The results showed that the volume expansibility of water swollen rubber increased with the increasing amounts of water-Absorbing resin, but its physical properties decreased.

The radial and tangential thickness swelling rates of compressed Chinese fir wood were determined and analyzed in different water temperature and interval.

THE EFFECTS OF ALL MAIN MANUFACTURING FACTORS ON THE THICKNESS SWELLING IN PARTICLEBOARD;

By tracking test on the different density particleboard made of Populus ussuriensis and Larix gmelini ,and the different thickness wood of Populus ussuriensis and Larix gmelini , this paper showed the thickness swelling equation of particleboard and wood are quite the same and coincide rather well with the theoretical deduction, that is TS(t)=a-b e -t/τ .

We analyzed the effects of hot pressing time,resin content,board density,and ratio of wood shavings to tobacco stems on the particleboard properties including modulus of rupture(MOR),internal bonding strength(IB)and thickness swelling rate of water absorption(TS).

Influence of thickness swelling on the quality stability of laminate floor covering;

A test study was made on the influence of water temperature on the thickness swelling of medium density fireboard (MDF).

The study was conducted to make compressed bamboo by hot compressing microwave-softened bamboo of four different ages, during which the effect of compression rate, compress temperature and compress time on thickness swelling and recovery rate from compressive deformation was analyzed through orthogonal experiments.

Synthesis and Evaluation of Water Swelling Polymer Plugging Agent

Since it has a high swelling rate but no crack and dispersion after water swelling,the composite can be used as water-swelling waterproof material.
