dielectric high temperature Alumina Ceramic seal ring gasket
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
(1) Alumina ceramics burning solid matter
(2) Evaporation, concentration or crystallization of the solution (if there is an evaporating dish, the evaporating dish should be selected. Of course, the crucible can also be used for evaporation, concentration or crystallization of the solution)
Precautions for use
(1) It can be directly heated, can not be quenched after heating, and removed with a forceps
Platinum
(2) placed on the mud triangle when heated
(3) Stirring during evaporation; drying with waste heat when steaming
It can be divided into three categories: graphite crucible, clay crucible and metal crucible.
Among the graphite crucibles, there are three types of general graphite crucibles, heterogeneous graphite crucibles, and high-purity graphite crucibles. Various types of graphite crucibles differ in terms of properties, uses, and conditions of use, as well as raw materials, production methods, process technologies, and product model specifications.
The types of cockroaches are roughly divided into three categories: the first type of smelting copper enamel, its specification "number"; the second type is copper smelting alloy enamel, the special round has 100 numbers, the round has 100 numbers, the third type There are 100 numbers for steelmaking.
The size (size) is usually expressed by the size of the serial number. The No. 1 crucible has a volume capable of melting 1000 g of brass and has a weight of 180 g.When melting different metals or alloys, the amount of melting can be calculated by multiplying the corresponding metal and alloy coefficients.
The raw materials for production can be summarized into three major types. One is crystalline natural graphite, and the other is plastic fire resistance.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
