إجابات عملية على التحديات الشائعة في مواد البلاستيك

1343 سؤال
Q
DSTDP exudation to product surface
A
Q
DSTDP poor weather resistance
Q
Insufficient DSTDP addition amount, poor antioxidant effect
A
As a secondary antioxidant, DSTDP needs to be added in sufficient amount and combined with primary antioxidants
Material Analysis DSTDPaddition amountsecondary antioxidant1010/168 combinationmasterbatch method
Q
DSTDP product dimensional change during long-term storage
A
Dimensional change is caused by physical aging; annealing treatment and slight crosslinking are the measures to stabilize dimensions
Material Analysis DSTDP dimensional stabilityphysical agingannealingsecondary crystallizationslight crosslinking
Q
Poor interfacial bonding between DSTDP and filler
Q
Low Flexural Modulus of CMC
Q
Hydrolytic Aging of CMC
A
Hydrolytic aging is caused by polar groups being sensitive to water; selecting a low-polarity grade is the key
Material Analysis CMChydrolytic agingpolar groupsanti-hydrolysis stabilizerwaterproof coating
Q
Unstable Viscosity of CMC Solution Preparation
A
CMC viscosity stability is determined by molecular weight distribution and solution preparation conditions
Material Analysis CMC solution preparationviscosity fluctuationmolecular weight distributionsolution preparation temperaturefull stirring
Q
Large Smoke in CMC Processing
A
Large smoke is caused by volatilization of volatiles; temperature reduction and exhaust are the key
Material Analysis CMCprocessing smokevolatilesexhaust systemtemperature reduction
Q
Insufficient Toughness and Brittle Fracture of CMC
A
Insufficient toughness is caused by low molecular weight and coarse crystallization; selecting high MW is the key
