I want to test the abrasion, corrosion resistance and acid and alkali resistance of polyurethane resin. I do n’t know how to test it. Can friends provide the test standard number?

The abrasion resistance
is performed in accordance with 6.10 in GB/T17748-1999, and the nine abrasion and flatness of the three samples are worth the test results.
The acid resistance, alkali resistance, oil resistance
. According to the regulations of 6.11 in GB/T17748-1999, the person with the worst performance in three samples is the test result.

The polyurethane resin, as a polymer material with high strength, tear resistance, wear resistance and other characteristics, is widely used in daily life, industrial and agricultural production, medicine and other fields. It is used to prepare polyether -type polyurethane. The polymerization method vary with the nature of the material. When synthetic elastic body, prepare a low molecular quantum melol, and then react with the excess aromatosyl alcohol to generate the prefabricated cluster with isocyanate as the end -based, and then expand the dilate to obtain the thermoplastic elastic body; Expand the chain and further cross -linking to obtain casting elastomers.

The wear -resistant materials are new materials with special electrical, magnetic, light, sound, sound, heat, force, chemistry, and biological functions. They are high -tech fields and national defense construction of information technology, biotechnology, energy technology and other high -tech fields and national defense construction. Important basic materials also play an important role in the transformation of certain traditional industries, such as agriculture, chemical industry, and building materials.
Thenod resistance has a variety of types and extensive uses. It is forming a large -scale high -tech industrial group, which has a very broad market prospect and extremely important strategic significance. The wear -resistant materials can be divided into microelectronics, optoelectronic materials, sensor materials, information materials, biomedical materials, ecological environment materials, energy materials and machine -sensitive (intelligent) materials. Since we have taken electronic information materials alone as a type of new material field, the new wear -resistant materials referred to here are the main wear -resistant materials other than electronic information materials.
