Introduction to the definition and application fields of cross-linking and curing

Cross-linking and curing is a process that combines intermolecular bonds into a stable three-dimensional network structure. In polymer materials, this process is called a cross-linking reaction. Cross-linking improves the stability and durability of materials and makes them stronger and harder. Cross-linking and curing can be achieved by heat treatment, radiation irradiation or the use of cross-linking agents. In many products, such as plastics, rubber, coatings, glues, fabrics and wires and cables, cross-linking and curing is an important process that can improve the functionality and performance of the product.

What are the cross-linking and curing performance indicators?

Cross-linking and curing performance indicators are indicators for evaluating the cross-linking ability of materials, usually including cross-linking density, cross-linking degree, cross-linking time, cross-linking Contact temperature, etc. Among them, cross-linking density refers to the number of cross-linking points per unit volume, which reflects the degree of cross-linking of the material. The degree of cross-linking refers to the percentage of the cross-linked part in the total molecular weight, and can also be expressed by the degree of cross-linking. Cross-linking time and temperature are factors that affect the degree and density of cross-linking, and therefore are also parameters for evaluating cross-linking performance. During the manufacturing, processing and use of materials, the quality of cross-linking and curing properties has an important impact on their performance and reliability.

BAIWhat does the JIAN test report do? What problems can it help you solve?

1. Sales report. (Sales need to provide third-party testing reports to make their products more unique, let the product data speak for themselves, and make customers more confident in the quality of their products.)

2. Research and development reports. (In the process of developing new products, we encountered some thorny issues about ingredients. We used third-party testing data to find the cause of the problem, solve the problem in a timely manner, shorten the R&D cycle, and reduce R&D costs)

3. Improve products quality. (Discover problems with your own products through comparison of third-party testing data, improve product problems, improve quality, and reduce production costs)

4. Use of scientific research paper data.

BAIJIAN testing process

1. Send samples. (Communicate with engineers, submit your own testing requirements and send samples to our research institute)

2. Initial inspection samples. (After receiving the sample, conduct a preliminary inspection of the sample and formulate a detailed experimental plan)

3. Quotation. (After the initial inspection, a quotation will be made based on the customer's testing needs and the complexity of the experiment)

4. Both parties confirm, sign a confidentiality agreement, and start the experiment.

5. It takes 7-15 working days to complete the experiment.

6. Mail the test report and provide post-service.

The above is the relevant introduction to cross-linking and curing detection. If you have other needs, you can consult the laboratory engineer to help you solve it.
