Oxalic Acid is an organic Acid Product with the IUPAC name ethanedioic acid and formula HO2C−CO2H. It is the simplest dicarboxylic acid. It is a white crystalline solid that forms a colorless solution in water. Its name comes from the fact that early investigators isolated oxalic acid from flowering plants of the genus Oxalis, commonly known as wood-sorrels. Oxalic Acid Dihydrate occurs naturally in many foods, but excessive ingestion of oxalic acid or prolonged skin contact can be dangerous.
Oxalic Acid 99.6% Min main applications include cleaning or bleaching, especially for the removal of rust (iron complexing agent). Its utility in rust removal agents is due to its forming a stable, I Want Oxalic Acid water-soluble salt with ferric iron, ferrioxalate ion. The cleaning product Zud contains oxalic acid.Oxalic acid is an ingredient in some tooth whitening products. About Sodium Hexametaphosphate 25% of produced oxalic acid will be used as a mordant in dyeing processes. Oxalic Acid Plant is also used in Titanium Dioxide bleaches, especially for pulpwood, and for rust removal and other cleaning, in baking powder,and as a third reagent in silica analysis instruments.

Analysis of the Status Quo of the Application of Smart Street Lamps in China in 2016
Urban road lighting is an important part of urban public facilities. With the advancement of urbanization construction, the number of urban road lighting street lamps is increasing, energy consumption is getting higher and higher, and power supply tends to be tight. In addition, the maintenance of urban lighting and high maintenance costs (manual control, street lighting inspections, etc.) have caused great difficulties for urban management. Urban road lighting is an important part of urban public facilities. With the advancement of urbanization construction, the number of urban road lighting street lamps is increasing, energy consumption is getting higher and higher, and power supply tends to be tight. In addition, the maintenance of urban lighting and high maintenance costs (manual control, street lighting inspections, etc.) have caused great difficulties for urban management. First, the street lamp stock is huge and stable growth As the main body of urban lighting, urban road lighting has accompanied the rapid development of China's urban construction and has achieved rapid growth. According to the statistics of the National Bureau of Statistics, from 2004 to 2014, the number of urban road lighting in China increased from 105.315 million to more than 30 million, and the compound annual growth rate exceeded 11%. The urban road lighting industry maintained a sustained and rapid development trend. Second, China's urban road construction to promote street lamp construction Urban road lighting project belongs to urban infrastructure construction, is part of the state's investment in public facilities construction. In recent years, with the continuous investment of the state in road construction, the length and area of ​​roads in China's cities at the end of the year have increased for many years. According to the National Bureau of Statistics, from 2004 to 2014, the length of roads in China's cities increased from 223,000 km to 336,000 km, with an average annual growth rate of 4.25%. Third, the continued advancement of urbanization, speeding up the infrastructure construction of street lamps As part of the construction of urban public municipalities, the construction of urbanization will directly promote the development of the urban lighting industry. In recent years, China's urbanization process has advanced rapidly, and the urbanization rate has gradually increased. In 2005-2015, China's urban population increased from 562 million to 771 million, and the urbanization rate increased from 42.99% to 56.1%, with an average annual growth of 2.45%. . China's urbanization will continue to advance. China's fourth, lighting energy consumption is huge, and efficiency needs to be improved. In 2013, the total electricity consumption of the whole society was 5.32 trillion kWh, a year-on-year increase of 7.5%. In 2013, road lighting used 29% of all lighting power consumption, accounting for 9% of the total electricity consumption in the whole society, ranking first in lighting consumption in various fields. From the current situation of the street lamp market, the management department needs to introduce more efficient management and energy-saving solutions to promote the scientific management and green energy conservation of urban lighting. At present, according to the statistics of the Road Lighting Professional Committee, 263 cities in 811 cities across the country have adopted the wireless three remote (remote control, shaking letter, telemetry) intelligent control system. With the widespread use of next-generation information technologies such as the Internet of Things, next-generation Internet, and cloud computing, smart cities have become an inevitable trend. As an important part of the construction of smart cities, smart street lamps have huge space for future development, and the intelligent transformation of street lamps is imperative. The investment in urbanization will continue to increase. Therefore, the state will continue to invest in infrastructure construction such as urban road lighting.
