    Abstract: A process produces a block of polyolefin material with uniform crosslinking, which may be uniform between and within polymer chains in the polyolefin material. Steps include: providing an oven; placing the block into the oven; preheating the block to a uniform temperature above the melting point; further heating the block to a temperature at least 30 degrees Centigrade above the melting point; cooling the block to room temperature under an inert gas; and removing oxidized material from surface of the block. Optional steps include: subjecting the block to radiation before placing the block into the oven; removing the gases from the oven on a continuous or stepwise basis; controlling the purge gas flow out of the oven; and determining a heating time period for the block by subjecting control blocks to the same process and analyzing them after various heating times.

    Abstract: A CPU provides a fluorescent light detecting head with an irradiation instruction, in response to which the fluorescent light detecting head irradiates an ultraviolet ray for detection on an ultraviolet curing resin material to be examined. The CPU then acquires from the fluorescent light detecting head an intensity of a fluorescent light emitted from a photo polymerization initiator included in the ultraviolet curing resin material when receiving the ultraviolet ray for detection. The CPU retrieves a predetermined number of past data of the intensity of the fluorescent light from a storage unit and performs a (moving) average calculation processing to calculate the intensity of the fluorescent light at the current time. The CPU performs an estimation processing of a state of the ultraviolet curing resin material based on the calculated intensity of the fluorescent light.

    Abstract: By utilizing a pH indicator having known color change characteristics, an accurate determination of the pH of a binder surface, and hence the amount of cure of a polycarboxylic acid based binder on the fiberglass fibers, can be easily determined for polycarboxylic binder based fiberglass materials used in insulation and composite applications. Based on these results, the manufacturing line used to make these bindered materials may be adjusted to ensure adequate curing at maximum efficiency while minimizing operating costs and reducing waste.
