Urea staining method
Thread Content
Exploration of urea staining methods: 1. Internal staining with no external coloring aid； Internal dyeing uses dyes and pigment pastes as coloring sources. 2. There is no internal coloring; external coloring is the main method, with resin coating and sustained-release coating serving as the sources of color. Which of the two methods is more effective and has lower costs? What is the tonnage usage? How much will the cost increase? Friends who have used urea dyeing, please discuss and reply. :handshake
Grinding the pigment directly mixed with urine results in the lowest cost.
Have you used this method, or has a friend of yours used it? Thank you!
We mainly produce internally dyed products here. Our key products include peptide urea, energy-releasing slow-release urea, zinc humic acid urea, humic acid urea, Fenghui urea, special fertilizers for wheat, special fertilizers for corn, etc. All of these are made by adding various ingredients to urine. The process is also simple, with only a minor increase in cost. We do not produce resin-coated sustained-release coatings here.
Poster: The dye can be directly added from an evaporation inlet at one end. The product’s color effect is excellent. As for costs and usage amounts, please consult the relevant technology suppliers; our factory uses a patent from a company in Beijing.
I disagree with dyeing; it increases costs, is useless, and harms the ecosystem. Standing from the farmers' perspective is a form of deception.
Indeed, some fertilizer products today are highly deceptive in appearance; they actually provide no real benefit and only increase costs, with the public having to bear those expenses.
