Cork flooring is divided into five categories as follows:
First class: cork flooring surface without any cover, this product is the earliest.
?
The second category: the cork flooring surfaces for painting. That cemented cork surface coating or UV varnish or paint photosensitive varnish PVA. According to the different kinds of paint can be divided into three types, namely high-gloss, matt light of peace. This is a 1990s technology, these products require cork flooring surface was fairly high, which is used in soft wood purer.
?
The third category: PVC veneer, PVC cover that cork flooring surface veneer, the structure is usually four layers: the surface with PVC veneer thickness of 0.45mm; the second layer of natural cork decorative layer having a thickness of 0.8mm ; third layer is cemented cork layer having a thickness of 1.8mm; the bottom is the stress balance and waterproof PVC layer, this layer is very important, the absence of this layer, in the production when the material after the thermosetting, PVC surface layer cools and contracts, the so that the entire piece of warped floor. This flooring is currently popular with consumers both Beijing and Shanghai.
?
The fourth category; PVC veneer, thickness 0.45mm; second natural veneer layer having a thickness of 0.45mm; the third layer is cemented cork, having a thickness of about 2mm; PVC plate and the third layer of the same type waterproof, while the plate plane stress balance, the thickness is about 0.2mm.
?
The fifth category: plastic cork flooring, cork flooring resin cement, rubber cork flooring.
??1, the first class of cork flooring: cork layer thicker, pure texture, surface layer is only 0.1 to 0.2 thick, thin, flexible, high strength wear-resistant layer of cork does not affect the play of the excellent performance of its wear-resistant surface the material is non-toxic, tasteless, odorless and durable, can be pre-painting, apply a pressure sensitive adhesive and covered with cork back of the release paper, the user at the factory is extremely convenient, as long as yer release paper can be directly pasted into a clean, dry The concrete floor. Such users can design their own floor, own paste, very convenient. Another finish also available in cork floor coverings after more use of this process as a whole painting, Australia and New Zealand and other countries. His shoes in the bedroom if they can not be brought into the sand, generally 10 to 15 years of life is not a problem.
??2, for shops, corridors, large flow of people is difficult to avoid the sand place, to use the second and third floor category. Its surface has a thick layer of flexible abrasion, sand pressed into the wear layer will not slip back, when the foot is off the sand particles will be ejected, will not scratch the wear surface, which is an advantage; but although the surface is non-toxic PVC, pure PVC resin can not be used as wear protection layer, it is brittle and easy to aging, and therefore in the recipe was added plasticizers, heat stabilizers, light stabilizers, antiblocking agents, antistatic agents and the like, although floor stringent requirements of these additives, non-toxic formula, but at least there is a taste of plasticizers, PVC easy to migrate to the surface, and susceptible to solvent extraction, and may accelerate aging, it is not appropriate for the bedroom pavement. At the same time these two types of glue cork layers have been excessively compressed, insulation, noise reduction, shock absorption, and other functions deteriorated. At present, the domestic consumer advocates and some foreign products, blind selection of high-priced foreign second, three categories of products, while inexpensive products made the first anti-exist numerous doubts. From a scientific point of view, it is generally PU coating life of 15 years, the first coating has more than 10 years of life should consider updating the coating, and PVC plastic aging life better than PU resin, aging decomposition after hydrochloric acid and chlorine ionic contamination, therefore, should be the preferred first class bedroom ground floor.
???3, with a rubber cork for flooring, elastic, vibration absorption, sound absorption, sound insulation performance is also very good, but usually flavored rubber, special rubber senior uneconomical, but with PU or PUA high wear-resistant coating for protection layer will be in terms of performance and price have been taken into account, because it can be used for room and indoor sports venues and concern.

??4, the bottom cementing cork or rubber mat for cork flooring is that both the use of elasticity, thermal insulation, acoustic noise and other properties of cork, but also for the construction of a wooden floor and reliable moisture barrier layer, simplifying the wood floor coverings processes. But cork material used must be waterproof and resistant to mildew. Cheapest Composite Decking
??5, the density of cork flooring products division 400 ~ 450kg / m3,450 ~ 500kg / m3 more than 500kg / m3 are three commonly used in the middle of 450 ~ 500kg / m3, if the room is not heavy, as far as possible the use of small density, because Its flexibility and better insulation, sound absorption, sound insulation, vibration absorption properties.
