Embodiment Construction
[0019] A detection method for wrapped oil, characterized in that: comprising the following steps:
[0020] Step 1, use a colorimeter to measure the L of the unwrapped oil DAP 0 value and b 0 value;
[0021] Step 2, wrap the DAP that has passed step 1 with wrapping oil;
[0022] Step 3, measure the L value and b value of the DAP through step 2 with a colorimeter;
[0023] Step 4, calculate △L=L-L 0 and △b=b-b 0 value;
[0024] Step 5: Determine whether the quality of the wrapped oil is qualified by the following method: △L>-2.0 and △b>-2.0, it is determined to be qualified, and △L≤-2.0 and △b≤-2.0, it is determined to be unqualified.
[0025] The present invention will be further described below in conjunction with the embodiments, and the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other used embodiments obtained by persons of ordinary skill in the art without crea...
