SHORT PROFILE RUBBER COMMODITY Classification / Classification in Commodity RubberRubber is the annual crops such as tree trunks straight. First rubber tree only grows in Brazil, South America, but after the experiment many times by Henry Wickham, a tree was successfully developed in Southeast Asia, where the plant is now developed so much until now Asia is a source of natural rubber. In Indonesia, Malaysia and Singapore began trying cultivated rubber trees in Indonesia 1876.Tanaman first rubber planted in the Bogor Botanical Gardens.Indonesia has mastered the world rubber production, but this time the position of Indonesia is constrained by two neighboring Malaysia and Thailand. More than half of the rubber used today is synthetic, but several million tons of natural rubber are still produced every year, and still is an important material for several industries including automotive and military.Botanical classification of rubber plants are as follows:Division: SpermatophytaSub Division: AngiospermaeClass: DicotyledonaeFamily: EuphorbiaceaeGenus: HeveaSpecies: Hevea brasiliensisThe recommended rubber clones Rubber Research Institute Research Centre period 1996-1998 are:· AVROS 2037· BPM 1, BPM 24, 107 BPM, 109 BPM· GT 1· PB 217, PB 235, PB 260· PR 255, PR 261, PR 300, PR 303· RRIC 100, RRIC 102, RRIC 110· RRIM 600· GGIM 712· TM 2, TM 9While some types of commonly used rubber results or processed into severalproducts include: RSS I, II RSS, RSS III, Crumb Rubber, Lump, and Latex.Using Rubber CommodityThe main result is the latex from rubber trees that can be sold or traded in the form of fresh latex, slab / coagulation, smoke or sit / sit breeze. Furthermore, the products will be used as raw material for the factory Crumb Rubber / Rubber Crumb, whoproduce a variety of raw materials for a variety of downstream industries such as tires, balls, shoes, rubber,gloves, swimsuit, rubber bands, rubber toys, and various other downstream products.The byproduct of rubber is rubber wood trees that can be derived from the garden rehabilitation or rejuvenation of old rubber plantations that are no longer producing latex. Generally the sale of rubber wood is from old rubber rejuvenation replaced with young rubber trees. Rubber wood timber can be used as building materials, firewood, charcoal, or sawn timber for household appliances. Rubber latex tapped from rubber rod be processed in the form of crepe, smoked sit and concentrated latex.· RUBBER (rubber tree)Rubber plantation is a plant that grows in many areas of theIndonesia. Rubber is a product of the clotting process latex rubber (latex).Normal rubber trees are tapped in year 5. Products from subsequent latex clumpingprocessed to produce rubber sheet (sheet), blocks (boxes), or rubber crumb (crumbrubber), which is the raw material rubber industry. Exports of rubber from Indonesia in variousshape, in the form of industrial raw materials (sheet, crumb rubber, SIR) and the productderivatives such as tires, parts, and so on.· Concentrated latexConcentrated latex is a processed product that is made of natural latex with a particular process. Concentration of natural latex is done by using four methods: centrifugation, pendadihan, evaporation, and elektrodekantasi. Among the four ways the centrifugation andpendadihan a way that has been developed commercially for a long time. Latex concentration by centrifugation carried out using high-speed centrifuges6000-7000 rpm. Latex inserted into centrifuges (separator) will experienceplayback of the centripetal force and centrifugal force. The centrifugal force is much moregreater than the acceleration of gravity and motion resulting in a separation of brownrubber particles with serum. Part serum that has a large density will be thrownto the exterior (latex skim) and rubber particles will accumulate at the center of centrifuges. Concentrated latex contains 60% dry rubber, latex skimnya while stillDRC contains between 3-8% with approximately 1.02 g/cm3 density.Latex concentration by pendadihan pendadih require materials such as sodium or ammonium alginate, gum tragacant, cellulosa methyl, carboxy methylcellulosa and flour iles-iles. Pendadih presence of lead rubber particles will form chains into droplets with a diameter larger. The difference in density between the grains of rubber and rubber serum causes the particles that have a density less than the serum will move upwards to form layers, while the under is serum.The resulting quality latex determined by ASTM and ISO specifications.According to ASTM concentrated latex was divided into 3 types based on system preservation andproduction method are:· Type I: Latex centrifuge with concentrated ammonia alone or with preservative preservative formaldehyde followed by ammonia.· Type II: pendadihan concentrated latex preserved with ammonia only or by preservative formaldehyde followed by ammonia.· Type III: centrifuge latex preserved with low ammonia levels and secondary preservatives.· CRUMB RUBBERCrumb rubber is a process of dry rubber processing through phase peremahan. The raw material comes from the latex is processed into a coagulum and of the lump. The raw material is the most dominant lump as crumb rubber processing aims to raise the degree of low-grade raw materials into products of higher quality.
Crumb Rubber processing stage include:
Composition that have undergone completion for 10-15 days trivialized in the granulator. Peremahan aims to get the crumbs that are ready to be dried. Properties produced by peremahan is easily drained so achieve higher production capacity and maturity of a perfect crumb.
Drying Composition are superbly experienced peremahan then dried in the dryer for 3 hours. Entered into the box hair dryer 12 minutes or so, air temperature 122 ° C for the composition of raw materials and 110 ° C for the WF. Temperature of the product that comes out of the dryer below 40 ° C. Drying aims to reduce levels of water to keep it safe limit of insect attack or microbiological, and enzymatic hydrolysis. In the drying factors that can affect this result is the length of completion, crumbs height, temperature and duration of drying.
Pressing a bale-bale formation of dry rubber crumb. Materials that come out of the dryer and then weighed 35kg/bandela to be packed in SW and 33.5 kg / bale for packaging. After the product was pressed by using a bale press machine. Pressed outcome measures 60 x 30 x 17 cm.Wrapping and PackagingWrapping is intended to avoid the absorption of moisture from the environment and free of other contaminants. Once the product is pressed, and then kept on the table for sorting aluminum using pengutip. After that the product is wrapped with 0.03 mm thick transparent plastic and melting point 108 ° C. Bale that has been wrapped, then put in containers with interlocking arrangement.Sources:(Map of the main commodity sectors and the primary assessment of market opportunities as well as opportunities infestations in Indonesia)
