Under the spread of the new crown epidemic, after Americans experienced life and death, they set off the largest "resignation wave" in history, and the number of resignations broke the highest record since statistics began in 2000. Since April this year, more than 4 million people in the United States have voluntarily resigned each month. In August, the number of resignations exceeded 4.27 million, and in November, it rose to 4.4 million. The operation of society is linked. The large number of departures in the United States has led to a large shortage of labor; and the shortage of a large number of labor has directly led to the supply chain crisis in the United States; the supply chain crisis has directly affected prices and prices in the United States. The economy has a direct effect on people's lives.
The economic downturn will affect the market demand for concrete foaming agent.
Lightweight foamed concrete, also known as foamed cement, is a lightweight porous concrete product made from foaming agent aqueous solution into foam, and then adding foam to the slurry made of cement-based cementitious materials, aggregates, admixtures, admixtures and water, etc., through mixing, pouring and natural curing.
1. With compressive strength and aging resistance: although the traditional chemical thermal insulation materials can achieve the effect of thermal insulation, their compressive strength and anti-aging properties have been unable to meet the requirements. Lightweight foamed cement can completely solve this problem. It is a substitute for traditional thermal insulation materials.
2. It has a good light weight: effectively reducing the load of the building.
3. Good sound insulation: the sound insulation of lightweight foamed cement is 5-8 times that of ordinary cement, which fully solves the problem of sound insulation in living space.
4. Good high temperature resistance: the suitable temperature of foamed cement can reach more than 250 ℃ and 300 ℃, while the benzene board will soften and chemical reaction will occur when the temperature is above 75 ℃.
5. Improve the stability and life of the insulation layer: the foamed cement insulation layer has a high stability and anti-aging performance, which effectively ensures that the indoor floor is flat and uncracked, and its service life is 5-10 times that of benzene board and 5 times that of perlite particles.
6. Good environmental performance: all additives of foamed cement are plant protein fiber and animal protein, which are non-toxic and harmless, while chemical thermal insulation materials such as benzene board and perlite particles can produce harmful and toxic gases at high temperature.
7. Good thermal insulation: the thermal conductivity is 0.08w/m.k, which is 20-30 times that of ordinary cement.
8. It has a good compressive strength: when the density is 350kg/m3, the 7-day compressive strength is 6 kg, and the 28-day compressive strength is 9kg/cm2.
9. The construction is simple: foamed cement is a mobile liquid transported by mechanical high pressure, the construction saves manpower and material resources, and the surface is smooth and smooth after solidification.
10. Good moistureproof: when heating, there will be no condensation around the warm water pipe, and there will be no split between the layers.
11. Good combination: the material of foamed cement is cement, and the combination of the upper and lower layers is very good, so that the ground will not form hollow and collapse.
12. The construction speed is fast.
13. Good integrity: a cast-in-place seamless and intermittent, and cast-in-place board and mortar layer can be completely combined to form a whole.
14. It has the function of impermeability: due to the porosity and integrity of foamed cement, the impermeability of foamed cement is more than 6 times higher than that of ordinary floor.
15. Fireproof: foamed cement is an inorganic material (cement), which will not burn, so it has good fire resistance. When used in buildings, it can improve the fire resistance of buildings.

Indonesia plans to increase the content of palm oil-based fuel in biodiesel from 30% to 35%, from B30 to B35, starting from July 20, a senior official from Indonesia's Ministry of Energy said this evening, according to Reuters.
Indonesia, the world's largest palm oil producer, imposed a three-week export ban in May to control domestic cooking oil prices, leading to an increase in palm oil stocks. At present, the authorities are considering reducing the export tax on palm oil to stimulate exports.
Indonesia's Ministry of Energy said that while implementing B35, the ministry will also launch road tests of B40 fuel. Indonesia's senior cabinet minister Luhut Pandjaitan estimates that if Indonesia implements B40, the domestic market may absorb an additional 2.5 million tons of palm oil.
A German government spokesman confirmed that Germany has always wanted Canada to release parts of the "Nord Stream 1" natural gas pipeline sent by Siemens for repair, and this request has received a "positive" response from Canada.
The "Nord Stream 1" natural gas pipeline is the main pipeline for Russia to transmit gas to Europe. At present, the gas output of " Nord Stream 1" has been reduced by 60% compared with the beginning of June, and this is an important time for Germany to store gas for the winter. The German government plans to increase its natural gas inventory to 90% of its gas storage capacity by November, compared with 62% now. Therefore, there is a great need for "Nord Stream 1" gas transmission to fill the inventory.
