What slate is made of: composition and harmfulness
Back in Soviet times, slate was used for roofing asbestos-cement type. Until that day, this type of roofing material was considered one of the most budgetary and easy-to-install options. From the moment such products appeared, almost no one thought about what slate is made of, whether it is dangerous to human health and if it is dangerous, then what exactly.
During the installation work, only the reliability of the sheet fastening was taken into account so that the material did not fall from the roof during the operation process, no leaks and cracks appeared. Later, most people began to think about what exactly the products were made of, and scientists began to be interested in questions regarding the safety of all components for health.
To understand exactly what kind of harm roofing materials can bring, you should first familiarize yourself with the production process and the constituent components.
Most consumers are interested in the question not only about what kind of harm slate can cause to human health and what it is made of, but also how exactly do it. It is important to take into account the following fact that the formation process of the solution takes place in the production process, and it necessarily includes asbestos, Portland cement and water.
There are many factors that can have a direct impact on the final quality of the finished product:
- Storage process.
- Grinding thickness.
- Technical parameters.
- Mineral-chemical asbestos composition.
For a significant increase in the technical parameters of finished products, the roofing material is painted using silicate or phosphate-binding coloring compositions for such purposes. As practice has shown, in such compositions there are special pigments, which may contain special pigments that can protect the layer on the surface of the finished product. Due to the presence of such a layer, the finished product becomes resistant to the influence of low temperature conditions.
Moreover, this approach makes it possible to significantly increase the service life.
The popularity of this material for roofing dates back to Soviet times. It is required to take into account the fact that previously finished products were produced only in gray shades, and at the moment the assortment range is being made much more diverse. In the case of raw materials production, everything is poured into special containers, in which the products will achieve the required degree of reliability, and even become stronger. In the market for services and goods for sale, it is possible to find many different types.
Seven-wave - in this case, the name will speak for itself (the asbestos-cement sheet has 7 waves).
Among the technical characteristics, the following points can be noted:
When carrying out installation work, it is recommended to use special nails or glue for fixing on the roof.
The step of one wave will be about 0.15 meters, and while their height can reach up to 4 cm.As practice has shown, the extreme wave will be smaller in size than the rest, but you should pay attention to the fact that this does not violate the norms and requirements according to GOST.
Eight-wave - at the moment when specialists begin to manufacture roofing materials, they adhere to the requirements established by GOST 30340-95. Finished products have the following dimensions:
Each wave has a step of 0.15 meters, and a height of 4 cm. Soft - this type of material began to be produced relatively recently, which is why this slate is a new material on the service market and goods.
A feature of such products is complete safety and environmental friendliness not only for people, but also for the environment. This type of roofing material is made from natural mineral components. What is slate made of (composition)? The main component that is part of the finished product is mineral fibers, which are impregnated in advance with specialized formulations based on bitumen. The main advantage is a long service life and low weight.
Metallic - at the moment when this type of material is made, sheets of galvanized steel are used, which will result in a wavy metal slate.
Due to the introduction of innovations, the finished product needs to be driven under pressure, which makes the material wavy. This type of coating is actively used in order to equip the roof in industrial buildings. Flat - as practice has shown, the composition of this material for the roof is not much different from other types. The main components are cement mix and asbestos. This type of material is actively used for the construction of high-rise buildings, country houses and outbuildings.
As practice has shown, almost all consumers with the word "slate" represent a mixture of asbestos-cement type, which the manufacturer gave a wavy shape. It is important to take into account the fact that on sale there is an opportunity to find a huge number of varieties of material.
Please note that if we consider the composition of flat slate, as well as the harm from it, it should be noted that it is still not fully known which specific components are used in the production process of finished products.
If we consider the composition and harmfulness of slate, then it should be noted that previously the natural roofing material was made of slate.Such products, as a rule, were used for roofing, as a result, its slate could protect the room from rain, snow and strong wind gusts.
Slate slate has long been considered convenient to use and resistant to wear.
Gradually, the slate was replaced by another type, more accessible - asbestos-cement slate, which in a short time span conquered not only the Russian, but also the European market. As it became known, the slate was invented and patented by the Australian engineer L. Gatchek. Due to its development in 1902, a company was founded that made slate and sold it on a production scale.
Gradually, the industry began to conquer the markets of Italy, France, and also the Czech Republic. In 1908, roofing material began to be made on Russian territory.
Primary production of the material in Russia was concentrated in such a settlement as Fokino, which was located near the Bryansk region. Because of this, on the territory of the Russian Federation there are the largest reserves of minerals, from which the material for the roof was made, and the slate began to gain momentum.
So, before the beginning of the Great Patriotic War, 6 factories were made, which produced slate, and they were located in the following cities:
During the hostilities, certain enterprises decided to move to the east. Most of the factories were destroyed in wartime, they were not subject to reconstruction in the future. Slate gradually became the main material for the manufacture of roofing. It was used not just for roofs, but also as a facing material for building fences. As a result, competition gradually increased, and the cost of finished products began to fall significantly, and demand increased, as a result of which slate became popular in a large number of construction areas.
Slate was actively used as a roofing material. In this case, when buildings had to be demolished, the asbestos-cement slate was carefully removed and reused in the future.
You know what slate is made of (composition and harmfulness). During the restructuring, the number of manufactured products fell sharply. After the collapse of the USSR, the factories were reduced, which is why out of 58 of them, only 28 continued to work, which significantly reduced the assortment of finished products.
If we consider the full name of the finished product in accordance with GOST, then it will sound like this - asbestos-cement flat or corrugated sheets. In the production of slate raw materials such as ox, asbestos fibers and cement were used. It is required to take into account the fact that asbestos fibers are a constituent component of which slate is made. Most experts are inclined to assume that asbestos, from which slate is made, has an adverse effect on human health.It is extremely important that at the very beginning such sheets were called "eternite", which in translation means "eternal".
Is slate really harmful or not - this is the moment that worries most consumers. In this case, opinions differ greatly: some argue that the material is harmful to the human body, while others are inclined to assume that this myth was invented by manufacturers of more expensive roofing materials. When mixing the slate solution, add asbestos fibers. This component is considered to be very harmful, as a result of which a person is able to become very sick if this element enters the human body.
But here one should take into account the following fact that asbestos fibers are divided into 2 groups:
In this case, the first option is considered harmful, but it is used only in European countries in the absence of the first component. It is for this reason that we can conclude that slate, which is made from asbestos chrysolite fibers, which are less hazardous to human health.
Slate can be made from chrysolite asbestos fibers, water and cement mixture. This type of roofing material does not harm the environment and human health, as a result of which the slate can be used without fear.
