With the development trend of e-commerce industry, logistics enterprises and manufacturing industry, many processing plants or freight logistics in the delivery of goods are using many packaging products, such as PP packing belt, plastic steel packing belt, inflatable bags, binding belt, bubble mat, paper boxes these goods.
Before because there are relatively large items of goods, and more heavy, so most of the choice is steel chain packing, but a drawback of the steel chain is too sharp, very easy to cause damage to the application of staff, often see the application of staff accidentally cut the door handle.
Fortunately, with the development trend of China's economic development and the development of science and technology, plastic steel packaging belt should be born, it is made of plastic, but the tensile and compressive strength is not lost with the steel chain, so many companies have just started to choose plastic steel packaging belt to carry out packaging goods.
Today, Mengmao packaging and everyone talk about the production process of plastic steel packing belt must be added to some plastic additives, the key is the following categories:
1, light stabilizer: light stabilizer can be based on shielding and digestion absorption of ultraviolet light, quenching excited kinetic energy capture oxygen free radicals and other methods to manipulate the photooxygen catalytic dissolution of high polymer reflection, and then give the product excellent light smooth practical effect, increase their use period.
2, processing aid: processing aid key in order to improve the production and processing characteristics of plastic forming and the development and design of an improved modifier. Production and processing temperature of plastic profile is close to the dissolution temperature, poor fluidity, easy to stick to the machine equipment coking plant, so in the production and manufacturing of plastic profile must add a certain amount of processing AIDS to get rid of the shortcomings of plastic profile itself.
3. Lubricating fluid: the key function of the lubricating fluid is to reduce the mutual friction between the polymer and the production equipment and the molecular structure of the polymer, avoid the dissolution of epoxy resin caused by excessive friction heat, and improve the high efficiency of the thermal stabilizer.
4, heat stabilizer: plastic profile is heat sensitive plastic, so in the production of plastic profile, heat stabilizer is indispensable. The metal salt in the heat stabilizer can digest and absorb HCl dissolved by PVC, so it can slow down the dissolution rate of plastic and increase the dissolution time. The common compound lead acid salt in the production and manufacturing of plastic profiles has the advantages of thermal stability, high efficiency, high quality and low price.
5, impact resistant modified materials: if not impact resistant modified materials in the production and manufacturing of plastic profiles, plastic profiles will be very brittle and hard, a little impact, more fragile. In the manufacture of plastic profiles, the key materials of impact resistant agent modification are as follows: chlorinated polyethylene, polyacrylate, butadiene-butyl acrylate polymer.
