MIS ERINEVUSED ON LOODUSKIVIDEL JA TEHISKIVIDEL? maastikukivi

Looduslik kivi on vanim ehitusmaterjal inimarhitektuuri ajaloos, mängib olulist rolli igapäevaelus. Looduslikust kivist tooted kasutatakse laialdaselt lennujaamades, kiirraudteejaamades, kõrgekvaliteedilistes hotellides ja muudes suurtes avalikes hoonetes, ärihoonetes, elamutes, hauakivides, monumentides jne. Nüüd saavad kodukaunistamise protsessis üha enam tähelepanu kivitooted, kuid viimastel aastatel tõuseb kivitoorme hind iga aastaga, nii terminali kliendid kui ka tootjad kurdavad kulude kasvu üle.

Ebakorrapärased kivid

Tänapäeval, majanduse arenedes, on keskkonnasõbralikud hooned, energiasäästlikud ehitusmaterjalid laialdaselt aktsepteeritud enamiku maailma klientide seas. Kas tehiskivid avaldavad tulevikus looduskivitööstusele mõju? Või on see ainult looduslike kivide lisand? Kas tehiskivi asendab loodusliku kivi? See artikkel aitab teil vastuse leida.

Looduskivist ja tehiskivist õige arusaam

Mis on looduslik kivi?

Looduskivi viitab sette- või moondekarbonaatkivimitele, nagu marmor, dolomiit, lubjakivi, liivakivi, kiltkivi ja kiltkivi. Kaasaegne looduslik kivi kaevandatakse looduslikust kivist ja seejärel pärast mitmeid töötlemist, viidates kodukaunistamisel kasutatavale materjalile, on üldehituslik dekoratiivne looduslik kivi peamiselt graniidist ja marmorist kahte tüüpi.

Graniit on tardkivim, mida nimetatakse ka happekristalliliseks plutoonkivimiks. See on päevakivi, kvartsi ja vilgukivi koostiselt kõige laiemalt levinud tardkivim, kivikõva tihe. Graniit koosneb peamiselt ränidioksiidist, ca 65%-75% nn tardkivimist moodustab kivimi laavakristalliseerumise maa-alune magma ehk vulkaanipurse.

Marmor on moondekivim, mis on tekkinud kõrge temperatuuri ja rõhu mõjul Kesktasandiku maakoores. Maakoore sisejõud põhjustab algsete kivimite kvalitatiivseid muutusi, st muutub algsete kivimite struktuur, struktuur ja mineraalne koostis. Metamorfismi teel tekkinud uusi kivimeid nimetatakse moondekivimiteks.

Mis on tehiskivi?

Tehiskivi on valmistatud küllastumata polüestervaigust sideainena, looduslikust marmorist või kaltsiidist, dolomiidist, räniliivast, klaasipulbrist ja muudest anorgaanilistest materjalidest, samuti sobivas koguses leegiaeglustit, värvainet jne, see on valmistatud koostisainete segamisel. , keraamika valamine, vibratsiooni kokkusurumine, ekstrusioon ja muud meetodid.

Kuigi tehiskivi on sünteetiline, on sellel tavalise kivi omadused. Näiteks on sellel leegiaeglustav, kulumiskindel, löögikindel ja see ei ole radioaktiivne. See on ka üks looduskivi ja tehiskivi erinevusi. Nagu eespool mainitud, on tehiskivist uut tüüpi kodukaunistamismaterjal. Sellegipoolest on selle müük silmapaistev, kuna sellel on loodusliku kivi värv ja tekstuur. Sellegipoolest on hind tavalisest looduskivist madalam, see on üks looduskivi ja tehiskivi erinevusi.

Looduskivi ja tehiskivi eelised ja puudused

Loodusliku kivi eelised:

Looduslikul kivil on kõrge tugevus, hea kulumiskindlus, korrosioonikindlus, madal veeimavus ja ilus tekstuur. Marmorit kasutatakse peamiselt sisekujunduses ja graniiti kasutatakse peamiselt välistingimustes, marmorit suurepärase kõrge temperatuurikindluse tõttu, sobib köögi tööpinnale.

Loodusliku kivi puudused:

Looduskivi on pooridega, kergesti kogunev rasv. Üldiselt vajab see suure tiheduse tõttu tugevat kapi tuge;
Kuigi tekstuur on kõva, kuid elastsus on ebapiisav.
Pealegi on seda ka raske parandada, kui seal on nähtamatud looduslikud praod.
See puruneb kergesti, kui temperatuur muutub kiiresti.

Tehiskivi eelised:

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

Välimus

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.
