Classification and advantages and disadvantages of silicone board, the difference between silicone b

Depu Technology (Shenzhen).

Silicone board can be divided into two types according to specifications: G-type H-type GF254 HF254 and other types are divided into ordinary board and high-efficiency board! According to the molding process, it is mainly divided into two types.

1. Extrude the silicone board.

Extruded silicone sheets are formed by an extrusion molding machine, and the extruded silicone sheets, like ribbons, can be circled together for several meters and can be freely cut to length.

Advantages: fast maneuverability, low cost, high output, fast production speed, free cutting length, uniform thickness.

Disadvantages: In the later stage, the die needs to be matched in order to cut out a specific shape.

2. Molded silicone board.

Molded silicone sheet is a fixed size silicone sheet formed by high temperature vulcanization through a silicone mold, and the silicone board has a limited area and a fixed length and width.

Advantages: stable production, good quality of raw materials, good color, hardness, good control of raw material grade, consistent size.

Disadvantages: The output is low, the cost is 2-3 times that of the extruded silicone board, and the thickness is uneven.

Silica gel sheets can be used directly for the rapid separation of many types of organic substances—qualitatively or quantitatively. It has been widely used in the identification of trace impurities and main components of medicine, pesticides, Chinese herbal medicines, organic spring oak chemical products and grains and foods. The full name of silica gel plate is thin layer chromatography silica gel plate, which is sprayed with high-purity thin layer chromatography silica gel into a certain amount of binder.

Pasta is a common staple food in many parts of China, and the board is used to make noodles, and many people will think about whether to buy a silicon bucket rubber board or a wooden board. PCHOUSE will introduce you to the difference between silicone panels and wooden boards today.

1. Differences in raw materials.

Silicone panels are mostly made of food-grade silicone, the chemical composition is relatively stable, and the ones that meet the FDA food-grade certification are relatively safe and environmentally friendly, and can directly contact the human body. There are no toxic substances or gases during daily use, so there is no need to worry about using it even in the presence of high temperatures. The wood board mainly chooses birch and willow, and generally does not choose wood with taste, such as black cypress, which contains peculiar smell and toxic substances.

2. Easy to clean.

The silicone panel is not afraid of water, and can be washed directly after use, and if it is stained with oil, it can also be cleaned with a neutral detergent, and it will be fine after drying. However, it is more difficult to clean the wooden board, if it is not disinfected, and the environment is relatively humid, it is very easy to grow mold spots and contaminate food.

3. Comfort of use.

Wooden board is our commonly used material, it is generally thicker, it will be more stable when cutting things and kneading hard dough, and the silicone panel is soft and thin, if you often cut things on the surface, there will be a difference in the front shirt will be damaged.

There are many advantages of silicone products, but there are also many disadvantages!

Advantages: environmentally friendly and non-toxic, compared with other materials, silicone material has better performance, can be adapted to various occasions, has a wide range of use, furniture, automobiles, manufacturing, machinery, medical, and other industries have applications, known as environmental protection iconic material products.

Disadvantages: **Expensive, complex production methods, difficult to make large sizes, single style, ordinary silicone jewelry is easy to stick to dust, etc.!

It can be used directly for the rapid separation of many types of organic substances - qualitative or quantitative analysis.

It has been widely used in the identification of trace impurities and main components of medicine, pesticides, Chinese herbal medicines, organic chemical products, grains and foods.

Peculiarity. 1. The separation effect is good, and the number of plates is high.

2. The spotting spots are small, which is convenient for series analysis.

3. Short separation time.

4. High sensitivity, clear spots, non-spreading.

Brief introduction. Product name: Silicone sheet, a noun in the chemical industry"Silicone sheets"Just a short abbreviation, its full name should be called thin layer chromatography silica gel plate, also called high tear silicone board, it is made of high-purity thin layer chromatography silica gel (powder) mixed with a certain amount of binder spray, its plate surface is generally glass, and it is more popular abroad to use aluminum foil to do the attached plate surface.

Silicone rubber sheet is a very special material, which is widely used, which involves the construction industry. Therefore, it is used in the construction of houses and when renovating houses. So, what kind of profile is silicone rubber sheet?

What kind of profile is the silicone rubber sheet.

Silicone rubber sheet is actually made of silicone rubber, and silicone rubber can be divided into two categories: organic silicone and inorganic silicone. Inorganic silica gel is a highly active adsorption material, which is made by reacting with sodium silicate and sulfuric acid, and finally made after a series of treatments such as aging and acid foaming.

Silica gel is also an amorphous substance, the chemical formula is that it is insoluble in water and other solvents, non-toxic and tasteless, and will not react with any substance other than strong alkali and hydrofluoric acid. It is also widely used, can be used as a special material in aviation, cutting-edge technology, military technology departments, and can also be used in construction, electronic and electrical, textile, automobile, machinery, leather and paper, chemical light industry, metal and paint, medicine and medical treatment.

What are the characteristics and uses of silicone rubber.

1.Product features: It has good insulation performance, aging resistance, sealing performance, and good adhesion and high strength, it is a non-corrosive one-component room temperature vulcanized silicone rubber, in the temperature range of -50 to +250, long-term use will not have any problems.

2.Product use: The main uses of silicone rubber are insulation, moisture-proof, sealing, bonding, anti-vibration, etc., such as bonding and sealing materials for semiconductor equipment, electronic appliances and other equipment; There are also sealing materials for related parts of aircraft cockpits, instrument compartments, and machine building.

This material is also an ideal material for elastic adhesives such as aviation, electronics, and electrical appliance manufacturing.

3.Instructions for product use.

a.The surface of the product needs to be cleaned first, and the rust, dust, and oil stains adhered to the rotten tomb should be cleaned first;

b.After that, the glue is applied, the hose is unscrewed, the plastic nozzle is installed, and then the required size is opened with a blade, so that it is easy to squeeze the glue to the required position;

c.After use, the next step is to wait for curing, then put the coated part in a stable position and wait for curing. The curing is from the outside to the inside, the depth of glue curing is 2-4mm, that needs to be cured within 24 hours, the humidity will be 55% will be cured, if the depth exceeds this depth, the time will be extended, if the humidity is relatively low, the curing time will be extended.
