How to buy fireproof glass

[China Glass Net] Fireproof glass has good light transmission performance and fire resistance, heat insulation and sound insulation performance. Common fireproof glass has three kinds of laminated composite fireproof glass, wired fireproof glass and hollow fireproof glass. Many buyers of single-piece fire-resistant glass only care about the price of fire-resistant glass, but ignore many important purchase considerations. Here are some tips for you to make a savvy purchaser of fireproof glass.

1. Purchase applicable products: single-piece fireproof glass, divided into 6mm, 8mm, 10mm, 12mm according to thickness, divided into I grade (90 minutes), grade II (60 clocks), and grade III (45 minutes) according to fire resistance grade. , Level IV (30 minutes). Which one to choose, not only according to the strength (or thickness), but also carefully look at the fire resistance rating required for fire acceptance. The high-strength single-piece strontium-potassium fire-resistant glass is more refractory, stronger and more stable than ordinary single-piece fire-proof glass due to the combination of chemical and physical technology.

Second, the selection of qualified manufacturers: due to the registration of production-type fire-resistant glass enterprises subject to fire, environmental protection, registered capital and other conditions, many companies selling fire-resistant glass registered as a trade or sales-oriented enterprises, or the license to operate the production of fire-resistant glass Qualifications, some companies simply do not have industrial and commercial registration, such enterprises do not have production conditions, of course, it is impossible to produce qualified fireproof glass products. The purchaser should check the operation status of the manufacturer and ask him to present the original (or copy) of the business license in order to prevent being deceived.

Third, when purchasing products, check whether there is a sampling report and filing: the current fire department's use of fire protection products is more and more strict, requiring production, sales and use units to be responsible for the life of the fire protection products used, if inadvertent use of counterfeit fire products Or the certificate will bear a large risk of fire acceptance and the risk of accident liability in the future. According to the fire regulations, it must pass the sampling inspection by the public security fire department, and hold the National Fire Protection Material Inspection Center or the National Fixed Fire Extinguishing System and the Refractory Component Quality Inspection Center. The company that produces the type inspection report within the validity period can produce fireproof glass. The inspection report is generally for a period of three years. The inspection report is generally filed at the quality inspection center and the provincial fire brigade. The inspection report should show the contact number and address of the quality inspection center to facilitate the verification of the authenticity of the report. The purchaser must ask the manufacturer whether the original inspection report and the telephone number of the filing agency can be presented for verification.

4. At the time of purchase, the manufacturer is required to issue the "Certificate of Fire Products Supply": to implement the spirit of the directives of the Ministry of Public Security Fire Department on strengthening the supervision and management of fire products, and to regulate the market behavior of the production, sale, installation and use of fire products. All provinces have correspondingly implemented the fire product certification system, and established and implemented the fire product credit system, which mainly includes the following points:

1. For fire-fighting products circulating in the provinces, the production unit shall, when supplying fire-fighting products to the purchaser, also fill in the Certificate of Supply of Fire-fighting Products.

2. When each sales and installation enterprise supplies fire-fighting products to the user, the product manufacturer shall be required to fill in the “Certificate of Supply of Fire-fighting Products”.

3. The "Certificate of Supply of Fire-fighting Products" must be in one-to-one correspondence with the specific supply engineering or use unit. When the construction and use units declare the completion of the fire protection project, they shall submit the "Certificate of Fire Products Supply" along with other completion acceptance materials. Send it to the public security fire department for verification.

4. Fire-fighting products that provide “certification of fire-fighting products supply” by non-production enterprises are regarded as counterfeit products. Therefore, according to the above system, when purchasing a single piece of fireproof glass, it is better to require the manufacturer to issue the "Fireproof Product Supply Certificate" with the goods.

Considering the cost performance of the product, the single-piece fireproof glass is a high-tech product, the production process is more complicated, and the production cost is mainly affected by the production scale and equipment conditions of the enterprise. Buying a single piece of fireproof glass is better combined with product quality and price to consider and purchase.
