The method of pit excavation is based on the number of rapeseed cakes, and the plastic film or straw mat is placed in the pit. The crushed rapeseed cake is first soaked in water and the ratio of cake to water is about 1:1; after soaking, it is put into a pit and 500-700 kg of rapeseed cake is loaded per cubic meter. After being filled, the top is covered with grass or plastic film, and the pressure is about 20 cm above the ground, which can be fed two months later.

Ammonia treatment adds 7% ammonia 22 parts per 100 rapeseed cakes. Evenly spray on the pancake, then cover for 3 to 5 hours, then steam in the steamer for 40 to 50 minutes, and finally stir-fried (coke-proof) or dried.

The alkali treatment method adds 24% sodium hydroxide solution of 14.5% to 15.5% per 100 rapeseed cakes, and the other treatments are the same as the ammonia treatment method.

The water washing method fills the water in the cylinder and puts the crushed rapeseed cake into the cake. The proportion of cake water is 1:6. After soaking for one day, the water is filtered off, and then the same proportion of water is soaked for one day for three consecutive times. Can be fed. Or use hot water (80°C in winter, 50～60°C in other seasons) and soak in pancake water ratio of 1:4 to keep the water temperature around 40°C. Summer day soaking, winter soaking for two days, remove with water rinse and filter twice before feeding.

Sapphire Rings

Why choose the sapphire?
1-Thinner and Stronger than Standard Glass Windows
2-Transmits Wavelengths Ranging From UV to Mid-Infrared
3-Features Extreme Surface Hardness and Chemical Resistance

Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm.
