Abstract
Description
Technical Field
[0001] The utility model relates to the field of air permeability comparison testing of latex materials, in particular to a latex material air permeability comparison testing device. Background Art
[0002] Latex generally refers to a colloidal emulsion formed by polymer particles dispersed in water, also known as latex. It is customary to call the aqueous dispersion of rubber particles latex, and the aqueous dispersion of resin particles emulsion. Natural latex refers to the glue liquid cut from rubber trees, which is milky white and requires the addition of ammonia or other stabilizers to prevent coagulation. The main raw material for human hygiene products and latex bedding is natural latex. The latex bedding made from it is natural and environmentally friendly, with excellent performance. It is a very good sleep product. Synthetic latex can generally be made into synthetic latex with a solid content of 20% to 30% through emulsion polymerization. If you want to achieve a higher content, you can use a method similar to natural latex to concentrate it. The main component is styrene butadiene rubber, which is widely used in tires, tapes, hoses, wires and cables, medical devices and other industries. It is also called universal rubber. In order to improve the air permeability of latex materials and make comparisons, an air permeability comparison test device is needed. The existing test devices mostly compare single results when comparing, so the air permeability test and comparison are not significant enough. Based on this, it is necessary to provide a test device that can improve the comparison significance and thus enhance practicality. In addition, the results of the existing test devices are simple, so the functionality of the test device is weak, which affects the versatility of the test device. Based on this, it is necessary to provide a test device that can significantly improve functionality. Utility Model Content

As the wind wheel 103 rotates, the wind passes through the receiving net 102 and the latex into the first test tube 107 and the second test tube 108 and is discharged from the air vent 110. The wind passes through the latex and blows up a number of foam particles in the leakage net shell 109, causing the foam particles to jump.
