Introduction
Three kinds of polypropylene pipeline construction materials (PP-R, PP-B, PP-H) with different structures, properties and applications are also different. Currently polypropylene
Ene pipe, tube products exist aliasing in the material identification, especially mislabeled as PP-R pipes, pipe fittings more serious problem. E.g
Nominal PP-R, and in fact is another material or blends. The main criteria for this problem, the establishment of material identification method.
Taking into account the interference blending and the use of additives, the application of this standard, the parameters are in line with the characteristics of the sample evaluation can be
For judgment, and for the test results are only partially consistent with the evaluation or analysis of the sample data in the critical value, we need to be careful.
Several representative reference spectrum and characteristics of indicators see Appendix blended sample A, can provide some degree of reference for material discrimination. according to
According to this standard, can be identified polypropylene pipe, tube material whether the PP-R, PP-B or PP-H in one, but not for blending material
Material composition analysis.
During the analysis, due to the factors of the instrument, sample processing conditions may lead to infrared spectroscopy, differential scanning calorimetry curve to produce subtle difference
Do so before the unknown sample analysis, preparation of a set of reference spectra on the same instrument is appropriate.
Polypropylene (PP-R, PP-B, PP-H)
Pipe, tube material identification method
1 Scope
This standard specifies the use of infrared spectroscopy and differential scanning calorimetry, the main raw material for polypropylene (PP-R, PP-B or PP-H)
Identification of the material of the pipe, fittings, and gives sample preparation and spectral interpretation guidelines.
This standard applies to pipes from a single polypropylene resin (PP-R, PP-B or PP-H) made of material discrimination pipe fittings, polypropylene resin
You can also refer to use.
This standard does not apply to pipes made of blended resin, material discrimination pipe, does not apply to β-PP material.
