Applicable to the determination and evaluation of surface treatment, sealing, adhesive layer, and thorough Layer and waterproof layer, etc. with asphalt layer, cement concrete layer, bridge deck.The strength of the interlayer bond between two different materials. Can also measure Bonding strength of the structural layer-bonding layer-structural layer.

Structural layer material strength pull-out tester

Model:LJLMG-1

I. Product Introduction

This instrument is mainly used to determine and evaluate the interlayer bond strength between surface treatments, sealing coats, tack coats, prime coats, and waterproofing layers and different materials such as asphalt layers, cement concrete layers, and bridge decks. It is also suitable for testing the bond performance of structural layer-tack layer-structural layer systems. The equipment meets the requirements of JTG 3450-2019 "Specifications for Field Testing of Highway Subgrade and Pavement" T0985-2019 Interlayer Bond Strength Test Method and complies with the relevant provisions of ASTM D7234 "Standard Test Method for Determination of Pull-out Adhesion of Coatings on Concrete Surfaces Using a Portable Pull-out Tester". It can be used for professional pull-out strength testing in engineering fields and laboratories.

II. Structural Features

1. The main unit consists of a loading system, a data acquisition system, a pull-out bracket, and pull-out accessories. The instrument can provide a uniform, vertically upward pull-out force with a tensile rate of 25 kPa/s ± 15 kPa/s.

2. The instrument is flexible and lightweight. The entire unit weighs approximately 40 kg, making it convenient for on-site testing. Indoor testing utilizes a ring test plate to fix the specimen.

3. Power supply is convenient. Outdoor testing requires only a 12V DC power supply. It can be directly connected to a car power source without needing additional power equipment. Indoor operation requires only a 220V power supply.

4. High accuracy. The instrument's test results have an accuracy range of 1N.

5. Digital display of pull-out force, peak value storage, and printing of test results.

6. 7-inch LCD touchscreen.
