Abstract
The present invention relates to a kind of carbon fibre precursor spinning, belong to carbon fibre precursor spinning field.Its step includes：（1）Dimethyl sulfoxide (DMSO) and pure water are squeezed into coagulating basin by pump group, ON cycle pump group, dimethyl sulfoxide concentration control is between 60% 70%；（2）Setting temperature is controlled between 35 DEG C 40 DEG C by fluid heater and cold-water heat exchanger；（3）The speed of a roller is drawn in adjustment, residence time of the tow in solidification liquid is controlled between 50S 70S；（4）Increase ultrasonic generator in coagulating basin rear end, tow is drawn and drawn after a machine roller, open ultrasonic generator.The present invention clotting method spinning, obtained precursor lousiness is few, intensity height.
Description
Technical field
It is particularly a kind of efficient clotting method of wet spinning the present invention relates to carbon fibre precursor spinning field.
Background technology
It is well-known：With carbon fiber, more and more, quality requirement of the application field to carbon fiber is applied in market at home
More and more higher, carbon fiber quality quality greatly depend on precursor quality height, therefore be made high-quality precursor into
The emphasis developed in recent years for the country.The quality height of precursor greatly depends on the quality of coagulation result, but existing
Method coagulation result it is less desirable, obtained precursor lousiness is more, and intensity is not very high.
The content of the invention
The purpose of the present invention, which is that, overcomes the deficiencies in the prior art there is provided a kind of carbon fibre precursor spinning, is solidified with this
Method spinning, obtained precursor lousiness is few, and intensity is high.
The present invention uses following technical solution：A kind of carbon fibre precursor spinning, its step includes：（1）Pass through pump group
Dimethyl sulfoxide (DMSO) and pure water are squeezed into coagulating basin, ON cycle pump group, dimethyl sulfoxide concentration is controlled between 60%-70%；
（2）Setting temperature is controlled between 35 DEG C -40 DEG C by fluid heater and cold-water heat exchanger；（3）A roller is drawn in adjustment
Speed, residence time of the tow in solidification liquid is controlled between 50S-70S；（4）Increase ultrasonic wave in coagulating basin rear end
Generating means, draws tow and draws after a machine roller, opens ultrasonic generator.
The beneficial effects of the invention are as follows with the clotting method spinning, obtained precursor lousiness is few, and intensity is high.
Embodiment one：
（1）Dimethyl sulfoxide (DMSO) and pure water, ON cycle pump group, dimethyl sulfoxide concentration control are squeezed into coagulating basin by pump group
65%；（2）Setting temperature is controlled at 35 DEG C by fluid heater and cold-water heat exchanger；（3）The speed of a roller is drawn in adjustment
Degree, makes residence time of the tow in solidification liquid control at 60 seconds；（4）Increase ultrasonic generator in coagulating basin rear end,
Tow draws after a machine roller, opens ultrasonic generator.
Comparative example one：Operated by above-mentioned steps, wherein step（4）Increase ultrasonic wave at 1/4 before coagulating basin.
Comparative example two：Operated by above-mentioned steps, wherein step（4）Increase ultrasonic wave at 2/4 before coagulating basin.
Comparative example three：Operated by above-mentioned steps, wherein step（4）Increase ultrasonic wave at 3/4 before coagulating basin.
Comparative example four:Operated by the first three steps of embodiment one, whole coagulating basin does not increase ultrasonic unit.
Embodiment one, comparative example one, comparative example two, comparative example three, comparative example four how many and intensity the relations of lousiness such as
Shown in table 1：
Table 1
| Position of the Vltrasonic device in coagulating basin from front to back | Lousiness situation | Precursor intensity, cN/dtex | |
| Comparative example one | Increase ultrasonic wave at 1/4 before coagulating basin | It is very many | 5.1 |
| Comparative example two | Increase ultrasonic wave at 2/4 before coagulating basin | It is more | 6.5 |
| Comparative example three | Increase ultrasonic wave at 3/4 before coagulating basin | It is less | 7.5 |
| Embodiment one | Increase ultrasonic wave at 4/4 before coagulating basin | Nothing | 7.8 |
| Comparative example four | Without Vltrasonic device | Nothing | 7.2 |
As can be seen that in coagulating basin rear end from comparative example one, comparative example two, comparative example three, embodiment one and comparative example four（I.e.
4/4 before coagulating basin）Position increase ultrasonic wave, no lousiness, precursor intensity highest；Without Vltrasonic device at coagulating basin, no lousiness,
Strength ratio 4/4 before coagulating basin at increase ultrasonic wave it is lower slightly.
As can be seen that respectively 1/4,2/ before coagulating basin from comparative example one, comparative example two, comparative example three, embodiment one
4th, increase Vltrasonic device at 3/4,4/4, lousiness is gradually decreased, and precursor intensity gradually rises, 4/4 before coagulating basin at without lousiness,
Precursor intensity highest.
Any concentration of the dimethyl sulfoxide concentration of the present invention between 60%-70%；Setting temperature control 35 DEG C -40 DEG C it
Between any temperature；Residence time of the tow in solidification liquid controls any duration between 50S-70S；Respectively 1/ before coagulating basin
4th, increase Vltrasonic device and without Vltrasonic device at 2/4,3/4,4/4, measured in the case of identical concentration, temperature, duration
Result be consistent with table 1.
