Introduction to dishwashers:
A dishwasher is a fast, efficient household appliance used to
automatically clean utensils and cutlery. It usually includes a
dish sink, a nozzle inside the dishwasher, and a dryer that can be
cleaned with water and detergent.
The method of using the dishwasher is usually very simple, the user
only needs to put the utensils in the basket inside the dishwasher,
add the detergent and close the door of the dishwasher. Dishwashers
are programmed to control water temperature and flow, as well as
jet strength, to clean utensils. In general, dishwashers also
provide a drying function, which allows the tableware to dry
quickly after cleaning.
The advantages of dishwashers include saving time and effort, good
dishwashing effect, and a large number of dishes can be cleaned.
The dishwasher is a very practical household appliance for people
who are busy with work, don't have the time or don't like to wash
dishes. At the same time, dishwashers can also save water, because
it usually requires only a small amount of water to wash.
Our company manufactures an-isotropic ceramic strontium ferrite
magnet made by means of wet compression molding.
What is permanent magnet ferrite?
Permanent magnet ferrite is a hexagon structure compound with
uniaxial anisotropy, mainly barium, strontium, lead three kinds of
ferrite and their composite solid solution, there are the same
magnetic and opposite magnetic points, because this kind of ferrite
material in the external magnetization field disappeared, still can
retain a strong constant remanent magnetic property for a long
time, can be used to generate a stable magnetic field on the
external space.
How to determine the performance of the product?
There are four main indicators to measure the performance of
permanent magnet materials: residual magnetism, coercive force,
intrinsic coercive force, and maximum magnetic energy product,The
finished permanent magnet ferrite has a high coercivity and is not
easy to demagnetize after magnetization.
What are the advantages of the permanent magnet ferrite we produce?
1,Stable magnetic properties: permanent magnet ferrite has high
coercivity and remanence, stable magnetic properties, and is not
easily affected by external influences.
2,High temperature resistance: permanent magnet ferrite has good
high temperature resistance and is suitable for use in high
temperature environment.
3,High temperature coefficient of resistance to saturated magnetic
field: The magnetic properties of permanent magnet ferrite decay
slowly at high temperatures, with a high temperature coefficient of
resistance to saturated magnetic field.
4,Low cost: The raw material price of permanent magnet ferrite is
low, the production process is simple, and the cost is relatively
low.
5,Long service life: permanent magnet ferrite has a long service
life, is not easy to demagnetize, low maintenance costs.
6,Good rare earth substitution: permanent magnet ferrite can
replace some rare earth magnets, reduce the dependence on rare
earth and reduce the consumption of rare earth resources.
