1.将彩钢板剪切成建筑天沟配件。实际上，建筑一般不宜直接选用普通彩钢板。
1. Cut the color steel plate into building gutter accessories. In fact, ordinary color steel plates should not be directly selected for buildings.
2.高温、湿热、酸性区域环境，通常采用涂层热镀锌聚酯彩卷作为屋面彩瓦。
2. In the environment of high temperature, damp heat and acid area, the coated hot-dip galvanized polyester color roll is usually used as the roof color tile.
3.选择将不同厂家、不同涂层厚度、不同生产时间、不同涂层类型的彩卷放在同一工程上，在短时间内造成色差。
3. Choose to put the color rolls of different manufacturers, different coating thickness, different production time and different coating types on the same project to cause color difference in a short time.
4.室内腐蚀氛围重，材料选择不对背面涂层类型、涂层结构、涂层膜厚度没有要求，导致背面涂层剥落。例如：硅酸盐水泥厂。耐火材料厂。
4. The indoor corrosive atmosphere is heavy, the material selection is wrong, and there are no requirements for the back coating type, coating structure and coating film thickness, resulting in the peeling of the back coating. For example: Portland cement plant. Refractory factory.
5.PUR.PIR、粘接耐火材料等用途，未明确彩钢板的用途，误选聚酯背漆彩钢板，造成粘接不良。
5.PUR. PIR, bonding refractory and other purposes, the purpose of color steel plate is not clearly determined, and polyester back painted color steel plate is wrongly selected, resulting in poor bonding.
6.在工业介质环境(如SO2.H2S.NH3.煤灰.冶炼气等。).严重暴露在潮热环境、海洋盐雾环境和强酸碱环境中，彩卷的使用寿命会受到很大影响，建筑设计的选择也没有得到识别。普通彩色涂层卷被错误地选择。
6. In industrial medium environment (such as SO2, H2S, NH3, coal ash, smelting gas, etc.) Seriously exposed to hot and humid environment, marine salt fog environment and strong acid-base environment, the service life of the color paper will be greatly affected, and the choice of architectural design has not been identified. The ordinary color coating roll was incorrectly selected.
7.腐蚀性环境:指含有一定浓度的二氧化硫、氯化物、硫化氢、氟化物、氮氧化物等一种或多种腐蚀性介质、酸雨或酸性空气的环境；
7. Corrosive environment: refers to the environment containing a certain concentration of sulfur dioxide, chloride, hydrogen sulfide, fluoride, nitrogen oxide and other corrosive media, acid rain or acid air;
特定环境:化工厂、冶炼厂、陶瓷厂、煤气发生炉、酸洗车间、电镀车间、造纸车间、染色室、制革车间、火电厂等。含有一定浓度的特定腐蚀介质)、蒸汽环境、工业粉尘环境，距重工业区和海岸线1000米以内。
Specific environment: chemical plant, smelter, ceramic plant, gas generator, pickling workshop, electroplating workshop, papermaking workshop, dyeing room, tanning workshop, thermal power plant, etc. Containing a certain concentration of specific corrosive medium), steam environment and industrial dust environment, within 1000m from the heavy industry zone and coastline.
彩钢夹芯板在上述环境下，普通聚酯彩钢板使用不当，导致漆层脱落、腐蚀、寿命缩短。
In the above environment, the improper use of ordinary polyester color steel plate will lead to the falling off of paint layer, corrosion and shortening of service life.
