摘要
本研究调查了海草Zostera marina (ZM)叶片作为生产中密度板的替代原料的潜力。第一部分对不同海草的拉伸强度进行了研究。海棠纤维(POF)的平均抗拉强度可达123 MPa,其叶片(POL)的平均抗拉强度可达27 MPa。ZM叶片的抗拉强度与大洋水仙叶片相近,均为22.9 MPa。在第二部分,ZM叶片和木纤维(WF)进一步加工,以生产密度在500至700 kg m−3之间的中密度板。对这些板进行了防火性、导热性、机械强度和防水相关性能的评估。与密度相似的木纤维板(WF),即中密度纤维板(MDF)相比,zm板具有较高的耐火性和较低的导热性。然而,由于海草叶片的低抗拉强度和独特的形态,与木纤维(WF)制成的板材相比,zm板显示出较低的抗折强度(高达10.9 MPa)和较低的吸水阻力。Zostera marina公司生产的板材可以作为商业中密度纤维板的一个很有前途的替代品,特别是在室内应用中,优先考虑防火和隔热,但它们主要适用于非结构用途。对其声学特性的进一步研究将评估其作为吸声建筑面板的潜在应用。
Single fiber tensile strength of seagrasses and the development and characterization of Zostera marina-based medium density boards
This study investigates the potential of the leaves of the seagrass Zostera marina (ZM) as an alternative raw material for the production medium-density boards. In the first part, the tensile strength properties of various types of seagrasses were investigated. Posidonia oceanica fibers (POF) exhibited a mean tensile strength of up to 123 MPa, while its leaves (POL) reached up to 27 MPa. The ZM leaves also showed a similar tensile strength to Posidonia oceanica leaves, 22.9 MPa. In the second part, ZM leaves and wood fibers (WF) are further processed to produce medium density boards with densities ranging from 500 to 700 kg m−3. The boards were evaluated for fire resistance, thermal conductivity, mechanical strength, and water resistance-related properties. ZM-boards demonstrated high fire resistance and lower thermal conductivity compared to boards based on wood fiber (WF), i.e. medium density fiberboards (MDF), of similar density. However, due to the low tensile strength and unique morphology of the seagrass leaves, ZM-boards display a lower flexural strength (up to 10.9 MPa) and lower resistance to water absorption compared to boards produced from wood fibers (WF). Boards made by Zostera marina can be a promising alternative to commercial MDF panels especially for interior applications prioritizing fire protection and thermal insulation but they are mainly suited for non-structural uses. Further examination of its acoustic properties would assess its potential applications as sound-absorbing architectural panels.
