Abstract

The invention relates to production equipment for a soluble material film, a pipeline heater and a film making method thereof. The production equipment comprises a liquid storage mechanism, a solution treatment mechanism, a raw material dissolving mechanism, a negative-pressure defoaming mechanism, a vacuum drying mechanism and a finished film treatment mechanism which are sequentially connected through a pipeline, wherein the vacuum drying mechanism communicates with the liquid storage mechanism through a steam recycling pipeline connected above; after raw materials are mixed with a solution, the mixture is injected into a film-forming feeding mold head from a high-pressure supply pump and is extruded into films for being dried in the vacuum drying mechanism; and the dried films are mechanically treated in the finished film treatment mechanism to obtain finished product films, and are rolled and stored by a rolling roller. The pipeline heater adopted by the production equipment can prevent gel on the tube wall in a solution heating process. The production equipment is combined with the film making method thereof, so that films can be continuously produced according to needs, and the mechanical properties and color of the films are not affected.

Description

technical field [0001] The invention relates to the field of film production equipment, in particular to a production equipment for soluble material films, a pipeline heater for increasing the temperature of raw materials or solutions in the production equipment, and a production equipment for producing soluble material films. membrane method. Background technique [0002] Polyvinyl alcohol (PVA) film is recognized as an excellent fully degradable environmentally friendly packaging and multi-purpose film used in other fields; it has better light transmittance, tear resistance, low static electricity, and air tightness than the commonly used plastic films. Sex, water solubility and 100% degradable and so on. The application covers the fields of industry, agriculture, civilian, business, and military, and it is the first choice for plastic products to solve the world problem of white pollution in the future. [0003] At present, the market is used to produce PVA film based o...
