Colloidal Silver Nano Silver Solution CAS 7440-22-4

(Colloidal Silver Nano Silver Solution CAS 7440-22-4)

Overview of Nano Silver Colloid

Nanosilver solution is a metallic silver element with a 1-100nm particle size. The particle size of nanosilver is mostly about 20 nanometers, and a few can reach less than 5 nanometers. Approximately 650 species of bacteria have broad-spectrum bactericidal effects and will not develop drug resistance. Animal experiments show that even if the dose of nanosilver antibacterial powder reaches thousands of times the standard dose, the test animals show no toxicity. At the same time, it can also promote the repair of damaged epithelial cells. It is worth mentioning that the antibacterial effect of this product is increasingly enhanced when exposed to water, making it more conducive to treating diseases.

Silver nanoparticles act on cell membrane proteins and can directly destroy bacterial cell membranes and oxygen metabolism enzymes (-SH), preventing bacteria and other microorganisms from absorbing essential nutrients for growth, such as amino acids and uracil, thereby inhibiting their growth. This unique mechanism kills most bacteria, fungi, and other microorganisms. Silver nanoparticls have super permeability and can quickly penetrate 2mm under the skin for sterilization. They have a good sterilization effect on deep tissue infections caused by common, stubborn, and drug-resistant fungi.

Product Performance of Nano Silver Colloid

Nanosilver solution is a colorless and transparent liquid or light yellow, made from nanosilver with a particle size less than 2nm through nanotechnology.

Colloidal silver is widely used in various fabrics, including cotton, blended fabrics, chemical fibers, non-woven fabrics, leather, etc., for washing resistance and antibacterial purposes. After treatment, the textiles will not affect the origin, color or condition, and the antibacterial effect can remain above 99% even if washed 50 times.

Technical Parameter of Nano Silver Colloid

How is Nano Silver Colloid Produced?The invention relates to a preparation method of nanometer silver solution. The weight ratio of the main raw materials is AgNO3: reducing agent: gellan gum: auxiliary agent: surfactant = 0.8~1.2:0.8~0.5:0.5~1.8:1.8~2.2:2.8~3.2. Preparation steps: Prepare AgNO3 aqueous solution and reducing agent aqueous solution respectively; mix Gellan Gellan with NaCl or sugar according to the weight/part ratio of Gellan: NaCl/sugar = 1:9-11, and put it into the ultrasonic field to react with high shear dispersing emulsifier In the container, add water, heat to 50-70°C, rotate at 500-700 rpm/min, and stir to prepare mixed solution A. Add additives and continue stirring to mix. Dissolve the surfactant in hot water, add it to the reactor, continue stirring and mix at a speed of 500 to 700 rpm/min. Pump the aqueous solution of AgNO3 and reducing agent into the reactor, increase the rotation speed to 2000-3000 rpm/min, and prepare a nanosilver solution with a particle size of 3-60 nm by continuously stirring for 0.5-24 hours.

Applications of Nano Silver ColloidColloidal nanosilver can be used in medical and health care, medical equipment, textiles, paint, daily necessities, cosmetics, flowers, ecological environment, and other fields.1. Antibacterial finishing of textiles, paper products, leather and sponges;2. Antibacterial and deodorant treatment for all kinds of shoes, toys and daily necessities;3. It is suitable for antibacterial deodorization of various waterborne and oil-based coatings;4. Widely used in the medical field: fungicides, medical hose, colloidal silver, lotions, tablets; Soap, cleaning supplies; Chemical building materials; Plastic products;

5. Nano colloidal silver can be added to PE, PP, PC, PET, ABS and other plastics to achieve antibacterial function.

FAQ

Q1

What is nano colloidal silver used for?

Answer: Colloidal silver has been used for infections, hay fever, skin conditions, and many other conditions, but there is no good scientific evidence to support any of its uses. There is also no good evidence to support using colloidal silver for COVID-19. It can be unsafe when taken by mouth, applied to the skin, or inhaled.

Q2

What is nano silver solution?

Answer: Nanosilver is made up of silver nanoparticles. These particles serve as antibacterial and antifungal agents for industrial purposes, in water treatment, and in consumer products (such as clothing, cosmetics, childcare items, food containers, and many others).

Q3

Is nano silver safe for humans?

Answer: The toxicity of nano silver is closely related to the size of the particles. Most silver nanoparticles are toxic to the human body, and it is precisely because of their small particle size that they can penetrate human tissues.

Q4

What is the difference between colloidal and nano silver?

Answer: The difference is in the particles. Nano particles are much smaller and more easily absorbed and pass through the body much more quickly. Colloidal particles are larger and absorbs slower and lingers longer in the body.
