Abstract

Polyethylene Wax merupakan produk sampingan dari pembuatan polietilen yang saat ini belum banyak dimanfaatkan. Dampak pengenalan polyethylene wax, pada karakterisasi fisik, sifat mekanik dan termal high-density polyethylene (HDPE) dengan konsentrasi 2,5 hingga 15% berat diselidiki pada polyethylene film. Sebaliknya, hasil glass transition temperature yang bergantung pada komposisi tunggal dari percobaan diterima sebagai bukti untuk campuran polyethylene wax amorf yang dapat larut. Dispersi polyethylene wax dalam matriks sangat bergantung pada persentase polyethylene wax yang dimasukkan ke dalam matriks dan morfologi polietilen amorf itu sendiri. Efek anti-plastisisasi pada matriks meningkatkan kekuatan mekanik HDPE. Menurut data, anti-plastisisasi terjadi dengan memperlambat gerakan molekul polyethylene wax dalam matriks di bawah konsentrasi kritis. Memahami parameter yang memengaruhi stabilitas termal, integritas mekanis, dan kinerja campuran polietilen secara keseluruhan akan memungkinkan polimer digunakan secara luas. Dalam percobaan ini, meningkatkan konsentrasi polyethylene wax dalam matriks dengan kuat memperlambat pertumbuhan ikatan dan meningkatkan efek negatif pada kekuatan tarikan HDPE, sebuah fenomena yang dikenal luas sebagai efek plastisisasi. Peningkatan melt flow index dan melting temperature yang lebih rendah memberikan kesepakatan yang baik terkait dengan kemampuan pemrosesan polietilen. Semakin mudah polimer untuk diekstrusi, semakin sedikit energi yang dibutuhkan untuk peralatan karena dengan penurunan kekentalan, semakin mudah screw berputar, dan semakin sedikit energi yang diterapkan pada polimer. Penyelidikan konsentrasi ambang batas 2,5 hingga 7,5% ditemukan bahwa peningkatan efisiensi produksi HDPE dengan mensubstitusi polyethylene wax yang merupakan produk samping yang dihasilkan sebagai agen plastisisasi dalam produk utama dan menurunkan daya operasi ekstrusi dapat dicapai.

Polyethylene wax is a side product of the polyethylene manufacturing which is not widely utilized at this current time. The impact of introducing polyethylene wax, on the physical characterization, mechanical and thermal properties of high-density polyethylene (HDPE) with a concentration of from 2.5 to 15%wt investigated on polyethylene film. In contrast, a single composition-dependent glass transition temperature result from the experiment is accepted as evidence for an amorphous miscible blend of polyethylene wax. Polyethylene wax dispersion in the matrix strongly depends on the percentage of polyethylene wax introduced to the matrix and the amorphous morphology of polyethylene itself. The anti-plasticization effect on the matrix raises the mechanical strength of the HDPE. According to the data, anti-plasticization occurs by slowing the motion of polyethylene wax molecules in the matrix below the critical concentration. Understanding the parameters that influence the thermal stability, mechanical integrity, and overall performance of polyethylene blends would allow the polymer to be broadly used. In this experiment, increasing the polyethylene wax concentration in the matrix vigorously slows bonding growth and promotes a negative effect on the tensile strength of HDPE, a phenomenon widely known as the plasticization effect. An increase in melt flow index and a lower melting temperature gives good agreement related to polyethylene processability. The easier the polymer to extrude, decrease the energy required for the equipment because as the viscosity decreases, the easier the screw to rotate, and less energy is applied to the polymer. The investigation of the threshold limit concentration 2.5 to 7.5% found that increasing the production efficiency of HDPE by substituting the side product polyethylene wax generated as plasticizer agent in the main product and lowering the extrusion operating power.
