  普通的消泡剂价格十分高,购买一吨这样的产品,也会耗费你一万到两万元钱。而高效工业消泡剂,价格好,你将会发现工业生产中会频繁使用到这样的产品。即使在苛刻的条件下,高效工业消泡剂也能发挥很好的消泡作用。现今,它已然被应用在发酵、维修、染色等行业中不同种类的消泡剂,都有各自的特点。对于高效工业消泡剂而言,显然它是工业方面使用比较频繁的消泡剂。那么,高效工业消泡剂有什么样的特点呢?它的优点有很多,它使用成本相对来说比较低,能够很好地溶解在水里,具有约百分九十八的消泡率,而且能够在二十度到一百五十度温度范围中起到相应的消泡作用。

  选择消泡剂要符合以下特点:
  1、在起泡液中不溶或难溶
  为破灭泡沫,消泡剂应该在泡膜上浓缩、集中。对破泡剂的情况,应在瞬间浓缩、集中,对于抑泡的情况应经常保持在这种状态。所以消泡剂在起泡液中是过饱和状态,只有不溶或难溶才易于达到过饱和状态。不溶或难溶,才易于聚集在气液界面,才易于浓缩在泡膜上,才能在较低浓度下发挥作用。用于水体系的消泡剂,活性成分的分子,须为强疏水弱亲水,HLB值在1.5-3范围,作用才最好。
  2、表面张力低于起泡液。
  只有消泡剂分子间作用力小,表面张力低于起泡液,消泡剂微粒才能够在泡膜上浸入及扩展。值得注意的是,起泡液的表面张力并非溶液的表面张力,而是助泡溶液的表面张力。
  3、与起泡液有一定程度的亲和性。
  由于消泡过程实际上是泡沫崩溃速度与泡沫生成速度的竞争,所以消泡剂必须能在起泡液中快速分散,以便迅速在起泡液中较广泛的范围内发挥作用。要使消泡剂扩散较快,消泡剂活性成分须与起泡液具有一定程度的亲和性。消泡剂活性成分与起泡液过亲,会溶解;过疏又难于分散。只有亲疏适宜,效力才会好。
  4、与起泡液不发生化学反应。
  消泡剂与起泡液发生反应,一方面消泡剂会丧失作用,另一方面可能产生有害物质,影响微生物的生长。
宝乐彩票平台  5、挥发性小,作用时间长。

  消泡剂的种类繁多,大致分为:聚醚改性硅消泡剂,有机硅消泡剂,矿物油消泡剂,非硅消泡剂等等,有已乳化的和未乳化之分。我们在怎样选择合适的消泡剂时就需要谨慎考虑。烟台恒鑫化工生产各种工业消泡剂,包括发酵行业、石棉瓦行业、污水处理行业、纺织印染行业等,消泡抑泡性能好,
