Tools Gaskets

The gasket is one of many types of seals used on a small slit on the stationary component. Some places use a gasket or cylinder head gasket, for example between and block, between the block and the oil pan. Wearing gasket surface must be flat, clean, dry and no scratches. Firmness fastening two surfaces using the gasket is very important, always based on torque specifications to prevent leakage.

Also known as the gasket gasket is the material used for the sealing room containing a liquid or gas. Perapatannya nature divided into two types, namely;

• Static seals, sealing parts are not moving against one another, such as ga with lid gasket cylinder head, crankcase, and others.
• Dynamic seals, sealing bagianlah is the part that move against each other. This dynamic sealing can be divided into two groups, namely sealing parts that move back and forth against each other and sealing the rotating parts against each other.

Figure 3.23 Various gasket

Divided into groups of gasket material is not metallic, half-metallic and metallic.
a. Not a metallic gasket materials.
1. Apparatus static seal.

• Paper and cardboard, materials made of a mixture of fibers coupled with adhesives and fillers. As the fiber is used as wood fiber, fiber old rags, straw fiber and fiber old paper.
• Fiber, the material consists of layers of paper impregnated (saturated) with artificial resin, fiber is usually used as a gasket plate.
• Cork, this material comes from the bark of the cork tree. This cork tied up in the form of plates and used as a gasket plate.
• Static and dynamic seals Tools
• Leather, leather is tanned animal with chrome acid mineral called chrome skin. Besides leather bracelets are also used in the form of gasket plates, mainly used in the form of cufflinks as a gasket seal for the stem.
• Rubber, this material is made of natural rubber and synthetic rubber types because large kekenyalanya including gasket materials are best. However, this gasket material is only suitable for certain media that is at a temperature, pressure, and speed is not too high. Rubber gasket is used to seal pipapipa water, and others.
• Asbestos, is a magnesium silicate which is found in nature in the form of fibers. In the form of the endurance temperature of approximately 500 0C, however, asbestos is usually given a mixture of rubber and graphite. Be used as a gasket asbestos gasket plate and tube plugs, gasket is made in various forms.
• Politetrafluoreten, thermoplastic plastic is in a state of pure good chemical resistance and durability temperature of approximately 260 0C however, this material is often also added to asbestos as an ingredient impegnasi.
• Politetrafluoereten used as a gasket plate and gasket stopper tube and terseia in various forms.

2. Tool dynamic seals
Cotton and hemp, these materials are derived from plants, such as kenaf yarn, cotton and jute impregnated with lubricants specially selected and woven into a square gasket to be used as a gasket stopper tube.

b. Half-metallic gasket materials.
Static sealing tool

• Rubber with copper gauze, available in the form of pallets.
• Asbestos with copper gauze, Gasket consists of asbestos cloth woven with copper. The whole is impregnated with a heat-resistant mass and then given graphite on one side or both sides
• Asbestos with steel gauze, on both sides of the steel mesh is woven tightly and strong affixed with a thin layer of high pressure.
• Asbestos-coated copper thin, asbestos sati given a thin layer of coated copper and can be obtained as finished goods (bracelets and head gasket).

c. Metallic gasket materials

• Tools static seals, made of steel, copper, baking, lead, aluminum, and nickel. This material is used in the form of bracelets rectangular, round, oval, shape of the lens, or other desired shape.
• Tools dynamic seal made of white metal that is used as a gasket discordant tubes in various forms.
