How to use the bond strength tester

by admin

the single-chip microcomputer digital display meter used in this instrument has a specially set section division display (i.e. two sections for measuring the strength of facing brick and concrete). Therefore, this instrument has the characteristics of high measurement accuracy, complete functions, novel structure and dual-use of one machine. It can check the strength of facing brick and measure the strength of concrete
bond strength: cohesion, also known as bond strength, is the mutual attraction between adjacent parts within the same material. This mutual attraction is the expression of molecular force between molecules of the same material. It is shown only when the molecules are very close (less than 10-6 cm). Cohesion enables substances to aggregate into liquids or solids. Especially in the liquid adhesion layer in contact with the solid, the liquid infiltrates the solid or does not infiltrate the solid due to the difference in the relative size of cohesion and adhesion. In rock mechanics and soil mechanics, τ= c+tan φ, Molar shear theory, C is cohesion, φ Is the internal friction angle, τ Is friction.

manufacturer’s instructions for high-precision bond strength tester

xl-5000a high-precision bond strength tester function: it can detect the bond strength of exterior wall facing brick, exterior wall external thermal insulation material, paint and coating on site. It is intelligent, with larger storage capacity and more convenient query Higher accuracy

applicable standards:

jgj110-97 standard for inspection of bonding strength of facing brick in construction engineering

jgj126-2000 code for construction and acceptance of exterior wall facing brick engineering

jgj144-2004 technical code for exterior wall external insulation engineering

jg158-2004 rubber powder polystyrene particle exterior wall external insulation system

jg149-2003 External thermal insulation system for exterior wall with expanded polystyrene board thin plastering

features:

it can not only measure the bonding strength of exterior wall finish, but also the bonding strength of exterior wall external thermal insulation materials, paints and coatings. Its biggest features:

(1) high precision: the minimum force value of 0.001kn can be measured; Intelligent backlight technology can be seen clearly even when detecting in the dark

(2) large capacity measurement data storage

(3) large screen LCD display and full Chinese menu, which can maintain the detection data \ store \ delete

(4) USB interface is adopted to replace the traditional RS232 interface, so the data transmission speed is faster and the storage is more convenient, Compatible with all computers.

(5) the first subdivision calibration technology makes the detection accuracy higher, the value more stable and the operation simpler

(6) high efficiency: compared with the traditional pressurization method, the pressurization speed of the detector can be increased by nearly 10 times, completely reducing the detection fatigue caused by improper pressurization structure

(7) it is powered by 6V battery, which can be used for a longer time and is suitable for long-time measurement needs.

the zxl-5000a instrument host is designed according to the industry standard code for construction and acceptance of exterior wall facing brick engineering, which can be loaded continuously and evenly, and fully meets the requirements of jgj110-97 inspection standard for bonding strength of building engineering facing brick. The specification of the standard block used is 95mm × 45mm × 8mm and 40mm × 40mm × 8mm, and the specification of standard test block of thermal insulation material is 100mm × 100mm × 8mm. When meeting the qualified requirements, the minimum tension is 0.64kn and the maximum tension is 2.56kn. According to the characteristics of low bonding strength and small bonding force of facing brick, the maximum tension is specially designed as 6.00kN to ensure the detection accuracy of the instrument

intelligent high-precision bond strength tester is the latest updated product. It is the preferred product of construction units, engineering quality inspection stations (centers), laboratories, scientific research institutes and supervision companies. It is very popular

precautions and maintenance

1 Digital pressure gauge is a precision instrument. In use, attention should be paid to shockproof, moisture-proof and forced pulling between connecting wire and plug

manufacturer’s instructions for high-precision bond strength tester

2 Each sensor is discrete. The sensor of this detector has been calibrated with the host, and cannot be exchanged with other sensors or host

3. When the digital pressure gauge displays Lo bat, it shall be charged in time, and the charger must use the special type of this instrument When charging, connect and charge with a large raised plug with a diameter of 3 mm

4. Always keep the tester and accessories clean. If necessary, add lubricating oil to the rotating parts The hydraulic system should be filled with clean N46 anti-wear hydraulic oil or engine oil with similar indicators

5. When drilling holes and grinding grooves in concrete, water must be added for cooling, otherwise the service life of drill bit and grinding wheel will be seriously affected

6. The tester has been calibrated before leaving the factory. During use, it can be calibrated once a year according to specific conditions

7. Users are not allowed to disassemble the instrument and any part of the tester without authorization, otherwise it will not be covered by the warranty

8. In order to ensure the correct use of the tester, please carefully read the terms in this manual and correctly select the test scheme with reference to relevant technical standards The product is guaranteed for one year. We are ready to provide you with technical consultation, instrument maintenance and calibration services, and sincerely hope you can put forward your opinions on the product

at the same time, it also provides test instruments, nondestructive testing, mechanical equipment, various test molds, various screening tools, concrete test instruments, cement test instruments, nondestructive testing instruments, highway geotechnical test instruments, asphalt test instruments, pressure machines, tension machines, cement The single chip microcomputer digital display meter used in this instrument has specially set section division display (i.e. two sections for measuring the strength of facing brick and concrete). Therefore, this instrument has high measurement accuracy, complete functions and novel structure, It can not only check the strength of facing brick, but also measure the strength of concrete

main technical parameters:

1 Maximum pullout force: 40kN

2 Piston stroke: 10mm

3 Inner diameter of chassis and point: 120mm

4 Digital display resolution: 0.01kN

5 Indication error: less than ± 2% F.S

6 Weight (main engine): 4.3kg

take out the host from the packing box, insert the power output plug of the power box into the socket on the whole machine, connect the power plug of the power network to the 220V power supply, the green indicator on the power supply should be on, and press the switch button

that thing is very simple. I don’t think you know the test method of bond strength ~ ~ ~ look at the standard
