The invention belongs to the technical field of car air-conditioning gluing, and specifically relates to a car air-conditioning automatic gluing production line. The production line comprises a loading and unloading station, a workpiece detection unit, a plasma surface processing unit, a visual unit, a gluing unit, a drying unit, a cooling unit and a transmission mechanism. The loading and unloading station places a workpiece on a workpiece tray, then the workpiece tray is transported to the workpiece detection unit by the transmission mechanism through a conveying belt, the workpiece detection unit detects the placement stability of the workpiece, after the detection the workpiece is transported to the plasma surface processing unit, the plasma surface processing unit carries out surface processing on the workpiece, after the surface processing the workpiece is orderly transported to the visual unit and the gluing unit, the gluing unit carries out gluing on the workpiece, after the gluing process the workpiece is orderly transported to the drying unit and the cooling unit, and finally the workpiece is unloaded from the loading and unloading station. The production line can achieve the continuous automatic production of glued workpiece, and the production efficiency is improved on the basis that the production qualification rate is guaranteed.

The embodiment of the invention discloses a continuous and automatic production line of a polyurethane adhesive and aims to solve the problem that since the materials are in contact with air, crust is generated and influence is caused on the product quality in the intermittent production process of the existing polyurethane adhesive. The continuous and automatic production line of the polyurethane adhesive comprises a calcium powder bale breaker, a calcium powder drying tank, a calcium powder cooling storehouse and a calcium powder measuring tank which are successively connected with one another via a pipeline; a carbon black powder bale breaker, a carbon black powder drying tank, a carbon black powder cooling storehouse and a carbon black powder measuring tank are successively connected with one another via the pipeline; a side feeder, a pre-mixing screw machine, a first-stage screw machine, a high-viscosity material cooler, a second-stage screw machine, a material pressing machine, a filter and a split charging device are connected with one another via the pipeline; the outlets of a prepolymer measuring tank, the calcium powder measuring tank and the carbon black powder measuring tank are communicated with the inlet of the side feeder via the pipeline; the outlet of a catalyst measuring tank is communicated with the inlet of the second-stage screw machine via the pipeline.

The invention provides a light-weight casting material. The light-weight casting material is prepared by mixing raw materials including 10 to 50 percent of rod-shaped aggregate, 0 to 45 percent of light-weight aggregate, 4 to 10 percent of silicon ash with the granularity less than or equal to 0.2mu m, 17 to 30 percent of bauxite cement, 8 to 20 percent of floating microspheres, 5 to 10 percent ofclosed-pore pearlite, 0 to 10 percent of high alumina bauxite powder and a water reducing agent. According to the light-weight casting material provided by the invention, the small-size rod-shaped aggregate is uniformly dispersed so that the firing after-shrinkage of a product is reduced, the thermal shock resistance of the casting material is remarkably improved and the service life is greatly prolonged; different amounts of the light-weight aggregate which is continuously graded are added, so that the casting material has high strength and good flowability and casting materials with different thermal conductivity coefficients can be prepared, and furthermore, an application range of the casting material is expanded.

The invention discloses a method and an apparatus for continuous conversion production of sodium nitrate, and belongs to the technical field of production of inorganic chemical engineering products. The method mainly comprises the processes of mother liquor pre-conversion, conversion absorption and tail gas separation. The system of the apparatus mainly comprises a conversion absorption tower, a converter, an absorption separator, a matching pump and a matching pipeline, and the conversion absorption tower is a packed tower, and comprises an upper portion pre-conversion segment, a middle portion conversion absorption segment and a lower portion solution storage tank; and a conversion solution obtained after pre-conversion and conversion reactions of a mixed mother liquor and a circulating solution enters the solution storage tank, parts of the conversion solution returns to the conversion absorption tower through a conversion circulating pump, the remaining conversion solution is pumped into the converter in order to produce solid sodium nitrate, and generated tail gas is sent to a 4# alkali absorption tower, and is absorbed to produce sodium nitrite. The method and the apparatus optimize technological operation, improve the sodium nitrite conversion rate and the qualified rate of sodium nitrate, enlarge the productivity, reduce the production cost, realize continuous and automatic production of sodium nitrate and are in favor of realizing energy saving and emission reduction.
