How to distinguish the good from the bad of diatom mud? How to distinguish the quality of diatom mud

In fact, it is not easy to identify: 1. Look at the water absorption performance: 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. Look at 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.

For wall materials, the country has a relatively strict standard - more than 1,000 times of continuous scrubbing, only to meet this standard, this wall material can be said to be in line with the standard in adhesion. 3. Look at the fire performance: the fire performance of diatom mud materials generally must meet the national B-level standards formulated by the state before it can be passed.

4. Look at crack resistance: as a wall decoration material, crack resistance is also one of the most important indicators, just imagine, if cracks and cracks appear after slight vibration wall decoration, it will definitely have a significant impact on the overall wall. 5. Formaldehyde adsorption performance:

Most customers confuse water absorption with adsorption gas. In fact, high water absorption performance does not mean that the ability to adsorb toxic gases is also high, for example, loess has the ability to absorb water, but there is no ability to adsorb formaldehyde. 6. The content of diatom mud:

The content of diatom mud can not be absolutely said to be the worst of the diatom mud material, but also depends on the processing and production process of each manufacturer, for example, a stone does not have much water absorption capacity, and it can absorb a large amount of water by grinding it into powder alone. Therefore, the content of diatom mud is only an index, and the fineness of the particles, the temperature of sintering, the fineness of the coarse powder processed and the content of diatomaceous earth itself all determine the quality of diatom mud.

Look**, fake diatom mud is cheaper than real diatom mud, so, dear friends, don't be attracted by the so-called low**, it is very likely that it is a big trap, we must not covet that little bit of cheapness.

Looking at the color, the color of the real diatom mud is relatively soft and matte.

Try the feel, the master of Sikoku Huacheng diatom mud told everyone that the texture pattern made of real diatom mud is more delicate and generous, with a strong sense of art; Fake diatom mud generally feels very rough to the touch, and it is not suitable for any texture pattern.

Look at the water absorption, diatom mud has a strong water absorption, real diatom mud will quickly absorb water, and at the same time exude a faint earthy fragrance, if it is a counterfeit product does not have these phenomena.

Basic characteristics of high-quality diatom mud:

1. The material itself is inorganic, does not contain formaldehyde, and can be fed with goldfish with construction powder, which is non-toxic and harmless.

2. The diatomaceous earth content is more than 30% to have the real ability to adsorb formaldehyde.

3. Only those containing photocatalysts will have long-lasting purification ability.

4. The color is mineral composite color, warm and elegant, suitable for home decoration.

The diatomaceous earth content is high, the permanent decomposition ability of the photocatalyst is loaded, and the raw material is a natural weak alkali, which can be reduced to mud for secondary use.

Advantages: Diatom mud itself does not have any pollution, is natural, and has a variety of functions, which is incomparable to traditional coatings such as latex paint and wallpaper. There is no need to move when decorating with diatom mud, because there is no smell in the process of building diatom mud, which is pure natural and easy to repair.

Purifies the air and eliminates odors.

Disadvantages: The strength of the surface of diatom mud is relatively low and cannot receive a relatively large impact.

1. Natural weak alkali. 2. It can be reduced to mud. 3. It feels good. 4. The color is a natural composite color inorganic mineral pigment. 5. It has the ability to purify indoor air for a long time. Dr. Mud Diatom Mud has the answer for you.

To distinguish the quality of diatom mud, you can scrub it with a damp rag. If it is a good diatom mud, it can withstand scrubbing with a wet rag, and if it is an inferior diatom mud, there will be powder or color fading after scrubbing.

How to judge the quality of materials, you can refer to the common quality inspection report, harmful substance detection, formaldehyde purification rate, physical performance test In addition, you can also use small samples through some small experiments to identify the play of diatom mud in some functions.

1. Look at the luster: diatom mud is a porous substance, the porosity is thousands of times higher than that of charcoal products, and it has the function of sound absorption and light absorption, so the diatom mud wall should not reflect the fine frosted surface with the naked eye, if you find that the wall is as smooth as after brushing paint, and there is a reflective phenomenon, it can be basically determined that it is a fake diatom mud, or an inferior product with very low diatom earth content.

2. Look at the color: in the production process of diatom mud, in order to ensure that the tiny voids will not be blocked due to the addition of pigments, regular enterprises must use pure natural extracted pigments, natural pigments are expensive, the color is soft, and they will not be very bright, so if you find that the color of the wall is not correct, or the color is bright, it must be the result of adding chemical pigments or pastels.

3. Stroke with your hands: real diatom mud feels soft and has a plush feeling, because in order to prevent cracking, diatom mud needs to add a certain proportion of plant fibers in the process of producing diatom mud wall materials. If it is not stated that it has not been cracked, there may be a problem with the quality of the product.

4. Press with your nails: diatom mud has moderate hardness, if it is hard with texture paint or soft with putty powder, it is definitely not real diatom mud.

5. Rub by hand: good diatom mud dry rubbing will not obviously lose powder or color, if you rub the powder, it can basically be determined that there is a problem with the quality of diatom mud, and there will be a lot of trouble in the future use.

6. "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.

7. "Burn" with fire, diatom mud is a pure natural functional interior wall coating, without adding any chemical reagents, if chemical reagents are added, the holes of diatomaceous earth will be blocked two-thirds, and the quality of diatom mud will also decline. High-quality diatom mud will not burn with fire, and it will not emit black smoke, if it emits black smoke or burns, it means that chemical reagents are added, and it is not real diatom mud.

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?
