Le proprietà fisiche del marmo sono generalmente più morbide rispetto a quelle del granito. Nella decorazione di interni, il marmo è adatto per i piani d'appoggio dei televisori, i davanzali delle finestre e i pavimenti interni. Marmo è un nome commerciale, non una definizione petrologica. Il marmo è una delle principali categorie di pietre naturali decorative per l'architettura. In generale, si riferisce alle rocce carbonatiche metamorfiche o non metamorfiche che hanno funzioni decorative e possono essere trasformate in pietre architettoniche o artigianali. Il marmo si riferisce a marmo, calcare, dolomia, skarn e marmo formato da diverse alterazioni di rocce carbonatiche.

Due to the different applications of natural marble, its industrial technical requirements have different focuses. Natural marblemarble blocks The main requirements of the building materials industry standard (JC202-92) for natural marblemarble blocks are as follows: Marble blocks must have the shape of a right-angled parallelepiped. The size of marble blocks requires a length greater than or equal to 100cm, a width greater than or equal to 50cm, and a height greater than or equal to 70cm. The appearance quality of marble requires that the hue patterns of the same batch of marble blocks should be basically the same; the appearance quality grades such as missing corners, missing edges, and cracks of marble blocks should meet the requirements of Table 4.25.6. The physical performance requirements of marble (JCT202-2001): bulk density is not less than 2.6g/cm3; water absorption is not more than 0.5%; dry compressive strength is not less than 50MPa; bending strength is not less than 7.0MPa.

The construction process of marble's grinding treatment and crystal polishing treatment: First, before refurbishing and polishing the marble, do waterproofing first. The purpose is to make the marble absorb as little water as possible, so as to reduce the water absorption rate of the marble. After 300#, do the waterproofing. At that time, the waterproof effect will be reduced or disappeared because of the grinding. If allowed, it is best to do waterproofing again after 800#. When encountering relatively loose marbles, such as white sand beige, sandstone, tropical rain forest, wood grain stone, etc., first use high-content sealing curing agent (such as super-hard inorganic coating, silicone resin sealant with a content of more than 40%) as pre-treatment. It makes the marble harden the material while filling the looseness.

Marble is easy to stain. When cleaning, you should use less water. Wipe it regularly with a slightly damp cloth with a mild detergent, and then dry and polish it with a clean soft cloth to restore the marble's luster. Or wipe it carefully with a liquid scrubbing agent. You can use lemon juice or vinegar to clean the stains, but the lemon should not stay on it for more than 2 minutes. Repeat the operation if necessary, then wash and dry. For minor scratches, special marble polishing powder and care agent can be used. For antique or valuable marble furniture, please ask professionals to deal with it. This maintenance method uses a stone recrystallization system, this system has two parts, one part refers to the machine tool part, the other part refers to some special chemical materials; chemical materials are also divided into two categories: one is marble and then The other type of crystallization system is the marble recrystallization system. The basic principle of marble is to combine some special chemical materials with the structure and organization of the stone surface layer and micro-rheological reaction by means of the heat generated by friction under the action of machinery, ...

Manutenzione quotidiana del marmo: Spruzzare una piccola quantità di agente per la cura delle superfici di cristallo o di polvere di cristallo duro sul pavimento pulito o lavato con la macchina per la cura del marmo e il pad di lana nano 1-2 volte a settimana. 1-2 grammi per metro quadro. Utilizzare la macchina per la cura del marmo per distribuire in modo uniforme, quindi lucidare fino a ottenere una superficie brillante. Infine, utilizzare lo spingi polvere per spingere la polvere a terra in modo pulito. La polvere deve essere spruzzata in sezioni, 1-2 metri quadrati per sezione. Il tampone di pulizia deve essere mantenuto pulito. Se è macchiato con troppa polvere, l'effetto sarà compromesso; se si scopre che è macchiato, deve essere usato sull'altro lato finché entrambi i lati non sono macchiati e sostituito con uno nuovo. A seconda dell'area di lavoro, il marmo deve essere dotato di un numero sufficiente di spugne, e quelle contaminate devono essere lavate e asciugate prima dell'uso. Su un fondo scuro e liscio, è possibile sostituire il tampone abrasivo con un tampone di spugna in filo d'acciaio. L'effetto di mantenimento del marmo è migliore, ma occorre tenere presente che se il fondo non è liscio o il tampone di spugna metallica è macchiato, il fondo diventa nero.

