"Jemaa Chemical" technological transformation promotes "green production"

The predecessor of “Jemaan Chemical” was the Longyou Pesticide Factory established in 1965. In the past, many wastes could only be disposed of and discharged. The environment was not polluted, and resources that could have been used were wasted.
“Before the technical reform, enterprises had run into production restrictions due to waste generated,” said Weng Jianxin. In the production of pesticides, aldehyde-containing acid effluents are produced because aldehydes are difficult to reuse and can only be stored there, and transferred to other companies or part of the biological treatment. Because of the limited storage capacity, when the waste liquid is full, it can only limit production. Now, the company has independently developed aldehyde-acid separation technology to separate and reuse aldehydes and acids in the waste liquid. Nearly 10,000 tons of aldonic acid waste liquid is used every year.
“Acetaldehyde separation” is an example of “Jemaan Chemical” turning waste into treasure. Around 2000, "Jemama Chemicals" carried out technological innovations at every stage of production, recycling waste that could only be discarded, and promoting energy conservation and emission reduction. According to the original process, the hydrogen produced during the production of glyphosate was directly discharged into the air. “Jemaa Chemical” developed a dehydrogenation technology that will recover 90% of the hydrogen and recover millions of cubic meters of hydrogen in one year. Several thousand tons of coal are saved; membrane technology has been developed to separate and concentrate glyphosate, reducing energy consumption and emissions; and developing sodium chloride extraction technology to extract sodium chloride from wastewater to improve water quality. Weng Jianxin deeply said with deep feelings that after the technical reform, the surrounding environment of the enterprise has improved, the villagers' opinions have been reduced, the energy consumption has been reduced, and the cost has been reduced accordingly.
Every technological transformation is an environmental baptism for employees. Technical equipment has gone up, and employees’ environmental awareness must also keep up. To this end, "Jemaan Chemicals" through various forms of environmental protection training, allowing employees to master new technologies, change ideological concepts, and strengthen environmental awareness.
Promote technological “green production” with technological advancement. At present, “Jemaan Chemical” has already filed 9 national patents for technology declarations, including the “method for separation and concentration of glyphosate in glyphosate mother liquor by membrane technology” and “dehydrogenation technology”. Five other technologies have obtained national invention patents, and the “membrane technology for separation and concentration of glyphosate in glyphosate mother liquor” has been promoted in the industry.

Wear Resistant Steel Plate

Wear-resisting Steel Plate is composed of low Carbon Steel Plate and alloy wear-resisting layer. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity of resisting external forces, and the alloy wear-resistant layer provides wear-resistant properties that meet the requirements of specified working conditions.

Wear-resisting steel alloy wear-resisting layer and base plate are metallurgical combination. By means of special equipment and automatic welding process, the high-hardness self-protecting alloy wire is uniformly welded on the substrate, and the composite layers are one to two or even more. In the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear, which is a significant feature of the wear-resistant steel plate.

The wear resistant layer of the alloy is mainly chromium alloy, while manganese, molybdenum, niobium, nickel and other alloys are added. The microhardness of carbide can reach above hv1700-2000, and the surface hardness can reach hrc58-62. Carbide alloy has a strong stability at high temperature, maintain a high hardness, but also has a good oxidation resistance, within 500℃ completely normal use.

The wear-resistant layer has narrow channel (2.5-3.5mm), wide channel (8-12mm), curve (S, W), etc. It is mainly composed of chromium alloy, while manganese, molybdenum, niobium, nickel, boron and other alloy components are added. With 40-60% carbide content, the microhardness can reach above HV1700 and the surface hardness can reach hrc58-62.
