Last week, the non-ferrous metal market still showed a situation of falling more and more, and continued to warm up. Of the 10 non-ferrous products monitored by the business community, 5 showed an upward trend, 2 prices were flat, and 3 products fell. Due to the recent ups and downs in the market, downstream purchases are on-demand, and most of the wait-and-see, market sentiment and transaction volume have further declined. The year-on-year price changes did not change much, and the data was basically the same as last week.
The biggest gain last week was copper, which was the first in the range of 2.5%. Last week, the domestic spot copper price remained within the range of 64,500-66550 yuan/ton. Although the price of copper in the week was mainly based on the increase, the overall market turnover was general. In particular, after the domestic copper price rose to 66,550 yuan / ton on Thursday, the trade between traders was dull, and the willingness to receive goods downstream was weak. Many downstream are hesitant to buy goods, and there are fewer people chasing them. Although the price has fallen back on Friday, the overall replenishment has been sufficient in the early stage, and the market has not changed much. Although the recent copper price performance is strong, boosted by external disk and macroeconomic data, the domestic interest rate hike problem still has a certain degree of suppression on copper prices in the short term, and the high level may continue to fluctuate in the short term.
Last week, the performance of precious metal products was very different. Silver still showed an upward trend, while gold turned from ups and downs and became the biggest decline product this week. Due to high domestic inflation, the market’s expectation of the central bank’s interest rate hike this month has intensified and the dollar has continued to strengthen. It also led to pressure on the price of gold, which led to a decline in gold prices. But for the gold trend, the rate hike is now only the market speculation. Interest rate hikes also have strengths and strengths. Now inflation expectations are still high, and gold is still an undisputed fact in the long run.
Fan Yanxia, ​​an analyst at the non-ferrous metals business community, pointed out that under the external disk drive, favorable import data and market speculation, the non-ferrous metal market continued to pick up this week, but the overall increase was not large, and the market volatility intensified this week due to the ups and downs of the market. Aggravating the downstream wait-and-see mood, from the demand side, the driving force to continue to support the price rise is still weak, but the macroeconomic data is positive, there is still room for growth in the non-ferrous metals in the later period, and the demand situation in the short term still determines the market's rise and there is no lack of shock adjustment. .

Quaternary ammonium salt is also called quaternary ammonium salt.
Quaternary ammonium salt is similar to Inorganic Salt, easy to dissolve in water, and aqueous solution can conduct electricity. Mainly through ammonia or amine and halogenated reaction system, for example:
The quaternary ammonium salt exists in nature, many of which have certain biological activity, and some quaternary ammonium salt can be used as the phase transfer catalyst in drugs, pesticides and chemical reactions.
