Abstract:
A method of manufacturing bamboo slats of bamboo blinds comprising the steps of:slicing bamboos into 7 to 12 pieces of bamboo strips, each having a width of 18-27 mm, then peeling off barks and joints of the bamboo strips and smoothing the bamboo strips so that each of the bamboo strips having a thickness from 6 mm to 8 mm and a width of 16 mm to 24 mm; steaming the bamboo strips in a container with high pressure and high heat through 10-120 minutes for removing sugars contained in the bamboo strips: then boiling them in a boiler filled with water containing 0.3%-0.8% of NaOH for a predetermined time period, and then taking the bamboo strips out of the boiler and washing the bamboo strips; then, putting the bamboo strips to the boiler with solution of anti-insects boride and bleach detergent and boiling the bamboo strips for 2-5 hours; drying the steamed and boiled bamboo strips at a temperature of about 40-60Â° C. and making sure that the water in the bamboo strips is effectively reduced to be between 5-10% and hardness of the bamboo strips is upgraded as well; smoothing the dried bamboo strips on the whole surface for forming oblong bamboo strips having a thickness of about 4.5-7 mm and a width of about 15-21 mm; assembling a plurality of smoothed bamboo strips into a bamboo plate having a thickness of about 4.5-7 m/m and then sanding the two sides of the bamboo plates; then, applying adhesive to gaps between the bamboo plates and pressing the bamboo plate in a pressing machine under high temperature and high heat so as to form a multi-layer bamboo plate set having the thickness of 15-45 mm; and cutting vertically the multi-layer bamboo plate set into bamboo slats of a predetermined size with a thickness of 3 mm and then performing the processes of anti-moisture and anti-insects polish or wax surfaces of the bamboo slats.
