Is it true that silica gel desiccant is processed externally?

Silica gel desiccant processing outsourcing processing is true. The gas that will be exerted will be absorbed by the silica gel desiccant, which will affect its use quality, and the appearance will also be yellow. The drying temperature is optimally controlled at 120 degrees.

When heating and drying, the packaging should be unpacked. This is because if the wrappers are dried together, the "heat-sealing material" in the wrappers will melt and volatilize due to heat. The gas that will be exerted will be absorbed by the silica gel desiccant, which will affect its use quality, and the appearance will also be yellow.

Is it true that silica gel desiccant processing is outsourced? Many people have nothing to do at home, and often go to the Internet to search for what to do now to make money, or search for how to start a business, etc., and then it will show a lot of released products ** outsourced processing! Such as:

Assembling pens' garment processing, business opportunities, entrepreneurship, joining, brushing, 2

Here we start with the assembly pen: when we consult these online posting outsourced processing, the other party will ask how many of us are going to do it? Then they will introduce us to how much you can earn by organizing a pen with 1 person, and how much can you earn by building it with 10 people?

In this way, many people are slowly falling into the road of being deceived, first, they have to collect a deposit for freight, and second, they have to collect a deposit for equipment, and various reasons are the best reasons. If you think about it, you will know that the real company will not be like this, and the real company is not afraid that we will make the product bad? Therefore, the company will say that their company will send instructors to your processing place for guidance, please note!

Garment outgoing processing: now many garment processing factories have no business to do, so they will search for garment outward processing on the Internet, and then will show a lot of garment processing, and the amount is very large, the workmanship is also very simple, anyway, the requirements are not high, at this time we will think that the opportunity is coming, in fact, it is not as simple as we think, these are **, 1 also to collect the deposit first, 2 when we pay the deposit, they will also find excuses to say other costs and so on, anyway, it is**, please note!

Garment outsourced processing: Now many garment processing factories have no business to do, so they will search for garment outgoing processing on the Internet, and then a lot of garment processing will be displayed, and the amount is very large, and the workmanship is also very simple, anyway, the requirements are not high, at this time we will think of the opportunity to come, 5

In fact, it's not as simple as we think, these are **, 1 also have to collect a deposit first, 2 When we pay the deposit, they will also make excuses to say other expenses and so on, anyway, it's **, please note!

Speaking of business opportunities, entrepreneurship, joining, swiping orders, these are often seen by many people on the Internet, all of which are fraudulent deposits, fraudulent franchise fees, etc., what I said is true, please pay attention! When you see me posting these experiences, you may give me a comment on which one he joins is true and so on!!

It depends on the company's business license, Tianyan check. It is best to go to the site for inspection, and those that need to pay a deposit in advance are generally fake. Please do not be deceived.

Silica gel desiccant is a highly active adsorption material, which is usually prepared by reacting sodium silicate and sulfuric acid, and through a series of post-treatment processes such as aging and acid foaming. Silica gel is an amorphous substance with the chemical formula MSI2 NH2O. Insoluble in water and any solvent, non-toxic and tasteless, chemically stable, does not react with any substance except strong alkali and hydrofluoric acid.

The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace with other similar materials. Silica gel desiccant has high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc.

Silica gel desiccant is a different variety of silica gel packaged in moisture permeable sachets, the main raw material silica gel is a high microporous structure of aqueous silica, non-toxic, tasteless, odorless, chemically stable, with strong moisture absorption, is a highly active adsorption material. It is usually prepared by reacting sodium silicate and sulfuric acid, and through a series of post-treatment processes such as aging and acid foaming. Silica gel is an amorphous substance, its shape is transparent and irregular sphere, and its chemical formula is MSIO2·NH2O.

Therefore, it is widely used in the storage and transportation of instruments, meters, equipment, leather, luggage, footwear, textiles, food, medicines, etc. to control the relative humidity of the environment, reduce and slow down the dampness, mildew and rust of goods.

Silica gel is an amorphous compound with a large surface area, high surface activity, and easy water absorption

msio2 + nh2o =

It can be assumed that H2SiO3 is produced locally, and H2SiO3 is dehydrated only at high temperatures:

H2SIO3 (high temperature) = H2O + SiO2 The reverse process is water absorption, that is, it is easy to absorb water at room temperature, so it is difficult to dehydrate and requires high energy to dehydrate.
