How is the foam of the detergent created?

First of all, there is foam because of the surfactant in these cleaners.

It is also the main substance that can play a cleaning role. Common surfactants are composed of two parts, one is a hydrophilic (oleophobic) head group, and the other part is a lipophilic (hydrophobic) carbon chain, when cleaning the surface, the lipophilic carbon chain is combined with the grease substance, and then under the rinsing of water, the hydrophilic head base is combined with water, and the stain is washed off.

For bubbles, the basic structure is as shown below, which is equivalent to a sandwich similar to "surfactant-water-surfactant", separating the air on both sides. bubbles in thermodynamics.

It has a tendency to thin, rupture, and return to the liquid state, while the surface-active substances adsorb on the gas-liquid interface of the bubble to form a monolayer, which can prevent the film from becoming too thin and rupture locally, but evenly thinning as a whole, so the bubble will eventually burst. This property is known as film elasticity.

As for the relationship between foaming ability and cleaning ability, my personal understanding is that the ability to produce bubbles can only reflect the hydrophilic ability of the surfactant to a certain extent, but not the lipophilic ability of its carbon chain. Therefore, in the era of underdeveloped science and technology, the foaming ability of detergents reflects the amount of surfactant content in it, and the more natural foaming the content. Now, with the development of science and technology, there have been low-foam, or even non-foam-free surfactants (mostly achieved by changing the type of carbon chain, introducing multiple lipophilic groups, changing the position of hydrophilic head groups, etc., to change the molecular structure of surfactants), so the amount of foam can not fully represent the cleaning effectiveness of the detergent.

The reason for the degreasing of surfactants is that one end is bound to grease and the other end is combined with water; The reason for the formation of bubbles is that one end is combined with water, and the other end is in air and symmetrical on the inner and outer surfaces of the bubble, which increases the surface tension and makes the bubble not easy to burst. Then we can draw a very simple conclusion, for a surfactant molecule, once combined with grease, it is no longer easy to form a sandwich structure of bubble air surfactant water, because its hydrophobic group is already occupied by grease. If you think about washing your hair and washing your hands (especially when you wash your hair), if it is dirty, the shampoo will not foam the first time, and the shampoo will not foam after rinsing it off.

In other words, the phenomenon of foaming bubbles proves that the surfactant has been excessive, and there is no longer a large amount of grease left in the cleaned object. Therefore, we can use this phenomenon to determine whether to add more shampoo. So, the logical reasoning of bubble cleanness is inherently correct.

But it's not that the more bubbles you make (at this moment), the stronger the cleaning effect, but that the more bubbles you make, it proves that you have too much detergent (at this moment) and that you have washed it off. <>

The cleaner is mainly a liquid tile cleaner made of surfactants, fungicides, polishing agents, imported penetrating agents and unique brightness factors and other environmental protection technologies. It has strong detergent power, penetrating power, sterilization power, and polishing brightness. It can quickly and thoroughly clean the bottom of Wang-Qi Lijing Tile Cleaner (liquid) to remove stubborn dirt on the surface and crevices of various tiles. The unique penetration and polishing brightness factor can quickly remove lime scale, cement scale, caulk scale, rust, welding marks, aluminum scratches, metal scratches, black scale, mildew, scale, all kinds of paint, all kinds of glue, all kinds of heavy oil stains, etc., when it is coated on the surface of the cleaning object, it combines or melts with the dirt, but it needs running water to clean off its residue.

Water-saving cleaners can use their own characteristics to use less or no water to save water.

Dry ice cleaning is a process in which dry ice particles ejected at high velocity hit and clean the surface of an object. When the dry ice particles (3 mm in diameter) ejected at high speed act on the surface of the object to be cleaned, the sub-zero low temperature can first embrittle the dirt and then blow it off, achieving a cleaning effect similar to that of a scraper scraping off oil stains.

Microbial cleaning technology is a method that uses microbial cells to decompose and convert the dirt attached to the surface of the cleaning object into non-toxic and harmless water-soluble substances. The name of this type of cleaning agent is microbial catalytic detergent - enzyme. It can completely decompose all the dirt, and it is a veritable environmentally friendly green cleaning agent.

There is no need to wipe it, because the interior cleaner is flexible and will not cause harm to the interior, and wiping it with water will wet the interior and not easily dry.

Sour MilkExpired Sour milk, although inedible, is a good wood floor cleaner. Because of the sour milk lactic acid.

The content is increased, and the dirt can be removed, and the remaining nail Y product can be maintained. Pour the milk into the basin, stir well with twice as much water, then soak the cloth in the basin and wring it out.

Background:

Until the 20s of the 20th century, most people used soap to wash things. Soap is a highly effective stain remover. It can be inexpensively manufactured from readily available raw materials such as vegetable or animal fats.

However, soap also has certain drawbacks. It leaves a layer of scum after use, and it will turn white things yellow.

If there had not been the First World War.

People will probably continue to use soap. During the First World War, the Entente.

The blockade caused a shortage of oils and fats in Germany. Gunther and Hitzel, two chemists working for a major German chemical company, were tasked with finding an alternative to soap. In 1917, they created the first synthetic cleaner and named it"Nekal"。

Of course, most foam cleaners are corrosive and rely on dissolving stains to achieve the cleaning effect. In the future, it is recommended not to use foam cleaner, Yueneng is very good, not foam, I usually use this, send the picture to you to see.

