Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China. For China, we should keep to the dynamic zero-out and gradually open up."
However, "dynamic zero clearance" is not the pursuit of complete "zero infection". As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.
The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy. The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.
As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many concrete foaming agent.
Overview of concrete foaming agent:
Foam liquid concentrate is a hybrid formula that uses the performance of the protein-based products and combines them with the agility of the straight synthetic products.
The TR-B (foaming agent) can be mixed with cement slurry to produce lightweight porous concrete. Dilute TRB (foaming agent) with water, isolate it from the foam machine to obtain foam, and mix the foam with cement and gypsum mortar to obtain an insulating lightweight structural element.
Parameters of concrete foaming agent:
| Item | Parameter |
| Apperance | Brown liquid |
| Content | 40% |
| Usage amount(kg/m3) | 0.75-1.25 |
| Foaming multiple | ≥30 |
| Bleeding rate(ml) | 27 |
| Storage method | Store in a cool, dark place to prevent freezing and high temperature. |
| Safety | Non-toxic, non-corrosive, non-combustible, free of formaldehyde, ammonia, heavy metals, halogen |
Application of concrete foaming agent:
Lightweight insulation concrete production
Insulation lightweight block, brick, wallboard production
Heat and sound insulation floor
Non-load-bearing wall panels
Cement or gypsum board
Fill soil to prevent landslides
Underground drainage filling
Deicing under bridges and roads
Filling of tunnels and shafts
Production of thermal insulation lightweight concrete with polystyrene foam particles
Pearl Rock Cream Mix
Production of lightweight insulation floor and wall in steel structure system
Single-story building load-bearing wall
The advantage of concrete foaming agent:
1. Based on nature, there is no harmful effect on the environment.
2.The high bubble surface membrane has strength
3. In the case of foam increase, the surface charge has the ability to distribute.
4. Antimicrobial agent effective against mold in concrete
5. Foam density is adjusted between 80 and 95 g/L
6. Concrete density 115kg/m3 -1600 kg/m3 needs to be adjusted
7. The resulting pores provide high insulation for the concrete
8.Concrete mixing time has no volume loss
9.Minimum volume loss during pumping
10. Used with all kinds of cement
11.It reduces the setting time of concrete. Air temperature 25°C Molding time 5 hours
12. Stable foam remains upright for about 6 hours
Package of concrete foaming agent:
25kg/barrel, 200kg/barrel

Researchers at the Centre for Translational Atomic Materials at Swinburne University of Technology, Melbourne, Australia have developed a new graphene film that absorbs more than 90% of sunlight while eliminating most of the infrared thermal emission losses, a highly efficient A solar-heated metamaterial capable of rapidly heating to 83 degrees Celsius (181 degrees Fahrenheit) in an open environment with minimal heat loss. Proposed applications for the film include thermal energy harvesting and storage, solar thermal power generation, and seawater desalination.
