Properties and application of silica gel
Silica gel is a kind of highly active adsorption material, which belongs to amorphous material, and its chemical formula is mSiO2-nH2O. Insoluble in water and any solvent, non-toxic and tasteless, stable chemical property, except alkali, hydrofluoric acid, and not with any of the material reaction. Various types of silicone because of its manufacturing method is different and the formation of different pore structures, silica gel chemical components and physical structure determines the it has characteristics of many other similar materials to replace: the adsorption of high performance, good thermal stability, chemical stability, high mechanical strength etc..
According to the pore size of silica gel is divided into: macroporous silica gel, porous silica, silica gel, silica gel pore type B. Because of the difference of the pore structure, the adsorption performance of the structure is different. Coarse pore silica gel under high relative humidity has a higher adsorption capacity; gel pore is under low relative humidity adsorption capacity is higher than that of the coarse pore silica gel, and type B silica gel due to the pore structure between coarse and fine pored silica gel. The adsorption capacity in between the coarse and fine pores. Macroporous silica gel is generally used as catalyst support, and the extinction agent, toothpaste, etc.. So we should choose different varieties according to different uses.
Application scope of Silicone Printing products not to take off. Can Taose, break through the silica gel printing a single color, color monotonous, rarely used for the bottleneck of the fashion field, provides a promising decoration materials to the fashion industry. Silk screen after the pattern has a strong sense of three-dimensional, and feel soft. Silk screen printing pattern has excellent peel strength, wear resistance, light intensity, water washing fastness.
Silk screen printing is a kind of special silica gel which can be firmly adhered to the surface of the textile by screen printing. Very high, Baoduo Paul / silicon Taiwan for health.
Use: used in various categories of products, non slip waterproof, high temperature, care and decoration etc..
Screen printing silicone product features:
1: environmental protection. Strong sense of color printing and weaving angle decorative bottle memo
2: color printing. When printing off layer chromatography.
3: can print a variety of effects. Light / matte, right angle / corner.
Environmental protection textiles, silicone, with good adhesion, high strength, soft and delicate feel, strong sense of three-dimensional, decorative effect, excellent performance, non-toxic harmless, etc..
Silica gel after absorption of water, can be regenerated by exposure, baking, drying and other methods.
The main ingredients of silica gel are silica, chemically stable, non-toxic.
Silica gel has a strong adsorption capacity, the human skin can produce a dry effect, if silica gel into the eyes, need a lot of water washing, and seek medical treatment as soon as possible.
Blue silica gel due to the presence of a small amount of cobalt chloride, toxic, should avoid contact with food and food, such as the occurrence of poisoning should immediately seek medical treatment.
The use of silica gel has a strong adsorption can quickly and effectively absorb the moisture in the sealed package, the chemical properties of stability, non-toxic harmless characteristics. Coupled with continuously in recent years of innovation and development, all kinds of silicone rubber has been widely used in purification of drugs, electronics, senior cosmetics, sewage purification, purification of beer, advanced coatings and resin production or preservation of KNA separation, dry food, high precision, in our daily life and production and business activities, silica gel is often used for the following:
Precision optical instruments, electronic appliances dry mouldproof packaging.
Hand drying: if placed in leather leather, leather bag, leather shoes to play the role of drying quality;
Food drying: in on the biscuit and fried foods, to ensure food.
Drug drying: put in bottle, extend the storage period to ensure drug;
Dry container: container transportation in different latitude will formation box black, "rain" if you use silica gel desiccant, it can slashing is equal to its own weight in water, of ocean shipping for up to 50 days in the process, can effectively reduce dew point and the container of water condensation phenomenon under control.
With the item class hotel: if placed in the closet, and shoes under the bed, adsorption odor, dry and fresh air quality.
