The difference between a cloth clamping silicon tube and common silica gel tube
![]()
Cloth silicone tube is made of silica gel after high temperature heat curing, acid and alkali resistant, abrasion resistant, resistant to high temperature, corrosion resistance, is applied to chemical plants, refineries, port and industrial hot water and steam, automotive, medical, food and other industries, diving, silicone tube, especially the one with high quality silicon rubber as raw material, can withstand the pressure of multilayer high pressure resistant silicone tube.
Cloth silicone tube performance are as follows:
1, can be used for a long time at a temperature of 250 DEG C, the use of intermittent at 300 DEG c.;
2, hardness (shore A) / standard value of 60 + 5;
3, the blasting pressure / Mpa standard value is greater than or equal to 1.2, and the measured value is still in 6Mpa damage;
4, the high temperature performance: according to the standard requirements, placing 168h at 250 DEG C, tube inner and outer skin shall not have cracks, broken line phenomenon, hardness of not more than 70 (shore A), the blasting pressure is above 1.2Mpa. The internal and external surface of 300 DEG C X after 168h tube shall not have cracks and fracture phenomena. The test results reach the standard.
5, the low temperature performance: put 4H at the temperature of -55 DEG C, fast along the radial pressure to 50%, pipe inside and outside surface shall not have cracks and fracture phenomena. The test results show that the good performance at low temperature.
6, the interlayer adhesion: when in 50mm/min speed away, the adhesive strength between the inner and outer layer should be greater than 1.75KN/m. Because there is no test fixture, the test is not done;
7, ozone resistance: placing 70h in the depth of the ozone was 50 + 5pphm, 10 DEG C after, with double amplification without obvious cracks observation mirror surface. The sample testing commissioned northwest Rubber Research Institute, the conformity;
8, compression: after high temperature after the test hose, with the speed of 50mm/min along the radial compression to 50%, internal and external surface of the pipe shall be free of cracks. The test results of qualified.
