Nqus Casting Txheej Txheem
• Tshav kub ntawm ob qhov chaw (isocyanate thiab polyol) ntawm 23 ° C nyob rau hauv cov ntaub ntawv khaws cia ntawm qhov kub thiab txias.
• Tseem ceeb : Ua kom lub zog A ua ntej txhua qhov hnyav.
• Ntsuas ob qho tib si.
• Tom qab degasing rau 10 feeb nyob rau hauv lub tshuab nqus tsev tov rau
1 feeb nrog PX 245
2 feeb nrog PX 245 / L
• Muab pov rau hauv lub tshuab nqus tsev hauv cov pwm silicone, yav tas los rhuab ntawm 70 ° C.
• Demould tom qab 30 feeb yam tsawg kawg nkaus ntawm 70 ° C (tso kom cov ntu kom txias ua ntej demoulding).
Kev Tiv Thaiv Kev Tiv Thaiv
Kev ceev faj txog kev noj qab haus huv thiab kev nyab xeeb yuav tsum tau ua thaum tuav cov khoom no:
• xyuas kom muaj cua zoo
• Hnav hnab looj tes thiab tsom iav kev nyab xeeb
