Types Of Preservative Wood
Sep 29, 2020
There are many kinds of anticorrosive wood, for example, the most commonly used is the anticorrosive wood of camphor pine, Southern pine, Douglas pine, Eucalyptus, pineapple case and so on.
1) Russian Camphor pine
Russian Camphor pine can be directly used for the full section anti-corrosion treatment by high-pressure penetration, its excellent mechanical performance and beautiful texture is recommended by designers and engineers.
Russian Camphor pine anticorrosion material has a wide range of applications, such as wooden trestle road, pavilion courtyard platform, pavilion and pavilion, waterside corridor, flower shelf fence, walkway dock, children's play area, flower table, dustbin, outdoor furniture, outdoor environment, hydrophilic environment, indoor and external structure can be used.
Due to its unique anticorrosion technology, all architectural works can be preserved for a long time.
2) Nordic red pine
European red pine of high quality, after special antiseptic treatment, has the function of anti-rot, anti-termite and anti-fungus.
Specially used in outdoor environment, and can be directly used in the environment with water, soil contact, is the outdoor landscape wooden floor, fence, bridge body, plank road and other wooden pieces of the preferred material.
3) Western red cedar
The western red cedar is North America's highest grade of embalmed wood.
Its superior anti-corrosion ability comes from naturally occurring alcohols called Thujaplicins;
An extractable acid in the red cedar called Thujic ensures that the wood is protected from insects and does not require artificial preservations or pressure treatments.
Red cedar has excellent stability, long service life and is not easy to be deformed.
Additional it also applies to the environment of high humidity, for example sauna room, bathroom and kitchen, use at making ambry, chest can prevent cockroach, moths.
Red cedar is popular in the global market due to its non-chemical treatment and pure natural properties.
4) Ponderosa pine (Southern Pine)
Ponderosa pine (Southern Pine) has the best strength and specific gravity, excellent nail holding power, and is the strongest western cork.
Yellow cedar treated with preservative and pressure can reach the wood core with preservative.
In the installation process can be arbitrarily cut, the section does not need to brush anticorrosive paint.
Products can be used in seawater or river water, absolutely not corrosion.
5) hemlock
Hemlock is the most elegant and widely used tree species in North America.
In terms of strength, slightly lower than ponderosa pine, more suitable for anticorrosion treatment.
The pressurized, embalmed hemlock wood is both beautiful and strong, rivaling the naturally durable North American red cedar.
Hemlock can maintain a stable shape and size, no shrinkage, expansion, warping or distortion, and resistant to sunburn.
Almost all wood blackens after prolonged exposure to the sun, but hemlocks retain the same color as when sawed off throughout the year.
Hemlock has a strong nail grip and excellent adhesion properties, can accept a variety of surface coatings, and very wear resistant, is suitable for outdoor use in a variety of economic wood.
6) carbonized wood
Charring wood is applied in does not contain any chemical agent under the condition of high temperature to homogeneous coking processing of wood, the wood surface with a dark brown and beautiful effect, and has antisepsis and resistance to the effect of biological invasion, the moisture content is low, not bibulous, material stability, deformation, full skim not fat, good insulation performance, simple construction, convenient besmear to brush, no special smell, is the ideal indoor and sauna materials, as a new fashion trend sanitary ware decoration;
Its anti - decay, anti - moth, anti - deformation and cracking, high temperature resistance has also become an ideal outdoor pool landscape material.
7) willow eucalyptus wood
The total length is divided into two types: Eucalyptus tereticorrhizus and Eucalyptus tamarisus.
Eucalyptus, evergreen tree, tall and straight trunk, thick wood structure, straight texture or inclined cross, easy to dry and process, and nail, paint, adhesive performance are good;
Eucalyptus tamarisk, wood texture is also like eucalyptus tereticornis, after the cut pattern is beautiful, but more difficult to dry and process.
There was little warping and cracking of Eucalyptus urophylla during drying.
Liuan wood system is hard, brown eye, fiber, elasticity, changeability.
On August 9, Shanghai Municipal Bureau of Quality Supervision organized the 2013 Shanghai Conference on quality analysis of Anticorrosive wood products.
Conference on the production of anticorrosive wood products quality supervision and spot check of Shanghai as a result, in view of the sapwood in selectiving examination found that penetration rate and amount of active ingredients to maintain and grade of using the environment does not accord with a standard to ask, the city wood products quality inspection experts from stable cross on the relevant product standard, and analyzes the causes of anticorrosive wood products is unqualified, and the corresponding corrective measures.
Representatives of the participating enterprises said that they should strictly implement various policies and regulations, organize production according to the standards, ensure stable and reliable product quality, and make production and operation in good faith according to law is the foundation of the enterprise.
Through the supervision of the government and the society, timely solve the quality problems found, take the initiative to prevent and eliminate product quality and safety risks, but also contribute to the industry norms and further orderly development.
Responsible persons from Shanghai anti-corrosion wood production enterprises and related district and county quality supervision bureau attended the meeting.
