The invention discloses a waterproof concrete synergist and a preparation method thereof, and relates to the technical field of concrete admixtures. The waterproof concrete synergist comprises the following components by mass: 12-16% of polyaminated cellulose microspheres, 17-32% of modified waterborne polyurethane, 7-10% of a dispersant, 4-7% of a retarder, 2-5% of polyaluminum ferric sulfate, and the balance of water. According to the synergist, cement can be more sufficiently dispersed in concrete, so that the early strength and the later strength of the concrete are improved; and in addition, the synergist has the waterproof capability, and the practical engineering application range of the agent is expanded due to the improvement of the waterproof capability.

The invention discloses a slump retaining type concrete synergist and a preparation method thereof. The concrete synergist is prepared from the following substances in parts by weight: 12-20 parts ofa reinforcing agent, 8-15 parts of a regulator, 5-10 parts of an alkanol acrylate copolymer, 3-8 parts of maleic anhydride, 4-8 parts of a retarder, 2-5 parts of a lubricant and the balance of water.According to the invention, the polyol can make the cement fully hydrated; after the active sodium salt is doped into the concrete to promote the generation of low-sulfur calcium sulphoaluminate and hexagonal plate solid solution, the hexagonal plate solid solution fills internal pores and capillary channels of the concrete, so that the compactness of the concrete is improved, and the strength ofthe concrete is promoted to be improved. The alkanol acrylate copolymer can control the slump loss of concrete over time, so that the [xi] potential of the surface layer of cement particles is kept unchanged, and the cement particles are uniformly dispersed. Under the synergistic effect of the components, the synergist can obviously improve the early strength and later strength of concrete.

The invention discloses an environment-friendly mildew-proof agent. The environment-friendly mildew-proof agent comprises the main materials by weight: quaternary ammonium salt derivative, casson, phenol, pentachlorophenol, organic mercuric salt, organic tin salt, inorganic-salt copper sulfate, mercuric chloride and sodium fluoride. The environment-friendly mildew-proof agent also comprises the auxiliary materials by weight: surface active agent, synergist, propionic acid and anhydrous calcium chloride. The invention relates to the field of mildew-proof technologies of objects. The environment-friendly mildew-proof agent disclosed by the invention has the beneficial effects that the condition that the mildew-proof agent sold on the market contains certain chemical components polluting the environment so as to be not environment-friendly is solved, the toxic components polluting air is better reduced, the odor is thoroughly reduced, the larger pollution caused to surrounding air is avoided, and the concept of green and environment-friendly development is conformed; and the environment-friendly mildew-proof agent is more stable for oxidizing and reducing agents, is uniform in dispersion, stable in heat and wide in PH range, can be used in the range of 2.0-12.0, and is low in use amount, difficult in combustion, easy in transportation and convenient in use.

The invention discloses tea packaging can forming and processing equipment. The tea packaging can forming and processing equipment comprises a workbench, wherein two groups of supporting rods and a yielding groove are arranged at the upper part of the workbench; a cover plate is fixedly mounted at one ends of the two groups of supporting rods; a hydraulic cylinder is fixedly mounted at the lower part of the cover plate; two groups of right-angle plates are fixedly mounted at one end of the hydraulic cylinder; a motor is fixedly mounted at one ends of the two groups of right-angle plates; a drilling cylinder is fixedly mounted at the output end of the motor; a discharging circular plate is mounted in the drilling cylinder in a sliding manner; two groups of semicircular transparent pipes are mounted on the side of the drilling cylinder; a treading mounting plate is mounted below the workbench; and a power socket is mounted on the side wall of the workbench. The tea packaging can forming and processing equipment has the beneficial effects that through the discharging circular plate, an operator does not need to manually take out wood in the drilling cylinder, so that the working steps of the tea packaging can forming and processing equipment are reduced, and the working efficiency of the tea packaging can forming and processing equipment is improved.

The invention belongs to the technical field of textile printing and dyeing, and particularly relates to a short-flow processing technology for a dope-dyed fabric. The method comprises the following steps: singeing, desizing and tentering a dope-dyed fabric to obtain a dope-dyed fabric; a feed liquid used in the pretreatment desizing procedure is prepared from 6-8 g/l of desizing enzyme OPT-280, 1-5 g/l of chelating agent and 6-8 g/l of penetrant. And a feed liquid used in the after-finishing tentering process is formed by mixing a modified polysiloxane softening agent TF-4865C and a polyethylene polyamine color fixing agent GD-80. The fabric is soft in hand feeling and excellent in color fastness, the invention further provides a processing technology of the fabric, processing, desizing, scouring and dyeing are not needed in the dyeing and finishing process, the fabric is diversified in color and bright in finishing mode, the technological process is short, discharge of printing and dyeing wastewater is greatly reduced, and the fabric conforms to the green and environment-friendly development concept at the present stage.

The invention discloses a full-automatic filling machine for outer wall surface water-based paint. The full-automatic filling machine for the outer wall surface water-based paint comprises a containing base, and an automatic discharging pipe is fixedly installed on the inner bottom face of the containing base in a penetrating mode. The full-automatic filling machine for the outer wall surface water-based paint has the beneficial effects that through the automatic discharging pipe, when the outer wall surface water-based paint needs to be filled, the side wall of a containing barrel can abut against a transverse moving rod to move, when the interior of a limiting ring and a sealing circular plate are staggered, the outer wall surface water-based paint falls into the containing barrel through a gap between the sealing circular plate and an intercepting hole plate, as the outer wall surface water-based paint is guided into the containing barrel, the containing barrel abuts against a recycling plate and vertically moves downwards, when the downward moving height of the containing barrel exceeds the length of a transverse moving rod, multiple sets of telescopic springs abut against a sleeving pipe, the sealing circular plate and the transverse moving rod are made to return to the original positions, and at the moment, the limiting ring is sealed; and through the arranged automatic discharging pipe, an infrared position sensor, a liquid level sensor and a plurality of sets of power equipment do not need to be installed, and the paint can be automatically guided into the containing barrel.

The invention discloses a mold for metal casting molding. The mold comprises a lower mold plate and an upper mold plate, wherein two sets of alignment grooves, a stamping groove and two sets of guide rods are arranged at the upper part of the lower mold plate; a limiting frame is fixedly installed in the stamping groove; damping springs sleeve the side walls of the two sets of guide rods; two guide pipes and two sets of connecting rods are arranged at the upper part of the upper mold plate; a stamping head and two sets of abutting plates are fixedly installed at the lower part of the upper mold plate; a plurality of blowing air pipes are installed in the upper mold plate; alignment steel cables are installed above the two sets of guide rods; and replacement clamping plates are installed at the front part and the rear part of the upper mold plate. The mold has the beneficial effects that cleaning work of the stamping head can be automatically completed through the blowing air pipes without an electric power structure, so that consumption of electric power resources is reduced, meanwhile, the production and installation cost is reduced, and the mold for metal casting molding conforms to the concept of green and environment-friendly development.
