What are the comprehensive performance advantages of sodium hexametaphosphate as an additive for textile printing and dyeing?

　　There are many auxiliaries for textile printing and dyeing, but if you want to upgrade textiles to a higher level, you need to use the right additives; sodium hexametaphosphate, as one of the important raw materials for textile printing and dyeing, can be used to improve the quality of textile printing and dyeing, thereby improving the added value of textiles. Today, let's talk about the comprehensive performance advantages of sodium hexametaphosphate as an auxiliary for textile printing and dyeing?

　　

　　One. As a water softener, so that the fuel, soap does not precipitate, does not clump

　　The PH value of sodium hexametaphosphate is close to neutral, and it can form a complex with calcium ions in hard water, thus achieving the purpose of soft water. Sodium hexametaphosphate is used as a water softener and can be re-dissolved from the precipitate of insoluble calcium soap, magnesium soap or magnesium fuel that has been generated

　　In other words, the introduction of sodium hexametaphosphate in the solution can regenerate sodium soap, and even when the calcium soap or magnesium soap that has been formed, the clot of the calcium soap or magnesium soap will disappear. Similarly, sodium hexametaphosphate can regenerate fuels.

　　Two. Prevent sodium alginate from precipitation in contact with calcium

　　Sodium alginate syrup is the most suitable slurry for active fuels, but care should be taken to prevent sodium alginate from infiltrating into the calcium of hard water during manufacturing to generate calcium alginate.

　　Therefore, sodium hexametaphosphate must be added to prevent the formation of calcium alginate. In the normal state, the dosage of 5-10 g / l is enough, in special cases can be increased to 15-20 g / l, it can be added when modulating the printing paste, or it can be added when modulating the original paste.

　　Three. As a cooking aid

　　Nylon strand (polyamide fiber) in the dyeing before the treatment of soap, soda ash cooking, the addition of sodium hexametaphosphate (about 0.3% of the weight of the silk) can make the soap not be consumed by hard water, improve the cooking effect.

　　Four. Treatment of recycled water

　　In recycled water, due to the addition of sodium hexametaphosphate, the hardness is reduced, and it is not easy to produce calcium carbonate precipitate, avoiding blockage of the water pipe. The dosage is about two parts per million.

　　Five. Treat boiler water

　　Sodium hexametaphosphate can also be used for hard water treatment in the furnace, which can not only avoid the generation of pot scale, but also make the generated pot scale re-dissolve, but the price is higher than that of trisodium phosphate.

　　Six. Ingredients for synthetic detergents

　　Sodium hexametaphosphate is an important ingredient in synthetic detergents (e.g., sodium alkylsulfonate, sodium alkylbenzenesulfonate) because it has good water softening capacity and washing aid.

　　Textile printing and dyeing auxiliaries belong to the development of business-oriented industries, while vigorously doing a good job in the development of new products and new technologies, it is also necessary to spend greater efforts to study the application technology of products and provide comprehensive technical services and technical support. The comprehensive advantages of sodium hexametaphosphate can reduce the investment in fixed assets, avoid continuous large-scale production, use intermittent production, be close to the market, and produce on demand to avoid unnecessary losses.
