Health problems are always the biggest hidden danger for human beings. As an expectant mother, the most important thing is to prepare daily necessities for the baby to be born next.Have you chosen all the baby products?What brand what material is the best, we should have heard of silicone teether, what is silicone made?Is it safer to use?

Silicone teether is made of food-grade silica gel, which does not contain bisphenol A, and will not break, tear strength, resilience, resistance to yellowing, heat aging and weather resistance.

Generally speaking, silica gel can be divided into organic silica gel and inorganic silica gel according to its properties and components

Inorganic silica gel

Inorganic silica gel is a kind of highly active adsorption material, which is usually prepared by the reaction of sodium silicate with sulfuric acid and a series of post-treatment processes such as aging and acid bubbles.Silica gel is an amorphous substance, and its chemical formula is mSiO2.NH2O.Insoluble in water and any solvent, non-toxic tasteless, chemical properties are stable, except strong base, hydrofluoric acid and no reaction with any substances.

Different types of silica gel have different microporous structures due to their different manufacturing methods.The chemical component and physical structure of silica gel determine that it has many other similar materials are difficult to replace the characteristics: high adsorption performance, thermal stability, chemical stability, has a high mechanical strength, etc., home used as desiccant, humidity regulator, deodorant, etc.Industry as oil hydrocarbon decolorization agent, catalyst carrier, variable pressure adsorbent;Fine chemical separation and purification agent, beer stabilizer, paint thickener, toothpaste friction agent, extinction agent.

Organic silicone

Silicone is a kind of organosilicon compound, is refers to contains the Si-C bond, and at least one organic group is directly connected with the silicon atoms of the compound, the custom is often those through oxygen, sulfur, nitrogen, etc.Among them, polysiloxane, which is composed of silicon oxygen bond (-si-o-si -) as the skeleton, is the most numerous, the most studied and the most widely used type of organosilicone compounds, accounting for more than 90% of the total dosage.

Organosilicon is mainly divided into four categories: silicone rubber, silicone resin, silicone oil and silane coupling agent.

The main component of silica gel is silica dioxide, which has stable chemical properties and does not burn.Silica gel is a kind of amorphous silicon dioxide, should be controlled workshop dust content no more than 10 mg/m3, need to strengthen the exhaust air, operation wear a mask.

Silica gel has a strong adsorption capacity, can produce dry effect on the skin of the person, therefore, operation should wear good work clothes.If the silicone enters the eye, rinse with plenty of water and see a doctor for treatment as soon as possible.

Blue silica gel contains a small amount of cobalt chloride, has potential toxicity, should avoid contact with food and inhalation in the mouth, such as poisoning incidents should immediately seek medical treatment.

Silica gel in the use of the process due to the adsorption of water vapor or other organic substances in the medium, adsorption capacity decreased, can be reused after regeneration.
