ABA film blower is to heat and melt plastic particles and then blow them into thin films. There are many kinds of film blowing machines, such as PE, POF, PVC and so on. The new material is blown out with brand-new particles. The color is uniform, clean and the bag is well stretched. The main reason for the poor production of recycled materials is that their properties may vary from batch to batch. In production, the ratio of recycled materials is determined by checking the raw materials, understanding the hardness, density, melting index, blending with other recycled materials and blending with the same good materials.
In order to ensure the physical properties and transparency of the film by using recycled materials to a certain extent, it can be understood that the longitudinal tensile force is very poor. It is recommended that you test under high pressure: linearity = 2:3, and then do not add too much recycled materials. A package of metallocene can also be properly added to the inner layer. How much material is needed in an hour, which is usually below 120 HP and 20 HP. If it is centralized cooling, it depends on the specific situation.
At present, our company has purchased Jinming Machinery, KC-050FA chiller, Kaidley brand, for three centralized cooling use. Particles are usually grey, and pigments are usually added to make bags. The bags are unevenly colored, brittle and fragile, and the price is low.
Although it is a recycled plastic bag, it is generally a waste bag in the process of bag making and in the general sense. If you want to be more efficient, you need to strengthen the cooling system of the film blower. If you don't have enough cooling, you should use internal cooling or water cooler or other cooling equipment. Plasticized quality A screw must first be able to produce products that meet the quality requirements.
The so-called quality requirements refer to that the products produced should meet the requirements of the following aspects: 1. Have all kinds of properties that meet the requirements. Whether there is pressure fluctuation in the melt. Whether the dispersions of dyeing and other additives are uniform or not. Unit consumption unit consumption refers to the energy consumption per kilogram of plastic (rubber) extruded, generally expressed in N. Among them, N is power (kilowatt) and Q is output (kilowatt/hour). It is difficult to make a good screw. It must also be easy to process and manufacture, with low cost.
