Application Scenarios and Technical Solutions for Watering Cans in Chemical & New Materials Industry

Precision Fertilizer and Chemical Application in Agriculture

In controlled-environment agriculture (greenhouses and vertical farms), watering cans equipped with fine rose heads (0.5mm to 1.0mm holes) are used to apply liquid fertilizers and foliar feeds. The solution lies in using corrosion-resistant materials like 304 stainless steel or UV-stabilized PP to prevent chemical degradation. For example, a 2-liter stainless steel can with a detachable brass rose is ideal for applying low-concentration nitric acid-based fertilizers without rusting.

Industrial Coolant and Solvent Dispensing

In small-scale manufacturing and laboratories, watering cans serve as manual dispensers for cutting fluids, coolants, and cleaning solvents. The key solution is to use HDPE cans with chemical-resistant seals and long, narrow spouts to direct flow into machine reservoirs. A 5-liter HDPE can with a 20mm diameter spout is a standard solution for dispensing water-based coolants in CNC machining workshops.

Dust Suppression and Surface Wetting in Construction

For construction sites handling cement, plaster, or dry powders, large-capacity (10-15 liter) galvanized steel watering cans are used for dust suppression. The solution involves using a coarse rose (3mm holes) to create a heavy droplet pattern that settles dust without creating puddles. The galvanized coating prevents reaction with alkaline materials like lime.
