Currently used in the field of wood generally has three kinds: the first kind: there is no modified by itself has antiseptic function of wood, such as: cedar, Liu An, spinach Rogge, teak etc.. This kind of tree species suitable for anti-corrosion function and security function, the demand is not very high local. As in the indoor use more appropriate! In the field use will appear deformation, cracking, pedantic. 

Second: chemical anticorrosive wood: the use of chemicals through the high pressure impregnation to play the role of corrosion in the wood. The selection and more use of conifer wood, raw material contrast spongy cell structure, can make the agent more simple depth to wood surface. More conducive to impregnating agent! Common species such as: Pinus sylvestris, south pine: America South Pine by growth in southern America four tree populations (Ye Song, Ye Song, long short of Slash Pine and loblolly pine) form. The businessman's misleading, such as: some businessmen recommend some hardwoods to do anti-corrosion, the intent is to offer many businesses can progress, the profit will be much higher. But if used hardwoods anticorrosion treatment, depends on whether the agent impregnated to the specification of the depth, the real reached the anti-corrosion effect.

Anticorrosive common medicament current shopping malls in the: CCA and ACQ, many domestic CCA, foreign is more than ACQ. Due to the presence of extreme trace arsenic element in CCA, arsenic is a carcinogenic chemicals. So USA began in January 1, 2004 has stopped the use of CCA treated wood (industrial and special environment abroad).

ACQ (Alkaline Copper Quaternary) of the primary chemical composition of copper ammonium alkyl compounds. It does not contain arsenic, chromium and other chemical substances, no adverse impact on the environment. But the test proved that the ACQ as CCA safe, mutatis mutandis, easy to lose! That is to say after the rain after scouring agent will be lost, it will also affect the corrosion. The current high cost of CCA nearly 20%.

Selection of chemical anticorrosive wood chemistry soaking syrup, water wood after treatment rate is very high. Because the chemical preservative treatment of wood can not be artificially boring (the reason is: artificial drying temperature is higher, will make the chemical agent, lost about) to aqueous chemical anticorrosive wood's rate is usually 20% ~ 30%, the use of cracking, deformation is serious. Other, chemical anticorrosive wood color is green (such as is the choice of ACQ reagent, wood green after uneven), the use of natural wood lost wood grain and wood color, greatly affecting the decorative effect. Third: is carbonized wood (ultra high temperature heat treatment of wood)
