1: Thermal sprayed aluminum (zinc) composite coating (for long-term corrosion protection)
2: Coating method
3: Yin maintenance method
The above three methods can only be processed twice after the roof tile production is completed to prevent corrosion
It is copolymerized by styrene, acrylonitrile and acrylate rubber. Technically, ASA not only maintains the main characteristics of ABS, but also combines the advantages of PMMA weather resistance, so that the application of the product can be extended to outdoor use. ASA is divided into: general grade, extrusion grade and heat-resistant grade.
Mainly used in chemical plants and scenes with high acid-base level.
PET film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties and dimensional stability, transparency, recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, optical grade mirrors surface protection, etc.
The main feature of this product is the closed foam structure, low thermal conductivity; it has excellent thermal insulation effect, which can save energy consumption: the closed cell structure and dense skin make it difficult for water vapor to pass through, and the water absorption rate is low; the product is flexible , construction and installation is very convenient, saving labor and materials; elegant and clean appearance; suitable for a wide temperature range (-40 ℃ to 120 ℃), good fire resistance, durable; special flame retardant formula, so that the material has excellent fire retardant effect
