Water softening ion exchange performance features: 4A molecular sieve framework are each oxygen atom is shared by two adjacent tetrahedra, this structure which may be occupied by cations and water molecules large bugholes, and these cations and water molecules have a greater mobility, cation exchange and reversible dehydration. 4A zeolite is ion exchange with aluminum ions in the framework carried a negative charge carried by each of the aluminum ions, may be not only sodium ions, may also be combined with other cations. Calcium and magnesium ions can enter the original sodium ions occupy a large crystal cave, the 4A Zeolite replace sodium ions 4A Zeolite down ---- that sodium ions can be exchanged with hard water Ca2 + ,, Mg2 + ions exchange, so as to achieve the purpose to soften water.
Combined with calcium and magnesium ions in zeolite 4A speed slower than sodium tripolyphosphate, and with the ability to bind magnesium ions is weak. But 4A molecular sieve can be a small amount of water in harmful heavy metal ions (such as Pb2 +, Cd2 +, Hg2 +) can be very easily and quickly removed to purify water has very important significance.
---- Carrier liquid of adsorptive functional surfactant: As 4a molecular sieve crystals of the hole structures, plus fine particles having a large specific surface area, so the strong adsorption performance of 4A molecular sieve.
Adsorption of non-ionic surfactants, 4a molecular sieve 3 times NTA (nitrilo-triacetate) and sodium carbonate, five times the sodium tripolyphosphate (STPP) and sodium sulfate, and the nature of the molding for the agglomeration production of high-concentrated detergent formulated with more surfactants, washing and flow properties obtained good product makes sense. Through the experiment, liquid Zeolite 4A carrying capacity ≥30%, 4A molecular sieves in the detergent production process, increase the mobility of the material, to adjust the viscosity, obtained product appearance, sexual fluidity and anti-caking good product.
Detergency: experiments with different additives on the same formula, changing its detergency aid comparison, found 20% of the STPP, 20% of the molecular sieve, 4% polymer and 40% of the decontamination effect STPP rather, in 20% of non-phosphorus zeolite added 10% sodium carbonate and 4.5% of the polymer obtained very good detergency products.
Redeposition properties: 4a molecular sieve with good adhesion of oil, when sodium carbonate, CMC, sodium silicate and sodium and other additives added zeolite adsorption decreased nylon fabric for oil pollution. Particle size of the zeolite at 0.4-1.0μm, better dispersibility can be prevented from adhering on the fabric.
Although not as good as 4A molecular sieve dispersing ability STPP, but with sodium polyacrylate dispersion can solve complex problems of dirt.
Compatibility with other additives: 4A Zeolite proper performance and other additives can make it complementary, 4A molecular sieve dirt dispersion and hardness ions chelating inferior STPP, but 4A Zeolite mix with STPP, detergency can STPP reached with a single effect. This is because since the solid surface can quickly STPP complex calcium and magnesium ions, and passed through an aqueous medium 4A molecular sieves. 4A Zeolite magnesium ion binding ability, can be obtained by molecular sieve complex silicates, carbonates be compensated.
PH buffer: 4A molecular sieves alkaline PH 1% aqueous solution at 11.0, and therefore has a certain buffer alkalinity.
Safety: 4A Zeolite non-toxic, safe to human height. Eyes, skin irritation, does not cause allergies, safety and reliability. After washing deposited in the soil, does not cause pollution, but also can improve soil, 4A Zeolite no adverse impact on the ecology
