High Transparency Vacuum Casting Transparent PC

Kuwulutsa Kwapamwamba Kwambiri Kutayira Pakompyuta Yowonekera
  • High Transparency Vacuum Casting Transparent PC

Kufotokozera Kwachidule:

Kuponyera mu nkhungu za silikoni: zigawo zowonekera mpaka makulidwe a 10 mm: galasi lagalasi ngati magawo, mafashoni, zodzikongoletsera, zojambulajambula ndi zokongoletsera, magalasi owunikira.

• Kuwonekera kwambiri (kuyera madzi)

• Kupukuta kosavuta

• Kuchulukitsa kwachangu

• Kukana kwa U. V. kwabwino

• Easy processing

• Kukhazikika kwakukulu pansi pa kutentha

Processing Conditions

PX 5212 iyenera kugwiritsidwa ntchito pamakina oponyera vacuum ndikuponyedwa mu nkhungu ya silikoni yotenthedwa.Kutentha kwa 70 ° C kwa nkhungu ndikofunikira.

Kugwiritsa ntchito makina a vacuum:

• Kutenthetsa mbali zonse pa 20 / 25 ° C ngati mukusungira pa kutentha kochepa.

• Yesani isocyanate mu kapu yapamwamba (musaiwale kulola zinyalala zotsalira za kapu).

• Yesani polyol mu kapu yapansi (kapu yosakaniza).

• Mukatsuka mpweya kwa mphindi 10 pansi pa vacuum tsanulirani isocyanate mu polyol ndikusakaniza kwa mphindi zinayi.

• Tayani mu nkhungu ya silikoni, yotenthedwa kale pa 70°C.

• Ikani mu uvuni pa 70°C.

1 ora kwa 3 mm makulidwe

Tsegulani nkhungu, kuziziritsa mbali ndi wothinikizidwa mpweya.

Chotsani gawolo.

Chithandizo cha post kuchiritsa chikufunika kuti mupeze katundu womaliza (pambuyo pochotsa) 2h pa 70°C + 3h pa 80°C+ 2h pa 100°C.

Gwiritsani ntchito chojambula kuti mugwire gawolo panthawi ya chithandizo chamankhwala

ZINDIKIRANI: Zinthu zokumbukira zokhazikika zimathetsa kusinthika kulikonse komwe kumawonedwa panthawi yoboola.

Ndikofunika kuponyera PX 5212 mu nkhungu yatsopano popanda kuponyera utomoni kale mkati.
