This invention belongs to the technical field of mine support materials and preparation processes, specifically involving a composite inorganic sprayed slurry made from gasified slag and a preparation process for low-resilience, high-strength mine support. The sprayed slurry is a pure inorganic component, composed of activated gasified slag, ordinary silicate cement, auxiliary cementitious admixtures, and functional additives in specific mass proportions. The activated gasified slag undergoes alkali activation or thermal activation treatment, without using saline wastewater. The preparation process includes gasified slag pretreatment and activation, dry powder premixing, slurry preparation, high-pressure spraying support, and natural curing. This invention achieves high-volume utilization of gasified slag, solving problems such as saline wastewater activation, the presence of organic components in the sprayed slurry, and insufficient resilience and strength in existing technologies. It is suitable for various types of mine roadway support.

The invention relates to a low-nitrogen pulverized coal burner suitable for ultra-low load and a burning method, and belongs to the technical field of pulverized coal furnace burning. The pulverized coal burner is provided with a pulverized coal channel and a rich-lean separation device, the rich-lean separation device is composed of multiple stages of separation baffles, and all the stages of separation baffles are sequentially arranged in the axial direction of the pulverized coal channel. The pulverized coal channel is divided into a first-stage concentrated phase channel and a first-stage light phase channel through a first-stage separation baffle; the first-stage concentrated phase channel is divided into a second-stage concentrated phase channel and a second-stage light phase channel through a second-stage separation baffle; the (n-1) th-stage concentrated phase channel is divided into an n-stage concentrated phase channel and an n-stage light phase channel through an n-stage separation baffle; and a hydrogen swirl nozzle and an igniter are arranged in the n-stage concentrated phase channel. The method can be applied to the scene of deep peak regulation of the coal-fired boiler, the problem of heat efficiency reduction caused by ultralow-load operation is comprehensively considered and solved, and safe, efficient and environment-friendly operation of the pulverized coal boiler under the ultralow-load working condition is achieved.

The invention discloses an automatic batching method based on multi-bin solid waste materials and related equipment, and relates to the field of iron and steel industry. The method comprises the following steps: firstly, setting a target range of one or more key material components, and obtaining the component content and the initial mass feeding rate of the current associated solid waste material of each bin; then, for each material component with the set target range, according to the initial set amount corresponding to each solid waste bin and the component content of the material component in each solid waste bin, calculating a weighted average value corresponding to the material component; and if any weighted average deviates from the corresponding target range, automatically triggering the ratio optimization model to solve, and dynamically adjusting the feeding rate of each bin. According to the method, a traditional extensive mode depending on artificial experience or fixed proportioning is abandoned, and the proportioning precision and the component stability are remarkably improved.

The invention discloses an oxygen barrier coating, a preparation method thereof, a packaging material and a package, and belongs to the technical field of food packaging. The preparation method of the oxygen barrier coating comprises the steps that multiple layers of coating are carried out on the surface of a base material at the same time, drying is carried out while coating is carried out, the oxygen barrier component in coating slurry used for coating each layer is PVA, and the number of coating layers is at least two. The preparation method is easy, convenient and environment-friendly to operate, multi-layer coating and drying are carried out on the surface of the base material at the same time by adopting the coating slurry with PVA as an oxygen barrier component, on one hand, the coating can have good uniformity, and on the other hand, the coating can have high binding force. In addition, compared with an existing EVOH co-extrusion mode, the PVA coating mode has the advantages that the cost is reduced, and meanwhile, the oxygen resistance and the tensile resistance of the coating are improved.
