Now we use silicone products in many places in our life. For example, silicone kitchen utensils are more common. However, you must not know that there are many other types of silicone products besides silicone kitchen utensils, such as some food-grade and medical-grade silicone products. The following is Take everyone to understand what silicone products are available and what are their uses.
Silicone material can be divided into common grade, food grade, medical grade and special silicone. Food-grade silica gel is non-toxic, tasteless, insoluble in water and any solvent, and is a highly active green product.
Organic silica gel is mainly used in aviation, cutting-edge technology, special materials in military technical departments and construction, electrical and electronic, automobile, machinery, chemical light industry, medicine, etc.; inorganic silica gel is mainly used in desiccant, catalyst carrier, matting agent, toothpaste Abrasive etc.
The toughness and elasticity of silicone products are very good, they will not be deformed by external force, and they are non-toxic, odorless and colorless, and have no harm to the human body.
Simple analysis of the uses of silicone products:
1. Used for baby products, mother and baby products, baby feeding bottles, feeding bottle protective sleeves;
2. Used in the production of kitchen products, kitchen utensils and related auxiliary kitchen utensils;
3. Used for beauty accessories and daily necessities, such as silicone watch straps, silicone brackets, silicone bracelets, etc.;
4. Used for conductive silica gel, medical silica gel, foam silica gel, molding silica gel, etc.;
5. Used for silicone pads, silicone plugs and seals;
6. Used in copiers, keyboards, electronic dictionaries, remote controls, toys, and silicone buttons;
7. Used for gaskets, packaging materials for electronic accessories, and automotive electronic accessories.
8. Special materials and constructions for aviation, cutting-edge technology, and military technology sectors.
The main series of silicone products are as follows:
1) Maternal and baby series: including silicone spoons, silicone bowls, silicone dinner plates, silicone teethers, silicone pacifiers, silicone food supplement bottles, silicone bibs, etc.
2) Outdoor sports series: including folding water cups, retractable water bottles, sports bracelets, sports watches, silicone shoe covers, etc.
3) Beauty series: including facial cleansing brush, facial cleanser, makeup brush cleaning pad, manicure pad, makeup mirror, silicone powder puff, etc.
4) Kitchen series: including cutting boards, cleaning gloves, heat insulation mats, non-slip mats, coasters, drain racks, vegetable baskets, dishwashing brushes, scrapers, spatulas, silicone fresh-keeping covers, cake molds, cake cups, boiled eggs utensils, silicone seasoning bowls, etc.
5) Daily household series: including night lights, tea infusers, ice trays, ashtrays, wine corks, acupoint pads, bath brushes, silicone brushes, silicone key chains, placemats, etc.
Some main production methods of silicone products:
1. Molding: It is a silicone rubber processing method that molds silicone rubber raw materials into finished products by heating and pressurizing in a closed mold cavity. Usually, the powder sheet-shaped rubber block is first made into a blank similar to the finished product, placed in the cavity of a heated mold, and then closed and pressurized to form and solidify or vulcanize, and then demoulded to obtain Finished products, suitable for molding and processing of thermosetting products.
Molded products include: silicone rubber miscellaneous parts, bracelets, mobile phone cases, cake dispensers, LED lamp plugs, etc.
Advantages: 1. Can be made into any shape; 2. High precision, regular and beautiful product shape.
Disadvantages: 1. Can only be made with a length less than 600mm; 2. Many burrs and waste products will be produced; 3. The cost of the mold is expensive, the development cycle is long, and the output is low.
2. Dip coating: After the silicone rubber is liquefied, the product surface is wrapped with silicone rubber material by spraying or dip coating.
Dip coating products include: high temperature wire, glass fiber tube, finger cot, etc.
Disadvantages: 1. It can only be used for painting with the same color, and it cannot be registered; 2. The thickness of the coating film on the upper and lower parts of the object to be coated is uneven; 3. The solvent is volatile; 4. It is easy to pollute the environment; 5. The loss rate of the paint Also larger.
3. Calendering: The product has a regular thickness and an infinite length through the extrusion molding process of the numerical control roller distance equipment.
Calendered products include: silicone rubber coils, table mats, coasters, window grilles, etc.
4. Injection: Silicone rubber material is injected into the mold through liquid or solid. The product can be the same as compression molding, but the properties of the product are different.
Injection products include: medical accessories, baby products, milk bottle nipples, auto parts, toy accessories, etc.
There are many kinds of silicone products, and their functions are also different, but the main thing is to facilitate our life and bring convenience to our life.
