What Are The Characteristics Of Hardwood And Softwood

Hardwood pyrolysis gives smaller amounts of char in the pp stage than softwood pyrolysis which is observable even for demineralized wood samples.

What are the characteristics of hardwood and softwood.

The following characteristics of softwood and hardwood pyrolysis in a closed ampoule reactor n 2 600 c 40 600 s were identified by using 10 wood species. Less dense strait fiber is found. Their growth rate is faster than hardwood. Softwood trees are known as a gymnosperm.

Although sometimes old needles fall off the softwood tree branches are always covered with needles. Hardwood comes from deciduous trees with broad leaves that shed their leaves during portions of the year while softwood comes from conifers that remain green throughout the year and have needles instead of leaves. Hardwoods are deciduous trees such as oak elm and birch whereas softwoods are evergreens such as spruce pine and fir. They are basically angiosperms.

Hardwood and softwood both are hard. As their name implies hardwoods are generally harder and stronger than softwoods. Most softwood have a lower density than hardwood weighs lower. In general hardwood comes from a deciduous tree which loses its leaves annually and softwood comes from a conifer which usually remains evergreen.

Softwood trees do not have broad leaves but rather have needle like leaves. This means that the leaves fall off in autumn and the tree remains leafless through springtime. On the other hand softwood conifers do not pass the winter with bare branches. In terms of price they are often less expensive than hardwood.

Hardwood has a slower growth rate. Softwoods tend to keep their needles throughout the year. Softwood is collected from conifer trees which are evergreen having needle shaped leaves. Hardwoods shed their leaves over a period of time in autumn and winter.

Hardwood and softwood both contain parenchyma and tracheids. These are generally gymnosperms. Please read more on density here. Most do not shed their needle like leaves during the year.

They are generally evergreen meaning that they do not shed their leaves in the fall and do not become dormant during winter. Hardwood and softwood both are secondary xylem. For example the bending strength of most hardwoods is within the range 45 80 mpa whereas. The softwood larch and cypress are exceptions.

Hardwoods tend to be slower growing and are therefore usually more dense. Hardwood information specifies that hardwood trees are deciduous. Hardwood trees are also slower growing than softwood ones leading to higher prices. Softwood trees generally grow faster than hardwoods and are usually less dense.
