Urgent need for sodium persulfate, fungicide, tert butyl hydrogen peroxide English version of MSDS

If the outer and inner packaging is damaged or mixed with impurities during transportation, the peroxide should be disposed of. When handling, it is necessary to understand the properties of peroxide before handling to avoid accidents. Here's how to deal with it:

Low-temperature activated peroxides, which cause decomposition at room temperature, are sprinkled on the ground to cause them to decompose naturally. It does not ignite during decomposition, but decomposition gas with flash flammability occurs, so be aware of the presence of smoke and fire in the surrounding area.

Respiratory protection: Filtering gas masks (half masks) should be worn when there is possible exposure to their vapors.

Eye protection: Wear chemical safety glasses.

Body protection: Wear polyethylene protective clothing.

Hand protection: Wear rubber gloves.

Others: Smoking is strictly prohibited on the work site. Practice good hygiene. **Contact: Remove contaminated clothing and rinse thoroughly with soapy and clean water**.

Eye contact: Lift the eyelid and rinse with running water or saline. Medical treatment.

Inhalation: Quickly remove from the scene to fresh air. Keep your airways open. If you have difficulty breathing, give oxygen. If breathing stops, artificial respiration is performed immediately. Medical treatment.

Intake: Drink plenty of warm water to induce vomiting. Medical treatment.

Fire extinguishing method: Firefighters must operate in an explosion-proof shelter. Fire extinguishing agents: water, foam, carbon dioxide, sand. Do not approach easily in case of fire. In the event of a fire near the material, water should be used to keep the container cool.

Tert-butyl hydrogen peroxide, an important branch of organic peroxide, is a volatile, yellowish transparent liquid, and is an alkyl hydrogen organic peroxide. It is mainly used as an initiator for polymerization reactions (such as polyvinyl chloride, polyacrylic acid emulsion after elimination of polymerization monomers, etc.); Crosslinker of unsaturated polyester, emulsion polymerization, sulfurization of natural raw rubber, diesel additives, paint industry, etc. It is also widely used as a raw material for the synthesis of other organic peroxides.

It is best not to leave it for too long, it will reduce the effect.

No, it should be said that the higher the concentration, the better the sterilization effect, but there are many factors to consider. For example, if the concentration is too large, it will affect human health, etc., and there is no need to be too high. People have calculated it after many experiments, and you should follow this standard.

No, it's mostly in terms of cost.

The fungicide can still be used just after the expiration date, and it will be invalid if it expires for too long.

Yes. The effect is a little smaller.

It still works, but it doesn't have much effect.

with high-grade fungicides.
