The installation and configuration of laboratory benches constitute an integral part of laboratory renovation and construction. For most users, the core concern is whether the quality of laboratory benches meets technical requirements. Procuring inferior products will cause considerable troubles in subsequent use. Below are the specific requirements and technical indicators for laboratory benches for reference.
Thickness Requirement of Laboratory Bench Countertop
Solid phenolic resin board thickness: ≥12.7mm
1. Chemical and Physical Properties of Materials
Random sampling and inspection shall be conducted in accordance with general test methods for wood-based panels and surfaced wood-based panels.
Graded testing shall be performed with 45 kinds of strong acid and strong alkaline chemical reagents, including sulfuric acid, acetic acid, nitric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, formaldehyde solution, sodium hypochlorite, hydrogen peroxide, ethyl acetate, magnesium oxide, ammonium hydroxide, saturated potassium dichromate solution, etc.
2. Physical Performance Indicators
Tested in accordance with the standard for high-pressure decorative laminates impregnated with thermosetting resin paper, all physical properties shall meet or exceed standard requirements:
Resistance to boiling water, dry heat resistance, contamination resistance against sodium hydroxide and hydrogen peroxide, and cigarette burn resistance all reach Grade 5 with no surface changes;
Crack resistance test (70℃, 24 hours): Grade 5 with no surface cracks;
Impact resistance (324g drop from 1m height): No surface cracks;
