Detect the surface gloss of marble: The surface gloss of marble will greatly affect the decorative effect. Generally speaking, the polished surface of high-quality marble plates should have mirror-like luster, which can clearly reflect the scene. However, due to the different chemical composition of marbles of different qualities, even products of the same grade will have a great difference in gloss. Of course, the surface glossiness of the sheet material between different grades of the same marble material will also have a certain difference. In addition, the strength and water absorption of the marble sheet are also important indicators for evaluating the quality of the marble.

Four characteristics of marble:  1. No deformation After long-term natural aging, marble has a uniform structure, a very small linear expansion coefficient, and the internal stress completely disappears without deformation. 2. High hardness Marble has good rigidity, high hardness, strong wear resistance, and low temperature deformation. 3. Long service life No need to apply oil, not easy to stick to dust, easy and simple maintenance, and long service life. There will be no scratches, it is not blocked by constant temperature conditions, and the original physical properties of marble can be maintained at room temperature. 4. Not magnetized It can move smoothly during measurement, without a sense of stagnation, and is not affected by moisture. The plane is weighed well. The physical properties of marble: specific gravity 2970-3070kg/m3; marble compressive strength: 2500-2600kg/cm2; elasticity coefficient: 1.3-1.5¡Á106kg/cm2 water absorption.

According to the classification of marble, the naming principles are different. Some marbles are named after the place of origin and color, such as Dandong Green, Tieling Red, etc.; some marbles are named after patterns and colors, such as Snow White and Aiye Green; some marbles are named after patterns, such as autumn scenery and ocean waves; some marbles are Traditional names, such as white marble, crystal black jade, etc. Therefore, the phenomenon of similar names or different rocks with the same name often appears due to different origins. According to the basic color of the polished surface, the marble produced in my country can be roughly divided into seven series: white, yellow, green, gray, red, coffee, and black. Each series can be divided into several sub-categories according to the color and pattern characteristics of its polished surface, such as: white marble, rosin yellow, Dandong green, Hangzhou gray, etc. The pattern and crystal grain size of marble varies widely, including landscape type, cloud type, pattern type (thread, willow leaf, sculpture, ancient creature, etc.), snowflake type, etc. Modern buildings are colorful and constantly changing. Therefore, the decorative marble also requires multiple varieties and colors, which can be used in different parts ...

Marble is mainly used for processing into various shapes and plates, as the walls, floors, platforms, and columns of buildings, and is also commonly used as materials for monumental buildings such as monuments, towers, and statues. Marble can also be carved into practical works of art, such as arts and crafts, stationery, lamps, and utensils. The texture of marble is soft, beautiful and solemn, and elegant in style. It is an ideal material for decorating luxurious buildings and a traditional material for artistic sculpture. The main stone color of this marble is: multi-color, subjective attributes: marble pattern, high compressive strength and good physical and chemical properties, easy to process, with economic development, the scope of application continues to expand, dosage It is getting bigger and bigger, and it plays an important role in people's lives. In particular, large-scale mining, industrialized marble processing, and international trade have made decorative panels enter the building decoration industry in large quantities, not only for luxurious public buildings, but also for home decoration. It is also widely used to manufacture exquisite appliances, such as furniture, lamps, smoking sets and artistic sculptures. Some can also be used as alkali-resistant materials. Crushed stones and scraps produced in ...

Marble International is collectively referred to as marble. With its natural and simple texture, bright and bright color, it is widely used in building interior walls. Because the marble material is relatively loose, the texture is relatively soft and the water absorption rate is relatively high. There are many joint lines, so various pollution, warping and deformation, easy to lose light and other phenomena occur during processing, transportation, installation and use, which affect the decorative effect of marble. Therefore, the care of marble is also a required course in the nursing industry. . To compare and analyze the condition of marble finishes, the methods of care can be divided into: 1. Refurbishment and grinding treatment of marble. 2. Local drop processing of marble. 3. Protective treatment for cleaning marble. 4. Crystal polishing treatment. 5. Seamless filling processing, etc.

