来源:http://www.jnqkgjg.com 日期:2019-02-27 发布人:admin

彩钢板的基板为冷轧基板,热镀锌基板和电镀锌基板。涂层种类可分为聚酯、硅改性聚酯、偏聚二氟乙烯和塑料溶胶。彩钢板的外表状况可分为涂层板、压花板和印花板,彩钢板广泛用于修建家电和交通运输等行业,关于修建业首要用于钢结构厂房、机场、库房和冷冻等工业及商业修建的屋顶墙面和门等,民用修建选用彩钢板的较少。

The base plate of color steel plate is cold rolled, hot galvanized and electrogalvanized. The types of coatings can be divided into polyester, silicon modified polyester, polyvinylidene fluoride and plastic sol. The appearance of color steel sheets can be divided into coated sheets, embossed sheets and printed sheets. Color steel sheets are widely used in the construction of household appliances and transportation industries. About the construction industry, they are mainly used for roof walls and doors of industrial and commercial construction, such as steel structure factory buildings, airports, warehouses and refrigeration, etc., and less colored steel sheets are used in civil construction.
怎么让彩钢板延长寿命?
How to prolong the life of color steel plate?
先要了解彩钢板常用无损探伤办法,保证彩钢板是   的,没有瑕疵的,彩钢板常用无损探伤办法是:
First of all, we need to understand the common non-destructive testing methods of color steel plate, so as to ensure that the color steel plate is correct and flawless. The common non-destructive testing methods of color steel plate are:
1、超声波探伤钢结构使用超声能透入金属材料的深处,并由一截面进入另一截面时,在界面边缘发作反射的特点来查看零件缺点的一种办法,当超声波束自零件外表由探头通至金属内部,遇到缺点与零件底面时就别离发作反射波来,在萤光屏上形成脉冲波形,根据这些脉冲波形来判断缺点方位和巨细。
1. Ultrasound testing steel structure uses ultrasonic energy to penetrate into the depth of metal material, and when one section enters another section, the reflection characteristics at the edge of the interface can be used to check the defect of the part. When the ultrasonic beam passes from the outside of the part to the inside of the metal from the probe, when the defect meets the bottom of the part, it separates from the reflection wave and forms pulse waveform on the fluorescent screen. These pulse waveforms are used to determine the defect orientation and size.
2、射线探伤:彩钢板使用射线穿透物体来发现物体内部缺点的探伤办法
2. Radiation flaw detection: the method of detecting the internal defects of the object by using the ray penetrating the object in the color steel plate
3、磁粉探伤:是用来检测铁磁性材料外表和近外表缺点的一种检测办法。当工件磁化时,若工件外表有缺点存在,因为缺点处的磁阻增大而发生漏磁,形成部分磁场,磁粉便在此处显示缺点的形状和方位,然后判断缺点的存在。
3. Magnetic particle testing: It is a testing method used to detect the appearance and near-surface defects of ferromagnetic materials. When the workpiece is magnetized, if there are defects in the workpiece's appearance, magnetic leakage occurs due to the increase of the magnetic resistance of the defect, forming a part of the magnetic field, the magnetic powder will show the shape and orientation of the defects, and then judge the existence of the defects.
别的,彩钢板相同需详尽除锈、镀锌或刷涂料,以后隔必定的时刻又要重新修理。现行国度尺度划定,钢材表面堕落别离为A、B、C、D四个等第:   :全面地笼罩氧化皮而险些没有蚀锈的钢材表面;B级:已发生堕落,并且部门氧化皮现已脱落的钢材表面;C级:氧化皮已因堕落而脱落,大约能够刮除,并且有少数点蚀的钢材表面;D级:氧化皮已因堕落而全面剥离,并且已广泛发生点蚀的钢材表面。
In addition, the same color steel plate needs detailed rust removal, galvanizing or paint brushing, and will be repaired at certain times in the future. According to the current national scale, the surface degradation of steel is divided into four parts: A, B, C and D, which cover the oxidized skin completely and almost not corrode the surface of steel; B, which has fallen off and the oxidized skin of the Department has now fallen off; C, which has fallen off because of the decay and can be scraped off, and D, which has a few pitting corrosion; Degraded and fully peeled steel surfaces that have been pitted extensively.
当今社会修建钢材原料均匀,是理想的弹塑性材料。彩钢板的实践受力状况和工程力学核算的结果比较符合,因而彩钢板能够进行可靠地优化设计。修建原料强度高,钢结构重量轻。
In today's society, steel materials are uniform and ideal elastic-plastic materials. The practical stress state of the color steel plate is in good agreement with the results of engineering mechanics calculation, so the color steel plate can be reliably optimized. The construction material has high strength and light weight of steel structure.
因而钢结构构件能够在工厂制作,不受现场条件的限制,条件具有时可方便地到现场装置。一起修建钢材强度高,钢结构重量轻,使钢结构的适应性强,能够缔造高层或大跨度等修建。
Therefore, steel structural members can be manufactured in factories without restriction of site conditions, which can be easily accessed to site devices. The steel structure has high strength and light weight, which makes the steel structure more adaptable and can be used to build high-rise or long-span buildings.
