Coating knowledge: consumption misunderstanding: exposing four disadvantages of strong alkali diatom mud

Core tip: as we all know, diatom mud on the market has strong alkaline and weak alkaline properties, because pure diatom mud can't directly achieve the wall, many manufacturers on the market mix other materials in it, different manufacturers mix different things, most of which add calcium oxide The higher the content of Cao is, the less easy it is to remove the powder The worse the adsorption capacity is, the higher the pH value is, and the more alkaline it is The less the content of Cao is, the easier it is to remove the powder The better the adsorption capacity is, and the closer the pH value is to 7, the less alkaline it is The pH value of weak alkaline diatom mud is between 7-8, almost the same as that of human body and nature Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: as we all know, the diatom mud on the market has strong alkaline and weak alkaline properties, because pure diatom mud can not be directly achieved on the wall, many manufacturers on the market mix other materials in it, different manufacturers mix different things, most of which add calcium oxide The higher the content of Cao is, the less easy it is to remove the powder The worse the adsorption capacity is, the higher the pH value is, and the more alkaline it is The less the content of Cao is, the easier it is to remove the powder The better the adsorption capacity is, and the closer the pH value is to 7, the less alkaline it is The pH value of weak alkaline diatom mud is between 7-8, which is almost the same with human body and nature What is advocated is the original ecology, return to nature, and harmonious unity with human and nature Because of the high content of Cao, the strong alkaline diatom mud has some disadvantages: as a kind of wall material, the color of diatom mud is in the diatom mud powder In the process of applying diatom mud or in the process of drying diatom mud, the strong alkaline will have a great influence on the color, and the phenomenon of impure color is serious; If a kind of diatom mud product is not pure in color in the process of construction, it can definitely be a strong alkaline diatom mud [resulting in de dusting] the strong alkalinity of diatomite mud will cause corrosion to the binding substances in diatomite, so most of the strong alkalinity diatomite mud will show serious de dusting, and it will show good performance for a period of time after the completion of construction, and there will be continuous powder floating out of the diatomite wall after a week or a month, which is the reason People live indoors at least one-third of the time of the day The dust falling off will enter the respiratory tract and lungs with the breath, causing tracheitis, bronchitis and pneumoconiosis [quality decline] strong alkaline diatom mud contains calcium hydroxide, so there are various problems in storage and construction engineering Quicklime is mainly added to the strong alkaline diatom mud, which can react with glass active silica or active alumina at room temperature, and generate aqueous products to produce cementation [construction injury] some diatom mud construction workers will have hand pain, cracks and other symptoms a few days after diatom mud construction, which are actually caused by strong alkaline substances Because the strong alkaline diatom mud is very corrosive, it will burn the skin and not heal the wound easily Therefore, compared with strong alkaline diatom mud, weak alkaline diatom mud has obvious advantages Because the weak alkaline diatom mud is more close to the pure nature, without adding any chemical glue and lime as raw materials, the color of the diatom mud after the construction is more gentle, and the protection of eyes, especially the visual protection of children, is better The weakly alkaline diatomite mud product retains the most original breathing pores of diatomite, protects the functionality of diatomite from damage to the greatest extent, and enables the wall to realize real free breathing [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
