1.Production process of EVA anti-abrasion agent applied in shoe sole:
The production process of sole EVA anti-abrasion agent is a complex and precise control process, which mainly includes the following key steps:
Raw material preparation:
The main raw materials for EVA wear-resistant include ethylene vinyl acetate (EVA) particles, as well as other additives such as oil resistant agents, nitrile rubber, fillers, foaming agents, coupling agents, zinc oxide powder, stearic acid, etc.
These raw materials need to be prepared in specific proportions to ensure the performance and stability of the wear-resistant agent.
Mixing and mixing:
Put EVA particles and additives into the mixer for thorough mixing, ensuring that various raw materials can be evenly distributed.
Through the internal mixing process, the raw materials are made to achieve a certain viscosity and uniformity, preparing for subsequent granulation and foaming.
Granulation:
Granulate the mixed raw materials to form a granular substance suitable for subsequent processing.
The granulation process requires controlling the size and shape of particles to ensure that they meet production requirements.
Foam:
Put the raw material after granulation into the foaming machine for hot melting to make it viscous.
By controlling the temperature and pressure of the foaming machine, the raw materials are foamed in the mold to form a wear-resistant agent with a porous structure.
Cooling and Curing:
After foaming is completed, the mold is sent to the cooling chamber for rapid cooling treatment, allowing the wear-resistant to quickly cool and solidify.
The cooling process requires good control of time and temperature to ensure the performance and stability of the wear-resistant.
Post processing and inspection:
After curing, remove the wear-resistant for trimming and polishing to remove unevenness and burrs.
Conduct quality inspection on wear-resistant agents, including testing of hardness, elasticity, wear resistance and other indicators, to ensure that they meet production requirements.
Packaging and storage:
Package the qualified sole EVA anti-abrasion agent to prevent contamination or damage during transportation and storage.
Store in a dry, cool, and ventilated place, avoiding direct sunlight and high temperatures.
2.How xiangxie check sole EVA anti-abrasion agent:
A. Sample preparation and labeling
Sampling: Use a sampling tank for sampling, ensuring that the sampling tank is labeled and covered with two layers of sampling plastic bags.
Sampling operation: Unscrew the cover of the sampling port, first release a portion of the raw materials that are stuck in the front section of the sampling port, and then sample as needed (usually 1/3 of the sampling bag). After completion, tighten the sampling plastic bag and select the lid of the sampling tank to complete the sampling process.
B.Appearance and basic performance inspection
Appearance inspection: Check the appearance of the sole EVA anti-abrasion agent to ensure that there are no stains, impurities, consistent colors, and no obvious color differences.
Basic performance testing:
Size and thickness: Use a micrometer with an accuracy of 0.01mm to measure the thickness, ensuring compliance with the agreed thickness, with an allowable tolerance of ± 0.03mm.
Translucency: According to the transmittance testing method, the size of the adhesive film is 50mm x 50mm. After crosslinking and curing under specific temperature and pressure conditions, the transmittance is measured using a transmittance tester, and the value is not less than 90%.
C.Wear resistance test
Wear resistance is a key indicator of sole EVA anti-abrasion agent, which can be tested using a professional wear testing machine. The specific steps are as follows:
- Sample preparation: Prepare a sample of sole EVA anti-abrasionagent according to standard requirements.
- Test condition setting: According to the requirements of the testing machine, set appropriate parameters such as load, speed, and time.
- Experimental operation: Place the sample on the testing machine and conduct a wear resistance test according to the set conditions.
- Result recording: After the experiment, record the wear amount or depth of the sample.
- Analysis and recording of inspection results
Data analysis: Analyze the test results and compare them with standard or reference values to determine whether the performance of sole EVA anti-abrasion agent is qualified.
D.Record keeping: Record the inspection results in detail, and save relevant data and files for future reference and traceability.
