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.

Onetsetsani mpweya wabwino

Valani magolovesi, magalasi oteteza chitetezo ndi zovala zosalowa madzi

Kuti mumve zambiri, chonde onani tsamba lachitetezo chamankhwala.
