Influences of Treatment Methods for Sisal Stems on Properties of Sisal Fiber/Formaldehyde Resin Composites

Abstract: Sisal fiber/UF composites were made by blending sisal stems treated by alkali,coupling agents and acetic acid with UF resin synthesized by the author and molded at certain temperatureEffects of different treatment conditions by the alkali and treatment ways on the mechanical properties,wear resistance,water absorption,electrical properties and thermal performance were studied and compared with those of wood powder/UF compositesResults showed that the techniques treating sisal stems had little effect on electric properties,thermal performance and water absorption of the compositesWhen the sisal stems were treated by acetylation, the composites had higher strength and better wear resistance,and properties of sisal fiber/UF are close to those of wood powder/UF composites

Sisal 3.2 Language Structure Decomposition

Abstract: The functional programming system SFP under development at the Institute of Informatics Systems in Novosibirsk is aimed at supporting development of parallel computing applications that still offer high performance and portability. The paper describes equivalent transformations of the Sisal 3.2 programming language (based on Sisal 90) structures. These transformations are to decompose the complex language structures into more simple ones that can be directly expressed by the internal representation IR1, which is based on the intermediate form language IF1. Currently some description of similar transformations can be found in few works about Sisal 90 in the form of examples. These transformations are performed by the front-end compiler from Sisal 3.2 into IR1 and help to better understand its translation strategy. The paper also briefly describes IR1 languages.

Casein Composites as Alternative Biodegradable Polymers

Abstract: In the past few decades, research has been shifted from monolithic materials to fibre-reinforced polymeric materials. These composite materials now dominate the aerospace, leisure, automotive, construction and sporting industries. The natural fibres are biodegradable and they don’t cause any type of environmental pollution when compared with glass fibres. Fibre reinforced composites are prepared using Ecmalon 4411 resin, cobalt octate as an accelerator, methyl ethyl ketone peroxide (MEKP) as catalyst, sisal and tadi fibres. Different samples are prepared with varying number of fibres, % of casein, soaking time, % of alkali. Form hardness and tensile strengths, sisal fibres and tadi fibres reinforced composites are having high hardness compared with simple reinforced composites. The treated fibres reinforced composites with and without casein are having high hardness compared with untreated fibre reinforced composites. With an increase in the number of fibres, hardness of the composites also increased for treated and untreated fibres reinforced composites. With an increase in amount of casein, the hardness also increased for both treated and untreated fibre reinforced composites.

Method for producing liquid flower fertilizer by using sisal hemp wastewater

Abstract: The invention discloses a method for producing a liquid flower fertilizer by using sisal hemp wastewater. The fertilizer is characterized by comprising the following raw materials in parts by weight: 70-80 parts of fresh sisal hemp wastewater, 20-25 parts of inorganic fertilizer, 0.1-0.5 part of secondary elements, 0.4-0.8 part of organic acid and 0.05-0.1 part of flowering accelerant. The liquid flower fertilizer is prepared by fermenting and is produced by taking the sisal hemp processing wastewater as a main raw material, so that the wastes are changed into valuable materials, the problem of environmental pollution is solved, and the production cost is low; reasonable inorganic fertilizers and secondary element nutrients are batched, and the fertilizer also contains the flowering accelerant; and moreover, the nutritional ingredients of flowers can be rapidly supplemented, rapid growth and blossom of the flowers can be facilitated, and compared with a conventional inorganic fertilizer, the liquid flower fertilizer has the advantages that the yield increasing effect is obvious, and the economic effects are obvious.
