In actual production, pole piece P has collector P1 and at least one film area P2 being arranged on collector P1, such as
Shown in Fig. 1 and Fig. 2, the quantity of diversion trench 31 is accordingly determined for the film area P2 quantity of pole piece P, and different slurries applies
Linkage section can accordingly be designed there are a variety of situations for these situations by covering the film area P2 distribution of weight of the pole piece P
The distance of the position of 311 flow-disturbing protrusion S, quantity and protrusion, only exemplarily introduces three kinds of embodiments below.Implement one
In example, linkage section 311 is formed there are one flow-disturbing protrusion S, and flow-disturbing protrusion S to be located at the opening with diversion trench 31 of linkage section 311
The opposite position in 312 centers.
In another embodiment, linkage section 311 is formed with spaced apart three flow-disturbing protrusions S, three flow-disturbing protrusions S
In the position opposite with 312 center of opening of diversion trench 31 of linkage section 311 and in intermediate flow-disturbing protrusion S-phase for both sides
Flow-disturbing protrusion S it is prominent to the opening 312 of diversion trench 31 distance it is big.
In another embodiment, linkage section 311 is formed is located at linkage section there are three flow-disturbing protrusion S, three flow-disturbing protrusion S
311 position opposite with 312 center of opening of the diversion trench 31 and opening 312 of three flow-disturbing protrusion S to diversion trench 31 is prominent
Distance it is incremented by successively from Inside To Outside.
Above-mentioned three kinds of embodiments can with the diversion trench 31 of different number, different position formed multiple combinations, below only with
Gasket 3 introduces three kinds of combinations therein exemplified by forming three diversion trenches 31.
In one embodiment, when apparatus for coating (is used as shown in figs.10 and 14 using the gasket 3 of the prior art
Gasket 3) for a kind of slurry production pole piece P film area P2 Mass Distributions as shown in Figure 17 when, the film of left, center, right three
Convex distribution is presented in area P2, it is therefore desirable to reduce the weight of each film area P2 intermediate regions, increase each film area P2 marginal zones
The weight in domain, accordingly, the design form of gasket 3 is as shown in Fig. 9 and Figure 13, i.e.,：Diversion trench 31 is three, three diversion trenches
31 arranged for interval in left-right direction, each diversion trench 31 in be equipped with linkage section 311, and each linkage section 311 forms that there are one flow-disturbings
Protrusion S, each flow-disturbing protrusion S are located at the position opposite with 312 center of opening of diversion trench 31 of linkage section 311.Using Fig. 9 and
The apparatus for coating of gasket 3 shown in Figure 13 is coated, and result of the test is as shown in figure 18, it is observed that in each film area P2
Between the weight in region become smaller, the weight of fringe region becomes larger, and effectively improves convex distribution.
Similarly, in another embodiment, when apparatus for coating (uses such as Figure 10 and figure using the gasket 3 of the prior art
Gasket 3 shown in 14) for the pole piece P of another slurry production film area P2 Mass Distributions it is as shown in figure 19 when, it is left, in,
U-shaped distribution is integrally presented in the three film area P2 in the right side, it is therefore desirable to the weight of left and right Liang Ge films area P2 is reduced, and closer to side
Edge region needs reduced amplitude bigger, accordingly, the design form of gasket 3 as shown in figs. 8 and 12, i.e.,：Diversion trench 31 is
Three, three diversion trenches 31 arranged for interval in left-right direction, two diversion trenches 31 positioned at the both sides of left and right directions are interior respectively to be set
Have a linkage section 311, the tool of linkage section 311 there are three flow-disturbing protrusion S, three flow-disturbing protrusion S be located at linkage section 311 with diversion trench 31
The opposite position in 312 center of opening and three flow-disturbing protrusion S it is prominent to the opening 312 of diversion trench 31 distance it is outside from inside
Side is incremented by successively.It is coated using the apparatus for coating of the gasket 3 shown in Fig. 8 and Figure 12, result of the test is as shown in figure 20, can be with
It observes that the distribution of weight of each film area P2 reaches unanimity, effectively improves U-shaped distribution.
