Embodiment Construction

[0016] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0017] The present invention provides a test method for halogen-free materials, including a complete digestion test and a halogen test, and the complete digestion test includes the following steps:

[0018] Step 1: First, the halogen-free material is pretreated and weighed, and then the lead, cadmium, and mercury in the halogen-free material are digested with a microwave digestion instrument and an electric heating plate acid, and then the digested lead, cadmium, and mercury are filtered. After dissolution, the test data can be obtained by AAS and ICP-OES, and the unfiltered dissolved ones are filtered twice until completely dissolved;

[0019] Step 2: Solvent extraction of polybrominated...

Abstract

The present invention provides a halogen-free material testing method, which comprises complete digestion testing and halogen testing, wherein the systematic detection is performed on lead, cadmium, mercury, polybrominated biphenyls, polybrominated diphenyl ethers, hexavalent chromium and halogen in the halogen-free material through the complete digestion testing and the halogen testing. According to the present invention, the operation process is provided so as to optimize the halogen-free material detection method, improve the work efficiency, and achieve the accurate testing result.

Description

technical field [0001] The invention relates to the field of low-smoke halogen-free cables, in particular to a method for testing halogen-free materials. Background technique [0002] Halogen-free material is a core insulation material or sheath material for flame-retardant cables. It is an important material for manufacturing low-smoke halogen-free cables. Lubricant and other additives are mixed, plasticized and granulated, and no toxic fumes will be emitted when burned. With the rapid development of my country's economic construction and the improvement of safety performance requirements, people pay more and more attention to green and environmental protection. Modern equipment requires the use of low-smoke, halogen-free and flame-retardant wires and cables, and the demand for low-smoke, halogen-free cables is increasing. The bigger it is, the halogen-free materials are usually tested before use to see whether certain material components exceed the standard and whether the...
