How A Pull Off Adhesion Tester Works?

A pull-off tester measures coating adhesion to rigid substances like wood, concrete, and metal. It relies on a hydraulic system to pull away a test disk which is glued to the substrate material. The tester records the force applied when failure occurs. The pull off adhesion tester is widely used in quality assurance in construction to save time, as it is a reliable means to make sure that there is enough adhesion between the substrate and the coating. Here’s how the device works:

  • Manual mode - The tester is available in both automatic and manual modes. The manual hydraulic pump applies continuous and smooth pressure using a single stroke. Use the pull rate indicator to monitor and adjust the rate of pull manually. The internal memory can store the maximum pull-off pressure, test duration, rate of pull, and the dolly size for a maximum of 200 pulls. A manual pull off adhesion tester is compatible with PosiSoft software, so you can interpret or refer to the results on your computer.

  • Automatic mode – The automatic pull off adhesion tester has a rugged colour touch screen that can resist scratches and impact. The keypad will work even if you are wearing gloves. The automatic tester uses an electronically controlled hydraulic pump to automatically apply continuous and smooth pull-off pressure, reducing your need to exert effort and the risk of operators affecting the pulling process. You can adjust the pull rate, hold time, and pull limit, and take it with you on the field as it comes with a built-in rechargeable battery which should be good for more than 200 tests per charge. It can run on AC power even as the battery is recharging.
The internal memory can store the same details as the manual pull off adhesion tester , along with additional factors like user notes for thousands of pulls, the nature of the fracture, and pass/fail. The newest release testers come with Wi-Fi technology and Bluetooth.

Advantages of Universal Testing Machine

The main advantage of investing in a universal testing machine is that the device can be used to test the strength, durability, and suitability for most any material. A universal testing machine has the capability to pull, compress, bend, or stretch material to its breaking point. It is primarily used by laboratories that manufacture and or mould different types of plastics. A universal testing device features one or two vertical columns mounted on a base. A second horizontal plate contains attachments that are used to hold the sample and slides up and down during stress testing samples. Dual vertical column machines are preferred by most laboratories as they can handle larger samples in terms of size and weight. Determining tensile strength is the most common test performed in a universal testing machine. This is done by holding one end of a sample in place while the other is pulled away until two sides are torn apart. The same process is used for testing flexural str...

Uses for Universal Testing Machine

Universal testing machine or UTM is aptly named as it can perform various types of tensile and compression tests on different materials. There are also many different terms used to refer to a UTM that you will commonly hear in the industry, among the most popular of which are a tensile tester, bend tester, and compression tester. Some types of UTMs are stripped of some capabilities and/or are marketed to specific sectors, like texture analyzers for food, peel tester for adhesives, labels, and tapes, and top load compression tester for pipes and packaging. True UTMs can perform all of these and more. They are great multi-purpose instruments for any QC or R&D laboratory. The following are only a few common uses for UTMs: Tensile testing – One of the most common applications for UTM, a tensile test measure how strong a material is, how long it can stretch, and how stiff it is as the material is pulled apart until breaking point. Compression testing – Compr...

Importance of Ultrasonic Pulse Velocity Test in The Construction Industry

Image
In the construction industry, it is important to ensure that structures are built properly using the highest-quality materials and construction methods. Hence, certain tests must be conducted to ensure the quality of certain materials. The ultrasonic pulse velocity test is one of the most essential tests designed to determine the quality of natural rock and concrete. This testing method is preferred because it is non-destructive and it is conducted on site, saving builders a lot of time and money. In an ultrasonic pulse velocity test, the quality and strength of rock or concrete is determined by measuring the velocity of the ultrasonic pulse, which passes through the natural rock formation or concrete structure. The test is conducted using specialised equipment that generates a pulse of ultrasonic wave and measuring the time it takes for that pulse to go through the concrete. A high velocity indicates that the material is continuous and high-quality, and a slower velocity may ...
