Notch filters (BEF, band inhibition) can transmission most wavelengths, but attenuates light to very low levels in a specific wavelength range (BEF). Notch filters, in contrast to band-pass filters, only inhibit light in a narrower wavelength range.
Dipping is a heating process. When the metal is preheated, dip-molded, and the material is heated, the metal sticks to the surrounding materials. The hotter the metal, the longer the dipping time and the thicker the material. Naturally, the temperature and the shape of the dip are the key to determining how much to stick to the plastisol. A dip shape can be created by dip.
The dip material is a variety of plastic powders. We call it dip powder, which is mainly used for clothing hanging, bicycle, basket, kitchen utensils, etc., with good leveling and gloss. Engineering powder is used for the coating of highways and railway guardrails, municipal engineering, instrumentation, supermarket grids, shelves in refrigerators, cables, miscellaneous goods, etc., with durability and corrosion resistance.
The raw materials for heating dip powder are: PE general-purpose dip powder, PE engineering dip powder, PE pipeline type dip powder, PE refrigerator special dip powder, PE hanger special dip powder.
This process of applying plastic powder to a metal surface to achieve corrosion protection is called dip molding. Do you know now?
