The invention discloses an antistatic fabric preparation method, and relates to the technical field of textile material processing. The antistatic fabric preparation method specifically comprises thefollowing steps that S1, raw materials are selected; S2, a treatment fluid is blended; S3, antistatic soaking treatment is carried out on fibers; S4, a fabric is woven; and S5, the antistatic fabric is washed and dried. According to the antistatic fabric preparation method, the antistatic effect of the fabric can be enhanced in the aspect of materials by blending and weaving various antistatic conductive fibers, and the purpose that the antistatic treatment fluid can be fully adhered to the surface of each fiber is achieved by firstly performing antistatic soaking treatment on the non-conductive base fibers and then performing blending and weaving, the adhesive force of the treatment fluid is greatly enhanced by adding a thickening agent into the antistatic treatment fluid, the antistaticeffect of the antistatic fabric is greatly enhanced, and therefore large benefits to use of the antistatic fabric are achieved.

The invention relates to a technology that prepares a proton exchange membrane fuel cell electrode, comprising three parts of a pre-process of the proton exchange membrane, a preparation of a catalyst slurry and spray coating of a membrane electrode. The technology provided by the invention solves the problems that in prior art preparation process, the proton exchange membrane swells and rucks and the dosage of the catalyst is high and the preparation process is complicated. The prepared proton exchange resin has great elasticity and adhesive property, which is beneficial for improving adhesion of the catalyst layer and the proton exchange membrane and improves utilization ratio of the catalyst.

The invention discloses a full-automatic plane labeling machine in the technical field of plane labeling machines. The full-automatic plane labeling machine comprises a fixed support, the interior of the fixed support is in transmission connection with a conveying belt, the top of the conveying belt is connected with a plurality of groups of positioning mechanisms arrayed along the edge of the conveying belt, and the positioning mechanisms are used for positioning a labeling part. According to the full-automatic plane labeling machine, when labeling is carried out on a large labeling part every time, the front end and the rear end of a label are adhered and tensioned through a label pulling mechanism, the head of the label is prevented from wrinkling, the label is smoothly attached to the top of the labeling part advantageously, when the labeling part moves to a labeling position, the label pulling mechanism is slowly made to roll to be separated from the label, In cooperation with a limiting mechanism and a rotating mechanism, a leveling mechanism enables the label to be flatly attached to the top of the labeling part in the rightward conveying process of the label, and therefore it is guaranteed that the large label is flat in labeling process, and the phenomena of wrinkles and bubbles during labeling of the large label is avoided.

The invention relates to an asphalt recovery coating vibration reciprocating blender and an asphalt coating process thereof. At present, the domestic and foreign asphalt mixing plants used in the rapid development of domestic highways all adopt direct heating which causes the defects of easiness in stone surface carbonization and poor coating. The asphalt recovery coating vibration reciprocating blender comprises a reaction kettle, a heat transfer oil filling station and a vibrator, wherein automatic heat-proof doors are arranged on two sides of the reaction kettle respectively; a discharging bin with a cold stirred material discharging port and a hot stirred material discharging port is arranged on one side of the reaction kettle; a cold stirred material-hot stirred material separating plate is arranged in the discharging bin; the heat transfer oil filling station is connected with a heat transfer oil pipe on an inner wall of the reaction kettle; the vibrator is arranged in the reaction kettle; and a shock-absorbing device is arranged at the bottom of the reaction kettle. The invention provides a special heating manner for milling and planing materials, in which the temperature is controlled within 190 DEG C, the mining and planing material as well as asphalt is heated, and the mining and planing material rolls over in a bin under the action of reciprocating vibration, so as to ensure sound adhesion and form a pre-coated recovery material.

A medical fiber structure and a medical laminate are provided and herein are capable of sufficiently adhering to damaged tissue to stop bleeding and more reliably reinforcing weakened tissue by preventing air leakage or fluid leakage. The invention relates to the medical fiber structure including a fiber structure made of cellulose which is produced through etherification and carboxylation of hydroxy groups of cellulose.

The vibration stirring device capable of improving the distribution uniformityof the cement particles comprises a stock bin, a first vibration platform, a second vibration platform and a stirring mechanism, wherein a charge port is formed in the upper part of the stock bin, adischarge port with a valve is formed in the lower part of the stock bin, and shaft holes are formed in the two ends of the stock bin; the stirring mechanism comprises a stirring shaft, a stirring motor, a speed reducer, a first bearing seat and a second bearing seat; the two ends of the stirring shaft penetrate out of the corresponding shaft holes in a matching manner through elastic shaft seal,and are connected with one end of the first rotary shaft and one end of the second rotary shaft through a shaft coupling separately; the stirring motor, the speed reducer and the first bearing seat are arranged on a vibration surface of the first vibration platform; the stirring motor, the speed reducer and the other end of the first rotary shaft are sequentially connected; the first rotary shaftis supported on the first bearing seat in a matching manner; the second bearing seat is arranged on a vibration surface of the second vibration platform; and the other end of the second rotary shaft is supported on the second bearing seat in a matching manner. The device is capable of crushing cement balls and ash balls in a mixture through vibration, and uniformly distributing the cement balls and the ash balls into the mixture, and simple in structure.

The invention relates to the field of organic fertilizer production, in particular to a preparation method of a culture medium for organic fertilizer production. The preparation method comprises the following steps: step 1, preparing raw materials and preparation equipment; step 2, adding the raw materials and carrying out primary positioning on the adding amount of water; 3, mixing the raw materials, and allowing the raw materials to be attached onto eggs; 4, dispersing agglomerated raw materials; 5, positioning the adding amount of the water again; 6, putting oyster shells into a culture dish, and coating the oyster shells with the raw materials; and step 7, sterilizing the culture dish. When such a technical scheme is adopted, the culture speed of strains can be increased in the preparation process of the culture medium.

The invention relates to a method for manufacturing a hollow cylinder of pure quartz glass. The powder rod of the hollow glass cylinder is deposited by an external vapor deposition method. The deposition chamber adopts a vertical target rod deposition method, and the deposition target rod is high temperature resistant and oxidation resistant. Ceramics, alloys, or composite deposition targets with alloys as the base and covered with a ceramic layer. The surface of the deposition target maintains a certain roughness. The torch assembly is connected with a sliding seat that moves up and down. The disk drives the deposition target rod to rotate, turn on the blowtorch assembly to spray deposition powder to the deposition target rod and move up and down along the direction parallel to the deposition target rod axis, open the exhaust port, and the temperature difference of the heated area of ​​the entire deposition target rod is controlled at 350 °C Inside, after the deposition is completed and cooled, the target rod is extracted from the powder preform and sintered into a hollow cylinder of transparent pure silica quartz glass. The invention ensures the quality of deposition and molding of the powder rod, enhances the processing stability, simplifies the process and reduces the processing cost.
