With the continuous development of a country's economy, the construction industry continues to rise, but the energy-saving industry has not matched today's fast-growing economic construction. New energy-saving materials require continuous research and development before they can be applied.

The energy-saving and environmental protection industry is deeply integrated with electronic information technology, new material technology, bio-engineering technology, and high-end equipment manufacturing industry. It integrates application services in traditional industries, is rapidly updated and professional, and promotes the continuous improvement of energy-saving and environmental protection standards. Becoming stricter, policy changes have further promoted the emergence of new technologies and solutions. Policies and technology mutually promote each other and are forming a special development model of energy-saving and environmental protection industries.

How to realize the special development mode of energy saving and environmental protection? Our company passed the FSC (Forest Stewardship Council, Forest Stewardship Council) certification on June 24, 2019. Buying wooden products with the FSC certification mark can avoid buying products derived from endangered tree species or illegal logging, assuring consumers that the products come from forests that can meet the social, economic, and ecological needs of contemporary and future generations. Peaceful support. More than 100 million hectares of forest in about 79 countries have been certified by the FSC.


In order to make traditional manufacturing industry deeply integrate new material technology and develop more professional and environmentally-friendly energy-saving fire doors, Sino-Women constantly researches new materials and new technologies, and jointly develops new fire doors with international authority third-party fairer inertek. Research British standard BS60 / 90 minutes, UL15 / 20/60 test. New energy-saving fire doors currently use surrounding high-performance sealing technology to reduce the loss of air penetration heat, improve air tightness, water tightness, sound insulation, thermal insulation, and other main physical properties. In order to determine whether the energy-saving fire door is qualified, the following standard tests are required.

Tested according to GB / T 8484-2008

Judging based on GB / T 8484-2008

Heat transfer coefficient: K = 1.7W / (m² · K)

Thermal insulation performance: Class 7 of GB / T8484-2008

Test conditions:

Cold box air temperature: 20.0 ℃

Cold box air temperature: -20.0 ℃

Relative humidity of hot box air: 30%

Airflow velocity near the surface of the cold box specimen: 3.0m / s

Hot box airflow: natural convection

In addition to improving the new energy-saving fire doors, the most important thing is to improve the installation technology between the door and the wall, improve the level of integrated energy-saving technology of the door and wall structure and the envelope structure to improve the overall energy-saving effect of the wall. In the design of the new fire door, the heat insulation profile is the core part of the design. The material and structure of the section design of the profile determine the energy-saving effect and quality of the energy-saving fire door.

In addition to structural improvements, hardware accessories occupy a very important position in energy-saving fire doors. Equipped with full fire-resistant hardware accessories, choosing superior hardware materials, hardware accessories can directly affect whether the door is energy-saving and fire-resistant. The new energy-saving fire door uses stainless steel hardware accessories. Stainless steel hardware has higher stability than ordinary hardware and is less prone to deformation. Door gap control is more stable. Not easy to exchange heat. Has better insulation effect.
