Micronized Silica (SS-SIL)
01 Manufacturing process
Silica hydrogel as a raw material of SS-SIL is composed by following mixing reaction between strictly selected sodium silicate and sulfuric acid.
Na₂Oㆍ3.4SiO₂ + H2SO₄ → Na₂SO₄ + 3.4SiO₂
Once silica gel manufactured by above reaction follows washing and drying process to get desirable physical properties. Next by grinding it, make a variety of SS-SIL grades with controlling particle size and shape, coherence among particles and filling structure of particles. The applications of SS-SIL are not only film, paint, ink, paper industries but also tooth paste, medicine, food industries because it's not harmful to human body.
02 Matting agent for paint, ink
Advantage of SS-SIL for paint industry
We are producing various grades of SS-SIL as a matting agent and ceaselessly developing new products to satisfy customer's desire.
03 Anti-blocking and processing aids for PLASTIC
Advantage of SS-SIL in plastic
The properties of Micronized Silica as an anti-blocking agent are maintaining transparency with the same refractive index of film and not being condensed between silica in film. Selecting anti-blocking agent for plastic film is very important because it has great effect on manufacturing condition and quality level of the film.
04 Processing aid for PAPER
SS-SIL as a filler or processing aids for papers is available in grades with different
properties in the following recording papers
Thermosensitive recording paper is widely used in facsimile machines, printers and labels due to its high reliability,
simplicity and high speed. Thermosensitive paper consists of a thermosensitive coloring layer coated onto a base
paper to a thickness of several microns. This layer develops a color when it is heated by a thermal head or a thermal
pen, and thus permits recordings to be made. Mixing SS-SIL with thermal colorants offers the following advantages.
1. A pure white thermosensitive paper is obtained and there is no soiling of the undercoat
2. Smudge adhesion and sticking are effectively prevented.
3. Excellent coloring properties are obtained.
05 Other applications
Filtering agentSS-SIL has great influence on manufacturing pure drink by filtering protein in it. SS-SIL is not harmful to human body because it is highly refined and has excellent adsorptive powder owing to plenty of minute pores strictly controlled. By controlling moisture contents it prevents dusts on working.
Moisture remover/ coagulation preventerIf moisture exists in zinc paint for or alumina paint, hydrogen gas occurs and it makes crack. Micronized powder makes heterogeneous color distribution owing to moisture during storage, transport and handling. SS-SIL has great adsorptive powder thus when added to power-type products, moisture is easily removed. Also it's not harmful to human body, SS-SIL makes it possible to take food custody for a long time when used as a food additive. Application : instant food, powder-type food (salt, sugar), animal food.
Powder additivesSS-SIL can store liquid additive, perfume or effective component because it's not harmful, has lots of minute pores and microscopic particle size. Also these components can be changed to powder-type and quantitative input is easily controlled Application : tooth pastes, medicines, foods, chemicals, etc.
DentifriceSS-SIL is used as functional material tooth paste because it's high purity micronized powder which is chemically stable. Comparing to normal precipitation silica it has high purity and low bulk density thus additive efficiency is excellent
