To avoid home contamination, consider natural mineral coatings

China Coatings Network
: Any kind of modern home building materials have its history of development,
of
coatings. Our common types of coatings, usually composed of dozens or even hundreds of chemical compositions, and before World War II, the European and American construction industry used paint is mostly obtained by burning natural stone, this traditional production method, even dating back to the roman era, such as many churches, palaces and so on are basically painted with this coating surface.
Chemical coatings emerged after World War II, due to the destruction of a large number of buildings during World War II, natural stone processing of mineral coatings has been unable to meet the huge demand for post-war reconstruction in Europe, so the chemical synthetic coatings came out, and by virtue of the amount suitable for industrial mass production advantages to date, and mineral coatings in addition to the restoration of monuments, royal palace maintenance and other work continue to be used, gradually withdraw from the stage, the production process is even on the verge of loss. However, in recent years, with the rise of environmentalism and naturalism, mineral coatings began to revive in Europe and the United States, many families began to give up chemical coatings, re-use of natural mineral coatings; Many businesses, governments and art institutions have also begun to use mineral coatings to highlight their "green and green" corporate culture. In 2011, UNESCO even listed the traditional mineral coatings production process in the Moron region of Spain as a best practice list for the world's intangible cultural heritage, in recognition of the Spanish government's outstanding work in protecting, restoring and developing the region's traditional handcrafted coatings, and Morong lime became the only building material to date to be included in the United Nations World Intangible Cultural Heritage.
Mineral Coatings
Mineral coatings are mainly made by calcining natural high-purity limestone, so their "genes" have natural, non-toxic properties, the main components of the finished mineral coating is alkali metal silicate, painted to the wall can react with carbon dioxide in the air to form a silicate sol, and automatic seepage Into the wall and other substation surface, so that pigments, fillers and substates under the action of curing agent siliconization, firmly integrated into one, similar to the wall put on a continuous complete "stone" coat, its durability can be more than 15 years, from the European engineering examples, even more than 20 years of experience.
At the same time, because the coating film of mineral coatings will be like human skin neither seepage water nor can drain "sweat", in its solidified chemical reaction process, will naturally absorb the water of the wall substation, so that the substate remains dry, so mineral coatings than ordinary chemical coatings more stable, more difficult to appear "foaming", "skin", "cracks", "shedding" and other issues.
But the shortcomings of mineral coatings are also obvious, mainly production and price, still to the Spanish Morong region of mineral coatings, for example, strict protection of the origin of its annual output itself is constrained, traditional handicrafts production led to its price, the current domestic agent Morong region mineral coatings companies are few, among them The largest Jinan Messi New Materials Technology Co. , Ltd. in 2015 also only got the volume of 15 containers, its agent "Geffin" brand or added graphene "enhanced version" mineral coatings, the price from 2014 is all the way up, currently mainly for high-end villas, cultural relics protection units.
On the price, Jinan Moxie's person in charge said: "Gefen coating as the first brand of imported graphene mineral coatings, VOC, free formaldehyde, mercury lead heavy metal content tested by the authorities are "unexplored", but also added graphene, service life of more than 15 Year after year, to avoid secondary pollution brought about by subsequent renovations, these advantages calculate the comprehensive cost of consumer use is not really high, at present we are also gradually introducing some simple packaging products, and plans to build a production line in China during the year, after the import of limestone production in China, so that the overall price will be further reduced.
And according to the author understand that the current paint market fish and dragon mixed, many claims that zero formaldehyde or zero VOC products often refuse to provide consumers with authoritative testing data, to volatile organic VOC, for example, only in the content of less than 2g/L detection limit, can be said that the product is VOC not detected. But the market includes many well-known brands, often VOC content in 10-20g/L on the claim that VOC is not detected, or even claimed to be children's room-specific paint. According to industry experts, for ordinary chemical coatings, to achieve VOC unchened level, raw materials per ton is nearly five thousand yuan higher, production time is nearly double, merchants to ordinary products claim zero VOC products profits can be imagined. In the face of such market chaos, consumers carelessly on the trick, so it is recommended for the special environmental protection needs of the home improvement crowd, such as newlyweds anxious to stay, pregnant or pregnant, sensitive children, the elderly, asthma patients may wish to consider the use of mineral coatings, and when shopping must provide authoritative testing data, do not listen to business advertising.
