The invention relates to a molten steel slag centrifugal granulation treatment and waste heat recovery system which is characterized in that a slag inlet is formed in the top of a centrifugal granulation bin, a rotating disc and a rotation driving motor are arranged in the centrifugal granulation bin, the rotating disc is arranged below the slag inlet, and the rotating disc is driven by the rotation driving motor; the low-melting-point eutectic metal self-flowing bed waste heat boiler is arranged below the centrifugal granulation bin, a self-flowing bed waste heat boiler heat exchange pipe is arranged in the low-melting-point eutectic metal self-flowing bed waste heat boiler, and low-melting-point eutectic metal is loaded in the self-flowing bed waste heat boiler heat exchange pipe. High-grade waste heat recovery of the high-temperature molten steel slag is achieved, the blank of heat energy recovery of a steel mill is filled up, and energy conservation, emission reduction and carbon reduction of the steel mill are greatly promoted. The two links of centrifugal granulation treatment and waste heat recovery are comprehensively and integrally designed, the structure is simpler and more compact, the efficiency is higher, operation is easy and convenient, the production implementation process is safe, and the device can be applied and popularized in ferrous metallurgy enterprises.

This invention discloses a pneumatically protected electric chuck structure, comprising a fixed end and a rotating unit. The rotating unit includes a rotating base, an inner ring chamber, and an outer disk. The inner ring chamber is fixed to the rotating base and the outer disk on both sides, respectively. An electric power source assembly is installed in the fixed end, driving the rotating base to rotate on one side of the fixed end. A pneumatic control mechanism is fixed in the fixed end. An actuator is slidably installed in the inner ring chamber, comprising an actuator body and three sets of sliding blocks. The pneumatic control mechanism drives the actuator body to move laterally within the inner ring chamber. The actuator body, through the three sets of sliding blocks, drives three sets of jaw arms to move centered on the front side of the outer disk to clamp materials. This invention effectively utilizes pneumatic protection to improve the safety of electric chuck operation, significantly increases the upper limit of electric chuck rotation speed, and assists in achieving pneumatic emergency stop, effectively protecting the use of the electric power source.

According to the lining adding device, lining cloth is conveyed more smoothly, and the conveying efficiency of the lining cloth is improved.

The invention relates to the technical field of coatings, in particular to bio-based water-based toy paint applied to a degradable base material and a preparation method of the bio-based water-based toy paint. The water-based toy paint comprises varnish, wherein the varnish comprises the following components in percentage by mass: 60-80% of a film-forming main agent, 3-5% of a film-forming auxiliary agent, 0.2-0.5% of a wetting agent, 0.1-0.2% of a defoaming agent, 2-5% of wax emulsion, 0.5-2% of matting powder, 0.1-0.2% of a flatting agent, 0.5-1% of a thickening agent and the balance of purified water. The adhesive force on the surface of a degradable base material is excellent, the market vacancy of products of the same type is filled, and the industrial pain point is further solved.

The invention belongs to the technical field of release materials, and relates to a release film for a flexible ultrathin glass protective film and a preparation method of the release film. The release film comprises a base film and a release layer arranged on any surface of the base film. A coating liquid of the release layer is prepared from the following components in parts by weight: 10 to 30 parts of water-based hydroxy acrylic resin A; 5-20 parts of a water-based modified acrylic polymer B and 0.5-5 parts of a cross-linking agent; 0.5-5 parts of a wetting agent; and 40-84 parts of deionized water. In the preparation process of the flexible ultra-thin glass (UTG) protective film, the flexible ultra-thin glass protective film has moderate adhesiveness and peelability to a bonding body, and pollution to elements such as silicon and fluorine of a contact layer is effectively avoided. Therefore, the method can be widely applied to manufacturing of flexible ultra-thin glass (UTG) protective films.
