The Copyrolysis of Block Polypropylene with Particle Board and Medium Density Fiber

Penelitian ini bertujuan untuk mengetahui perlakuan bahan terbaik terhadap sifat fisis dan mekanis papan partikel. Dalam penelitian ini digunakan dua variasi perlakuan bahan, yaitu perbandingan komposisi bahan dan jumlah perekat. Variasi komposisi bahan yang digunakan antara kulit buah kakao dan ampas tebu adalah 100:0%, 75:25%, 50:50%. Kadar perekat isosianat yang digunakan adalah 12%, 14%, dan 16%. Ukuran panjang serat ampas tebu yang digunakan adalah 3 cm. Parameter yang diukur adalah kadar air, kerapatan, daya serap air, keteguhan patah, kuat tekan sejajar permukaan dan kekuatan rekat internal. Didapatkan papan partikel terbaik adalah papan partikel dengan perbandingan komposisi bahan 50:50% dengan kadar perekat 16%. Hasil penelitian menunjukkan bahwa nilai sifat fisis yang dihasilkan memenuhi standar JIS A 5908 (2003), SNI 03-2105-2006, dan FAO (1996). Namun pada pengujian sifat mekanis terdapat beberapa nilai MOR papan partikel yang tidak memenuhi standar. Berdasarkan persentase densitas papan partikel maka papan partikel yang dihasilkan termasuk jenis medium density particle board hingga high density particle board.Kata kunci: kulit buah kakao, ampas tebu, perekat isosianat, papan partikel

Abstract The proper parameters of sanding with abrasive sanding machine are significant to reduce energy consumption and to improve processing efficiency and quality. The parameters sanding speed, feed speed, and granularity have been investigated in terms of the sanding force (sF) and normal force (nF) for particle board (PB) and medium-density fiberboard (MDF). For PB, the sF and nF show decreasing trends of second power with increasing sanding speed and linear increase when feed speed increases. The sF and nF are almost constant when granularity increases from 40 to 80, but these forces show increasing trends of second power when granularity increases from 80 to 150. For MDF, the sF and nF change as trends of second power with increasing sanding speed and increase in trends of second power with increasing feed speed. The sF and nF force decrease when granularity increases from 40 to 80, but these forces present linear increasing trends when granularity increases from 80 to 150.

Shavings rattan waste from the rattan industry can be made into particle board which the addition of glue and hot pressing. The various of the particle length compositions are, 100% of 1cm of size, mixture of 1cm and 3cm (50%,50%), 1cm and 5 cm (50%, 50%), 3 cm (100%), 3 cm and 5 cm (50%, 50%), and 5 cm (100%). Each of combination was added by 6% and 12% concentration of urea formaldehide glue (UF). All of the physical and mechanical test results are fulfil the Indonesian Standard of particle board (SNI.03-2105-2006). Those results are water content 12,36 – 12,49%, thickness increase value 12,25 – 14,15%, density 0,56 – 0,69 g/cm3, hardness 83 – 155 kg/cm2, broken strenght (MOR) 115 – 1306 kg/cm2, bending strenght (MOE) 547 – 6917 kg/cm2, The best result for Particle was shown in and 6% of the glue addition. The particle boards are classified as medium density board class which has 0,40 – 0,80 g/cm3 of density. Base on the density chriteria and the glue, the particle board can be use for parts of interior material such as cabinets, desks, bookcase, and etc. Key wood : particle board, rattan waste

Mechanical And Physical Properties

The objective of this study is to determine the mechanical and physical properties of Particleboard made from modified particle of Kelampayan (Neolamarckia cadamba). The particles were modified with Silane and Sodium Hydroxide (NaOH) by soaked the particle for 24 hours with different ratio ( Kelampayan + Silane, Kelampayan + NaOH, and Kelampayan + Silane + NaOH). The result showed that the mechanical and dimensional stability of the treated wood were improved. Particleboard made from 0.8 mesh particles treated with Silane and NaOH were highest value of bending strength modulus of rapture (MOR) 22.89MPa, modulus of elasticity (MOE) 3916.88MPa and Internal Bond properties 0.48214 MPa whereby particleboard made from 0.5 mesh particles treated by Silane were highest value for bending strength (MOR) 15.75MPa, MOE 2905.34 and Internal Bond properties 0.5748MPa.Outcome of this proposed research will provided valuable databases to the wood based industry to use Kelampayan as an alternative raw material in their down streams production such as particleboard, medium-density board and chipboard manufacturing.

. In an effort to maximize the increase in economic value nipah plants, it is used to produce sugar, there also needs to be innovations that make nipah plants into high-value products, including the utilization of palm fiber for raw material for making particle boards. The objectives to be achieved in this research are Analyzing the mechanical properties of particle boards from palm oil with polyester resin adhesive. Particle board raw material used for palm fiber, The adhesive used is polyester resin by comparison A = 1:7, B = 1:8, C = 1:9. Static analysis of the data used is a completely randomized design (CRD) with three levels of treatment and three replications so the total number of trials is nine. The resulting density value includes medium density. Value of the resulting density in the treatment A (1:7), B (1:8), C (1:9) successively produce 0,78 gr/cm³, 0,69 gr/cm³, 0,62 gr/cm³. The average value of Modulus of Elasticity (MoE) The resulting effect is not real and does not meet SNI 03-2105-2006 min 20.400 kg/cm² except in the treatment A2, A3, B1, B3 that meets the standards SNI, Modulus of Rupture (MoR) The result has no real effect and the value produced meets SNI 03-2105-2006 for all treatments that require a minimum 82 kg/cm² in all treatments.Keywords: Particle Board; SNI 03-2105-2006; Polyester Resin; MoE; MoR
