How many filtration types of phosphate slag produced in phosphate production?

Principle: use gravity to make the phosphating slag natural precipitation at the bottom of the pool, the supernatant is discharged. Applicable scene: slag volume is small, treatment requirements are not high occasions. Advantages: low cost, simple operation. Disadvantages: low efficiency, need to be left for a long time, slag water content is high.

How to control the concentration of pharmaceuticals through ampere-hour meter equipment

Through experiments to determine the amount of active ingredients in the drug solution consumed per unit of electricity (Ah) (such as g/Ah). Example: For every 1000Ah consumed, 5L of concentrated phosphate solution needs to be replenished to maintain the concentration. Proportioning factor (K): K = Make-up volume (L or g) Cumulative Ah K= Cumulative Ah Make-up volume (L or g)

Difference between blower and induced draft fan in electroplating production

Equipment Core Role Application Scenario Blower To force fresh air or process gas into the system - To provide oxygen for plating tanks (e.g. acid copper plating requires air agitation) - Maintains positive pressure in the workshop and prevents the entry of external contaminants Induced draft fan Extracts exhaust gases, acid mist or harmful gases from the system - Removes acid mist from plating ba

Hot-dip galvanizing principle

Hot-dip galvanizing is a surface treatment technique in which steel products are immersed in a molten zinc solution (at a temperature of approximately 450°C) to form a dense alloy layer through a metallurgical reaction between iron and zinc.

The necessity of cooling and passivation treatment after hot-dip galvanizing

If a high-temperature workpiece after hot-dip galvanizing is directly exposed to air for cooling, the zinc layer will produce internal stresses due to sudden cooling, resulting in cracking or deformation of the coating. Water or air cooling slows down the cooling rate, stabilizes the structure of the zinc-iron alloy layer, and prevents plating defects caused by stress concentrations.

The role of phosphatization

Phosphating treatment forms a dense phosphate film (such as zinc phosphate or iron phosphate film) on the metal surface through a chemical reaction, blocking oxygen and moisture from direct contact with the metal and slowing down the rate of corrosion of the substrate, which is especially suitable for short-term rust prevention needs.

The role of passivation in electroplating

Passivation is a key step in the post-processing of electroplating, which significantly improves the corrosion resistance, appearance stability and functionality of the plated parts by forming a dense protective film on the surface of the metal plating.
