Boric acid is actually the boron oxide hydrate (B2O3 · 3H2O. The specific gravity of 1.435 (15 ℃). Boric acid solubility in water increased with the increasing of temperature, and water vapor can be as volatile; in the solubility of inorganic acid in water solubility than in small. Heated to 70 ~ 100 ℃ gradually dehydrated to produce boric acid, 150 ~ 160 ℃ generation focal boric acid, boron anhydride is generated at 300 ℃ (B2O3).

Boric acid is toxic to the human body, oral effects of central nervous system.
The acid source is not itself is due to proton, electron deficient boron is atomic, can the hydroxyl ion and water molecule, and the release of protons. The electron deficient nature, adding polyhydroxy compounds (such as Gan oleyl alcohol and glycerin) to form stable complexes, in order to strengthen its acid.
Liaoning Pengda Technology Co. Ltd. (formerly known as Yingkou Pengda Fine Chemical Co., Ltd. was founded in 2004, is located in the east of Liaoning Yingkou Chinese). Through the unremitting efforts and the strong support of all staff of the boron customers, to meet the market demand, production of our company products for 4 consecutive years in the previous year on the basis of double speed continuous growth. Six BN accounted for domestic sales ratio of 1/4, anhydrous borax production accounted for the proportion of domestic sales of 1/2. 2010 at the national level in Northeast coastal industrial base to deliver the goods, investment of 65000000, the government subsidized loans 40000000 carefully to create a new boron as. We will join hands with deep processing products of boron brothers and the common development of enterprises, as China boron industry more the last new step, dedicate myself, go to the international market! The total area of 60000 square meters of new plant, a project has completed, investment 50000000 yuan, the workshop 4600 square meters, R & D center and 2500 square meters of office, the two phase is expected to start by the end of 2012 3, investment 40000000 yuan, the workshop 4000 square meters, R & D center and 2500 square meters of office. The establishment of Liaoning Pengda, creating the chemical industry and the monument forever forward.
Company is mainly engaged in the Six Party of boron nitride and deep processing products, boron amorphous (boron powder, two (three) of boron oxide, boron oxide superfine boron anhydride), anhydrous borax, soil fertilizer production. In 2011 through the ISO9001:2008 quality management system certification. Company constantly updated equipment, Belgium to introduce advanced equipment, products widely used in electronics industry heat conducting material, metallurgical lubrication and demoulding. Our company has the most novel spectral analyzer, particle size analysis can meet international standards. Anhydrous borax (sodium borate anhydrous four) based on the widely popular in domestic and exported to Europe, Southeast Asia and other regions, exports for 3 consecutive years, ranking first in china. Three oxidation two boron (boric anhydride) content is 99%, the minimum size can achieve two thousand orders, domestic only this one. At present our company total annual output value reached sixty million yuan, is expected in 2012 October after the production capacity will continue to increase to eighty million, the company in line with quality is of this, credibility is the soul of enterprise principles, to build the brand image of the boron.
Boron as companies adhering to the "efforts to create better value" business philosophy, integrity management, and constantly improve themselves and challenge. We always put customers first. We believe that: the development of customer development is the ultimate goal of company B, the highest customer satisfaction is boron Da company.
