Description
Technical field
The present invention relates to a kind of artificial board, refer in particular to and be used for indoor and outdoor and decorate, a kind of environmental protection tea composite board material that furniture etc. use the invention still further relates to the processing method of above-mentioned composite board.
Background technology
According to incompletely statistics, even to this day the whole nation built up artificial liner enterprise reach 3000 surplus family, 2000 gross annual output amounts reach 2001.66 ten thousand steres, 1503 ten thousand steres than 1999 have increased by 498.66 ten thousand steres, growth rate is about 25%.Formed wood-based panel industry framework, continued to keep the situation of growth based on glued board, particieboard and medium-density plate.Surplus the whole nation 3000 in family's artificial board enterprise, family surplus wherein glued board enterprise has 2000 approximately, and yearly productive capacity reach 1 ten thousand stere above have only 100 surplus family, mostly be small business greatly; Private enterprise is about 1700 families, total growth 992.54 ten thousand steres in 2000.According to estimates, actual annual production has reached more than 1000 ten thousand steres, surpasses other wood-based plate kinds, accounts for about 45% of national wood-based plate total amount, and nearly 100 ten thousand stere export volumes are arranged.
Although China's wood-based panel industry at present development is very fast, it is in development, adjusting stage, compares still incompatible with China integral body industrial development level.Outstanding behaviours is aspect three.The one, unreasonable structure, with low content of technology.The glued board ratio is bigger than normal, and production and consumption accounts for 5% and 50% approximately respectively, and world's glued board ratio only is about 35%.In recent years developed country is negative growth, its reason mainly be subjected to the restriction of raw material and other products partly replace due to (as OSB), the OSB high-performance composite plate of China, inorganic adhesive wood-based plate, specific use sheet material ratio are less than normal, special thick on the low side with the thin plate ratio, non-standard breadth plate is blank, feature board such as moistureproof, fire-retardant is produced less, deep processing and new and high technology new product ratio very little (20%).The 2nd, the management of water adjustment, product percent of pass is low.Most little glued board enterprise belongs to type backward in technique, is international seventies in 20th century of level, and the product qualification rate only was 69.6% in 1998; Most particieboards and medium density fibre board (MDF) enterprise produce and managerial skills are the world level eighties, and most enterprises lack technology development capability, technician's scarcity.The 3rd, product applications is narrow, and application technology falls behind.China's furniture accounts for 79% with wood-based plate, and wood-based plate for building only accounts for about 15%; As annual less than 60 ten thousand steres (about 3%) of materials for wall; And the American-European construction wall finishing wood-based plate that is used as accounts for about 50%, Japan 〉=60%.
Wood-based plate project closely-related four problems that can bring benefits: the one, raw material supply; The 2nd, energy supply; The 3rd, capital supply (circulating fund etc.); The 4th, produce market.Wherein first is exactly raw material supply (mainly being the wood raw material supply), and this problem is the principal element of restriction China wood-based plate development.Though this problem is not too obvious at present, in not far period, will progressively display.Proposed again on the 4th national wood-based panel industry technical seminar in 2000, with regard to present practical condition, since country implemented " Tian Bao " engineering, crisis had taken place in domestic part producing line raw material supply of having built up.Make a general survey of the nearly 10 years wood-based panel industry development of China must with mistake, expectation is in the period of following 10, the wood-based panel industry production of China, except that glued board because of limit by raw material can to gradually reduce, particieboard particularly MDF still can not reach balance with present production capacity, actual production and the market demand, and its market potential is huge.Though production capacity increases and may ease up from now on, output will continue to grow steadily, to meet the need of market.The market demand increases to estimate it is the building real estate faster from now on, because with regard to Wood-based Panel Production operation both domestic and external, depends on the Application and Development of building industry substantially.Although domestic these sheet materials are mainly used in furniture manufacturing industry and interior decoration industry at present, secondly are household electrical appliances industry, none is not the development that depends on the building real estate for these industries.Therefore, the prosperity of building industry, prosperity promote the principal element of the wood-based plate market demand beyond doubt.According to realtor expert's last-period forecast, at least also sustainable 3～5 years of the exploitation temperature of China Real Estate.By that analogy, China's wood-based plate industry future 3～5 in the period of will be a development peak.
