天然石与人造石有什么区别？景观石

天然石材是人类建筑史上最早的建筑材料，在日常生活中发挥着重要作用。天然石材产品广泛应用于机场、高铁、高档酒店等大型公共建筑、商业写字楼、住宅、墓碑、纪念碑等。现在在家庭装修过程中，石材产品越来越受到重视，但近年来，石材原材料的价格每年都在上涨，无论是终端客户还是厂家都在抱怨成本的上涨。

不规则的石头

如今，随着经济的发展，绿色建筑、节能建材被世界大多数客户广泛接受。人造石未来是否会对天然石行业产生冲击？还是只是天然石的补充？人造石会取代天然石吗？本文将帮您找到答案。

正确认识天然石与人造石

什么是天然石材？

天然石材是指大理石、白云石、石灰石等沉积或变质碳酸盐岩，砂岩、页岩和板岩。现代天然石材是从天然岩石中开采出来，然后经过一系列加工而成的，至于家居装饰所用的材料，一般建筑装饰用的天然石材主要有花岗岩和大理石两种。

花岗岩是一种火成岩，又叫酸性结晶深成岩。它是分布最广的火成岩，由长石、石英和云母组成，岩石坚硬致密。花岗岩的主要成分是二氧化硅，约占65%-75%。所谓火成岩就是地下岩浆或火山喷发的熔岩结晶而成的岩石。

大理石是中原地壳经高温高压作用形成的变质岩，地壳内力作用使原有岩石发生质的变化，即原有岩石的构造、结构、矿物成分等发生改变，经变质作用形成的新岩石称为变质岩。

什么是人造石？

人造石是以不饱和聚酯树脂为粘结剂，以天然大理石或方解石、白云石、硅砂、玻璃粉等无机材料以及适量的阻燃剂、颜色等，经配料混合、陶铸、振动加压、挤压等方法制成的。

人造石虽然是人工合成的，但是它具备普通石材的特性，比如具有阻燃、耐磨、耐冲击、无放射性等特点，这也是天然石与人造石的区别之一。如上文所说，人造石是一种新型的家装材料，但是由于它具备天然石的色泽和质感，所以销量十分突出，价格也比普通天然石要低，这也是天然石与人造石的区别之一。

天然石与人造石的优缺点

天然石材的优点：

天然石材强度高、耐磨性好、耐腐蚀、吸水率低、纹理美观。大理石主要用于室内装饰，花岗岩主要用于室外装饰，大理石因耐高温性能优良，适合做厨房台面。

天然石材的缺点：

天然石材有孔隙，容易积聚油脂，一般密度较大，需要较强的柜体支撑；
虽然质感较硬，但是弹性不足。
另外，如果存在一些看不见的天然裂缝，修复起来也很困难。
当温度急剧变化时，它很容易破裂。

人造石的优点：

Artificial stone has the advantages of bright color, high finish, uniform color, resistance to pressure and abrasion, good toughness, compact structure, strong and durable, light specific gravity, non-absorbent, erosion and weathering resistance, small color difference, non-fading, low radioactivity and so on. The stone material is easy to process into the mesa’s geometry, mesa, and so on.

Disadvantages of the Artificial Stone:

The general naturalness of artificial stone is obviously insufficient, its texture is relatively false. Moreover, because the artificial stone manufacture craft difference is huge, the characteristic is not completely consistent. Due to the internal part of the resin material, if in direct contact with overheating containers, easy to heat deformation.

3 Misunderstandings About Natural Stone and Artificial Stone

Does The Natural Stone Have Radiation, and Will It Endanger The Human Body Being?

Natural Stone has radiation, carcinogenic rumors one after another, many consumers worry about the natural stone in the presence of radiation. Does natural stone really contain excessive radioactive material to endanger human health?
There is a mandatory standard for quantifying the radiation of building materials, which is classified into four categories: A, B, C and D, of which Class A is the building materials that can be safely used in any situation. All marble on the market is a class, only a few granite is a class B, class B must be installed in the ventilation used, class C and Class D has not yet been found in the market.

Is Natural Stone A Better Choice Than Artificial Stone?

After millions of years of qualitative changes, the natural stone formed a different color and texture. Natural stone has a very high decorative texture and decorative grade. It has high ornamental value and always gives people beautiful feelings.
Artificial stone can be divided into organic artificial stone and inorganic artificial stone, the two differences lie in the use of different adhesives. In fact, after years of technological improvements, the entire industry now has the technology to ensure that both types of stone are healthy for the human body.
Natural Stone and artificial stone are two different fields, while they have a good complementarity, consumers could make a choic according to their actual needs, such as application areas, price range, environmental requirements to choose.

The Higher The Price, The Better The Quality?

No matter natural stone or artificial stone, the price level relies on many factors: stone material supply, mining difficulty, processing cost, transportation distance, labor cost, marketing cost, etc., so it doesn’t mean the higher the price the better the quality. Usually, consumers make their choices based on their actual needs to choose some medium-priced products.

Top 5 Driving Factors That Distinguish Between Natural And Artificial Stone

外貌

Natural Stone is a natural material, is transparent or translucent particles, very beautiful. So the natural stone feels brighter. Artificial stones are made from common natural stone powders or opaque acrylic materials, but they are also made by adding glue to the stone and pressing it. Its surface brightness is not as beautiful as that of quartz and can be said to be close to dull.

Handfeel

The other easiest way to tell a natural stone from an artificial stone is to touch it with your hand and then distinguish the two different stones by the feel of your hand. Natural stone material, the feeling that our hand touches above gives a person is the cold feeling. It’s like touching a natural stone. Artificial stones are different. Because the artificial stone material used inside the plastic material, so we do not touch the feeling of ice-cold, give the most obvious feeling is warm and delicate. This feeling is basically the same as when we touch other plastic materials.

Hardness

Hardness is an important mark to distinguish natural stones and artificial stones. According to shore hardness, granite is defined as not less than 70(HSD ≥70) and marble is defined as less than 70(HSD < 70). Natural Stone is natural and relatively hard, so it is still not as flexible as artificial stone, while artificial stone is relatively soft so that it can do radian, splices are usually invisible at the seams.

PH Tolerance

There is a very simple method is to use hydrochloric acid test, a few drops of dilute hydrochloric acid on the stone surface, granite no obvious reaction, natural marble surface will appear rich foam, artificial marble foam weak, there is no bubble at all.

Permeability

The permeability of natural stone is stronger than that of artificial stone. Drop colored liquid on the surface of natural stone, the color will penetrate into the stone, not easy to remove the traces left: and artificial stone permeability is worse, color penetration is slow if cleaned in time will not leave traces.

Bottom of Line

Today, natural stone mining is rampant, and it becomes scarce. Compared with natural stone, the characteristics of artificial stone also make it become the most important type of decorative material in landscape decoration today. They have many types and different uses, and the use method is very different according to their properties. No matter what kind of material, each has its own advantages and disadvantages. We should choose the material that suits us best according to our own needs and prices. Artificial stone has existed a long time in society and occupies a place in the stone market, it’s clearly impossible to replace the natural stone.
