彩钢卷是一种颜色时应注意什么?河北彩钢卷批发厂家电话_天物彩板
彩色线圈涂料分为树脂涂料、颜料涂料、溶剂涂料和添加剂涂料四部分。溶剂是挥发性成分,其他基本上是不挥发性的。
成膜材料所需的树脂在贮存过程中相当稳定,没有明显的物理或化学变化;成膜过程中,在规定的条件下,可以快速固化成膜。
树脂涂料有很多种。彩色钢卷涂料常用丙烯酸树脂、环氧树脂、聚酯树脂和聚氨酯树脂。不同树脂的物理化学性能不同于耐候性和耐腐蚀性。
颜料必须与树脂结合使用。涂料中颜料的主要作用是使涂膜着色。颜料配比的不同影响涂层的硬度和耐蚀性。
溶剂是液体涂料的重要组成部分,是干燥过程中的挥发性成分。涂料的粘度通常由溶剂调节。用于调节涂料粘度的溶剂称为稀释剂。溶剂型涂料的生产、贮存、涂装、成膜和成膜质量都有很大的影响。
彩钢线圈涂料按用途一般分为建筑和家用电器两大类。根据使用环境选择环氧树脂、聚酯树脂、PVC塑性溶胶、硅改性聚酯、聚偏氟乙烯等建筑涂料。家用电器的油漆通常是彩色聚酯树脂。

What should be paid attention to when color steel coil is a color?

There are four parts of different color coil coatings: resin, pigment, solvent and additive. Solvents are volatile components, others are basically non-volatile.
The resin needed as film-forming material is quite stable during the storage of the coating, and there is no obvious physical or chemical change; in film-forming, under the specified conditions, the film can be cured rapidly.
There are many kinds of resin coatings. Acrylic resin, epoxy resin, polyester resin and polyurethane resin are commonly used in color steel coil coatings. The physical and chemical properties of different resins are different from the weather resistance and corrosion resistance.
Pigments must be used in combination with resins. The main function of pigment in coating is to make the film colored. The difference of pigment ratio affects the hardness and corrosion resistance of the coating.
Solvent is an important part of liquid coating, and it is a volatile component in the drying process. The viscosity of the coating is usually adjusted by solvent. The solvent used to adjust the viscosity of the coating is called diluent. Solvent coating production, storage, coating, film formation and film quality have a great impact.
Color steel coil coating is generally divided into two categories according to its use: Construction and household appliances. According to the use environment, architectural coatings are selected in epoxy resin, polyester resin, PVC plastisol, silicon modified polyester and polyvinylidene fluoride. The paint for household appliances is usually colored polyester resin.
