DMAIC: Define, Measure, Analyze, Improve, Control. DMAIC drives costly variation from manufacturing and business processes. The five steps in DMAIC are Define, Measure, Analyze, Improve, and Control. Step 1 â Define. The Define phase is about coming up with a focused problem statement and a supporting measure of success or failure.
I just put a couple of inches in the bottom of the pot. Canola oil is inexpensive and has a smoke point of over 400 F (204 C). The melting point of HDPE is in the mid 200 F range but the extrusion temperature range is 350 - 500 F. I uses oil heated on my stove top to a little over 350. Just make sure that the bottle pieces are dry or the water will cause oil to pop out of the pot.
Normally, aspirin melts between 138 and 140 C. The melting point range for salicylic acid is 158 -160 C. At these temperatures, the crystals' lattice energy is broken, and they undergo a phase change from solid state to liquid state.ormally, aspirin melts between 138 and 140 C.
