Process safety of primary and secondary school desks and chairs

Primary and secondary school desks and chairs are to accompany the kids in school time. Long teaching tools, especially in primary and secondary school, children learn when almost cannot leave the tables and chairs. Furniture structure design, materials and manufacturing processes of scientific health and safety is directly related to the desk and chair. On the premise of meet the national standards, height, height of desk and chair, seat surface table headroom main design index should not be ignored, such as process safety is very important.
from a security point of view of environmental protection, primary and secondary school desks and chairs materials should be chosen without peculiar smell, formaldehyde-free emissions of high quality materials, especially the direct contact or close to the children's hands and face, respiratory system desktop.

on steel support units, in the process of use under the condition of welding interface position, all welding shall be used. The welding joint should be smooth, no burr,. No welding, spot welding and welding bad phenomenon, ensure the safety of the use and the whole stability of the primary and secondary school desks and chairs. Steel bracket after compound, need after sand blasting, polishing, degreasing, rust removal, such as pretreatment process, and then choose good environmental performance in high voltage electrostatic powder spraying, installed after high temperature curing. Need to emphasize that the electrostatic spraying process, no peculiar smell, formaldehyde emission of qualified, to ensure the safe use of primary and secondary school desks and chairs.
all in all, only in strict accordance with the requirements of national laws and regulations, and meet the requirements of clean and environmental protection, provide the good materials for primary and secondary school desks and chairs the science and technology and environmental protection. Parents and schools can rest assured that the students feel free to give the child a good learning environment, let the children healthy growth in the study!
