Description
Technical field
Field of chemical fiber production equipment of the present invention, relates to a kind of dry heat draw box, is specifically related to a kind of temperature high uniformity
Dry heat draw box.
Background technology
Owing to superhigh molecular weight polyethylene fibers has high intensity, high-modulus, low-density feature, therefore it is fine with carbon
Dimension, aramid fiber also claim the world today three big tec fiber.Owing to its molecular weight is high, main chain is combined, the degree of orientation, degree of crystallinity
Height, therefore its intensity be current all fibres, (under the conditions of equivalent weight, be equivalent to the 8 of high-quality steel wire with its intensity height
Times), modulus high (1300g/d), advanced lightweight composite demonstrates great advantage, is widely used in national defence military supplies
Equipment, such as bullet-proof vest, the helmet and lightweight armor, and the aspect such as civilian sail, hawser, parachute and filter material.
High-tenacity polyethylene fibre many employings gel spinning-super times heat stretching process produces at present, through the fiber of spinning moulding,
It is referred to as as-spun fibre.Owing to its structure is the most unstable, supermolecule structure order is relatively low, so its Physical Mechanical can meet
Textile process requirement, it is necessary to by a series of post-treatment operations, most important of which is exactly drafting process.After drawing-off is processed
After fiber obtains corresponding rock-steady structure, just can meet the requirement of textile process, and have good stability in use, in stretching
During the macromolecular chain of fiber or aggregated structure unit unfold, and along the axial oriented of fiber, same in orientation
Time, along with the change of phase, and the change of other architectural features.
A length of 2.5 meters～6 meters of general draw box, use casing self-circulation mode, and hot blast one enters one and goes out, internal
There is thermostat.There is hot blast circulation form two-way, unidirectional.Temperature in general hot tank is inconsistent, uneven, but have one bright
Aobvious thermograde fall.And this gradient fall, constant temperature heating device also is difficult to balance-its heat make-up, more forms air outlet
Hot blast temperature is high, the phenomenon that air inlet (circulating fan) temperature is low, because cold air enters in hot tank, can take away part heat
Amount, causes at the air outlet that temperature is higher, and the stretching, extension of fiber is maximum, and plastic deformation is the most obvious.Current draw box is generally deposited
Bigger temperature difference is there is at internal temperature, uneven to tow heating, reduce drawing effect, have impact on high-strength polyethylene fine
Dimension, carbon fiber and the quality of aramid fiber product.
Summary of the invention
