According to experts from the China Stone Industry Association, both granite and marble are microporous rigid materials with natural water absorption and may be contaminated during paving and use. The seemingly hard stone is actually very delicate and needs careful care during paving and use.
A professional protective agent must be used. In order to prevent damage to the high-grade stone, suitable protective agents must be selected for different stones and different paving positions: waterproof or oil-proof protective agents.
According to the China Stone Testing Center, there are a lot of consumer complaints due to improper protection and maintenance of stone by the cleaning company. According to experts, the scientific method of stone maintenance is to choose special cleaners and curing agents, and never use toilet cleaners instead.
The bathroom and kitchen stone need daily maintenance. The most important thing in daily use of marble floor is dust prevention, that is, to prevent dust from wearing on the floor. For example, local dirt can be wiped off with a wet hot towel, and then dried with a dry towel, or use Clean with professional cleaners. The most important thing in the bathroom is to prevent soap spots, shampoo, and other pollution. It can be maintained by 1-2 times a week with stone special maintenance wax.
The anti-oil treatment of kitchen countertops is the key, and fluorosilicone professional protective agents should be used for protection. Daily maintenance can be done in a similar way to bathroom countertops.
The radioactivity index of stone cannot be ignored. When it comes to radioactivity, people who are planning to buy stones for home decoration can’t help but feel a little worried.
Low-concentration radioactivity is fine. According to Wu Huishan, an expert who specializes in stone radioactivity, all-natural substances on the earth contains different amounts of natural radioactive elements. Naturally occurring low-concentration radioactive radiation not only does not harm human health but is also a component of the natural balance system. Experts suggest that when consumers choose stone products, marble, diabase and other relatively low radioactive stones that meet GB6566-2001 standards are suitable for bedrooms, bathrooms, and study rooms; when granite is used for floor decoration, living rooms, dining rooms, The kitchen is more suitable.
Buying natural stone depends on the “Radioactivity Test Report.” Ma Zhenzhu, director of the National Building Materials Testing Center and senior engineer, told reporters that when buying a stone, you must ask the dealer to provide a test report and show the “Natural Stone Products Radioactive Protection Classification Control Standard” Class A Or the value of category B. If it belongs to the “A category” value (that is, the radioactive radiation value is small), its scope of use is not restricted, that is, it can be used for family room decoration; if it belongs to the “B” value, it cannot be used for family room decoration. It can be used for the interior and exterior decoration of all other buildings; if the value belongs to “C” (that is, the radioactive radiation value is too high), it cannot be used for the interior decoration of various buildings, but can only be used for the exterior decoration of all buildings.
Good indoor ventilation is particularly important. Experts remind consumers that the most effective way to eliminate indoor radioactive radiation, radon gas, and various harmful gases is to strengthen indoor ventilation. Open the window for half an hour to 1 hour after getting up in the morning to make the night The accumulated dirty air with various pollution and fresh outdoor air fully circulate each other to ensure that the indoor air is fresh during the day. The windows are still open for half an hour to 1 hour before going to bed every night to ensure that the whole family sleeps comfortably and safely at night.
Natural stone: When choosing natural marble, it depends on whether the polished surface, that is, the surface is smooth, has a mirror luster, and can clearly reflect the scenery, whether the pattern lines are clear, whether there are breaks, and whether the impurities are obvious. The wear resistance and hardness mainly depend on the density. If the density is high, the wear resistance and hardness will be higher, and vice versa. If there are elderly people at home, it is best not to use it in a large area, because it is non-slip and prevents slipping and falling.
Artificial stone: Artificial stone has a lightweight, thin thickness, high strength, corrosion resistance, and patterns can be controlled manually. Generally, it can be divided into four categories:
Cement-type artificial stone: It is made of various cement as a binder, mixed with crushed marble, granite, industrial waste, etc., processed through some processes, also called “terrazzo”. This is relatively cheap, but has poor corrosion resistance and is prone to micro-cracks. It is only suitable for sheet metal.
Polyester artificial stone: It is made of unsaturated polyester as a binder, mixed with quartz sand, marble, calcite powder, etc., and cast into a shape. It is made through some processes. This kind of marble is what we usually call artificial marble. It is processed by imitating the surface texture of marble. It has mechanical characteristics similar to marble, and the pattern can be determined by the designer. It has good reproducibility and good performance. The processability can be made into different shapes, and the price is relatively higher.
Experts suggest that whether you are buying natural marble or artificial stone, you must obtain a certificate of radioactivity and harmful gas indicators from the merchant, or ask a professional inspection agency for testing.
