查询词典 gypsum

The Mobilcer and Mulrex emulsions are used primarily in construction board such as particleboard, oriented strandboard, medium density fiberboard, hardboard, insulation board and gypsum board.

Mobilcer 和 Mulrex 这两种蜡乳液主要用于建筑板材，例如刨花板，定向刨花板，中密度纤维板，硬纸板，绝缘板和石膏板。

Aim: To evaluate the surface hardness and abrasion resistance of die stone model with the application of a new gypsum surface hardener.

目的：测定涂布超硬石膏表面硬化剂有机硅树脂前后石膏模型的表面硬度和抗磨损性能，为该石膏表面硬化剂的临床应用提供依据。

Hemihydrate can be used instead of gypsum.

半水物硫酸钙可以用来代替石膏。

The experimental results show that when the kinds of inorganic additives in the α-hemihydrate gypsum paste are different, both the shape and size of dihydrate gypsumcrystals that are formed during the hydration are different.

试验结果表明，无机外加剂的种类不同，α半水石膏水化时生成的二水石膏晶体的尺寸和形貌均不同。

FGD gypsum further into α-form calcium sulfate hemihydrate by heating in an aqueous solution consisting of some alkail earth metal salts and sulfuric acid or chlorhydric acid at the atmospheric pressure has been studied in this subject.

FGD残渣在碱土金属盐类的盐溶液中，在丁二酸、丙三醇等结晶改良剂的作用下，与大气压下加热脱水生成α半水石膏。

It is found that the concentration of sulfuric acid in liquid and the reaction temperature are the most sensitive factors for this process. Increasing the ratio of solid to liquid is disadvantageous for growth of crystals even though it does not effect obviously for the rate of dehydration of FGD gypsum. On the other hand,the more closed to the neutral range of pH value the liquid is adjusted,the better stability of the α-form calcium sulfate hemihydrate appear,the more favorable for modification of crystal habit the process is made.

研究中发现pH值和盐溶液浓度是影响FGD石膏脱水速度最敏感的因素，固液比虽然对脱水速度影响不大，但固液比增大对晶体生长和习性改良不利。pH值愈接近中性范围，愈能增强α半水石膏结晶在液相中的稳定性，有利于结晶习性改良。

Seeing its desiccation by negative pressure, recycle of crystal modifiers and preheating of raw gypsum, this technology has been rendered most efficient in producing calcium sulphate hemihydrate, with higher quality and lower energy consumption.

工艺中利用"闪蒸原理"进行负压干燥，媒晶剂溶液循环使用，媒晶剂溶液的余热预热生料，使得生产能力及产品质量大为提高，能耗大幅度降低。

" Plaster of paris: Quick-setting gypsum plaster consisting of a fine white powder, calcium sulfate hemihydrate, which harden s when moistened and allowed to dry."

熟石膏：一种快凝石膏灰浆，为精细的白粉，掺水后再次干燥时硬化。

" Plaster of paris: Quick-setting gypsum plaster consisting of a fine white powder, calcium sulfate hemihydrate, which hardens when moistened and allowed to dry."

熟石膏：一种快凝石膏灰浆，为精细的白粉，掺水后再次干燥时硬化。

Single factor test was employed to investigate some factors effecting the compressive strength of hydratedα-plaster of Paris which was made by Aqueous Salt Solution Method in atmospheric pressure such as crystal modifiers,aqueous salt solution,emperature of water to washα-hemihydrate gypsum powder,product drying temperature,product grain size.

采用单因素实验考察了媒晶剂、盐介质、洗涤水温度、产品干燥温度、产品粒度等因素对常压盐溶液法制备α-半水石膏的抗压强度的影响，实验结果表明：当媒晶剂为柠檬酸钠与Al3 +等的复合物(占盐溶液的质量百分比为1.0 %)、盐介质为15 %的KCl水溶液、洗涤水温度在98℃以上、产品干燥温度为110 - 130℃、产品粒度控制在7- 4 μm时，产品抗压强度可达4 4MPa

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
