On the 19th, the first photovoltaic industry development forum in Shanxi Province was held in Taiyuan. A number of experts from the photovoltaic industry in Japan, Australia and China gathered together to discuss the industry prospects and provide suggestions for the development of the solar photovoltaic power industry chain in our province.
The participating experts agreed that solar energy is the cleanest, safe and reliable energy source in the future. Developed countries are taking the development and utilization of solar energy as the main content of the energy revolution. The photovoltaic industry is increasingly becoming an international explosion after the IT and microelectronics industries. Development industry. The province's territory is full of light, the distribution of light energy resources is even, and the prospects for development and utilization of the photovoltaic industry are broad.
At present, the 300 kW solar photovoltaic grid-connected power station of the North University of China, the 80 kW solar power station of the China Coal Museum and the solar streetlights used in individual sections have achieved good results, but this is only the most basic start of the photovoltaic industry and solar energy utilization. stage. In the future, photovoltaic curtain walls, photovoltaic roof coils, solar thermal heating and building construction should be perfectly combined, and the energy consumption of buildings should be basically solved by relying on solar energy.
It is very important to control microbial activity in cutting fluid containers. Both bacteria and fungi can cause problems because they metabolize the components of the cutting fluid, resulting in the production of biofilm/mucus (large quantities of biofilm/mucus can exacerbate foaming problems and sticky surfaces) and secondary metabolites in the form of short-chain organic acids. The latter can result in a lower pH of the cutting fluid and an increased risk of corrosion. It is also important to note that high levels of bacteria and fungi can cause health problems for those operating the machines.
If the pH drops to less than 8.5, it may indicate bacterial growth in the cutting fluid. In such cases, we recommend measuring bacterial growth and replacing the cutting fluid if the test is positive.
Other signs of bacterial growth are a bad smell and fungal/bacterial film on top of the cutting fluid.
