Prosedur metode deteksi
The following is the performance of polyurethane waterproof coating to be tested and its testing steps:
Construction performance: Use construction performance testing equipment to test the fluidity, brushability, drying time and other construction performance of the coating, dan catat hasil tesnya.
Weatherability: Test the weatherability of the coating using a xenon lamp aging chamber or a spectral radiation chamber, dan catat hasil tesnya.
Tahan air: Gunakan alat uji penetrasi air dan alat uji perendaman untuk menguji ketahanan air pada lapisan, dan catat hasil tesnya.
Bond strength: The coating adhesion to the substrate was tested using the delimiting tester and the stripping tester, dan hasil tesnya dicatat.
Impact resistance: The impact testing machine is used to test the impact resistance of the coating, dan hasil tes dicatat.
Ketahanan aus: Wear testing machine is used to test the wear resistance of the coating, dan hasil tes dicatat.
Warna dan kilau: Uji dengan pengukur perbedaan warna dan pengukur kilau di bawah sumber cahaya standar dan catat hasil pengujian.
Untuk beberapa pelapis khusus, mungkin perlu menggunakan instrumen dan peralatan lain untuk pengujian, dan langkah operasi spesifiknya akan berbeda.
