In October, the manufacturing PMI was 50.2%, down 0.6 percentage points from the previous month, and the expansion rate slowed down.In October, the manufacturing PMI hit a new low since March this year, but it is still 0.1 percentage points higher than February affected by the Spring Festival holiday factor, and is more than 50% for 27 consecutive months. In addition, among the 21 industries surveyed in October, th......[ Read More ]
polypropylene staple fiber can prevent the shrinkage crack of mortar and concrete; improve the toughness of concrete; enhance the anti-seepage and crack resistance of concrete; improve the impact strength of the wall; improve the peeling resistance of concrete; improve the impermeability Sexual, freeze-thaw; enhance the function of retaining tendons; prevent cracking of mortar and prevent crack propagation. Tens of millions of fibers are evenly distributed in the concrete, which plays a very good role in micro-reinforcing, so that the integrity of the structure is well maintained, and the stru......[ Read More ]
In recent years, international oil prices have continued to rise, rising from a low of $30/barrel to a four-year high of around $80/barrel. But this week, with Saudi Arabia’s consecutive voices saying that it will increase crude oil production from the existing 10.7 million barrels per day to 12 million barrels per day, international oil prices plunged sharply on Wednesday, and the NYSE’s December delivery was light. Crude oil futures closed at $66.43 a barrel, down 4.22%; London Brent crude for December delivery closed at $76.44 a barrel, down 4.25%."Kashupi incident" forced Saudi A......[ Read More ]
