Embodiment Construction

[0027] The present invention firstly makes the keel of the ship with steel material, then heats and softens the made fiberglass-steel-faced bamboo laminated material, fixes it on the keel of the relay, and fixes it with screws. After mixing with tung oil, lime and hemp, twist it in the V-shaped gap of the board. It contains the following steps:

[0028] (1) Bamboo collection, bamboo age 4 to 5 years, record the location, time, quantity and personnel;

[0029] Bamboo is a natural material, and its species, site conditions, bamboo age, diameter grade, degree of bending, thickness of bamboo wall and sharpness of bamboo tubes are all different. Therefore all bamboo materials cannot be used directly without selection. However, in order to simplify the process, bamboo is judged based on whether it is qualified or not. It can be used only if the following conditions are met.

[0030] (2) Bamboo timber is visually graded, and the collected bamboo is classified according to diamete...

Abstract

A bamboo plywood for building boat with glass fiber reinforced casting surface is produced by: collecting bamboo, sorting, cutting into segments, splitting into strips, sorting the strips, making sheets, carbonating, resin-immersing, making substrates, and glass fiber reinforcing and coating on their surfaces, pressing, softening, shaping, and building boats. The produced boat are cheap, corrosion-proof, impact-resistance, lightweight, durable, and easy for production.

Description

technical field [0001] The invention belongs to a production method of fiberglass-steel-faced bamboo laminated lumber and ships. Background technique [0002] Outboard plating means the structural plating on the outboard flooded side of a ship. my country's marine fishing vessels mainly include three types of steel vessels, wooden vessels and fiberglass vessels, with a number of 200,000. The prices of steel ships and wooden ships are relatively low, but they are severely corroded by sea water, and sea oysters are seriously attached. Affects the speed of the ship and the fuel consumption. It is necessary to remove marine organisms and paint for maintenance, and the cost is relatively high. [0003] Foreign small ships are mainly fiberglass ships, which have the advantage of no marine organisms and no maintenance. But the main problem is the high cost, the cost per cubic meter of FRP is 20,000 to 30,000 yuan. During the Ninth Five-Year Plan period, our country carried out...
