查询词典 condensation trail

Ceilings should be ac-cessible for cleaning, and ideally, the surface should he coved where ceilings and walls meet In many food-production areas, the ceiling must have thermal in-sulation This may be necessary either to prevent surface condensation or to reduce the energy costs of maintaining low environmental temperaturesWalls should also be insulated, to prevent surface condensation They should be free from rising damp and be protected, where appropriate, from damage by forklift trucks, by use of a guard rail In modern factories, there is always a coved surface where walls meet the floor It is also usual for there to be a coved surface where walls join at right angles.

天花板应该交cessible清洗、最理想他表面复岩下天花板和墙壁应满足许多粮食产区，天花要有热的绝缘要么这可能需要防止或者减少表面凝结能源维护成本低，对环境温度也应绝缘墙壁、应防止表面凝结他们免于受到保护和潮湿上涨，酌情从叉车损坏，用现代铁工厂门卫、凡事总有复岩面墙那里迎接地板也是平日没有可能凡参加面复岩墙成直角。

The results showed that condensation temperature and condensation pressure increased with increasing inlet air wet-bulb temperature.

对影响板式蒸发式冷凝器热工性能的主要因素——空气的湿球温度、冷凝温度、相对湿度做了实验研究。

When the condensation of water discharge is completed, followed by emission of steam due to condensation of water vapor than the volume GLOBE VALVE and flow, causing the upper and lower valves generate pressure, the steam valve of the suction flow rapidly closing.

当凝结水排放完毕，蒸汽随后排放，因蒸汽比凝结水的体积和流速大，使阀片上下产生压差，阀片在蒸汽流速的吸力下迅速关闭。

Since the condenser pressure depends on condensation temperature, the factor influencing condensation temperature is also the factor influencing vacuum degree of condenser.

由于凝汽器压力取决于凝结温度，因此，影响凝结温度的因数也就是影响凝汽器真空度的因数。

The invention uses the industry byproduct in production of sulfonation-process phenol or the byproduct (Na2SO3 content is 60-85percent) in production of p-cresol and sodium hydrosulfite to produce the aliphatic high range water reducer and takes acetone, formaldehyde, industry byproduct, sulphite or sodium pyrosulfite as raw materials and then sulfonation and condensation reactions are carried out in aqueous medium, the reactant weight ratio is acetone: formaldehyde: sulphite plus industry byproduct: water is equal to 1:2.5-4.5:1.5-2.6:4.0-6.0, the mass concentration of the condensation compound obtained is 30-42 percent, and the viscosity thereof is 20-100m.

本发明利用磺化法苯酚生产中的工业副产品，或者对甲酚和保险粉生产过程中副产品(Na 2 SO 3 含量在60～85％)生产脂肪族高效减水剂，采用丙酮、甲醛、工业副产物、亚硫酸盐和或焦亚硫酸钠作为原材料，在水介质中进行磺化和缩合反应，反应物的质量比为丙酮∶甲醛∶亚硫酸盐副产品∶水＝1∶2.5～4.5∶1.5～2.6∶4.0～6.0，所得到的缩合物的质量浓度为30～42％，粘度为20～100m。

Methyl isobutyl ketone is a good origanic slovent and the advanced process for producing MIBK is one-step synthesis by gas-phase condensation and hydrogenation of acetone. In this process, the key technology is to develop the multi-fuctional catalyst, which has both the ability of hydrogenateon and condensation, as well as suitable acid-base sites.

甲基异丁基酮是一种优良的有机溶剂，先进的生产方法是丙酮气相缩合加氢一步法，该工艺关键的技术是开发高效的双功能催化剂，即催化剂同时具有缩合、加氢以及适宜的酸、碱性质。
