红星机器生产的雷蒙磨广泛适用于重晶石、方解石、钾长石、滑石、大理石、石灰石、白云石、莹石、石灰、活性白土、活性炭、膨润土、高岭土、水泥、磷矿石、石膏、玻璃、保温材料等莫氏硬度不大于9.3级，湿度在6%以下的非易燃易爆的矿产、化工、建筑等行业280多种物料的高细制粉加工，成品粒度80—325目范围内任意调节，部分物料最高可达600目。

Was established in October 2005, mainly the production of indoor and outdoor decorative wall waterproof putty powder and paint the plaster putty powder, as well as the wall finish used.

陕西锦宏新型装饰材料有限公司成立于2005年10月份，主要生产室内外墙面装饰防水腻子粉和粉刷石膏腻子粉，以及墙面所用的面漆。

Use of new materials, new technology, the new formula, successfully developed a drug-free imports of polymer materials, gypsum-based environmental campaign joints powder, Goufeng powder, putty powder, fill our decorating materials sector a big blank, And adopted the designated testing organizations detection, green building materials obtained state certification.

采用新材料、新工艺、新配方，成功研制开发了以进口无毒高分子材料、石膏为基础的环保系列接缝粉、勾缝粉、腻子粉，填补了我国装潢材料界的一大空白，并通过了国家指定检测机构检测，同时获得了国家绿色建材认证。

The tests study influence of L retarder on setting time, hydrating characteristics and setting strength of building gypsum in comparison with effective result of often used retarder－ citric acid and sodium pyrophosphate.

研究了L缓凝剂对建筑石膏的凝结时间、水化特点以及硬化体强度的影响，并与常用的缓凝剂—柠檬酸、焦磷酸钠的作用效果进行了对比。

When replaced 50% cement with high calcium compound steel slag, activate concrete with quicklime and phosphohydrate, the effect is obvious.

高钙灰与钢渣取代50％的水泥时，分别采用生石灰和磷石膏进行活性激发。效果显著。

The preparation process of modified quicklime are studied. The advantage of process is that milling cost reduces, the fine of phosphorus gypsum increases, construction is simplified, environment waste falls.

本文研究了改性生石灰的配制工艺，认为此工艺的优点在于不仅可以降低粉磨能耗，提高磷石膏的细度，激发其活性，而且还能简化施工工艺流程，降低环境污染。

According to the in situ environments of deep copper mines, the authors have developed new types of underway LHD road s, including a cement mine waste concrete road , a plaster mine waste concrete road , a composite jelling agent ore powder concrete road and a block mine waste rolled road , ensuring high intensity underway transport.
