Formulation of waste plastic PVC granulation Due to the greater degree of degradation of PVC products during use, their degradation is more severe when they are processed at high temperature again. Therefore, general recycled PVC must be added with some heat stabilizers during granulation, which can greatly improve the regeneration of pellets. Various indicators. (1) Formula of
Problems and causes in the production of PVC cable particles: 1. From the particles (shape rules) Mixing: uneven mixing, plasticizer wraps PVC, and particles occur; Dead end: Refers to the fact that the barrel is not cleaned up when different batches are mixed, and the residual material is excessively gelatinized Extrusion: temperature is not good, poor gelatinization, a
The main working mode of the PVC granulator is granule wet granulation. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted after adjusting the humidity in the cylinder. Under certain liquid phase conditions, with the help of the rotation of the cylinder, The squeezing force between the material particles is aggregated into a ball. Chinese name PVC granula
Although the pvc granulator is a relatively easy-to-operate machine, it still needs to pay attention to some problems in the specific use process. First, we must pay attention to the chain reaction between the main motor and the feeder. The feeder cannot be started when the main motor is not started. The second is that the raw materials cannot be mixed with any metal, otherwise it will damage the
PVC granulator characteristics and matters needing attention Pvc granulator is rare in daily life, because it is a professional machine and it is granulated by agglomerate wet method. Through a certain amount of water or steam, the basic fertilizer can fully complete the chemical reaction in the cylinder, and under certain liquid phase conditions, it can be agglomerated into balls.
Related problems, formulations and solutions in PVC granulation problem: Granulated with PVC recycled materials, the raw material is the broken material of luggage leather. The problem now is that the density of the granules I made is not good. There are slight pores in the middle of the granules, which are not dense, the surface is still thorny, and there is no finish. The formula is 50
The granulation process is the production process of high polymer resin and various additives and auxiliary agents into granulated plastic through metering, laminating, plasticizing, and pelletizing. Plastic granules are semi-finished products of plastic molding and processing industry, and are also extruded. , Injection molding, hollow blow molding, foaming and other raw materials for processing.
PVC is polyvinyl chloride. The quality of the non-slip bathroom mats made of this material is good. The price is not too expensive. No matter how you fold it, it will not be deformed, and it will not produce any taste. No matter how long you use it, it will not fade. Bring you Super quality, low price, even if the temperature is high, it will not damage the anti-skid floor mat of PVC material, a
