Author：nylon coated stainless steel wire

The safety of nylon-coated stainless steel wire needs to be evaluated from four dimensions: material properties, process quality, application scenarios and testing standards. The following is a specific analysis:

1. Material basic safety assessment

Chemical stability of the substrate

Stainless steel wire must meet food grade standards, and its nickel and chromium content should meet international standards to ensure corrosion resistance and avoid metal ion precipitation during long-term use.

The acid, alkali and salt spray resistance of the substrate must be verified by a third-party testing agency to ensure that no corrosion occurs in a humid or chemical environment.

Coating component safety

Nylon coatings should pass food contact safety certifications such as FDA and LFGB to ensure that no toxic monomers remain and to avoid the release of harmful substances at high temperatures.

The content of additives such as plasticizers and stabilizers in the coating needs to be tested to ensure compliance with environmental regulations and avoid the migration of harmful substances.

2. Process and quality control evaluation

Coating adhesion and integrity

The bonding strength between the coating and the stainless steel substrate is tested by cross-hatching method, pull-out test, etc. to ensure that there is no risk of peeling of the coating.

Use a microscope to observe the coating surface to detect defects such as pores and cracks to avoid corrosion of the substrate caused by medium penetration.

Durability test

Accelerated aging test is performed in simulated use environment to evaluate the performance attenuation of coating under ultraviolet, high temperature and high humidity conditions.

The wear resistance of coating is verified through friction and wear test to ensure that the coating is not easily damaged during dynamic use.

3. Application scenario adaptability assessment

Temperature adaptability

Clearly define the use temperature range of the product, avoid using it at high temperature, prevent softening, decomposition of coating or degradation of substrate performance.

In high temperature application scenarios, high temperature resistant nylon coating should be selected and its chemical stability at high temperature should be verified.

Medium compatibility

Select the appropriate coating type according to the use environment, such as special nylon coating resistant to chemical corrosion in strong acid and alkali environment.

In food contact scenarios, the stability of coating in acidic and oily media should be verified to avoid material migration.

4. Testing and certification system assessment

Standardized testing

Testing is carried out according to national standards, covering sensory requirements, physical and chemical indicators, etc.

Salt spray test, wet heat test, etc. are carried out by professional institutions to evaluate the corrosion resistance and environmental adaptability of products.

Certification and labeling

The product should have clear safety certification labels, such as FDA certification marks, food contact safety labels, etc., to facilitate user identification.

Provide detailed product instructions to clarify usage conditions, maintenance methods and safety precautions.
