What are the Application of Small Cement Foaming Machine
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 foam generator?
What is the core component of the cement foaming machine
The foam generator, also known as the foam cylinder, is the core component of
the cement foaming machine. The foaming agent passes through it under pressure
to generate foam. Therefore, the proper design of its technical parameters
determines the foam quality, which is invisible from the appearance of the
cement foaming machine. The main factors of the foam generator are its
length-to-diameter ratio, the variety of filling materials, and the filling
volume. If its length-to-diameter ratio is too large, the foam tube is too long,
the air resistance is large, the foam is small, and the water content is small,
that is, the foam is dry and the output decreases. At the same time, the foam
wall is too thin and easy to break. However, if the foaming tube is too short,
the output is high, but the foam has a large water content and the quality is
degraded. Therefore, there is an optimal ratio between the length and the
diameter of the foam cylinder, which should be determined through a lot of
experiments. The second factor of the foam generator is the variety of filling
materials. When granular materials are added, the bubble diameter becomes
larger, and when fibrous materials are added, the foam becomes smaller. The
filling volume also has a great influence. Large filling volume will result in
high resistance, small bubble diameter, lower output, and low foam water
content; while filling volume will increase foam and output increase, but with
high water content.
Main application of small cement foaming machine
The small cement foaming machine is a cement product with unique technology
and good quality. It has many uses in construction engineering. It is mainly
used in floor heating and thermal insulation layers, roof thermal insulation
layers and thermal insulation walls. Small cement foaming machine is widely used
in: foam concrete cutting, lightweight wallboard, fire door core magnesium
oxychloride cement foaming and glass magnesium composite air duct production
line and other environmentally friendly foaming auxiliary equipment, with large
foaming volume, use Convenient and flexible.
The outstanding feature of this cement foaming machine is the low water
content of the foam produced, that is, the low density of the foam. The weight
of foam per liter can be controlled below 50g at room temperature, up to
The general foaming machine in the market has a large water content, and its
density is mostly 80-100g per liter. The water content of the foam is actually a
foaming agent solution that has not been foamed. The foam has a high water
content (that is, a high density), and its harm is great. One is that the
foaming agent solution that has not been foamed is wasted, increasing the amount
of foaming agent;
The second is that a large amount of water in the foam enters the cement
slurry, which reduces the density of the foamed cement. When the excess water
evaporates, it causes capillary pores, which increases the thermal conductivity,
increases the water absorption rate, and reduces the compressive strength, which
seriously affects the quality of the foamed cement. Therefore, foam density is
the first indicator of foam quality. The main factor that determines the foam
density is the performance of the foaming machine.

China's non-manufacturing purchasing managers index for March was released by the China Federation of Logistics and Purchasing and the Service Industry Survey Center of the National Bureau of Statistics today. An index of business activity for the non-manufacturing sector as a whole fell below 50 percent.
China's non-manufacturing business activity index was 48.4%, down 3.2 percentage points from the previous month. The new orders index was 45.7 percent, down 1.9 percentage points from the previous month, indicating a significant slowdown in the growth of supply and demand in the non-manufacturing sector from the previous month. In terms of sectors, the business activity index and new order index of transportation, accommodation and catering, culture, sports and entertainment, and tourism-related industries all declined significantly from the previous month.
