Physical properties bursting strength

The most cmcial physical properties of a milk filter are bursting strength, tear strength, tensile strength, filtration capacity, filtration efficiency, and air permeability and compatibility. The milk filters are available in glued, sewed, and sealed quality. 

Pressure Pipe Solid pressure pipe made with type I rigid PVC compounds have tightly controlled physical property requirements. Even though pipe manufacturers tend to be quite secretive about their formulations, these physical property requirements tend to yield formulations of amazing similarity. Due to burst strength requirements, it is difficult to make pipe cost effectively with resin with a lit-value below 65. Usually National Sanitation Foundation (NSF)-approved PVC resin with a lit-value of 65 or 66 predominates in these applications. 

Processing production of coal sample and physical mechanic parameters test are in strict accordance with the provisions of Measurement method of coal and rode physical and mechanical properties (GB/T 23561-2009), and Measurement method of coal seam impact tendency classification index (MT/T 866-2000). The experiment determined natural apparent density, compressive strength, consistent coefficient, elastic modulus, deformation modulus, wave velocity, rock burst energy index, elastic energy index, dynamic failure time, and other parameters. The determination results as shown in Table 1.
