Industrial Silicon Nitride ceramic Si3n4 roller wheel caster
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Silicon Nitride Ceramics are heat-resistant to 65°C and cold-resistant to -20°C. They are only suitable for warm or frozen drinks. They are easily deformed when they are filled with high-temperature liquids or heated, and harmful substances are melted out. In addition, scientists discovered that after 10 months of use for No. 1 plastic, it may release the carcinogen DEHP, which is toxic to the testis. Therefore, throw away the beverage bottle when it is used up, and don't use it as a water cup, or as a storage container for other items, so as not to cause health problems. Note: Do not recycle beverage bottles for hot water. Don't put it in the car to bask in the sun; don't put alcohol, oil and other substances. It can be reused after careful cleaning, but these containers are usually not easy to clean. The original cleaning supplies remain and become a breeding ground for bacteria. You'd better not recycle them. Don't use it as a water cup or as a storage container for other items. Note: It is difficult to clean thoroughly, it is recommended not to recycle. Use: This material has excellent plasticity and low price, so it is very popular. It can only be heat resistant to 80 ℃, it is easy to produce harmful substances at high temperatures, and even release toxic substances during the manufacturing process. If it enters the body with food, it may cause breast cancer, birth defects and other diseases. Containers of this material have been less used for packaging food. If you use it, never let it get hot. Difficult to clean and easy to remain, do not recycle. Do not buy if it contains drinks. Note: Not for food packaging. Use: The heat resistance is not strong. Generally, qualified PE cling film will melt when the temperature exceeds 110 ℃, leaving some plastic preparations that cannot be decomposed by the human body. The fat in food can easily dissolve harmful substances in the plastic wrap. Therefore, when food is placed in the microwave, the wrapped plastic wrap must be removed first. Hazardous substances are produced at high temperature, and toxic substances enter the human body with food, which may cause breast cancer, birth defects of newborns and other diseases. Note: Use a microwave to heat up, do not wrap the food in plastic wrap.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
