China's CNOOC building outdoor stone floor cleaning.
China Offshore Oil Building is located in the northwest corner of Beijing Chaoyang Gate East Second Ring Road, through on-site observation and analysis, we found that China's CNOOC building perimeter ground by litchi surface stone, flamed stone composition. After the construction of stone, cement surface residue more. Before installing the stone has not been protective treatment. In use, the vehicle travel frequently, and right-angle bend in the lane and heavy tire footprint, has been unable to discern the true nature of the stone from China stone supplier. Lubricant drip more temporary parking of vehicles, forming grease contamination. China's CNOOC building
spirit of scientific attitude, environmentally friendly philosophy, in order to avoid risks in construction and after construction, and also to be to achieve an ideal construction effect, require physical cleaning methods to clean the main, if necessary, use a small amount chemical cleaning. Non-slip characteristics combined with field stone and building requirements, the construction side tests carried out a variety of combinations to finalize the construction program as follows:
(l) using # 60 abrasive abrasive cleaning brushes. Require the use of sewage suction machine promptly sucked not let water into the stone from granite slab supplier.
(2) In addition to using a professional stone ointment were stone surface degreasing construction. Require oil spots clearance rate above 80%, if necessary, can be repeated washing.
(3) the use of a professional flower stone hammer remove the stone surface cement residue. Requirements can not be cleaned with abrasive brush, and use flowers hammer cleared. Are
(4) Check the stone surface there are other forms of pollution, and select the appropriate treatment of stone dedicated management agent. Requirements can use a variety cleaning agent, but to control the amount of cleaning agent, the cleaning agent to prevent contamination of the stone.
(5) using a 120 # abrasive grinding brush cleaning. Require the use of suction machine sewage timely net absorption, not residual water.
(6) Check the stone surface treatment of pollutants and, if necessary, you should use professional azul cielo marble cleaning agent.
(7) using # 180 polishing abrasive brush cleaning.
(8) using # 240 polishing abrasive brush cleaning.
(9) stone surface is dry. Requirements should be fully dry stone surface, ready for the next step to prepare the construction.
(10) brushing the stone surface and oil repellent. Required by the repellant construction requirements for construction, Protectant brushing twice.

6. Through the above process after construction, ground stone effect to the requirements of CNOOC building:
(l) clean surface stains stone, stone surface colors to the new stone colors;
(2) stone surface of the cement residue completely clean;
(3) stone surface clean oil stains.
(4) other pollutants clean. After two months after construction observation, no discoloration of the stone surface yellowing phenomenon.
