The main materials of the two-shank holder include:Stainless steel: It is used to make the clip part of the two-shank holder. Stainless steel has good corrosion resistance, strength and toughness,
which can ensure that the clip is not easy to rust or deform during use, and can firmly hold the molybdenum disilicide heating element.
Ceramics: It is used to make the ceramic blocks in the two-shank holder. Ceramics have the characteristics of high temperature resistance and
good insulation performance, and can maintain stable performance in a high-temperature environment, providing good support and insulation
protection for the heating element.
High-temperature ceramic fiber: It is used to make the insulation board. This material has excellent high-temperature resistance performance,
which can effectively block the heat transfer and reduce the heat loss. At the same time, it also has a certain degree of flexibility and insulation
performance, which helps to improve the overall insulation effect of the two-shank holder and ensure its normal use in a high-temperature
environment.
Precautions for Use
Temperature Limit: Although the materials used in the two-shank holder have high-temperature resistance, there is still a certain temperature limit. During use, it is necessary to ensure that the operating temperature of the molybdenum disilicide heating element is within the range that the two-shank holder can withstand. Generally speaking, the high-temperature ceramic fiber insulation board can withstand a relatively high temperature, but it is also necessary to avoid exceeding its limit temperature to prevent affecting the insulation effect and the service life of the holder.
Avoid Mechanical Impact: During the operation of the equipment, it is necessary to avoid mechanical impacts, such as collisions and vibrations, on the two-shank holder and the heating element to prevent the loosening of the stainless steel clips, the cracking of the ceramic blocks, or the damage to the heating element.
Regular Inspection and Maintenance: Regularly check the condition of the two-shank holder, and check whether the stainless steel clips are loose or rusty, whether the ceramic blocks have cracks or damages, and whether the insulation board is aged or damaged. If there are any problems, the corresponding components should be replaced in a timely manner to ensure the normal operation of the heating element and the safety of use.
Prevent Impurity Contamination: It is necessary to prevent impurities such as dust and metal shavings from entering the contact area between the two-shank holder and the heating element to avoid affecting the fixing effect and the performance of the heating element. When necessary, appropriate protective measures can be taken, such as installing a dust cover.
Electrical Connection Safety: When connecting the electrical circuits of the molybdenum disilicide heating element, it is necessary to ensure that the wiring is firm and correct to avoid electrical safety problems such as short circuits and electric leakage. At the same time, according to the power and operating current of the heating element, select the appropriate wire gauge and electrical protection device.
