2. 10 sets of samples are simultaneously foamed/oiled

3. Measure the density value and volume value of the sample after foaming/soaking in oil, press the read button, and immediately print an A4 data report (the report contains content: density value, volume, foaming rate/volume/mass change rate, etc.)

Function introduction

1. Equipped with MAYZUN-Smart analysis system, without any calculation, 2-step operation, 5 seconds to accurately and quickly measure such as: rubber plastic blocks, PVC/PP/PE plastic particles, polyurethane foam, silica gel/asphalt glue and other solids , Density and specific gravity of granular, floating and colloidal materials;

2. Using DIN and AKRON Aker abrasion test methods, it can be used to detect DIN abrasion, AKRON Akron abrasion volume and abrasion index of materials such as automobile tires, rubber, conveyor belts, and EVA shoe materials;

3. According to (JIS-K-6258) and (ISO1817) standards, it can be used to detect the mass change rate and volume expansion rate of oil seals of rubber materials such as vulcanized rubber, rubber seal rings, and oil rings;

4. For foam plastics such as polyurethane, polypropylene PP, polyethylene PE, EPS, etc., the foaming ratio and quality change rate can be measured;

5. It has the function of compensation setting of solution temperature and density, and distilled water or tap water can be used as the measuring medium;

6. The design of an integrated water tank and lightweight hanging railing line can greatly reduce the measurement error caused by air buoyancy;

7. Touch screen operation greatly simplifies the user's measurement steps, and can store each measurement result, and print a Chinese measurement report with one key

Brief introduction of MAYZUN-Smart analysis system (volume expansion rate of change):

Purpose

Used in occasions where the efficiency of measuring the mass change rate, volume expansion change rate and density of rubber sealing rings needs to be greatly improved.

Principle

The German HBM load cell sensor is used as the main sensing component, the Archimedes buoyancy method principle is applied, and the PC-side data processing software is combined to accurately and efficiently measure the mass change rate and volume of automobile rubber O-rings. Expansion change rate, density.

Application scenario analysis:

In production, the quality inspection parameters of rubber O-rings for automobiles mainly include: mass change rate, volume change rate, hardness change rate, tear strength change rate, elongation change rate, etc. To calculate the rate of change of the above various parameters, it is necessary to measure the above parameters first, and then place them in 1# oil (aviation gasoline) at 150°C for 70 hours, and finally compare the various items before and after cooking. Changes in parameters. Taking the detection of the quality change rate and volume change rate of the oil seal of rubber O-rings as an example, the conventional instruments currently on the market for testing the quality change rate and volume change rate of the oil seal are made according to the experimental standards. It takes 70 hours. If 4 samples are to be measured, one instrument will take 280 hours (about 11 days). Such measurement efficiency is too low.

In order to improve the measurement efficiency, our company has specially developed a measurement system (as shown in Figure 1 below). The system only needs to be based on our company’s original testing equipment and equipped with microcomputer multi-sample measurement processors to achieve simultaneous The function of measuring multiple sets of samples. At the same time, you can also equip with a micro printer to print the measurement results into a professional report. Compared with the measurement results manually recorded before, the printed measurement report will be more professional and useful in front of the customer. Persuasive. Of course, you can also customize some functions, such as: you need to permanently save each measurement data for later query, analysis, printing, etc.; you can also connect the measurement result data with the enterprise's ERP, OA and other systems , Realize experiment and production data sharing.
