Decorative stone has natural beautiful patterns and colors, more unique than other decorative products. It provides designers with a vast design space. At the same time, in the modern era of pursuing nature and advocating green environmental protection, more and more people in home decoration are using some natural stone. The following small series for everyone to introduce decorative stone cleaning and decorative stone types. Decorative stone cleaning 1, can not use non-neutral detergent Stone is afraid of the strong acidity of the liquid, in the cleaning of the stone can not be ignored for the cleaning agent composition. General cleaning agents contain acidity and alkalinity. Therefore, if you use a cleaner with unknown ingredients for a long time, the surface gloss of the stone will be lost. In addition, the non-neutral chemical residue on the stone is also the main cause of stone lesions in the future. 2, can not be arbitrarily waxed There are a wide variety of waxes on the market, including aqueous wax, stearic acid wax, oily wax, acrylic wax, and the like. These waxes basically contain acid-base substances. Not only will it block the capillary pores that the stone breathes, but it will also be stained with dirt to form wax scales, which will cause yellowing of the stone surface. When waxing is required in locations where pedestrians and goods are frequently circulated, professional maintenance companies must instruct waxing and maintenance methods. 3, can not long-term coverage of carpets, debris In order to keep the stone breathing smoothly, long-term coverage of carpets and sundries on the stone surface should be avoided, otherwise the moisture under the stone cannot be evaporated through the capillary pores of the stone. The stone will cause an annoying problem of stone lesions due to excessive moisture and increased water content. If you must lay carpets and pile up debris, please do not forget to move frequently. 4, to thoroughly clean and clean Whether hard granite (hardness HRs88-1114-7) or soft marble (hardness HRs46-773-5) is not resistant to the long-term turbulence of wind sand and soil particles. Therefore, it is necessary to use dust collectors or electrostatic mops to do a thorough job of dust removal and cleaning. The entrance to the commercial space is best able to place a dust mat to prevent the sand particles on the shoes from scratching the stone. It is advisable to change the wearer's sandals after entry to reduce the dust abrasion on the stone surface. 5, to regular protection To ensure the longevity of the stone, and to prevent the penetration of water and pollution sources, it must be regularly (depending on the type of stone and the quality of the protective agent, preferably 1 to 3 years for 1 or 2 treatments). 6, to immediately remove the pollution All stone materials have natural pores, and pollution sources (oil, tea, coffee, cola, soy sauce, ink, etc.) can easily penetrate the pores along the interior of the stone and form annoying stains. Therefore, we must choose a good quality stone special protective agent to prevent pollution sources of stone pollution. It should be noted that all protective agents are unlikely to block pollution for a long period of time. Therefore, if there is a contamination source on the stone, it must be removed immediately to prevent it from penetrating into the capillary pores. 7, to regularly maintain and maintain the gloss Light dust and cleanliness alone are not enough to keep the brilliant stone uninterrupted. Therefore, professional stone care personnel must be regularly invited to do the maintenance and maintenance of gloss regeneration. Such as: Recrystallize the marble surface with crystallization solution, or use the polishing powder to regenerate the marble or granite surface, or use breathable gloss protection agent, etc., can make your stone long-term new. 8, to keep the ventilation dry Stone is afraid of too much humidity in the environment. Water vapor will produce hydration, hydrolysis and carbonation of the stone, resulting in water spots, whitening, weathering, erosion, rust and other diseases, destroy the stone, so the installation of stone should always be kept dry and ventilated. 9, pay attention to the choice of protective agent varieties After the construction of the stone is protected, it must be able to maintain the permeability of the stone and waterproof, anti-fouling. Do not use the unknown protective agent to avoid not only failing to achieve protective effect, but increasing the difficulty of stone maintenance. Decorative Stone Type Granite 1. Formation: Granite is formed by underground magma spouting and intrusion cooling crystallization, as well as granitic metamorphic rocks. 2. Ingredients: The main component of granite is silica, its content is about 65% - 85%. 3. Chemical properties: The chemical properties of granite are weakly acidic. 4, structure; granite structure is usually a punctate structure, the particles are more coarse (referring to silica), the surface pattern is more regular distribution, high hardness. 5. Due to the special conditions and firm structural features of granite formation. Stone of decorative stone type 1. Formation: Slate is also a type of sedimentary rock and its formation is the same as that of sandstone. 2. Ingredients: The main component is silica. Its characteristics can be acid. Decorative stone type marble Marble materials are metamorphic rocks formed by the original rock in the earth's crust through the high temperature and high pressure in the earth's crust. The internal force of the earth's crust promotes the qualitative change of all kinds of original rocks, ie the structure, structure and mineral composition of the original rock are changed. The new rock formed through qualitative change is called metamorphic rock. Artificial stone of decorative stone type Artificial stone usually refers to artificial stone solid surface material, artificial stone quartz stone, artificial stone granite and so on. Different types of artificial stone, its composition is not the same. The composition is mainly resin, aluminum powder, pigments and curing agents. The application of polymer building materials, the manufacturing process is a chemical material reaction process, is a human science and technology with human progress and also continues to improve a practical scientific material artificial stone is mainly used in the building decoration industry It is a new type of environmentally friendly composite material. Compared to traditional building materials such as tiles, artificial stone is not only versatile, it is rich in color, and it has a wider range of applications. Artificial stone is non-toxic, radioactive, flame-retardant, non-stick oil, non-porous, antibacterial, mildew-proof, wear-resistant, impact-resistant, easy maintenance, seamless splicing, and varied shapes. Editor's summary: About decorative stone cleaning and decorative stone types are introduced here, I hope to be helpful to everyone.
