Standardized management

1）As a member unit of the "National Standardization Committee for Thermal Insulation Materials", review the compilation and revision of national standards related to thermal insulation materials. Actively participate in the revision of national standards, and now participate in the revision of national standards: GB/T 16400-2015 "Aluminum silicate wool for thermal insulation and its products", GB/T 13350-2017 "Glass wool for thermal insulation and its products", GB/ T 17794-20XX "Flexible foam rubber and plastic thermal insulation products", GB/T 34336-2017 "Nanoporous aerogel composite thermal insulation products", GB/T 17795-2019 "Glass wool products for building thermal insulation", GB/T 37608- 2019 "Vacuum Insulation Panel" etc. 2) Establish product enterprise standards internally, strictly control product indicators higher than the national standard, and ensure product quality up to standard.

Product quality control

1)Raw material inspection: Raw materials are allowed to be used only after they have passed the inspection; 2)Semi-finished product quality inspection: Regular random inspections are performed on the mixture, glass liquid, etc., and the quality of semi-finished products is adjusted in real time. Each batch of rubber compound is inspected, and it is allowed to be used only after it is qualified; 3)Online product quality inspection: First article inspection and process inspection are carried out on online products to ensure that the quality of online products meets the requirements of plans or standards; 4)Products leave the factory Inspection: The product is inspected before leaving the factory, and allowed to leave the factory after being qualified.

Laboratory quality supervision

1)Annually accept random inspections and supervision by national authoritative laboratories such as "National Glass Fiber Product Quality Supervision and Inspection Center", "National Building Material Testing Center", "National Building Material Product Quality Supervision and Inspection Center", "Hebei Provincial Quality Inspection Institute" and other national authoritative laboratories , There has been no failure for many years. 2)he company headquarters establishes a technological innovation center, in which the laboratory capacity covers the inspection items required by the national standard, and the products produced by the factory are sampled monthly to check the product quality in time.
