泡沫或橡胶很有趣!您可以到处找到这些实用的东西。只是环顾四周找出多少泡沫或rubbers可以在眨眼之间找到!
For example, the bath sponge is made from foam!
另外,您可以在汽车,飞机,船只中找到各种泡沫,甚至可以在健身房中找到每种泡沫。
For example, when you want to do yoga, you must use the yoga mats, yoga rollers, aerobic steps, yoga block and other many things that you can’t even think!
Foams or rubber are used in the critical industries such as oil industry, Astronomy & military industry. That means the foams or rubbers must be reliable and produced in high-end technology.
我们在世界各地都有不同的泡沫生产商,但其中一些在这个行业中经验丰富且著名。德国和中国都是伟大的生产商,您可以从这两者那里购买一些泡沫!
They are also great exporters and more importantly in the foam industry they are precise & creative.

Foam producers are always looking on their quality & providing the best formula to keep themselves in a breathtaking competition between other serious competitors.
You need to know that all kinds of foams are widely used in every industrial product.
我们还可以说,在该生产系统的所有时间里,泡沫都是气泡的液体。
泡沫STRUCTURE
现在,我们想谈谈泡沫的结构。现在,您需要使用多尺度系统的泡沫和橡胶具有不同的结构。
这意味着一个比例就是气泡。您可以在主结构上看到不同尺寸的气泡。在大尺寸中,气泡紧密连接在一起,您还可以看到最小表面的数学问题称为“蜂窝”。
In the smaller scales, the linked bubbles are called “lamellae” which is outward from the connection points.
Also, in smaller scales you can see the liquid-air interface on the surface.
用一个词来说,橡胶或泡沫是通过将气体夹在液体或固体中而形成的物体。
If we want to speak about the structure of solid foams or solid rubbers, you must see them structure.
这种结构通常在气泡的流体中发展到多面体细胞。您需要知道包装的细胞具有非常不同的尺度和尺寸。

Foams or rubbers are both examples of dispersed media. In many ways, gas is present, so it divides into gas bubbles of different sizes (i.e., the material is polydisperse separated by liquid zones that may form films, thinner and thinner when the liquid phase drains out of the system films.
When the principal scale is small, i.e., for a very fine foam, this dispersed medium can be considered a type of colloid.
Rubber can also refer to something that is similar to rubber, such as quantum foam,polyurethane泡沫(泡沫橡胶),聚苯乙烯,XPS泡沫,酚类或许多其他泡沫或橡胶制造商是分散介质的例子。通常,存在气体,因此将其分成不同尺寸的气泡(也是材料是多分散的)。
Separated by liquid regions that may form films, thinner and thinner when the liquid phase drains out of the system films. When the principal scale is small, also for a high-quality foam, this dispersed medium can be considered a type of colloid.
Foam can also refer to something that is similar to foam, like quantum foam, polyurethane foam (foam or rubber), XPS foam, polystyrene, phenolic, or many other foam manufacturers.
The stabilization of a foam is caused by van der Waals forces between the molecules in the foam, electrical double layers created by dipolar surfactants, and the Marangoni effect, which acts as a restoring force to the lamellae.
Many things effect on foam stability. More importantly, we need to select the right surfactants. As mentioned earlier, surfactants are needed to foam bubbles and make the generated foam or rubbers more and more stable.

