Glutaraldehyde, as one of Amazon Chemicals main chemicals, plays a very important role in different kinds of steerilization aspects like oil exploitation fungicide, leather tanning agent, poultry, aquafarm sanitation, etc. This passage introduces four applications for glutaraldehyde.
1 Bactericide and fungicide
Glutaraldehyde is a quick-acting and broad-spectrum chemical bactericide. It can not only kill most bacteria, fungi, spores and viruses quickly and efficiently, but also does not corrode metal instruments, glass and plastic utensils. The toxicity is very low, so it is widely used in the disinfection and sterilization of medical equipment, food utensils, poultry, aquafarm and environmental sanitation. There are three milestones in the development history of chemical disinfectants. The first is formaldehyde at the beginning of this century. The second is ethylene oxide in the 1930s, and the third is glutaraldehyde after the 1960s.
2 Leather tanning agent
In the tanning industry, glutaraldehyde is an excellent tanning agent. The traditional tanning industry uses 50% potassium dichromate solution as the tanning agent, which is likely to cause the pollution problem of chromium-containing wastewater. Glutaraldehyde, as a tanning agent, can not only avoid such problems, but also make the product plump and soft with heat resistance, sweat resistance, soap resistance and other properties. Another feature of glutaraldehyde as a tanning agent is that it can interact with various proportion of mineral tanning agent, pickling agent, neutral salt compatible, has good performance in a wide pH range.
3 Oil exploitation fungicide
Oilfield water injection is a measure to increase crude oil production widely adopted by countries all over the world. By injecting surface water into the oil field, it can supplement the energy loss of the oil layer caused by oil discharge, maintain or restore the pressure of the oil field and increase the oil recovery rate. However, the temperature and the environmental conditions in the water injection process are suitable for the growth and reproduction of various types of bacteria, including aerobic bacteria and anaerobic bacteria. Glutaraldehyde is a non-ionic broad-spectrum bactericide, and it can tolerate salt and hard water. It can be used in combination with other agents. The bactericide compounded with glutaraldehyde, quaternary ammonium salts and other compounds can easily penetrate the protection formed by grease stains. It can kill bacteria under the protective layer, kill aerobic and anaerobic microorganisms, sulfate reducing bacteria and algae, and can remove the formed biofilms.
4 Cooling water treatment bactericide
The growth and reproduction of microorganisms in industrial cooling water will form slime in the water treatment system. They adhere to the pipe wall of the water cooler, affect the heat transfer effect on the water side and reduce the heat exchange efficiency. Since the 1980s, there has been an increasing number of factories using glutaraldehyde as a biocide in cooling water. Glutaraldehyde is a kind of high-efficiency and broad-spectrum bactericidal and algaecide with rapid action and long-lasting effect. It also has a certain effect on biological slime. In addition, glutaraldehyde is also used in air conditioning water treatment.
