Cement bricks are in line with China's general guidelines for the development of building materials to protect farmland, save energy, adapt to local conditions, and draw local materials. This is in line with the State Council's opinion that “strictly restricting the destruction of bricks and bricks to actively promote wall reform†is in line with the State Administration of Taxation of the Ministry of Finance. The Caishuizi (1996) No. 20 document issued “Notice on Continued Implementation of VAT Preferential Policies for Certain Resources Comprehensive Utilization Productsâ€, which is a building material product subject to free value-added tax. Due to its high strength, durability, dimensional standard, complete shape and uniform color, it has a simple and natural appearance, and can be used as a clear wall or any exterior decoration. Therefore, it is a promising replacement product for replacing clay bricks.
Cement bricks are lighter in weight, higher in strength, and do not need to be fired. They are made of materials such as fly ash from power plants. They are more environmentally friendly and the country is already promoting it. The only shortcoming of this kind of block is that it is not as good as red brick in combination with plastering mortar, and it is easy to produce cracks on the wall surface, which affects the appearance. Water should be sprayed adequately during construction. For high-grade villas, consider a wall-mounted steel wire mesh to prevent cracks.
Zhejaing Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Meter, Mass Flowmeter, Mass Meter, Flow Meter, Flowmeter, ATEX, IECEx & CE approved. The product range covers different size from DN03 to DN150, and bigger sizes are being developed.
Sealand mass flow meter is designed and produced according to world`s latest Coriolis technology with exelent appearance, stability and accuracy to measure mass flow rate of a fluid traveling through a tube, widely applied to alternative energy, oil & gas, chemical, food & beverage, industrial energy, marine, power, pulp & paper, water & wastewater industries, etc.
Mass flow meter measures the mass based on Coriolis effort. The operating principle involves inducing a vibration of the tube through which the fluid passes. The vibration, though not completely circular, provides the rotating reference frame that gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift & amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid.