Surfactants that are good at foaming may not be good at reducing IFT.
我们有几个影响泡沫稳定性的因素。泡沫质量,表面活性剂类型和聚合物是我们的某种例子。
One of the most important aspects of foam fracturing is to keep the foam in motion. If the foam is not in motion, it will be unstable. When rubber’s moving has stopped, gravity will cause the free fluid in the foam to drain. This drainage can cause foam more instable.
泡沫排水速率将取决于许多因素,例如温度,液相的粘度和泡沫代理浓度。温度升高可能会导致流体粘度的降低。
Now we want to speak about Marangoni effect.
This effect depends on the liquid that is foaming being dirty. Generally, surfactants in the solution decrease the surface tension.
The surfactants also numerous together on the surface and form a layer.
泡沫:各种特性
为了使Marangoni效应发生,必须缩进泡沫。这种压痕增加了局部表面积。表面活性剂的扩散时间比大部分溶液的扩散时间更大。
So, the surfactants are less concentrated in the indentation.
Also, surface stretching makes the surface tension of the indented spot greater than the surrounding area. Consequentially, since diffusion time for the surfactants is large.
Marangoni效应有时间进行。表面张力的差异会产生梯度,该梯度促进了从较低表面张力到较高表面张力区域的流体流动。第二张图片显示了Marangoni效应发生后的胶片。
Being a multiscale system involving many phenomena, and a versatile medium, foam can be studied using many different methods. According to the different sizes & scales, experimental methods are diffraction ones, mainly light scattering methods at sub-micrometer sizes & scales.
根据该系统的连续,其大量特性可以通过光传递和电导法进行分类。尤其是声学,结构和散装之间的相关性更准确地证明了。
The organization between bubbles has been studied numerically using sequential attempts of evolution of the minimum surface energy either at random (Pott’s model) or you can choose the determination (surface evolver).
The evolution with time can be simulated using these models, or the bubble model (Durian), which according to the motion of every bubbles. You need to know that these specs can be tested again. You also can tell us your experience.
Observations in the structure can be made by shining the foam with laser light or x-ray beams and measuring the reflectivity between bubbles. Observations of the interlocking structure can be done with scattering among the neutron.
多个光散射的测量原理与垂直扫描相结合。
A typical light distributing (or diffusion) optical methods, multiple light scattering coupled with vertical scanning, is the most widely used technique to monitor the dispersion state of a product, hence identifying and quantifying destabilization phenomena. It works on any concentrated dispersions without dilution, containing rubbers. When light is sent between the sample, it is distributed by the bubbles.
The distribution intensity is directly proportional to the size and volume fraction of the dispersed phase. Therefore, local changes in concentration and global changes in size (ripening, coalescence) are monitored.

Foams applications
现在,我们想根据我们所说的结构来谈论橡胶或泡沫的应用。
当我们谈论液体泡沫时,您需要知道我们可以将液体泡沫用作强烈的阻燃剂。
For example, fire extinguishers are using the liquid foam to extinguish the fire.
The liquid foams having the very unique structure that you can see high specific surface area is exploited in the chemical procedure.
第二个类橡胶是固体橡胶or solid foams. They are lightweight with engineering cellular material. You need know that foams are mostly classified into the two kinds in their category.
第一个是闭孔泡沫,第二个是打开的电池泡沫。
打开的单元具有与互连网络相互关联的孔,它们相对较软。
在另一侧,封闭的单元格没有孔相互连接的孔。通常,它们的结构具有更高的抗压强度。
The closed cells are usually having better moisture absorption, higher dimensional stability & higher strength compared to closed cell foams or rubbers.
我们有特殊的闭孔泡沫,称为句法泡沫。
Foam, in this case meaning “bubbly liquid”, is also produced as an often-unwanted by-product in the manufacture of various substances.
For example, foam is a serious problem in the chemical industry, especially for biochemical processes.
Many biological substances, for example proteins, easily create foam on agitation or aeration. Foam is a problem because it alters the liquid flow and blocks oxygen transfer from air (thereby preventing microbial respiration in aerobic fermentation processes).
For this reason, anti-foaming agents, like silicone oils, are added to prevent these problems. Chemical methods of foam control are not always desired with respect to the problems (i.e., contamination, reduction of mass transfer) they may cause especially in food and pharmaceutical industries, where the product quality is of great importance.
Mechanical methods to prevent foam formation are more common than chemical ones.

What is foam faq
1.What is foam material
Foam or rubber (also known as cellular, sponge, or expanded rubber) refers to rubber that has been manufactured with a foaming agent to create an air-filled matrix structure. Commercial foam rubbers are generally made of either polyurethane or natural latex.
2.What is foam in chemistry?
Summary. A foam is a dispersion of a gas in a liquid prepared using a foaming agent, which in most cases consists of one or more surfactants. Foams can be prepared from two overall processes termed condensation and dispersion. This chapter discusses some applications of foam structures.
3.How is foam manufactured?
泡沫是通过使用吹剂在塑料混合物中形成气泡来制成的。泡沫制造是制造层压板或平板库存的连续过程,或者是通过切割或成型制造各种形状的批处理过程。泡沫有两种基本类型。
4。Is foam toxic?
根据美国环境保护署(USEPA)的说法,暴露于聚氨酯泡沫的某些主要成分(异氰酸酯)可能会引起一系列负面的健康影响,包括哮喘,肺部损伤和呼吸损伤以及损害以及皮肤和眼睛刺激。
5。可以回收泡沫橡胶吗?
