化工专业英语课文翻译？课10气体AbsorptionGas吸收是一个重要的化工单元操作,特别是在重化学工业。煤气的净化和合成气体以及生产的盐酸、硫酸、指标酸、碳酸钠和漂白碱液,只提到最引人注目的例子,气体吸收过程的基本特征。自二十年代进行了广泛的研究结果,本单元操作的知识大大增加了。那么，化工专业英语课文翻译？一起来了解一下吧。
化工专业英语课文翻译如下：
Although the use of chemicals dates back to theancient civilizations,the evolution of what we know as the modern chemical industry started much more recently.
尽管化学品的使用可以追溯到古代文明时代，我们所谓的现代化学工业的发展却是非常近代（才开始的）。
It may be considered to have begun during the Industrial Revolution,about 1800,and developed to provide chemical raw materials industry.
可以认为它起源于工业革命其间，大约在1800年，并发展成为为其它工业部门提供化学原料的产业。
Examples are a lka li for so apmaking,bleaching powder for cotton,and silica and sodium carbonate for glassmaking.
比如制肥皂所用的碱，棉布生产所用的漂白粉，玻璃制造业所用的硅及Na2CO3，我们会注意到所有这些都是无机物。
廉价的铜催化剂允许高效合成N -芳基-，N -酰基-，或铵-（氮杂吲哚从ortho-alkynylbromoarenes）。范围广泛的这种多米诺的N -芳基化/hydro-achtungtrenungamin（四）化过程所强调的是合成高功能化的吲哚类，以及一个chek1/受体抑制剂药效值得注意的是，邻取代更多的空间位阻的苯胺衍生物是很好的耐受性（作品7，和8），以及氯化物作为功能，从而导致选择性制备取代的吲哚3激酶（–条目9–11）。以机制这一“氮配体的“铜催化转化实验表明，仲胺反应序列由分子间氢胺化，其次是分子内的N -芳基化。支持数据的德国学术交流中心（金，银），动画，和赛诺菲-安万特表示感谢
water-based polyurethane seldom use organic solvent in the process of preparation and usage. with lower content of volatileorganic contaminant. less bad effect to the natural environment, so PU develop fastly. however, much of disadvantages will be showed when compare PU with solvent polyurethane, for instance,badgloss offilm formation, long time of film formation ,bad resistence to water and wheather, high cost and so on. so it is necessary to change its properties,enhance its comprehensive performance and expand its range of application.
in this article, will useTDI 'PPG220 'DMPA as the raw matetial to
compose moisture disintegration PU., and then, make WPUA by emulsion polymerization to the acrylic monomer. by the process of composing wpua, discuss what infuluence its appearance, density,stability,rigidity of film,raw material quantity and technological conditions may cause. we will find the best raw material and tech condition for composing the WPUA.
research shows:
under the condition as follows: prepolymer temprature at 60·C, prepolymer time is 300 min, content of DMPA at 8%, content of crosslinking agent TMP at 8%, and degrees temperature at 30℃, we can get the best WPUA with best performance of painting film.

As organic solvent is less used during preparation and use of Water Borne Polyurethane, PU product is low in VOC(volatile organic compounds),with little impact on the environment ,which has grown rapidly in recent years. In contrast with PU ,However,Solvent Polyurethane still have manyshortcomings,such as deficient gloss film,slower film formation,weak inwater proof and weather resistance,fancy price and so on.
In toluene diisocyanate (TDI), polyether polyols (PPG220), dimethylolpropionic acid (DMPA) as raw material, and then some synthetic PU with acrylic monomers on the emulsion polymerization of acrylic modified modification of waterborne polyurethane emulsion (WPUA). Through a series of modified synthetic latex, discusses its appearance, latex coated membrane stability, viscosity, hardness, raw material usage and the processing conditions on the performance of the product on the synthesis of waterborne acrylic polyurethane emulsion formulation and process of the best material conditions.
Research shows that the temperature gets together for 60 degrees, by time 300min, DMPA content 8%, crosslinking agent for 1%, TMP content and degree to 90% for 30 degrees Celsius, and temperature, the emulsion and the coating performance is the best.
