Testování vlastností světlem tuhnoucích pryskyřic
A photocurable resin is a polymer material whose curing process is catalyzed by a photoinitiator under ultraviolet or visible light. Light curing resin is usually a single component material, to znamená, it only needs to be coated on the substrate, through ultraviolet or visible light irradiation, can achieve rapid curing of the coating in a few seconds or minutes. Light curing resin has excellent heat resistance, chemical resistance, wear resistance and aging resistance, and has the advantages of low cost and easy to use, which is widely used in the coating and manufacturing process of 3D printing, elektronika, optics, printing and other fields.
Test of performance
| Výkon | Item of inspection |
|---|---|
| Degree of cure | The degree of coating curing |
| Stupeň viskozity | Viscosity of paint |
| Tvrdost tvrdosti | Hardness of coating |
| Resistance to abrasion | Abrasion resistance property |
| Resistance to chemicals | Acid and alkali resistance, solvent resistance, atd |
| Průhlednost | Transparency of coating |
| Hustota hustoty | Density of paint |
| Resistance to heat | High temperature resistance |
| Odolnost vůči počasí | Uv resistance, odolnost proti korozi, atd |
| jiný | Such as antistatic, antibacterial and so on |
The results of these test projects can help to evaluate the quality and suitability of the photocurable resin and how well it will perform in practical applications. The test method and equipment are different according to the specific type of light curing resin and the test item.
Testování vlastností světlem tuhnoucích pryskyřic
Způsob detekce
Curing degree: Use microscope, infrared spectrometer and other equipment to test the curing degree of the coating.
Viskozita: Use viscometer and other instruments to measure the viscosity of the paint.
Tvrdost: Use Rockwell hardness tester, Babbitt hardness tester and other equipment to test the hardness of the coating.
Odolnost proti opotřebení: the wear resistance of the coating is tested by grinding wheel wear test and pencil hardness test.
Chemická odolnost: Use acidity meter, alkalinity meter, solvent immersion and other methods to test the acid and alkali resistance of the coating, solvent resistance, atd.
