The upper end of the round wall of a furnace body is connected with an expander by bricklaying through a refractory material, and the lower end of the round wall of the furnace body is fixed with a tray; the expander is movably connected with a support in a sliding manner; the lower end of a microporous ceramic tube is fixed with the tray while the upper end of the microporous ceramic tube is fixed with the support; the furnace body is fixed with a microwave generator and a shell; the shell is fixed with an upper flange and a lower flange; a gaseous magnesium collecting chamber is formed by the wall of the furnace body above the support, an upper convergent section of the shell and the inner side of the upper flange; a gaseous magnesium outlet tube is penetrated from the gaseous magnesium collecting chamber and then is fixed with the furnace body and the shell; a slag chamber is formed by the wall of the furnace body below the tray, a lower convergent section of the shell and the inner side of the lower flange; a magnesium ball is put in the microporous ceramic tube; slag is put in the slag chamber; the power of the microwave generator is 1-500KW, the frequency of the microwave generator is 300-3000MHz, the temperature of the microwave generator is 1200-1350 DEG C, and the smelting time is 15-60 minutes; the magnesium ball is acquired by roasting dolomite to acquire magnesium oxide and calcium oxide and then mixing silicon iron and fluorite with magnesium oxide and calcium oxide. The magnesium smelting technique by microwave heating is used for smelting magnesium, which is a microwave new energy heating technology.

The invention discloses a composition for preparing coating slurry and a preparation method of a fabric. Three compositions for preparing the coating slurry are prepared according to different coating modes; the reverse side of a cotton-containing base fabric is coated through three coating techniques including a roller, mould or plain net technique, a foam coating technique and a spray coating technique, wherein the vehicle speed is 15 to 30m/min; the application amount of the coating slurry is 25 to 35 percent of the weight of the fabric; baking is performed for 1.5 to 3.5min at the baking temperature of 150 to 170 DEG C; finally hydrophilic setting is performed by adopting a setting machine, wherein the vehicle speed of the setting machine is 15 to 20m/min, and the drying temperature for setting is 150 to 170 DEG C. By adopting the fabric prepared by the technique provided by the invention, a gradient water-retaining function of the fabric in the thickness direction is realized, a siphon-like effect can be realized through the water-retaining power difference, so that a persistent one-way moisture conducting function is formed, when a human body sweats, moisture on the fabric can realize gradient transfer from inside to outside, so that the fabric is ensured to have the functions of quickness in perspiration and comfort in wearing.

The invention provides a pressurizing device for construction based on constructional engineering and a using method thereof, and relates to the technical field of building construction. The pressurizing device solves the problems that when an existing pressurizing device for construction of constructional engineering is used, the connecting structure of a motor, a heat dissipation pipe and a pressurizing pump shell is complex, the motor is inconvenient to disassemble and maintain, meanwhile, a connecting ring in a coupler is extruded for a long time, so that an elastic support is loosened, the elasticity is reduced, an impeller shaft rod is deflected and damaged, and in the concrete pressurizing process, air is easily sucked in, the conveying flow is unstable, and the working efficiency is influenced. The pressurizing device comprises a bottom plate, wherein the left side of the top end of the bottom plate is provided with an air pressure tank, and the right side is provided with two booster pump shells. According to the pressurizing device, due to the fact that an elastic support is pressed and fixed between a top half coupling and a bottom half coupling, through the elastic effect of a compression spring and the structural characteristics of the elastic support, the elastic support is effectively prevented from being loosened to cause elasticity reduction, and it is guaranteed that the using effect is long and reliable.
