Does caustic soda for drains really work for unblocking drains?

Yes, Caustic soda  can unclog the sewer, but caustic soda and hot water need to unclog, the caustic soda  and 60 degrees of hot water mixed evenly, and then poured into the sewer, caustic soda and hot water combined will gradually heat up, can be dissolved in the sewer grease clothes, sewer can be unclog.

Sodium hydroxide, inorganic compound, chemical formula NaOH, also known as caustic soda, caustic soda, caustic soda, caustic soda. Sodium hydroxide is highly alkaline and corrosive. It can be used as acid neutralizer, masking agent, precipitator, precipitation masking agent, color agent, saponification agent, peeling agent, detergent and so on. It has a very wide range of uses.

About caustic soda

Caustic soda has a strong base and has a strong hygroscopic property. Easy to dissolve in water, when dissolving heat, water solution is alkaline, there is a sense of slippiness; Highly corrosive, corrosive to fiber, skin, glass, ceramics and so on. Reaction with aluminum and zinc, nonmetallic boron and silicon to produce hydrogen; Disproportionation reaction occurs with halogens such as chlorine, bromine and iodine. Neutralize with acids to form salts and water.

Toxicological information

Sodium hydroxide is moderately toxic. Its dangerous characteristics are: in contact with water and steam a large amount of heat release, the formation of corrosive solution. Neutralizing reaction with acid and exothermic. It is highly corrosive. Combustion (decomposition) products: May produce harmful toxic fumes. Its invasion route is: inhalation, ingestion. Its health hazards are: strong irritation and corrosion. Dust or smoke irritates the eyes and respiratory tract and erodes the nasal septum; Direct skin and eye contact can cause burns. Ingestion can cause gastrointestinal burn, mucous membrane erosion, bleeding and shock.

application

Sodium hydroxide is mainly used in paper making, cellulose pulp production, soap, synthetic detergent, synthetic fatty acid production and animal and plant oil refining. Textile printing and dyeing industry used as cotton desizing agent, refining agent and mercerizing agent. Chemical industry for the production of borax, sodium cyanide, formic acid, oxalic acid, phenol and so on. The petroleum industry is used to refine petroleum products and in oilfield drilling mud. It is also used in the surface treatment of alumina, zinc and copper, as well as in glass, enamel, tanning, medicine, dyes and pesticides. Food grade products used in the food industry as acid neutralizer, can be used as citrus, peach and other peeling agent, can also be used as empty bottles, empty cans and other containers of detergent, as well as decolorizing agent, deodorant.

Sodium hydroxide used as a basic reagent, can be used as a neutralizer, with masking agent, precipitating agent, precipitating masking agent, a small amount of carbon dioxide and water absorbent, thin layer analysis of ketone sterol color agent, etc., widely used in the manufacture of all kinds of sodium salt, soap, paper pulp, finishing cotton fabric, silk, viscose fiber, rubber products regeneration, metal cleaning, electroplating, bleaching, etc.
