Description
Technical field
The present invention relates to a kind of resistance to plate of health and its manufacture method, belong to feature wood materials manufacture field.
Background technology
Using glued board and joiner plate core as base material, ecological board is commonly called as after impregnated bond paper facing, with exempting from paint, real
Wood sense is strong, nail-holding ability is good, saw cuts out the good mechanical property such as convenient, decoration performance and environmental-protecting performance.
Ecological board is a kind of emerging interior decoration sheet material, and development was like a raging fire in 2012, and house ornamentation dress is unified greatly
The trend of exterior material, as the topmost material of interior decoration, it has accounted for 70% or so of wood-based plate surface decoration material at present.
By the development of 7 years, quality obtained steady lifting, and product line has also obtained good development.Its environmental protection grade is by most
First E1 levels develop into E0 grades, while have developed the functional ecological plate such as purifying formaldehyde function, anion function, its pattern
Exploitation it is even more too numerous to mention.Although ecological board quickly grows, but it does not have formal national standard or professional standard also at present,
Market lacks supervision, causes product quality uneven.
The resistance to cracking in surface refers to the ability that product surface is kept its surface that blind crack does not occur by the effect such as wet, hot.
Surface crack resistance can be the adaptability for weighing ecological board in the case where temperature, humidity etc. drastically change.National climate difference is larger,
Southern climates moistening is warm, and boreal climate dries cold, and the difference of weather and the difference of use environment will make to ecological board
Impacted with the life-span, the ecological board used in the north there can be high requirement to its surface crack resistance.It is many raw in south
The ecological board of production will produce the phenomenon of surface checking in northern utilization, and region limitation is very big, and the popularization to ecological board is brought
Certain difficulty.Ecological board surface checking is the quality problems that current northern market is mainly complained, and is the general character of ecological board industry
Problem.
Restricted problem is used to solve the region of ecological board, research and development are applied to the freedom from cracking used under northern floor heating environment
Ecological board is extremely urgent.
