Description

Anti-rust sponge is produced on the basis of silica for washing and de-rusting

[0001] Chemistry- Detergent / a type of sponge with a different shape and structure for washing and rust removal, whose main base is silica to create roughness.

[0002] Solving the problem without using melamine materials and with the ability to produce a product with several special features of rust removal.

[0003] Anti-rust sponge for washing and de-rusting is based on silica for cover and removal of rust and cleanliness of dishes. Our sponge is produced very cheaply and has a wider scope of application. Our sponge is able to remove any stain, rust and grease from any surface (with any material). It is very difficult to remove rust from metals, so it is necessary to remove this rust to prove the different function of the sponge.

[0004] Washing and observing hygiene is inevitable; Also, de-rusting metals is very difficult. Therefore, the use of sponges and steel wool to cover and remove rust is very common but very difficult. For the above reasons, it is necessary to rub off this rust in order to increase the functionality of the metal parts. This problem is always present in most metals. According to the above description, the claimed invention was designed with the following objectives:

[0005] 1. De-rusting of metal parts, kitchenware and home appliances

[0006] 2. Increasing the efficiency of metals

[0007] 3. Increasing hygiene and creating a multifunctional invention.

[0008] Anti-rust sponge is produced on the basis of silica for washing and de-rusting. Sponge production is not the same as polyurethane foam production; Because the manufacturer must change the density of the sponge according to its industrial application, so he must formulate it himself. The main material used in making this sponge is very innovative and unique. The ingredients and characteristics of each are as follows:

[0009] Polyol resin: They are divided into two groups, petroleum and vegetable, according to their origin. Also, in terms of chemical structure, they are divided into two categories: polyether polyol and polyester polyol. Silicone oil: The main function of silicone oil is as a surfactant. This material keeps the interactions of the created air molecules and the polyol chains next to the air molecules and finally creates a uniform structure.

[0010] Foaming agents: are agents that produce gas and cause the polyol resin to harden and become porous with air. Foaming agents are divided into two categories: chemical and physical. Chemical foaming agent: water Physical foaming agent: methylene chloride gas (it is liquid, but because it evaporates quickly, it is called methylene gas.)

[0011] Catalysts: As their name suggests, the task of these materials is to promote reactions.

[0012] Generally, there are 2 types of catalysts in the production of simple sponges: A. Amine catalyst: Its task is to advance the reaction of TDI and water, which causes the formation of gas and foam structure.B. Metal catalyst or Tin: whose task is to advance the reaction of TDI and polyol.

[0013] Isocyanates: Toluene diisocyanate (TDI) is used to produce sponges. Because TDI has two functional groups and it reacts with water on one end and with polyol on the other end (this property makes the sponge softer) The above items are necessary materials for sponge production. To produce a versatile sponge, new and unique changes must be made in the production process and some innovative materials should be used during production and afterwards. Polyvinyl pyrrolidone: causes adhesion of excess particles and spongy tissues and absorbs surrounding moisture. Despite the increase in temperature during the formation of the sponge, polyvinyl pyrrolidone maintains its properties due to its high thermal stability and increases the density of the sponge tissue.

[0014] Polyvinyl alcohol:

[0015] - elasticity factor multiper

[0016] - Increasing the continuity of sponge tissues and thickening of the tissues

[0017] - Continuity of sponges and additional materials that didn’t include in production reactions, such as fillers

[0018] - Increasing the resistance of the sponge against solvents and oils.

[0019] Fillers: These are materials such as silica powder or barley husk powder, which are used to create some mechanical properties of the sponge and make the cost of the sponge cheaper.

[0020] Texapon: sodium lauryl sulfate or Texapon is a fat dissolving agent, a foaming and puffing agent, and an accelerator of material dissolution.

[0021] Dilute oxalic acid:

[0022] - Increasing the efficiency of the sponge

[0023] - Accelerate rust removal

[0024] - Polishing metal surfaces

[0025] Micronized sugar: It is used to improve the quality of the bonds between the components of the sponge and the ingredients added to the new formula of the sponge. In this formulation, we first prepare a solution of (8%) polyvinyl alcohol and (1.2%) polyvinyl pyrrolidone (step 1). Then we prepare the polyol and bring its temperature to 29 degrees Celsius (of course, not with heat, but we must bring the ambient temperature to 28-29 degrees) (step 2). We put the base on 100 parts or 100 grams of polyol. So, for example, we add 100 grams of polyol to 2.6 grams of 8% polyvinyl alcohol. (To homogenize the combination of 8% polyvinyl alcohol and 2 / 1% polyvinyl pyrrolidone, we use warm water and let 24 hours pass from their production.)We call this solution (polyol + polyvinyl alcohol) as solution number one (step 3).Then we mix 3.8 grams of 1.2% solution of polyvinyl pyrrolidone with 12 grams of micronized silica (The second prepare a solution) (step 4).And then we combine 2.4 grams of water and 1 gram of silicone oil (The Third prepare a solution) (step 5).Now we have to prepare the catalysts; For this, we combine 0.15 grams of amine catalyst (known as Dapco in Iran) and 0.2 grams of metal or tin catalyst, which is methylene gas, and mix well until foam is created (the fourth prepare a solution) (Step 6). Now we mix the composition The second prepare a solution and 3 (step 7), and then we combine the resulting mixture with the fourth prepare a solution (catalysts) (step 8).In the next step, we add the resulting composition to solution number 1 (combination of polyol and polyvinyl alcohol) and mix (step 9).Then add 53 grams of toluene diisocyanate (TDI) and stir the mixture for 6-7 seconds (step 10).And then we transfer it to the mold to form a sponge (step 11).Finally, depending on the needs of homes or industrial consumption, it is cut into different sizes and dimensions. Then, to increase the quality of the sponge, we prepare the following mixture and feed it to the sponge (step 12): At first, we prepare 50 grams of 11% oxalic acid solution and then 50 grams of 14% sucrose solution. And we combine them together and finally add 22 grams of Texapen (2.5% N70) and mix well.

[0026] This sponge has a very high de-rusting power and since, in addition to the new formulation of this sponge, the shape of this sponge is also very unique, therefore de-rusting all points without the need for sanding is possible.

[0027] The material and formulation of my sponge is different from other sponges in the world.

[0028] In the production of common sponges, melamine particles are used, which does not have much cleaning power, and the scope of its applications is limited, and they are mostly used for removing the ordinary lines of the car body and polishing.

[0029] The process of producing other sponges is very expensive, but in the process of producing new sponges, I did not use melamine powders and used other materials in an innovative way, so my sponge is produced much cheaper.

[0030] After all, the application domain of our sponge is much wider and in one sentence it can be said that our sponge is able to remove any stain, rust and grease from any surface (with any material).

[0031] Sonax sponge does not have the ability to remove the soot inside and outside of copper or iron containers. But our sponge cleans every stain and old rust from every surface. Also, simultaneous use for rust removal and cleaning of dishes is one of the advantages of the claimed spongeFig.1

[0047] Then rinse the mentioned objects and surfaces.

[0048] The process of using the alleged sponge is the same as another sponges, with the difference that the desired result can be achieved by using a small piece of this sponge every time.

[0049] The alleged invention is used in all rust removal and degreasing in industrial and non-industrial uses, but because its main base is silica, it is necessary to pay attention to its roughness in some cases.
