How to identify the quality of diatom mud? How to tell the difference between good and bad diatom mu

1.Water absorption.

The water absorption performance of diatom mud refers not only to the speed of water absorption of diatom mud, but also to see the water absorption limit value (the limit value represents the total amount of water absorption per square centimeter), the larger the water absorption limit value, the better the water absorption performance of diatom mud.

2.Adhesion.

Diatom mud material is a kind of wall material, which must have a certain strength and wear resistance. If the powder and slag are dropped, there must be a problem with the quality, indicating that the material is unqualified and the adhesion is not enough.

3.Look at the color.

Real diatom mud has a soft color, evenly distributed, and has a matte color with the effect of a mud surface. The fake diatom mud will show an oily surface, the color is too bright, there is a dazzling feeling, and it is easy to decolor and color after long-term use.

About the good and bad of diatom mud is introduced here, I believe everyone understands! Friends in need may wish to collect it, and they will use it in the future.

It is best to go deep into the factory, of course, as a consumer, you can understand it from the surface in a way that you can see, hear, and ask, and if you really want to investigate, you can test it through a special organization.

The most practical way to distinguish between good and bad diatom mud.

1. The eyes "see".

1. Look at the luster: diatom mud is a porous substance, and the porosity is thousands of times higher than that of charcoal products.

sound absorbs light, so the diatom mud wall should not reflect the fine frosted surface with the naked eye, such as.

If you find that the wall is as smooth as after painting, and there is a reflective phenomenon, it can basically be determined that it is counterfeit diatom mud, or an inferior product with very low diatomaceous earth content.

2. Look at the color: In the production process of diatom mud, in order to ensure that it will not be blocked due to the addition of pigments.

Small void, formal enterprises must use pure natural pigments, natural pigments are expensive, the color is soft, and it will not be very bright, so if you find that the wall color is not correct, or the color is bright, it must be added chemical pigments.

or the result of a tinted pink agent.

2. "Touch" with your hands

1 Stroke with your hands: Real diatom mud is soft to the touch and has a plush feel because of the diatom mud in order to prevent.

cracking, in the production of diatom mud wall covering, a certain proportion of plant fibers need to be added. If not, not.

After the anti-crack treatment, there may be a problem with the quality of the product.

2. Press with your nails: Diatom mud has moderate hardness, if it is hard with texture paint or soft with putty powder, then it is for sure.

Not real diatom mud.

3. Rub by hand: A good diatom mud dry rub will not obviously lose powder or color, if you rub it will lose powder, it can be basically confirmed.

There is a problem with the quality of the diatom mud, and there will be a lot of trouble in the future use.

3. "Spray" with water

The content of diatomaceous earth is an important indicator of the quality of diatom mud, and it is also the key to reflect the functionality of diatom mud.

When choosing diatom mud, you can do the water absorption experiment, high-quality diatom mud has strong water absorption, if it does not absorb water or absorb water.

Very little, indicating that the diatom mud void is blocked, so there is no functionality at all.

Weakly alkaline, can be reduced to mud for the second use of diatom mud with the natural properties of mud.

Diatom mud is known as the "breathing wall", how to distinguish the good from the bad?

Good diatom mud is characterized by high diatomaceous earth content, permanent decomposition ability of loaded photocatalyst, and natural weak alkali as raw material, which can be reduced into mud for secondary use.
