Appication
For boiler Water treatment,
Monosodium Phosphate(MSP),Disodium phosphate(DSP),Trisodium phosphate(TSP) all could be used for boiler water treatment. MSP is used as control of anode corrosion,DSP is as control of alkali corrosion ,TSP is as softer of calcium and magnesium ion precipitation.TSP is with the largest usage.
MSP and DSP keep proper alkali value and prevent more hydroxide ion.
TSP is to prevent calcium and magnesium precipitation.From phosphate protective film inside boiler to prevent corrosion.

DAP is the most concentrated phosphate-based fertilizer. It is perfect for any agricultural crop to provide phosphorus nutrition throughout crop growth and development, as well as starter dose of nitrogen and lower sulphur.

It can be applied in autumn for tilling and in spring during sowing, as well as pre sowing cultivation. Dissolving in soil, it provides temporary alkalization of pH of the soil solution around the fertilizer granule, thus stimulating better uptake of phosphorus from the fertilizers on acid soils. Fertilizer's sulphur also contributes to the better intake of nitrogen and phosphorus by plants.

Packing: 25kg bags, 50kg bags, 1200kg jumbo bags, and customer's marking bags.

Handling and Storage: Store in a cool and dry place, away from moisture, heat. Protect the materials from the sun or rain during transportation.

Diammonium phosphate, commonly referred to as (DAP 18-46), is the world's most used phosphate fertilizer. As a primary nutrient, DAP helps the plant to capture and convert the sun's energy into useful compounds for the plant. It also stimulates root development and enhances the durability of the stems.
Usage: In addition to its wide usage in the agricultural sector, DAP is also used to impregnate matches, and as a flame-retardant (for fighting forest fires).

DAP NH42HPO4 is a light brown granular phosphatenitrogen compound fertilizer produced by neutralizing phosphoric acid with ammonia

The phosphate is well soluble in water while the nitrogen content is in ammonium form P nutrient availability is ensured for crop rotation at the same time as nitrate fertilization
DAP can be used for all types of crop and all kinds of soil and should be applied during nitrogen fertilization in the spring or autumn

High quality contains fully watersoluble highly concentrated phosphate
Good transport and storage qualities nonhygroscopic nondustforming does not tend to cake
Good spreading behavior thanks to a balanced range of granule sizes
Suitable for fertilizer mixes thanks to excellent granular properties

Diammonium phosphate (DAP) is a widely used fertilizer that provides a high concentration of phosphorus and nitrogen nutrients. It is composed of two ammonium ions and one phosphate ion. DAP is a water-soluble salt and is often used in agricultural settings to enhance plant growth. Here are some key points about diammonium phosphate:
Nutrient Composition: Diammonium phosphate is a good source of both nitrogen and phosphorus, with nitrogen content in the ammonium form and phosphorus in the phosphate form.
The nitrogen in DAP is readily available for plants, while phosphorus is essential for root development, flowering, and fruiting.
Solubility: Diammonium phosphate is highly water-soluble, making it easy to apply as a liquid fertilizer or to dissolve in irrigation systems.
pH and Acidity: DAP tends to be slightly acidic, which can contribute to lowering the pH of the soil over time. It is essential to monitor soil pH when using fertilizers to prevent overly acidic conditions.
Application: DAP is commonly used as a dry granular fertilizer that can be broadcast on the soil surface.
It can also be dissolved in water and applied as a liquid fertilizer through irrigation systems, providing quick nutrient availability to plants.
Uses: Diammonium phosphate is suitable for a variety of crops, including grains, fruits, vegetables, and legumes.
It is often used during the early stages of plant growth to promote root development.
Storage: DAP should be stored in a cool, dry place to prevent moisture absorption and caking.
Safety Considerations:

When handling DAP, it's important to follow safety guidelines and use appropriate protective equipment to prevent skin or eye contact and inhalation.
Compatibility: Diammonium phosphate is compatible with many other fertilizers and can be used in combination with them to provide a broader spectrum of nutrients.
Environmental Impact: Like other fertilizers, the application of DAP should be done responsibly to minimize environmental impact, such as nutrient runoff into water bodies.
