Embodiment 1

[0036] Control attached figure 1 In this embodiment, the eucalyptus finger-joined floor is composed of a plurality of finger-joined wood chips 3 which are mutually finger-joined. The finger-jointed wood chips 3 can be of various specifications and sizes, and the eucalyptus sawn timber after carbonization and moisture resurgence are sawed in different ways according to product requirements. The finger-jointed wood chip 3 is a cuboid wood block, equal in width and thickness, and has finger-shaped teeth 2 on the two short sides of the finger-joined wood chip 3, and the tooth shape of the finger-shaped teeth 2 on each finger-joined wood chip 3 is exactly the same , so two pieces of finger-jointed wood 3 can be fully engaged. A plurality of finger-joined wood chips 3 are joined to form a finger-joined strip 1, and then the finger-joined strips 1 are glued in parallel to form a finger-joined board.

Embodiment 2

[0056] S1. Log sawing: Cut the log into 1m-long wood sections, and use a band saw to cut it into slats with a width of 50mm and a thickness of 23mm;

[0057] S2. Drying: After stacking the sawed slats, place a heavy object on the top of the pile, and then use a forklift to load the eucalyptus slats into the drying kiln. When the moisture content is above 40%, the temperature in the kiln is controlled at 40°C. Humidity 92%; when the moisture content is 30-40%, the kiln temperature is controlled at 45°C, and the relative humidity is 85%; when the moisture content is 20-30%, the kiln temperature is controlled at 48°C, and the relative humidity is 75%; when the moisture content is 10 When the moisture content is less than 10%, the temperature in the kiln is controlled at 55°C and the relative humidity is 65%; when the moisture content is less than 10%, the temperature in the kiln is controlled at 60°C and the relative humidity is 35%; dry until the moisture content is below 8%.

Abstract

The invention belongs to the technical field of wood processing, and particularly discloses a manufacturing method for gum wood finger-joined floors. The manufacturing method comprises the following steps of drying, selecting, improvement of machining properties, humidifying, connection and combination, treatment of grooves and tongues, sanding, painting and the like. By using the manufacturing method for the gum wood finger-joined floors, the problems that in production of fast-growing gum wood finger-joined floors, sanding cost is high, loss of materials is high, the using amount of glue is high, tree laces crack, the moisture content of a portion between each two gum wood finger-joint floors is not uniform, finger joining is difficult, and the like are solved. The manufacturing method for the gum wood finger-joined floors has the advantages of low production cost, high product quality and the like.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a method for preparing eucalyptus finger-ground boards. Background technique [0002] Eucalyptus is one of the main fast-growing tree species in southern my country. It has the advantages of fast growth, high material hardness, beautiful patterns, and large storage capacity. However, eucalyptus also has problems such as dryness, easy cracking, deformation, long fibers, many burrs after sanding, and easy damage to knives during processing. Wood development reports on finger-jointed solid wood flooring. Therefore, the added value of fast-growing eucalyptus can be greatly increased by making finger-ground flooring. However, untreated fast-growing eucalyptus cannot produce a finger-jointed floor that meets product requirements. The main reasons are as follows: 1. Eucalyptus is a fast-growing species with fast growth, high moisture content and high growth stress...
