1、 Look at the logo and check the certificate

建筑（安全）中空玻璃設備是指構成中空玻璃的單片玻璃均是已通過3C認證的安全玻璃（鋼化玻璃或夾層玻璃）。2006年建筑（安全）中空玻璃被列入安全玻璃類強制性認證產品。自認證實施以來，很多生產企業通過了產品認證獲得3C證書。企業應該在出售的產品本體上絲印或粘貼3C標志，或者在其小外包裝上和隨附文件（如合格證書）中加施3C標志。選購產品時要查看是否有3C標志，并根據企業信息、工廠編號或產品認證證書等通過網絡查看該產品的生產企業是否通過了強制性產品認證（有3C證書并且有效），產品的型號規格是否在該企業已通過強制認證的能力范圍之內，認證證書狀態是否有效。

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、小型中空玻璃生產線看外觀查質量

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

查看產品的外觀質量，中空玻璃設備不應有妨礙透視的污跡、夾雜物及密封膠飛濺現象，中間間隔層不得有任何異物。密封膠或膠條涂布要均勻連續，與玻璃表面粘接牢固，不得出現氣道、氣泡。密封膠的寬度和深度不得小于GB/T11944-2002標準要求。

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、送樣到有資質的檢測機構進行檢測，確認產品質量

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

中空玻璃產品的關鍵原材料和生產工序較多，原材料質量的好壞以及生產工序的控制水平影響了產品的終質量。并且中空玻璃設備的關鍵性能無法從產品的外觀上識別，只有通過試驗測試才能夠進行確認。因此，建議在選購中空玻璃設備時，特別是批量較大時，一定要抽樣送到第三方檢測機構進行檢驗甄別。

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、小型中空玻璃生產線節能性能的確認

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

在幕墻玻璃和建筑門窗設計時，對中空玻璃的可見光透射比、遮陽系數、傳熱系數、露點等性能參數都有一定的要求。人們為了提高中空玻璃的節能效果，選用不同類型的鍍膜玻璃和著色玻璃來合成中空玻璃。中空玻璃的玻璃原片和結構不同，產品的節能性能不同。因此，在選用中空玻璃之前，一定要先將玻璃送至有資質的第三方檢測機構進行檢測確認，以保證選用的產品性能符合節能設計要求或節能型建筑外窗性能要求。在選用高透Low-E[3]  鍍膜中空玻璃時，因為鍍膜面都被放置在間隔腔內側，不易被辨別和檢測。因此，一定要對中空玻璃設備供應商提供的產品進行抽樣送檢，請檢測機構進行甄別，以防以次充好，甚至以假亂真。

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、小型中空玻璃生產線的搬運、儲存和使用

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

中空玻璃設備一般用木箱或集裝架包裝，玻璃之間應用塑料或紙隔開，玻璃與包裝物之間用輕軟材料填實，以防玻璃劃傷。中空玻璃設備應垂直放置儲存在干燥的室內，搬運和使用時應盡量避免外力沖擊。清潔玻璃時注意不要劃傷或擦傷玻璃表面。

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.
