影响铝型材静电喷涂用粉末涂料流动性因素探讨
Discussing on the Factors Effecting Liquidity Electrostatic Powder Spraying in Aluminium Profile
摘要
Abstract
The detecting liquidity principle of powder coating and estimate index had been introduced. The effecting factors had been discussed too form resinous polymer, powder particle shape and size, fluidization air quality, spraying environment humidity, coating fluidization additive etc. The relevant process control parameters and measures had been provided. Experimental results had been demonstrated the better process parameters for liquidity of powder coating: resin molecular weight 2000 to 5000, Tg 50～65 ℃, spherical particle shape, size distribution 20～80 μm, fluidization air pressure 0.01～0.1 MPa, moisture less than 15 PPM, and the fluidized coefficient of powder coating 140 or so.关键词
