Waterproof membrane introduction Waterproof coiled material is mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater leakage. It is a flexible building material product that can be rolled into a roll shape as the engineering foundation There is no leakage connection with the building, which is the first waterproof barrier for the wh
Precautions for first-class polyurethane foam board Thermal insulation materials, as the name suggests, can be used for thermal insulation. Thermal insulation can collect excess heat. In buildings, thermal insulation materials can be used to isolate the outflow of heat in the room, thereby playing the role of thermal insulation. This function of thermal insulation material makes it extremely popu
1. XPS extruded board must ensure that the aging meets the 42-day requirement under natural environmental conditions. If the construction period is tight, backup measures should be taken for 5 days under 60-degree steam curing conditions. In order to avoid the insufficient aging period of the XPS board, it will continue to shrink after being placed on the wall, causing cracking, warping and deform
Brief introduction of XPS extruded board The main raw material of XPS extruded board is polystyrene resin, with an average molecular weight ranging from 170,000 to 500,000, Mw/Mn ≥ 2.6, and auxiliary materials including additives and foaming agents. Most of the blowing agents used by foreign companies do not contain halogenated carbon, but use hydrocarbon blowing agents with a faster replacement
XPS foam insulation board performance and application analysis 1. Overview Extruded polystyrene foam plastic (XPS) is mainly composed of polystyrene du vinyl resin or its copolymer. Adding a small amount of additives, it has a closed-cell structure made by heating and extruding. Rigid foam. It has excellent and long-lasting heat insulation function, unique resistance to steam penetration, extreme
XPS foam insulation board production process 1. Multi-component mixing system The fully automatic computer controls the ratio of various raw materials, adopts the weightless measurement method, and strictly compiles the mixed raw materials according to the settings, laying the foundation for the production of high-end quality products. The feeding system uses vacuum feeding to ensure the sta
Talk about some unknown advantages of XPS extruded board The full name of extruded board is called extruded polystyrene foam board, also known as XPS board. Polystyrene foam is divided into two types: intumescent EPS and continuous extrusion XPS. Compared with EPS sheet, XPS sheet is the third generation of rigid foam insulation material. It overcomes the complicated production process of E
10 advantages of XPS insulation board 1. Why does XPS extruded board not absorb water, has low thermal conductivity, and good thermal insulation effect? XPS extruded board is made of polystyrene, various additives and foaming agent, mixed, melted, pressurized and kneaded in the extruder, extruded through the die, the pressure is released, the foaming agent is vaporized to form tiny bubbles , Enca
