A cut resistant chemical handling glove that is flexible and lightweight comprises a cured, liquid-impervious polymeric latex shell. A tacky acrylic adhesive with low shear strength can be used. A cut resistant liner is slipped on the tacky adhesive coating and is infiltrated with a polymeric latex coating and cured to integrally attach the cut resistant liner with the cured polymeric coating. When the latex glove is worn on a hand and a cutting edge, such as a knife edge, contacts the glove, a crease is formed due to slip at the tacky adhesive-cut resistant liner interface creating a geometry that reduces cut stress intensity at the knife-edge thereby increasing the cut resistance of the glove. Processes for making and using these gloves are also described.

The invention provides a side-suction traumatic drainage sucker comprising a sucker and a flat drainage tube group, wherein a flat bulge is arranged at the upper surface of the sucker; a drainage channel is arranged at the side wall of the flat bulge; a groove is arranged at the lower surface of the sucker; a plurality of support pillars are arranged in the groove; the drainage channel is communicated with the groove; the periphery of the sucker is provided with a blank-holding outer edge; the flat drainage tube group is provided with at least two independent pipelines; and one end of the flat drainage tube group is inserted in the drainage channel. According to the invention, the flat bulge is arranged at the upper surface of the sucker; the drainage channel at the side wall of the flat bulge is used for connecting the flat drainage tube group; the height of the flat bulge protruding out of the sucker is lower so as to ensure that the flat bulge scrapping phenomenon can be effectively reduced; therefore, the phenomenon that the sucker falls off is reduced, the phenomenon that the side-suction traumatic drainage sucker falls off is reduced, a user can use the side-suction traumatic drainage sucker conveniently and the reliability of the side-suction traumatic drainage sucker is increased.

The invention discloses a storage battery insulating support plate. The storage battery insulating support plate is characterized in that: the overall structure is an insulating plastic whole which is formed by an isolation block, an insulating expansion working surface, an installation groove and a limit block; an upward part is the insulating expansion working surface; the front end of the insulating expansion working surface is the isolation block and the back end is the limit block; the back surface of the insulating expansion working surface is provided with the installation groove; the isolation block of one storage battery insulating support plate can be connected with the limit block of the other storage battery insulating support plate in a matching way. The area of the insulating expansion working surface is greater than that of the installation groove. The storage battery insulating support plate has the advantages that: the structure is simple, the storage battery insulating support plate is convenient to install and use, the insulativity is high, and the cost and the storage battery installation difficulties can be reduced obviously.

The invention discloses a forced moulting method for improving the production performance of meat breeding ducks, which solves the problems of high mortality rate, low fertilization rate and the like existing in the prior art. The method comprises the following steps: preparation before molt: eliminate unqualified breeding ducks, separate male and female; feeding period: stop feeding, take the initial body weight after 8 hours, calculate the weight loss rate by weighing every day on the 7th day and thereafter, supply water regularly, shorten Illumination time; Restoration feeding period: When the weight loss rate of male and female ducks reaches 15%, 28%-30% respectively, feed the finished feed, the amount of feed is different, water is supplied throughout the day, and the light is increased to 17h in the later period; mixed group: male-female ratio 1:4.6 ~4.8, time-limited feeding, change egg-laying feed after seeing eggs, feed freely when the egg-laying rate is above 20%, supply water throughout the day, and light for 17 hours; Immunization: Vaccines such as duck plague from the 2nd week to the 6th week after feeding. The invention is mainly used for the forced moulting of meat breeding ducks, so that the ducks can maintain a healthy physique, improve the quality of breeding eggs in the second laying period, and prolong the economic utilization period.

The invention provides a connection assembly of electric cores, which includes an end cover that can be fastened to one end of at least one electric core, the end of the electric core covered by the end cover has a positive pole lug and a negative pole lug, and the outer side of the end cap is provided with Two pole pieces, the pole pieces are connected with a bottom piece inside the end cap, and the bottom piece can be welded and fixed with the positive tab or the negative tab. The invention also provides a lithium battery including the connecting component and an assembly method. The advantage of the present invention is that: the bottom piece and the pole piece are connected together, which is convenient to fix with the tab of the battery cell, the pole piece and the bottom piece are directly fixed on the connection assembly, and the whole connection assembly can be directly operated during assembly without frequent Suction the pole piece and connection piece set separately, reduce the downtime of equipment caused by multiple pieces or missing pieces, and improve the utilization rate. When the pole piece is turned over, the tab has been fixed, and there will be no interpolation of the tab.
