About The Principle Of Reduced Iron Powder To Warm Baby Fever And Matters Needing Attention
Reduced iron powder is applied in all aspects of life, warm baby is one of the most common applications. Special reduced iron powder used in warm baby, higher heat, lasts long. Warm baby bottom for reducing iron powder specific about the heating principle.
Reduced iron powder from iron oxide under high heat conditions hydrogen gas or reduction in carbon monoxide gas, mainly composed of loose structure of iron. Because of reduced iron powder is a powder for themselves, along with its micro-structure is very loose, so its surface active, often used in chemical production and laboratory work as good reducing agents. Reduction of iron due to oxidation, so crush classification must be carried out under protective gas, usually based on ultra-fine classification is JZDB nitrogen when crushing classifier for Superfine grinding classification, if only the reduced iron powder by high-precision grade JZDF nitrogen grader instead.
Reduced iron powder warm baby fever principle is very simple, warm baby inside was raw materials gelatine layer, non-woven bag is composed of three parts, raw materials placed within the non-woven bag, glue the gelatin layer used to carry warm clothes. Raw material layer is made of iron, stone, synthetic polymers such as activated carbon, inorganic salts, water, and can occur in the presence of oxygen in the air an exothermic reaction.
Warm baby reduced iron powder from iron oxide under high heat conditions hydrogen gas or reduction in carbon monoxide gas, mainly composed of loose structure of iron. Due to warm itself baby iron powder is a powder, along with its micro-structure is very loose, so its surface active, often used in chemical production and laboratory work as good reducing agents. Warm baby powder when you restore, the following considerations:
1. warm baby powdered iron kiln cars before entering the kiln, tank per vehicle should be checked whether the requirement to place stable, ensure that the tank put no super high and wide, avoid have collided with the door, or in the kiln collapsed.
2. loading should wear gloves to prevent throwing hand, unloading shall, after cooling tank and should wear heat-resistant gloves to prevent burns.
3. ignite warm baby powder before the nozzle to the gas Poker, small open gas valves, lighted after the nozzle, then adjust the air valve and full combustion of the gas valve.
4. warm baby powder in the work of restoring always check the rail joint, tractor and pusher mechanism is flexible and reliable, if there is any problem to be repaired in a timely manner.
5. feed tanks, trucks should be placed in order, not block passage.
6. warm baby powder into the kiln maintenance should be carried out at the kiln's temperature down to room temperature, gas furnaces into maintenance, shall be located outside the furnace's guardianship and wearing gas masks.
