1、 Look at the logo and check the certificate

建筑（安全）中空玻璃设备是指构成中空玻璃的单片玻璃均是已通过3C认证的安全玻璃（钢化玻璃或夹层玻璃）。2006年建筑（安全）中空玻璃被列入安全玻璃类强制性认证产品。自认证实施以来，很多生产企业通过了产品认证获得3C证书。企业应该在出售的产品本体上丝印或粘贴3C标志，或者在其小外包装上和随附文件（如合格证书）中加施3C标志。选购产品时要查看是否有3C标志，并根据企业信息、工厂编号或产品认证证书等通过网络查看该产品的生产企业是否通过了强制性产品认证（有3C证书并且有效），产品的型号规格是否在该企业已通过强制认证的能力范围之内，认证证书状态是否有效。

Building (safety) insulating glass equipment refers to that the single piece of glass constituting the insulating glass is safety glass (tempered glass or Laminated glass) that has passed 3C certification. In 2006, building (safety) insulated glass was listed as a mandatory certification product for safety glass. Since the implementation of certification, many production enterprises have obtained 3C certificates through product certification. Enterprises should screen print or affix the 3C logo on the products they sell, or apply the 3C logo on their minimum outer packaging and accompanying documents (such as certificates of conformity). When purchasing a product, the first step is to check if it has the 3C mark, and check through the internet whether the production enterprise of the product has passed the mandatory product certification (with a 3C certificate and is valid) based on the enterprise information, factory number, or product certification certificate. The model specifications of the product are within the scope of the enterprise's ability to pass the mandatory certification, and the status of the certification certificate is valid.

二、小型中空玻璃生产线看外观查质量

2、 Check the appearance and quality of small insulating Glass production production line

查看产品的外观质量，中空玻璃设备不应有妨碍透视的污迹、夹杂物及密封胶飞溅现象，中间间隔层不得有任何异物。密封胶或胶条涂布要均匀连续，与玻璃表面粘接牢固，不得出现气道、气泡。密封胶的宽度和深度不得小于GB/T11944-2002标准要求。

Check the appearance quality of the product, and there should be no stains, inclusions, or sealant splashes that hinder the perspective of the hollow glass equipment. There should be no foreign objects in the intermediate interval layer. The application of sealant or adhesive strip should be uniform and continuous, firmly bonded to the glass surface, and there should be no air passages or bubbles. The width and depth of the sealant shall not be less than the requirements of GB/T11944-2002 standard.

三、送样到有资质的检测机构进行检测，确认产品质量

3、 Send samples to qualified testing institutions for testing to confirm product quality

中空玻璃产品的关键原材料和生产工序较多，原材料质量的好坏以及生产工序的控制水平影响了产品的终质量。并且中空玻璃设备的关键性能无法从产品的外观上识别，只有通过试验测试才能够进行确认。因此，建议在选购中空玻璃设备时，特别是批量较大时，一定要抽样送到第三方检测机构进行检验甄别。

There are many key raw materials and production processes for insulating glass products, and the quality of raw materials and the control level of production processes affect the final quality of the product. And the key performance of insulating glass equipment cannot be identified from the appearance of the product, and can only be confirmed through experimental testing. Therefore, it is recommended that when purchasing insulating glass equipment, especially in large batches, samples must be sent to third-party testing institutions for inspection and screening.

四、小型中空玻璃生产线节能性能的确认

4、 Confirmation of energy-saving performance of small insulating Glass production production line

在幕墙玻璃和建筑门窗设计时，对中空玻璃的可见光透射比、遮阳系数、传热系数、露点等性能参数都有一定的要求。人们为了提高中空玻璃的节能效果，选用不同类型的镀膜玻璃和着色玻璃来合成中空玻璃。中空玻璃的玻璃原片和结构不同，产品的节能性能不同。因此，在选用中空玻璃之前，一定要先将玻璃送至有资质的第三方检测机构进行检测确认，以保证选用的产品性能符合节能设计要求或节能型建筑外窗性能要求。在选用高透Low-E[3]  镀膜中空玻璃时，因为镀膜面都被放置在间隔腔内侧，不易被辨别和检测。因此，一定要对中空玻璃设备供应商提供的产品进行抽样送检，请检测机构进行甄别，以防以次充好，甚至以假乱真。

In the design of curtain wall glass and building doors and windows, there are certain requirements for the visible light transmittance, shading coefficient, Heat transfer coefficient, dew point and other performance parameters of insulating glass. In order to improve the energy-saving effect of insulating glass, people choose different types of coated glass and colored glass to synthesize insulating glass. The energy-saving performance of products varies depending on the original glass sheet and structure of insulating glass. Therefore, before selecting insulating glass, it is necessary to send the glass to a qualified third-party testing agency for testing and confirmation to ensure that the performance of the selected product meets the energy-saving design requirements or the performance requirements of energy-saving building exterior windows. When selecting high transmittance Low-E [3] coated insulating glass, it is difficult to distinguish and detect because the coated surfaces are placed inside the spacing cavity. Therefore, it is necessary to sample and inspect the products provided by insulating glass equipment suppliers, and ask professional testing institutions to screen them to prevent them from being replaced by inferior products, or even using fake products as genuine ones.

五、小型中空玻璃生产线的搬运、储存和使用

5、 Handling, storage and use of small insulating Glass production production line

中空玻璃设备一般用木箱或集装架包装，玻璃之间应用塑料或纸隔开，玻璃与包装物之间用轻软材料填实，以防玻璃划伤。中空玻璃设备应垂直放置储存在干燥的室内，搬运和使用时应尽量避免外力冲击。清洁玻璃时注意不要划伤或擦伤玻璃表面。

Hollow glass equipment is generally packaged in wooden boxes or container racks. The glass should be separated by plastic or paper, and soft materials should be used to fill the gap between the glass and the packaging to prevent scratches on the glass. Insulated glass equipment should be stored vertically in a dry room, and external impact should be avoided as much as possible during handling and use. Be careful not to scratch or scratch the glass surface when cleaning the glass.
