gas to dry the phosphogypsum and the compound reducing agent which are ground and mixed evenly and then transferred into a reducing and decomposing furnace; carrying out reduction and decomposition till the reaction is completed.

要約 本发明涉及一种采用复合还原剂还原分解磷石膏的方法，该方法将高硫煤和煤矸石配成复合还原剂，再将磷石膏、复合还原剂利用尾气烘干、磨细后混匀送入还原分解炉，进行还原分解，直至反应完全。

The fields of application of calcined FGD gypsum were gypsum wallboard,building plasters,self-leveling floor plaster,etc;The fields of application of uncalcined FGD-gypsum were cement, agricultural soil amendment, etc.

经煅烧的脱硫石膏的应用领域主要有：石膏墙板、建筑灰泥、自流平地板灰泥等；未经煅烧的脱硫石膏的应用领域主要有：水泥、农业土壤改良等。

The results show that adding water reducer on gypsum before grinding gypsum can cause good grindingaid effect and improve remarkably the dispersing and fluidity of gypsum plaster.

减水剂磨前掺入可显著提高石膏的粉磨效率，提高石膏的比表面积，使颗粒粒度细化；可明显增加减水剂在石膏表面的吸附量与ζ电位，其分散能力大大优于减水剂同掺。

The technology of water washing can remove all above-mentioned harmful impurities except of P〓O〓 in crystal lattice. However, the feasibility of water washing technology may rely on the ability in investment as the initially required investment size is big. Also, this technology may cause a secondary pollution as the process generates large amount of waste water. Organic matters can be removed by a floating technology. Lime may be used as a neutralizing agent which transforms watersoluble P〓O〓, F〓 into salts of low solubility. Grinding can improve the crystal morphology and the gradings of PG. A combined technology of neutralization with grinding may have the advantages of both.

水洗可除去除共晶P〓O〓以外的所有杂质，但存在一次性投资大、工艺复杂、污水排放造成二次污染等问题；浮选可除去磷石膏中的有机物；石灰中和使有害态的可溶磷、氟转化为惰性的难溶盐；适当的球磨可有效改善磷石膏的颗粒形貌与级配；筛分可除去有害杂质含量特别高的部分，提高磷石膏品质；球磨与石灰中和结合的预处理工艺，既消除了主要有害杂质的影响，又改善了磷石膏颗粒结构与级配。

Experimental results show: PG differs significantly from natural gypsum in grading and crystal morphology. PG crystals are coagulation of course tabular grains with a relatively uniform size and thickness and give a normal distribution of gradings.

研究结果表明：磷石膏的颗粒级配、形貌与天然二水石膏存在显著差异，其颗粒级配呈正态分布，二水石膏晶体粗大、均匀，以板状为主。
