68514-09-0 - Introduction
Sulfite liquors, also known as Sulfite liquors, are chemicals commonly used in paper and fiber manufacturing processes. They are mainly aqueous solutions containing sulfites such as sodium sulfite or calcium sulfite. The nature of Sulfite liquors is that it has a certain acidity and can react with oxygen to form sulfurous acid, which plays an antioxidant role.
The main uses of Sulfite liquors are:
1. Paper industry, as a bleaching and deinking agent;
2. Fiber manufacturing, as a chemical to dissolve and bleach fiber;
3. In the food industry, as a food additive, it is used for anti-corrosion and anti-oxidation.
A common method for preparing Sulfite liquors is to react sulfurous acid with water to produce a sulfurous acid solution. In the case of industrial scale, sulphite liquors can also be prepared by reacting sulphites with water.
Regarding safety information, you need to pay attention to the following points:
1. Sulfite liquors belong to acidic chemicals. When contacting, protective gloves, goggles and other protective articles should be worn to avoid skin and eye irritation;
2. Avoid inhaling the gas and vapor of Sulfite liquors, and the working environment needs to be well ventilated;
3. Avoid mixing Sulfite liquors with oxidants (such as bleach) to avoid harmful gas or fire accidents;
4. Sulfite liquors should be stored in a cool, dry, well-ventilated place, and avoid mixing with other chemicals.
Cooking liquors, spent, oxidized refers to the waste liquid that has been oxidized in the production process. These waste feed liquids are mainly derived from the cooking sequence in the wood pulp manufacturing process. Cooking liquors, spent, oxidized by nature are highly acidic and Oxidative.
The waste feed liquid is usually treated by a method such as neutralization or precipitation. In large-scale industrial production, the waste liquid can be precipitated and removed by adding neutralizers such as calcium oxalate. The treated waste liquid can be reused as fertilizer or for other purposes.
When handling Cooking liquors, spent, oxidized, you need to pay attention to the following security information:
1. Waste liquid with high acidity and oxidation, need to wear personal protective equipment, such as gloves, protective glasses, etc;
2. Waste liquid may release harmful gases in the process of treatment, so it is necessary to maintain good ventilation and avoid inhaling gas;
3. Waste liquid should be properly stored and disposed to avoid environmental pollution.
