水性钢结构防腐涂料的类别与应用

Classification and application of water-borne steel structure anticorrosive coatings

水性钢结构防腐涂料的类别从成膜物来看，分为水性醇酸涂料、水性丙烯酸涂料、水性环氧涂料、水性聚氨酯涂料。从用途来讲呢，就是重防腐涂料和轻防腐涂料，但是怎么样来区分它们呢？其实我们是按照环境的因素来区分防腐级别的。

The categories of waterborne steel structure anticorrosive coatings are divided into waterborne alkyd coatings, waterborne acrylic coatings, waterborne epoxy coatings and waterborne polyurethane coatings. In terms of usage, they are heavy-duty coatings and light anti-corrosive coatings, but how do they distinguish them? In fact, we distinguish the level of anticorrosion according to the environmental factors.

【一共分为五个档：C1、C2、C3、C4、C5、C5m】

There are five files: C1, C2, C3, C4, C5, C5m].

【C1】

[C1]

C1、要求比较低,干膜厚度大概在60u，中档的120u，高档的是180u。他最主要的应用环境是加热的内部，建筑内部，空气洁净如办公室商店学校和宾馆等。

C1, requirements are relatively low, dry film thickness is about 60u, medium 120u, high-grade 180u. His main application environment is the interior of heating, the interior of buildings, the air is clean, such as office stores, schools and hotels.

C2、也属于要求铜钟 一次性止血带 标志桩模具 钢丝轮 流水槽模具 防撞墙模具 检查井钢模具 不锈钢铸件 模锻件比较低的：大气污染较低，大部分属于乡村地带，未加热的地方，低频凝结发生的地方，如库房或者体育馆。

C2, also low in demand, is low in air pollution, mostly in rural areas, unheated places, where low-frequency condensation occurs, such as storeroom or gymnasium.
