Hydrogen peroxide, also known as peroxide, is a low-toxic substance, but if used improperly, it can still cause harm to the human body. Next, I will introduce you to the use of hydrogen peroxide and its hazards.

Comb grass is a characteristic plant that can be grown all over China. The oil processed from the seeds of comb grass is comb grass. Glycine max is a special medicine made from oil, which has extremely high medicinal value.

The classification of citric acid should be based on the number of crystal water contained, such as: anhydrous, monohydrate, and dihydrate. Anhydrous lemons can be obtained when the water content is controlled at a suitable ambient temperature during crystallization. acid.

Hydrogen peroxide is used for oxygen bleaching or one-bath production and processing of annealing, boiling and bleaching. Hydrogen peroxide is often added to the water. Hydrogen peroxide is relatively stable in weakly alkaline or neutral conditions, and in weakly alkaline conditions. The addition of hydrogen peroxide has strong oxidizing properties, and the presence of heavy metal ions leads to early catalytic decomposition of hydrogen peroxide, which not only causes damage to hydrogen peroxide, but also damages fibers.

The solid defoamer is generally added in the form of spraying, and the viscosity of the coating is relatively large. In this case, if the solid defoamer particles are relatively fine, it is very likely that the particles cannot be effectively dissolved, which will eventually cause a large amount of The precipitation material.

This product is a white powder with strong hygroscopicity. It is prone to deliquesce when exposed to the air and absorbs carbon dioxide to generate potassium carbonate.

Due to the various types of test reagents, general test reagents are classified into two categories: inorganic and organic, and special test reagents and dangerous test reagents are stored separately.

Sodium persulfate is a white tasteless crystal or powder, also known as high sodium sulfate. Sodium sulfate is stable at room temperature and decomposes gradually at high temperature.

Generally speaking, when the human body undergoes aerobic metabolism, glucose will be converted into pyruvate, which enters the tricarboxylic acid cycle to produce energy; at the same time, pyruvate produces lactic acid.

Acrylic paint is a one-component self-drying weather-resistant and anticorrosive paint made by advanced technology based on traditional acrylic resin and added with long-life chlorosulfonated polyethylene rubber, weather-resistant pigments and fillers, and weather-resistant additives recognized by China and foreign countries.

The shape of sodium persulfate is milky white crystalline powder, which is soluble in water, and can accelerate the dissolution in wet humidity and high temperature; it can be dissolved by ethanol and silver ions, and the solubility in water at 20℃ is 549g/L; sodium persulfate is also deliquescent , In humid air and high temperature can accelerate the dissolution of sodium persulfate, release oxygen and become sodium pyrosulfate.

Meta-xylene is an organic compound with a molecular formula of C8H10 and a molecular weight of 106. It is a colorless and transparent liquid with an odor similar to toluene. It is insoluble in water, but miscible in most organic solvents such as ethanol, ether and chloroform. Used as solvent, medicine, dye intermediate, perfume, etc.
