In-house product representative product cleaning mechanism

Main component: About the function of glycol solution

Cleaning is the removal of unwanted substances from the surface.

Dirt adhesion is relatively strong from very strong covalent bonds

It can range from weak van der Waals interactions.

To perform cleaning, use more energy than this adhesive force.

Need to add.

The cleaning mechanism is dissolution / replacement and dispersion.

There are chemical reactions and mechanical peeling.

Dirt is classified into liquid stains and solid stains.

The most common liquid stains are due to oils and fats.

More than 0.5 micron for individual stains

In the case of size, usually due to capillarity with oily stains

Therefore , it is stuck.

Therefore, cleaning oily stains will also remove individual stains.

Molecular weight of surfactant

Eco-sarasa has a small molecular weight

Figure 2: Effect of reducing surface tension by glycol ether in aqueous solution (25 ° C)

As described above, from the dissolution mechanism of dirt removal

Can also explain that dissolving power is important.

Further, penetrates removed dirt, is dispersed in the al

For that purpose, low surface tension is indispensable.

Glycol ethers compared to surfactants

This is included because the molecular weight is small.

"Eco Sarasa" is only a conventional surfactant

Dynamic surface tension is lower than the inclusive formulation.

The lower the dynamic surface tension, the more between liquid and dirt

Interface formation will occur quickly.

Glycol ether is a hydrophobic oil and dirt

Also works as a coupling agent that makes water compatible

Prevents reattachment after pulling out dirt.

It is a product that was in an era when awareness of hygiene management was required.
