Although as a result, the situation of example 5 is to reduce stagnant areas body by arranging the extrusion coated machine part 1290 of slit
Product, but flow deviation is exacerbated, cause coating quality to decline.
Figure 24 by bar shaped illustrate in example 1 to example 5 it is various in the case of stagnant areas volume ratio.As above institute
State, the ratio in example 1 is 9.78%, the ratio in example 2 is 7.48%, and the ratio in example 3 is 4.81%, in example 4
Ratio be 11.18%, the ratio in example 5 be 3.78%.As can be seen that in addition to comparative example 4, from example 1 to example 5
Order, its effect is more and more significant.By this result it is recognised that the extrusion coated machine part of set slit
The ratio of 1290 longitudinal cross-section product is less, and the volume ratio of stagnant areas is less.It can be seen that minimum in sectional area ratio
The decrement of stagnant areas volume ratio is maximum in example 5.
Figure 25 is in the case of various in example 1 to example 5, according to the outlet from outlet centre distance width
Relative discharge distribution curve map.Its display, example 1, example 2 be not provided with the extrusion coated machine part 1290 of slit
The flow distribution curve of example 4 is almost consistent.And, by the flow distribution curve of example 3 that the ratio of sectional area is 23.0%
When being compared with example 4, the flow distribution curve of example 3 does not deviate considerably from the curve of example 4, illustrates almost identical song
Line number value.This explanation, the situation of example 1 to example 3, relative to the feelings for being not provided with the extrusion coated machine part 1290 of slit
Condition, the flow distribution in the exit after the extrusion coated machine part 1290 of slit is arranged is not apparent from change, that is, apply thickness
The constancy of degree is not apparent from reducing.But it is recognised that relative to example 4, the flow deviation of example 5 is big.The outlet of example 5
The standard deviation of the mean value of 1250 rate of discharge is 2.19%, and the slurry flow deviation that exit spues is held beyond quality
Perhaps a reference value.Thus, it is possible to say, although the situation of example 5 is reduced by arranging the extrusion coated machine of slit with part 1290
Stagnant areas volumes, but flow deviation is exacerbated, cause the coating quality to reduce.
Based on the above it is recognised that with the plane cutting vertical with the width of outlet, i.e. first direction
In the sectional area for extending to first side from inclined plane formed during portion space 1240, so that closest to during three sides
Sectional area be closest to inner space 1240 central part when sectional area 23.0% to 53.7%, i.e., sectional area A for cut
When the mode of the 23.0% to 53.7% of area B is arranged on incline structure inside the extrusion coated machine of electrode production slit,
