1. Kutulutsa Oxidize ya Brown
Cholinga:
Mankhwala amawonjezera pamwamba pa mkuwa kuti apange wosanjikiza wa oxide (brown cuprous oxide), womwe umawonjezeranso malo a pamwamba kuti uwonjezere mphamvu yolumikizana.
Chenjezo:
1. Pambuyo pothira brown oxidizing, bolodi liyenera kudzazidwa mwachangu ndikupakidwa laminated. Ngati lisiyidwa kwa nthawi yayitali, limakhala ndi chinyezi ndipo limasakanikirana ndi CO2 mumlengalenga kuti lipange carbonic acid, yomwe imasungunula brown oxide layer, zomwe zimakhudza mphamvu yake yolumikizirana ndikuwonjezera chiopsezo cha delamination.
2. Bolodi yokhala ndi mkuwa wokhuthala (≥2oz) ndi bolodi lopanda kanthu liyenera kuphikidwa kuti lichotse chinyezi chochuluka.
Magawo ophikira: 120℃±5℃×120 min
2. Mulu wa zinthu zoyambira
Cholinga:
Malinga ndi malangizo a MI, phatikizani bolodi lapakati ndi PP pamodzi.
Kapangidwe kofala ka bolodi la magawo anayi
3. Kukweza bolodi
Cholinga:
Ikani gulu lililonse la matabwa okonzedwa kale komanso opindika pawokha pa mbale yachitsulo motsatizana, nthawi zambiri ndi matabwa 4-6pnl opangira pa mbale iliyonse.
4. Kupaka utoto
Cholinga:
Kudzera mu kutentha ndi kupanikizika kwina, njira yolimba ya PP kuchokera ku semi-solid kupita ku madzi imachitika kuti igwirizanitse bolodi lapakati, PP ndi zojambulazo zamkuwa pamodzi.
5. Kutsitsa katundu
Cholinga:
Sulani bolodi lopangidwa ndi laminated kukhala ma PNL, ndipo muziziziritse.
6. Kuboola kwa X-Ray
Cholinga:
Gwirani malo a chithunzi chamkati mwa chithunzi pogwiritsa ntchito X-Ray radiation yaChipangizo cha X-Ray, kenako bowolani mabowo oikamo zinthu kudzera mu kubowola kwamakina.
