At first, underfloor heating used polystyrene boards, this is called polystyrene boards. Nowadays, it is mainly extruded panels and white crystal panels for home decoration. However, the production process of extruded boards determines that special shapes cannot be made, so mushroom boards are generally made from benzene boards. —— Floor heating said
Up to 10%.
Extruded panel: Polystyrene foam is divided into two types: expansion EPS and continuous extrusion XPS. Compared with EPS panel, XPS panel is the third generation of rigid foam insulation material, technologically. it overcomes the complicated production process of EPS panels and has superior properties that cannot be replaced by EPS panels.
This is a plate made byshooting polystyrene resin and other additives through an extrusion process with a continuous, uniform surface layer and closed-cell honeycomb structure. These thick plates with a honeycomb structure have no gaps. This closed-cell structure insulating material can have different pressures (150-500Kpa) while having the same low thermal conductivity (only 0.028W/M.K) and excellent long-lasting insulation and compressive strength up to 220-500Kpa.
Scraprate (SR): The probability that an auxiliary part will become a defective product during the manufacturing process of a certain auxiliary part. The same component can have different loss rates when used to produce different parent parts, so it is defined in the table of materials BOM.
It refers to a certain loss ratio determined by the manufacturer after determining the product consumptions unit and total material consumption based on normal defects and losses during product production.
