Polypropylene (PP) yas ua khoom ua qauv
(1) crystalline plastics, me ntsis hygroscopicity, tawv tawg yuav tshwm sim, lub sij hawm ntev hu nrog kub kub tau decomposition
(2) zoo heev liquidity, txig ciam teb tus nqi nyob ib ncig ntawm 0.03 hli
(3) qhov txias ceev, qhov system thiab qhov txias cua txias yuav tsum muaj ntsis
(4) ntau yam ntawm molding shrinkage, shrinkage, deformation, shrinkage kab noj hniav, kev nyuaj siab, muaj zog ntawm kev sib deev
(5) xyuam xim kom tswj tau cov moulding temperature, tsis tshua muaj qhov kub thaum lub orientation yog cuab kev, tshwj xeeb tshaj yog cov siab muaj qis kub tsis tshua pom tseeb, pwm kub qis tshaj 50 ℃ plastic lackluster, yooj yim los tsim weld cim thiab ntws; tshaj li 90 ℃ thaum nws hnyav, deformation thiab yas nrig yuav tsum hnyav txheej tuab tuab, tsis txhob sib kis, ntse pob, los tiv thaiv kev ntxhov siab
