Density and safety of Silicone Mat
The density of Silicone Mat
Transparent or milky white granular solids. With open porous structure and strong adsorption, can adsorption various material. Such as absorption of moisture, moisture absorption quantity is approximately 40%, such as adding cobalt chloride, it is blue, while dry red after suction. Renewable repeated use.
Safety performance of Silicone Mat
Silicone Mat main composition is sio2, stable chemical properties, don't burn. Office supplies of silicone rubber pad is a kind of amorphous silicon dioxide, should control the workshop dust content is not more than 10 mg/m3, need to be reinforced platoon wind, when wearing a mask.
Silicone Mat has very strong adsorption capacity, drying effect on a person's skin, therefore, should be dressed in the uniform operation. If the Silicone Mat into eyes, need a lot of water flushing, and find a doctor as soon as possible.
It is pointed out that the blue Silicone Mat is toxic, because it contains a small amount of cobalt chloride, and should avoid contact with food and inhalation. If poisoning occurs, the doctor should seek medical treatment immediately.
When the Silicone Mat is used, the adsorption capacity of the water vapor or other organic substances in the medium can be reduced, which can be reused after recycling.
Why do manufacturers all emphasize that the product is made of silicone mat? How can you tell the difference between a real Silicone Mat? A few tricks of the industry to distinguish the true and false silicon rubber.
1. The brand must be certified by the relevant departments of the state
Food-grade silicone mat is made from silicate polycondensation of inorganic polymer gel material, its content is over 98%, avirulent insipidity, stable chemical performance, under the normal except hydrofluoric acid and caustic, not any response from the acid and alkali salt. Currently on the market infant products involves the Silicone Mat material, are divided into baby Silicone Mat products and food grade Silicone Mat, higher standard of baby Silicone Mat products, are required to pass through the state food and drug administration (fda) certification.
2. Latex, rubber fish eyes mixed to teach you three ways to identify
Due to consumption of silica gel pad is after refining and sterilization, can be directly when mixed with the food and drug according to the requirement and guarantees the drying of food and food to eat together, and on the human body without any side effects. Therefore, pay attention to the entrance security parents have towards the Silicone Mat materials infant products, kele silicone rubber is pointed out that at present there are a lot of baby products in latex, rubber as the phenomenon of Silicone Mat, even in the industry to carefully distinguish to distinguish true and false. Professionals generally choose the following three:
The first: test elasticity: rubber, latex elasticity is better, the silicone cushion is more fragile, when choosing, can try the flexibility first, if the elasticity is very good, it is likely to be rubber;
Second: see color: rubber, latex for impurity content more, can't be a transparent color products, office supplies and rubber is colorless, transparent, to do the transparent silicone rubber products must be with silica gel pad material
Third: smell: rubber, latex products, flavor is thick, smell smell smell, some manufacturers in order to cover up the taste and increase the fragrance, so choose the Silicone Mat material raw material would be much better.
Finally, the Silicone Mat is not very cheap because the process itself is more complicated, so don't buy cheap Silicone Mat when you buy.
Because the rubber contains the chlorination, it will react with oxygen in the air, and it will become slightly white.
Rubber is a flexible polymer. Rubber can be extracted from some plants trees juice, also can be artificial, both have quite a number of applications and products, such as tires, gasket, rubber, office supplies, etc., hence become an important economic crop. The cultivation of rubber is mainly concentrated in southeast Asia, such as Thailand, Malaysia and Indonesia.
Rubber is divided into natural rubber and synthetic rubber. It is divided into block, latex, liquid rubber and powder rubber. Latex is a rubber colloidal water bulk; The liquid rubber is a low polymer of rubber, which is usually a viscous liquid before vulcanization. Powder rubber is used to make the latex into powder, which can be used for ingredients and processing. In the 1960s, thermoplastic rubber was developed without chemical vulcanization. The rubber is divided into general and special types according to the use of rubber. It's an insulator, and it's not easy to conduct electricity, but it's possible to turn into a conductor if you have water or a different temperature. Conduction is the conduction of electrons in the molecules or ions of the substance.
