1343 질문
Q
EMA processing temperature fluctuation
A
Temperature fluctuation is caused by improper temperature control system; PID tuning and heater band replacement are key
Material Analysis EMA temperature fluctuation PID tuning heater band thermocouple
Q
Insufficient EMA tensile strength
A
Insufficient tensile strength is caused by molecular weight and poor interface; selecting high MW grade is key
Material Analysis EMA tensile strength molecular weight coupling agent orientation control
Q
EMA hardness too high
A
High hardness is caused by crystallization and filler; adjusting cooling and filler is key
Material Analysis EMA hardness too high crystallinity filler amount plasticizer
Q
Low EMA elongation at break
A
Low elongation at break is caused by low molecular weight and orientation; selecting high MW and reducing orientation are key
Material Analysis EMA elongation at break molecular weight orientation control crosslinking degree
Q
Fast EMA thermal aging
A
Thermal aging is caused by thermo-oxidation; completing the antioxidant system is key
Material Analysis EMA thermal aging thermo-oxidation antioxidant high molecular weight
Q
EMA incompatible with lubricant
A
Lubricant incompatibility causes exudation; selecting compatible lubricant is key
Material Analysis EMA lubricant exudation compatibility internal lubricant dosage control
Q
EMA flame retardancy not up to standard
Q
Fast UV aging of EMA
A
Fast UV aging is caused by photo-oxidation; UV absorber and HALS are key
Material Analysis EMA UV aging UV absorber HALS radical scavenging
Q
Unstable shrinkage rate of EMA
A
Unstable shrinkage rate is caused by batch differences and temperature fluctuation; raw material and temperature control are key
Material Analysis EMA shrinkage rate batch difference stable temperature control crystallization consistency
Q
EMA Poor Weather Resistance
A
Poor weather resistance is caused by photo-oxidation; UV+HALS+antioxidant triple protection is key
Material Analysis EMA weather resistance UV absorber HALS photo-oxidation
