Aluminium powder - Import export

Chemical appearance: The chemical appears as some translucent flakes, granules or powder. It tends to cake when exposed to an atmosphere will high concentrations of moisture or when water is poured on it. It is highly water soluble and not toxic to the users. Chemical application and strengths: The substance is not reactive with most of the naturally occurring elements. However, it reacts with sodium bicarbonate to form a thick blanket of carbon dioxide. A foam stabilizer is added to the reaction to create a viable carbon dioxide layer that can effectively lock out oxygen from the burning material. This is the most common substance in many fire extinguishers used in Japan and India. It is also used as a firming industry in the human food industry, especially for starch. It commonly called E520. The same substance is also used in animal feeds to deal with bacteria that may be lurking around. In addition, it is used a deodorant and a septic for use in small superficial wounds.

Chemical appearance: Ferric alum appears as a white powder or crystalline. The crystalline and powder forms of the substance are soluble in water. However, it is not soluble in organic solvent such as ethanol. When in water, the solution appears clears and does not form a residue. Both of them are not toxic and do not catch flames. However, it can present an environmental hazard if spread in a large area. Chemical application and strengths: The compound contains trace amount of iron and lead and has a PH value of about 3.5. It can absorb water from the atmosphere; therefore, it should always be stored away from measures under a closed container. It should also be kept away from materials that may oxidize and lead to a darker color. Given that Ferric alum is powder that does not burn when it is exposed to fire, it is commonly used in firefighting foams.
