The invention discloses a formula of a flexible graphite impregnating agent and a preparation and application process thereof. The impregnating agent is a glue liquid formed by adding expandable graphite with different particle sizes and different concentrations into water in which a treatment agent is dissolved. The impregnating agent is immersed into the anode pores by means of negative pressure first, then positive pressure and ultrasonic waves, and flexible graphite of different particle sizes can effectively fill the pores of the corresponding particle size. After several times of gradient heating, the expansion effect of each heating has different effects. Different pores and pore channels are filled and blocked with different effects, which not only increases the density and weight of the anode carbon block, but also because the main component of the impregnant is treatment The latter flexible graphite can be closely combined with the inside of the carbon block to prevent slag drop, improve the current density, and fill the pores to block the oxidation reaction channel, which reduces the ineffective oxidation and prolongs the service life.

The invention provides a bicycle frame which comprises a first frame body, a second frame body and a plurality of rib plates. The rib plates are arranged between the first frame body and the second frame body and used for enlarging the bearing force of the first frame body and the second frame body. The first frame body, the second frame body and the rib plates are integrally formed through extrusion molding. A central shaft installation part is arranged on the second frame body. The invention further provides a method for manufacturing the bicycle frame. The method includes the steps of material preparing, die heating, ingot casting heating, extruding, dragging, straightening and saw cutting. In addition, the method provides a bicycle comprising the bicycle frame.

The present invention discloses a method for removing tangerine peel by adopting biological enzyme method. Said method includes the following steps: (1), using needle bed to prick cleaned tangerine; (2), adding pectinase whose mass concentration is 1.5-5% and cellulose whose mass concentration is 1-5% into water and uniformly stirring them so as to obtain an enzymolysis solution; (3), soaking thepricked tangerine in the prepared enzymolysis solution, then evacuating, after the enzymolysis solution is penetrated into the tangerine interior, restoring to normal pressure; (4), heating to 30deg.C-60deg.C, retaining for 0.25-2.5h to making enzyme treatment; and (5), using external force to remove peel and remove pith so as to obtain the invented peeled tangerine.

The invention relates to a preparation method of an aptamer affinity column having the advantages of simple operation, fast coupling speed and high coupling efficiency, and the aptamer affinity column is prepared from NHS activated sephrose4FF as a carrier and ochratoxin A specific aptamer as a ligand. After systematical review, the affinity column has good applicability in traditional Chinese medicines, and can achieve the purpose of rapid purification of the ochratoxin A in the traditional Chinese medicines, the established detection method is good in accurate degree and high in sensitivity, and can be used for rapid screening of the ochratoxin A in the traditional Chinese medicines. In addition, the preparation method of the aptamer affinity column is simple, easy, low in production cost, and stable and controllable in quality, can meet the rapid detection of the ochratoxin A in the traditional Chinese medicines, and has broad development prospects.

The invention relates to a construction device for long-distance and large-diameter cable laying in a cable trough, including a walking lifting device. The walking lifting device is provided with a lifting frame, and a flexible bottom bearing is detachably installed on the lifting frame. bracket. The invention also discloses a long-distance and large-diameter cable laying construction method in the cable trench. The invention has the following beneficial effects: firstly, a cable trench is drilled on the ground with a ditching tool, and cables are laid on the side of the cable trench along the length direction of the cable trench. It is easier to lay the cables on the side of the cable trench Realize mechanized operation, and then transfer the cables to the cable trench through the long-distance and large-diameter cable laying construction device in the above-mentioned cable trench, and then backfill the cable trench with soil, which reduces the required labor force and greatly reduces the labor intensity. The safety is improved, the operation method is simple and easy to implement, easy to popularize, and can generate greater economic benefits.

The invention provides a hydraulic forming and quenching device for plate springs, and the hydraulic forming and quenching device comprises a support pillar, a disc, an annular oil groove, a center valve, a forming fixture, a supporting roller, a driving and braking hydraulic oil cylinder, a plunger pump motor set, and a PLC (programmable logic controller)-based control system, wherein the forming fixture is provided with a fixture oil cylinder, and the control system comprises an induction plate and a proximity switch. The length of a stokehold rotating conveying chain required by the device disclosed by the invention is just 5 meters, and the forming fixture is annularly arranged, so that the hydraulic forming and quenching device for the plate springs disclosed by the invention is small in land-occupied area and small in application amount of a quenching medium, therefore, the hydraulic forming and quenching device for the plate springs is low in cost for putting into operation and high in production efficiency, the positions of operators are fixed, and the implementation of mechanized operation is facilitated.

The invention provides a honeycomb-structured building block wall body and belongs to the field of construction materials and construction engineering. A wall body main body is formed through connecting hexagonal building blocks 5; two vertical edges of the wall body are formed through connecting pentagonal building blocks 2; the middle part of the wall body is a pouring band 7; a bottom edge of the wall body is composed of a self-leveling cushion layer 13; an upper edge of the wall body is a foam plate 10 or an anti-corrosion wooden wedge 24; rabbets 16 are arranged at three edges of an upper half part of each hexagonal building block 5 and mortises 17 are arranged at three edges of a lower half part of each hexagonal building block 5; the rabbets 16 are arranged at a horizontal edge and an adjacent upper inclined edge above each pentagonal building block 2; the mortises 17 are arranged at a horizontal edge and an adjacent lower inclined edge of the lower end; the mortises 17 are arranged at vertical edges which are connected with the horizontal edge on the upper side and the horizontal edge at the lower end; and the rabbets 16 and the mortises 17 between the adjacent building blocks are buckled together and a cast-in-place seam 20 is formed. The honeycomb-structured building block wall body is simple in structure and convenient to construct; a previous wall body can be stably connected in secondary decoration and the building blocks are not cut in a construction process; and the building blocks are finely positioned and mechanical work is easy to realize.
