Features of Safety protective tool box

The Safety protective tool box does not have a standard definition. It literally means it is generally used to store fragile items or valuable equipment. In terms of product performance, the Safety protective tool box has the advantages of being strong and durable, waterproof and dustproof, resistant to high and low temperatures, safe to use, resistant to chemical corrosion, and automatically adjust the internal and external pressure difference. It can withstand wind and rain, resist pressure and impact. Waterproof and moisture-proof, wear-resistant, corrosion-resistant, high and low temperature, and can be used normally in harsh environments, which is worthy of users' trust. In terms of application of safety protection box products, it has a wide range of uses. It can be used as instrument box, equipment box, transportation box, luggage check-in box, medical tool box, etc. The service areas include industry, fire rescue, medical, photography, radio and television, outdoor Etc., adapt to a variety of harsh environments. In this way, putting a series of valuable instruments such as notebook computers, photographic equipment, instrumentation, communication equipment, navigation equipment and so on will not affect its normal use and realize its value in a specific environment.

 

The general Safety protective tool box is made of pp material. Many of you should not be aware of pp raw materials. Here is a brief introduction to the features of the Safety protective tool box?

 

1. Thermal performance

The Safety protective tool box has good heat resistance, can be sterilized at a temperature above 100°C, and will not deform at 150°C without external force. The embrittlement temperature is -35℃, and embrittlement will occur below -35℃, and the cold resistance is not as good as polyethylene. The melting temperature of the PP material of the Safety protective tool box is about 40-50% higher than that of polyethylene, which is about 164-170℃, and the melting point of 100% isotacticity poly is 176℃.

 

2. Chemical stability

The Safety protective tool box has good chemical stability. PP material is relatively stable to other chemical reagents, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can soften and swell the polymer, and its chemical stability As the degree of crystallinity increases, it also improves, so the pp material of the Safety protective tool box has a good anti-corrosion effect.

 

3. Electrical performance

Safety protective tool box has a high dielectric coefficient and can be used to make heated electrical insulation products as the temperature rises. Its breakdown voltage is also high, with good resistance to voltage and arc resistance, but high static electricity, and it is easy to age when it comes in contact with copper.

 

4. Weather resistance

Safety protective tool box is more sensitive to ultraviolet rays. Adding zinc oxide, carbon black or similar milky fillers can improve its aging resistance.
