Lithium hexafluorophosphate, which has skyrocketed in the last round of lithium battery expansion, has continued to adjust. The latest price shows that the price per ton of lithium hexafluorophosphate is around 300,000 yuan, which is more than 30% more than the accumulated maximum of 400,000 yuan/ton in 2016.
According to the data, companies such as Polyfluoride, Tianci Materials, Bikang, Xintai Materials, Shida Shenghua, Yongtai Technology, BYD, etc. plan to increase the production capacity of lithium hexafluorophosphate from the end of 2015 or 2016. It is expected that lithium hexafluorophosphate will be ushered in the first half of 2017. A wave of peak capacity release.
In the electrolyte, the cost of lithium hexafluorophosphate accounts for about 70%. In the context of the price reduction trend has been set, the price reduction of lithium hexafluorophosphate will also drive down the price of electrolytes. Electrolyte leader New Qibang Securities Department said in a telephone interview that as new capacity is put into production, the tight supply of lithium hexafluorophosphate will be eased, prices will be lowered, and the corresponding electrolyte prices will also be lowered.
Although the electrolyte market is welcoming an inflection point, an electrolyte company executive believes that as the industry develops into a mature period, resources are continuously optimized and the industry concentration will gradually increase, and the situation of strong corporate strength will emerge. Only companies with technological leadership and supply advantages can keep up with the development of large-scale lithium battery plants, and then gain greater market share in the fierce market competition.
Tongue And Groove Face Flanges
The Tongue and Groove faces of this flanges must be matched. One flange face has a raised ring (Tongue) machined onto the flange face while the mating flange has a matching depression (Groove) machined into it's face.
Tongue-and-groove facings are standardized in both large and small types. They differ from male-and-female in that the inside diameters of the tongue-and-groove do not extend into the flange base, thus retaining the gasket on its inner and outer diameter. These are commonly found on pump covers and Valve Bonnets.
Tongue-and-groove joints also have an advantage in that they are self-aligning and act as a reservoir for the adhesive. The scarf joint keeps the axis of loading in line with the joint and does not require a major machining operation.
General flange faces such as the RTJ, TandG and the FandM shall never be bolted together. The reason for this is that the contact surfaces do not match and there is no gasket that has one type on one side and another type on the other side.
