Slack Wax
Slack Wax is a by-product of the process of converting lube oil into slack wax base oil. This process involves first separating the aromatic compounds from the lube oil using a solvent and the resulting product is called raffinate. Then, in the second stage, the paraffinic compounds are separated from the raffinate to convert it into base oil.
At this stage, a by-product called slack wax is produced, which is the feedstock for paraffin making units. The oil content can be from 5% to 30%. During the production of raw materials, a solvent extraction method is used to remove the aromatics and the final product is the raffinate. The raffinate is then diluted with a solvent such as methyl ethyl ketone (MEK) to reduce its viscosity to reduce its ability to be refined at low temperatures.
The diluted oil is then cooled from -10 to -20 degrees Celsius. Wax crystals are extracted by filtration and the extracted wax is called slack wax, which is a yellow or brown paraffin wax. It is processed by pressing to reduce the oil content and changing the color through bleaching powders to produce paraffin. Heavy slack wax is the raw material of paraffin wax and is darker than light slack wax.
It is mostly obtained from lubricating oil, which has a melting point of up to 68 ° C and also has an oil content of up to 35%. Slack wax is a mixture of oil and wax, a petroleum product and is a refinery product from crude oil. It is a collection of normal, chain and iso paraffin linear hydrocarbons in which the oil content has been reduced to 15% and its color has become very light.
Slack Wax Application
- Textile, insulation and glass wool industries
- Manufacturing of various industrial products such as candles, polishes, matches, inks, carbon paper
- In paraffin wax emulsions as an adhesive and waterproofing agent in artificial forests
- A waterproofing agent for the manufacture of products such as matches and cables, as well as other items such as inks, polishes, etc.
- For the production of various paraffins, insulation, vaseline and tarpaulin Wax emulsions
Slack wax is a substance composed of wax and oil that is a by-product of motor oil refineries and is the raw material for the production of paraffin. This product is obtained in the process of producing motor oils from a substance called lube cut, which is a waste product of oil.
In the paraffin production process, slack wax is fed into the production system and after performing processes such as deoiling and decolorization, it becomes the final product, namely paraffin wax. The oil obtained in this process is also converted into another product called Foots Oil or Residue Wax, which has many industrial uses.
Slack wax is one of the petroleum products that is classified into three grades: light, heavy and extra heavy. This product is used in the production of candles, matches, soil and grass protection materials, moisture insulation, perfumes, cosmetics, grease, adhesives, etc. This product is yellow or brown in color and melts easily.
What is Slack Wax
Slack Wax is a mixture of paraffin wax and oil derived from crude oil. It is graded based on melting point from light to heavy grades. It is a mixture of alkanes in carbon. It is a derivative of paraffin and is obtained in the paraffin production process.
During the production of paraffin wax, slack wax is entered as a raw material and is finally converted into various grades of paraffin wax after refining, bleaching and bleaching processes. The oil extracted during the degreasing process is a by-product called “residual wax”.
Slack wax is usually brown and varies in terms of fat and oiliness from 10% to 35%. It is divided into three states: extra heavy, heavy and light. Heavy slack wax has a melting point of 62-66 degrees Celsius and light slack wax has a melting point of 47-53 degrees Celsius.
Slack Wax industrial uses
Unlike paraffin wax, slack wax is used as a binder or moisture barrier for the production of industrial products. For example, this unique product is used in candles, emulsions, building boards, matches, rust protection products and moisture vapor barriers, polishes, inks, lubricants and greases, adhesives and sealants, waxes, fuels, perfumes and cosmetics and personal care products.
Carbon paper as well as dustproofing materials or controlled-release materials for industries are also obtained from slack. It has a flash point above 200 °C and an initial boiling point above 280 °C. According to UN GHS criteria, the product is not flammable, but because it contains petroleum, it burns like a fuel.
The product is neither self-reactive nor self-heating and does not undergo exothermic decomposition when heated. It is semi-solid at room temperature and is best stored at about 80°C and away from oxidizing agents.
It is slightly toxic when inhaled, swallowed, or in contact with the skin of laboratory animals.
Slack Wax types and packing
It is a petroleum product and is considered a kind of raw material for paraffin wax. Slack Wax is also a mixture of oil and paraffin in yellow or brown color. Companies usually package Slack in large sizes, IBC tanks and new steel drums.
Sometimes to reduce costs, sometimes at the request of the customer, second-hand drums are used for packaging. It is processed to change the color with special powders after heating to produce paraffin. Various types of this product are used as a binder and moisture insulator and to make a variety of industrial products.
Slack Wax, unlike fully refined waxes and depending on the type of product, has an oil content of 5 to 30 percent. It is also considered a by-product for the production of lubricating oils. Slack Wax can be used as a generating force in many industrial processes.
This product can also be mixed, blended or further refined and the petrolatum formed in the dewaxing process contain significant amounts of oil. That is, usually 10 to 30 percent of the weight of this Wax is oil.
“Oil” in this sense is a mixture of components dissolved at the filtration temperature. It also completely destroys some of the important properties of the wax. Slack fractions are pre-crystallized at high temperatures.
