Problems solved by technology

[0003] 1. Catalytic deoxidation of gases: Catalytic deoxidation of gases such as hydrogen or CO has high requirements for equipment, the environment and the quality of employees, is expensive, and is prone to accidents due to improper operation. has greater limitations
[0004] 2. Catalyzed deoxidation with precious metals: This kind of deoxidizer has the advantages of high deoxidation rate and easy operation, and was once popular with users. ) are strict, which also limits its use
Because the effect of this method is worse than that of noble metal catalytic deoxidation, it also has certain application limitations.

specific Embodiment 1

[0049] Below, in conjunction with specific embodiment, the present invention is described further:

[0050] The production method of the low-formaldehyde resin adhesive for the decorative adhesive film paper described in the present embodiment is carried out in the following steps successively:

[0051] 1. Ingredients:

[0052] 1-1. The receiving department cooperates with the warehousing department to check and put the raw materials (activated carbon) into the warehouse; the sorting department screens and classifies the raw materials for storage; the production part performs activated carbon dust removal: use vibrating sieves to remove activated carbon during transportation and storage Dust generated by friction during the process (dust accounts for about 3.5% of the weight of the material, moisture ≤ 2.5%; ash content ≤ 7%, bulk specific gravity: 500g / L;

[0053] 1-2. Weigh 92kg of activated carbon, 10.5kg of KOH and 7.5kg of NaOH respectively; add 10.5kg of KOH and 7.5kg o...

specific Embodiment 2

[0068] The difference between the production method of the low-formaldehyde resin adhesive for decorative adhesive film paper of this implementation and embodiment 1 is:

[0069] Step 1-2 is: Weigh 93kg of activated carbon, 7.5kg of KOH and 10.5kg of NaOH respectively; add 7.5kg of KOH and 10.5kg of NaOH into 282kg of aqueous solution to configure 300kg of working fluid; among them, the active group in the working fluid The weight ratio of the points is respectively: KOH accounts for 2.5%, and NaOH accounts for 3.5%;

[0070] Step 3 Impregnation: Put the activated carbon after the above activation treatment and the working fluid recovered from the reactor into a 500L vat, and impregnate for 1.5H (ensure that the activated carbon can be fully impregnated and the active components can fully enter the activated carbon). After the impregnation is completed, the activated carbon is taken out, and the weight of the remaining working fluid is measured to be 200kg, which means that 10...

specific Embodiment 3

[0075] The difference between the production method of the low-formaldehyde resin adhesive for decorative adhesive film paper of this implementation and embodiment 1 is:

[0076] Step 1-2 is: Weigh 91kg of activated carbon, 13.5kg of KOH and 4.5kg of NaOH respectively; add 13.5kg of KOH and 4.5kg of NaOH into the aqueous solution to prepare 300kg of working fluid; among them, the active components in the working fluid The weight ratios are respectively: KOH accounts for 4.5%, and NaOH accounts for 1.5%;

[0077] Step 3 Impregnation: Put the activated carbon after the above activation treatment and the working fluid recovered from the reactor into a 500L vat, and impregnate for 1.5H (ensure that the activated carbon can be fully impregnated and the active components can fully enter the activated carbon). After the impregnation is completed, the activated carbon is taken out, and the weight of the remaining working fluid is measured to be 200kg, which means that 100 kg of the wo...

Abstract

The invention discloses a carbon deoxidizer and a preparation method thereof. The carbon deoxidizer is prepared from the following raw materials in parts by weight: 91-93 parts of C, 2.5-4.5 parts of KOH, 1.5-3.5 parts of NaOH and 1-3 parts of H2O. The method for preparing the carbon deoxidizer comprises the following steps of: 1) mixing; 2) activation; 3) dipping; 4) dehydration; 5) roasting treatment; and 6) packing after the product sample test is approved, thereby obtaining the carbon deoxidizer. The carbon deoxidizer has superstrong overtemperature resurrection property and is improved in deoxidization capacity; simultaneously, the deoxidizer is low in requirement for the starting point of the reaction temperature, so that the production electricity consumption of an enterprise can be reduced to a large extent and the production cost of the product can be saved; and besides, the carbon deoxidizer further has the characteristics of low cost, stable supply, use safety, simplicity in operation and non-pollution emission.

Description

technical field [0001] The invention relates to a deoxidizer, in particular to a carbon deoxidizer and a preparation method thereof. Background technique [0002] With the development and progress of the industry, the scope of use of deoxidizers is expanding, and the demand is also increasing. Due to the increasing awareness of global environmental protection, how to achieve the unity of high efficiency, energy saving and environmental protection and emission reduction when enterprises use deoxidizers for industrial production is one of the important factors that enterprises should consider when formulating development strategies. Most of the traditional deoxidizers use activated carbon as the main raw material, and they need to be deoxidized with hydrogen when they are used, which will cause potential safety hazards. However, due to the relatively high cost of hydrogen-free deoxygenation, it is easily rejected by investors. At the same time, some methods that use precious...
