Utoto wa Pulasitiki: Ubwino Waikulu wa Mitundu Yosiyanasiyana ya Utoto
Utoto womwe umagwiritsidwa ntchito popaka utoto wa pulasitiki uyenera kukwaniritsa zofunikira zina, monga kukhazikika kwamafuta, kusungunuka, komanso kugwirizanitsa ndi ma polima. M'munsimu muli mitundu yabwino kwambiri ya utoto yamapulasitiki, limodzi ndi maubwino awo ndi ntchito zawo.
1.Mitundu Yosungunulira
Ubwino:
-Kusungunuka Kwabwino Kwambiri mu Pulasitiki: Sungunulani bwino mu ma polima omwe si a polar (mwachitsanzo, PS, ABS, PMMA).
-Kukhazikika Kwapamwamba Kwambiri (> 300 ° C): Yoyenera kutentha kwambiri (kuumba jekeseni, extrusion).
- Mitundu Yowonekera & Yowoneka bwino: Ndi yabwino pazinthu zapulasitiki zowonekera kapena zowoneka bwino (mwachitsanzo, magalasi, zopakira).
-Kuwala Kwabwino: Kusagwirizana ndi kuwala kwa UV muzinthu zambiri.
Kagwiritsidwe Ntchito Kamodzi:
- Acrylics (PMMA), polystyrene (PS), polycarbonate (PC), ndi ma polyesters ena.
Malingaliro athu:
Yellow Yellow 21,Zosungunulira Red 8,Zosungunulira Red 122,Solvent Blue 70,Solvent Black 27,Yellow Yellow 14,Zosungunulira Orange 60,Zosungunulira Red 135,Zosungunulira Red 146,Solvent Blue 35,Solvent Black 5,Solvent Black 7,Mtundu Wosungunulira Yellow 21,Zosungunulira Orange 54 Kapangidwe,Mtundu Wosungunulira wa Orange 54ndi zina.
2. Mitundu Yoyambira (Cationic)
Ubwino:
-Fluorescent Yabwino Kwambiri & Zazitsulo Zachitsulo: Pangani mitundu yopatsa chidwi.
-Kugwirizana Kwabwino kwa Acrylics & Modified Polymers: Amagwiritsidwa ntchito m'mapulasitiki apadera.
Zolepheretsa
- Zochepa pa ma polima enieni (mwachitsanzo, ma acrylic) chifukwa chazovuta.
Kagwiritsidwe Ntchito Kamodzi:
- Mapulasitiki okongoletsera, zoseweretsa, ndi mapepala a acrylic.
Malingaliro athu:
Direct Yellow 11, Direct Red 254, Direct Yellow 50, Direct Yellow 86, Direct Blue 199, Direct Black 19 , Direct Black 168, Choyambirira Brown 1, Mtundu wa Violet 1,Mtundu wa Violet 10, Mtundu wa Violet 1ndi zina.
Kodi mungakonde malingaliro amtundu winawake wapulasitiki kapena ntchito?
