凡用于彩色钢板与彩色钢板、 彩色钢板与其他材料同的密封胶或密封条, 应满是以下要求:
The sealant or sealing strip used for color steel plate and color steel plate, color steel plate and other materials shall meet the following requirements:
1.选的密封材应为中性, 对钢板和彩涂层无腐性作用
1. The selected sealing material shall be neutral and have no corrosive effect on steel plate and color coating
2.在施工前需进行粘结性能测试的实验, 以保证密封材料与彩钢板间的粘结性能。
2. Before construction, it is necessary to carry out the experiment of bonding performance test to ensure the bonding performance between the sealing material and the color steel plate.
3.进行相容性测试, 以免密封材変质失效和丧失粘结性能
3. Carry out compatibility test to prevent sealing material from texture failure and loss of adhesion
4.是施工过程中要有明确的施工操作的温度规定, 一般应在5-40℃温度下有良好的挤出性能和触变性
4. There should be clear temperature regulations for construction operation during the construction process. Generally, it should have good extrusion performance and thixotropy at the temperature of 5-40 ℃
5.所采用的密封材料也要有良好的抗老化性能、耐紫外线、耐臭和耐水性能。
5. The sealing materials used shall also have good anti-aging performance, UV resistance, odor resistance and water resistance.
6.材料固化后要有良好的低温下延展性，高温下不变软和不降解，保持良好的弹性。
6. After curing, the material shall have good ductility at low temperature, remain soft and non-degradable at high temperature, and maintain good elasticity.
7.采购的密封材必须要有出厂合格证书，操作工艺规定和产品的技术性能数据
7. The purchased sealing materials must have factory certificate, operation process regulations and product technical performance data
