Silica as the main raw material processing
system works, called silicone products. Silicone is an appropriate dehydration
by the silicic acid gel particles of different sizes of a porous substance.
Having an open porous structure and can absorb many substances, it is a good
desiccant, an adsorbent and a catalyst carrier. Silica gel adsorption mainly
physical adsorption, can be regenerated and used repeatedly. The addition of
acid in the alkali metal silicate solution (such as sodium silicate),
acidified, and then a certain amount of electrolyte is added and stirred, which
generate silicic acid gel; adding acid or sodium silicate solution in a darker
or The ammonium salt can also generate silicic acid gel. Silicic acid gel was
allowed to stand for several hours so that aging, and then wash with hot water
soluble salts, and dried at 60 ~ 70 ℃ and activation can be obtained at about 300 ℃ silica. Silicate gel with cobalt chloride
solution soaking and then drying and activation available silica gel.
Silicone rubber is a highly active
adsorption material is amorphous material, its chemical formula is mSiO2 •
nH2O. Insoluble in water and any solvent, non-toxic, tasteless, chemically
stable, in addition to alkali, hydrofluoric acid does not react with any
substance. Various types of silica because of their different manufacturing
methods and the formation of different pore structure. The silicone chemical
components and physical structure, it difficult to replace many other similar
material characteristics: high adsorption properties, good thermal stability,
chemical stability, high mechanical strength.
Food grade silicone with non-toxic,
tasteless, insoluble in water and any solvent, the product of a highly active
green food grade silicone with inherent thermal stability (-40 ℃ -230 ℃). Suitable for different occasions. The product has good
flexibility to meet different needs.
Characteristics of silicone products:
High temperature: Suitable temperature
range -40 to 230 degrees Celsius, and can be used in the microwave and oven.
Easy to clean: silicone products with silica
production can resume rinse clean dishwasher.
Long life: the chemical properties of the
silica material is very stable, the system to make the product, have a longer
life compared with the other materials.
Soft and comfortable: thanks to the
softness of silicone material, the Cake Mold products feel comfortable, highly
flexible, no deformation.
Diverse colors: according to customer
needs, the deployment of different beautiful colors.
Environmental non-toxic: not produce any
toxic or hazardous substances from raw materials to finished products shipped.
Electrical insulating properties are:
silicone rubber having a high resistivity, and in a very wide temperature range
and within the frequency range of its resistance can remain stable. Silicone
voltage corona discharge and arc discharge with good resistance, such as
high-voltage insulators, TV high hat, electrical parts.
Low temperature resistance: rubber lowest
use temperature critical point of -20 degrees to -30 degrees, silicone rubber,
however, still has good flexibility at -60 degrees to -70 degrees, some
specially formulated silicone rubber also bear very low temperature, such as
low temperature seals.
Conductivity: When adding conductive
fillers (such as carbon black), silicone rubber, it has good electrical
conductivity properties, such as keyboard conductive contact points, electric
component parts, antistatic components, high voltage cable shielding the
medical treatments conductive film, etc..
Weathering resistance: ordinary rubber to
degrade rapidly in the ozone generated by corona discharge under the action of
silicone rubber against ozone impact, and in the ultraviolet radiation and
other climatic conditions for a long time, its physical properties also only
small changes, such as outdoor use sealing materials.
Thermal conductivity: When add some heat
conductive filler, the silicone rubber having a good thermal conductivity, such
as heat sink, a thermally conductive gasket, copiers, fax machines, thermal
roller or the like.
Resistance to radiation: the
radiation-resistant silicone rubber containing phenyl greatly improved,
insulated cables, such as electricity, nuclear power plants with the connector.
Silicone products:
Silicone products can be divided
into three categories, depending on the molding process lines:
Molded silicone products
Molded silicone products usually put
pressure on Add to add the the vulcanizing agent's solid silicone raw materials
by high temperature mold vulcanizing machine, high temperature sulfur
solidification molding molded silicone hardness is usually in the 30 ° C-70 ° C Raw materials with creams adjusted
according to the Pantone swatch color, the shape of the mold determines the
shape of the molded silicone products, molded silicone products are the current
silicone industry in the use of the most widely used one. Only silicone is
mainly used for industrial parts, buttons, silicone gifts, silicone wristband,
silicone watches, key cases, mobile phone sets, silicone kitchenware, silicone
mat, Ice Cube, Cake, etc..
Extruded silicone products
Extruded silicone products usually through
extrusion machine extruded silicone molding, general extruded silicone shape is
long, tubular can easily cut, but the shape of the extruded silicone
limitations in medical equipment, food machinery in a wide range to use.
Liquid silicone products
Liquid silicone products silicone injection
molding injection molding, the product is soft, the hardness can reach 10 °
C-40 ° C, in emulation of human organs and the medical Guijiaoxiongdian, and
other widely used because of its soft characteristics.
There are also specialty silicone products:
specialty silicone products based on the chemical properties of silicone or add
auxiliary materials, specialty silicone products can also have a high
temperature (up to 330 degrees), food grade (fully comply with U.S. FDA, FLGB
Standard) , medical grade, flame retardant grade, by adding auxiliary materials
can also have a luminous, negative ions, color, and other characteristics.
The use of silicone products:
Silicone products production copiers, keyboard,
electronic dictionary, remote control toys, condoms, silicone buttons
indispensable part.
Can be used to make durable shaped molding
gaskets, electronic accessories packaging materials, automotive accessories,
maintenance materials.
Can be used to make electronic components,
molded high point edge sub.
Can be used for the production conductive
silicone, medical silicone, foam silicone, molding silicone.
For housing construction and repair of,
seam sealed highways, bridges, sealing sealing project.
Superior performance, coupled with silicone non-oil products, does not
rely on increasingly scarce oil resources, makes silicone products to become
the alternative to similar plastic products, silicone products can be applied
to a lot of use of plastic can not do field such as baby pacifiers, human
organs such as application prospects are very bright. All our silicone products
approved by FDA, SGS certification and European LFGB certification. Exported to
the United States, Britain, Germany, Russia, the Netherlands, Spain, Australia,
Denmark, Italy, Hungary, Switzerland, Sweden, Hong Kong and other countries and
regions, and consumers get the universal recognition and praise. I believe that
in the near future, the silicone household will become the beautiful landscape
of people's lifestyle.
