Factors affecting the quality of Silicone Mat
Silicone Mat is one of the most popular products and is one of the most popular cooking utensils. Silicone Mats are long life, mildew proof, easy to clean, high and low temperature, and automatic sterilization. Compared with traditional kitchen utensils and appliances, it is more suitable for people's demand for kitchenware products now. It brings more convenience to life, and the factors affecting the quality of silicone cushion are mainly the following.
The volume characteristics of a liquid, a liquid, or a liquid that is intended to resist the flow of a solid, that is, the internal friction or internal resistance that is present in the molecules when they are being moved by external forces. Usually the viscosity is proportional to the hardness.
The ability of a material to resist hard material in its surface is called hardness. The Silicone Mat has a range of 10 to 80, which gives the designer the freedom to choose the hardness required to achieve a particular function. A variety of intermediate hardness values can be achieved by mixing polymer base materials, filling materials and auxiliaries. Likewise, the time and temperature of curing the solidification can also change the hardness without breaking other physical characteristics.
3. Tensile strength.
Tensile strength refers to the force required for each range unit when a sample of rubber material is torn. The tensile strength range of hot and sulfur solid silicone cushion is between 4.0-12.5mpa. The tensile strength range of fluorosilicone cushion is between 8.7 and 12.1 MPa. The tensile strength of liquid Silicone Mat is between 3.6 and 11.0 MPa.
4. Tear strength.
The resistance to an incision or indentation is prevented by applying force on a sample with an incision. Even after being cut open and placed under extreme torsional stress, hot and sulphur solid Silicone Mats can not be torn apart. The tear strength range of hot and sulfur solid silica gel is between 9 and 55 kN/m. The tear strength range of fluoro silicone cushion is between 17.5-46.4 kN/m. The tear strength range of liquid Silicone Mat is between 11.5 and 52 kN/m.
Usually refers to the percentage of "breaking elongation" or the percentage of the sample that is relative to the original length when the sample breaks. The extended range of hot and sulfur solid Silicone Mats is between 90 and 1120%. The elongation rate of fluoroSilicone Mats is between 159 and 699%. The normal elongation of liquid Silicone Mat is between 220 and 900%. The different processing methods and the selection of hardener can change the elongation greatly. The elongation of the Silicone Mat has a lot to do with temperature.
6. Operation time.
The operation time starts from the moment the gel is added to the vulcanizer. Behind the operation time and the boundaries of the curing time is not fully, the colloid from join the vulcanizing agent that moment start already for curing reaction, the operating time is the product of 30 minutes vulcanization reaction can not affect the quality of the finished product. So the more you save time in the process, the better the product will be.
7. Vulcanization time.
Some places will say curing time. That is to say, the sulfide reaction of the silica gel over such a long period of time is basically over. This basically ends up saying that the product is already available, but there's actually a very small amount of solidification that's not done. So, products made with Silicone Mats, such as silicone molds, are usually put in use for some time.
Silicone Mat is non-toxic and tasteless, with automatic sterilization function, high temperature resistance, convenient cleaning, easy to use, saving effort, and time saving. The structure is fine, the color is varied, can choose the color that oneself likes, is a family fashionable kitchen utensil.
