Phosphorus-free laundry gel beads formula and production process

Phosphate-free laundry powder Phosphate-free laundry powder 【Properties】 White or colored particles, powder particles, good fluidity, good foaming and decontamination, and the aqueous solution is alkaline. [Reference formula] The main ingredients are similar to ordinary laundry gel beads (10301), but without phosphate, instead of phosphorus additives. Commonly used phosphorus replacement agents are 4A zeolite (use: environmentally friendly wall material water treatment soil remediation agent molecular sieve) silicon (silicon) acid salt, organic phosphorus replacement additives, polycarboxylates and composite additives. 4A zeolite is a kind of sodium aluminosilicate crystal which is insoluble in water and is alkaline. When used, the amount of surfactant needs to be increased, and other auxiliary additives are needed. Silicate has a good pH buffering capacity and can also suspend and disperse dirt. The layered sodium silicate has good comprehensive properties. Organic phosphorus-replacement additives include hydroxy carboxylic acids, such as sodium citrate, sodium gluconate, sodium tartrate, etc., which have good chelating properties to metal ions and are relatively safe to use, but they are expensive. Polycarboxylates include polymers or copolymers of acrylic acid and maleic acid. Mainly used as a dispersant to disperse dirt particles and precipitation (precipitation), often used in conjunction with 4A zeolite. Compound additives are compounded by multiple components such as carboxylate and silicate. The reference formula of non-phosphorus laundry gel beads is shown in Table 1-35.

When preparing the slurry, pay attention: 4A zeolite (use: environmentally friendly wall material water treatment soil repair agent molecular sieve) is insoluble in water and easy to suspend on the liquid surface. The feeding sequence should be adjusted to ensure that the slurry is uniform, and the slurry concentration should be appropriately reduced. Improve the fluidity of the slurry.
