Codsiga
Sida hal nooc oo ka mid ah dab-demiska deegaanka-saaxiibtinimo, waxaa loo isticmaali karaa wax ka beddelka dab-dejinta ololka joogtada ah ee polyester-ka, iyo awoodda dab-dejinta polyester-ka waxay la mid tahay PET, sidaas darteed waxaa loo isticmaali karaa dhammaan noocyada nidaamka wareegga, oo leh astaamo heerkul aad u fiican. xasilloonida, majirto qallafsanaan inta lagu jiro wareegga iyo ur la'aan. Waxaa loo isticmaali karaa dhammaan qaybaha codsiga ee PET si loo hagaajiyo awoodda antistatic ee polyesterka. Qiyaasta kobolymerization ee PTA iyo EG waa 2.5 ~ 4.5%, qiyaasta fosfooraska ee xaashida polyester-ka ee ololka dib u dhigaya waa 0.35-0.60%, iyo LOI ee alaabada dib u dhigista ololku waa 30 ~ 36%.
Xidhmada
