The sterilization mechanism and advantages of low-temperature plasmaTime of issue : 2021- 05-18
Plasma refers to the state of matter in which energy is continuously applied to matter from the outside to dissociate it into negative and positive charged particles. Since the state of matter is solid, liquid, gas, and plasma according to the order of energy levels, plasma is habitually called the fourth state.
What is plasma etchingTime of issue : 2021- 05-18
Plasma etching (also known as dry etching) is one of the key processes in integrated circuit manufacturing. Its purpose is to completely copy the mask pattern to the surface of the silicon wafer, and its range covers the size of the front-end CMOS gate (Gate) Control, as well as the etching of back-end metal aluminum and the etching of Via and Trench.
Plasma generator and discharge principleTime of issue : 2021- 05-18
Plasma generator (plasma generator) uses artificial methods to obtain plasma device. Plasma produced by nature is called natural plasma (such as northern lights and lightning), and produced artificially is called laboratory plasma.
The relationship between plasma and surface plasmaTime of issue : 2021- 05-18
Generally speaking of plasma or plasma, everyone thinks of ionized air or high-temperature matter on the sun. However, if you carefully consider the free electron model of metals, the "gas" of free electrons moving in the background of positive ions is also a kind of "plasma".
Surface Plasma Technology ApplicationTime of issue : 2021- 05-18
The surface plasmon wave is a wave that exists near the two interfaces. The refractive index distribution on both sides of the interface has a great influence on the field distribution. This can be used for sensing.
What is plasma polymerizationTime of issue : 2021- 05-18
What is plasma polymerization? Plasma is a partially ionized gas composed of ions and electrons. It can be produced by a plasma generator that can generate glow discharge (such as high frequency, microwave, etc.). Its electron energy is 1-10 electron volts, the electron density is 10□-10□/ml, and the power is about 50 watts.
What is plasma melting?Time of issue : 2021- 05-18
What is plasma smelting? Plasma smelting is mainly based on the ultra-high temperature of plasma and can effectively control the atmosphere in the furnace according to different needs to realize the smelting of special metals or alloys.
Principle of Plasma CoatingTime of issue : 2021- 05-18
等离子喷涂原理是什么?等离子喷涂是采用刚性非转移型等离子弧为热源, 将欲喷涂粉末材料加热到熔融或半熔融状态，在经过高速焰流将其雾化加速喷射到经预处理的工件表面，形成喷涂涂层的一种热喷涂表面加工方法。What is the principle of plasma spraying? Plasma spraying uses a rigid non-transferred plasma arc as the heat source to heat the powder material to be sprayed to a molten or semi-molten state, and then spray it on the surface of the pretreated workpiece after being atomized and accelerated by a high-speed flame flow. , A thermal spraying surface processing method to form spray coating.
Plasma solutionTime of issue : 2021- 05-18
The pungent odors of formaldehyde, chemical fumes, toluene, dioxins, hydrogen sulfide, organic pollution sources and other compounds are the most time-consuming. There are frequent complaints about the surrounding environment, which directly affect life and work?
Plasma instabilityTime of issue : 2021- 05-18
We all know that plasma has many advantages in the application of technology. But we cannot ignore its shortcomings. The editor below sorts out some of the instabilities of the plasma.
