11636 سؤال
Q
Glass Fibre extruded film poor thickness uniformity
A
Film thickness uniformity needs coordinated optimization from three aspects: die design, gap adjustment and cooling

Q
Glass Fibre '2079851475616104452 warpage deformation
A
Warpage is caused by shrinkage differences and orientation stress; uniform mold temperature and holding pressure are key
Injection Molding Glass Fibre injectionwarpageshrinkage rateholding pressureannealing treatment
Q
Glass Fibre product yellowing after processing
A
Yellowing is caused by thermal-photo oxidation and metal catalysis; improving antioxidant system and UV absorber is key
Production & Quality Glass Fibre yellowingthermal oxidationantioxidantUV absorbermetal catalysis
Q
Glass Fibre film poor printing adhesion
A
Poor printing adhesion is caused by insufficient surface polarity; corona treatment and dedicated ink are key

Q
Glass Fibre film excessive heat shrinkage
A
Film heat shrinkage is caused by orientation freezing; reducing draw ratio and annealing treatment are key

Q
Glass Fibre '2079851475616104452 thick-wall bubbles
A
Thick-wall bubbles are comprehensively caused by insufficient holding pressure, moisture and poor venting
Material Drying Glass Fibre injectionbubblesholding pressurethick-wall productmold venting
Q
Glass Fibre extrusion pelletizing connected pellets
A
Connected pellets are caused by elastic recovery and low-temperature pelletizing; high-temperature water cutting and fast cutting are key

Q
Glass Fibre extrusion '2079851475616104457 parison severe sag
A
Parison sag is caused by low melt strength; slight crosslinking and wall thickness control are key

Q
Glass Fibre extrusion die buildup carbon deposit
A
Die carbon deposit is caused by thermal oxidation and untimely cleaning; PE flushing and timely cleaning are key
