TH68546A - The process of unfolding bamboo - Google Patents

Abstract

DC60 Method for unfolding bamboo without cracking By soaking in water at room temperature until the bamboo is saturated, the bamboo softens by boiling it in boiling water and then immersing it in a drying oil (linseed, tangmayao, etc.) that is heated to a smoke temperature (180 - 190 degrees Celsius). While pressing for 30-60 seconds to flatten a sheet And then imported into The process of keeping the unfolded bamboo intact (not rebound) by hot pressing at the same temperature as the smoke point. Of dry oil So that the water and dry oil evaporate from the bamboo completely. And take the bamboo sheet Drying for 24 hours. Process without cracking the bamboo. By soaking the bamboo in water at room temperature until the bamboo is not saturated, then softening the bamboo by boiling in boiling water and then dipping it in dry oil (linseed, tangyao, etc.) heated to smoke temperature (180-190 ํ C). ) And press for 30-60 seconds to flatten a sheet. And then imported into The process of keeping the unfolded bamboo intact (not rebound) by hot pressing at the same temperature as the smoke point. Of dry oil So that the water and dry oil evaporate from the bamboo completely. And take the bamboo sheet Dry for 24 hours.

Claims (2)

1. The process of flattening bamboo into flat or curved sheets without cracking: 1.) Soak the bamboo halves that have been removed from the outer shell, inner surface and articulation in water at ambient temperature. Until the bamboo is already saturated with water 2.) Boil the bamboo that has been saturated with water in boiling water for at least 14 hours 3.) Soak in dry oil that is hot to the point of smoke generation is 180-190 degrees. Celsius while pressing for 30-40 seconds into a flat plate or a curved disc. 2. The process of making bamboo sheets flat or curved. Obtained from the process of claim 1 retained the shape by pressing the aforementioned bamboo plates with a hot press At a temperature equal to the smoke generation temperature of the drying oil used Until the water and oil used dry are considered to have evaporated completely Then baked at 103 plus minus 2 degrees Celsius for about 24 hours.
