The dosage and type of clay were the main influence factors of the chroma and turbidity of the lubricating oil.

正交试验结果表明白土用量和白土类型分别是影响白土吸附后润滑油的色度和浊度的主要因素。

Raymond Red Star machines widely used in production of barite, calcite, potash feldspar, talcum, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, swelling earth, kaolin, cement, phosphate rock, gypsum, glass, insulation materials, etc. Mohs hardness is not greater than 9.3 and humidity below 6% of non-inflammable mineral, chemical and construction industries more than 280 kinds of materials of high fine flour processing, particle size 80-325 mesh finished products within the scope of arbitrary regulation, part of the material up to 600 mesh.

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。

With the pHysical and chemical method this paper studies the bleach technology of the Waste edible oil from catering trade, has respectively discussed the bleachmechanism of the Waste edible oil with three bleach reagents of different types--active bleaching earth, Diaobaikuai and peroxide. On the base of discussing the influencing factor of bleachability, reaches three bleaching technology conditions. After comparing the bleach effect between the unitary bleach reagent and the match bleach reagent ,selects the best bleach reagent and its bleach technology condition.

采用物理和化学的方法研究餐饮业废油脂的脱色工艺，分别探讨了不同类型的脱色剂——活性白土、雕白块和双氧水对废油脂脱色的机理；在讨论了影响脱色率因素的基础上，研究出三者脱色的工艺条件；并对比了单一脱色剂脱色效果以及脱色剂复配的脱色效果；筛选出最佳的脱色剂及其脱色工艺条件。

The studies on crystallochemical structure of montmorilloni te indicates that the montmorillonite has a higer ordering degree and a larger l ayer charge.

蒙脱石的晶体化学结构研究表明，蒙脱石有较高的有序度和较大的层电荷，因此，上天梯膨润土适合于制备高效活性白土。

The results for rubber seed oil refining were as follows: For the crude solvent-extracted oil, it was first degummed 20 min by 0.04% H3PO4 at 60℃, and neutralized 10 min by 0.15% CaCO_3, then treated with 5% bleaching clay, and refined oil could be obtained. For the machine-squeezed oil, it was first degummed 20 min by 0.04% H3PO4 at 90℃, and neutralized 10 min by 0.15% CaCO3, then treated with 15% bleaching clay, and refined oil could be obtained.

橡胶籽油精炼结果表明：溶剂尤其是以石油醚等提取毛油的色泽最好；溶剂提取毛油在60℃下、0.04%的H_3PO4(含量为85%)、20min脱胶和0.15%的CaCO3中和搅拌10min后，再在20min、油重5%白土脱胶脱色较好；机榨毛油在90℃下、0.04%的H3PO4(含量为85%)、20min脱胶和0.15%的CaCO3中和搅拌10min后，再在20min、油重15%白土脱胶脱色的精炼机榨油次之。

Kaolin is further broken down into: gaolin gaolin multi-batch water, and so on, these white clay were commercial production but now coated paper with a white clay, basically the gaoling group is referred to as gaolin, is coated with white clay.

高岭土又进一步细分为：高岭土、多水高岭土等，这些白土都已经被商品化生产但是，现在涂布纸用白土中，基本上把高岭石类都称为高岭土，也就成为涂布用白土的代名词。

After oil is recovered from it, the bleaching clay is regenerated by acid activation, ignition, baking and acid washing methods.

先从废白土中回收油脂，然后分别采用酸活化法；灼烧法；焙烧-酸洗法工艺进行再生，并对再生工艺条件进行了研究，使再生白土达到最佳的脱色率。

The brackish water that we drink Creeps with a loathsome slime, And the bitter bread they weigh in scales Is full of chalk and lime, And Sleep will not lie down, but walks Wild-eyed and cries to Time.

我们喝的不堪入口的水，渗入了令人恶心的污秽，他们按斤两分配的苦面包，里面全是白粉末和白土胶睡神不会躺下，却站着走，暴躁不安地对时间高吼。

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。
