DETAILED DESCRIPTION OF THE INVENTION Brief Summary of the Invention From US Pat. No. 2,876,200;
No. 6; No. 2372052; and No. 2975139. US Pat. No. 2,876,200 describes a method for making a non-separating granular cleaning agent with bleaching blades. There is no disclosure that the product produced by the described method has lubricating properties and also provides good corrosion protection for Fi films, which is rarely the case in the existing patent line. I am referring to the fact that it is not.

High titer soaps (generally containing stearates and/or stearates)? (Tetraboric acid sulfur pentahydrate) and then apply the mixture to the metal surface at a dilution of about 12 to 20 oz. It is common practice to produce dry film metal drawing formulations by applying ζO and drying the workpiece to produce the desired thin film coating. Although it is possible to form various metal shapes in a press on workpieces that can be coated with these conventional soap-1 sand compositions, excessive die wear and poor die life may result. It is impossible to create a harsh alternative. In case of such severe deformation, it is not possible to produce an excellent workpiece because the so deformed moldings show the initial welding together with the wrinkled paper or die; such welding Weld and then take the form of galling.Furthermore, these conventional soap and borage compositions make them virtually non-corrosive to the ferrous substrate, i.e., conventional soap applied on carbon steel surfaces. A borax coating is used on standard IJ-brand condensing cabinets, where nine surfaces are coated at 100" F.
(exposed to an atmosphere with uniform condensation of moisture) at 24
Shows uniform and almost complete rust over all steel surfaces in time.

It is necessary to apply a conventional soap-borax dry film-forming solution at elevated temperatures.
'FJ! Solutions at 0 ambient temperature are highly desirable due to the fact that once below +1, they tend to be highly viscous, virtually liquid-like, and sloppy. #1 They have negligible lubricity value and cannot be used as "wet" formulations because of their inability to be applied due to the tendency of their solutions to lubricate at ambient temperatures. Their use as pultrusion compositions is only as dry films.

Not shying away from the limitations associated with conventional soap dry film coatings, the industry is using more expensive compounds such as chlorinated metal oxides and chlorinated molybdenum disulfide, including chlorinated compounds and aggressive pultrusion compounds. A non-aqueous lubricant-type composition was used.

In addition to the added cost of these formulations, they often leave undesirable organic coatings on metal surfaces, presenting cleaning problems.

Now we are surprised to find that some soaps have borax compositions ranging from about -7.6 to less than about FH9 -
It has been discovered that a novel dry film, metal drawing formulation, is formed when fed with an aqueous solution having a .

Typical borax compositions in aqueous solution are at least -9,0
It is. The aqueous compositions of the present invention include dissolving a borate containing a compound that gives a - from about 7.6 to less than about 9.0 in a solution of 0.01M to saturation in neutral water; prepared by mixing with a suitable soap. On the other hand, in the borax solution or solution at least about 9
．． Solutions of other borate-containing compounds giving a − of 0 are approximately 7
．． Due to the unique properties of this compound as a dry film, it may be subject to adjustment with an organic or organic compound to reduce the concentration of the solution within the range of 6 to less than about 9.0. In addition, aqueous solutions in the above-mentioned range can function well as wet films compared to conventional paste-type pultrusion formulations.

DETAILED DESCRIPTION OF THE INVENTION In the following examples for the preparation and use of compositions of the present invention, corrosion tests were carried out using a Q-C-T cyclic environmental tester (C
yali@Env1r*nm*ntal TRI mouth cap)
I did it.

Also, in the following example, the pullability of a coated nine-strip die can be measured by the use of a machine consisting essentially of two components, the first component of which holds the flat die in place and is fixed during the test. On the other hand, keep the die and testus) in the guiboot tank assembly that gives the hydraulic pressure in the IJ.

The second component is a gripper/pulley that holds one end of the test strip and moves the other end of the test strip upwardly through the fixed die.

The force required to move the gripper while the test strip is between the dies provides a measure of the lubrication overcome by the coating on the test strip.

According to the test procedure, the cold pressure of standard QD-412 is
Tasteel's Test Notera Nell (Q--1 Nell Co,
) in the test solution for 2 minutes and soaked for at least 2 hours. No difference was observed when Nine and Esono-Nel were open-dried at 1501 for 10 minutes. Two 7-rat dies were cleaned with isopropyl alcohol to remove any remaining lubricant from the previous test, removed with fine grade emery, and again soaked with alcohol. The coated test strips were then washed with isopropyl alcohol. The other end of the test strip was placed between the dies and a load was applied against the die.The other end of the test strip was grabbed and placed between the jaws of the assembly to start the machine.The grip assembly was moved upwards and the test strip This gives a uniform and consistent strip loading rate. At this point the other end of the 17-piece begins to move between the dies. Move at a constant speed? The pressure required to hold the bite assembly is indicated at the pressure needle and automatically recorded by the pressure transducer. After drawing, the die and test strip were inspected for lubricant migration from the test strip in the gouge groove, with no (5), slight (4), moderate (
Rating as 3), intense (2), or overall (1).

Excess migration of the lubricating drawing composition precludes the use of the material in normal production where the material builds up on the die and affects tolerances. The pull-out force was recorded and tested to give an extremely low force.1. In other words, it is 5 for excellent nine-pull ability.
A rating of 1 was given for very high forces, ie very poor pullability. The final pullability rating is 60 for the mass transfer index and 40 for the pull force index.
This is accomplished by rolling tatami mats. These two numbers are then added and rounded to the nearest integer value to obtain the overall pullability rating. If gross transfer of material occurred or the die was marked by the test strip, the pullability index automatically set to 1 (poor) K.

The above apparatus can be used to evaluate aqueous solutions of our compounds as wet films; however, the method used for wet films is different. Conventional water-paced paste formulations are evaluated by determining the force required to pull a coated strip through a die.

The evaluation range for most wet film water-based paste pultrusion compositions is 20% as seen in dry films.

Dip coating of this solution, applied at 60°C and dried for 2 hours at 27°C, gave a pullability rating of 4.

This solution cannot be applied at 30°C because it forms a hard rkt, then the solution is mixed with 1. When treated with hydrochloric acid at pH 1 of 8.4, the solution viscosity decreased to 12 seconds at 60°C and reached a pullability grade of 4. It didn't flow. Then - another 7.8 K - glance good, at this point 6
There was a dramatic decrease in viscosity to 6 seconds at 0°C and 7 seconds at 30°C. Both of these were coated in a 9-test test and gave a pullability rating of 5.

A solution was prepared using the soap At- as described in Example 1. The - of this solution was 8.4. Its viscosity was 6 seconds at 60°C and 7 seconds at 30°C. The pullability rating of Cochindar applied at both temperatures was 5. Then add solution 0- to 1. without changing either viscosity or pullability rating.
The temperature was adjusted to 8.7 at 60°C with ON sodium hydroxide. It was adjusted to 9.3 at 60℃ and 12 at 30℃.
When applied at both temperatures, the viscosity of 1.2 seconds was obtained, and the pullout property of Cocottinda was 4 at a slightly lower temperature, and the pH was 1. ON sodium hydroxide dramatically increases the K11L fluid viscosity to 9.7 over 20 seconds at 60°C. At this viscosity, it becomes extremely difficult to obtain a uniform coating in the test sample;

The line of the solution at 60°C was 9.0. Two sheets of cold rolled mild steel/medium flannel were soaked in this solution for 12 minutes at 27°C.
Air dry for an hour. Then, these medium flannel were tested for corrosion evaluation (Mu87M D-2247-88).
