Abstract
The invention discloses a method for producing a semi-dull high-speed spinning domestic section by polymerizing caprolactam. The method is characterized by comprising the following steps: fusing the caprolactam and arranging the fused caprolactam to a configuration tank with an anchor agitator according to the formula; conveying various materials required by the formula to the agitator by a flowmeter, mixing the materials horizontally and longitudinally in all directions by the circulation of a conveying pump and the anchor agitator to fully mix the materials, adding a precise filter to the configuration tank, and feeding the materials into a polymerizing system. For solving problem in the conventional process, the caprolactam is arranged in the configuration tank with a dynamic agitator after being fused; various materials required by the formula are conveyed into the agitator by the flowmeter to be fully mixed by the circulation of the conveying pump and the anchor agitator; and the precise filter is added to the configuration tank to feed the materials into the polymerizing system, so that the quality of the section is improved.
Description
Technical field
The invention belongs to polymkeric substance synthetic and modification field, the particularly method of the civilian section of a kind of caprolactam polymerization production half delustring high-speed spinning.
Background technology
The civilian slice process of tradition caprolactam polymerization production half delustring high-speed spinning is filled a prescription after the hexanolactam melting and is passed through under meter, in pipeline, pass through static mixer, directly enter paradigmatic system after the mixing, the easy like this foreign material that produce when pipe-line blending are because entering paradigmatic system without strainer, simultaneously, pipeline static mixer causes chipping qualities unstable to prescription material undercompounding.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides the method for the civilian section of the high caprolactam polymerization production of a kind of quality product half delustring high-speed spinning.
The present invention realizes by following technology:
The method of the civilian section of a kind of caprolactam polymerization production half delustring high-speed spinning, it is characterized in that: with after the hexanolactam melting by formulating of recipe to a batch tank with anchor stirrer, the various mass transport that prescription needed by under meter again are in agitator, by transferpump beat circulation and anchor stirrer realization material laterally, longitudinally comprehensive mixing, thereby material is fully mixed, behind batch tank, add an accurate filter again, then make material enter paradigmatic system.
The filtering accuracy of described accurate filter is 3 μ m.
Compared with prior art, the invention has the beneficial effects as follows: for the existing problem of traditional technology, putting into one with the batch tank of dynamic agitator by formulating of recipe after the hexanolactam melting, the various mass transport that prescription needed by under meter again are in agitator, play circulation and anchor formula whipping appts realization material is horizontal by transferpump, longitudinally comprehensive mixing, thereby material is fully mixed, behind batch tank, add an accurate filter again, then make material enter paradigmatic system, thereby improved chipping qualities, the civilian chipping qualities of half delustring high-speed spinning that adopts this method to produce is good, can satisfy need of production.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing 1 is the conventional process flow figure of the civilian section of caprolactam polymerization production half delustring high-speed spinning;
Accompanying drawing 2 is the process flow sheet of the civilian section of caprolactam polymerization production half delustring high-speed spinning of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention will be further described.
Embodiment:
After the hexanolactam melting, respectively be metered into batch tank with anchor stirrer in 0.25% ratio by under meter in prescription with titanium dioxide and phenylformic acid, the various mass transport that prescription needed by under meter again are in agitator, after making circulation and anchor formula whipping appts and stir 60 minutes by transferpump, after piping accurate filter (CDF-PA-10D, filtering accuracy 3 μ m) filtration, enter again paradigmatic system.
The civilian section of half delustring high-speed spinning of adopting this method to produce has just guaranteed that from the feed(raw material)inlet homogeneity, the particularly titanium dioxide dispersion in section of mixing of materials improves a lot, and guarantees downstream client's spinning property, dyeability.Thereby improved chipping qualities, the civilian chipping qualities of half delustring high-speed spinning that adopts this method to produce is good, can satisfy need of production.
Claims (2)
1. the method for the civilian section of caprolactam polymerization production half a delustring high-speed spinning, it is characterized in that: with after the hexanolactam melting by formulating of recipe to a batch tank with anchor stirrer, the various mass transport that prescription needed by under meter again are in agitator, by transferpump beat circulation and anchor stirrer realization material laterally, longitudinally comprehensive mixing, thereby material is fully mixed, behind batch tank, add an accurate filter again, then make material enter paradigmatic system.
2. the method for the civilian section of caprolactam polymerization production half delustring high-speed spinning according to claim 1, it is characterized in that: the filtering accuracy of described accurate filter is 3 μ m.
