镀铝锌彩钢板的推荐标准厚度、长度、宽度及其允许偏差见相关产品标准。
1表面状态:由于涂装过程中处理方法的不同,镀锌板的表面状态也不同,如普通锌花、细锌花、平锌花、无锌花、磷化表面等。德国标准还规定了表面坡度。
2镀铝锌彩钢板应外观良好,不得有不利于产品使用的缺陷,如无镀层、孔洞、裂纹、浮渣、镀层厚度过大、划痕、铬酸垢、白锈等,外观缺陷国外标准不明确。订货时应在合同中列出一些具体的缺陷。
三。镀铝锌彩钢板量标准值:镀锌量是表示镀锌板镀锌层厚度的有效方法。镀锌量单位为g/m2。日本、美国、德国标准对镀锌钢板数量的要求。尺寸和规格镀锌板的推荐厚度、长度和宽度及其允许偏差见相关产品标准。
4。镀铝锌彩钢板性能指标:一般来说,只有排样、拉深和拉深铝锌板有拉伸性能要求。其中,布置用镀锌板要求有送料点、抗拉强度、伸长率等,拉拔只要求伸长率。7从标称厚度(增加100倍)+代码G:普通材料,P:高取向材料+铁损保证值(频率为50Hz,最大磁通密度为1.7t时增加100倍)
The recommended standard thickness, length and width of aluminum zinc plate and their allowable deviation are listed in relevant product standards. 1. Surface state: due to the different treatment methods in the coating process, the surface state of galvanized sheet is also different, such as ordinary zinc flower, fine zinc flower, flat zinc flower, no zinc flower and phosphating surface. The German standard also specifies a surface grade. 2. The galvanized sheet shall have good appearance and shall not have defects harmful to the use of the product, such as no plating, holes, cracks and scum, over plating thickness, scratches, chromic acid dirt, white rust, etc. Foreign standards are not clear about appearance defects. Some specific defects should be listed in the contract when ordering. 3. Standard value of galvanizing quantity: galvanizing quantity is an effective method to express the thickness of zinc coating on galvanized sheet. The unit of galvanizing quantity is g / m2. The requirements of Japanese, American and German standards on the quantity of galvanized steel sheet; 4. Dimensions and specifications The recommended thickness, length and width of galvanized sheet and their allowable deviation are listed in relevant product standards. 5. Appearance 6. Performance index: Generally speaking, only the layout, drawing and deep drawing Al Zn plates have tensile performance requirements. Among them, galvanized sheet for layout is required to have feeding point, tensile strength and elongation, etc.; only elongation is required for drawing. 7. From the nominal thickness (the value increased by 100 times) + code G: for ordinary material, P: for high orientation material + guaranteed value of iron loss (the value increased by 100 times when the frequency is 50 Hz and the maximum magnetic flux density is 1.7 T)
