Processing and application conditions:加工和应用条件

 

· Premixing: Mix the components in a Strand mill for 10-20 second.

· Extrude equipment: Twin-screw extruder with multiple heat zones (Zone 1 y 2: 85°C,  Zone 3 y 4: 95°C)

· Extrudates mix: Milled in Strand mill and sieved through a 90um sieve.

· Substrate: The powder obtain were sprayed on untreated cold-rolled steel panels.

· Temperature cured: 200oC

· Time cured: 15 minutes

· Film thickness applied: 2,0 to 2,5 mils.

· 预混:将组分在研磨机中混合10-20秒。

· ·挤出设备:具有多个加热区的双螺杆挤出机(区域1 y 285°C,区域3 y 495°C

· ·挤出物混合物:在研磨机中研磨并通过90um筛子筛分。

· ·基板:将获得的粉末喷涂在未经处理的冷轧钢板上。

· ·固化温度200oC

· ·固化时间:15分钟

· ·应用的薄膜厚度:2,02.5密耳。

 

Guidelines:指南

 

Should be checked that the sum of epoxy equivalents + OH equivalents in Megamid XL must be equal or higher than 95% of acid equivalents in the employed polyester (example 1: acid equiv= 0.315, Epoxy equiv =0.21, OH equiv = 0.096, Example 2 acid equiv = 0.366, Epoxy equiv =0.209, OH equiv = 0.139)

应检查在Megamid XL中环氧当量+ OH当量的总和必须等于或高于所用聚酯中酸当量的95

(例1:酸当量= 0.315,环氧当量= 0.21OH当量= 0.096 

2酸当量= 0.366,环氧当量= 0.209OH当量= 0.139

The application conditions can affect the gloss, adhesion, chemical resistance and impact resistance. Reduced time or temperature in the curing process may result in decreased the properties of final coating. Take pout this phrase

Since powder coatings are many sensitive to the change of variables and in spite that the quality of THYOSIL Q6045 it is very steady, it is highly recommended to test carefully the other components and the kind of composition, equipment, processing and application conditions to make necessary adjustments to assure correct properties batch to batch.

应用条件会影响光泽,附着力,耐化学性和抗冲击性。 固化过程中减少的时间或温度可能导致最终涂层的性能降低。 要剔除这些缺陷, 由于粉末涂料对变量的变化很敏感,尽管THYOSIL Q6045的质量非常稳定,但强烈建议仔细测试其他成分以及必要的成分,设备,加工和应用条件。 调整以确保批次到批次的正确属性。
