Instructions for the use of various detergents?

Classification of household textile detergents

Washing products are mainly divided into two categories: one is fat (fragrant) soap; The second is synthetic detergent. Among synthetic detergents, washing powder accounts for about 2/3, liquid detergent accounts for about 1/3, and solid synthetic washing products are relatively few. In the field of textile washing, the most common are soap, granular or powdery washing powder and clear liquid jujube pulp liquid detergent. Soap is the sodium salt or potassium salt of various fatty acids, which is generally saponified by oil and alkali, and made by full boiling method, cooling method and carbonate method. There are some restrictions on the use of soap: First, in case of hard water, the washing effect is poor, and obvious dirt may remain. When washing textiles with hard water, soap will react with calcium ions and magnesium ions in the water to produce calcium soap and magnesium soap, which not only wastes soap, but also turns the color of textiles yellow and hardens the fabrics. Second, the universality is poor. Making soap requires a lot of caustic soda, which makes soap too alkaline and corrosive, and is not suitable for washing silk, wool fabric and some chemical fiber fabrics. Third, it may irritate the skin. The sodium hydroxide content of soap is usually high, which greatly enhances the alkalinity and corrosiveness of soap. On the contrary, human skin is generally in a weak acidic environment. When washing by hand, soap has great stimulation and damage to the skin, and the close-fitting clothes washed with soap also stimulate the skin, making people feel sticky and hot.

Professional detergent

Different from household detergents, professional detergents are an independent classification, mainly including hotel, hospital and hotel detergents, which are used in large washing industries such as laundry rooms. Including public facilities, textile industry, leather, food industry, vehicles, metals, optical glass, plastic rubber and other industrial cleaning agents. Surfactants commonly used in industrial cleaning agents: cationic surfactant/anionic surfactant/amphoteric surfactant/nonionic surfactant, and nonionic surfactant is commonly used in general low foam cleaning agents.

Dishwasher special detergent

1. Why do dishwashers use special detergents when washing? Because ordinary detergents generally produce foam when washing, the generated foam will make the water in the dishwasher overflow to the bottom plate of the dishwasher, which will cause the dishwasher to stop automatically and affect the operation and washing effect of the dishwasher. Special detergent is a non-toxic and low-foaming detergent produced according to national standards, which is suitable for dishwashers. At the same time, the special detergent has a very good ability to decompose oil stains, which can effectively decompose oil stains on the surface of tableware.

Second, dishwasher detergents are mainly divided into three types:

1. Dishwashing powder (washing powder) Function: Infiltrate and remove stubborn stains, such as burnt sauce, burnt cheese, oil stains and egg stains, and make dishes clean and shiny again. This function is the same as ordinary dishwashing, but the dishwasher must be dedicated, just like a good horse with a saddle. 2. Rinsing agent Rinsing agent is a weakly acidic detergent function: to prevent water stains and water marks.

3. The function of special salt: softening water quality. Most of the water in China is hard and contains many impurities. Long-term use of hard water will cause calcium precipitation inside the dishwasher, which is the same as the scale in the kettle at home. Dishwasher has a complicated internal structure, which is not as easy to clean as a kettle. It can only soften and purify water from the beginning. This is what salt does.
