Purpose and Application

Electric grid tester430PType is a universal instrument used for conducting various scratch and scratch resistance tests on paint and plastic surfaces. For test pieces of different thicknesses, single or multiple engraving knives can be used for parallel and cross engraving(Transfer the sample90° ).

430PSpecially designed for all users, the adhesion test is conducted using the cross cutting method according to the standard, and is carried out in accordance withGME 60 280Conduct scratch resistance test. The wide range of experimental parameters and multiple selection of experimental tools make these experiments easy to conduct.

430PThe test results have good reproducibility and are accurate and reliable.

Design and functionality

430PThe cross grid tester is a desktop instrument with a sturdy structure that can ensure the stability and reliability of cutting tools even under harsh conditions. The experimental process consists ofPLCControl, all parameters(Scratching speed, engraving length, cross engraving mode)Can be set with buttons. Each exercise program(Test piece transfer, engraving position, and required pressure adjustment)All are driven by independent stepper motors.

During the experiment, the sample moves in a straight line at a constant speed. Press the cutting edge onto the sample with the required pressure(The biggest50 N)The transmission guide ensures that the test blade tip is pressed onto the test disc according to the specified requirements. The supply scope includes two control boards for different cross engraving modes, which are easily interchangeable.

430PThere are two types of electric grid markers, manual or motor-driven to adjust pressure. The manual test pressure adjustment is simple and accurate. The motor-driven pressure regulating instrument can also be tested by gradually increasing the pressure. The pressure required to achieve thorough engraving can be determined during the trial scratch.

Cross scratch test

430 PThe type can be tested according to general standards,(Summary in the table)No need for additional programs. The following cross carving methods can be selected(Number of cuts x cutting distancemm).2×5，6×1，6×2，6×3，8×1，8×2，11×1，11×2.

In the trial scratch, the load requirement for cutting the coating onto the substrate can be identified. stay430P-IIType machine(Motor driven pressure regulation)This requirement can be easily achieved through an automatic trial run.

When analyzing some standards, adhesive tape should be used for peeling. Adhesive tape will also be supplied to customers as accessories to meet their needsEN ISO 2409(Tape width25 mmAdhesive force10±1N)requirement. The scope of supply includes one2.5A magnifying glass is used to evaluate the engraving. In most standards, the appearance quality can be measured using the standard scale(Scratching rules)Compare visually.

Although adhesion tests using scratch methods can be compared with each other, they are not suitable for comparison with the results of other testing methods(For example, vertical detachment testEN 24 624)Because they are different processes.

The Yilixin product catalog provides the following models for adhesion and peel testing.

●525Type adhesion tester(Manual/affordable)

●525 MCType adhesion tester(Electric/battery driven)

●513 MCType adhesion tester(Electro hydraulic/AC power operation)

Scratch resistance test

accord withGME 60280The scratch resistance test is conducted by selecting a blade with a diameter of1 mm, predetermined grid spacing(20Blade blades, spaced apart2 mm)The pressure is the same as the grid test5N, speed1Meter per minute.

When analyzing the scratch resistance test, compare the shell degree difference △ with the undamaged plastic surfaceLLighting can meet this requirementD65Light source, measuring geometric anglesd/8Measurement hole φ27 mm.

Special experiment

DifferentGME 60 208Alternatively, other methods may be used to modify the scratch resistance test

- Test blade head(Garden bead tool0.5 mm、 φ0.75 mm、 φ3 mmAs an accessory supply)

- Test load(2 ~ 50 N，2NProgressive or using weight kits,1 ~ 10 N，1NProgressive supply as an attachment)

For the grid test and scratch resistance test, the program setting mode can be used for any test setting, with the maximum side length40 mmThe distance between the knives can be set to0.5 mmmultiple. To minimize the testing time, it is common to use cutting tools with the smallest length and corresponding connecting accessories.
