Thermal Insulation Cotton for Prefabricated Concrete Houses
In the field of construction engineering, thermal insulation cotton for prefabricated concrete houses is commonly referred to as engineering quilts, cotton felts, curing felts, maintenance thermal insulation cotton, or wool felts. Here is a detailed introduction:
Engineering Quilts
Engineering quilts are high-performance covering materials specifically designed for thermal insulation and moisture retention during the post-construction curing phase of concrete structures. They belong to the category of industrial special textiles and are not ordinary household bedding. The outer layer is often made of high-density chemical fiber fabric, which is wear-resistant, tear-resistant, and has certain waterproof and stain-resistant properties, effectively protecting the inner filling and extending its service life. Common types of inner fillings include recycled fiber cotton, PP cotton, or specially treated plant fibers (such as cotton). Some high-end products also incorporate an aluminum foil reflective layer to enhance thermal insulation by reflecting radiant heat, further improving their thermal performance.
Cotton Felts
Cotton felts are primarily made from recycled fibers and fabric scraps, processed through carding, combing, and needle-punching. This material is cost-effective and enables the reuse of waste materials, aligning with environmental sustainability principles. Its relatively loose structure provides good air permeability, ensuring adequate air circulation during thermal insulation and preventing quality issues caused by excessive heat buildup on the concrete surface.
Application Scenarios and Functions
These materials are widely used in winter construction, temperature control curing after large-scale concrete pouring, and sun protection and moisture retention during high summer temperatures. In winter, they slow down the dissipation of hydration heat within the concrete, preventing the concrete from freezing and affecting its strength development. In summer, they prevent rapid surface moisture evaporation, avoiding plastic cracks caused by drying shrinkage. Additionally, they effectively prevent temperature cracks due to excessive temperature differentials, ensuring the concrete reaches its designed strength, enhancing its durability, and safeguarding the quality and safety of construction projects.
