The invention discloses a hydraulic internal mold device for a concrete box girder. The device comprises a mold board system and a plurality of oil cylinders; the mold board system comprises a top mold and multiple moving molds sequentially distributed on the left side and the right side of the mold board system, the mold boards are connected through hinges to form an inner cavity shape of the box girder in an enclosing mode, and the oil cylinders are longitudinally hinged between every two mold boards. A connecting rod mechanism is hinged between every two adjacent moving molds, the connecting rod mechanisms and the moving molds hinged to the connecting rod mechanisms together form a multi-rod mechanism, the oil cylinders and the connecting rod mechanism which are arranged between every two adjacent moving molds are hinged into a whole, piston rods of the oil cylinders stretch out to enable the internal mold system to keep the inner cavity shape of the box girder, and the piston rods contract to enable the internal mold system to be closed in a folded mode. Due to the fact that the connecting rod mechanisms and the moving molds are hinged and both can rotate around the joints, strokes of the oil cylinders can be greatly shortened through application of the connecting rod mechanisms; accordingly, the mold board system can be folded and contracted in an inner cavity of the box girder in a large angle, and then one-time integrated demolding of the overall internal mold device can be successfully achieved.

The invention relates to a cleaning agent for non-setting adhesive and belongs to the field of daily chemical products. The cleaning agent has the beneficial effects that progressively-induced feedingis carried out on locust larvae, parietal cells are stimulated to secrete gastric acid, and the secretion of digestive function enzyme of locusts to adhesive powder and the reproduction amount of corresponding intestinal microorganisms are enhanced, so that the decomposing capability of the non-setting adhesive can be greatly improved; by a composition with biological cleaning components, external components of the non-setting adhesive can be firstly decomposed to form gaps, and by matching with a wetting agent, the permeating effect of other components can be greatly improved and the cleaning effect can be achieved; since the starch octenyl succinate structure in a composite emulsifying component has hydrophobic alkenyl long chains and hydrophilic carboxyl groups, the cleaning agent system for the non-setting adhesive is not easy to form gel or flocculate, so that good free fluidity and hydrophobicity of a pressure-sensitive adhesive system in the preparation process are improved, particle agglomeration of other components such as composite fillers is prevented, and the dispersing effect and the permeating effect of pressure-sensitive adhesive are improved; the problems of poor permeation effect and low cleaning efficiency of the currently common non-setting adhesive are solved.

The invention relates to a polyester based on a polycondensation product of terephthalic acid and/or terephthalic acid derivatives comprising bivalent alcohols. Said polyester is characterised in that (I) between 40 and less than 90 mol. % of ethylene glycol, propane-1,3-diol and/or butane-1,4-diol is combined with (II) between 60 and more than 10 mol. % alkane-l,2-diol, exclusively ethylene glycol, and the polyester has a melting point of between approximately 145 and 250 DEG C (in accordance with DIN EN ISO 53765). It has a comparatively low melting point, such that it can be retreated at the lower melting temperature. This prevents undesired secondary and decomposition reactions during the retreatment, and enables energy costs to be reduced.; The inventive polyester is especially suitable for producing fibres or filaments by melt-spinning, and films, bottles and other moulded parts according to an injection moulding method. The fibres can be treated to form a high-quality nonwoven material.

The invention relates to a constipation-treating Chinese medicinal composition, wherein the composition comprises white atractylodes rhizome, dried rehmannia root, and cimicifuga rhizome.
