摘要： Disclosed is a nozzle block applied to an electrospinning device. At least one piercing unit (means of piercing) having a diameter smaller than the inner diameter of a spinning nozzle is coaxially disposed inside the spinning nozzle in order to prevent solidification of a solution at a tip of the spinning nozzle. The present disclosure includes a first cleaning mechanism for cleaning the spinning nozzle by reciprocating the piercing unit and the spinning nozzle relative to each other so that the tip of the spinning nozzle is unclogged, and a second cleaning mechanism for cleaning aggregates deposited around and outside the tip of the spinning nozzle through chemical cleaning and/or physical cleaning when the electrospinning process is temporarily stopped or after the electrospinning process is completed.

摘要： The present disclosure relates to a nozzle block applied to an electrospinning device, which includes a radiation nozzle having a hollow radiation needle for discharging a spinning solution to the outside; a means of piercing having a diameter smaller than that of the radiation needle, at least one of which is coaxially disposed inside the radiation needle; and a reciprocating mechanism for reciprocating the means of piercing and the radiation needle relative to each other, thereby preventing the solution from being solidified at the tip of the radiation nozzle or the radiation nozzle from being blocked by external contaminants even if the electrospinning process is temporarily interrupted in the middle.

摘要： Disclosed are a method of manufacturing a non-slip plate and a non-slip plate manufactured thereby. The method includes preparing a base metal plate for joint design, washing and surface treatment, preparing a non-slip material, adhering the non-slip material to the bonding surface of the base metal plate to form a protrusion, and brazing the base metal plate having the non-slip material adhered thereto in a brazing furnace. The non-slip plate is applied to vehicles to impart non-slip performance thereto, and can be semi-permanently used.