The expert points out that nowadays the situation is tense for IAQ, exceeds standard for formaldehyde especially.And abuse urine aldehyde glue is the major reason that causes the sheet material content of formaldehyde to exceed standard.A large amount of workshop-based board mills do not have unified standard when using urine aldehyde glue, but arbitrarily use.Used quilts such as the various glued boards of a large amount of urine aldehyde glue, thin plank to sell for more than ten provinces and cities such as Beijing, Tianjin, Sichuan, Chongqing.What it should be noted that abuse urine aldehyde glue is all writing printed words such as " environmental protection ", " pollution-free ", " meeting national standard fully " in remarkable position when flooring board when dispatching from the factory.Indoor formaldehyde is mainly derived from construction material, furniture, various adhesive, coating, synthetic fabric etc.Formaldehyde is strengthened sheet material hardness, insect protected, anti-corrosion function and low price because of having stronger cohesive and having, so the first-selected raw material of the used glued board of present interior decoration, core-board, medium density fibre board (MDF), particieboard are to be the Lauxite of main component with formaldehyde.The formaldehyde healthhazard mainly contains the following aspects: 1. spread effect: the main harm of formaldehyde shows as Mucocutaneous spread effect, formaldehyde is the protoplasmic poison material, energy and combined with protein, high concentration can occur the serious stimulation of respiratory tract when sucking and oedema, eye stimulate, headache.2. sensitization: skin directly contacts formaldehyde can cause allergic dermatitis, color spot, necrosis, can bring out bronchial astehma when sucking high-concentration formaldehyde.3. mutagenesis: high-concentration formaldehyde still is a kind of genotoxicity material.Animal used as test can cause rhinopharyngeal neoplasm after the laboratory sucks high-concentration formaldehyde.
The arch-criminal of room air pollution---formaldehyde has following several source:
1) adhesive self contains free formaldehyde.Adhesive contains labile bond and group, and formaldehyde is isolated in the meeting chain rupture under low pH value, climax, high humidity.
2) influence of raw material.Timber can part decompose when drying, methoxyl group chain rupture in the lignin and discharge formaldehyde.The burst size of methanal of bark is greater than solid wood.Except that seeds, the release of shaving shape PARA FORMALDEHYDE PRILLS(91,95) also influences bigger, can increase the burst size of formaldehyde as dragon spruce, and oak is just in time opposite; The sawdust artificial board formaldehyde burst size exceeds 10 times than particieboard approximately; With the particieboard that low density seeds are made, its formaldehyde emission ability is higher than the particieboard made from the high density seeds.With regard to shaving shape, size more little (being that surface area is big more), the formaldehyde emission ability is strong more.
3) influence of mask-making technology.Sheet material sandwich layer formaldehyde emission potentiality is higher, and reason is that core layer temperature is lower, and moisture content is higher, and pH value is also lower, and state of cure is poor, easily hydrolysis and produce formaldehyde; Along with the decline of raw material moisture content after the applying glue, to produce the neutralized product burst size of methanal and descend, other performances of product decrease and are unfavorable for the transmission of heat, and the burst size of methanal in the product is increased.
Where is the development of China's wood-based plate from now on? have the expert to propose following approach---
1) science technological transformation, energy-saving and cost-reducing is wanted benefit, is wanted output to science and technology.In recent years, the development of the wood-based panel industry of China is very fast, and having quickened transformation of scientific findings is the process of productivity, and many enterprises are all favored for new technology, new equipment and the new technical reform scheme of industry very much.
2) quality is the key of artificial board enterprise existence, and reducing cost, increasing the benefit is the enterprise development only way.Wherein energy-saving and cost-reducing is exactly an important channel that reduces cost, because the material consumption of Wood-based Panel Production and energy consumption account for 70%～85% of product cost.
3) environmental protection, green health are the general requirements that the consumer produces sheet material, and therefore, artificial board must be changed into to pollution-free thinking of development by high pollution from the past allows artificial board undertake the mission of administering pollution, and this is an inevitable development trend.
Summary of the invention
