Building curtain wall aluminum plastic board refers to a composite board for building curtain wall materials, composite plates with plastic as the core layer, two sides as aluminum plates, and decorative and protective coating or film on the surface of the product as the product as the product as the product. Decorative surface. Nowadays, the quality requirements of new materials in the field of construction and decoration are becoming more and more strict, and manufacturers have also continuously regulated their quality control methods and means on this requirement. GB/T17748-2008 The national standards for the "Aluminum Plastic Composite Plate of the Building curtain Wall" make specific regulations on the quality control indicators and detection methods of aluminum-plastic composite boards.
1. Color difference detection
According to the standard requirements, the color difference detection uses the visual inspection method, and it is stipulated that it should be carried out under the natural light conditions of non -sunlight. However, because the lighting conditions are not regulated, the judging results are often different due to environmental differences.
Second, aluminum thickness, composite adhesive film thickness and deviation detection
1. The thickness test of aluminum material
According to the standard GB/T 17748-2008, remove the aluminum material from the sample as the test piece, and measure the thickness of the aluminum material with a minimum score value of 0.001mm (1 μm). A test point of more than 5 angles and the center part, with the minimum average and arithmetic average of all measurement values as the test results.
2. Compound adhesion film (polymer film) thickness test
Compound adhesion thin-film thickness test refer to the measurement of GB/T 6672-2001 plastic film and thin tablet thickness (mechanical measurement method) standards. Measurement of the thickness and thickness deviation of thin film (polymer film).
Third, coating glitter bias test
According to the GB 9754 standard, the test work is required to use the 20 -degree luster. Test data at as many positions as possible during testing, and use the difference between the maximum value and minimum value in the test data as the bias of the gloss of the gloss of the coating of the aluminum -plastic composite plate for the building curtain wall.
Fourth, the peeling strength detection building curtain wall aluminum plastic panel peeling strength is very important. The composite strength between aluminum plates and plastic can meet the standards to maintain durable and stable performance in subsequent use.
The test is as follows:
Peel off the aluminum that is to be peeled off at both ends of the sample. One of them is cut off one end to intercept the core and aluminum materials behind, clamp the left aluminum on the top of the plywood and test with the test with the test with the test. The top of the machine is connected, and the aluminum peeled on the other end is sandwiched on the drum. The length axis of the test piece is vertical with the central axis of the drum, the test machine carrier is clear, and then connects the lower splint to the lower pinch of the test machine (please see the attachment); , Until the test piece is peeled at least 150mm, and the peeling force and the itinerary curve are recorded. Although in the standard, although the sample preparation has been provided in detail, it is inevitable that during the processing process of the sample, it will inevitably affect the front and back of the test parts. In the effect of the test results, the test machine should have the function of "hoe to the end".
In addition, the XLW intelligent electronic tensile test machine can also take into account the 180 ° departure intensity of 180 °, the peeling strength of the roller, the stretching strength and the elongation of the erection of the aluminum -plastic composite composite plate production of aluminum -plastic composite plates Test.
Fifth, aluminum -plastic composite plate production composite adhesive film (polymer film) tear strength detection
GB/T17748-2008 "알루미늄 플라스틱 복합 보드를위한 커튼 월"국가 표준은 고 분자 필름의 눈물 강도 테스트를 오른쪽 각도 강도로 말합니다. 그 실행 방법은 GB/T11999 "플라스틱과 얇은 눈물이기 때문입니다. 저항 성능 Elmendor의 실험 방법 "이므로 강도를 찢어 내기 위해 Elimodorf 방법이라고합니다. 테스트는 테스트 중에 "Sly-S1 Tear Meter"로 테스트 할 수 있습니다.
위의 것은 건물 커튼 월의 탐지 방법 및 탐지기에 대한 간략한 소개입니다. GB/T17748-2008의 관련 탐지 방법의 요약을 통해, 다양한 내용의 내용은 주로 GB/T 2790-1995 접착제 180 ° 껍질을 벗기기 강도 테스트 방법으로 언급된다. (강성 재료 결정), GB/T 6672-2001 플라스틱 필름 및 얇은 정제 두께 측정 (기계적 측정 방법), GB/T 1199-1989 플라스틱 및 얇은 찢어진 저항 테스트 방법 (Elmendorf 방법), GB/T 13022-1991 플라스틱 필름 스트레칭 성능 테스트 방법 및 기타 관련 표준.
