Ordinary laundry gel beads formula and production process

General laundry powder [Alternative name] Laundry powder [Properties] White hollow particles, free-flowing, low apparent density, good water solubility, the aqueous solution is weakly alkaline, and has good foaming and decontamination properties. [Reference formula] The main ingredients are surfactants, additives and other additives. The synthetic detergent for laundry gel bead processing is based on surfactants as the main component, and is equipped with a suitable amount of builders with different functions. Laundry gel beads refer to powdery (granular) synthetic detergents. The surfactant can be a single anionic surfactant, or a combination of anionic and nonionic surfactants. The use of compounding can not only improve the detergency of the laundry gel beads, but also reduce the amount of surfactants and reduce costs. Commonly used anionic surfactants are linear sodium alkyl benzene sulfonate (LAs), sodium alpha alkenyl sulfonate (AOS), sodium secondary alkyl sulfonate (SAS) and so on. Non-ionic surfactants often use fatty alcohol polyoxygen (Oxygen) vinyl ether (AEOg. AE07), commonly used additives are sodium tripolyphosphate, sodium carbon (C), sodium silicate, sulfuric acid (chemical formula: H2SO4) sodium and Zeolite etc. Sodium tripolyphosphate (STPP), commonly known as pentasodium, has excellent performance, but due to its serious environmental pollution, its use has been restricted or prohibited in some areas. Commonly used additives include flavors, brighteners, enzyme preparations, sodium p-toluenesulfonate, sodium carboxymethyl cellulose (CMC) and so on. The reference formula of ordinary laundry gel beads is shown in Table 1P23. Table 1-23 Reference formula of ordinary laundry gel beads Ingredient dosage/part Ingredient dosage/part Percarbonate Yellow (PC) 40.0 Sodium Carbonate 10.0 Sodium Sulfate 5.0 Sodium Tripolyphosphate (STPP) 15.0 LAS　　　　　　10 ．0　　　　　　　silicon sodium (silicon) 2.0～4.0 magnesium sulfate 0.5　　　　　　　　　　　tetraacetyl ethylene diamine (TAED) 4.0 [Preparation method] First, the alkylbenzene (chemical formula: C6H6) sulfonic acid and 30% The liquid caustic soda of the left and right concentration is neutralized in the mixing tank, and then other materials other than nonionic surfactants and flavors are added in a certain order according to the formula ratio. The main components of laundry gel beads are anionic surfactants, sodium alkylbenzene sulfonate, a small amount of non-ionic surfactants, plus some additives, phosphates, silicates, sodium sulfate, fluorescent agents, enzymes, etc. It is made by mixing, powder spraying and other processes, and now most of them use 4A fluorspar instead of phosphate. Laundry gel beads refer to powdery (granular) synthetic detergents. The order of feeding is generally the first to cast insoluble materials, the apparent density (unit: g/cm3 or kg/m3) is small, and the proportion in the formula is small; the latter is easy to dissolve, the apparent density is high, and the proportion in the formula is High material, in order to achieve the purpose of uniform slurry. The prepared slurry is filtered through a filter screen, continuous filter, or vacuum suction filter, and then degassed with a deaerator, and then subjected to a homogenizing pump or colloid grinding to obtain a more uniform and delicate slurry , Then use a high-pressure pump to drive it into the top of the spray drying tower, atomize it into fine droplets by the atomizer, and meet the high temperature airflow in the tower to instantly dehydrate and dry them into hollow particles. The powder discharged from the bottom of the tower is cooled, aged, and screened, and flavors are added to special equipment. Products that need to add non-ionic surfactants can be sprayed in while adding flavor, and then packaged. [Product standard] GB/T 13171-1997 [Use] Wash all kinds of fabrics.
