Consistency be affected, whether coating smooth to determine back segment process speed of production, and whether coating pole piece surface density uniformly determines
The consistency of battery core capacity is determined.Therefore, painting process produces lithium ion battery most important.
The character of slurry largely affects the stability of coating.General lithium ion battery produces painting process
In, usually slurry is squeezed into buffer tank by diaphragm pump, slurry generally uses 100-200 mesh screen mistake when passing through diaphragm pump
Sieve, slurry in buffer tank filter out particle that may be present by screw pump conveying, using 80-150 mesh screen, slurry into
Enter coating machine die head to be coated.For character stabilization, smoothly slurry, the pole piece consistency for being coated with out are preferable for sieving.So
And slurry poor for character, that sieving is difficult, the consistency of ordinary circumstance inferior pole piece is also poor, simultaneously because sieving is difficult,
It is easy to that sieving network blocking phenomenon occurs, production spreading mass network blocking is mainly caused by following factor: (1) slurry settles；(2) it starches
Material dispersion is uneven；(3) dry mixing process slurry binder is not completely dissolved；(4) there are larger particles in slurry；(5) contain in slurry
More extremely fine particle leads to particle agglomeration；(6) for sieve itself due to using overlong time, mesh is difficult to clean defective material；
(7) conveying pump power is smaller；(8) conveyance conduit blocks.
Above-mentioned slurry network blocking can seriously affect production efficiency, need to readjust homogenate technique, using the behaviour such as sieving
Make examination to apply, in this way can neither rapid evaluation slurry be sieved effect, and will increase slurry scraps probability, to influence equipment just
It is often used.