Yes.

It is mainly used to clean IT peripheral hardware devices and digital products, such as computers, mobile phones, and digital cameras.

SLR, tablet, etc.

The technology that mainly uses nano surface active technology and ecological green formula for ecological antibacterial is 99% decontamination ability and is harmless to the human body and equipment.

Precautions for the use of foam cleaners1. Due to the cleaning force, it will cause the fading or color difference of individual leather or flannel, please be sure to test a small area before determining whether to continue to use when cleaning the surface of the object.

2. Keep away from children.

3. If it accidentally touches your eyes, please rinse with plenty of water immediately and seek medical treatment.

Foam cleaners are used in a wide range of applications. It is characterized by the combination of foam cleaning equipment, full foaming, so that 90% of the foam is air, and the chemical content is very small, but good steel is just used on the blade, these chemicals because of the light foam, just can be in contact with dirt for a long time, so as to give full play to the role of chemicals.

01 It's not.

When we use detergent to clean things, the surfactant first penetrates into the dirt, the surfactant envelops the dirt, and then rinses it with clean water, and the dirt is washed away. The foam produced when cleaning items is because the surfactant participates in the cleaning process, so the amount of foam is not a sign of the strength of the cleaning power, and the foam has nothing to do with the cleaning power.

In people's daily life, they often use various cleaning products to wash, dishwash, bath, etc. So, does the amount of foam have anything to do with the cleaning power? Is it true that the more foam, the better the cleaning power?

In fact, the amount of foam has nothing to do with the cleaning power, and the dirt and guess the trail is not washed off by the foam of the detergent. The main ingredient for cleaning dirt is surfactants. In simple terms, surfactants are ingredients that break down the surface tension of liquids.

For example, if a drop of water is placed on a bowl, the water will form a "small water ball", but if the water containing the detergent is dropped on the bowl, it will not form the "small water ball" mentioned above, but will spread out and become a pool of water. When we use detergent to clean things, the surfactant first penetrates into the dirt, the surfactant envelops the dirt, and then rinses it with clean water, and the dirt is washed away. When it comes to foaming when cleaning items, this is because surfactants are involved in the cleaning process, so the amount of foam is not a measure of the strength of the cleaning power, and the foam has nothing to do with the cleaning power.

No, the industrial cleaning defoamer is refined by a variety of special polyethers through a composite process, which has good defoaming and high shear resistance. Steel plate cleaning agent, general strong acid and strong alkali under high pressure cleaning, degreasing agent degreasing powder, alkaline aluminum degreasing powder, ordinary coating cleaning, degreasing powder, electroplating, stainless steel cleaning, high-pressure spray cleaning, spray grease decleaning, industrial water treatment, chemical cleaning and other processes can be used to defoam.

How to use: When using, add directly or dilute with water and working night to stir evenly to save the amount of use. The amount of use is determined according to the foam situation on site, and the amount of use is adjusted, and the scope of use is in, but it should also be based on the foaming degree of the defoaming system.

The diluted defoamer should not be left for a long time, if it is allowed to stand for a while, it is better to stir gently before use.

The so-called industrial cleaning refers to the process of removing the polluted layer or covering layer formed on the surface of an object due to physical, chemical or biological action in the process of industrial production, and restoring it to its original surface condition.

Fenggu Energy Saving Technology provides a kind of defoaming device and method that is widely used in various aspects of industrial cleaning - mechanical defoamer. The cleaning defoamer is an open physical defoaming equipment, which effectively meets the needs of customers for defoaming, defoaming and defoaming, and has become a new type of industrial defoaming weapon.

Hope it helps, hope!

Principle: 1 The local surface tension of the foam decreases and the foam bursts2 The defoamer can destroy the elasticity of the membrane and cause the bubbles to burst3 The defoamer can promote the liquid film to drain, thus causing the bubbles to burst4 The addition of hydrophobic solid particles can cause the bubbles to burst5 The solubilizing foaming surfactant can cause the bubbles to burst6 The electrolyte disintegrates the electric double layer of the surfactant and causes the bubbles to burst.

Relationship with foam: Defoamer is to eliminate foam.

This is simple, try it to know that the foam can be removed cleanly.

It's a common misconception that most people think that foaming is the function of detergents, but in fact, detergents only keep the foam from bursting, not because of it.

In fact, any kind of liquid will bubble due to the impact of the gas when it is shaken. It's just that in ordinary water, the gas bubbles produced by the impact immediately dissipate and burst. We feel that the upstream does not think that there is a blistering judgment.

For example, when we shake a bottle of water, we can actually see the foam, but in an instant, the foam is crushed and dissipated due to the contraction of the water's tension.

The main ingredient of detergent is surfactant, which has the effect of reducing the surface tension of water, that is, reducing the tensile force of inward contraction of water. In this way, the foam caused by the gas impact will not be crushed by the shrinkage of the liquid surface so quickly. So, we saw a lot of bubbles.

Therefore, the so-called bubble is just a form of gas wrapped by the liquid surface due to collision, and it is inherently transformed, nothing but a packet of air.
