GOST 8429-77 sets strict requirements for the production and quality of borax 5-water, guaranteeing its compliance with industrial and technical standards. This standard regulates the physical and chemical parameters of the substance, including the content of the main component and permissible impurities, which ensures the stability of the product's characteristics. Compliance with GOST is a mandatory condition for manufacturers, as it guarantees the safety and effectiveness of its use in various industries.
The presence of a certificate of conformity confirms that the product has passed all the necessary tests and meets the declared quality standards. This is especially important for enterprises using borax 5-water in critical technological processes, where deviation from norms can affect the final result.
Borax 5-water is a multifunctional chemical compound produced in various grades for use in different fields of industry. Each grade has unique properties, allowing it to be used in specific technological processes. If you need to buy Borax 5, it is important to consider its grade, since the effectiveness of its application in a given field depends on it.
Borax 5, grade A, is widely used in metallurgy, ceramics and glass production. Its use helps improve the quality of finished products, providing the necessary physical and chemical properties of materials. Thanks to its characteristics, this grade has become an indispensable component in a number of technological processes.
Borax 5, grade B, is distinguished by a wide range of applications: from the production of enamels and glazes to use as a herbicide or flux component. In addition, it is part of brake fluids and other specialized products. Its versatility makes it in demand across various industries.
In addition to industrial use, Borax 5-water is used in the agricultural sector as a mineral fertilizer. It helps enrich the soil with beneficial trace elements, which has a positive effect on plant growth and yield increase. This makes it a valuable component in modern agriculture.
The health hazard is posed by boric acid, which is part of borax 5. This substance can cause severe irritation of the mucous membranes of the eyes, nose and respiratory tract, causing coughing, redness and inflammation. Prolonged contact or inhalation of dust may lead to chronic respiratory diseases. Ingestion of the compound poses a particular danger — even small doses can lead to acute poisoning, accompanied by nausea, vomiting, diarrhea and kidney damage. In severe cases, intoxication causes disorders of the nervous system, convulsions and even coma. Therefore, when working with borax 5, safety precautions must be strictly observed, personal protective equipment must be used, and direct contact with skin and mucous membranes must be avoided.
Borax 5-hydrate is a crystalline hydrate of sodium tetraborate with the formula Na₂B₄O₇·5H₂O. The number in the name indicates the water of crystallisation content, so the product differs from other forms of borax in composition and behaviour during storage or heating. When purchasing, it is important to check compliance with GOST 8429-77, the mass fraction of the main substance, boron oxide content, sodium oxide, sulfates, chlorides, iron and water-insoluble substances. These indicators affect batch stability and dosing accuracy.
Borax 5-hydrate dissolves in water, but the dissolution rate depends on temperature, crystal size, stirring and the required solution concentration. Under production conditions, the product is introduced into water gradually, achieving complete dissolution and absence of sediment at the bottom of the container. If the solution is used in a process with precise parameters, it is checked for clarity, concentration and the presence of insoluble particles. For a stable result it is important to use clean containers and not mix raw material from different batches unless necessary.
Borax 5-hydrate is stored in a dry, closed warehouse, in undamaged factory packaging and protected from moisture. If it gets wet, the product can clump, become contaminated and harder to dose when preparing solutions or dry mixtures. Bags are placed on pallets, separately from substances that could contaminate the batch or compromise its stability. For a wholesale buyer, preserving the labelling, quality certificate, production date and observing the guaranteed shelf life are important.
