摘要
研究测定了异氰酸酯、脲醛树脂和酚醛树脂胶粘剂对高梁秆与玉米秆表面的接触角,并通过测量不同表面张力的液体对秸秆表面的接触角,推算出秸杆表面的自由能。结果表明:秸秆的表面自由能比木材要低得多,属于低能表面固体。
In this study, the contact angle among methane diisocyanate(MDI), urea formaldehyde resin(UF) and phenol formaldehyde resin (PF) on surface of sorghum stalk and corn stalk were tested, and the surface free energy of two stalks was reckoned by testing the contact angle of liquid with different surface tensile on each stalk. The result showed that the surface free energy of two stalks was lower than wood: they were solids of low energy surface.
