T/CAMA 35-2020 Modified Urea Formaldehyde Resin Adhesive Seedling Matrix Block
Basic Information
Scope
Scope: This document specifies the quality requirements, test methods, inspection rules, packaging, marking, transportation, and storage for modified urea-formaldehyde resin-bonded seedling substrate blocks. This document is applicable to the quality assessment of modified urea-formaldehyde resin-bonded substrate blocks prepared by the reaction of carbamide (urea) and aldehydes. Modified urea-formaldehyde resin-bonded composite substrate blocks and mixed substrate blocks can be implemented as reference.
