The maintenance of jade jewelry can be summarized as follows: the hardness of jade is very high, but it is easy to crack after collision. Sometimes, although the cracks cannot be seen with the naked eye, the molecular structure in the surface of jade has been damaged, with dark cracks, which greatly damages its perfection and economic value. Avoid dust as much as possible. If there is dust on daily jadeware, it should be cleaned with a soft brush; If dirt or oil stains are attached to the surface of the jade, they should be brushed with mild soapy water, and then washed with clean water. Do not use chemical degreasing agent or degreasing fluid. It is better to put it in the jewelry bag or jewelry box to avoid scratches or damage. If it is high-grade jade jewelry, do not place it on the counter to avoid dust and affect the transparency. high quality Sculpture processing Try to avoid contact with perfume, chemicals, soap and human sweat.

GRC components can be widely used in the internal partitions of offices, business and residential buildings, corridors and kitchens. The production process, installation and operation are simple and easy to master; The market prospect is broad and suitable for investors and entrepreneurs to explore and develop. However, the outstanding problems of ordinary magnesium partition board are: poor water resistance, easy moisture absorption and halogen return on the surface, and high water content. According to long-term research, development and production experience, Hainan EPS has fundamentally improved the physical and mechanical properties and water resistance of modified magnesium lightweight composite insulation board through reasonable production process and advanced and unique modification technology. This product has low cost, high strength Long service life, excellent heat and sound insulation effect, light weight per unit volume, etc., and no need to soak in water for curing after modification. It is mainly used for building wall insulation (such as reinforced concrete wall, ceramsite hollow block infilled wall, concrete hollow block wall, clay porous brick wall, etc.), building roof insulation system, steel plate roof insulation, ground insulation, warehouse insulation, pavement foundation, and can be widely used in many fields, such as refrigerator cars, square floors, airports, etc.
