With or without contamination of diatom mud coatings, selection and construction is the key

News: Diatom mud is an all-natural
coating
products, mainly because it is a seaweed living in the ocean, the main component is protein, soft texture, porous. In recent years, it has been widely used in the construction industry. But why is there diatom mud wall formaldehyde, VOC, pollution over-standard news? Mainly from its construction and construction materials, reporters through visits to diatom mud professionals, for the vast number of consumers to share how to choose diatom mud and construction methods.
1, before the purchase of the best first goods than three, more understanding of the relevant diatom mud product information. For different brands, packaging products, from the quality, price, service, corporate reputation and other aspects of comprehensive consideration.
2, diatom mud as a new powder decorative coating, many brands, when buying should pay attention to the following points:
A, functional:
a, absorbent diatom mud itself has numerous tiny holes, so it is decided that it has a very strong adsorption. But water absorption is not the way to detect the quality of diatom mud, diatom mud on the water is a certain repulsion, so can only be identified in the form of water spray fog.
b, with a sealed glass bottle to identify the diatom mud adsorption function, take two sealed glass bottles, in one bottle into half a bottle of diatom mud dry powder, the other bottle is an empty bottle, and then smoke a large mouthful of smoke blown into two bottles, and then covered with a seal. Ten minutes later, open the lid and smell the diatom mud in both bottles, which have little smoke, while the empty bottle smells of heavy smoke.
B, decorative texture thick, texture pattern natural simple
C, durability 30 years do not fade, powder, slag, peeling and other
D, environmental protection, health and environmental protection, zero formaldehyde zero pollution zero VOC, reduce light pollution
1, to ensure that the substation is flat, dense, clean, moisture content is less than 10%, PH value is less than 10, yin and yang angle and line horizontal vertical;
2, in the professional and technical personnel in accordance with the on-site climatic conditions to develop diatom mud formula, according to the method provided in the raw material proportionally added water, and on-site stirring for a certain period of time, so that the mixture fully dissolved, complete reaction;
3, carefully cover the part without spraying, check the base surface conditions to meet the required requirements before construction, pay attention to ensure timely adjustment of construction speed, to ensure that the outer wall wet film thickness of 3mm, dry film 2mm, inner wall wet film thickness of 1.2mm, dry film 0.9mm;
4, the coating rate is about 0.8-1.0m3/kg.
