การใช้เศษพลาสติกโพลิเอทธิลีนเทเรฟทาเลตเป็นวัสดุผสมสำหรับผลิตไม้เทียมขยะกล่องนมที่มีความแข็งแรงสูง
The objectives of this research are to study the production to find the proper ratio to test the properties to suggest the implementation and to transfer the technology of high strength milk carton waste artificial wood mixed with poly ethylene terephthalate (PET) plastic waste. The ratios of this artificial wood included milk carton waste: PET plastic waste equal to 80:20 75:25 70:30 65:35 and 60:40 by weight. The milk carton and PET plastic wastes were grinded though sieve no.4. The artificial woods were casted by hot compression with 180 degree of Celsius for 5 minutes. The samples tested follow the TIS.966-2547 standard. From the results the 60:40 of ratio was the proper ratio which can pass the standard. The increasing of PET waste effected to decrease the density moisture and swelling of properties. In case of bending strength elastic modulus and tensile strength perpendicular to surface the increasing of PET effected to decrease their properties. The developed artificial wood mixed with milk cotton waste and PET plastic waste has the possibility to implement in decoration and construction both interior and exterior wall building. These results can register the petty patent and write the research paper which to transfer the technology.
การใช้เศษกระดาษเหลือทิ้งเป็นมวลรวมในบล็อกประสานมวลเบาจากหน้าดินขาว
The objective of this research is to study about physical mechanical and thermal insulation properties of light-weight Kaolin top soil interlocking block mixed with milk carton waste. The ratio of cement: aggregates (Kaolin top soil and milk carton waste): sanitary water is 1: 7: 1 by weight. 10 ratios of aggregates (Kaolin top soil to milk carton waste ratio) are fixed at 7: 0 6.8: 0.2 6.6: 0.4 6.4: 0.6 6.2: 0.8 6: 1 5.8: 1.2 5.6: 1.4 5.4: 1.6 and 5.2: 1.8 by weight. The interlocking block samples are cast for testing the necessary properties followed the TCPS standard 602-2547. From the experiment the best Kaolin top soil to milk carton waste ratio which has the most milk carton waste and can pass the standard is 6.2: 0.8. The suitable quantity of milk carton waste can reduce the density water absorption and thermal conductivity of Kaolin top soil interlocking block.
