1. Physical Methods These methods include adsorption and ion exchange. Activated carbon is commonly used as an adsorbent to capture cyanide ions from wastewater. However, the effectiveness of these methods often relies on the concentration of cyanide in the water, as lower concentrations may not be efficiently treated.

In agriculture, sodium thiocyanate is employed as a herbicide and a pesticide. Its ability to inhibit certain physiological processes in plants makes it an effective tool for controlling unwanted vegetation. It is particularly useful in managing weeds that are resistant to other herbicides. Additionally, sodium thiocyanate's fungicidal properties contribute to crop protection, helping to prevent the spread of fungal diseases in various agricultural settings. The use of this compound can lead to increased yields and healthier crops, benefiting farmers and the agricultural industry as a whole.

Engine oil seals are vital components in the automotive engine system, designed to prevent the leakage of lubricating oil and the ingress of contaminants. These seals play a critical role in maintaining the proper lubrication of the engine components, including the crankshaft, camshaft, and other critical parts. Engine oil seals contribute to the efficiency and longevity of the engine by preventing oil leaks and ensuring optimal performance.

Elring supplies liquid sealants, head gaskets and also oil seals. The extensive range almost always offers a solution for an engine block and quality is can’t be missed in Elring's product range.
OIL SEAL (LIP SEAL) VS. MECHANICAL SEAL: PROS & CONS OF EACH

Figure 4 shows the features of a JTEKT oil seal.
Early engines used O-rings (also called packing rings or toric joints) as seals (first patented in 1896). These are just mechanical gaskets in the shape of a torus (a circular ring--like a lifesaver), seated in a groove and compressed during assembly between two or more parts. It creates a seal at the interface. However, O-rings require a fluid film to lubricate them. They have limited usefulness in vacuum application and at extremes of temperature. The modern oil seal represents a significant improvement over the simple O-ring because it effectively seals in lubrication and prevents contamination from outside under a wide range of pressures and temperatures.


Raise the front of the car on ramps, apply the handbrake and chock the rear wheels. Clean round the sump and the crankcase , clutch and gearbox. Drain the engine oil (See How to drain engine oil and remove filter ). Use an adequate jack to lift the engine.

A more comprehensive study of aeration by Dinzburg8 showed that even a minimal level of aeration of an aggressive European SF oil led to protection of a VDF/HFP/TFE compound, but to severe deterioration of an HNBR compound. He notes that aeration increases the severity of aging in oil for silicone and acrylic elastomers, while decreasing the severity for FKM elastomers.

rubber sheet white gasket. This involves placing the rubber material into a mold and applying heat and pressure to shape it into the desired form. The resulting gasket is then trimmed to the correct dimensions and surface finished to ensure a proper seal.
The metal case is the exterior (or frame) of the oil seal, the principal function of which is to give rigidity and strength to the seal. The material of the case must be selected depending on the environment where the seals are to be used. Often the metal case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the oil seal in the housing bore. Common case material types are:
Full synthetic oil is ideal for vehicles that demand peak level performance and high levels of lubrication. Full synthetic oil provides higher viscosity levels, resistance to oxidation and thermal breakdown, and helps fight against oil sludge. Plus, it helps improve fuel efficiency and can even increase a vehicle’s horsepower by reducing engine drag.
