The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring: Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the concrete foaming agent?
What is Foam Cement?
Foam cement is a kind of new light insulation material containing a large number of closed pores. It is made by firstly fully foaming the concrete foaming agent with mechanical methods, then evenly mixing the foam with the cement slurry, conducting cast-in-place construction, or mold forming through the pumping system of the foaming machine. Finally, after natural maintenance, it is formed.
It belongs to a kind of bubble-shaped adiabatic material. The outstanding characteristic is that the closed foam holes inside the concrete can make concrete light and heat preservative and insulate.
Advantages of Foam Cement Insulation Layer
Using foam cement to make roof insulation and external wall insulation, instead of polystyrene (benzene board) and other insulation materials, has incomparable insulation performance and structural layer adhesion performance, it is convenient for construction, environmentally friendly, efficient, time-saving, etc.
The practice has proved that foam cement has properties of good thermal insulation, heat preservation, sound insulation, light load, better than other light solid plastic extruded perlite, ceramsite, asbestos products, and other thermal insulation materials, with simple operation, high degree of mechanization, saving time, labor characteristics. Foamed cement can be transported by mechanical vertical pipeline, which shortens the working hours and improves the efficiency by 6~10 times more than other ways.
Besides, using foam cement as roof thermal insulation material, makes the adhesion between the heat insulation layer and the floor surface greatly improved.
In the past, most floor heating construction uses benzene board as the insulation layer, which cannot be well combined with the original base surface, but there is no effective adhesion, resulting in delamination, empty drum, cracking, etc. Using foam cement body as the thermal insulation layer, the foam cement insulation layer and the original floor of the small uneven base surface filling, and can grasp, grasp the formation of strong adhesion. After construction, the original surface layer basically reaches the required level, which brings convenience to the next process and ensures the overall effect of uniform thickness of the surface layer.
In addition, after using the insulation layer made by the original benzene board for 1-2 years, due to a long time of trampling, it is gradually sinking after bearing force, and it can crack up to 5~10mm. It will also cause damage to the heating pipe and water leakage. Using foam cement insulation layer can avoid such phenomenon, because the compressive strength of foam cement is higher than benzene board, the advantage is very obvious.
At the same time, using the benzene plate as the insulation layer, while heating with the temperature rise, polystyrene (benzene plate) will release residual body benzene and alkylene, etc. Especially in winter heating, doors and windows are closed, air mobility is very poor, and toxic gas cannot be replaced, which will cause certain harm to the human body. The roofing insulation made of foamed cement is not. The cement foaming agent is made of vegetable fatty acids, and the synthetic body is water-soluble. It is a safe environmental health product and will not cause harm to the human body.
Through the research of cement foaming technology, in terms of the heat insulation, adhesion, bearing, environmental health, and other aspects, the foam cement insulation layer is greatly superior to other heat insulation materials, especially suitable for large projects, high floors of convenient, fast on-site production construction. The foam cement insulation layer can also reduce the height of the floor, from the point of view of building structure design, can reduce the cost, and save the cost of the project.

Important discoveries have been made in the study of anticancer drugs inhibiting the growth of gastric cancer cells in my country. According to "Science and Technology Daily", a research report provided by Ai Jun and others from the Fourth Hospital of Hebei Medical University showed that seven anticancer drugs including cisplatin had obvious inhibitory effects on gastric cancer cells (BGC-823) in vitro. However, there are certain differences, and it is ideal to use a medium concentration for 48 hours.
