The role of sizing wet separation and the problems in use
Overshot go into the heart of the drill pipe, the slider move up, make the tube socket head can be inserted into the center, when on the slider move up tight, using friction lift drill, remove loose again after the slider, by means of the connection string to slide along the block should tighten, set aside the center pipe, but in front of the salvage must first determine the bit in the bottom of the hole position, can be in a thin plate with bolts tight end of drill pipe, Drop the drill pipe to the bottom of the hole and press it on the drill bit. After waiting for a moment, it is proposed that the relative position of the drill bit at the bottom of the hole and the center of the rotary plate of the drill can be determined by observing the indentation left by the center pipe of the drill bit on the board, and then move the drill or rotary plate so that the center of the rotary plate is directly in front of the center pipe of the injured head, so as to ensure that the fishing device can be inserted into the center pipe accurately.
After the sizing machine , the wet splitting device, in addition to the G142-140 sizing machine designed and produced by China in the early 1960s, and the Beninger sizing machine imported from abroad after the reform and opening up, are not used. Almost all domestic sizing machines and imported sizing machines use a sizing machine and a wet splitting device.
The wet skeining device of the sizing machine is composed of a plurality of wet splitting rods, supporting legs and variable speed transmission mechanisms. It is installed between the slurry tank and the drying room. When the sizing is on the machine, a sizing value is placed between the warp beam and the shaft of the shaft by a sizing value. When the machine is turned on, the warp yarn is passed to the wet splitting device, and then the wet is manually The split rod is inserted, the sheet yarn is divided into several layers, and then the sizing is pre-baked in parallel into the drying room. Welcome to the company's official website http://
The production practice shows that the sizing wet-straining rod has a good " scraping " effect on the surface of the wet sizing yarn, so that the slurry is evenly spread on the surface of the yarn, so that the wet sizing yarn enters the drying room in parallel and is pre-flooded. The moisture of the yarn is quickly evaporated, the slurry film is quickly shaped and tends to be complete, the sizing hairiness is applied, the surface is smooth, the resistance of the dry splitting before drying is reduced, the integrity of the serosa is maintained, and the sizing is reduced. The regenerative hairiness, the reduction of the falling pulp, the improvement of the sizing quality and the integrity of the pulp shaft are very advantageous.
