(Tri) Sodium Phosphate
Trisodium phosphate এর বিভিন্ন প্রয়োগ রয়েছে তবে এটি প্রাথমিকভাবে একটি ক্লিনিং এজেন্ট, খাদ্য সংযোজনকারী, দাগ অপসারণকারী এবং ডিগ্র্রেজার হিসাবে ব্যবহৃত হয়। অসেপটারার ট্রাইসোডিয়াম ফসফেট একটি শ্বেত, দানাদার বা স্ফটিকের শক্ত, ক্ষারযুক্ত দ্রবণ উত্পাদনকারী পানিতে অত্যন্ত দ্রবণীয়।
Trisodium phosphate and other sodium phosphate additives have multiple uses in the food industry and are found in many commercially prepared products. They are used to decrease acidity and improve texture in foods such as baked goods and meats.
Cleaning
Trisodium phosphate was at one time extensively used in formulations for a variety of consumer-grade soaps and detergents, and the most common use for trisodium phosphate has been in cleaning agents. The pH of a 1% solution is 12 (i.e., very basic), and the solution is sufficiently alkaline to saponify grease and oils. In combination with surfactants, TSP is an excellent agent for cleaning everything from laundry to concrete driveways. This versatility and low manufacturing price made TSP the basis for a plethora of cleaning products sold in the mid-20th century.
TSP is still sold and used as a cleaning agent, but since the late 1960s, its use has diminished in the United States and many other parts of the world because, like many phosphate-based cleaners, it is known to cause extensive eutrophication of lakes and rivers once it enters a water system.
TSP is commonly used after cleaning a surface with mineral spirits to remove hydrocarbon residues and may be used with household chlorine bleach in the same solution without hazardous reactions.[citation needed] This mixture is particularly effective for removing mildew, but is less effective at removing mold.[citation needed]
Although it is still the active ingredient in some toilet bowl-cleaning tablets, TSP is generally not recommended for cleaning bathrooms because it can stain metal fixtures and can damage grout.
Flux
In the U.S., trisodium phosphate is an approved flux for use in hard soldering joints in medical-grade copper plumbing. The flux is applied as a concentrated water solution and dissolves copper oxides at the temperature used in copper brazing. Residues are water-soluble and can be rinsed out before plumbing is put into service.
TSP is used as an ingredient in fluxes designed to deoxygenate nonferrous metals for casting. It can be used in ceramic production to lower the flow point of glazes.
Painting enhancement
TSP is still in common use for the cleaning, degreasing, and deglossing of walls prior to painting. TSP breaks the gloss of oil-based paints and opens the pores of latex-based paint, providing a surface better suited for the adhesion of the subsequent layer.[10][unreliable source?]
Food additive
Sodium phosphates including monosodium phosphate, disodium phosphate, and trisodium phosphate are approved as food additives in the EU. They are commonly used as acidity regulators and have the collective E number E339.[11] The United States Food and Drug Administration lists sodium phosphates as generally recognized as safe.
