Txheej txheem txheej txheem
Thaum tshav kub kub ntawm ob qhov chaw (isocyanate thiab polyol) ntawm 73 ° F (23 ° C) nyob rau hauv cov ntaub ntawv ntawm cia ntawm qhov kub thiab txias.
Tseem ceeb : Ua kom muaj zog ntu A ua ntej txhua qhov hnyav.
Ntsuas ob ntu.
Tom qab degassing rau 10 feeb nyob rau hauv lub tshuab nqus tsev tov rau
1 feeb nrog PX 226-226
2 feeb nrog PX 226-226 / L
Cam khwb cia nyob rau hauv lub tshuab nqus tsev nyob rau hauv ib tug silicone pwm, yav tas los rhuab ntawm 158 ° F (70 ° C).
Demold tom qab 25 - 60 feeb yam tsawg kawg nkaus ntawm 158 ° F (70 ° C) (tso rau qhov kom txias ua ntej demolding).
