Note and description of the upgraded hot plate of Hengaode Instrument
The electric heating plate is a device that uses an electric heating alloy wire as a heating material, a mica flexible plate as an insulating material, and a thin metal plate (aluminum plate, stainless steel plate, etc.) for heating. Typical applications are for example electric kettles. The metal tubular electric heating elements are cast into aluminum pans and aluminum plates or welded or embedded on the aluminum pans and aluminum plates to form various shapes of electric heating pans and electric heating. Typical applications include rice cookers, electric irons, electric coffee makers, etc.

note
1. The contact surface of the position where the electric heating element is installed should be flat and free of unevenness.
2. This electric heating element should be placed dry to avoid water immersion to affect its insulation performance.
3. When installing, you should first check whether the installation location is consistent with the specifications of the heating element, and whether the operating voltage is consistent.
4. After installation, you should check whether the inner six-pin bolts, terminal block bolts and terminal bolts are locked, so as not to affect the life of the product due to thermal expansion and contraction.
5. Should be used at the specified voltage.
Explanation
1. The use of this type of electric heating device must be noted that its continuous working temperature should be less than 240 ℃, instantaneously not exceeding 300 ℃.
2. The Guowei silicone electric heating device can work and be under pressure, that is, it can be attached to the heated surface with an auxiliary pressing plate. At this time, the heat conduction is good, and the power density can reach 3W / cm2 when the temperature in the working area does not exceed 240 ° C.
3. Under pasting installation conditions, the working temperature is allowed to be less than 150 ℃.
4. In the case of dry air burning, the power density should be less than 1W / cm2 due to the temperature resistance of the material; in non-continuous conditions, the power density can reach 1.4W / cm2.
5. The selection of working voltage is based on the principle of high power-high voltage, low power-low voltage, special needs can be excluded
6. A power supply that conforms to the requirements of the instrument must be used. The power socket should use a three-hole safety socket and a ground wire.
7. Slight smoke will be generated when first used, which is normal.
8. During use, the heating medium should be prevented from overflowing the vessel and flowing into the cabinet to damage the electrical appliance.
9. If there is a fault during use, the power supply should be cut off and then overhauled.
10. Empty burning is prohibited.

Caulking guns, also called caulk or cartridge guns, dispense a controlled flow of products such as caulk, sealants, and adhesives from a tube or cartridge.
A Manual Caulking Gun consists of a frame which holds the tube, a trigger, and a rod which moves forward when the trigger is depressed, dispensing the product.
Manual caulking guns have a thrust ratio; the higher the thrust ratio, the easier it is to dispense the caulk, sealant, or adhesive. Air-powered or pneumatic caulking guns also have a frame and a trigger, but are used with an air pressure regulator that pushes the product from the tube using air pressure instead of a rod.
