Fertilizer for producing trichoderma harzianum with sisal hemp residue and preparation method of same

Abstract: The invention provides a fertilizer for producing trichoderma harzianum with sisal hemp residues and a preparation method of same. The fertilizer mainly includes the following raw materials: fresh sisal hemp residues, corn bran, straw, trichoderma harzianum seed, magnesium sulfate, ammonium sulfate, calcium hydrogen phosphate and dipotassium hydrogen phosphate. The fertilizer is high in bacteria content and is low in production cost, is environment-friendly and is low in energy consumption, can improve environmental quality of soil significantly and increase the yield of corps and can prevent various diseases. Meanwhile, the sisal hemp residues, which is a waste from production factory of sisal hemp, is high-effectively employed, thereby achieving important significance to economy and environment protection in local.

Effects of adding sisal and glass fibers on the mechanical behaviour of concrete polymer

Abstract: In this study, we investigated the influence of the addition of sisal and glass fibres on the mechanical properties of polymer concrete (PC). These types of concrete are used in many modern civil engineering applications. The prismatic specimens sized according to ASTM C580-02 were elaborated with a PC constituted by 14% constant mass of polyester resin matrix, a granular skeleton based on sand and powder marble. The reinforcement with 60% sand and 26% marble powder adopted in this investigation is the best formulation found in previous authors work. This composition was reinforced by 1 and 2% of sisal and glass fibres, the first one having lengths of 6 mm or 12 mm, however, the second unidirectional cut into bands. These specimens were subjected to 3-point bending monotonic loading. The results obtained were discussed and compared with those obtained for control beams without fibres reinforcement. It is important to note that the incorporation of the glass fibre contributes to an increase of the ultimate load of the polymer composite material produced, however, the addition of the sisal fibre lead to its decreases. In addition, the incorporation of 2% of sisal fibre having 6 mm length leads to a reduction of 26% of the mass of the specimens.

Method for preparing fishing line from sisal hemp fiber and polyethylene fiber composite material

Abstract: The invention discloses a method for preparing a fishing line from a sisal hemp fiber and polyethylene fiber composite material. The method comprises the following steps: immersing sisal hemp fibers into a hydrogen peroxide solution; immersing super-high molecular weight polyethylene fibers into a potassium permanganate solution; mixing to obtain mixed fibers; quickly freezing the mixed fibers by an instant freezer, and immersing the mixed fibers with a sodium acetate solution; quickly raising the temperature to obtain the mixed fibers subjected to primary treatment; preparing a modifying solution from methyl methacrylate, isocyanate, absolute ethyl alcohol, ethylene glycol and fatty acid methyl ester ethoxylate; treating the mixed fibers, and immersing the mixed fibers into 1-butyl-3-methylimidazole tetrafluoroborate ionic liquid to obtain the modified mixed fibers; mixing the modified mixed fibers, an enhancing agent, a toughening agent, a waterproof agent and an ultraviolet absorbent, and conveying a mixture into a banbury mixer; blending, and conveying a mixture into a line production machine to prepare the fishing line. By adopting the method disclosed by the invention, the fishing line which has good toughness, high strength, good compatibility and low cost and is prepared from a fiber composite material can be obtained.
