Bamboo chopsticks are the most common kind of bamboo chopsticks in our daily life. Today xiaobian here for you to briefly explain the manufacturing process of bamboo products.
Usually the bamboo products from a bamboo into our bamboo products can be roughly divided into preparation, fine, manual carving, sanding, group vertical inspection sand, painting, packaging a few processes, the following is a detailed explanation of their specific role.
Preparation: choose inspection and applicable specifications bamboo 柸 panel, according to the size of the product material, blanking, extended 1.5 cm or less processing, to special-shaped products according to different shape, size and plane light light after trimming, the thickness of 0.3 mm or less makeup machining, using aqueous polymer isocyanate wood adhesive in the normal pressure (direct pressure 16 million mpa, lateral pressure 20 million mpa) temperature at 35 ℃ for dry 3 h as a whole.
Elaboration: according to the shape and size of the product, the product is processed and bent to form a shape. There is no abnormality between the shape and the sample, and the size is controlled within 1mm. Precision cutting and drilling are required to be accurate within 0.5mm. The appearance and shape of vehicle volume and copying machining shall not exceed 2-3mm as the sample size.
Manual carving: referring to the original shape, it is required to be free from burrs, knife marks, smooth and natural, of the same shape and size, bamboo products are hard and not easy to be deformed, with clear carving texture and strong three-dimensional sense.
Sanding: use 80# emery cloth to sand the coarse sand without deformation, which requires smoothness; use 150#, 180#, 240# sand in the fine sand process, which requires smoothness and naturalness; use 150#, 180#, 240# emery cloth to sand the petals of emery cloth with sanding wheel for carving products, without deformation, flat and strong three-dimensional sense.
Group set up: with AB glue assembly, iron cloth, the glue no glue phenomenon, appropriate pressure, under the condition of 30 ℃, 35 ℃ and 6 hours glue dry extract can reproduce, ensure no loose structure, strong and firm.
Test sand: corner touch scratch on product joint glue, use 180 #, 240 # emery cloth hand sand processing, smooth smooth, at 25 ℃ and 30 ℃ under the room temperature environment of preserve one’s health in 24 hours to keep the product moisture + 12 ℃ or so.
Besmear outfit: paint with bamboo grain instinctive quality is given priority to, accomplish 3 bottom 2 sides, requirement surface bamboo grain is clear and transparent strong, have burnish, smooth, feel good, wear-resisting, sculpture product is bright, stereo effect is strong.
Inspection and packaging: to ensure that the surface is free from defects, and the appearance shape and size are in line with the original sample standard. The packaging materials are made of 150-pound carton polystyrene, 18-23 kg in strength. The packaging test has passed shock test, pressure test and drop test to ensure the product quality.
After the above process, most bamboo products will become commonly used bamboo products in our daily life. Of course, some bamboo products with simple structure do not need so many steps, and some bamboo products with complex structure may need more processing.
