Problems solved by technology
[0002] Because PVC film has excellent characteristics such as rainproof, fire resistance, antistatic, easy to form, etc., there are certain requirements for the production process of some PVC film particles in the market; however, the existing production process of PVC film particles is relatively complicated, PVC The particle size of the film particle powder is not uniform enough, the plasticization is not uniform enough, the PVC film produced and processed is generally flexible and has a short service life; therefore, it is very necessary to invent a production process for PVC film particles at this stage

The invention discloses a PVC film particle production process. The process comprises the following steps of 1, material selection and blending; 2, heating and mixing; 3, material cooling; 4, stirring and kneading; 5, mixing and clustering; 6, refining processing; and 7, filtering purification. In the step 2, the stirring speed of a stirrer is 500-700 r / min; in the step 3, when raw materials are cooled to 40-50 DEG C, cooling is stopped; in the step 4, the stirring time is 10-15 minutes, and the kneading temperature is 80-120 DEG C; and in the step 7, according to the filtering mode, the materials are sequentially filtered through a 20-mesh filter screen, a 50-70-mesh filter screen and a 120-150-mesh filter screen. The PVC film particle production process is safe and reliable, the steps of the PVC film particle production process are simple, produced PVC film particles are uniform in particle size through multi-layer multi-time filtering treatment, and PVC films produced and processed through the PVC film particles are uniform in plasticization, high in flexibility, not likely to be torn, long in service life and convenient to use and popularize.
Description
technical field [0001] The invention relates to the technical field of PVC film particles, in particular to a production process of PVC film particles. Background technique [0002] Because PVC film has excellent characteristics such as rainproof, fire-resistant, antistatic, and easy to form, there are certain requirements for the production process of some PVC film particles in the market; however, the existing production process of PVC film particles is relatively complicated. The particle size of the film particle powder is not uniform enough, the plasticization is not uniform enough, the PVC film produced by production and processing is generally flexible, and the service life is short; therefore, it is very necessary to invent a production process of PVC film particles at this stage. Contents of the invention [0003] The purpose of the present invention is to provide a production process for PVC film particles to solve the problems raised in the above-mentioned backg...
