إجابات عملية على التحديات الشائعة في مواد البلاستيك

11636 سؤال
Q
POE extrusion die material buildup carbon deposit
A
Die carbon deposit is caused by thermal oxidation and untimely cleaning; PE flushing and timely cleaning are key
Extrusion & Post POE extrusiondie carbon depositPE flushingresidence zonethermal oxidation
Q
POE blended with incompatible resins, delamination
A
Blends with large polarity differences require reactive compatibilizers to form chemical bonding at the interface to solve it

Q
POE extrusion pelletizing strand sticking
A
Strand sticking is caused by elastic recovery and low-temperature pelletizing; high-temperature water cutting and fast cutting are the key

Q
Severe parison sag in POE extrusion '2079851475616104457
A
Parison sag is caused by low melt strength; slight crosslinking and wall thickness control are the key

Q
POE products yellowing after processing
Q
Long-term storage dimensional change of POE products
A
Dimensional change is caused by physical aging; annealing treatment and slight crosslinking are measures to stabilize dimensions

Q
Poor interfacial bonding between POE and filler
Q
POE extrusion melt fracture
Q
POE '2079851475616104452 thick-wall bubbles
A
Thick-wall bubbles are caused by a combination of insufficient holding pressure, moisture and poor venting
