HARKE-SPCAX3 Dynamic Contact Angle Measuring Instrument

Brief description: The dynamic contact angle measuring instrument is used to measure the wettability of liquids to solids. By measuring the contact angle of liquids to solids, calculating and measuring the free energy of liquids, i.e. the adhesion and tension of liquids to solids, this instrument can be widely used in fields such as petroleum, chemical, pharmaceutical, papermaking, dyes, etc. for scientific research and teaching purposes. Our factory produces a series of contact angle measuring instruments, and provides different models of instruments according to the different needs of users.

　　Dynamic contact angle measuring instrumentExamples of specific application areas:

1. During the metal welding process, check the adhesion of the flux to the metal;

2. The adhesion between ink, metal, and paper in the printing industry;

3. Study on the adhesion degree between adhesive and solid;

4. Measurement of wetting degree of aircraft substrate by airborne rain and fog in the aerospace industry;

5. Measurement of the contact angle between shrapnel in air and rain and fog in military science;

6. Measurement of the advance and retreat angles of solid additives injected into crude oil during the process of oil extraction;

7. Measurement and study of wettability between nanomaterials and different active agents;

8. Determination of hydrophilic angle of aluminum foil;

In short, the wide range of applications of this instrument cannot be exemplified here.

Main Features

　　1.High precision spindle:

The CA contact angle spindle is an imported component manufactured using American technology. The contact angle spindle is the most important and critical component of this instrument, and precision machining ensures that there is no shaking, deflection, backlash, or noise during rotation. Domestic conventional equipment cannot achieve it. In addition, it is necessary to ensure high positioning accuracy, heavy load capacity, long service life, small size, and beautiful appearance.

Technical specifications: Circular scale of 3600

Zui small scale 10

Rotation accuracy 0.005mm

Drive Method: DC Motor Software Connection Drive

Carrying capacity 5kg

　　2. Innovative microscope:

Due to the operator working under the microscope for a long time, their eyes are extremely tired from exposure to light, resulting in symptoms such as eye pain and headache after work. So our company has undergone significant reforms to the ancient microscope, adopting a metal external reading disc reading eyepiece structure to overcome the above-mentioned drawbacks of continuous operation.

　　3. Droplet adjuster moving mechanism

The old contact angle measuring instrument adopts a gear rack structure and is a conventional machining program, which makes it difficult to ensure that vibrations occur during movement and run out of the field of view, making it impossible to measure. The high-precision XY dual coordinate micrometer parallel moving mechanism produced by our company has high precision, smooth movement, no vibration, soft operation, and no noise.

Technical specifications: Travel distance 0-25mm (optional)

Linear series steel balls for guide rails

Accuracy 0.005mm

Drive position center

Load capacity of 2kg

Table size 34 × 34

　　4. Workbench

The CA contact angle worktable adopts our company's self-designed coaxial dual drive structure. By operating different handwheels on the same axis, the worktable can move left, right, front, and back, reducing the frequency and workload of operators changing left and right hands during operation.

　　5. Overall structure

The CA contact angle measuring instrument adopts a building block structure as a whole, and various experimental methods and operating methods can be implemented by replacing different components.

In short, there are many characteristics that cannot be introduced one by one and can only be based on the order requirements
