BONDERIZING PROCESS PDF

Bonderizing is a chemical process to help prevent the corrosion of iron, steel, and other metals. You can also add a definition of Bonderizing yourself The process of treating a metal surface with a zinc phosphate coating in preparation for painting or. Bonderizing Process. Lubricating film for cold forging of aluminum-based metal. Our automatic processing line for aluminum-based metal has been in operation.

It also provides a foothold for the paint, which retards flaking and peeling. It was to overcome the first two of these difficulties of finish maintenance that Pdocess was de- veloped. Passivation can be used for protecting other metals. Rinsing is included, after cleaning; also after the processing operation — after cleaning to make sure that no foreign matter is carried into the Bon- derizing section, and, after processing, to remove any traces of processing solution prior to the chromic acid rinse and drying.

Like all metal finishing methods, Bonderizing requires a clean surface and in both types of Bonder izing installations, the proper cleaning and rinsing equipment is usually included in the installation plans. The process involves ;rocess the metal part into a phosphoric prcoess solution whose key ingredient is often zinc or manganesewith varying additional amounts of nitrateschloratesand copper. The differ onl in the type I Qdamentally, and for all tical purposes the chemical reaction, eating produced and rust-proofing results are the same.

Ferrous metal processing time remains the same, according to the type of production being treated, but in the case of zinc surfaces the processing time for all types of installations is from one to five minutes, varying with the bonderizlng of production treated. Views Read Edit View history. The difficulty of maintaining paint finishes is due to three main causes: Any piece of steel will develop electro-positive and electro- One cm never all before testing just where these O-negative and electro-positive areas will occur, but we have never tailed to get a strong test for us bonderizingg at one area and a strong test for hydroxy] ion.

It similarly cannot be applied to steels containing a large amount of nickelor on stainless procses. Welcome to the most trusted and comprehensive Bonderizing directory on the Internet.

The Parkerizing process cannot be used on non-ferrous metals such as aluminiumbrassor copper. With this continuous sales and ad- vertising effort, widespread knowledge of the value of Parker Processes is be- ing indelibly impressed upon the minds of everyone who uses iron or steel and is creating a preference for this bodnerizing of rust-proofing, which be- comes more and more valuable to all manufacturers who are using Bonder- izing in their finishing operations.

To meet this condition, various accelerated labora- tory tests have been devised to create in a matter of days the effects that might require years of weather- ing to produce.

Bonderizing before finishing will stop the spread of rust and alkali underneath the paint film, even w hen the paint film is scratched sufficiently to allow corrosion to take place. Two to five minutes is usual ly sufficient, depending upon the type of metal being treated. There are no variations necessary in technique or formula, except as to pro- cessing time.

Home Supplier Discovery Bonderizing Suppliers. The considerable list of Bonder ite users is being extended rapidly. Both panels were given typical refrigerator finish.

It is the evolution of a process that has been used by American indus- try for nearly a quarter of a century. Bonderized piece was in perfect condi- tion at hours, while non-Bonderized acid-cleaned sample showed almost im- mediate deterioration.

The patent for this zinc phosphating process using strategic compounds that would remain available in America during a war was granted to inventor Romig of the American Chemical Paint Company in as U. The steaming, humid atmosphere of the kitchen or res- taurant is especially corrosive.

Definition & Meaning Bonderizing

There is another Parker Process that is applicable to a wide variety of articles, which still further extends the Parker service. Locations Served California – South.

British Australian Lead Mfg. In addition to this particular processing temperature, there have also been various similar Parkerizing processes developed and patented that permit using either lower temperatures for energy efficiency or higher temperatures for faster processing. With these process improvements, the end result was that a low-temperature energy-efficient zinc phosphating Parkerizing process, using strategic materials to which the United States had ready access, became the most common phosphating process used during World War II to protect American war materials such as firearms and planes from rust and corrosion.

Its pleasing deep black color harmonizes with most mechanical assem- blies, or may be painted when desired. While the complete process is standardized so procese as procedure is concerned, there is no “standard” style, proceess or shape of tank equipment.

It is ever opening market possibilities for some- products, such as in the case of zinc die castings — by permitting highly durable paint-type finish — so that they can now be assembled into a complete product, where such finish of the die cast parts is necessary from an appearance standpoint. Patent 2,that improved upon the zinc phosphatizing Parkerizing process further.

What is Bonderized Steel? Bonderized material should be immediately painted after installation as the exposed phosphate coating is prone to white rust.

Its purpose is to provide a rust inhibiting paint base that can be produced quickly and easily, and at the same time assure more positive adhesion and durability of applied finishes on iron, steel or zinc surfaces. Patent 1,for an improved manganese phosphating Parkerizing technique.

As the Parker Processes are used on scores of differ- ent products in varied equipment from small still tanks to proxess conveyor equipment, an engineering staff ts maintained to help the prospective user install the type that will be best adapted to his production requirements. This page was last edited on 13 Augustat The Stolle Corporation, W. Various if similar recipes for stovetop kitchen Parkerizing circulate in gun publications at times, and Parkerizing kits are sold by major gun-parts distributors such proocess Brownells.

Bonderizing, especially, is an invisi- ble quality that must be exploited to be of greatest sales and advertising value bonderizint the smart salesman can make it a distinct selling aid, if he will take pains to bring it to the prospect’s at- tention.

In addition, there are many accessory manufac- turers who adopt Bonderizing, not to meet manu- facturer’s specifications, but as a sound quality fea- ture of a bonderizimg product.

The result obtained by Bonderizing is a chemical conversion of the metallic surface to a non-metallic Photomicrograph of a piece of plain, polished sheet steel. In addition to this elaborate laboratory equipment Parker has facilities for applying all their processes under actual production conditions, as well as testing devices with which to determine the prodess rust-resistance of the coatings produced.

The processing proocess is prepared prodess mixing the concentrated Bonderite chemicals with water, in which the cleaned production is immersed for a suf- ficient length of time to produce the characteristic phosphate coating. Bonderizing eliminates, so far as possible, the human element in obtaining a satisfactory surface for painting.

Quite frequently installations are of such s.
