Tarpaulin, which is a common cloth for covering items, is usually used to cover goods, tents, temporary buildings, etc. The tarpaulin has the characteristics of waterproof, moisture-proof, abrasion-resistant, etc., which can effectively protect the items from the weather and environment. The material and process of the tarpaulin also vary depending on the use, such as waterproof tarpaulin, fireproof tarpaulin, UV resistant tarpaulin, etc.
Instrument recommendation: ETT-C universal material tensile testing machine.
1. Tear strength test: This is a test to measure the ability of the tarpaulin to resist tearing and cutting. In the test, one side of the tarpaulin is clamped in a clamp and a horizontal pull is applied by machine or manual until the tarp is torn. Test results are usually expressed as the difference in the length of the tarp before and after the test.
2. Tensile strength test: This is a test to measure the maximum tensile force that the tarpaulin can withstand. In the test, the tarpaulin is clamped in a clamp and a horizontal pull force is applied at a certain rate until the tarpaulin breaks. Test results are usually expressed as the difference in the length of the tarp before and after the test.

Universal material tensile testing machine is an experimental equipment used to test the mechanical properties of materials, which simulates various forces on materials in the actual working environment through tensile, compression, bending, etc., so as to obtain various mechanical property parameters of materials. This kind of equipment is widely used in various industries, such as construction, machinery, aerospace, etc., and is of great significance for the research and development, production and quality control of materials.
The working principle of the universal material tensile testing machine is mainly to measure the strain of the material under force by applying force. When a certain external force is applied to the material, the material will be deformed, and the universal material tensile testing machine can measure the magnitude of this deformation through sensors and measurement systems, so as to calculate the mechanical properties parameters such as elastic modulus, yield strength, and tensile strength of the material.
In a word, the universal material tensile testing machine is a very important experimental equipment, which is widely used in various industries. In order to ensure the accuracy and reliability of the test results, special care is required when operating and maintaining the equipment. Only through scientific and reasonable operation and maintenance can we ensure the long-term stable operation of the equipment, so as to provide important technical support for the R&D and production of various industries.
