文档介绍：AWX施工注意讨论
AWX 色漆是什么样的色漆?
. AWX basecoat utilizes a waterborne
basecoat binder resin system that is
posed of polyurethane
particles and acrylic latex particles
dispersed in water and co-solvents.
AWX色漆系统采用了聚氨酯分散体和聚
丙烯酸分散体(水性乳液)系统而制造出的
水性色漆。
What Happens when AWX
basecoat dries?AWX色漆是怎样干
燥的?
. When AWX dehydrates, particles touch each
干燥时,高分子颗粒互相接触。
. Then particles coalesce, and merge into a continuous film.
高分子颗粒互相熔合成连续的薄膜。
Particles close together Particles deform Continuity Increases
高分子颗粒靠近高分子颗粒变形连续相增加
Curing Mechanism - Solvent borne
溶剂型色漆的固化机理
1. Atomization空气雾化
2. Solvent evaporation溶剂挥发
3. Viscosity increase黏度增加
4. Polymer molecules e entangled and
form film when the remaining solvent
diffuses out of the
漆膜时聚合物分子链互相纠缠,从形成了漆
膜。

Waterborne Curing is Different
水性涂料挥发时不同的
1. Atomization雾化
2. Dehydration脱水
3. Polymer particles touch each 。
4. Spherical particles deform into polyhedral
成多面体单元。
5. With reduced amounts of water, coalescing solvents left
behind start helping the polymer particles to join together. 随
着水分挥发,助溶剂留下来帮助聚合物颗粒融合。
6. Polymer particles are coalesced and fused together into a
continuous film while the coalescing solvents are
助溶剂挥发后聚合物颗粒彻底结合在一起。

Are Waterborne Basecoats
Free of Solvents?水性涂料是否不含
溶剂?
