Preferably, described cooling processing is cooling for carrying out at normal temperatures.
Preferably, described one-level is cleaned as washing.
Preferably, described secondary cleans as spinnerets is invaded in triethylene glycol, under the condition of heating, cleans.
Preferably, described heating-up temperature is 260 ℃.
Preferably, described three grades of cleanings are for utilizing buck to clean.
Preferably, described buck cleans and carries out in washing trough.
Preferably, the volume of described washing trough is 120L.
Preferably, described spinnerets cleaning method is washed after being also included in three grades of cleanings, and ventilation dries up.
In order to make those skilled in the art person understand better the technical scheme in the application, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only the application's part embodiment, rather than whole embodiment.Embodiment based in the application, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the application's protection.
Shown in ginseng Fig. 1, Fig. 1 is the process chart of a kind of spinnerets cleaning method one specific embodiment of the present invention.
The method comprises the steps:
S1., spinnerets to be cleaned is provided.On this spinnerets, offer some spinneret orifices, above-mentioned some spinneret orifices are uniformly distributed on spinnerets.In fabrication processes, this spinneret orifice is for exporting the spinning stretching.As a kind of embodiment, described spinneret orifice is divided into two groups, and described two groups of spinneret orifices are symmetrical.According to demand, in above-mentioned every group of spinneret orifice, the quantity of spinneret orifice can be designed as 24 or 36.Meanwhile, according to the service condition of the tow after minute fibre, described spinneret orifice can be designed as tri-angle-holed or trefoil hole; Or be designed to slotted eye or pancake hole.
S2 carries out pre-thermal decomposition process by spinnerets.This process is that lower step is carried out calcination processing process and prepared.
S3 calcines under the condition of high-temperature vacuum through the spinnerets of pre-thermal decomposition process.Under the hot environment of calcining, can there is decomposition reaction in some compounds, become the molecule of molecular weight, thereby be convenient to follow-up cleaning operation.In calcination process, can carry out calcine by steps, thereby the compound with different heat decomposition temperatures can both be decomposed fully.
S4 carries out cooling processing to the spinnerets through calcination processing.In above-mentioned cooling blowing, in normal temperature environment, carry out, so carry out coolingly, can save the energy.
After S5 is cooling, carries out one-level cleaning and dry up.One-level is herein cleaned as preliminary and is cleaned, and its cleaning process is specially: utilization has water and comes the conscientious flushing of spinnerets.Preferably, can adopt giant to carry out strong flushing to the spinneret orifice of spinnerets.
Spinnerets after S6 one-level is cleaned, then entered secondary and clean and three grades of cleanings.
Herein secondary clean to adopt chemical reagent to clean spinnerets, its essence is and utilize polarity good chemical reagent dissolves the small-molecule substance on spinnerets, in order to improve the dissolved efficiency of small-molecule substance, above-mentioned secondary cleaning process is carried out under heating condition, preferably, heating-up temperature is 260 ℃.The chemical reagent adopting is triethylene glycol, during cleaning, by above-mentioned spinnerets immersion and triethylene glycol solution, and keeps the regular hour.
Finally, carry out three grades of cleanings, above-mentioned three grades of cleanings are for utilizing buck to clean, to remove residual acidic materials.Above-mentioned acidic materials specifically comprise acid ion or acid compound.Further, above-mentioned three grades of cleanings are carried out in washing trough, and preferably, the volume of washing trough is 120L.During cleaning, the spinnerets cleaning through secondary is soaked in the washing trough that is contained with buck, through the regular hour, neutralization reaction is fully carried out, thereby reach cleaning performance more thoroughly.Because the product of neutralization reaction is mainly ion and water, what the two all can be relatively easy removes.
Spinnerets cleaning method of the present invention is washed after being also included in three grades of cleanings, to wash residual ion off, finally ventilates and dries up, and cleans complete.
In sum, compared with prior art, the invention has the beneficial effects as follows: a kind of spinnerets cleaning method of the present invention has effectively cleaned spinnerets, make spinnerets can keep certain precision and fineness, guaranteed carrying out smoothly of spinning production.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims rather than above-mentioned explanation, is therefore intended to include in the present invention dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limiting related claim.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should make description as a whole, and the technical scheme in each embodiment also can, through suitably closing, form other embodiments that it will be appreciated by those skilled in the art that.
