1.將彩鋼板剪切成建筑天溝配件。實際上，建筑一般不宜直接選用普通彩鋼板。
1. Cut the color steel plate into building gutter accessories. In fact, ordinary color steel plates should not be directly selected for buildings.
2.高溫、濕熱、酸性區域環境，通常采用涂層熱鍍鋅聚酯彩卷作為屋面彩瓦。
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.選擇將不同廠家、不同涂層厚度、不同生產時間、不同涂層類型的彩卷放在同一工程上，在短時間內造成色差。
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.室內腐蝕氛圍重，材料選擇不對背面涂層類型、涂層結構、涂層膜厚度沒有要求，導致背面涂層剝落。例如：硅酸鹽水泥廠。耐火材料廠。
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，未明確彩鋼板的用途，誤選聚酯背漆彩鋼板，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.在工業介質環境(如SO2.H2S.NH3.煤灰.冶煉氣等。).嚴重暴露在潮熱環境、海洋鹽霧環境和強酸堿環境中，彩卷的使用壽命會受到很大影響，建筑設計的選擇也沒有得到識別。普通彩色涂層卷被錯誤地選擇。
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.腐蝕性環境:指含有一定濃度的二氧化硫、氯化物、硫化氫、氟化物、氮氧化物等一種或多種腐蝕性介質、酸雨或酸性空氣的環境；
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;
特定環境:化工廠、冶煉廠、陶瓷廠、煤氣發生爐、酸洗車間、電鍍車間、造紙車間、染色室、制革車間、火電廠等。含有一定濃度的特定腐蝕介質)、蒸汽環境、工業粉塵環境，距重工業區和海岸線1000米以內。
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.
彩鋼夾芯板在上述環境下，普通聚酯彩鋼板使用不當，導致漆層脫落、腐蝕、壽命縮短。
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.
