Selection of diatom mud: four methods to distinguish weak alkali and strong alkali diatom mud

The core tip: the color of diatom mud is in the diatom mud powder In the process of diatom mud drying or in the process of applying diatom mud, strong alkalinity will have a great impact on the color, which shows that the phenomenon of flower color is serious Therefore, if a kind of diatom mud product has serious color in the process of construction, it can definitely be a strong alkaline diatom mud There are four methods to distinguish weak alkali from strong alkali diatom mud (the picture comes from the network) The calcium carbonate film formed on the surface of strong alkali diatom mud and weak alkali diatom mud has blocked the gap The test can prove that its ability to absorb air has been lost If you lose the Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings news: the color of diatom mud is in the diatom mud powder In the process of drying or applying diatom mud, strong alkalinity will have a great impact on the color, which shows that the phenomenon of flower color is serious Therefore, if a kind of diatom mud product has serious color in the process of construction, it can definitely be a strong alkaline diatom mud There are four methods to distinguish weak alkali from strong alkali diatom mud (the picture comes from the network) The calcium carbonate film formed on the surface of strong alkali diatom mud and weak alkali diatom mud has blocked the gap The test can prove that its ability to absorb air has been lost If you lose the ability to clean the air, it's not diatom mud Especially for children, the skin of children is soft and unavoidable, and they often touch the wall The texture of strong alkali diatom mud is hard, which will not only scratch children's skin, but also corrode children's skin with strong alkali, bringing unpredictable consequences The weak alkali diatom mud adopts inorganic mineral components, even the pigments are natural mineral pigments, the texture is soft and silky, there is no harm in contact with children's skin, not to scratch the skin, which is the best choice for children's room decoration In addition, the weak alkali diatom mud avoids the disadvantages of strong alkali diatom mud, such as easy to color and crack It can be reduced to mud for secondary use, which fully shows the natural properties of weak alkali diatom mud Identification method 1: pH value test method is very simple to determine the general formula direction of the manufacturer, whether it will block the hole, construction performance and other aspects; if pH is strongly alkaline, it will certainly affect the breathing performance and construction openness of diatom mud; At present, most of the manufacturers present a strong alkaline formula In fact, there are some problems in the formula idea The finished product shows strong hardness and poor water absorption A good diatom mud pH value should be between 7 and 8, that is, the natural weak alkaline property The pH value is equivalent to the natural spring water Method 2: rub the dry powder on the palm for a while If you feel your hands are burned or peeled, it means that it is a strong alkaline product Method 3: after the diatom mud is put on the wall, touch it with your hand, and you can't see that the powder can't be removed, and the powder is strong alkaline Method 4: after the diatom mud is dried and consolidated, dig a piece of it and put it in the water to see if it can be reduced to mud The composition of strong alkaline diatom mud contains gray calcium, which will form solidified calcium oxide after oxidation, and it can't be reduced! The other point is that under the bad weather, the construction will be carried out, and the strong alkaline diatom mud will be colored after it is made At present, there are many diatom mud products on the market, and the quality is uneven When consumers purchase, they must pay attention to distinguish whether diatom mud is strong alkaline or weak alkaline, and purchase cautiously Home of coatings focuses on the news and information of coatings, diatom mud, paint coatings, coating process, fire retardant coatings and coatings, paint coatings, coating process, decoration knowledge and decoration effect map of fire retardant coatings,
