Natural stone refers to the general term that is mined from natural rock body and is processed into blocks or plate -shaped materials.Natural stone for building decoration mainly includes two major species of granite and marble.Natural stone has eternal, unique appearance and durability, but the installation cost is relatively high, and it is radioactive.
Natural stone mosaic
First, the characteristics of natural stone mosaic: 1. Mosaic has environmentally friendly shell mosaic, marble mosaic, and jade mosaic, etc., all made of pure natural raw materials, and no harmful substances are added during processing.In todays era of environmental protection and pursuit of nature, these natural materials are most satisfied with peoples environmental protection concepts.
Identification of natural stone
The quality of natural stone can be identified from the following aspects: 1. Observation: Observe the surface structure of natural stone with the naked eye.Generally speaking, the natural stone of a uniform fine material has a delicate texture and is a good product of natural stone; the appearance of the stone and the unspecified stone structure is poor, the mechanical performance is not uniform, and the quality is slightly poor.In addition, due to the impact of geological effects, natural stone often produces some fine cracks. Natural stone is most likely to break along these parts. It should be taken attention to remove.As for the lack of corners, it is even more important, and you should pay special attention when choosing.
Features of natural stone
1. All kinds of fire resistance are different, and some stones have chemically decomposed under high temperature.(1) Gypsum: Decomposed when greater than 107C.(2) Limestone and marble: Disappear when it is greater than 910c (3) Granny: At 600C, it is cracked due to uneven heating minerals.
The advantages and disadvantages of natural stone
I. Privey of Natural Stone: 1. Cheap price: Generally, 4 or 500 yuan can buy very good imported stone in the market, and this price can only be bought for mid -range artificial stones;Multi; 3. High hardness; 4. Dental density; 5. Darration of abrasion.These advantages of natural stone make it can be used in places where natural stone can be applied to outdoor traffic and high requirements for usage.
The difference between natural stone and artificial stone
1. Natural stone 1. It is also widely used in public buildings (hotels, restaurants, banks, hospitals, exhibitions, laboratories, etc.) and home decoration (kitchen table, face washing, kitchen -bathroom wall, dining table, coffee table, window sill, door, doorSet) Field.2. Advantages: ① The price is cheap: Generally 4, 500 yuan can buy very good imported stones in the market, and this price can only be bought in mid -range artificial stones; ②. The pattern is natural and more optional;③. The hardness is high; ④ is large density; ⑤ abrasion -resistant natural stone is used in places where the outdoor traffic flow is relatively large and requires high service life.
The radioactivity of natural stone
The National Building Materials Bureau, together with the Ministry of Health in 1993, formulated the "Radio and Classification Control Standards for Natural Stone Products".According to the radioactivity level of natural stone, natural stone products are divided into three categories: A, B, and C.1: Class A product.The scope of this type of product is not limited.2: Class B products.This type of stone products cannot be used for home decoration, but can be used for the inner and outer surface of all other buildings.3: Class C products.This type of product can only be used for the outer surface of all buildings.4: The radioactivity ratio is more than the stone products with a category Class C control value. It can only be used for other uses such as seaguies, pier and stele.
Types of natural stone
1. Marble marble is mainly composed of Fangli stone, limestone, snake pattern and white clouds.It is easy to weather and erosion, and it is easy to lose luster.There are two categories of marble used for decoration: natural marble and artificial marble.The TV, window sills, indoor grounds, etc. are suitable for marble.Marble is also widely used in high -end bathrooms, toiletting tables and tables of various furniture.When selecting marble decorative materials, you should fully consider the overall effects of the decoration, such as the beautiful and beautiful patterns on the marble light plate.When selecting marble decorative materials, whether the surface of the marble should be flat, there are defects in the corners, or whether there are cracks, scratches, or not, or whether the color tone is pure.
