2K Water Deflector Injection Mould The water deflector is between the windshield and the wipers,used to house the wipers, sprinklers and rainwater collection devices. The traditional sealing strip between the sink and the windshield is used to solve the sealing problem. Although the sealing strip is simple to install in the production process, there is a risk of the sealing strip and the windshield falling off, and the sealing performance can not be guaranteed. 2K Injection Part,Wind Deflector Part,Car Deflector Plastic Part,Wind Deflector Mould Taizhou Huangyan Xingtai Plastic Mould Co., Ltd. , https://www.xingtaimould.com
Extracting strontium from rare earth ore
Lijiu Cheng et al reported extracting scandium from the rare earth ores, to NaCl or NH 4 Cl scandium leaching from the mother liquor, pH 3 to 4, and extracted naphthenate, rare earth ions extracted into the organic phase, while leaving the scandium raffinate. However, Zhang Yi studied in detail the extraction of various rare earth elements by naphthenic acid, which indicated that the extraction started at pH 2.20, and the extraction was completed at pH 3.3. The pH 1/2 was only 2.84, which was smaller than other rare earth elements. The extraction order of various rare earth ions is Sc>Eu>Gd>Yb>Nd>Y>La, which is different from the extraction sequence given by Li Jiucheng ΣCe>ΣY>Sc. Yan Chunhua the like to HA-ROH- coal oil system, with a three-step cross-flow extraction obtained from only 0.04% of scandium-containing material of a rare earth-rich liquid by fractional scandium (containing about 15 ~ 30% Sc), crude scandium (Sc³99%) And high purity cerium oxide (Sc 2 O 3 /REO 399.999%), the total extraction yield is greater than 90%.
