1, Lub hom phiaj thiab kev cuam tshuam ntawm kev tswj qhov kub thiab txias ntawm lub plhaub yas formability
Pwm core kub ho cuam tshuam qhov tsos, lub cev muaj zog thiab molding voj voog ntawm cov khoom molded. Nyob rau hauv cov txheej txheem molding, nws yog ntshaw kom ua kom cov tub ntxhais kub ntawm lub plhaub yas qis kom lub sij hawm txhaj tshuaj, tab sis lub voj voog molding muaj feem xyuam rau cov duab ntawm cov khoom molded (cov qauv tseem ceeb) thiab hom khoom tiav kuj nyob ntawm qhov yuav tsum tau ua kom cov tub ntxhais filling kub.
ABS yas muaj qhov kub molding siab, thiab nws cov pwm kub feem ntau yog hloov kho ntawm 25-70 degree . Thaum tsim cov khoom loj, qhov kub ntawm cov pwm ruaj khov (pem hauv ntej pwm) feem ntau yog li 5 degree siab dua li cov pwm txav (rov qab pwm). (pwm kub yuav cuam tshuam rau qhov kawg ntawm cov khoom yas, thiab qhov kub thiab txias yuav ua rau kom tiav tiav)
2, Kho cov crystallinity ntawm cov khoom tsim los tswj qhov kub thiab txias.
Cov ntaub ntawv crystalline, xws li polysulfide (nylon), polyacetate tsiaj rog, polypropylene, thiab lwm yam. Cov tub ntxhais kub siab dua feem ntau yuav tsum tau kho crystallinity thiab txhim kho cov khoom siv kho tshuab.
3, ABS yas yuav tsum tsis txhob nyob twj ywm hauv qhov kub-kub ntev ntev (tsawg dua 30 feeb), txwv tsis pub nws yooj yim rau decompose thiab tig daj.
