精萘廠家解讀什么是精萘和它有什么用處

來源:http://yaoguangyi.cn/ 日期:2020-08-07 發(fā)布人:admin
  要了解工業(yè)萘,首先我們要先知道“萘”是什么。萘,又稱并萘,是一種無色有光澤的片狀結(jié)晶。不溶于水,易升華,能隨水蒸氣揮發(fā),有特殊氣味。
  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(jù)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(jìn)一步提純脫除雜質(zhì)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(chǔ)化工原料,主要用于生產(chǎn)減水劑、擴(kuò)散劑,是生產(chǎn)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(jīng)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(gè)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(guān)生產(chǎn)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(duì)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(dòng)性;,達(dá)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.
  以上是關(guān)于精萘和工業(yè)萘用處的相關(guān)介紹,相信大家一定有所了解了,如想要了解更多內(nèi)容歡迎點(diǎn)擊精萘廠家http://yaoguangyi.cn官網(wǎng)。
  The above is about refined naphthalene and industrial naphthalene use related introduction, I believe you must have understood, if you want to know more content, welcome to click refined naphthalene manufacturers http://yaoguangyi.cn Official website.
