Are there any ways to recycle desiccant that has already been used?？ |
 1 |
If the desiccant still available, it can be used in the dryness for saving domestic food and shoes, etc.
Lime desiccant (RAYM) is a particle-like substance before absorbing moisture, while it turns into powder after reacting. If there are still particle-like substances in the bag, the desiccant is still effective.

How to dispose desiccants？ |
| 2 |
It should be abandoned according to the detailed local allowed methods and regulations.
The chemical absorption desiccant （RAYM・DRYMAX）.The raw materials of them would possibly have exothermic reaction instantly when meet water, so it can’t be thrown to washy place. |

If eat the lime desiccant by mistake, how to deal with？ |
| 3 |
When calcium oxide contacts with water, it will react and release heat. If you have any sign of be burned, please turn to the doctor. If the substance you ate is hydrated lime after reaction, don’t worry, rinse your mouth it will be OK.

If you eat silica gel or clay desiccant by mistake, how to deal with？ |
| 4 |
The chemical property of silica gel and clay is steady, so they can’t be assimilated even you eat them by mistake. If you eat it by mistake, please drink a lot of water、milk or tea etc after rinsing your mouth. If enter eyes imprudently, please don't rub and wipe, wash with the running water immediately. |

If you boiled the food together with desiccant and ate it, how to deal with？ |
| 5 |
Desiccants are non-poisonous, so even they oozed out of the pouch and flew into the pan, they have no influence to human body. So don’t need special treatment. If you really very anxious about it, you can consult with the doctor. |

The desiccant expands very big in the food, why？ |
| 6 |
The expanding desiccant is the lime desiccant, whose main element is quicklime (CaO). After it absorbed moisture, it turned into hydrated lime[Ca(OH)2], whose form changed from particles to power and volume increases by 2-2.5 times.
So while designing the desiccant pouch, our company has already considered the problem of its inflation. We strengthen the sack size, which effectively prevent the happening of sack broken.
*Equation : CaO + H2O → Ca（OH）2 |
| 7 |
How to distinguish desiccant from oxygen absorber？ |
| 7 |
The principle of desiccants of keeping food from dampness is by absorbing vapor inside the packing container to a low humidity.
While oxygen absorber is by absorbing oxygen, which effectively prevent food from oxidation, changing color and mildewing.
You can distinguish and use them according to the property and storage purpose of the food.

The category and features of desiccant |
| 8 |
Classified into 2 kinds------- Physical desiccant and chemical desiccant.
The former (RAYM、DRYMAX) absorbing water by chemical reaction with water.
The physical characteristics of the later (Silica gel and clay desiccant [CAREDRY /UNIT PAK] )is steady, it absorbs vapor by pores.

The element of lime desiccant is quicklime, which can release heat sharply when it contacts with water, towards this which countermeasures Nantong OhE has taken？ |

In order to guarantee the security, our company stipulates that the packaging materials must accord with the following standards.
● Intensive standard(refer to the following table): Prevent bag broken caused by external forces(only our company has this technology in China).
● Size standard: Prevent bag broken arising from absorbing moisture and inflating.
● Waterproof standard (use waterproof paper): Prevent raw materials from contacting water
(only our company has this technology in China).
● Weight standard (thickness, weight and material of the packaging material): Prevent bag broken caused by external forces.
● Expressing Benchmark: It is obligated to arise consumer's attention.
● Moisture-penetrating Standard: We do penetrating process for the packaging material inside our company. 80,000 stable vent hole per square meter.
(only our company has this technology in China).

What are the differences between Type A silica gel and Type B？ |
| 10 |
There are two kinds of silica gel who have strong ability of absorbing moisture. One is type A silica gel as long as put it under normal scope of low- humidity circumstance, which mainly apply to keep food and metal dry etc. The other one---- type B, it adsorbs a large amount of moisture in high humidity and discharges gradually in low relative humidity. Type B mainly is used to control the ambient humidity.
Generally speaking, the silica gel desiccant we called is type A silica gel.
The regulation about silica gel capacity refers to JIS (Japanese industrial standard).  |
| 11 |
The silica gel and clay desiccant are both with physical absorption ability, are there any differences between them（CAREDRY/UNITPAK）? |
| 11 |
Because both of them absorb vapor in the air through their pores, we call them physical desiccants. Silica gel is a kind of material with micro-pores, which is made by a chemical process----- from silica sand in the soil to the high purity silicon dioxide.
Clay desiccant is a special substance with micro-pores, whose soil compositions are very active. It is not harmful to the environment if it is separated from the sack and disposed to the natural environment.

After the bundle of desiccants is opened, how to maintain the remnants？ |
| 12 |
If you put the remnants like they are, they will constantly absorbing vapor in the air, which will decline desiccant’s performance. So, you should keep them in the same bag and tie it tight with a elastic band, then put them in a relative shady and cool place. |
| 13 |
Which is better between desiccant and oxygen absorber for preventing metal from getting rusty？ |
| 13 |
The forming reason of the rust (oxide) is mainly the existence of oxygen and water (vapor), so long as remove one of them, it can play a preventing role.
If you choose oxygen absorber, you need packaging materials with high air barrier. If the bag is sealed not very well or exist holes, oxygen absorber will invalid completely. So you must be very careful while using it. In addition, before using it, you must do some actual packing experiments for confirming, because different kinds of metal have different influences affected by oxygen absorber, which may change the color of metal surface. You’d better use well-qualified moisture-proof packaging materials. Comparing with oxygen absorber, desiccant is more economical. It wouldn’t lose the desiccant’s capacity completely because of unqualified heat sealing and small holes. Well, no one is willing to see any problem. If you are still anxious about it, you can add a little amount.

Which type of desiccants is suitable for prevent metal from get rusty？ |
14
|
The raw material of silica gel is acid, even separated by packaging materials; it is not suitable for keeping with metalwork for a long time.
The series of clay desiccant including are belonging to non- deliquescent desiccants, whose PH index presents neutrality. Even they keep in touch with metals, the possibility of getting rusty is very low, so you can use them safely.
DRYMAX can absorb moisture strongly and can keep the bundle in dry condition, so it is with the mildew-proof effect. The main raw material is magnesium chloride. The moisture-penetrating but water-proof packaging material is used. Please note that do not make it contact metal parts directly.
