การศึกษาและพัฒนาวัสดุปลูกพืชน้ำหนักเบาจากต้นกล้วยเพื่อใช้กับสวนแนวตั้ง
The study and Development Lightweight growing media by banana tree to use a Vertical garden.To create thermal comfort for building users are the main factors causing the air conditioning. The cause of the electrical consumption. Thus bringing the tree into the building. In the past the building that used tree. Create a homey Subsequently it has adopted a large tree used for the purpose of lowering the temperature of the surrounding buildings. Developed into a roof garden Reduce heat to pass through the roof. And is currently being applied in the manner of a green wall. This helps reduce the heat that enters the building through the building envelope as well. The behavior of the tree to absorb water from the roots to the leaves and then passed to photosynthesis. Such a process makes the water evaporates and the air has been cooled by the surrounding trees The Heat pulled away for the evaporation of water. Such a process which happens from time to time no matter how much humidity in the air. The cool environment is another factor that manipulates the ambient environment to environment and buildings The benefits of trees in the green areas of the city this is helping to reduce and prevent the phenomenon of urban heat island The study and Development Lightweight growing media by banana tree to use a Vertical To reduce the weight of structural data were collected to design the plant material. Then the data from design professionals and vertical landscaping questionnaire. And interviews to analyze the result. And amends To test plant material vegetation series of 12 trials by planting vegetation. On the wall a series of three experiments wall. (Width 1.20 m. Height 3.00 m.) Of the test data and the growth of vegetation. Found that plants grow well on a series of plant material. The unit is lightweight and planting is not burdened with the weight of the building structure.
การเตรียมกระดาษคราฟท์จากผักตบชวา ใบสับปะรด และกาบกล้วย
This research had a main purpose for studying the utilization of water hyacinth as the key component of paper production mixed with the agricultural waste as pineapple leaves and leaf sheath of banana tree. The paper pulps were prepared from 5 g/l NaOH at 90-95oC for 3 hours then bleaching with 5 g/l Hydrogen peroxide at 90-95oC for 30 minutes. The whole pulps were detached improvement with 5g/l Acramine 3187 before paper establishment production. Finally the strength of obtaining papers was consideration and competition to any craft paper type. As the results the appropriate ratio of paper was 70% water hyacinth (stem) 10% pineapple leaves and 20% leaf sheath of banana tree. It had 31.19 kN/m2 for bursting strength tearing strength as 309.17 mN and 0.49 mm thickness. The basis weight was 183±5 g/m2. The achieved paper was equivalent as KI craft paper. It was presented for packaging boxes and other procedures.
A Study Analysis of Fibers from Banana Trees in North Thailand for Product Creation
This research is the analytical study of fibers from banana trees in northern area. The study has been conducted on planted banana-species areas in 5 northern provinces. There are 9 studied banana species. The objectives of the studies are to utilize these mentioned banana species for product creation. It is also to find out the banana-fiber-extraction process for new materials used as guidelines to design new products which help generate extra revenue for farmers after harvest season. The result from the research indicates that the most appropriate species for the research is Musa acuminata Colla due to its strongest texture in term of thickness. The leftovers of banana (stalk and pseudo stem in dried form) after agricultural process have been extracted into straight fiber ropes. Then they are processed into straight fiber ropes through hand-cutting by northern villagers. As for the 5 types of natural fibers. It is found that banana fibers mixed with hemp fibers at 50% proportion for each yields the highest pull force of 678.71 N. To sum up the manufacturing production and creation is in a good level by average value 4.17 and the product users’ satisfactions is a good level by average value 4.07.
