In order to improve the quality of ADC12 alloy billets prepared by Chips Solid Pressing (CSP) process, the effects of pressing temperature, pressure and packing time on the density of ADC12 alloy billets were investigated by using the orthogonal array and multiple nonlinear regression analysis. The results indicated that the pressing temperature has the greatest effect on the density of the billets, and it is followed by pressing pressure and packing time. The optimized process parameters, including a pressing temperature of 250oC, pressing pressure of 640MPa and packing time of 45 seconds, can be used to obtain the most compact billets of ADC12 alloy prepared by CSP process.

The use of agricultural residues for particleboard manufacturing increases their value-add and help meet the growing demand of raw materials for the panel industry. Accordingly, the aim of this study was to assess the quality of particleboards produced only with sugarcane bagasse or along with Pinus and Eucalyptus wood. The experimental design consisted of 5 treatments: T1) Eucalyptus panels, T2) Pinus panels, T3) sugarcane bagasse panels, T4) 50% Eucalyptus and 50% sugarcane bagasse panels, and T5) 50% Pinus and 50% of sugarcane bagasse panels. For each treatment, three panels were produced using 8% urea-formaldehyde adhesive, with 0.65 g/cm3 apparent density, 160°C pressing temperature, 4 MPa pressure, and 8 min of pressing time. The analyses revealed that use of sugarcane bagasse for particleboard manufacturing resulted in improved water absorption and thickness swelling properties after 2 h of immersion in water. In addition, the panels produced with bagasse only showed significant reductions in the mechanical properties. However, the use of sugarcane bagasse along with Pinus or Eucalyptus wood allowed the manufactured panels to meet all the conditions required by the CS 236-66 [1], ANSI A208.1 [2], and EN 312 [3] standards.

This essay has applied 6 kinds of different materials, studied the impact of white mice’s growth and their organ development in the feeding boxes which are made of 6 kinds of different materials, such as red-pine plain board, red-pine painted board, veneer particle board, ordinary particle board, formaldehyde painted particle board, and plastic. Discover the indoor microenvironment to be fit for the growth of white mice through dissection, determination and comparative analysis of organ weights. The result indicates that white mice are living in the feeding box made of red-pine plain board whose cardiac index is the highest, the index is in the middle for the one living in the veneer particle board and plastic feeding box, the index is lower for the one living in the red-pine box with painted alkyd varnish and ordinary particle board, and the lowest one is living in the particle board box brushed with formaldehyde; The measured value of white mice’s lungs is highest in the red-pine box. It takes second place in the veneer particle board box, others are in the middle, and the lowest one is in the box brushed with formaldehyde; white mice’s liver index is highest in the red-pine box with painted alkyd varnish, it takes second place in red-pine box without painting, and it is the lowest in the ordinary particle board box and particle board box brushed with formaldehyde; white mice’s thymus index is the highest in the plastic box, it is relatively higher in red-pine box and the red-pine box painted with alkyd varnish, and it is the lowest in the particle board box brushed with formaldehyde; white mice’s kidney index (two kidneys) is the highest in the red-pine box with painted alkyd varnish, and it is the lowest in the particle board box brushed with formaldehyde. This shows that wooden environment has the positive effect on feeding white mice. Rooms in homes are the major place for Man’s living and working. Human beings could spend 2/3 of the whole life in the indoor environment. Along with the social progress, economic development, enhanced living standard, and constantly pursuing the quality of life, people are more and more concerned with the structure of living and working space. Rooms are not merely a shelter from the storm, and the more important is to provide a better working and learning environment as well as a comfortable rest place. Therefore, the quality of the indoor environment is influencing Man’s work and study directly. It concerns Man’s survival and health. Research of the relationships between indoor environment and Man’s survival and health, especially studying the impacts of indoor environment on health of growth and breeding, is increasingly becoming a topic not to be ignored [1].

In this paper, TVOC emission of veneered wood-based panel and coating processing was systematically discussed. The results showed that resin content and hot-pressing temperature of veneered wood-based particle board had obvious impact on TVOC releasing. When velocity of flow was 0.02 m/s, after 10 hours experiment, TVOC concentration in the environment chamber was 263μg/m3. While velocity of flow 0.04m/s, TVOC concentration was 29 μg/m3. High-flow velocity was helpful for rapid dissemination of TVOC. The research also found after 10 hours experiment, concentration of TVOC in environment chamber is 31μg/m3, 220μg/m3 and 400μg/m3 corresponding amount of paint was 20g, 40g and 60g. The thicker the layer was, the longer the time of layer dehumidification and TVOC diffusion needed.

Wood is the most used basic material for daily life, such as material construction, furniture, appliances, and etcetera. This causes the increase of the necessity of wood in the other hand, the availability of wood are decrasing. On of the solutions for this problem is the particle-board from the agriculture waste which is sago. One of the sago parts which can be used is the sago bark. It contains more number of cellulose and lignin then dago dregs and it also contains bigger cellulose and lignin than woods, so it can be used as particle-board. The fibers used are 5 cm, 10 cm, and 15 cm. The citterate solution concentrate is 20% which was mixed with the particle-board. These particle mixtures were in an oven in 24 hours. The production of particle-board with the target of density 0,6 g/cm2 and forged in 1800 C within 15 minutes. The aim of this research is to find out the size of fibers for the particle-board. The best quality of particle board based on JIS 5908 standard is on the 10 cm fiber , with board mechanical characteristic  : the flexibility module 22801,8196 kgf/cm2, the fracture module 334,9006 kgf/cm2, and the screw holding strength 46,5448 kgf/cm2. The physical characteristic of water concentrate 10,6249 % and the water absorption 66,8314 %. The score of dense/thickness development and internal bonding did not quality JIS 5908 A (2008). In general, the result of the research showed that longer the size of fibers the better the quality would be produced. Keywords : fiber size, oven duration, particle-board, sago bark

The purpose of this research is to get the physical and mechanical value of standard on composite board based on SNI03-2105-2006The research method is by taking the comparison of banana fiber reinforcing material (SBP) and coco fiber (SSK) in the form of particle size with composition ie (a) SBP 0%: SKK 100% (b) SBP 50%: SKK 50%, (c) SBP 80%: SSK 20, (d) SBP 60%: SSK 40%, (e) SBP 40%: SSK 60%, (f) SBP 20%: SKK 80%, and (g) SBP 100%: SSK 0%.All composite boards consist of 70 % Matrix and 30% fiber. The result of physical properties for density (ρ) ranges from 0.54 gr / cm3 - 0.75 gr / cm3 and for water content (KA) ranges from 10.5% - 13.9%.As for the mechanical properties of the value of modulus rupture (MOR) ranged between 3483.44 kgf / cm2 - 7472,30 kgf / cm2 and elastic modulus value (MOE) ranged between 15981.23 kgf / cm2 - 27243,74 kgf / cm2. Based on the analysis of tredline graphs, both for physical and mechanical properties, it turns out for each composition of natural fibers to give different values.This means that the composition of the SSK-SBP mixture has an influence on the physical properties as well as the mechanical properties of the composite board. The quality of natural fiber-based composite board (SSK and SBP) both physical and mechanical properties have been in accordance with the standard reference SNI 03-02105-2006.
