TH4737C3 - Light-Weighted Particle Board - Google Patents

Abstract

Lightweight partition with a manufacturing process that includes: Raw material preparation The process of mixing raw materials and adhesives, spreading sheets, forming, raw materials mixed with glue. Hot pressing and conditioning steps There is a unique feature. The raw materials used in the production are weeds, vetiver, prue. The particle board obtained from the production has properties of lightness, toughness, strength and durability, suitable for indoor use. Especially used as a ceiling with strength properties. Durable close to wood Has a beautiful pattern Outstanding colors that are unique to the pattern on any type of wood and low production costs as raw materials are naturally readily available. The lightweight partition also replaces wood in the manufacturing industry. Household appliances or furniture The manufactured product or furniture is lighter and has a lower cost to manufacture than the same product or furniture made of wood.

Claims (1)

1. Production process of lightweight partition panels where such production process consists of - Raw material preparation process. The raw materials are light and durable, which are then sliced or chopped into small pieces, size 1x1 cm, and then dried at a temperature of 60-70 ° C for 1-2 hours until the humidity is in the range of 15. -20%, then crushed until the raw material is about half the size. Then the second time drying at 60-70 degrees Celsius for 1-1.5 hours until moisture is obtained. As specified in the range of 5-9% - the process of mixing raw materials and adhesives by mixing raw materials with specified moisture content with 5-9% polymerisocyanate adhesives by Weight by the amount of glue that is compared to the weight The glue is applied directly to the dry weight of the raw material and does not need to mix other ingredients or additives. Mixing of the glue with the raw material is mixed by spraying the glue with the raw material in the mixing tank. By putting raw materials in a mixing tank Rotate by manual force or electric current and apply the glue that has been weighed in a fixed amount and put on the nozzle for spray adhesive. Spray glue is sprayed by spraying polymeric isocyanate glue. Molecule Small size passes from the nozzle in the form of a glue mist. By continuously injecting glue into the raw material Want to mix with glue in the mixing tank Mixing of glue with raw materials starts by rotating the mixing drum with raw materials, the mixing tank with raw materials will slowly and continuously swirl right around itself to make the glue mixing with Raw material by spray glue is evenly When the glue is sprayed out. Will let the mixing drum rotate for another 4-6 minutes to allow the glue droplets to spread evenly throughout the material; - The process of sprinkling forming sheets, raw materials mixed with glue By using a forming block made of Material is stable. To put on the steel plate Which on top of the steel sheet is placed a material that prevents sticking. Between the steel plate and the raw material mixed with glue When finished preparing blocks for forming Therefore began to sprinkle Raw materials mixed with glue By sprinkling the raw materials mixed with glue in the same plane inside the forming block. After all the raw materials mixed with glue are sprinkled in the forming block. Therefore place materials that prevent sticking together Between the sheet and the adhesive raw material and the steel sheet that fits in the forming block. On top of the adhesive raw material in order, then the forming block is removed; - Hot pressing process. By bringing raw materials that are mixed with glue and have been sprinkled through the forming sheet The hot press at hot compression has a density in the range of 400-900 kg / m 3, using the heat temperature of 100 - 120 ° C, the compressive strength of 140-160 kg / cm3 and the time of hot pressing 3. -5 minutes; and - conditioning step. When finished the process of hot compression Take the hot pressed partition. From the hot press And placed in an area with room temperature to adjust the condition of the partition The humidity is consistent across the sheet. The partitions were placed at room temperature for a period of 6-8 days. By selecting materials that are light and durable, natural raw materials, vetiver weed, are used as materials for lightness, toughness, strength and durability.