Granite is an intrusive rock in acidic magmatic rock. This is the most common type of rock in this category. Most of it is light flesh red, light gray, and off-white. Medium-coarse, fine-grained structure, block structure. There are also patchy structures, spherical structures, gneiss-like structures and so on. The main minerals of granite are quartz, potash feldspar and acid plagioclase, and the secondary minerals are biotite, hornblende, and sometimes a small amount of pyroxene. There are many types of accessory minerals, the common ones are magnetite, sphene, zircon, apatite, tourmaline, fluorite and so on. Quartz content is the largest among various magmatic rocks, and its content can range from 20-50%, and a few can reach 50-60%. The content of potash feldspar is generally more than that of plagioclase. The relationship between the two contents is often that potash feldspar accounts for two-thirds of the total feldspar, plagioclase occupies one-third, and potash feldspar is more in granite. It is light flesh red, but also gray and gray. Off-white potash feldspar and plagioclase are often difficult to distinguish on hand specimens. At this time, we must carefully observe the double crystal characteristics of these two feldspars, because plagioclase has double crystals. When ...

It is an indisputable fact that quartz is widely used in the garden. Quartz is beautiful, durable and cold-resistant. As time goes by, we subconsciously regard quartz as a symbol of eternal strength and hope. The quartz in the garden can not only be created into a variety of stone benches and chairs, but also can be used extensively on the steps. The winding path leads to a quiet place, and the path paved with quartz can create a poetic atmosphere for the small garden. The garden ground quartz can be made of natural quartz, sandstone, granite, concrete blocks, etc. In terms of design, each type of floor covering material has many changes, which can be matched and used at will according to people's imagination and taste. Paving has a great influence on the effect of the roof garden, but the paving is not an extension of independent building lines that integrate with the surrounding environment, and connect the house with the roof garden. This type of paving style is very flexible, and the roof garden also involves the paving of many garden roads. Close to nature, such as natural quartz or a piece of essential quartz. Gravel and pebbles ...

For people buying and using quartz, they hope that the life of the quartz can be extended in the application, and to achieve this requirement, quartz should pay more attention to the purchase and use of the quartz, so as to effectively obtain the results people need. Let's take a look at how to better extend the life of quartz? First, install quartz reasonably. If people need to install the quartz after purchasing, pay attention to the gaps that appear, because multiple quartz connections are usually used in work applications. As a result, too many gaps in the middle will seriously affect the description, because the long gap time will cause fractures. The situation happened. Therefore, in order to prolong the service life of the quartz, people should pay attention to this aspect when installing, and increase the optimization degree of the installation effect. Second, do a good job in the protection of quartz. Although the performance and other aspects are relatively good, it also has a good performance in resisting the impact brought by the outside world. If you want to let it explain the long-term use, not only should pay attention to the installation problem, people should pay ...

Because quartz itself is a very high-quality quartz, it can play an important role in the application by virtue of the high-quality performance of quartz, and it can also be used more obviously in decorative effects. So in life, many people invest quartz in important constructions such as road construction. Two issues that need to be paid attention to when buying quartz. First, whether the quality of quartz is good. Although most of the quartz quality is very good, but the area where the quartz is produced is different, and the materials and processes used are different. Such a variety of differences will cause the quality of the quartz to be very different. The different quality will have different performance in use, so when people buy the quartz, they need to pay attention to whether the quality is good enough. Second, whether the application of quartz is appropriate. Generally speaking, people buy quartz based on actual needs, and different structures of quartz will be applied to different fields. Only the proper structure can bring out all the advantages in the application. So when people buy quartz, they need to focus on whether quartz is suitable for use. People need to ...
