Ceramic Evaporation Boat For Anti-Counterfeit Labels
Product Description
Boron Nitride Ceramics are widely applied in automobile, electronic, electrical engineering, aerospace, medical science, scientific research, for extreme difficult environments such as
electrical insulation, thermal insulation, high temperature resistance, chemical resistance, etc.
Evaporator Boat – Characteristics and Applications
3-Compontent
A.Highest purity in all composition
B.Perfect balance point in thermal shock/high temp mechanical,
which could meet special application.
C.Not used for evaporator boat application
D.Use for crucible for OLED/semi-conductor, where purity and high
temperature properties are critical for the application
2-Component
A.2-Component evaporator boat is the most common product for most
evaporation applications
B.Particularly suitable for food package metallization process
C.Good performance in AlOx metallization process
D.High evaporation compared to 3-component family
Optimizing Each Evaporator Boat Application:
A.Resistance-heated boats or crucibles are used in vacuum chambers
at ~1500–1650℃ (2732–3002℉) to evaporate various metals, including
aluminum (Al), copper (Cu), tin* (Sn), and silver* (Ag).
B.Metallized films and papers are used in the food packaging,
capacitor film, decorative, and electronic industries.
Our ceramic evaporation boats using the most advanced production
equipment and technology,the products produced are of world-class quality and performance.
Our evaporation boats can meet the production of metalized film,
paper, textiles, and other materials, widely used in the vacuum
evaporation packaging materials, capacitor metal vacuum coating,
paper, aluminum plating, bronzing coating, anti-counterfeit labels
such as the aluminum plating industry.
In order to yield the greatest performance of evaporation boats,
achieve the longest service life. Please read the following:
A.Align the clamp on both sides and keep the surface bright and
clean.
B.Make sure good electric contact and heat conduction on end face
and side face by graphite paper.
C.At the first time of heating the new boat, please put a length of
aluminium wire in the centre of cavity for easily confirming the
temperature of boats.
D.The contact point of aluminium wire should be in the length of
1/3 boat or 2/5.
E.The first heating of new boat should not be so fast that will
effect deflation .
F.For the first time of new boat, the speed of transmitting
aluminium wire should be gradually increased from normal 75% and
the power should be gradually induced for the greatest area of
spreading molten aluminium.
G.The time for heating new boat should be 15 minutes, and operate
the evaporation. as above method of transmitting aluminium at
beginning.
H.Please stop transmitting aluminium wire and turn off the power
supply after 30-60 seconds at the end of evaporating each rolls.
