บทคัดย่อ
งานวิจัยนี้มีวัตถุประสงค์เพื่อศึกษาปริมาณฝุ่น PM2.5 ของธูปจากขี้เลื่อยไม้สักและผงใบมะกรูดในอัตราส่วนที่แตกต่างกัน โดยได้ทำการหาค่าความชื้นและความหนาแน่นของขี้เลื่อยไม้สักและผงใบมะกรูด รวมถึงทำการผลิตธูปในอัตราส่วนขี้เลื่อยไม้สักต่อผงใบมะกรูด จำนวน 6 สูตร ได้แก่ สูตร A (100: 0) สูตร B (80: 20) สูตร C (60: 40) สูตร D (40: 60) สูตร E (20: 80) และสูตร F (0: 100) จำนวนสูตรละ 10 ซ้ำ รวมทั้งสิ้น 60 แท่ง ผลการทดลองพบว่าค่าความชื้นต่ำที่สุดคือขี้เลื่อยไม้สักซึ่งมีค่าความชื้นเฉลี่ยร้อยละ 10.93±0.72 ส่วนค่าความหนาแน่นที่สูงที่สุดคือผงใบมะกรูดซึ่งมีค่าความหนาแน่นเฉลี่ย 239.06±6.87 กิโลกรัม/ลูกบาศก์เมตร และธูปสูตร A มีปริมาณฝุ่น PM2.5 น้อยที่สุดเฉลี่ย 266.96±9.21 µg/m3 โดยปริมาณของผงใบมะกรูดที่เพิ่มขึ้นในธูปจะส่งผลต่อปริมาณความหนาแน่นของธูปทำให้ปริมาณฝุ่น PM2.5 เพิ่มขึ้น
คำสำคัญ: ขี้เลื่อยไม้สัก ความหนาแน่น ธูป ผงใบมะกรูด
Abstract
This research aimed to study the PM2.5 dust content of incense sticks from teak sawdust and kaffir lime leaves powder in different ratios. The moisture content and density of teak sawdust and kaffir lime leaves powder were determined, and incense was produced in 6 different ratios of teak sawdust to kaffir lime leaves powder: Formula A (100:0), Formula B (80:20), Formula C (60:40), Formula D (40:60), Formula E (20:80), and Formula F (0:100), with 10 repetitions per formula, totaling 60 sticks. The experimental results showed that the lowest moisture content was found in teak sawdust, with an average moisture content of 10.93±0.72%. The highest density was found in kaffir lime leaves powder, with an average density of 239.06±6.87 kg/m³. Incense made with Formula A had the lowest PM2.5 dust concentration, averaging 266.96±9.21 µg/m³. The increase of kaffir lime leaves powder in the incense affected the PM2.5 dust concentration.
