    Abstract: This disclosure provides a method for producing a cross-linked rubber for the additively fabricated object that can be easily produced with good dimensional accuracy and simplicity, even using a general-purpose uncross-linked rubber composition. This producing method is a method for producing a cross-linked rubber, in which an additively fabricated object of uncross-linked rubber is heated in a liquid to produce an additively fabricated object of cross-linked rubber, wherein the method includes, heating the additively fabricated object of uncross-linked rubber within the range not exceeding the saturated vapor pressure by controlling the temperature and pressure of the liquid, obtaining the equivalent cross-linking amounts at regular intervals from the start of heating using the following Formula (1), accumulating them and calculating the cumulative cross-linking degree, and stopping the cross-linking reaction when the cross-linking degree of the additively fabricated object of cross-linked rubber reaches the required cross-linking degree.

    Abstract: A method for increasing productivity and quality in production of cured polymer by a real time measurement of the progress of curing, in a mould cavity, which being filled with a compound to be cured, wherein a signal is generated by a wave at an ultrasonic or equivalent frequency, which is transmitted through the mould cavity, the time for the wave to pass through the compound in the mould and back is detected, and the detected signal being analyzed in a suitable data processing computer , to establish a graph showing a relationship between the time for the wave to pass through the compound in the mould and back, and the time of the curing of the compound. The graph is used to determine a feature of the compound by identifying at least one specific parameter of the graph, and using said parameter to control the production.

    Abstract: Ultraviolet light having wavelengths of 250 to 380 nm is irradiated to a reaction curable resin. A screen image of luminance value is recorded which is obtained by extracting only a specific wavelength component of the reflected ultraviolet light, and the cured state of an ultraviolet curable resin is quantified from a captured image and displayed. At the same time, the spectral characteristic of reflected light is measured by an ultraviolet spectroscope and a cured state is quantified in accordance with the change rate of absorbances obtained from a change of spectral characteristics by combining the spectral characteristic with a luminance value image and displayed. Thereby, decrease in defects due to irregular curing and uncured portion of the ultraviolet curable resin can be realized by measuring the temporal change of the cured state of the reaction curable resin as a screen image and optimizing an optimum curing condition of the ultraviolet curable resin.

    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.
