BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an angle heating unit and a method of manufacturing the same, and more particularly, to an angle heating unit having a small-diameter pipe having an angular shape which is difficult to manufacture due to the flexibility of heat- The present invention relates to a material-use angle heating unit and a manufacturing method thereof.

Description

TECHNICAL FIELD [0001] The present invention relates to an angled heating unit for small-diameter piping, and an angled heating unit for manufacturing small-

In the case of manufacturing a heating element closely adhered to a pipe when heating a small diameter (1/2 "or less) pipe in a conventional semiconductor process, it is difficult to select a proper heating line because the heating surface is small. Even if the heating line , And the temperature of the heating cable varies depending on the location of the heating cable. This is a problem with the yield and quality of the product. The heating cover for the piping is mainly made of glass fiber or silica fiber. , The fine needle-shaped powder produced by the decomposition of glass fiber or silica fiber has a very harmful effect on the work environment and the health of workers.

In order to solve this problem, the space between the piping and the hot line is widened so that the hot line is evenly arranged. The hot line is heated by heating the space to indirectly heat the pipe to reduce the temperature deviation of the pipe surface, A square angle heating element for producing a quadrangular heating element and closely contacting the valve and piping connection part, minimizing the gap between the heating element and the object surface, and improving heat homogeneity and heat efficiency by smoothly heating the elbow part, And a method for producing the same.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an angle heating unit and a method of manufacturing the same, and more particularly, to an angle heating unit having a small-diameter pipe having an angular shape which is difficult to manufacture due to the flexibility of heat- And more particularly, to an angled heating element for a material and a method of manufacturing the same.

Conventionally used heating covers (heating jackets) for piping are liquids that flow in fluid storage containers, gas pipes, hot water pipes, high temperature steam pipes, filters and fittings, valves, regulators, mass flow controllers And is a product installed so as to directly envelope the external shape of the piping material in order to raise the temperature of the gas to the target temperature or to keep it constant.

Heat-insulating materials such as glass fiber and silica fiber are mainly used for the heating cover for the piping, and the heat-generating part is placed on the inner side of the heat-insulating material and the heat-insulating material is enclosed by the inner skin and the outer skin.

However, when the heating cover is manufactured using the glass fiber or silica fiber as a heat insulating material, when the heating cover is completed in the form of wrapping the outside of the round tube in the form of a tape, It has a disadvantage that the durability is very poor due to the hardening of the rubber material due to high temperature, and it is very difficult to manufacture in the shape of a block in the form of a square tube instead of a circular shape, Even when the glass fiber or the silica fiber is used as an insulating material, even if it is manufactured in an angular shape, if a minute gap or an outer skin of the surrounding envelope is stuck or sewn to perform sewing, Fine particles such as glass fragments or silica fragments come out through fine holes between the needle holes and the yarn formed by . In general, the glass fiber or silica fiber insulation has a needle-like structure, and is easily broken down into very fine particles having a size of several micrometers or less even under ordinary circumstances, In a place where it is necessary to maintain a clean state, such as a semiconductor production line, the above-mentioned minute fine powder is very likely to occur in the process. Which may act as a fatal impurity.

Therefore, in the present invention, when the aramid nonwoven fabric is processed into a heat insulating material, the aramid nonwoven fabric can be processed into a certain type of heating block with a very dense structure. In accordance with the method proposed by the present invention, ), And the degree of adhesion to the outer surface of the piping material in the form of an angle is increased, thereby making it possible to produce an excellent heating element having a small temperature deviation. Therefore, the heating element for the piping used in the production line of the semiconductor production line is very sensitive to the temperature deviation, which has a considerable influence on the yield of the semiconductor production. The angle heating element for the piping material is used Thereby reducing the temperature deviation from the piping material and improving the temperature efficiency, thereby contributing to the improvement of the production yield of the semiconductor and the improvement of the quality.

In addition, the aramid fiber insulation has excellent heat resistance, heat insulation, strong tensile strength and long filament structure, which is not broken down into fine particles. Therefore, the number of the aramid fiber insulation which can be generated in conventional glass fiber or silica fiber, It is very effective to maintain the clean environment of the semiconductor manufacturing factory and the health problem of the human body by the fine powder of less than micrometer.
