    Abstract: Provided is a method of preparing a powdery diacetal clarifying agent, which comprises mixing an aromatic aldehyde, a polyol, and an acid catalyst in an organic polar solvent, adding a hydrogenating agent and an inorganic silicon-containing agent into the foregoing mixture, and filtering the mixture. The powdery diacetal clarifying agent prepared by the method can have excellent flowability, dispersability, thermal resistance, and color stability. Accordingly, the powdery diacetal clarifying agent does not release stinking odor and incur yellowing at high temperature, allowing the plastic articles to have improved appearance and visual appeal.

    Abstract: Disclosed is a microwave-transmitting mould structure, comprising a first template, a second template and a mould combining unit. The mould combining unit has a first snap fit, a second snap fit and an engagement member. The first snap fit is arranged on the first template; the second snap fit is arranged on the second template; and the engagement member is snap-fit engaged between the first snap fit and the second snap fit, so that when the first template and the second template are subjected to an outward pressure, corresponding faces thereof which the engagement member can pass through respectively abut against abutting faces of the first snap fit and of the second snap fit, and thus, the first template and the second template cannot be separated from each other due to an increased pressure inside the mould.
