Must wooden boats use tung oil to prevent water leakage?

1, tung oil is an essential product for water leakage, anticorrosion and decoration of wood products with a long history.

* In archaeology, people only pay attention to ancient lacquerware, but ignore the long history of using tung oil in wood products older than lacquerware.

* Long before China, ancient people used tung oil as a waterproof and anticorrosive material during the construction of the large sailboat and wooden boat on which they took the first large-scale global expedition.

Colored lacquerware is made by adding dyes to tung oil. Wardrobe, desk, chair, bench, bellows, wooden vehicles and boats. Daily bamboo and wood utensils are preserved with tung oil, which is also the matrix material of modern paints.

2. Tung oil is an important industrial raw material.

* Tung oil has strong permeability and is an excellent woody plant seed oil.

* It has the characteristics of fast drying, light specific gravity, good luster, strong adhesion, heat resistance, acid resistance, alkali resistance, corrosion resistance, rust prevention and non-conductivity.

Tung oil has a wide range of uses and is the main raw material for making paints and inks.

* Tung oil is widely used as waterproof, anticorrosive and antirust coating for buildings, machinery, weapons, vehicles, ships, fishing gear and electrical appliances, and can be used to make waterproof tarpaulins, oiled paper and soap, as well as emetic and insecticides for pesticides and medicines.

3. With the support of modern technology, a large number of chemicals have been used to replace part of tung oil, but it can't completely replace tung oil in waterproof and anticorrosion of wood products.

Especially for modern furniture with big paint, cheap chemical coatings with large air pollution are widely used to paint furniture, but the permeability is far less than tung oil. After two seasons of climate change, the epidermis will burst and fall off, the wood will rot, it will not be effective in protection, and it will also cause different degrees of toxic damage to the human body.
