Synonymous with sodium silicate, pauline is an inorganic substance, an aqueous solution called aqueous glass, a colorless, turquoise or brown solid or viscous liquid. Sodium silicate is made by melting silica (quartz sand) and soda ash (or soil alkali) in a melting kiln, cooling and crushing, and its fuel is coal, natural gas, and gas.
The raw materials for the production of bubble alkali are quartz sand and soda ash, and the two are mixed in a certain proportion and sent to the reflective kiln, and the packaging is solid bubble alkali after quenching the water of the furnace after calcination at high temperature. Solid pauline is conducive to transportation and storage. The solid bubble alkali is dissolved into a liquid at a certain temperature and pressure, which is the liquid bubble flower alkali.
The raw material for the production of pauline contains a large amount of silica, which will produce a large amount of dust during the production process. In this environment, the dust is mostly ultra-micro state, improper protection, easy to cause damage to the respiratory system and lungs, and can even cause silicosis for a long time.
How to strengthen personal protection
First look at the national standards, in accordance with the National Bureau of Quality Supervision, Inspection and Quarantine, the State Standardization Administration issued respiratory protection products GB2626-2019 standards, the production of dust masks must obtain a production and operation license in accordance with the law, all dust mask production technical specifications must meet the corresponding standards. The standard stipulates the production and technical specifications of respiratory protective equipment, and has strict regulations on the material, structure, performance, filtration efficiency, appearance, respiratory resistance, detection method, product identification, packaging, etc. of the dust mask, and the material must be non-irritating to the skin, non-allergic, and the filter material is harmless to the human body; The structure of the dust mask should be convenient to use, etc.
