can. Oil stains are lipids. Under alkaline conditions, fat can be decomposed. Acids are formed in the product. Acids can react with soda ash, which promotes the continued decomposition of lipids. The decomposition product is soluble in water, so the oil is cleaned up.

The effect of Yuanming powder and salt is a reason, that is, neutral salt electrolyte enhances the water holding capacity of AES and 6501. CMC is carboxymethyl cellulose, which is a dextrin whose principle of thickening is completely different from that of Yuanming powder.

A disperse dye is a dye that cannot be dissolved in an aqueous solution and is present in a suspension in a dispersed state. If Yuan Mingfen has more electrolytes, it will lead to a decrease in dispersing performance and a coloration on the surface of the fabric. Severe, even condensation and precipitation will occur, resulting in tar-like spots on the infected objects.

If there are no other non-volatile substances, the distillation method can be used to take the fraction, and sodium metabisulfite can not be distilled. For example, the alcohol solution contains sodium metabisulfite, which can be distilled and condensed to obtain an alcohol solution containing no sodium metabisulfite.

Direct method zinc oxide is produced from various zinc-containing minerals or impurities. When zinc oxide is reacted with coke, it is reduced to metal zinc by steam, and then oxidized to zinc oxide by oxygen in the air to remove most of the impurities. The zinc oxide particles obtained by the direct method are coarse, and the purity of the product is between 75% and 99.5%.The raw material of the i...

Sodium chloride has a low solubility in alcohol, and the polarity of ethanol is also less than that of water. It is weak in cooperation with solvated water of sodium chloride. Therefore, sodium chloride is difficult to ionize free ions in ethanol, but it is an ion after all. Compounds are not simple molecules, so they should be considered as ion pair forms. Because the ionic bonds are not saturate...

The difference between food grade and industrial grade base: 1. Biochemical and heavy metal indicators are inconsistent. Industrial 99% caustic soda can only be used for industrial purposes. Industrial alkali is mainly used in leather, paper, printing and dyeing, sewage treatment, stripping and other industries. Uses. Food grade base is mainly used for food processing container cleaning, disinfect...

A very important reason why salt has a dyeing effect on direct dyes is to reduce the charge effect during fiber dyeing. Cellulose fiber has a surface potential in a neutral or weakly alkaline dye bath, and generates a charge repulsion with the direct dye anion. After the electrolyte is added, a large amount of positively charged sodium ions are generated in the dye solution, and the charge anion i...

Sodium sulfite is a sulfite, which is a specific substance, and sulfite is a general term for a class of substances, and sulfite has calcium sulfite in addition to sodium sulfite.

Sodium sulfite has a high melting point and will not decompose or hydrolyze when it is evaporated to dryness. If it can be hydrolyzed, it will react, and sulfur dioxide will be reabsorbed by sodium hydroxide, so it will not be hydrolyzed. Sodium sulfite is reductive and reacts with O2 to form sodium sulfate upon heating.

One of the zinc sulfate grades, zinc sulfate can be divided into: industrial grade, chemical fiber grade, fertilizer grade (agricultural grade), feed grade, pharmaceutical grade, food grade, etc., according to their use.To achieve chemical fiber grade zinc sulfate, this level is not high, as long as it can be used for chemical fiber production, the most common level is medical grade.

Nitrate ions are not oxidizing under alkaline conditions. In this case, a metathesis reaction occurs, and the product is barium sulfite precipitated and sodium nitrate. When hydrogen ions are present in the solution, the hydrogen ions will combine with the nitrate to form nitric acid and become oxidizing, in which case the sulfite will be oxidized to sulfate. In the presence of hydrogen ions, nitr...

Yuanming powder is also called Glauber's salt, and its scientific name is sodium sulfate. This is an inorganic salt that is very close to the chemical nature of salt. It has two uses in printing and dyeing plants, one is a dyeing agent for direct dyed cotton. The other is a retarder for dyeing silk fabrics.

Generally, it is sulfide, COD, color, suspended matter, etc., but there are some differences in pollutants produced by different production processes, and the above-mentioned wastewater pollution caused by the sodium sulfide production process is generally removed by using iron salts.

Sodium sulfide does not catch fire when it meets water!Hazardous characteristics: Explosion may occur by impact or rapid heating. Decomposes in acid, releasing highly toxic flammable gas

Sodium sulfide does not react with sodium carbonate, but they react individually under acidic conditions.What is the product of reaction between sodium sulfide and sodium carbonate?

Molecular mass or molecular weight is the mass of a molecule. It is calculated as the sum of the atomic weights of each constituent element multiplied by the number of atoms of that element in the molecular formula. The molecular mass of small to medium size molecules, measured by mass spectrometry, determines stoichiometry. For large molecules such as proteins, methods based on viscosity and ligh...

Isomer is a molecule with the same molecular formula as another molecule, but with a different chemical structure. Isomers contain the same number of atoms of each element, but have different arrangements of their atoms.[1][2] Isomers do not necessarily share similar properties, unless they also have the same functional groups.

Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. It requires less water vapor to attain high relative humidity at low temperatures; more water vapor is required to attain high relative humidity in warm or hot air.

Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.

A mordant or dye fixative is a substance used to set (i.e. bind) dyes on fabrics by forming a coordination complex with the dye, which then attaches to the fabric (or tissue). It may be used for dyeing fabrics or for intensifying stains in cell or tissue preparations. As applied to textiles, mordants are mainly of historical interest because the use of mordant dyes was largely displaced by directs...
