Plastic film technology of dry compound

Three sets of flexible packaging manufacturers should be prepared to roll in order to ensure cable production. b) the amount of the scraper and the glue relationship: the more tightly on the blade to force the less plastic, the closer the network cable roller tangent, the less glue on the contrary, the more and more. This can not be ignored. C) drying tunnel temperature control by solvent evaporation to consider, as long as the solvent evaporates out of the line, otherwise the solvent inside the bag to do the taste and affect product quality. On the other hand should also consider driving speed, the faster the drying time shorter stay hang on, the higher the required temperature, so as to bake out the solvents. d) when used Q cable roller and maintenance: the end of each laminating roller to clean up the cable, in particular, to use thinner copper brush and glue the grid are cleared to ensure the normal use next time. With the increase in the number of days by car, always check the network cable to the wear of rolls and the grid with the case of curing adhesive, only observed with a magnifying glass is far enough, we have the quality of the accident several times because of the glue less caused. Thus, after two months of continuous use new network line roller want to change. e) horizontal and vertical wrinkle wrinkle reasons: the causes of cross-wrinkled membrane by two layers does not match the result of tension, the plastic film itself under a certain tension in the stretch, when a film (thickness, the tension is a) is stretched, the tension-N loss, reinstate it, a process that arises after the cross-fold, stretching the more severe the greater the cross-fold. Crease the key to see whether the vertical roll levels. There is not a level of material into the steel roller will not be after the formation of a pressure, so special to seriously check into the lamination roller steel roller level of the previous degree, not to deform. f) the bubble causes and solutions: bubbles for several reasons: First, as with plastic uneven solvent evaporation when the mixing is not completely generated,[link widoczny dla zalogowanych], the second is on the rubber roller and the hot point and line roller with Ma pattern caused by a hot roller is not pressed three, four is too little concentration on the partial thin glue. These problems should be aware that the warm winter, the plastic should be warm, the ambient temperature can not be too low. g) Moisture: thin compound containing some water, resulting in decreased adhesion. Therefore, the quality of thinner to note. Humidity also seriously affected the adhesive. Generally greater than 70% humidity will not be able to ensure the normal glue. Nepal is in its summer workshop high temperature volatilization of acetone, resulting in very low temperature adhesive systems, water vapor in the roller and roll part of a large number of cable condensation,[link widoczny dla zalogowanych], destruction of the coated plastic state,[link widoczny dla zalogowanych], and would seriously reduce the adhesive bond strength . h) environment: dust in the air will adhere to the film,[link widoczny dla zalogowanych], the impact of adhesion, particularly at the oven outlet, strong airflow will be sandwiched dust particles, lavished on the film. It should ensure that the environment clean and keep the air filter at regular cleaning ISl. We discussed above the impact of dry compound factors and improve the effect of re-glue some ways, the normal production process is quite complicated in the analysis of a quality problem, you also need a more comprehensive and integrated consideration.
