Description
Technical field
The utility model relates to a kind of equipment for preparing fibrous material, says further, relates to a kind of equipment for preparing polyether sulfone fiber.
Background technology
(polyether sulfone is amorphism, amber, transparent homopolymers PES) to polyethersulfone resin, has comprehensive excellent properties.The construction unit of polyether sulfone is:
The PES resin is a kind of heat resistance speciality polymer material with excellent flame retardancy.Its heat resistance is outstanding, and heat distortion temperature is 200～220 ℃, can use at 180～200 ℃ long-term.Creep-resistant property is good under the high temperature, and under 150 ℃, the stress effect of 19.99MPa, its strain has only 2.55%, and its creep resistance is the most excellent a kind of in the thermoplastic resin in the temperature range below 180 ℃.In temperature environment jumpy, still can keep outstanding advantages such as stable performance.Goods are transparent, dimensionally stable, hot water or steam that can be anti-150～160 ℃, its modulus 100～200 ℃ almost constant, especially all better more than 100 ℃ than any thermoplastic resin.Ageing-resistant performance is also excellent, can reach 20 years 180 ℃ of service lifes.PES resin limited oxygen index is 38, has self-extinguishment, and not adding any fire retardant promptly has excellent flame.Its chemical resistance is good, except that can anti-dilute sulfuric acid, the rare nitric acid, dense, watery hydrochloric acid, also can anti-50%NaOH, 50%KOH, inorganic acid alkali such as liquefied ammonia and ammoniacal liquor, the ability of anti-organic reagent also is better than the common engineering plastics, as can anti-various alkane, petroleum product, alcohols, benzene, acetate, chloroform and carbon tetrachloride etc.Anti-steam and superheated water (150～160 ℃) performance is also fabulous, can be through repeatedly moise-heat sterilization.But chemical nickel plating and copper facing.The x radiation x of anti-r performance might as well.But the UV resistant performance is poor.Aspect sanitary standard, approved by U.S. FDA, also meet the requirement of No. the 434th, Japanese health ministry and No. 178 bulletins.Mechanical property and electrical property are good, its typical physical and chemical performance is: relative density 1.37, TENSILE STRENGTH 84MPa, bending strength 12.4MPa, cantilever beam impact strength (breach) 85.3J/m, Rockwell hardness M88, water absorption rate (24h) 0.43%, 203 ℃ of heat distortion temperatures (1.82MPa), relative dielectric constant 3.5, specific insulation 10

The special engineering plastics polyether sulfone all is very superior at aspects such as heat resistance, chemical proofing and mechanical performances, and it is thermoplastic resin, and processing and forming is good, so the demand in the field that high-performance, high reliability request are arranged is in continuous growth.The main application fields of PES has electrical equipment, electronics, mechanical field, automotive field, hot water field, medical apparatus, food processing machinery field, film separation field.
The goods of PES resin only limit to special type (heat resistant type) engineering plastics, coating and filter membrane at present.Its engineering plastics can with inject, extrude, method processing such as mold pressing, vacuum forming, the processing of coating and filter membrane then needs wiring solution-forming.The hollow PES fiber that the kind of like fibrous has only ultrafiltration still at the experimental stage to use, it is the diameter (about 1mm) made by the solution spinning wet moulding filtering material much larger than general fibre (diameter is 10～30 μ m), and its processing technology and performance requirement and general fibre are also incomplete same.Abroad the report about the polyether sulfone melt-spun has only one piece [1], has wherein studied the incompatible additive that adds in PES less than 1%, and PES just can stablize spinning, and the gained fibre strength is 2.1CN/dtex.Domestic research report about the polyether sulfone melt spinning is also few, has only Tianjin to spin institute and made experimental study on fusion index instrument.(" polyether sulfone fiber development ", Yu Jianming etc., Tianjin Textile Industry College institute newspaper, 1996,15 2.: 14～17)
The difficulty of fusion method spinning polyether sulfone fiber mainly is at present:
1, polyethersulfone resin processing temperature height.And the single screw extrusion machine that the spinning of using is at present used and the serviceability temperature of supporting filament spinning component are limited in below 350 ℃, and the processing temperature of PES is 330～370 ℃, and spinning temperature is then higher, need at 340～380 ℃.
2, melt viscosity is big.Behind the PES heating and melting, viscosity is bigger, and the melt fracture tendency is arranged, and spinnability is poor.And by improve spinning temperature reduce melt viscosity method since the existence of thermal decomposition be difficult to realize.
3. difficult feed in the commonly used fusion apparatus-single screw extrusion machine of spinning technique.PES is unformed macromolecular material, and no fusing point takes place softening in a wider temperature range.Therefore reaching the easy loops resistance material that takes place under the condition of abundant fusion.
