关于发展中密度纤维板二次加工的一些看法 总被引:1,自引:0,他引:1
改革开放以来,我国的中密度纤维板(简称MDF)生产得以迅猛发展。这种发展势态在一定程度上说明了国人对MDF有了更深的了解,同时也表明市场对MDF有一定的需求。另外福州人造板厂的MDF生产带来的经济效益也产生了很大的影响,很多企业纷纷效仿企求获得同样的经济效益。但是与MDF并存的人造板产品,如胶合板、刨花板、走向刨花板、竹材胶合板等产量也在不断地增加,MDF除生产企业之间的竞争之外,其厚板将与厚胶合板、刨花板、定向刨花板、竹胶合板争夺市场,其薄板将与硬质纤维板、薄胶合板、薄型刨花板争夺市场。可以想象二、三年… 相似文献

为解决普通脲醛(UF)树脂对芦苇材料胶合性能差的问题,以聚乙烯醇/三聚氰胺改性脲醛(PVA/MUF)树脂为胶黏剂制备芦苇刨花板。通过正交试验,研究密度、热压温度、热压时间、施胶量等因素对板材内结合强度(IB)、静曲强度(MOR)以及2 h吸水厚度膨胀率(TS)的影响。结果表明:芦苇刨花板的优化制备工艺为:密度0.85 g/cm3、热压温度160℃、热压时间5 min、施胶量12%。所制得的芦苇刨花板IB和MOR分别为1.00 MPa和21.4 MPa,与木材刨花板相当。未来,使用PVA/MUF树脂改性胶黏剂制备的芦苇刨花板有望替代传统木材刨花板。 相似文献

The balance of strength between the flange and web parts of veneer strand flanged I-beam was investigated by the following
methods: (1) use of different web material types, such as plywood, oriented strand board (OSB), particleboard (PB), and medium
density fiberboard (MDF), that have different strength properties; and (2) fabrication of I-beams with low-density flanges
using low-density strands with PB web material. Replacing PB or MDF with plywood showed slight significant improvement in
the modulus of rupture but not in the modulus of elasticity of the entire I-beam. However, PB and MDF showed competent performance
in comparison with OSB, thus strengthening the promising future of the use of PB or MDF as web material to fabricate I-beams.
Hot-pressing conditions used for I-beam production exerted slightly adverse effects on the bending properties of PB, but not
on MDF, OSB, and plywood web materials. The flange density of 0.60 g/cm3 was considered to be the lower limit that provides I-beams with balanced mechanical properties and dimensional stability. 相似文献

China is one of the major production countries forwood-based panel products, and its production wasranked in the second place in the world in 2003. Onthe other hand, however, China is also a country withshortage of forest resources. As the main raw material,wood supply is becoming a serious problem with thefast growing of panel production. Fortunately, thereare plenty of agricultural residues in China, and thisgives the possibility to use agri-based fibers instead ofwood. Many wood-based pane… 相似文献

The effects of thermo-mechanical refining conditions on the properties of medium density fiberboard (MDF) made from black
spruce (Picea mariana) bark were evaluated. The bark chips were refined in the MDF pilot plant of Forintek Canada Corporation under nine different
refining conditions in which preheating retention time was adjusted from 3 to 5 to 7 min and steam pressure was set at either
0.6, 0.9 or 1.2 MPa. The resulting bark fibers were blended with 12% UF resin (based on oven-dry fiber weight) using a mechanical
blender. The resinated fibers were manually formed into fiber mats and hot-pressed into MDF panels using consistent parameters.
Two panels for each refining condition were produced, resulting in a total of 18 panels. Analysis of variance (ANOVA) was
used to analyze the significance of factors. Regression coefficients and 3D contour plots were used to quantify the relationship
between panel properties and the two test factors. The results from this study indicated that the preheating retention time
was a significant factor for both modulus of rupture (MOR) and modulus of elasticity (MOE), the steam pressure was a significant
factor for internal bond strength (IB), MOR and MOE, whereas both factors were insignificant for thickness swelling, water
absorption and linear expansion. The properties of MDF panels were quadratic functions of retention time and steam pressure.
Compared to the ANSI standard for 120-grade MDF, most panels with a nominal density of 950 kg/m3 had very high IB (>1 MPa) and acceptable MOR, MOE and dimension stabilities. These results suggest that black spruce bark
residues can be considered as a potentially suitable raw material for manufacturing MDF products. 相似文献

Selecting the optimum location with attention to conditions and restrictions is one of the most importantfactors in establishing a manufacturing plant. Identification of effective criteria is an important stage in the selection for the location of industrial units. In this study, an analytic hierarchy process (AHP) was applied to select the most effective criteria for the location of MDF (medium density fiberboard) industry in Mazandaran Province, Iran. A consideration in ttaining this goal is that Mazandaran is favored over other provinces because of its resources of raw lignocellulosic ma- erial required for wood and paper industries. The results indicate that the criterion of "materials and products" and the ub-criterion of "reliability of supply of raw material" are the most important factors. 相似文献
