Semi conductive shielding materials are generally obtained by adding conductive carbon black, such as EVA, EEA, or blended PE. The filling amount of carbon black in semi conductive shielding materials has a significant impact on the conductivity of polymer materials. This article will introduce the application of conductive carbon black in semi conductive shielding materials How to use semi conductive shielding material for testing extruded insulated cables? What are the testing standards and items? Today, BAIJIAN will introduce the relevant content of semi conductive shielding material testing for extruded insulated cables
Where is the testing report done?
BAIJIAN cooperates with nearly a thousand laboratories nationwide, with complete CMA/CNAS qualifications. We can arrange and provide semi conductive shielding material testing services for extruded insulation cables nearby, and provide authentic and effective semi conductive shielding material testing reports for extruded insulation cables What is the testing fee The cost of testing semi conductive shielding materials for extruded insulated cables is determined based on factors such as testing items and laboratory qualifications. BAIJIAN will arrange engineers to confirm the relevant testing content with you before making a quotation
How long is the validity period of the test report?
The validity period of the test report is generally two years, or 6 months beyond the product shelf life.
. The inspection report refers to the product inspection report, which provides the test data and standard compliance conclusions. The conclusions are divided into two categories based on applicability: the test samples are self sent by the enterprise, so the conclusion is only valid for the sample sent. Testing is aimed at a certain batch of products, using attribute sampling or percentage sampling, therefore, the testing conclusion is valid for that batch of productsThe role of conductive carbon black in semi conductive shielding materials
The main function of conductive carbon black is to endow the semi conductive shielding material with conductivity, and the conductivity of the semi conductive shielding material usually increases with the increase of carbon black filling amount, but its conductivity does not proportionally and infinitely increase with the increase of carbon black filling amount.
. When the filling amount is low, there is almost no conductive effectFunction of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
