What Do You Need To Pay Attention To When Using Desiccant?

What do you need to pay attention to when using Desiccant?
Desiccant is a moisture-proof dehumidification products, the ingredients are many, different products using different types of Desiccant, in the use of Desiccant when the need to pay attention to what matters? In fact, many Desiccant species, it is worth noting Only lime Desiccant.
The main component of the lime Desiccant is calcium oxide, and its water absorption capacity is achieved by chemical reaction, so the water absorption is irreversible.Whether the ambient humidity level, it can maintain more than 35% moisture absorption capacity, more suitable for low temperature preservation , With excellent drying and hygroscopic effects, and the price is low. Can be widely used in food, clothing, tea, leather, footwear, electrical and other industries. The most common use of this type of Desiccant in the snow, but lime Desiccant With a strong alkaline corrosive, often hurt children or the eyes of the elderly thing, has been gradually eliminated. Do not know whether to help you! Added:
Note: Generally speaking, acidic Desiccant can not dry alkaline gas, can dry acid and neutral gas; alkaline Desiccant can not dry acid gas, can dry alkaline gas and neutral gas; neutral Desiccant can be dry But this should only take into account some of the specificity of the law, such as gas and Desiccant between the occurrence of redox reaction, or the formation of complexes, Adducts, etc., can not use this Desiccant to dry the gas. For example:
① can not use concentrated sulfuric acid drying H2S, HBr, HI and other reducing gas, because the two will occur redox reaction, such as: H2S + H2SO4 = 2H2O + SO2 + S ↓
② can not use anhydrous copper sulfate to dry H2S gas, the two will react: CuSO4 + H2S = H2SO4 + CuS ↓
③ can not be dried with anhydrous copper sulfate NH3, the two can react to produce complex: CuSO4 + NH3 = [Cu (NH3) 4] SO4
④ can not be dried with anhydrous CaCl2 NH3, the two will occur complexation reaction, resulting in some adduct: CaCl2 +4 NH3 = CaCl2 * 4NH3 CaCl2 +8 NH3 = CaCl2 * 8NH3
First of all to distinguish the type of Desiccant, there are two common types of Desiccant, according to the composition of the form to determine: one is lime Desiccant,
White lumps, damped into powder; the other is silica gel Desiccant, silica gel is colorless and transparent ball, some are colored, looks like a delicious candy.
Condition 1: eating raw lime Desiccant
Mothers do not panic, do not rush to the hospital.
2. Immediately give the baby drink water or milk. There is a simple way to control the amount of drink: 10 milliliters per kilogram of body weight, can not exceed 200 ml, because excessive may cause vomiting.
3. And then into the hospital for treatment.
Condition 2: eating silicone Desiccant
Mothers do not have to worry too much, because it is another commonly used Desiccant, can not be absorbed in the gastrointestinal tract, can be excreted by feces in vitro, the human body is not toxic. Do not need to do special treatment after taking care, unless the baby appeared dizzy , Vomiting and other special reactions, generally without medical treatment.
Condition three: eating does not identify the Desiccant
1. lime is a white lump, after damp into a powder state.
2. Silicone is a colorless and transparent ball (some are colored, because the addition of other chemicals, this Desiccant can cause the baby's curiosity, they are like delicious candy).
