Abstract
ABSTRACTHigh level of scientific data collection by direct recording and statistical analysis was deployed to actually determine the appropriate mixing ratios of the masses of base material virgin polymeric material and the colour additives master batches in the production of various plastic products. At each interval, production of the plastic products are detailed by measurable parameters of masses, the machines operational conditions were reasonably adjusted for maximum performance and these datas were finally evaluated. It is observed that a unit of 10L plastic gallon has values for the master batch additive at 80.68g, when added to 710g mass of the virgin HDPE when blown into a unit finished product. The High quality plastic Executive Hangers produced has a mixing texture (Mt) value of 88363.636 gm-1min-1 when 0.64g of colour additive is mixed with 80g of the virgin HDPE with base material yielding two pairs of the Executive Hangers from the 180 tons injection machine of plastic workshop of SEDI ENUGU NASENI. These elevated mass of the additive in the 10L gallon has been attributed to the nature of the production method of blow moulding, thorough mixing and blending. This was achieved before the pressure of 20bars are blown into the mould to form the desired shape of the product. Unlike the 180 tons Injection moulding machine which injects the melted mixture into the mould cavity through injection pressure from the turning hot screws from the barrel. However, at each interval of production process, adequate instrumentation was done to determine these relative important production parameters.KEYWORDS: Master batch ratios, Plastic products, Polymeric materials, Aesthetics, Performance enhancement.INTRODUCTION Polymeric materials create a versatile substrate for innovation by offering a wide range of properties responsive to various applications. Pucci et al. (2020), thorough selection and operation of polymeric constituents that play a crucial role in outlining the performance and aesthetic attributes of plastic products. Master batches, pigments, additives, and carrier resins, function as catalysts for innovative transformations by empowering manufacturers to excellently tune properties with precision (Gupta & Kandasubramanian, 2018). The mechanisms governing pigment dispersion within polymeric matrices, explaining how variations in master batch composition impact color consistency and vibrancy Rong et al. (2019). It was confirmed that there exist a robust relationship between master batch ratios, aesthetics, and performance enhancement in plastic product production. Furthermore the work of Lee et al. (2021) emphasizes on the importance of optimizing mechanical properties through master batch formulation by highlighting the role of additives in enhancing strength, flexibility, and impact resistance. Beyond aesthetics, the objective of performance optimization encompasses a diverse array of considerations spanning from environmental sustainability to functional durability. The research conducted by niu et al. (2019) underscores the pivotal role of UV stabilization in polymeric materials, elucidating how additives within master batches can ameliorate degradation and extend product lifespan in outdoor applications. Advancements in thermal management underscore the potential of master batch engineering to augment heat resistance and dimensional stability in high-temperature environments, as articulated by Zhang et al. (2022). It is this background that we confined this study to the use of selected base polymeric material which we use in the production of important plastic products such as the 10L gallon, sizeable high quality executive hanger, magnifying lens handle, 10L cap and plastic bowel and various virgin polymeric material such as HDPE, PP,PS,LDPE, LLDPE and GPPS. SEDI-ENUGU EXECUTIVE HANGERSThe executive plastic hanger is a high quality, durable hanger designed to support heavier and more delicate clothing items such as suits, jackets, coats, and formal wear. These hangers are often used in retail settings, upscale wardrobes, and by dry cleaners to provide a more refined presentation and better protection for garments. It has a wide shoulder to maintain the shape of jackets, coats and suits its hook even though if fixed to avoid a 360-degree rotation, it is also designed to have notches at the base frame for hanging skirts or garments with straps. It has a polished appearance that enhances the overall look of the closet. It has a unit mass of 0.2 kg (200 grams) made from different polymeric materials such as HDPE, PE, PS, GPPS. SEDI-ENUGU 10 LITRE JERRY CAN CAP The cap of 10-liter jerry can is a vital component that ensures the secure closure and containment of liquids stored within the can. The mass of SEDI-Enugu 10-liter jerry can cap weighed 0.095 kg, or 95 grams and is typically threaded to securely seal the opening of the can. It has features like the tamperproof or seal to prevent leakage, easy dispensing and evaporation of the stored liquid. This Jerry can caps are commonly produced from materials such as polyethylene (PE), polypropylene (PP), or high-density polyethylene (HDPE).SEDI-ENUGU 10LITER JERRYCAN This 10-liter jerry can is a robust container designed for the storage and transportation of liquids such as water, fuel, or chemicals having weight of 500grams. This was made from high-density polyethylene (HDPE) blow or similar durable plastic materials, these containers feature a sturdy construction to withstand rugged environments and harsh handling SEDI-ENUGU HANDLE OF MAGNIFYING LENS This is made from durable plastic materials such as pp. injection. These handles are designed to enhance user experience during tasks such as reading, crafting, or examining small objects through the magnifying lens. In the manufacturing process, injection moulding stands as the predominant process for producing plastic handles where it solidifies to form the desired handle shape. This process involves cost-effectiveness, scalability, and ability to achieve intricate geometries. SEDI-ENUGU PLASTIC BOWEL This was blowned into this shape by the 6ft blowing machine with a one cavity mould into the desired shape. The additive colour was red which was blended homogeneously with the virgin material. It has diameter of 12inches, with thickness 3mm, with volume capacity of 1litre and highly elastic. It was made with HDPE but can also be blown with other polymeric materials such as PE, PS and GPPS, it is mostly used for a variety of purposes in the kitchen.
