Volatiles during Thick Layer Curing and Curing
This test is used to assess the impregnated resin material after curing. Thick layer curing is indicated by the conditions of the interior, upper surface and lower surface of the specimen after curing. This method can also be used to determine the volatiles during the curing process. A.1 Equipment
The following equipment is used:
A straight and smooth square aluminum foil with a thickness of 0.1mm to 0.15mm and a side length of (95±1)mm; a mold made of metal or any other suitable solid material with a side length of (45±1)mm and a height of (25±1)mm; an oven with forced air circulation and a ventilation rate of at least 8 times/h. The oven should be a model specifically used for curing or drying specimens;
A balance with an accuracy of 0.01g.
2 Sample
Clean the aluminum foil thoroughly and use a mold to make a square box with a side length of 45mm. Then dry it at a temperature of (110±5)℃ for (10±1)min, cool it and store it in a desiccator. Take out the square box and weigh it accurately to 0.01g (m), and use the square box to weigh (10±0.1)g of resin sample, accurate to 0.01g (m).
The sample is cured according to the curing temperature and curing time agreed by the supplier and the buyer. After curing, put the sample in a desiccator to cool to room temperature, and then weigh it accurately to 0.01g (m\). Then remove the aluminum foil. A.3 Procedure
Sample Grade
The sample should be evaluated according to the condition of its top, bottom and inside after curing. Its appearance and viscosity should be visually inspected and indicated by the symbols in Table A.1, Table A.2 and Table A.3 below.
Volatiles should be calculated according to the following formula:
E=100×[(mz-m)/(mz-m)]
Top surface condition
Bottom surface condition
Hard as keratin, machineable
Leathery
Rubbery
Gel-like
The sample contains
No bubbles
No more than five bubbles
More than five bubbles
Degradation A.3 Internal condition
For the condition of the inside of the sample, it should be additionally stated whether the middle part is uniform or non-uniform. Note: In order to illustrate the machine performance, it may be necessary to bend the sample with fingers or cut the sample with a knife. GB/T15022.4—2009
