NGHIÊN CỨU ẢNH HƯỞNG CỦA NHIỆT ĐỘ SẤY CHUYỂN HÓA LÊN CẤU TRÚC VI MÔ VÀ TÍNH CHẤT CƠ HỌC CỦA THÂN TRE
Nội dung chính của bài viết
Tóm tắt
Tre là vật liệu sinh thái tiềm năng nhưng độ ẩm cao và hiện tượng nứt trong sấy gây khó khăn cho ứng dụng công nghiệp. Nghiên cứu dùng nhiễu xạ tia X (XRD) và các phép đo cơ học theo TCVN 8048:2009 để đánh giá ảnh hưởng của nhiệt độ sấy chuyển hóa (110, 130, 150 °C) đến cấu trúc vi mô và tính chất cơ học của thân tre luồng.
Độ bền uốn tĩnh và nén dọc thớ của các mẫu sấy chuyển hóa tăng đáng kể so với đối chứng nhưng giảm dần khi nhiệt độ tăng, phù hợp xu hướng suy giảm độ kết tinh cellulose. Độ bền kéo dọc thớ giảm nhẹ nhưng vẫn trong khoảng đặc trưng của tre bền cao; 110 °C cho hiệu quả tốt nhất.
Kết quả là cơ sở để tối ưu điều kiện sấy chuyển hóa trong sản xuất công nghiệp, rút ngắn thời gian sấy mà vẫn đảm bảo chất lượng. Cần nghiên cứu thêm ở nhiệt độ dưới 110 °C để xác định điều kiện tối ưu.
Từ khóa
thân tre, nhiễu xạ tia X, sấy chuyển hóa, độ kết tinh cellulose, tính chất cơ học
