Chemical Bolt Inspection

Chemical bolts consist of a chemical hose, a screw, a washer and a nut. The screw, washer and nut are generally available in galvanized steel or stainless steel. Chemical hoses contain reactive resins, hardeners and quartz particles. Its working principle is through the special chemical adhesive, the screw will be cemented fixed in the alkaline substrate drilling holes, in order to realize the fixed parts of the wrong fixed composite parts.

Chemical Bolt Inspection

I. Preparation before testing

Before carrying out chemical bolt detection, the following preparations need to be made:

1, select the appropriate testing instruments and equipment to ensure their accuracy and reliability.

2、Prepare the standard sample for calibrating the instrument.

3、Prepare the samples and add the samples into the reagents for testing.

4、Ensure that the operator has professional knowledge and experience, and is familiar with the instrument operating procedures.

II. Instruments and equipment

Instruments and equipment commonly used in chemical bolt testing are:

1, atomic absorption spectrometer (AAS)

2, Inductively Coupled Plasma Emission Spectrometer (ICP)

3, chromatography - mass spectrometer (GC-MS)

When selecting instruments, factors such as testing purpose, testing requirements and actual conditions should be considered, and instruments provided by regular suppliers should be used.

III. Detection Methods

The main steps of chemical bolt detection include:

1, sample preparation: add the bolt sample to the reagent and mix the appropriate amount of diluent.

2, instrument calibration: use standard samples to calibrate the instrument to ensure that the instrument is accurate and reliable.

3、Testing samples: Use the calibrated instrument to test the samples.

4、Data processing: Process and analyze the sample test results to produce a report.

In the specific testing operation, the instrument should be operated in strict accordance with the operating instructions and operating specifications to ensure the accuracy and reliability of the test results.
