Avoid home pollution, consider natural mineral coatings
Any modern home building materials have a history of development, as well as coatings. Our common types of coatings are usually synthesized by dozens or even hundreds of chemical components. Before World War II, most of the coatings used in the construction industry in Europe and the United States were obtained by firing natural stone. This traditional method of production can even be used. Back to the Roman era, many churches, palaces, etc., which have been left to this day, are basically painted with this paint. Chemical coatings emerged after World War II. Due to the destruction of a large number of buildings during World War II, the mineral coatings processed by natural stone could not meet the huge demand for post-war reconstruction in Europe, so chemical synthetic coatings came out and relied on the advantages of industrial mass production. It has been popular since then, and in addition to the use of mineral coatings in the restoration of monuments and the maintenance of royal palaces, the mineral coatings have gradually withdrawn from the stage, and the production process is even on the verge of loss. However, in recent years, with the rise of environmentalism and naturalism, mineral coatings have begun to revitalize in Europe and the United States. Many families have begun to abandon chemical coatings and re-use natural mineral coatings. Many commercial, government, and art institutions have demonstrated their environmental protection. The corporate culture of “green†has also begun to use mineral coatings. In 2011, UNESCO even listed the traditional mineral coatings production process in the Moron region of Spain as a list of best practices in the world's intangible cultural heritage, in recognition of the Spanish government's efforts to protect, restore and develop traditional handcrafts in the region. Outstanding work in coatings, and Morong Lime has become the only building material to date that has been included in the UN Intangible Cultural Heritage of the World. Mineral coating Mineral coatings are mainly obtained by calcining natural high-purity limestone, so the "gene" has natural and non-toxic properties. The main component of the finished mineral coating is alkali metal silicate, which can be applied to the air after being applied to the wall. The carbon dioxide reacts to form a silicic acid sol, and automatically infiltrates into the surface of the matrix such as the wall, so that the pigment, the filler and the matrix are silicified under the action of the curing agent, and are firmly integrated into one body, which is similar to the wall surface wearing a continuous and complete layer. The “stone†jacket has a durability that lasts for more than 15 years. From European engineering examples, there are even more than 20 years of experience. At the same time, because the coating film of mineral paint will not be water-permeable and can be "sweat" like human skin, in the chemical reaction process of solidification, it will naturally absorb the moisture of the wall substrate, so that the matrix remains dry, so the mineral coating ratio Ordinary chemical coatings are more stable, and are less prone to problems such as "foaming", "skinning", "cracking", and "shedding". However, the shortcomings of mineral coatings are also obvious. The main reason is the output and price. The mineral coatings in the Morong area of ​​Spain are still used as examples. The strict production protection makes the annual production itself constrained. The traditional craftsmanship makes it more expensive. At present, there are only a handful of domestic companies that represent mineral coatings in the Morong area. According to the author's understanding, the current coatings market is mixed, and many products claiming zero formaldehyde or zero VOC often refuse to provide authoritative test data to consumers. Take VOCs as an example, only the detection limit of less than 2g/L. The value can be said that the product is not detected by VOC. However, many well-known brands in the market, often VOC content of 10-20g / L, claim that VOC has not been detected, and even claimed to be a special paint for children's room. According to industry experts, for ordinary chemical coatings, to achieve the VOC undetected level, raw materials per ton higher than nearly 5,000 yuan, production time should nearly double, the merchants claim that the zero VOC products can be profitable from ordinary products. Imagine it. In the face of such market chaos, consumers are accidentally recruited, so it is recommended for home improvement groups with special environmental protection needs, such as newly-married couples who are eager to stay, pregnant or pregnant, physically sensitive children, elderly, asthma Patients may wish to consider the use of mineral coatings, and must provide authoritative testing data when purchasing, do not blindly listen to business advertising.
