氣泡袋的穩定機理是什麽意思?

  有關離子的氣泡袋,主要是由於靜電斥力隱含的決定機製。種方式是氣泡袋富集於表麵的氣泡膜。氣泡袋吸附分子的極性基團的水旭保護膜的層形成。如果氣泡袋分子帶電荷,氣泡,因此帶上電荷。彼此接近的過程中混合的氣泡的氣泡的靜電斥力,從而使彼此分開的。
  The bubble bag of ions is mainly due to the underlying mechanism of electrostatic repulsion. The first way is to concentrate the bubble bag on the surface of the bubble film. The bubble bag adsorbs the polar group of the molecule to form a layer of water Xu protective film. If the bubble bag molecule is charged, the bubble, therefore, is charged. The electrostatic repulsion of bubbles mixed in the process of approaching each other, thereby separating them.
  此效果和保持穩定的乳狀液,類似的機製,以防止破乳化劑。在混凝土氣泡袋的情況下。在攪拌下,當氣泡靠近對方,小氣泡的大氣泡,很容易。其次通過攪拌寬鬆浮力的雙重作用大的氣泡上升到表麵的混凝土漿,大泡沫破滅的被消耗,減少空氣含量的混凝土漿。
  This effect is similar to maintaining a stable emulsion, a mechanism to prevent demulsifiers. In the case of concrete bubble bags. Under stirring, when the bubble is close to each other, the big bubble of the small bubble is very easy. Secondly, by mixing the double effect of buoyancy, the large bubbles rise to the surface of the concrete slurry, the large foam is shattered and consumed, and the air content of the concrete slurry is reduced.

  由於非離子型表麵活性劑的富集層可以負責的氣泡,因此水化層的膜泡穩定性的因素,導致在非離子型和離子型的氣泡膜,氣泡袋中夾帶氣泡尺寸較大的比較差。對於非離子型表麵活性劑中的主要分子機製穩定的水化層。的第二表麵上的氣泡和氣泡穩定地形成水合層。水合層可以有一些水分子的厚度,它的作用是在氣泡分離,該係統是穩定防止絮凝的係統。這種效應被認為是發生在一種非離子型表麵活性劑,以形成富集層。
  Because the enrichment layer of nonionic surfactant can be responsible for the bubbles, the only factor for the stability of the bubbles in the hydration layer leads to the relatively poor size of the bubbles in the nonionic and ionic bubble films. For non-ionic surfactants, the main molecular mechanism of the hydration layer is stable. The bubbles and bubbles on the second surface of the form a hydration layer stably. The hydrated layer can have the thickness of some water molecules. Its function is to separate bubbles. This system is a stable system to prevent flocculation. This effect is believed to occur in a non-ionic surfactant to form an enrichment layer.
  公知的,陽離子型和非離子型表麵活性劑不能形成不溶性鈣鹽的沉澱,但是這兩種類型的表麵活性劑,這是確實的夾帶作用。此外,年齡組可形成可溶性鈣鹽,如烷基磺酸酯陰離子混合物,也有很好的引氣效果。因此,“不溶性膜穩定機製”可能是重要的,但不是必須的。
  It is known that cationic and non-ionic surfactants can not form insoluble calcium salt precipitation, but these two types of surfactants, which is indeed entrainment. In addition, the age group can form soluble calcium salts, such as alkyl sulfonate anion mixture, which also has good air entraining effect. Therefore, "the mechanism of membrane stability" may be important, but it is not necessary.
