Is it necessary to clean the extruder every day during the production of PVC transparent conduit (PVC material)?

But there are some exceptions, such as:

1, replace raw materials from different manufacturers for production.

2. When replacing different plasticizer raw materials for production, especially when replacing raw materials containing o-benzene and non-o-benzene.

3. When the equipment needs to be shut down for a long time.

If 75A catheter is used to produce reinforced tracheal intubation and other products, it is necessary to closely check the time and frequency of yellow and black spots and make records. This kind of product belongs to high-value and high-demand consumables, so special attention should be paid to the replacement of filter screen, which is generally controlled to be replaced every 20 hours, but it should also be based on the actual situation of the equipment. Filter screen is a means to increase fluid pressure to obtain better plasticizing effect. Generally, for materials with good thermal stability, the interval between yellow and black spots is long and easy to record.
