Description
Technical field
The present invention relates to furniture processing technology field, be specifically related to antibacterial damage resistant furniture of a kind of children and preparation method thereof.
Background technology
The world today, due to regionalization, grouping of the world economy expanding economy, trade war is day by day fierce, makes national governments and export enterprise recognize the sense of urgency of improving the quality of products all deeply, and the competition of quality product has become the most important factor of trade war.
As everyone knows, China has become one of important in the world Furniture manufacturing base, and be also an important consumption big country, can China furniture industry keep the occupation rate of domestic market, open up new world market, is a stern challenge concerning upholstery simultaneously.Will win victory in challenge, only improve the quality of products, quality is the life of enterprise.The international competition of Future Society is the competition of knowledge, information, manpower, and the net result of these competitions is exactly the quality in order to improve product, there is quality just can create famous brand name, just can seize the vitality that market, market, just meeting are profitable, just have enterprise.
The quality condition of China's upholstery, can say compared with several years ago, China's furniture quality is greatly improved, and a lot of enterprise all recognizes that quality is all of enterprise, does not have quality enterprise just not have market.But from quality product, environmental protection aspect, domestic client more trusts imported product, this illustrates that domestic furniture is compared with International Furniture, also has a certain distance qualitatively.The annual export amount of more than tens, 100 hundred million of China's upholstery is all the main contributor using cheap labor force as outlet mostly, instead of to resemble what lean on Haier's electrical equipment be the product of high-quality.This outlet does not have competitive power.The furniture quality selective examination that nearest Liaoning is carried out, spot-check 153 batch products, wherein 48 batch products are qualified, and qualified degree is only 31.4% (comprise and measure objectionable impurities), result is troubling, and quality product meets the demands far away, and how such product is in the face of international competition.
Plate fitment refers to and is main base material with wood-based plate, take plate as the assembling-disassembling furniture of basic structure.Common artificial board has glued board, core-board, shaving board, medium density fibre board (MDF) etc.Glued board (clamping plate) is usually used in making the diastrophic furniture of needs; Core-board performance affects by board core material matter sometimes; Shaving board (being again particle board, bagasse board) material is loosened, only for low-grade furniture.That cost performance is high, the most the most frequently used is medium density fibre board (MDF) (MDF).The common finishing material of plate fitment has veneer (be commonly called as and paste wooden skin), woodgrained paper (being commonly called as paster), PVC offset plate, polyester lacquer painting (being commonly called as baking vanish) etc.
Medium density fibre board (MDF) be by timber or vegetable fibre through mechanical separation and chemical treatment means, mix tackiness agent and water-resisting agent etc., then through a kind of artificial board that high temperature, high-pressure molding are made, be make the ideal artificial board of furniture.The structural rate natural timber of medium density fibre board (MDF) is even, and it also avoid rotten, the problem such as to damage by worms, its swell-shrink characteristic is little simultaneously, is convenient to processing.Due to medium density fibre board (MDF) surfacing, be easy to paste various facing, finished product furniture can be made more attractive in appearance.In flexural strength and shock strength, be all better than shaving board.
The inferior sound development that seriously govern upholstery of furniture quality, weaken furniture competitive power in the international market, result in the waste of resource and the low of economic benefit, a lot of bad product is had to be produced, flow to market, bad product cost accounts for the ratio brought a high price usually, shows that it accounts for about 30% of price according to related data research.This financial loss caused due to quality problems is huge, and some foreign scholars estimate that the loss caused because of quality problems every year in the whole world is about about 5%.And the productivity of our upholstery is far below the product of domestic other industry, as electronic product, simultaneously also lower than Hesperian productivity, so the mass loss of upholstery is much larger than 5%.Liaoning Province's furniture item quality selective examination above also illustrates this problem.This means that upholstery is while flourish, is also producing a large amount of bad products, is causing the low one of the main reasons of this quality level to be exactly that Furniture manufacture Process Quality Monitoring is ineffective, lack necessary Quality Control means.Cause too much waster to produce, repair rate remains high.
The present invention is intended to according to standard, by the analysis to operation, research, and test, experiment, data analysis, finds the principal element affecting process quality, by process relativity in optimum regime, determine its suitable index, best technological specification, produces the antibacterial damage resistant furniture of children.
