Product Description
Trisodium phosphate
Chinese name:
Trisodium phosphate
Foreign name:
trisodium phosphate anhydrous
Chemical formula:
Na3PO4·12H2O or Na3PO4
When the crystals of
trisodium phosphate dodecahydrate loses twelve crystal waters at 100 ° C, they
become anhydrate (Na3PO4).

requirements.
Application field
-
The quality
improving agent of the work has the effects of improving the complex metal ions
of the food, the pH value, and increasing the ionic strength, thereby improving
the cohesiveness and water holding capacity of the food. China regulations can
be used for cheese, large use 5g / kg; in Western ham, meat, fish, shrimp and
crab. Large use of 3.0g / kg; in cans, juice, beverages and dairy products.
Large use It is 0.5g/kg.

Used as softener
and detergent in boiler, chemical, textile, printing and dyeing, papermaking,
power generation, boiler anti-scaling agent, soft water agent in paper dyeing,
pH-based buffer for producing adhesive for wax paper, printing and dyeing
Fixing agent, mercerizing enhancer for fabric, anti-brittle agent for line
making. The metallurgical industry is used as a chemical degreasing, decontamination,
and as an excellent accelerator in photographic developing solutions. Detergent
for tooth cleaners and bottlers. A coagulant for rubber latex. Sugar juice
purifier. Phosphate plays a role in quality improvement in food processing. For
example, in meat products, it maintains the water holding capacity of the meat
and enhances the binding force to reduce the loss of nutrients in the meat and
preserve the tenderness of the meat. It is also used as an emulsifier, a
nutritional supplement, and a quality improver in food processing. It is a raw
material for the preparation of edible alkali water, and is also used for the
manufacture of sugar and the production of α-starch. It is also used as a
detergent for food bottles, cans, and the like.

Solid trisodium
phosphate (TSP) is a strong base weak acid salt with strong alkalinity and high
solubility. It is chemically stable and can be stored for a long time. It is
added in the spray water of the safe shell spray system (EAS). Instead of NaOH,
TSP can adjust the pH of the spray solution, effectively remove the iodine gas
released from the leaked cooling water to the containment, avoiding the damage
of the strong alkali to the staff, and easy to clean after the accident.
Store in a cool,
ventilated warehouse. Keep away from fire and heat. The package is sealed and
must not be in contact with air. Moisture-proof and sun-proof. It should be
stored separately from acids and the like. It should be lightly loaded and
unloaded during handling to prevent damage to packaging and containers. The
warranty period is 24 months.
