If it is not the 22-day limit imposed by China's current price adjustment mechanism, it is expected that the domestic refined oil price will be reduced as soon as the crude oil change rate reaches -4% on Friday. The long price adjustment period has hindered the downward adjustment of oil prices. Therefore, the decline in domestic oil prices must wait until June 8.
According to Zhuo Chuang Information, as of yesterday, the rate of change of crude oil in the three places has reached -2.65%, and it is expected to reach -4% as soon as this Friday, meeting the price change of the domestic price adjustment mechanism. However, domestic oil prices will fall due to the need to cut prices from the last 22 working days, that is, on June 8. -4% is ahead of 22, highlighting the suspicion that the domestic refined oil price adjustment mechanism has hindered the decline of oil prices, and the public's hope for the reform of the price adjustment mechanism has once again increased.
According to estimates, the price adjustment range is 500-600 yuan / ton, when the window opens in 22 working days, the decline will reach about 7%. According to the conversion of 600 yuan / ton, 90#, 93#, 97# gasoline will be reduced by about 0.43, 0.46, 0.49 yuan / liter, and 0# diesel price will be reduced by 0.51 yuan / liter.
Lin Boqiang, director of the China Energy Economic Research Center at Xiamen University, believes that shortening the cycle is not the same as lowering oil prices, but shortening the current 22-day cycle will be effective when international crude oil prices fall.
Sodium Tripolyphosphate, also Food Grade Stpp, or Stpp Detergent Powder,is an inorganic compound with formula Na5P3O10. Stpp Sodium Tripolyphosphate is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. It is produced on a large scale as a component of many domestic and industrial products, especially detergents. Environmental problems associated with eutrophication are attributed to its widespread use in Water Treatment.
The majority of STPP is consumed as a component of commercial detergents. It serves as a "builder," industrial jargon for a water softener. In hard water (water that contains high concentrations Ethylene-Vinyl Acetate of Mg2+ and Ca2+), detergents are deactivated. Being a highly charged chelating agent, TPP5− binds to dications tightly and prevents them from interfering with the sulfonate detergent.
Because it is very water-soluble, STPP is not significantly Pvc Resin removed by waste water treatment. STPP hydrolyses to phosphate, which is assimilated into the natural phosphorus cycle. Detergents containing phosphorus contribute to the eutrophication of many fresh waters.
