A review of thickness swelling in particleboard

Wood Science and Technology, 1970
This paper reviews the literature on thickness swelling of particleboard. Thickness swelling is directly affected by many process variables, but interactions between variables can change basic behavior. Durability depends on low swelling and a high resin content is the best way to control thickness swelling on the basis of past work.

Moisture absorption and thickness swelling behaviour of luffa fibre/epoxy composite

Journal of Reinforced Plastics and Composites, 2019
The present work aims to study the moisture uptake and thickness swelling behaviour and its effect on tensile and flexural properties of Luffa cylindrica epoxy composite. Characterizations of the luffa fibre surface were carried out by energy-dispersive X-ray spectroscopy and Fourier transform infrared spectroscopy. Composites were casted with single,

Measurement of Changes in Thickness of Compressed Cotton Samples During Swelling

Textile Research Journal, 1973
An apparatus is described for measurement of vertical dimension of cotton samples immersed in water, methanol, tiquid ammonia, and NaOH solution. Increase in thickness of cotton showed recovery from compression and swelling. The increases were automatically recorded as a function of time by a chart recorder.

Hygroscopic thickness swelling rate of composites from sawdust and recycled plastics

Wood Science and Technology, 2007
The thickness swelling rates of compression molded wood plastic composites (WPCs) prepared from 50% by weight sawdust and 50% by weight virgin and/or recycled plastics (HDPE and PP) were studied. Thickness swelling rates of the manufactured WPCs were evaluated by immersing them in water at room temperature and monitoring thickness changes for several ...

The Structure and Swelling of Corneal Scar Tissue in Penetrating Full-Thickness Wounds

Cornea, 2004
The purpose of this study was to determine corneal thickness and to examine the collagen and proteoglycans in full-thickness corneal scars up to 16 months following wounding.Ultrasound pachymetry was used to measure the depths of penetrating central scars and their surrounding areas in 16 rabbit corneas. Measurements were taken at regular intervals: 5,

Dimensional stability and irreversible thickness swell of thermally treated oriented strandboards (OSB)

European Journal of Wood and Wood Products, 2014
This paper discusses thickness swell and irreversible thickness swell properties after immersion in water for 24, 48, 96 and 168 h, changes in equilibrium moisture content (EMC) and determination of dimensional changes associated with changes in relative humidity of laboratory-made methylene diphenyl diisocyanate (MDI)-bonded oriented strandboards (OSB)

Relationship between thickness swelling and mat structures in robot-formed flakeboard mats

Holz als Roh- und Werkstoff, 2001
The relationship between thickness swelling and mat structures in robot-formed flakeboard mats under humid conditions with consideration of the density/overlaps in the flakeboard and the absorbed moisture has been studied. Results show a highly correlated linear relationship between thickness swelling and relative moisture content.

Thickness estimation of the silica-like thin layers via swelling-driven wrinkling instability

Thin Solid Films, 2020
Abstract In the present study, we report a simple, yet facile route to thickness characterization of the UV/ozone (UVO) treated polydimethylsiloxane (PDMS) thin layer via osmotically-driven wrinkling instability. Through the UVO oxidation process of PDMS, a bi-layered film with local moduli-mismatch regions (i.e., the top UVO exposed region of a thin

Contribution of wood fiber hygroexpansion to moisture induced thickness swelling of composite plates

Polymer Composites, 2009
AbstractOne of the main drawbacks of wood fiber‐based composite materials is their propensity to swell due to moisture uptake. Because the wood fibers are usually the main contributor to hygroexpansion, it is of interest to quantify the hygroexpansion coefficient of wood fibers, to compare and rank different types of fibers. This investigation outlines

Heat post-treatment to reduce thickness swelling of particleboard from fast-growing poplars

Journal of Forestry Research, 1997
According to the high thickness swelling and low dimensional stability of Poplars particleboard, this paper studied the effect of heat post-treatment on the board properties. The results indicated that the post-treatment could be a very effective way to produce dimensinaly stable fast-growing poplars particleboard.
