PROCESSING (Lub tshuab nqus tsev casting)
•Lub tshuab nqus tsev casting rau hauv silicone pwm.
•Ob leeg ntu muaj to be ua tiav at a kub saum toj no +18 °C.
• Tseem ceeb : Rehomogenize ib feem B ua ntej txhua hnyav.
•Degas txhua ib feem ua ntej siv.
•Sib tov rau 45 vib nas this kwv yees.
•Ntxig in a pwm ua ntej-cua sov at 40 °C yam tsawg kawg nkaus.
•Tso cai to kho 45 to 75 feeb at 70 °C ua ntej demoulding
•Nqa tawm tus raws li thermal kev kho mob : 1 hr at 100 °C + 2 hr at 110 °C or ntau if ua tau.
NOTA : Tom qab demoulding it is tsis yog tsim nyog to siv a conformter to tswj tus ib feem in tus qhov cub thaum tus ncej
KEV KOM ZOO
Ib txwm noj qab haus huv thiab kev nyab xeeb cov kev ceev faj yuav tsum be pom thaum tuav cov no cov khoom :
•xyuas kom meej zoo qhov cua
•hnav hnab looj tes thiab kev nyab xeeb tsom iav
Rau ntxiv cov ntaub ntawv, thov sab laj tus khoom kev nyab xeeb cov ntaub ntawv daim ntawv.
