What is Borax Dm?

Borax Dm is the condensation of natural borax Borax processed as well as improved. Borax is developed in the completely dry deposits of boron salt lakes, and also there are likewise salt-forming soils in dry areas. China is the very first nation to discover borax, and also borax was exported as early as 1563 AD. The salt lake sedimentary deposit near Lhasa, Tibet is among the renowned Borax Dm origins on the planet. There are numerous salt lakes in Qinghai Qaidam as well as various other areas in China. Borax Dm is a very vital heat-clearing as well as purifying astringent in conventional Chinese medicine. It has an excellent effect on acute throat, gingival swelling and also discomfort, and also otitis media. Borax is the transliteration of the Latin word Boraium. In ancient China, it was called “borax”, “pensha” or “Pengsha”, as well as the noise is extremely comparable. Borax in the very early East and West came from the same source – Tibet. Because Flavor Taizong married Princess Wencheng to Tubo King Songtsan Gampo, the inland as well as Tibet have actually strengthened exchanges and exchanges have actually come to be closer, as well as Tibetan borax has actually been imported right into the inland. Alchemy in the Tang Dynasty discussed borax in “Huangdi Jiuding Shendan Jing Jue”, “Taigu Tudui Jing”, “Jinhua Yuye Dadan”, “Taidong Lianzhenbaojing Jiujindan Miaojue”, “Zhenyuan Miaodao Yaolue” And so on. As a clinical item, it was first taped in “Nihua Zhujia Materia Medica” (around 970), which is roughly the like the earliest record of Borax Dm in the West. Borax, which was first introduced to the West, was a product of Tibet, and after that reached Western Europe via India, Constantinople and also Venice. The interaction between Tibet and the landmass is commonly blocked. In the 13th as well as 14th centuries, Tibetan borax was once imported into the landmass by means of Arabia by sea. This incident was mirrored in Zhao Rushi’s “Zhufan Zhi” in the Southern Tune Empire. The areas where borax is generated in modern China consist of Tibet and the salt lake in the Qaidam Basin of Qinghai.

Borax Dm Uses

Borax Dm can be used as a filler for washing powder and soap, as well as a raw material for manufacturing optical glass, enamel and enamel, as well as artificial gemstones and welding powder. After refining, it can be used as a heat-clearing and detoxifying medicine. It is cool in nature, sweet and salty in taste, and can cure sore throat, dental malnutrition, aphthous ulcers, and nebula.

Borax Dm becomes a colorless glass-like substance when melted, and is used to manufacture special optical glass. It can dissolve some metal oxides in the molten state, and show characteristic colors according to different metals. For example, when cobalt oxide is dissolved, it is dark blue due to the formation of Co(BO2)2, Cu(BO2)2 is blue, Cr(BO2)3 is green, MnO2·2B2O3 is purple, etc. Therefore, in analytical chemistry, borax beads can be used to identify metal ions. This property is also applied to the enamel and glass industries for glazing or coloring; also for artificial gemstones. Borax Dm is used as a flux when welding metals to remove oxides from metal surfaces. The aqueous solution of borax is alkaline and can be used as a filler in soap and washing powder. Medically used as an antiseptic. In traditional Chinese medicine, it is used as a heat-clearing and detoxifying medicine. In the chemical industry, it is the raw material for the manufacture of a series of boron compounds. The borax solution is used as a plant fertilizer. The leftovers of borax production (magnesium hydroxide and borax mother liquor) can be reacted with sulfuric acid to obtain a mixture of boric acid and magnesium sulfate, that is, boron magnesium fertilizer. Borax Dm is also a raw material for boric acid production.

Production Method of Borax Dm

In the carbon-soda method, the pretreated boron ore powder is blended with sodium carbonate solution as well as also responded in the carbonizer. The quantity of sodium carbonate consisted of is 105% to 110% of the scholastic amount. The carbonizer is warmed up by a jacket, the reaction stress is managed at 0.5-0.6 Mpa, the temperature is 130-135 ° C, the response time is 13-15 hours, as well as the co2 focus is 25% -30%. The purified kiln gas can be used right.After carbonization, the slurry is filteringed system to remove residues, countercurrently cleaned, and also the acquired clear service is focused (if the focus of the solution after countercurrent washing meets the needs, no focus is required), cooled as well as crystallized, centrifuged, and also dried to obtain the completed product of Borax Dm. That
2( 2MgO · B2O3)+ Na2CO3 +2 CO2+ Xh2o → Na2B4O7 +4 Mg · 3CO2 · Xh2o. The pressurized alkaline hydrolysis technique mixes the pretreated boron ore powder with sodium hydroxide service (the quantity of sodium hydroxide is 160% to 200% of the academic quantity), and also warms and also pressurizes it in an alkaline hydrolyzer geared up with a stirrer to decay it, The response pressure is 0.4 Mpa, the response time is 6-8h, the slurry after alkaline hydrolysis is filtered and also countercurrent cleaned with a blade vacuum filter, and then carbon dioxide is passed through for carbonization. The carbonized liquid is then taken shape by cooling down, divided and also dried to get the ended up item of Borax Dm. That.
2MgO · B2O3 +2 NaOH+ WATER → 2NABO2 +2 Mg( OH) 24NaBO2+ CO2 → Na2B4O7+ Na2CO3.

Physical Properties of Borax Dm

Borax Dm is the sodium salt of boric acid, the basic name of salt tetraborate, which is a boron-containing mineral. According to the amount of crystal water, it can be split right into 3 types: decahydrate borax, pentahydrate borax and also anhydrous borax.
( 1) The chemical name of borax decahydrate is sodium tetraborate decahydrate, the molecular formula is Na2B4O7 · 10H2O, as well as the molecular weight is 381.37. It is colorless translucent crystal or white crystalline powder, odorless, salty, thickness 1.73 g/cm3, melting point 75 ℃. In completely dry air, it can slowly shed water and end up being weather-beaten. When warmed to 300-400 ° C, all crystal water will certainly be shed as well as transformed right into anhydrous sodium tetraborate Na2B4O7. Soluble in water as well as glycerin, insoluble in alcohol. 878 ° C melting right into a glass-like compound.
( 2) The chemical name of borax pentahydrate is salt tetraborate pentahydrate, the molecular formula is Na2B4O7 5H2O, the molecular weight is 291.29, it is a white crystalline powder, the density is 1.815 g/cm3, when heated up to 122 ° C, it loses crystal water as well as becomes anhydrous Salt tetraborate.
( 3) The chemical name of anhydrous borax is sodium tetraborate, the molecular formula is Na2B4O7, the molecular weight is 201.22, it is white crystal or glass body, as well as there are 2 types of α and β: α orthorhombic crystal, melting point 742.5 ℃, thickness 2.28 g/cm3, β Orthorhombic crystal, melting point 664 ° C, density 2.75 g/cm3, solid hygroscopicity, soluble in water, gradually soluble in methanol, as well as can form a remedy with a concentration of 13-16%. Along with heat resistance, water resistance and also acid resistance, borax additionally has solid liquifying power. Borax Dm turns white as well as expands after home heating, as well as ends up being a clear glass round in which metal oxides can be liquified to restore the original color of the metal. This is the well-known borax sphere reaction. Borax can be made use of in the manufacture of capacitors, in numerous glass items, and in the ceramic market as a polish. It is made use of as antifreeze as well as anticoagulant in mining as well as metallurgical market, and also as electrolyte additive and welding representative in nonferrous steel industry. Additionally, it is made use of in the manufacture of preservatives, herbicides, dirt fungicides and also borides.
