Manufacturing process for modified sisal fiber used for plastics

Abstract: The invention provides a manufacturing process for a modified sisal fiber used for plastics. According to the invention, sisal hemp is minced and then immersed in a sodium hypochlorite solution; then amylase is added for enzymatic hydrolysis; filtration is carried out after enzymatic hydrolysis; an obtained filter residue is immersed in a diluted formaldehyde solution; a fiber modifier is added after immersion; and drying is carried out so as to obtain the modified sisal fiber. Addition of the modified sisal fiber into plastics enables toughness, antistatic performance and corrosion resistance of the plastics to be improved and an application scope of the plastics to be broadened.

Method for producing vegetable foliage fertilizer by using sisal hemp wastewater

Abstract: The invention discloses a method for producing a vegetable foliage fertilizer by using a sisal hemp wastewater The method is characterized by comprising the following raw materials in parts by weight: 80-90 parts of a fresh sisal hemp wastewater, 5-10 parts of an inorganic fertilizer, 05-10 part of microelements, 3-5 parts of organic acid, and 01-05 part of a surfactant The vegetable foliage fertilizer is prepared by fermentation, and is prepared from the wastewater after sisal hemp processing as a main raw material, so that wastes are changed into treasures; the problem of environmental pollution is also solved; the production cost is low; reasonable inorganic fertilizer and microelements are blended, so that the nutritional ingredients of vegetables can be quickly supplemented; rapid growth of the vegetables are promoted; the yield-increasing effect is increased in comparison with a conventional inorganic fertilizer; the economic benefits are significant

Production method for sisal hemp paste

Abstract: The invention discloses a production method for sisal hemp paste.The method comprises the following steps that 1, sisal residual water produced in the process of producing sisal fiber from fresh sisal hemp is collected and placed into a settling pond for settling and fermentation to obtain settling; 2, then, the settling is sucked into a sheet frame of a sheet frame machine, the suction pressure is 0.5-0.8 MPa, suction is performed continuously for 40-70 min, and water in the settling is pressed out of the sheet frame under the suction pressure; 3, air is introduced into a gap of the edge of the sheet frame, ventilation time is 30-90 min, the temperature inside the sheet frame is controlled to be 40-80 DEG C, air flows out of the sheet frame, and aired sisal hemp paste is obtained.According to the production method for sisal hemp paste, the production time is greatly shortened, the method is not affected by natural weather, the working efficiency is improved, the cost is lowered, and the sisal hemp paste produced through the method is excellent in quality.

Coir and sisal fibers as fillers in the production of eucalyptus medium density particleboards – MDP

Abstract: The aim of this study was to evaluate the potential use of sisal and coir fibers in combination with Eucalyptus particles for the production of particleboard. The particleboards were produced in three layers. The first and third layers (face) were made with small Eucalyptus particles. The second layer (core) was made with big Eucalyptus particles in combination with coir or sisal fibers. The particleboards were prepared with the substitution on Eucalyptus wood for sisal and coir fibers in the particleboards core, in doses of 0, 10, and 20%, relative to the total mass of particles. The particleboards were characterized by mechanical, physical and thermal properties. The results were not satisfactory for particleboards with sisal. However, for coir particleboards the physical-mechanical properties were very similar to those particleboards produced only with Eucalyptus. This work demonstrates the potential use of the coir that is commonly disposed in landfills on the Brazilian beaches.

Saponin-foamed and sisal fiber-enhanced wall body heat preservation mortar

Abstract: The invention discloses a saponin-foamed and sisal fiber-enhanced wall body heat preservation mortar. The mortar is prepared by the steps of raw material selection, processing and preparation of heat preservation mortar. A finished product of the heat preservation mortar is prepared by mixing expanded perlite, volcanic tuff, aluminate early strength cement, polyvinyl formal, a mixture of saponin and short sisal fibers and an organic silicon water repellent in a mass ratio, stirring and performing waterproofing packing. Pores are generated by utilizing a foaming effect of the saponin; the strength of a heat preservation layer is improved by sisal toughening; mechanical strength is improved by utilizing the volcanic tuff; therefore, the heat preservation mortar of the invention has the advantages of low thermal conductivity, high strength, high bending resistance and impact resistance, and convenient production and use, and is applicable to the thermal insulation and the heat preservation of a building wall body.
