Plastic particles mixed with the ingredients of the quality of the packaging container


ixingprocessofplasticrawmaterialandmixture. The production of plastic packaging containers, general molding process requires adding lubricants or other ingredients, particularly the requirement to use Ru solid colorants or inorganic fillers added. Operation of various additives mixed quality of the performance of a given product is very important process, and the plastic particles and evenly mixed with the agent level, to the performance of the finished product processing technology also brings a certain extent. Mixing processes in the improper handling of ingredients and mixed uneven, are likely to cause the appearance of containers or containers to prevent quality defects inherent quality defects, improve product quality, mixed material must first master the relevant quality standards and requirements, mainly includes two aspects: First, a good mix of materials to packaging container products to ensure good mechanical properties and performance: the second is materials processing technology itself has a good performance. To achieve these requirements must be co-operation process in Queensland. After the various ingredients and evenly dispersed in the base plastic granule surface. Combination of a certain physical state, and to ensure consistent performance. Second operation time as short as possible, which will help improve production efficiency and reduce energy consumption. To achieve this, the raw material mix to do the following procedures should be noted that several aspects: First, to pre-processing of raw materials into the factory for the raw materials, auxiliary materials quality. Producer Shandong Xinhua Pharmaceutical Factory-made units manufacturers can be guaranteed. However, as in the transport, storage, keeping the process susceptible to tidal and other effects. Therefore, before use of raw materials, technical standards should be strict quality inspection,[link widoczny dla zalogowanych], do not meet the requirements. But also to supplement added]:. The usual processing means for: a. Drying process: raw materials containing excessive, powder easy to agglomerate. If not pre-processed. Molding process in the product is easy to produce bubbles and other defects, so before using the original materials into the greenhouse or to add a special heating and drying in the dryer. Pay attention to where the water until it reaches the quality standards, b. Screening NT-: The purpose of screening is to remove all mechanical impurities in raw materials, materials such as sand, wood chips and lumps caused by the junction with the agents of large particles c. Kom broken processing: the block or coarse granular raw materials for citrus broken, ground, easy to spread evenly in the mixture =, the title and the ratio of raw materials raw materials should be accurate weighing operation is in accordance with the provisions of the various formulations with the agent of the species, size ratio of the number of the weighing process. Plastic raw materials and a reasonable proportion of various materials. To ensure product quality and avoid all kinds of defects play an important role. Because no matter how good the design of the formula, they have through the weighing process and the accuracy of this ratio to increase to achieve, and therefore the amount and ratio of indemnity process. Weighing instruments used on,[link widoczny dla zalogowanych], such as balance, and Taiwan said that should be required to carefully check. When you do detailed, accurate, missed with the use or misuse of agents. Ding I; cattle s'h) Third, a reasonable choice of raw materials mixing degree of mixing equipment is the main factor in the temperature of mixer,[link widoczny dla zalogowanych], mixing time, ravioli combined number of materials and mechanical stirring speed increases the temperature under normal circumstances, mixing pulp and raw materials to increase contact area to reduce material thickness of solid material particles are conducive to the spread of hybrid relies mainly on the role of diffusion, convection and shear three roles to achieve. Convection of material is often achieved by mechanical agitation forces. Shear increases the surface area materials can expand the distribution area of ​​materials, mixing materials to achieve the purpose. Often choose plastic mixing equipment: a. z slurry mixing and high-speed mixer: z slurry mixer's main components are: a saddle-shaped with the end of the mixing chamber and a pair of S-or z-shaped stirring paddle. Mixed material by the rotating impeller units along the mixing chamber wall on the turn. In the middle of the whereabouts of the mixing chamber. Spiral impeller, so that axial movement of materials along the blade. This material will be pinched by the effect of repeated folding and tear. So as to achieve uniform mixing: high-speed mixer is cylindrical mixing chamber by a park located in the mixing chamber and a mixing device composition. The mixing efficiency. Each mixing cycle only two to three minutes mixing is carried out under confined conditions. Mixed dust flying less. Health conditions are good. Automatic unloading equipment, low labor intensity. b. Drum mixer: the drive components and a rotation of the container can be sealed components,[link widoczny dla zalogowanych], raw materials are mixed in a closed rotation. Orange dust flying less, and automatic discharge drawback is poor mixing, mixed cycle length. c. Paddle Mixer: It has a strong mixing force, shorter mixing cycles, higher production efficiency. The disadvantage is mixed dust flying serious and need to manually discharge,[link widoczny dla zalogowanych], greater labor intensity of the China Packaging j996 16 No. of 6g
