The invention discloses an expansion anti-crack waterproof agent, which comprises the following raw materials in mass percentage: 5-30% of anti-crack expansion agent, 20-40% of microbeads, 25-45% of coal gangue, 0.1-8% of modified basalt fiber, Admixture 1‑5%. In the present invention, the anti-crack expansion agent and the modified basalt fiber can play a superimposed and compensatory shrinkage effect in the concrete, and have double anti-crack and waterproof functions; the modified basalt fiber makes it better combined with the concrete, without affecting the concrete On the basis of construction performance, the structural density of concrete is increased.

The invention discloses a flexible self-expanding gas drainage drilling and sealing device and method, which are suitable for underground use in coal mines. Two sections of flexible plugs at the front and rear are fixed at the fixed groove on the gas drainage pipe, and a pre-mixing pipe with a one-way valve is embedded in the two plugs respectively, and the one-way valve at the entrance of the pre-mixing pipe is connected to three When drilling and sealing the holes, connect the material bags containing the two components of A and B to the tee, squeeze the material bags to make the two-component materials automatically mix during the process of flowing through the premixing tube Evenly and then enter the flexible plug, after the predetermined amount of two-component material is injected into the front and rear flexible plugs, quickly send the gas drainage pipe together with the flexible plug to the predetermined position in the borehole, and wait for the expansion and solidification , forming a grouted airtight space. The device is simple in structure, light in weight and small in size, and can complete gas drainage and sealing holes without carrying a high-pressure pump or a water tank during use, and has wide practicability.

The invention relates to an OLAP pre-computing model, an automatic modeling method and an automatic modeling system. The model includes: a dimension module, an aggregation group module, and a measurement module; the method includes: performing data statistics on all data sources to obtain data statistics Result; determine the business model according to the data model given by the user and perform query rehearsal on the target query; perform query rehearsal on the sample and collect query statistics; perform physical modeling and define dimensions, measures, and aggregation groups of the pre-computing model ; get the business modeling result; get the pre-calculation model; the system includes: data statistics module, business model module, query statistics module, modeling building module. The present invention combines pre-computing dimensions more effectively by adding derived dimensions and aggregation groups, reduces redundant calculations and data storage, and has higher computing efficiency and smaller storage occupation, thereby achieving better effect.

The invention provides low-temperature-hot-stamped gold-stamped type tipping paper for cigarettes and a preparation method of the tipping paper. The low-temperature-hot-stamped gold-stamped type tipping paper for the cigarettes and the preparation method of the tipping paper are used for overcoming the disadvantages in existing high-temperature hot-stamping that the energy consumption is high, and that the rate of finished products is low and the cold hot-stamping effect is poor. The gold-stamped type tipping paper for the cigarettes, provided by the invention, is prepared through firstly printing environment-friendly alcohol-soluble white ink and printing ink on a base paper layer, then, additionally printing a layer of an adhesion-assisting glue material on the environment-friendly alcohol-soluble ink layer, then, carrying out low-temperature hot-stamping at the temperature of 85-100 DEG C, and carrying out laser boring, slitting and rewinding. According to the low-temperature-hot-stamped gold-stamped type tipping paper for the cigarettes, provided by the invention, an adhesion-assisting layer is additionally printed on the ink layer and has the functions of protecting the ink layer, enhancing the hydrophobicity of the ink layer and improving the adherence with a gold-stamped layer and the fastness of adhering of winding-adhesive glue, and special electrochemical aluminum hot-stamping foil for low-temperature hot-stamping is used in a matched manner, so that a low-temperature hot-stamping procedure can be completed at the temperature of 85-100 DEG C, and the energy consumption of a gold-stamping process is greatly lowered, and the service efficiency of a gold-stamping plate is increased, and thus the cost of gold-stamping is reduced.
