Analysis of Breathaboard paper-core bond strength and contributing factors

石膏板占英国所有温室气体排放量的3.5%，低效生产占生命周期排放量的67%。等，2017年\]。在垃圾填埋场内混合石膏板、可生物降解废物和雨水产生有毒硫化氢气体，导致了更严格的废物法规，包括废物隔离和增加的垃圾填埋税（91英镑/吨，在英国不断增加\[HMRC，2018\]），以满足每年处置的1500万吨石膏板废物的需要。目前只有1%的英国石膏板拆除废物得到回收利用[WRAP，2019]。Adaptavate Limited是一家总部位于英国的获奖中小企业，专注于开发和商业化破坏基础行业和建筑市场的材料。该项目加速了世界上第一个石膏替代低碳石膏板的开发，该石膏板由农业作物废料制成，Breathaboard。利用下一代生物基可再生材料和生产方法，Breathaboard响应用户对更环保建筑材料日益增长的需求，提供：上级冷凝、空气质量和能效性能？生物基无毒材料，具有良好的闭环性能？降低生命周期碳排放和自然资源影响。该项目专注于增强Breathaboard的制造商设计和技术验证，实现优化，商业上可行的产品，准备在全球范围内采用。通过与NPL合作，Adaptavate希望通过最先进的分析获得制造质量的关键见解。结果是集中在提供一些新的在线非破坏性质量保证技术。

Plasterboard is responsible for 3.5% of all UK greenhouse gas emissions, with inefficient production accounting for 67% of life cycle emissions \[Maskell, D. et al 2017\].Production of toxic Hydrogen Sulphide gas from the mixing of plasterboard, biodegradable waste and rainwater within landfill has resulted in tighter waste regulations including waste segregation and increased landfill taxes (£91/tonne and increasing in the UK \[HMRC, 2018\]) to cater for the 15m tonnes of plasterboard waste that is disposed annually. Only 1% of UK plasterboard demolition waste is currently recycled \[WRAP, 2019\].Adaptavate Limited, a UK-based, award winning SME, is focused on developing and commercialising materials that disrupt foundation industries and the construction market. This project accelerates the development of a world-first gypsum-alternative low-carbon plasterboard created from agricultural crop waste, Breathaboard.Utilising next generation, bio-based, renewable materials and production methods, Breathaboard responds to growing user demand for more environmentally friendly construction materials, offering:?Superior condensation, air quality and energy efficiency performance?Bio-based, non-toxic materials with excellent closed-loop credentials?Lower lifecycle carbon emissions and natural resource impact.This project focuses on enhancing Breathaboard's design for manufacturer and technical validation, enabling an optimised, commercially viable product, poised for worldwide adoption.Through collaboration with NPL, Adaptavate are looking to gain key insight to manufacturing quality using state of the art analysis. The outcome is focused on delivering some novel in line non destructive quality assurance techniques.
