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.

　　根據純度不同，萘可分為工業(yè)萘和精萘。工業(yè)萘的純度一般約為96%。工業(yè)萘進一步提純脫除雜質及脫硫后，可得到高純度的精萘。

　　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.

　　工業(yè)萘是基礎化工原料，主要用于生產減水劑、擴散劑，是生產合成樹脂、增塑劑、橡膠防老劑，表面活性劑，合成纖維，染料、醫(yī)藥和香料等的原料。

　　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.
                

　　通過上面的一些資料我們已經了解了，工業(yè)萘就是純度較低的萘。而在文章的開頭小編還提到了一個詞：減水劑，所謂的減水劑又是什么東西呢?

　　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?

　　減水，顧名思義就是減少水的用量。工業(yè)萘的相關生產制造中，有哪些地方需要用到減水劑呢?答案就是建筑業(yè)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.

　　減水劑是一種在維持混凝土坍落度不變的條件下，能減少拌合用水量的混凝土外加劑。加入混凝土拌合物后對水泥顆粒有分散作用，能改善其工作性，改善混凝土拌合物的流動性;，達到減少單位水泥用量，節(jié)約水泥等目的。

　　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.
