Who has green diammonium phosphate?
Thread Content
As the title suggests, does anyone have green diammonium? Is this primary color its natural color or is it green-dyed? Thank you
We don’t have any. We do have those green bags, but they must be dyed!
Uncolored diammonium compounds are related to the color of phosphoric acid; they are generally white. If the phosphoric acid is dark in color, then the compound will also be dark in color. It seems that there is no natural green color available
I heard from people at Wengfu that ordinary diammonium fertilizers don’t have this color; the green diammonium fertilizers available on the market are all colored.:
The green ones are there; they are colored. It has been done before. Most of Wengfu’s products are yellow and brown
It is made from emerald green DAP and Kaoyuan red phosphorus, intended for the Vietnamese market; the production volume is around several tens of thousands of tons per year, and it is achieved through dyeing. The natural color of Tianhu Lake is a bit green.
Isn’t everyone talking about true-color diammonium these days? No coloring is needed.
I’ve never heard of it, but it shouldn’t be difficult to do; a suitable coloring agent formula should work
Is emerald green DAP colored using emerald green pigment or something similar? I also want to find this kind of pigment; I’ve searched online for a long time without success. Do you know where it can be found? Thank you!
Fertilizer colorants can be obtained from Tianjin Dye Research Institute, Shanghai Dye Research Institute, and Huizhou Lüjing Industrial Co., Ltd. (0752-25594990)
