Abstract
The invention discloses a compound monofilament. The compound monofilament comprises a middle core layer and a skin layer, wherein the middle core layer is made from PET (Polyethylene Terephthalate) or PA6 (Polyamide 6) or PA66 (Polyamide 66); the skin layer is made from PVDF (Polyvinylidene Fluoride); and the middle core layer is coated with the skin layer. The compound monofilament disclosed by the invention comprises the middle core layer and the skin layer, so that the volume of the skin layer is naturally far less than the total volume of the compound monofilament; and the compound monofilament disclosed by the invention has the advantage of low production cost as the price of the PET, the PA6 and the PA66 is rather low relative to the PVDF, can be widely applied to a filter screen as the PVDF has the advantages of excellent inadhesion, chemical corrosion resistance, high temperature resistance, oxidation resistance, and the like and meets the requirement for coarse filtration of the filter screen on liquid.
Description
Technical field
The present invention relates to a kind of composite monofilament, particularly relate to the composite monofilament of using in a kind of screen pack.
Background technology
PPS(gathers stupid thioether) be a kind of High performance plastic resin, has coefficient of friction little, the advantage such as mechanical strength is high, high temperature resistant, corrosion-resistant, difficult combustion, Heat stability is good, electrical property are good, particularly in hygrothermal environment, strength retention can use under the high temperature of 150 degree for a long time more than 90%.Therefore, PPS is made into monofilament, is widely used in high temperature, high humidity, chemical attack etc. extremely in the screen pack under the rugged environment condition, can make screen pack have the characteristics such as good filtration effect, opposing strong acid-base, long service life.
But, because the cost of material of PPS is too expensive, make the suitable height of production cost of screen pack, therefore, existing screen pack can not get using widely.
Summary of the invention
The invention provides the lower composite monofilament of a kind of production cost, it has overcome the existing deficiency of background technology.The technical scheme that adopts that the present invention solves its technical problem is:
A kind of composite monofilament, it comprises the center core layer of being made by PET or PA6 or PA66 and the cortex of being made by PVDF, described cortex envelopes described center core layer.
Among one preferred embodiment: the cross-sectional area of described center core layer is 1:1 with the ratio of the cross-sectional area of described cortex.
Among one preferred embodiment: the intensity of this composite monofilament is 450-550kg/mm
2
Among one preferred embodiment: the percentage elongation of this composite monofilament is 20-50%.
Among one preferred embodiment: the shrinkage factor of this composite monofilament is 3-18%.
Among one preferred embodiment: be applied in screen pack, liquid is carried out coarse filtration.
The technical program is compared with background technology, and it has following advantage:
1. this composite monofilament comprises center core layer and cortex, and the volume of this cortex is far smaller than the cumulative volume of this composite monofilament naturally, and due to relative PVDF, the price of PET, PA6, PA66 is quite cheap again, and therefore, this composite monofilament has advantages of that production cost is low.Simultaneously, because PVDF has good not viscosity, the advantages such as chemical resistance, heat-resisting quantity and oxidative resistance, therefore, this composite monofilament can be widely applied on screen pack, satisfies screen pack to the requirement of the coarse filtration of liquid.
2. the cross-sectional area of described center core layer is 1:1 with the ratio of the cross-sectional area of described cortex, in the materials that farthest reduce this cortex, the physical and mechanical property that can guarantee this composite monofilament satisfies instructions for use, makes this composite monofilament have advantages of that production cost is low, long service life.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 has illustrated the overall schematic of a kind of composite monofilament of a preferred embodiment.
Fig. 2 has illustrated the cutaway view of cross section of a kind of composite monofilament of a preferred embodiment.
The specific embodiment
Please refer to Fig. 1, a kind of composite monofilament 100 of the present invention for the manufacture of becoming screen pack, carries out coarse filtration to liquid.This composite monofilament 100 is double-decker, and it comprises a center core layer 10 and a cortex 20.This cortex 20 envelopes this center core layer 10.This center core layer 10 is by the PET(polyethylene terephthalate) or PA6(nylon 6) or PA66(nylon 66) make.This cortex 20 is by the PVDF(Kynoar) make.
Please refer to Fig. 2, the cross-sectional area of this center core layer 10 is 1:1 with the ratio of the cross-sectional area of this cortex 20.Like this, this cortex 20 has physics, the mechanical performance that enough thickness can guarantee this composite monofilament 100.Simultaneously, this center core layer 10 can also farthest occupy the space at this composite monofilament 100 middle parts, reduces as wide as possible the use amount of this cortex 20, makes the production cost of this composite monofilament 100 reach minimum.
The intensity of this composite monofilament 100 is 450-550kg/mm
2
The percentage elongation of this composite monofilament 100 is 20-50%.
The shrinkage factor of this composite monofilament 100 is 3-18%.
Because PET, PA6, PA66 price are quite cheap, therefore, the production cost that this center core layer 10 can greatly reduce this composite monofilament 100 is set.
Have the advantages such as good chemical resistance, heat-resisting quantity, oxidative resistance, non-viscosity due to PVDF, therefore, this cortex 20 is set makes this composite monofilament 100 have the characteristics such as superpower high temperature resistant, acid and alkali-resistance, non-viscosity, can be widely used in screen pack.
The above, only for preferred embodiment of the present invention, therefore can not limit according to this scope of the invention process, the equivalence of namely doing according to the scope of the claims of the present invention and description changes and modifies, and all should still belong in the scope that the present invention contains.
