The invention discloses a organic silicon compound containing silicon-silicon bond, silicon-carbon bond, silicon-halogen bond and ceramics precursor poly carbon silicon alky synthesized under high pressure and with medium in supercritical fluid status which uses mixture of the aforementioned compound as raw material, uses solvent soluble of poly carbon silicon alky as supercritical fluid medium. Ceramics precursor poly carbon silicon alky with different molecular weight and different softening point can be obtained by controlling reaction condition of synthesis. The inventive method effectively improves uniformity of heat transfer and reaction, with short reaction time, high synthesis efficiency, high synthesis yield. The produced poly carbon silicon has a high molecular weight, high content of bonds of silicon and hydrogen and uniform distribution of molecular weight. The inventive method can be widely used in preparation of SiC fibre, SiC composite, heat resistant alloy with high strength ...

The invention relates to an overloading movement rack roller guide and sliding plate overturning prevention method. The method is characterized in that the front portion and the rear portion of the two side faces of an overloading movement rack are provided with horizontal guide wheels, the front portion and the rear portion of the left bottom face and the right bottom face of the overloading movement rack are provided with vertical guide wheels, a further lower position of the rack is provided with an overturning prevention plate, and a tiny gap is formed between the overturning prevention plate and a sliding guide plate arranged on a base. When the rack moves, the horizontal guide wheels roll on a horizontal roller path of the base, and the vertical guide wheels roll on a vertical roller path of the base. The rack moves relaying on rolling of the guide wheels, the friction is small, and the rack can move forward and backward flexibly. When the rack bears forward-backward overturning moment ...
