With the popularity of diatom mud now there are a lot of false diatom mud, in fact, what they sell is putty powder or added photocatalyst and other chemical agents, these diatom mud all added chemical adhesives, not only does not have functionality, but also will release formaldehyde, benzene and other harmful substances, causing new pollution. In order to allow consumers to buy genuine products below we introduce some diatom mud identification methods.
1. Look at the specific gravity
There is a saying on the Internet (Lighter is better. If there is a large number of stone, the proportion is very large, the feeling is very heavy, indicating the low content of diatomite). In fact, the lighter the better, because the content of diatomite is strict, and diatomite is diatomite minerals after processing powder into the end, mainly depends on whether the pulverized diatomite construction to the wall has the function of adsorption and decomposition.
2. Look at the proportion of water added
When mixing to add water, the ratio close to 1:1 is the best; In practice, if the water added is less than 0.5, the content of diatomite may be less than 20%. But mainly depends on what the base is and the material of the base material.
3. Look at the color of the material
The real diatom mud wall material is added with inorganic pigment, so the color is natural, the color is soft and not sharp.
4. Water absorption
On the Internet, you can find such content: the faster the water absorption, the better the respiratory function of diatom mud, and respiratory function is the most basic function of diatom mud; If there is little water absorption, it indicates that the diatomite content is low or the diatomite micropores are blocked, and the diatomite mud has poor respiratory function. Spray a small amount of water, with the hand to touch, bad diatom mud, will drop powder or fade color, even can and mud. After the water dries, the bad diatom mud will leave traces or fade.
In fact, it is understood that the water absorption rate is not good or bad to reflect the diatom mud, because the water absorption is too strong, the wall is easy to cause damage to the wall. And the diatom mud wall surface is mainly breathable and impermeable, reflected in the adsorption, filtration function, there is a certain repulsion of water.
5. Scrub the surface of diatom mud with a wet rag
Good diatom mud, the surface can be wiped with a wet rag, pay attention to not scrub. And bad diatom mud, wipe, the surface will appear powder or fade.
6. Spray fire with a flamethrower on the diatom mud template
Good diatom mud can be fire retardant, heat insulation material, resistance to more than 1000 degrees Celsius high temperature. Fire refractory, no smoke, no odor.
The above is about the diatom mud selection and identification of the relevant introduction, if you want to know more about the diatom mud related information, please pay more attention to the Fuwojia home network, Fuwojia home network will provide you with more complete, more detailed, updated information.
