Vacuum aluminized graphite crucible

Vacuum electron beam evaporation graphite crucible

Electron beam evaporation graphite crucible is used to improve evaporation performance. It is mainly applicable to the production process of aluminum composite film formed by evaporating metal aluminum on the surface of film substrates such as CPP, pet and BOPP under vacuum. It is a large number of consuming parts to be used in the production process. The performance and quality of graphite crucible determines its service life, which will directly affect the product quality and production cost of aluminum plated film.

The special graphite crucible made of new graphite composite materials can greatly improve its oxidation resistance, bulk density, flexural and compressive strength, enhance abrasion resistance and hardness, reduce porosity and air permeability, greatly weaken the wetting and erosion ability of molten aluminum and gaseous aluminum molecules, and prolong its service life.

The technical indicators are as follows:

Density ≥ 1.95g/cm3,

Resistivity ≤ 8.9 Ω• M

Compressive strength ≥ 90Mpa,
