Plaster electronic peeling test machine

Core Features

• Professional medical heart rateSpecially designed for the testing requirements of plaster and patch products, it can accurately simulate their peeling process from simulated skin or standard test boards, and the test results are more in line with the actual clinical experience.

• High precision micro force measurementUsing high-sensitivity force sensors and precision measurement and control systems, the measurement accuracy is as high as 0.5% F.S. It has excellent measurement accuracy and repeatability for the common low peel force (ranging from millinewtons to several newtons) of plaster patches.

• Intelligent operation and displayEquipped with a 7-inch color HMI touch screen, the operation interface is intuitive and friendly. It can display the complete displacement curve of peeling force in real time, and automatically calculate key data such as average peeling force and peak value, making the testing process clear at a glance.

• Stable and reliable transmissionUsing precision ball screw transmission and high-performance drive system, the peeling speed is infinitely adjustable within the range of 1-500 mm/min and runs smoothly. The speed control accuracy is high, meeting the standard testing requirements.

• Multi functionality and safetySupports multiple testing modes such as 180 ° peeling and T-shaped peeling. The device has complete limit and overload protection functions, and is equipped with a micro printer that can instantly print test reports with detailed data and curves.

Test Principle

Plaster electronic peeling test machineWork according to standardized adhesion testing principles. Firstly, stick the plaster sample onto a standard stainless steel plate or a specific simulated skin substrate according to the specified conditions (such as time and pressure). Subsequently, fix the test board in the lower fixture of the instrument and clamp the free end of the plaster sample flat on the upper fixture. After the test is started, the upper fixture moves upwards at a constant speed to peel off the plaster from the substrate. The integrated force sensor continuously records the resistance changes during the peeling process, and the system synchronously draws the peeling force curve and automatically calculates the average peeling strength (unit: N/cm or N/25mm), thus scientifically quantifying the initial adhesion performance of the plaster product.

• Modern BabuAccurately measure the peel force between the Babu base material and the anti adhesive layer or simulated skin, providing key data for optimizing the matrix formula.

• Medical fixed dressingsTest the adhesion performance of postoperative adhesive tape, infusion tie, etc. to ensure their safety and effectiveness in clinical use.

• Transdermal drug delivery patchEvaluate the initial adhesion of a new transdermal patch and study its adhesion properties to the skin.

• Production enterprises and quality inspection institutionsIt is an important tool for plaster production enterprises, drug research and development institutions, and third-party testing centers to conduct product factory inspection, formula screening, process validation, and raw material quality control.

Detailed explanation of testing process

Standardized operations are a prerequisite for obtaining accurate and reproducible data, and the standard process is as follows:

1. Sample preparation and bondingCut the plaster product to a standard width (such as 25mm). After removing the anti sticking lining, stick it flat on a clean standard test board according to the pressure, time, and temperature conditions specified in the standard.

2. Parameter SettingsSelect or set the testing method on the touch screen, input parameters such as sample width and testing speed (usually 300 mm/min).

3. Sample clampingFix the test board with the pasted plaster on the lower fixture platform, ensuring that the pasting surface is facing upwards. Flatten the free end (or pre peeled end) of the plaster into the upper fixture.

4. Test ExecutionStart the device and move the upper fixture upwards at a constant speed for peeling. The instrument real-time draws and displays the peeling force curve.

5. data analysisAfter the test is completed, the system automatically calculates the average peeling force and the range of force values. Users can view, store data, and print complete test reports including curve graphs.

The Importance of Quality Control

For plaster products, peel strength is one of the core indicators to measure their performance, which directly affects patient experience and treatment effectiveness. Insufficient peeling force may cause the plaster to accidentally fall off during movement, affecting the sustained release of the medication; Excessive peeling force may cause pain or even skin damage during peeling. passPlaster electronic peeling test machineBy conducting objective and precise laboratory tests, enterprises can scientifically evaluate and adjust pressure-sensitive adhesive formulations, optimize coating and composite processes, thereby stabilizing product quality, ensuring that products have sufficient adhesion strength and comfortable peeling, meeting drug regulatory requirements and market expectations.
