Processing Conditions

Kutenthetsa mbali zonse ziwiri (isocyanate ndi polyol) pa 73°F(23°C) ngati zasungidwa pa kutentha kochepa.

Zofunika : Gwirani mwamphamvu gawo A musanayese sikelo.

Wezani mbali zonse ziwiri.

Pambuyo degassing kwa mphindi 10 pansi zingalowe kusakaniza kwa

Mphindi 1 ndi PX 226-226

Mphindi 2 ndi PX 226-226/L

Ponyani pansi pa vacuum mu nkhungu ya silikoni, yotenthedwa kale pa 158°F(70°C).

Onjetsani pambuyo pa 25 - 60 mphindi zochepa pa 158 ° F (70 ° C) (lolani gawolo kuti lizizire pansi musanagwetse).

Kusamalira Chitetezo
