Cure and durability evaluation of adhesives by torsional braid analysis (TBA) - relationship of adhesive rigidity to glueline creep at varying temperature and humidity
In 1980, Costa Rica spent the income from its coffee production entirely on the purchase of petroleum products. Fully aware of the dilema facing it, the government has placed top priority on satisfying its energy requirements from its own renewable natural resources. One means of achieving this would be the establishment of agro-industrial complexes for the industrialization of sugar cane operations to produce not only sugar but also alcohol and other cane products and of the cane acreage to support it. These other cane products will likely include panel building materials, lignin-based resins, animal feedstock and fuel. Morrison, Hershfield, Burgess and Huggins Limited (MHBH), on behalf of a group of Canadian companies, has requested financial support for a feasibility study for the integrated industrial utilization of sugar cane in Costa Rica. The members in this group of companies are prepared, and competent, to implement the capital project which the feasibility study will examine.
Many technical terms used in the Rules of the National Hardwood Lumber Association and in the hardwood lumber industry are defined and explained. The Rules themselves are explained and their application is described and illustrated in the grading of many typical boards. Guidelines are provided for edging and trimming hardwood lumber to maximize its value within the constraint of market acceptability. Separate explanations are provided for each grade, and for special board types such as boards from sweepy logs, miscut boards, tapered boards, etc. Another chapter is devoted to mill equipment, operator aids, and mill design, as they affect lumber value yield.
