Máy kiểm tra hiện tượng mờ sương FT-F1 được thiết kế chuyên nghiệp để đánh giá đặc tính mờ sương của các thành phần dễ bay hơi trong vật liệu trang trí được sử dụng trong ô tô và máy bay, ví dụ như các sản phẩm nhựa, polyurethane, dệt may, da, chất kết dính, vải không dệt và chất đàn hồi định hình nhiệt ở điều kiện nhiệt độ cao. Nó cũng có thể được sử dụng để kiểm tra hiện tượng mờ sương của đèn pha phóng điện cường độ cao (HID) của ô tô.

Features

Wide range and high precision of temperature control device to support the combinations of non-standard test conditions
6 test stations can perform specimen test or blank test simultaneously
FT-F1 fogging tester ensures accurate and reliable test data through stable running condition

Test Principle

The preconditioned specimen is heated and evaporates in the beaker; the volatile constituents condense on the glass plate or aluminum foil treated in cooling chamber. Take off the glass plate or aluminum foil when the condensation process is finished. The fogging characteristics could be obtained by measuring condensed constituent weight and fogging value on the glass plate or aluminum foil and comparing with the data before condensation process.

Test Standards

This instrument conforms to the multiple international and national standards:
ISO 6452, DIN 75201, SAE J1756, QB/T 2728, BS EN 14288, PV 3920, PV 3015, ES-X83231, NES M0161, D45 1727, GM 9305P, TSM 0503G

Three Test Methods

Gloss Method: the specimen is heated in the beaker and its volatile constituents are condensed on the cooling glass plate. The fogging value could be obtained by calculating and comparing the gloss values occurred before and after condensation process.
Haze Method: the specimen is heated in the beaker and its volatile constituents are condensed on the cooling glass plate. The fogging value of the specimen could be obtained by calculating and comparing the fogging values occurred before and after condensation process.
Weighing Method: the specimen is heated in the beaker and its volatile constituents are condensed on the cooling aluminum foil. The fogging value - the weight of condensed constituents could be obtained by analyzing the weight changes of aluminum foil occurred before and after condensation process.

Instrument Structure

The instrument mainly consists of constant high-temperature bath, constant low-temperature bath, cooling plate, beaker, glass plate, meter, sample cutter and other accessories, through which it can perform the processes of sampling, heating, condensation and test.

Operation Process

Prepare specimens-----switch on high and low temperature baths-----clean beakers and glass plates------place specimens----place glass plate or aluminum foil-----place cooling chamber-----perform test for a specified period of time----take off glass plate or aluminum foil and place certain time----measure the gloss value, fogging value of glass plate or weight value of aluminum foil------compare the data and obtain test results
