盈锋经典案例分享|小米SU7汽车工厂

本期分享的是北京小米汽车工厂的建筑案例。该项目使用的产品包括：盈锋镀锌钉、涂层钉、泄爆墙面系统、泄爆屋面系统等，其中，螺钉使用数量超百万套。

As seen above, this issue is sharing the construction case of Beijing Xiaomi Automobile Factory, and the products used in the project include: Infastech galvanized nails, coated nails, explosion-vented wall systems, explosion-vented roofing systems, etc., among which the number of screws used exceeds one million sets.

以上示例产品均为盈锋较常规与畅销的产品，如图，通过观察，我们可以发现这些产品在头型、杆径、长度、外观（如色彩等）上有较明显的区别：

①大型的生产工厂对建筑螺钉的材质、硬度等要求较高，从所列的该项目产品清单也可以看到，我们所提供的产品材质以碳钢为主；

盈锋碳钢螺钉一般采用1022A、10B21高碳钢，且采用进口设备进行渗碳热处理，螺钉表面硬度≥HRC55，HRC40≥芯部硬度≥HRC32，常规12-14TY-B螺钉抗拉力＞11000N，剪切力＞8000N，3mmQ355钢板抗拉拔力≥6000N，较市场一般产品，机械性能更优，也更符合小米汽车工厂项目对建筑螺钉的要求；

②图片所展示的4款产品中，头型、杆长、螺纹、颜色存在明显区别，这些均是根据建筑适用情况与客户具体要求定制的，其中较特殊的就是有色烤漆钉，可根据要求调色；

③当然，重要的是，这些产品会因表面处理方式、盐雾等级的不同被用于不同的建筑区域。

The above example products are all Infastech's more conventional and best-selling products, as shown in the figure, through observation, we can find that these products have obvious differences in head shape, rod diameter, length, appearance (such as color, etc.):

① Large-scale production plants have higher requirements for the material and hardness of construction screws, and it can also be seen from the list of products listed in the project that the product materials we provide are mainly carbon steel;

Infastech carbon steel screws are generally made of 1022A, 10B21 high-carbon steel, and imported equipment is used for carburizing heat treatment, the surface hardness of the screws is higher than HRC55, the core hardness is up to HRC32–40, the tensile strength of conventional 12-14TY-B screws is greater than 11000N, the shear force is greater than 8000N, and the tensile strength of 3mmQ355 steel plate is higher than 6000N, which is quite excellent compared with general products in the market, and is also more in line with the requirements of Xiaomi automobile factory project for construction screws;

② Among the 4 products shown in the picture, there are obvious differences in head type, rod length, thread and color, which are customized according to the specific requirements of the building and the customer.

③ Of course, it is important to note that these products are used in different building areas depending on the surface treatment and salt spray level.

前面我们已了解过，盈锋可提供全套泄压装置（含检测报告、FM认证报告），我们的泄爆产品可与任何带或不带绝缘层的板材、面板、现场组装或车间组装的墙壁一起使用，能有效降低二次伤害的几率，达到保护人员生命及财产安全的目的，更便于爆炸后修复。小米汽车工厂的建设采用盈锋全套泄爆装置，能有效规避生产中可能产生的泄爆问题，也是对盈锋产品的高度认可。

As we have seen before, Infastech can provide a full set of pressure relief devices (including test reports and FM certification reports), and our explosion venting products can be used with any plates, panels, on-site assembly or workshop assembly walls with or without insulation, which can effectively reduce the probability of secondary injury, achieve the purpose of protecting personnel and property safety, and make it easier to repair after explosion.The construction of Xiaomi's automobile factory adopts a full set of explosion venting devices in Infastech, which can effectively avoid the explosion venting problems that may occur in production, and is also a high recognition of Infastech products.

小米汽车工厂建造项目所使用的常规自攻钉中，镀锌钉的数量较多，大家是否还记得盈锋镀锌螺钉有哪些特点呢？盈锋镀锌螺钉采用三价环保锌，膜厚要求≥6um，盐雾要求≥200H无红锈，且要求“零氢脆“、无脆断”现象，可提供材质报告与第三方检测报告。（详细信息可查看“如何快速判定电镀自攻钉的好坏”一篇）

Among the conventional self-tapping nails used in the construction project of Xiaomi automobile factory, the number of galvanized nails is large, do you still remember what are the characteristics of Infastech galvanized screws?Infastech galvanized screws are made of trivalent environmentally friendly zinc, with a minimum film thickness of 6um, a minimum of 200H of salt spray without red rust, and a requirement of "zero hydrogen embrittlement" and no brittleness, and can provide material reports and third-party test reports.(For more information, please refer to the article "How to quickly determine the quality of electroplating self-tapping nails")