1. Marble is very fragile and is afraid of hard objects' impact and knocks. Therefore, you should usually prevent heavy objects such as iron objects from hitting the stone surface to avoid pits and affect the appearance. Granite and granite are easier to clean and maintain. Just use some cleaning agents to clean the surface of the marble in your spare time to keep it fresh for a long time. 2. Wipe the countertop regularly with a slightly damp cloth with a mild detergent, and then dry and polish it with a clean soft cloth. When the marble surface is stained, some mild corrosive agents such as lemon juice or vinegar should be used to clean the stain. Use soda powder and other materials that can damage the nature of the marble. You should also pay great attention to the use of lemon juice. The residence time should not exceed 1 minute. Repeat the operation if necessary, and then wash and dry it. For cosmetics, tea and tobacco stains, apply hydrogen peroxide, leave it for two hours, then wash and dry it. For oil stains, use ethanol (alcohol), acetone (wood spirit) or lighter oil to wipe, then wash and dry. ...

Was bei der Pflege von Marmor zu beachten ist: 1. Die Steinoberfläche sollte trocken und glatt sein. Nach der Aufarbeitung des Marmors, verwenden Sie Tierhaar-Pads oder Nano-Wolle-Pads so viel wie möglich, um die Bodentemperatur auf etwa 50 Grad zu trocknen, und dann tun Kristall Oberflächenbehandlung. 2. Bei der Pflege des Marmors müssen Sie saubere Stahlwolle und Scheuerschwämme verwenden. 3. Nehmen Sie es, wenn Sie es sehen. Wenn der Marmor ein Glaslicht ausstrahlt, sollte er sofort abgeschaltet werden. 4. Es ist am besten, neutrale Kristall Gesicht Agent und neutral renoviert Zellstoff bei der Pflege von Marmor zu verwenden. Marmor tägliche Wartung Kristall härtende Behandlung: Dies ist die beste Pflegemethode. Solange die Bedingungen erfüllt werden können, sollte diese Methode so oft wie möglich angewendet werden. Werkzeuge und Materialien: Marmorpflegemaschine (Scheuermaschine), roter Scheuerschwamm, Gießkanne, Staubschieber, Kristalloberflächenpflegemittel, Kristallhartpulver.

Neben den hohen Anforderungen an die Robustheit und den Umweltschutz der Platte wird bei Marmormöbeln auch die Radioaktivität des Marmors streng kontrolliert. Lange Zeit haben die Menschen fälschlicherweise geglaubt, dass Marmormöbel radioaktiv sind, und es ist unvermeidlich, dass es beim Kauf einige Bedenken gibt. In Wirklichkeit ist die Radioaktivität von Marmor sehr gering und schadet dem menschlichen Körper im Grunde nicht. Es ist eine Tatsache, dass Marmor Strahlung enthält. Es sollte gesagt werden, dass jeder Stein Strahlung hat. Es kommt auf die Größe der Strahlung an. Was die Radioaktivität von Marmor betrifft, so sind Experten des Forschungsinstituts für Normung der Staatlichen Verwaltung für Baumaterialien der Ansicht, dass natürliche Radioaktivität objektiv in der Natur vorkommt. Auch in natürlichen Marmorprodukten gibt es Radioaktivität, entscheidend ist, ob sie die nationale Norm überschreitet. Marmor wird aus Kalkstein in Sedimentgestein hergestellt, das durch äußere Faktoren wie Temperatur und Druck beeinflusst wurde. Da die Radioaktivität von Kalzit und Dolomit, aus denen er besteht, im Allgemeinen sehr gering ist, ist die Radioaktivität von metamorphem Marmor aus Kalkstein mit sehr geringer Radioaktivität ebenfalls sehr gering.

Dieses Granitmaterial enthält eine beträchtliche Menge Wasser, und das Vorhandensein dieses Wassers beschleunigt das Fortschreiten der Aktion und bewirkt, dass das Granitmaterial winzige Adern bildet und in den Gneis eindringt. Das Vorhandensein von Wasser erklärt die Bildung von feinkörnigen Gesteinsadern mit engem und geringem Widerstand, die sich weit ausdehnen; werden andere Methoden zur Erklärung ihrer Entstehung herangezogen, stößt man auf erhebliche Schwierigkeiten. Im Allgemeinen bildet der Granit ein riesiges Gesteinsfundament. In der Tat sind diese Gesteinsfundamente nur selten aus Granit, und die meisten bestehen aus Berggranit-Amphiboliten, steilen Gesteinen und Quarzdiorit. Es gibt jedoch auch Granite, von denen man annimmt, dass sie Felskappen, Felsbecken oder Felsdome bilden. Die Bestimmung des Granitvorkommens ist ein sehr wichtiges Thema. Die zur Beschreibung des Vorkommens verwendeten Begriffe haben aus der Sicht derjenigen, die sie verwenden, eine kausale Bedeutung.
