查询词典 lime kiln

The hydration process of lime has important influence on lime slaking rate、 particle size and specific surface, so it is significant to research the hydration process.

生石灰的转化率是衡量消化产物品质的重要因素；熟石灰的粒径越小，比表面积越大，其利用率也就越大；生石灰的消化工艺无论是对消化产物的粒径、比表面积和孔隙率还是含水率都有很大的影响，因此有必要进行实验研究。

In this paper, the mechanism research of lime dry hydration was studied using small equipment. Then the effect tendencies of operational parameter of hydration process(water/solid) on lime slaking rate、 particle size and specific surface was put forward.

本文利用小型机理实验装置进行了石灰干式消化机理实验研究，得出了消化工艺操作参数对生石灰的转化率、消化产物的粒径和比表面积的影响趋势。

Background: The main raw materials of lime sand bricks are tailings of silicon materials and calcium lime. They are standard bricks made through mixing, pressing and autoclaving. Their features include beautiful appearance, good quality and high solidness. An ideal substitute for clay bricks, they can be widely used in the base, the interior and exterior walls of constructions.

一、项目背景：灰砂砖是以硅质材料尾砂和钙质材料石灰为主要原料，经混和、压制、蒸压工艺制成的标砖，具有外观质量好、强度高等性能，可广泛应用于建筑物基层，底层及内、外墙体，是理想的实心粘土砖的替代产品。

Based on CaO dydration exothermity, the special test unit is designed to measure and compare the quick lime hydration actives, the conclusion which is useful for the adsorbent selection of interior furnace Calcium spary moisture increase hydration gas desulphuring technique and the quick lime adsorbent simple wet desulphuring techwique is achieved.

基于CaO水合放热，设计专用试验装置对生石灰水合活性进行测试比较，其结果对炉内喷钙增湿水合烟气脱硫和以生石灰为吸着剂的简易湿法脱硫技术吸着剂选择有指导意义。

In this text, on the base of gradation design, the pavement performances of lime-fly ash stabilized aggregates and lime-fly ash mortar under controlling fine aggregates gradation are studied, and contrasted with the mixtures which are under uncontrolling fine aggregates gradation, including mechanical performance, stableness, anti-brushing performance, the anti-crack performance, and drawing the conclusion of controlling fine aggregates gradation.

在配合比设计的基础上，研究了控制细集料级配的二灰砂浆和二灰碎石混合料的力学性能、稳定性能，以及二灰碎石的抗收缩性能、抗冲刷性能，并与不控制细集料级配的二灰砂浆和二灰碎石混合料的路用性能进行了对比，得出实际施工中应控制细集料级配的结论。

The surfactants used in syndet are mild and high efficiency, little skin irritation. As the pH value of syndet is neutral (7) or skin neutral (5.5), they neither alter the pH of the skin nor cause puffiness skin layer. Due to the absence of lime soap formation there is no problem of skin irritation causedby lime soap residues remaining on the skin.

合成皂所采用的表面活性剂更加温和，对皮肤的刺激性非常小，而且整体呈现中性(7)或者与健康皮肤相近的pH值（5.5），所以对皮肤pH值影响很小，同时避免了长期使用碱性皂引起的皮脂流失，由于没有钙皂形成，避免了钙皂沉积造成的刺激。
