2) flammable cracking, in which when the temperature reaches the ignition point or meets other fire sources, the fire is ignited and heat is released; and finishing the mixing of the tobacco.
3) The heat released causes the fibers to continue to crack and burn, causing the flame to spread.
The flame retardant principle of the existing flame retardant fabric is divided into two principles, one is to accelerate dehydration and carbonization of fibers to reduce combustible substances so as to achieve flame retardance, for example, ammonia treatment of the fabric and treatment of cotton cloth; the other is to change the internal structure of the fiber through a chemical process, reduce combustible components and achieve the purpose of flame retardance.

As shown in fig. 1-4, a device for preparing a flame-retardant fiber fabric comprises a charging basket 1, a barrel cover 2 and a stirring component 3; a barrel cover 2 matched with the charging barrel 1 is arranged at the barrel opening of the charging barrel 1; 2 departments of bung are equipped with stirring subassembly 3, stirring subassembly 3 is to 2 crossing insertions of bung, and stir subassembly 3 and bung 2 are the cross arrangement after inserting, stirring subassembly 3 includes screw thread plug bush 34, screw thread plug bush 34 and 2 cross insertions of bung, insert axostylus axostyle 32 in the screw thread plug bush 34, axostylus axostyle 32 is two-way overhanging than screw thread plug bush 34, axostylus axostyle 32 end connection outwards has a head 31, end connection towards the storage bucket 1 inboard has dash and blows piece 35, one side of screw thread plug bush 34 dorsad storage bucket 1 is equipped with spring 33, 32 departments are located to spring 33 cover, and spring 33 both ends are respectively with head 31 and screw thread plug bush 34 looks fixed connection.
Wherein, the flushing and blowing piece 35 comprises a sleeve 355, the sleeve 355 is arranged in the charging basket 1, a flushing plug 353 matched with the pipe cavity of the sleeve 355 is arranged at the inner side of the sleeve 355, and the flushing plug 353 is connected with the shaft 32 and is used for inserting the shaft 32 into the sleeve 355 and sliding with the sleeve 355; a return spring 352 is further arranged in the plunger 353, the bottom of the return spring 352 is connected with a sealing cover 351, the sealing cover 351 is connected with a sleeve 355 in a threaded mode and used for adjusting the relative position of the return spring 352 to the plunger 353, and spray holes 354 are uniformly arranged on the side wall of the sleeve 355.
In this embodiment, traditional mechanical stirring, because of the drive assembly noise magnitude of sound that adopts is big, the way, based on stirring subassembly 3 moves in storage bucket 1, stirs the processing to the powder, wherein stirs the processing and divide into two processes:
the handle 31 is pulled, and the impact blow piece 35 moves like a bullet in the charging basket 1 due to the elastic force accumulated by the spring 33 in the stretched state, and contacts with the powder, thereby achieving the purpose of mixing and stirring.
In addition, the shaft 32 is rapidly fired, compressing against the sleeve 355, i.e., compressing air through the plunger 353 into the sleeve 355, to further mix the powder as it is ejected through the orifice 354.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, which fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
