彩涂板使用助剂的作用是什么？
用于彩涂板的添加剂是为改善涂层性能而添加的少量添加剂。涂料中添加剂用量少，但效果显著。例如，有些可以提高涂料和薄膜的性能，有些可以缩短干燥时间，有些可以防止薄膜的病理变化。添加剂种类很多，包括干燥剂、固化剂、流平剂、消泡剂、消光剂、稳定剂等。
几乎大多数液体涂料都由一些原材料组成，其中最重要的是树脂，树脂是任何涂料都不可缺少的。可以说，树脂（有时含有溶剂和添加剂）是透明涂料，然后添加颜料形成各种颜色的涂料。
彩涂板的工艺流程如下：彩涂钢板是以冷轧钢板和镀锌钢板为基础，经表面预处理（脱脂、清洗、化学转化）、连续涂布（滚涂法）、烘烤、冷却而成的产品。双涂层双干燥连续彩色涂层机组常用工艺流程为：开卷→ 预处理→ 涂层→ 烘烤→ 后处理→ 卷取。
本发明重量轻、外观美观、防腐性能好，可直接加工。它为建筑业、造船业、汽车制造业、家具业和电气业提供新的原材料。具有以钢代木、高效施工、节能环保的良好效果。
彩涂板制造商生产的彩涂板是以镀锌钢板为基础的彩涂板。除锌保护外，锌层上的有机涂层起到覆盖和隔离作用，可有效防止钢板生锈，使用寿命比镀锌钢板更长。据报道，彩色涂层钢板的使用寿命比镀锌钢板长50%。相同镀锌量、相同镀层和相同镀层厚度的彩涂板在不同区域和零件的使用寿命会有很大差异。
由彩色涂层板制成的建筑物或植物通常在雨水侵蚀下具有较长的使用寿命。否则，它们的使用将受到气体、盐和灰尘作用的影响。因此，在设计中，屋顶倾斜度越大，积聚灰尘和其他污垢的可能性越小，使用寿命越长；不常被雨水冲洗的区域或零件应定期用水冲洗。
The additive used in color coated plate is a small amount of additive added to improve coating performance. The amount of additives in the coating is small, but the effect is remarkable. For example, some can improve the performance of coatings and films,
some can shorten the drying time, and some can prevent pathological changes of films. There are many kinds of additives, including desiccant, curing agent, leveling agent, defoamer, matting agent, stabilizer, etc.
Almost most liquid coatings are composed of some raw materials, the most important of which is resin, which is indispensable for any coating. It can be said that resins (sometimes containing solvents and additives) are transparent coatings, and then pigments
are added to form coatings of various colors.
The process flow of color coated steel plate is as follows: color coated steel plate is a product based on cold-rolled steel plate and galvanized steel plate through surface pretreatment (degreasing,
cleaning and chemical conversion), continuous coating (roll coating method), baking and cooling. The common process flow of double coating double drying continuous color coating unit is as follows: uncoiling → pretreatment → coating → baking → post-treatment
→ coiling.
The color coated plate has the advantages of light weight, beautiful appearance and good anti-corrosion performance, and can be processed directly. It provides new raw materials for construction industry, shipbuilding industry, automobile
manufacturing industry, furniture industry and electrical industry. It has the good effects of replacing wood with steel, efficient construction, energy saving and pollution prevention.
The color coated plate produced by the color coated plate manufacturer
is a color coated plate based on galvanized steel plate. In addition to zinc protection, the organic coating on the zinc layer plays the role of covering and isolation, which can effectively prevent the steel plate from rusting, and the service life is
longer than that of the galvanized steel plate. It is reported that the service life of color coated steel plate is 50% longer than that of galvanized steel plate. The service life of color coated plates with the same amount of zinc plating, the same
coating and the same coating thickness will be very different in different regions and parts.
Buildings or plants made of color coated plates usually have a long service life under rain erosion. Otherwise, their use will be affected by the action
of gas, salt and dust. Therefore, in the design, the greater the inclination of the roof, the less likely it is to accumulate dust and other dirt, and the longer the service life; Areas or parts that are not often washed by rainwater shall be washed with
water regularly.
