Az alufólia utófeldolgozása egy vállalkozás fontos része, amely egy alumínium vállalkozás hozamához és a vállalkozás profitpontjához kapcsolódik. Minél nagyobb a hozam, minél magasabb a vállalkozás profitpontja. természetesen, a hozamrátát minden linkben ellenőrizni kell, szabványosított működés, és kifinomult felszerelésre és felelős vezetőkre és alkalmazottakra van szükség. I don’t understand the equipment and operating specifications, and I dare not point fingers at them. I can only analyze it according to practice on the slitting knife. Következő, I will talk about why the slitting will produce edge, multilateral, and powder drop.
The problems of warping edges, sokszögek, and powder dropping are mostly related to the blades, except for the problems of the material itself and the equipment. Usually there are two kinds of blades for aluminum foil slitting. One is a round blade, and the other is a dicing blade, also called a razor. The razor blade is fixed at a point and passively cuts and slashes by winding the material. Aluminum foil is actively slitting, and the faster the speed, the lower the resistance of the blade. The slower is the opposite. The thickness of the blade corresponds to the resistance. The thicker the blade, the greater the resistance. The thinner is the opposite. Since the razor blade is fixed and fixed, when the blade is in contact with foil or thin materials, the cutting point is prone to fatigue and heat, so after a period of time, the blade will not be sharp, the blade will be blunt and will tear and powder will drop. Raw edges are inevitable. természetesen, these are also related to the slitting angle. Choosing a good razor blade is the first choice to solve these problems, and ceramic blades should be the first choice.
Jelenleg, all aluminum foil companies want to process high value-added battery foils, but the battery foil acceptance standards are harsh. Representative lithium battery companies like BYD, ATL, and A123 battery cell companies have harsh acceptance standards for aluminum foil. The requirements for foil are extremely high, and the width, dust, and edge warping are also harsh among the harsh. Ebből adódóan, for battery foil companies with low output, the yield of post-processing and slitting is very important.
