Brief Analysis On The Structure Of Plastic Bag Making Machine
- Jun 20, 2017 -

    The plastic we usually use is not a pure substance, it is made of many materials. Among them, high molecular polymer (or synthetic resin) is the main component of plastic, in addition, in order to improve the plastic

Of the performance, but also in the polymer to add a variety of auxiliary materials, such as fillers, plasticizers, lubricants, stabilizers, coloring agents, etc., can become a good performance of plastic.  1, synthetic resin Synthetic resin is the most important component of plastic, its content in the plastic is generally 40% to 100%. Because of the large content, and the nature of the resin often determines the nature of the plastic, so people Often resin as a synonym for plastic. For example, the PVC resin and PVC plastic, phenolic resin and phenolic plastic confused. In fact, resin and plastic are two different concepts. Resin is a kind Plastic Bag Making Machine Raw raw polymer, it is not only used in the manufacture of plastic, but also paint, adhesives and synthetic fiber raw materials. While the plastic in addition to a small part of the 100% resin, the vast majority of plastic, In addition to the main components of the resin, but also need to add other substances. 2, filler filler, also known as filler, it can improve the strength of plastic and heat resistance, and reduce costs. Such as phenolic resin can be added after adding wood powderGreatly reduce the cost of phenolic plastic to become one of the cheapest plastic, but also significantly improve the mechanical strength. Fill can be divided into two kinds of organic fillers and inorganic fillers, the former such as wood flour, rags, paper and the Such as glass fiber, diatomaceous earth, asbestos, carbon black and the like. 3, plasticizer plasticizer can increase the plasticity of plastic and soft, reduce the brittleness, so that easy to plastic molding. Plasticizer Plastic Bag Making Machine It is a kind of organic compound which is miscible with resin, non-toxic, odorless, light and heat stable, and most commonly used is phthalate. Such as the production of PVC plastic, if the addition of more plasticizers will be

Can be soft PVC plastic, if without or less plasticizer (dosage <10%), then the rigid polyvinyl chloride plastic. 4, stabilizer in order to prevent the synthetic resin in the processing and use of the process of light and heat role Decomposition and destruction, to extend the service life, to be added in the plastic stabilizer. Commonly used stearate, epoxy resin and so on. 5, coloring agent can make plastic with a variety of bright, beautiful colors. Commonly used Machine dye and inorganic pigments as a colorant 6, the role of lubricant lubricant is to prevent the plastic molding in the non-sticky metal mold, while the plastic surface can be smooth and beautiful. Commonly used lubricants are stearic acid and Its calcium and magnesium salts. In addition to the above additives, the plastic can also add flame retardants, foaming agents, antistatic agents, etc., to meet the different requirements.Plastic Bag Making Machine
