Superior Comprehensive Properties Vacuum Casting PA efana

Incazelo emfushane:

Izosetshenziswa ngokusakazwa kwe-vacuum ekubunjweni kwe-silicone ekwenzeni izingxenye ze-prototype kanye nokuhlekwa ngezakhiwo ezisebenza ngomshini ezifana ne-thermoplastics njenge-polystyrene ne-ABS egcwele.

Izimo Zokucubungula

Shisisa zombili izingxenye (i-isocyanate ne-polyol) ku-73°F(23°C) uma zigcinwa ezingeni lokushisa eliphansi.

Okubalulekile : Nyakazisa ngamandla ingxenye A ngaphambi kwesisindo ngasinye.

Kala izingxenye zombili.

Ngemva degassing imizuzu 10 ngaphansi vacuum mix for

Iminithi elingu-1 nge-PX 226-226

Faka ngaphansi kwe-vacuum kusikhunta se-silicone, ngaphambilini ebishiswe ku-158°F(70°C).

Khomba ngemva kwemizuzu engu-25 - 60 ubuncane ku-158°F(70°C) (vumela ingxenye ukuthi iphole ngaphambi kokudilizwa).

Ukuphatha Izinyathelo Zokuqapha

Izinyathelo zokuphepha ezijwayelekile kufanele zibhekwe lapho uphatha le mikhiqizo :

Qinisekisa umoya omuhle

Gqoka amagilavu, izibuko zokuphepha kanye nezimpahla ezingenwa amanzi.

Ukuze uthole ulwazi olwengeziwe, sicela ubheke ishidi ledatha yokuphepha.
