To understand industrial naphthalene, we must first know what naphthalene is. Naphthalene, also known as naphthalene, is a kind of colorless and glossy flake crystal. Insoluble in water, easy to sublimate, volatile with water vapor, with a special smell.

　　根据纯度不同，萘可分为工业萘和精萘。工业萘的纯度一般约为96%。工业萘进一步提纯脱除杂质及脱硫后，可得到高纯度的精萘。

　　According to the different purity, naphthalene can be divided into industrial naphthalene and refined naphthalene. The purity of industrial naphthalene is about 96%. High purity naphthalene can be obtained by further purification and desulfurization of industrial naphthalene.

　　工业萘是基础化工原料，主要用于生产减水剂、扩散剂，是生产合成树脂、增塑剂、橡胶防老剂，表面活性剂，合成纤维，染料、医药和香料等的原料。

　　Industrial naphthalene is a basic chemical raw material, mainly used in the production of water reducing agent, dispersant, synthetic resin, plasticizer, rubber antioxidant, surfactant, synthetic fiber, dye, medicine and perfume.
                

　　通过上面的一些资料我们已经了解了，工业萘就是纯度较低的萘。而在文章的开头小编还提到了一个词：减水剂，所谓的减水剂又是什么东西呢?

　　Through some of the above information, we have learned that industrial naphthalene is naphthalene with lower purity. And at the beginning of the article, we also mentioned a word: water reducer, what is the so-called water reducer?

　　减水，顾名思义就是减少水的用量。工业萘的相关生产制造中，有哪些地方需要用到减水剂呢?答案就是建筑业的混凝土。

　　Reducing water, as the name implies, is to reduce the amount of water. In the related production and manufacturing of industrial naphthalene, which places need to use water reducer? The answer is concrete in construction industry.

　　减水剂是一种在维持混凝土坍落度不变的条件下，能减少拌合用水量的混凝土外加剂。加入混凝土拌合物后对水泥颗粒有分散作用，能改善其工作性，改善混凝土拌合物的流动性;，达到减少单位水泥用量，节约水泥等目的。

　　Water reducing agent is a kind of concrete admixture which can reduce the mixing water amount under the condition of keeping the concrete slump constant. After adding concrete mixture, it can disperse cement particles, improve its workability and fluidity of concrete mixture, so as to reduce unit cement consumption and save cement.
