VOM detection methods and steps


1.1, the clean aluminum foil into the oven at 100 ℃ oven bake 1 hour;

1.2, the aluminum foil into the dryer, the cooling at room temperature to the aluminum foil weight stability;

1.3, accurately weighed aluminum foil disc and record the weight of M1;

1.4, take the silica gel sample about 10 grams and cut into about 1cm2 size into the aluminum foil plate;

1.5, the sample together with the aluminum foil into the dryer;

(This step is very important to prevent moisture contact with the sample)

◆ The time of this step depends on the indoor humidity, when the weight of the sample for two consecutive weighing the same time, determine the sample is dry

◆ Recommended sample drying time of not less than 12 hours

1.6, accurate weighing aluminum plate + sample weight M2;

1.7, the sample curing process: the sample and the aluminum foil tray together into the oven at 200 ℃ constant temperature 4 hours;

1.8, the vulcanized samples with aluminum foil tray together into the dryer, at room temperature for cooling at least 3 small

Until no change in weight stability;

1.9, accurately weighed and cooled by drying and drying aluminum foil plate + sample and record the weight of M3;

1.10, the formula for calculating the percentage of VOM content is:

% VOM = [(M2-M1) – (M3-M1)] / (M2-M1) x100

Silicone rubber apply in automotive industry

For more than and 10 years, the car has developed in the direction of reducing weight, increasing speed, saving fuel, limiting exhaust volume and improving reliability, and its core is to reduce the size of the engine. After the application of turbocharger, the engine under the hood is getting higher and higher, in 70s for 100 degrees, in 80s to 150 degrees Celsius, in 90s more than 200. Thus, the use of silicone rubber in the key parts of the growing number of.
