The seminar organized by the phantom 26th member of the practicum class. It was an introduction to the process and operation of the company he is working on. Mr. CJ Caipang is the sales supervisor of Chemetall Philippines. Chemetall is a company originated or founded in Germany, dating back to the 19th century when it was part of Metallgesellschaft. Its main product is to sell paint products and services to the automobile, airbus, appliances, metal forming and coil industry. He is in charge with transactions to the different customer providing paint quality service in every part of the nation and they're main headquartered is located in Taguig City. Unfortunately, there is no plant located in the Philippines only a sales office, hopefully in the future they will be able to put up and establish a …show more content…
Next step is to remove the degreasing agent through showering it with water. The rinsing has two basins the pre and after. It is cascaded so that water will be saved and reused for future rinsing. Then it proceeds with the pickling or dusting. In this process, the metal is submerged into a basin of acid to remove the rust or unwanted solid particles. The common acids used for the basin are nitric acid, hydrochloric acid, phosphoric acid and alkalis. He also indicated that the pickling should be done properly or else the powder coating finish will not be as smooth and tough as predicted. It will also result to paint failure and cause corrosion. Leaving the pickling section, it then proceeds to the seed seeding or the conditioning, through the conditioning uniform seed will be planted all over the surface creating a uniform distribution of pigments. Also, refining agents are added to produce fine crystal size and improve the properties. The final step is rinsing to improve corrosion resistance and extend the life of uncoated

But in order to completely seal off the RC a restoration is placed onto the treated RC. This will completely off the RC from the outside environment and prevent wear and abrasion of the RC
Attach a buret clamp (located under the hood) to a ring stand. b. Rinse the burets three times with approximately 10 ml of deionized water. Tilt and rotate the buret in an almost horizontal position (don't let the water spillout!) to rinse the entire inside wall. Allow about 5 ml of water to run through the buret tip on the last rinse. c. Pre-rinse one buret with approximately 5 ml of your Unknown acid solution. Again, rotate the buret to rinse the entire inside wall of the buret as above. d. Clamp the buret in one side of the buret clamp. Place a white piece of paper labeled "Unknown acid" under this buret. Drain any remaining pre-rinse acid solution into a beaker labeled "waste solution". e. Fill this buret with your Unknown acid solution to the zero mark or slightly below it (Not above the zero mark). Make sure the tip of the buret is completely filled and contains no air bubbles. f. Pre-rinse the second buret with approximately 5 ml of standard base solution. Clamp the buret in the other side of the buret clamp. Place a white piece of paper labeled "Standard NaOH solution" under the buret. Drain remaining prerinse NaOH solution into the waste solution beaker. Fill this buret with standard
The concentrate is dried and sent into a reverberatory furnace. The minerals are partly oxidized and melted, resulting in isolated layers. The matte layer refers to the iron-copper sulfide mixture which sinks to the bottom. The slag, which refers to the remaining impurities, floats on top of the matte and the discarded. Sulfur dioxide gases are also collected and made into sulfuric acid for use in hydrometallurgical leaching. The matte is recovered and moved to the converter, a cylindrical vessel into which the copper is poured. Air, lime and silica are added to react with the metal oxide. The slag is removed and the Sulfur dioxide and converted into sulfuric acid, this forms blister copper which is 97-99% pure.
The Pacific Oil Company was formed in 1902 and had been the leader in the manufacturing of a petroleum product Vinyl Chloride Monomer (VCM). This product was Pacific Oil's major product line and was the main component to the manufacturing of plastics, used in many products. In 1979, Pacific Oil had landed a major contract with reliant and had over the years establish a great working partnership. The Reliant Corporation was one of Pacific’s largest and most valued customers and Pacific Oil Company wanted to renegotiate their current contract with the Reliant Corporation, with the goal of extending before it expired. Pacific’s negotiation team, Jean Fontaine, Marketing Vice President for Europe with Paul Gaudin, Marketing Manager of VCM along with representatives Frederick Hauptmann, Senior Purchasing Manager and Egon Zinnser, Regional VP for European operation from The Reliant Corporation, where to spend nearly two year working through the extension of the contract. In the end, the contract settlement was down to a final item that Pacific was not happy about, that may my then loose the extension altogether.
The first thing to consider is the process of cleaning and coating of the boards. This particular process involves the set-up of the machines, the loading of the boards, and the actual cleaning and coating of the said boards by the machines.
Every chemical element or compound have specific properties that make them different than the other. However, these properties help us to understand every element or compound in which they can be used and how we can deal with them. These properties can be chemical properties which are defined as "that property must lead to a change in the substances ' chemical structure", such as heat of combustion and flammability ("Physical and Chemical…"). Also, these properties can be physical properties which are defined as the properties "that can be measured or observed without changing the chemical nature of the substance", such as mass, volume, boiling and freezing points ("Physical and Chemical…"). These two properties are related to each other. For
James has been an employee of Controls Inc. for the past 23 years with an experience in managerial positions of about 15 years. He had a keen interest in working in the Pacific Rim for which he was eventually rewarded a position of Chairman on Board (COB) at the Factory in China.
Firstly, a burette was taken and rinsed with distilled water. Then it was rinsed using the provided NaOH solution.
The mixture was then cooled. Vacuum filtration was then performed on the mixture. This was done by carefully rinsing the precipitate mixture over moist, pre-weighed filter paper into a Büchner flask under vacuum. The residue was then moistened with ethanol while the flask was still under vacuum. The residue and filter paper were placed on a pre-weighed watch glass and weighed. They were then placed in a drying oven for about fifteen minutes and then reweighed. They were reweighed after a further five minutes in the oven and then again after another five minutes, so as to ensure the precipitate had been fully dried.
...process adds from 10 to 15 percent to the price of the fabric, industries still save money because more products can be made in less time. Therefore increasing profits, as well as, reflecting the savings onto the consumers. Other advantages of ‘biostoning’ include, enzymes can be recycled, reduced strain on the industrial washing machines, shorter treatment times, and imperfections are significantly reduced, hence increasing productivity and efficiency. Consequently, this saves the environment by reducing water consumption and waste pollution. The elimination of pumice powder and dust creates a less intensive and safer working condition. However, one problem with biostoning was "back staining" this occurs when loosened dye particles redeposit onto the surface of the fabric, causing discoloration. Such setback can be immensely reduced by optimizing running conditions.
... that involves crushed limestone being mixed with water. This forms a slurry. It is then sparayed into the area containing sulfur dioxide. This reacts to form a aqueos slurry of calcium sulphate. Compressed air is then blown into this slurry. This oxididses the calcium sulfite to form calcium sulphate. The product is treated to remove excess waterand is disposed in land fills.
What exactly is a chemical engineer? Many would say that it is simply a "chemist who builds things" or an "engineer who makes chemicals. However, neither of these statements is completely true. The term "chemical engineer" is not meant to actually describe what it is a chemical engineer does, but to describe what sets it apart from the other branches of engineering: civil, mechanical, and electrical. On average, chemical engineers are numerically the smallest but also the highest paid. It is not a profession the must dwell on the past for comfort and support, for its greatest accomplishments are still yet to come.
For centuries, many scientists and researchers have pondered on the idea of combining two or more substances together to create something new. These explorations have led to the idea of what kind of reactions would occur when diverse elements are combined. This is a concept known as chemistry, a part of science that corresponds with how matter is created from different properties and the process it goes through to create a new substance. Chemistry is a scientific concept that is used in everyday life and is a crucial part in the development of new technology and substances that allow today’s quality of life. The use of chemistry branches off into many different routes, including medical related fields, agriculture, and even in weapons of
