High Mechanical Mphamvu Kuwala Kulemera Vuto Vuto Akuponya PP ngati

High Mechanical Mphamvu Kuwala Kulemera Kutaya Vuto Kuponya PP ngati Chithunzi Chowonetsedwa
  • High Mechanical Mphamvu Kuwala Kulemera Vuto Vuto Akuponya PP ngati

Kufotokozera Kwachidule:

Kuponyera kuti apange zigawo za prototype ndi zoseketsa zokhala ndi zida zamakina monga PP ndi HDPE, monga gulu la zida, bumper, bokosi la zida, chivundikiro ndi zida zotsutsa kugwedezeka.

• 3-zigawo za polyurethane zoponyera vacuum

• Kutalika kwambiri

• Easy processing

• Flexural modulus chosinthika

• Kukana kwakukulu, palibe chosweka

• Kusinthasintha kwabwino

ZOCHITA ZOCHITIKA (Makina oponyera vacuum)

• Preheat isocyanate mpaka 23 - 30 ° C ngati ikusungidwa pansi pa 20 ° C.

• Preheat polyol ndi gawo C mpaka 40°C musanagwiritse ntchito.M'pofunika kusonkhezera polyol mpaka mitundu yonse ndi mbali kukhala homogeneous.

• Yezerani zigawozo molingana ndi chiŵerengero chosakaniza, ikani isocyanate mu kapu yapamwamba, onjezerani gawo C mu polyol ku premix.

Thirani isocyanate mu polyol (yomwe ili ndi Gawo C) ndipo sakanizani kwa mphindi 1 - 2 mutatha kuchotsa mpweya kwa mphindi 10 mosiyana.

• Ikani mu vacuum mu nkhungu ya silikoni yotenthedwa mpaka 70°C.

• Onjetsani pakatha mphindi 60 - 90 pa 70°C (Gawo C likamagwiritsidwa ntchito kwambiri, pafunikanso nthawi yotalikirapo).
