Article Introduction
In the daily production process of PVC pipes, If there are bubbles in the pvc pipe, the temperature at the die should be slightly lower, and the extrusion speed should not be too fast to eliminate the bubbles in the pipe. At the same time, when cooling and shaping, it is not advisable to use rapid cooling, otherwise, the pipe will easily produce bubbles, These directly lead to the failure of pipeline production.
So Please carefully read the following article to understand how to solve the bubble problem in PVC pipe production !
Here we introduce for you:
1. Material situation
May be because the material’s water is too high, this time on the need for drying the PVC pipe or changing the nozzle;
2. Stirring temperature
May be because PVC pipe mixing temperature is low, there is no discharge of water, this time on the need to increase the compounding temperature;
3. Blockage
Maybe due to the low degree of vacuum or vent pipes get clogged, this time need to check the pump and piping;
4. Mold temperature
Maybe due to the body or the die temperature is too high, you need to reduce the temperature;
5. Stable performance
Maybe because PVC pipe mixed ingredients thermal stability is poor, this time you need to check the recipe modification.
Summary
In general, when producing PVC pipes, it is necessary to always pay attention to the status of the pipes when they are produced. If abnormal conditions such as bubbles are found, timely adjustments need to be made. Mainly check the material condition, stirring temperature, blockage, mold temperature, performance stability, etc. This will avoid the production of a large number of unqualified pipes due to production reasons and avoid wasting production costs.
