| | アルミノケイ酸NA Usage And Synthesis |
| 外観 | 径: 1.4～2.0mm | | 定義 | 本品は、アルミニウムケイ酸のナトリウムの水和物である。 | | 溶解性 | 水及び一般の有機溶媒にほとんど溶けない。 | | 化粧品の成分用途 | 親水性増粘剤、研磨.スクラブ剤 | | 化学的特性 | beige granules | | 使用 | Molecular sieves, 5Å is an anticaking and conditioning agent used to improve flow properties and prevent caking. It absorbs moisture up to 75% of its weight. It functions as a moisture absorbent, moisture barrier, carrier, and processing aid. It is used in salt, cake mixes, powdered sugar, nondairy creamers, and dry mixes. Usage level ranges from 1 to 2%. It is also termed sodium aluminosilicate. | | 使用 | Molecular sieves, 5A, 3-4mm (0.12-0.16in) dia. Pellets is used as an sorbent. | | 一般的な説明 | Molecular sieves are crystalline metal aluminosilicates having a three-dimensional interconnecting network of silica and alumina tetrahedra. Natural water of hydration is removed from this network by heating to produce uniform cavities which selectively adsorb molecules of a specific size. The 5A form has divalent calcium ions in place of sodium cations give apertures of ~5?, which exclude molecules of effective diameter >5? (for example: all 4-carbon rings and iso-compounds). These molecular sieves can adsorb compounds such as n-butane, n-butyl alcohol, propane, docosane and dichlorodifluoro-methane. |
