一。不同的底漆在附着力、韧性、耐蚀性等方面有一定的差异。环氧树脂对基材的附着力好,耐腐蚀性高,但韧性是另一种底漆。聚酯与基体结合强度好,韧性好,但耐腐蚀环境不如环氧树脂。聚氨酯是一种综合性能优良的底漆。底漆通常由供应商根据生产方法、用途、腐蚀环境、配套和涂装关系来选择。
2。一般情况下,耐蚀性随涂层材料厚度的增加而增加。订货时,应根据网络环境腐蚀、系统使用寿命、耐久性等因素确定涂层厚度。
三。不同表面处理的硬度、柔韧性、附着力和耐久性不同。聚酯是我国应用最广泛的涂料,具有一般耐久性设计,硬度和韧性好,价格适中。有机硅改性聚酯的耐久性、光泽和保色性较高,但韧性略有下降。高耐候聚酯具有更高的性能和价格。乙烯基聚偏氟乙烯具有优良的耐久性、韧性,但硬度低、色泽低、价格高。彩涂板面漆可根据不同用途直接影响1536917957775214.jpg的网络环境腐蚀性、使用寿命、耐久性、加工方式和变形程度。

1. Different primers have some differences in adhesion, toughness, corrosion resistance and so on. Epoxy has good adhesion to substrate, high corrosion resistance, but toughness is another primer. The bonding strength between polyester and substrate is good, toughness is excellent, but the corrosion resistance environment is not as good as epoxy. Polyurethane is a kind of primer with good comprehensive properties. Primers are usually selected by the supplier according to the production method, use, corrosive environment, matching and finishing relationship.
2. Generally, the corrosion resistance increases with the thickness of coating materials. When ordering, the coating thickness shall be determined according to the corrosion of the network environment, service life of the system, durability and other factors.
3. The hardness, flexibility, adhesion and durability of different types of finish are different. Polyester is the most widely used coating in China, with general durability design, good hardness and toughness, and moderate price. The durability, luster and color retention of the silicone modified polyester are higher, but the toughness is slightly reduced. The high weather resistant polyester has higher performance and price. Vinyl polyvinylidene fluoride has excellent durability, good toughness, but low hardness, low color and high price. The top coat of color coated plate can make the network environment corrosiveness, service life, durability, processing mode and deformation degree of 1536917957775214.jpg directly affect according to different purposes.
