Marble is a metamorphic rock formed by the high temperature and high pressure of the original rocks in the earth's crust. The internal force of the earth's crust promotes the qualitative change of various types of rocks. The change of marble quality refers to the change in the structure, structure and mineral composition of the original rock. The new type of rock formed by the marble qualitative transformation is called metamorphic rock. Marble is mainly composed of calcite, limestone, serpentine and dolomite, and its main component is calcium carbonate, which accounts for more than 50%. Others include magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide. Marble is generally soft in nature, which is relative to granite. Of course, you don't need to bother about this, because this geological age is calculated in billions. In our lifetime, this marble qualitative change is a limited change. Marble floor tiles have attracted the attention of consumers with their gorgeous appearance and very practical features. The difference between marble and other architectural stones is that each marble floor tile has a different texture. The marble with clear and curved texture is smooth and delicate, bright and fresh, which is like a visual feast ...

大理石の物性は一般的に花崗岩に比べ柔らかい。室内装飾では、大理石はテレビのカウンタートップ、窓枠、屋内の床に適している。大理石は商品名であり、岩石学的定義ではない。大理石は、天然建築装飾石の主要なカテゴリーである。一般に、変成岩または非変成岩の炭酸塩岩のうち、装飾的機能を持ち、建築用石材や工芸品に加工できるものを指す。大理石は、大理石、石灰岩、ドロマイト、スカルンおよび炭酸塩岩石の異なる変質によって形成された大理石を指す。

天然大理石の用途が異なるため、その工業技術要求の焦点も異なる。天然大理石ブロック 建築材料工業標準（JC202-92）の天然大理石ブロックの主な要求事項は以下の通りである：大理石ブロックの形状は直角平行六面体であること。大理石の大きさは、長さが100cm以上、幅が50cm以上、高さが70cm以上であること。大理石の外観品質は、同一バッチの大理石ブロックの色相パターンが基本的に同じであること、大理石ブロックの角の欠落、縁の欠落、ひび割れなどの外観品質等級が表4.25.6の要件を満たしていることを必要とする。大理石の物理的性能要件（JCT202-2001）：かさ比重は2.6g/cm3 以上、吸水率は0.5% 以上、乾燥圧縮強度は50MPa 以上、曲げ強度は7.0MPa 以上。

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, ...

大理石の日常メンテナンス週に1～2回、大理石お手入れマシンとナノ・ウール・パッドを使い、きれいに洗った床面に少量のクリスタル・サーフェス・ケア剤またはクリスタル・ハード・パウダーをスプレーする。1平方メートルあたり1～2グラム。大理石ケアマシンで均一に塗り広げ、明るくなるまで磨く。最後に、ダストプッシャーを使って地面のホコリをきれいに押し出す。セクションごとに1～2平方メートルずつ吹き付ける。研磨パッドは清潔に保つこと。粉で汚れすぎると効果に影響が出るので、汚れが見つかった場合は、両面が汚れるまで反対側にも使用し、新しいものと交換する。作業場所にもよるが、大理石には十分な数のタワシを用意し、汚れたタワシは洗って乾かしてから使用する。滑らかな黒地の場合は、タワシをスチールワイヤースポンジパッドに変えてもよい。大理石を維持する効果は高まるが、地肌が滑らかでなかったり、ワイヤー・スポンジ・パッドが汚れていたりすると、地肌が黒くなるので注意が必要だ。

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 ...
