What's the problem with excessive lubricants and demodels?

Release time:2026-09-26

quick answer

Internal and external lubricants can reduce friction and improve demolitions, but use can affect plasticization, welding and reprocessing. Material mechanisms, plasticization parameters, risk diagnosis and validation methods illustrate the problems associated with overloading of lubricant and demodulant, helping to stabilize the quality of retrofitting plants and reduce waste and equipment losses.

The “problems associated with excessive lubricants and demodels” should be evaluated by matching three sets of evidence on the state of particles, the behaviour of the melt and the quality of the finished product. The key mechanism for this theme is that internal and external lubricants can reduce friction and improve demersalization, but the use can affect plasticization, welding and reprocessing. Filling, flame retardants, chromosomals and assistants alter friction, heat transfer, viscosity, corrosion and final performance, requiring a combination of formulation and equipment. Therefore, the name of the material and the recommended setting can only be used as a starting point, and the actual judgement is to return to the plate number, water, filling and assistor, the single total quantity, cycle, screw structure and product requirements to confirm whether the temperature, cut and stay of the material in the equipment is safe.

At the test-model or volume-import phase, an input list should be established around “problems associated with excessive lubricants and demodels”, including feedstock suppliers and batches, technical data tables, dry conditions, colour mother and retrofit ratios, equipment and screw specifications, product and flow weight, mold temperature and existing defects. For products with multiple cavities or thin differences, the weight of the cavities should also be compared with the critical dimensions to prevent averages from covering up local problems. The main risks to the subject are that excessive quantities may cause slippage, distillation, spraying and a decrease in the intensity of the melting line. Parameters must be recorded in a specific pattern to distinguish material from equipment from operational changes.

Control methods should not begin with blindly increasing temperature or pressure, but should be based on "substance state - feed drying" The sequence of screw plasticization - nozzles and fluids - product results. Where the defects can be temporarily pressured by extreme temperatures or back pressure, it is more important to confirm the existence of structural, water-bearing, pollution or gaping problems. The site adjusts only one main variable at a time, while observing the actual melting temperature, measuring time, screw twists, mats, injection pressure, product weight, colour, scent and critical dimensions. If production can only be sustained by extreme parameters, the use of a switch to cover the material or hardware boundary should be discontinued.

The verification of “problems associated with excessive lubricants and demodels” suggested a repetitious approach: examination of formulations, decomposers, screws slide, surface and weld strength. It is recommended that a valid window be entered into the material database and that the approving officer, date, equipment, screw and raw material version be recorded. The technical agreement between the supplier and the plant shall state the material, the sampling method, the detection project, the permitted scope and the change notification requirements. The plasticization programme can only be considered to have long-term quantitative value if the product ' s probabilities, performance, cyclicality, energy consumption and maintenance costs are met in a continuous production process.
