A cloud-based system for verifying and documenting Class-A fire-protection treatment of a wood-framed building using on-site spraying of a clean fire inhibiting chemical (CFIC) liquid. The system includes (i) a data center with web, application and database servers for supporting a web-based site for hosting images of certificates stamped on spray-treated wood surfaces, and other certification documents, and (ii) mobile smart-phones used to capture digital photographs and video recording of spray-treated wood-framed building sections during the on-site fire-protection spray process, and upload the captured digital images to the data center, for each spray treatment project, so that insurance companies, builders, and other stakeholders can review such on-site spray completion certifications during the building construction phase of the wood-framed building.

A cloud-based system network for managing the supply chain management operations associated with shipping clean fire inhibiting chemical (CFIC) totes from a chemical factory or warehouse to a network of lumber factories producing Class-A fire-protected lumber, and/or wood-framed building construction job sites with interior wood surfaces being spray-treated with Class-A fire protection during the construction phase. The system network includes a data center with web, application and database servers for supporting one or more mobile applications running on mobile computing devices (e.g. smart-phones and tablet computers). The mobile applications were configured for (i) scanning barcode symbols and/or RFID-tags on CFIC totes, measuring the weight of such CFIC totes at the chemical factory and/or warehouse, capturing GPS coordinates of the CFIC totes and recording such data within the centralized supply chain management database, and also for (ii) scanning barcode symbols and/or RFID-tags on CFIC totes at the destination factory, warehouse and/or construction job site, measuring the weight of such CFIC totes, detecting GPS coordinates, comparing recorded weights, and enabling automated inventory replenishment.

In a process for the production of a flame retardant and/or strengthened fiberboard, a tailored fiberboard is charged on a processing device at first. Subsequently, a flame retardant and/or strengthening agent is applied to the top side of the fiberboard. The agent applied is sucked or pressed into the fiberboard. This is achieved by generating a pressure difference between the top side and bottom side of the fiberboard.

The present invention relates to a method for continuous acetylation of wood elements. The acetylation is conducted with an acetylation medium at a pressure of at least 1.5 barg in a substantially oxygen free environment. Alternatively, the method according to the invention comprises the steps of: (a) feeding wood elements in a substantially oxygen free environment to a continuous acetylation reactor, and (b) treating the wood elements with an acetylation medium in the continuous acetylation reactor under wood acetylation reaction conditions, at a pressure of at least 1.5 barg.

The process according to the present invention allows to acetylate wood elements to a high acetyl content in a very efficient way, without compromising on the quality of the material. The acetylated wood elements can be used in the production of medium density fibreboards with superior qualities such as dimensional stability and durability.
