NTC thermistor resistance and temperature

NTC thermistor is a type of sensitive components. The resistance value of NTC thermistor generally changes with temperature, which is different from general fixed resistors. It is a type of variable resistor and is widely used in various electronic components. Unlike resistance thermometers that use pure metals, the materials used in NTC thermistors are usually ceramics or polymers.

Gear shaft coupling surface nitriding reasons

The outer sleeve with internal teeth and the inner sleeve with external teeth form a gear shaft coupling, which uses the meshing of internal and external teeth to transmit torque. This type of connection can transmit a large torque and allow a relatively large axial offset, and the accuracy of the installation is relatively low.

Types and characteristics of high concentration fixing agent

High concentration fixing agent includes acid fixing powder. Generally speaking, this fixing agent is used to improve the wet fastness of nylon and blended fabrics after dyeing and printing. It can improve the color fastness of nylon fabrics during continuous dyeing. Has little effect on colored light. Strong acid resistance, so it will not stain the white background when printing nylon.
