To understand industrial naphthalene, we must first know what "naphthalene" is. Naphthalene, also known as naphthalene, is a colorless and shiny flake crystal. Insoluble in water, easy to sublimate, can volatilize with water vapor and has a special smell.

根据纯度不同，萘可分为工业萘和爱游戏app全站登录。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，可得到高纯度的爱游戏app全站登录。

According to different purity, naphthalene can be divided into industrial naphthalene and refined naphthalene. The purity of industrial naphthalene is generally about 96%. High purity refined naphthalene can be obtained after further purification, impurity removal 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, which is mainly used in the production of water reducer and dispersant. It is also a raw material for the production of synthetic resin, plasticizer, rubber antioxidant, surfactant, synthetic fiber, dyes, medicine and spices.

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?

We have learned from the above data that industrial naphthalene is naphthalene with low purity. At the beginning of the article, the Xiaobian also mentioned a word: water reducing agent. What is the so-called water reducing agent?

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。

Water reduction, as the name suggests, is to reduce the amount of water. Where do water reducing agents need to be used in the production of industrial naphthalene? The answer is concrete in construction.

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 volume under the condition of maintaining the constant slump of concrete. After adding the concrete mixture, it can disperse the cement particles, improve its workability and improve the fluidity of the concrete mixture;, Achieve the purpose of reducing unit cement consumption and saving cement.
