Tips: Experts teach you to use safety shoes correctly, effectively avoid opening rubber to extend protection life

The two main parts of the safety shoes are the upper and the bottom, and the upper and the bottom must be combined into shoes, which must be treated with glue and then combined in one way by PU infusion, cold sticking, and suture. Therefore, the main reason for opening the glue is related to the selection of raw materials, the use of glue, and the manufacturing process. After the shoes are worn for a period of time, due to the continuous twists and turns, there is likely to be a small area of ​​plastic, and the same applies to safety shoes. How to avoid opening a large area of ​​safety shoes to extend the life of safety shoes, from the production of safety shoes and consumer use of the two aspects of analysis.

1) The reason for the production process of safety shoe opening glue:

1. Improper upper treatment: Improper use of treatment agents and glue, different cortical materials need to be tested with treatment agent and glue,

Only qualified for adhesion can be used. The upper was not polished and did not completely destroy the cortical surface;

2. Improper handling of the bottom: the treatment of the treatment agent and the glue treatment are not in place, and the bottom polishing is not in place;

3. Improper use of treatment agent and glue: Incomplete drying, insufficient curing agent in glue, too much glue;

4. Crimping: If it is cold-adhesive, the surface and the bottom are well-fitted, and the sufficient pressure and pressing time must be ensured.

2) Personal use reasons for safety shoes to open rubber:

1. No proper maintenance;

2. Do not touch the rain for a long time, and do not wash it in water for a long time;

3. The protective footwear glue is easy to open plastic glue, not easy to expose to the sun or contact with heat;

4. It is not easy to contact with chemicals for a long time (unless specially produced acid and alkali resistant safety shoes);

5. Newly purchased labor insurance shoes cannot be used for a long time.

3) If the safety shoes can be opened, if it can be strictly controlled from the production process, it basically eliminates the problem of open rubber within six months after wearing. Of course, this is not absolute. The following five points need to be noted when using safety shoes:

1. Do not wear the same pair of safety shoes for a long time. It is best to wear them in pairs, which can effectively reduce the number of short-term twists and turns in the same pair of labor insurance shoes, and prevent the opening of plastics due to high frequency of tortuosity.

2. Regular safety shoes maintenance, cleaning, oil, keep the soft and soft leather.

3. Pay attention to the cleaning method. Do not soak for a long time. The soaking time must not exceed 2 hours.

4. The safety shoes after cleaning must not be quickly dried and kept away from fire sources. Do not use heating or open fire, which may cause aging and opening of safety shoes.

5. If you do not wear for a long time, you should first clean the safety shoes, place it in a cool place to avoid mildew. The shoe is best held with a filler to avoid distortion.
