I-High Transparency Vacuum Casting Transparent PC

Incazelo emfushane:

Ukusakaza ngesikhunta se-silicone: izingxenye ze-prototype ezikhanyelayo kuze kube ugqinsi oluyi-10 mm: ingilazi yekristalu njengezingxenye, imfashini, ubucwebe, izingxenye zobuciko kanye nomhlobiso, amalensi okukhanyisa.

• Ukuba sobala okuphezulu (ukuhlanzeka kwamanzi)

• Ukupholisha kalula

• Ukunemba okuphezulu kokukhiqiza

• Ukumelana okuhle kwe-U. V.

• Ukucubungula okulula

• Ukuzinza okuphezulu ngaphansi kwezinga lokushisa

Izimo Zokucubungula

I-PX 5212 kumele isetshenziswe kuphela emshinini wokulahla i-vacuum futhi ifakwe esikhunjini se-silicone esishiswe ngaphambilini.Inhlonipho engu-70°C yesikhunta ibalulekile.

Ukusetshenziswa komshini wokukhipha i-vacuum:

• Shisisa zombili izingxenye ku-20/25°C uma uzigcina emazingeni okushisa aphansi.

• Kala i-isocyanate enkomishini engaphezulu (ungakhohlwa ukuvumela udoti wenkomishi osele).

• Kala i-polyol enkomishini engezansi (inkomishi yokuxuba).

• Ngemva kokukhipha umoya imizuzu eyi-10 ngaphansi kwevacuum thela i-isocyanate ku-polyol bese uxuba imizuzu emi-4.

• Faka kusikhunta se-silicone, ngaphambilini ibishiswe ku-70°C.

• Faka kuhhavini ongu-70°C.

Ihora elingu-1 ukujiya okungu-3 mm

Vula isikhunta, ukupholisa ingxenye ngomoya ocindezelweyo.

Susa ingxenye.

Ukwelashwa ngemuva kokwelapha kuyadingeka ukuze uthole izakhiwo zokugcina (emva kokudilizwa) 2h ku-70°C + 3h ku-80°C+ 2h ku-100°C

Sebenzisa i-fixture ukuze ubambe ingxenye ngesikhathi sokwelashwa ngemuva kokwelapha

QAPHELA: Izinto zenkumbulo enwebekayo zisusa noma yikuphi ukuguquguquka okubonwa ngesikhathi sokudilizwa.

Kubalulekile ukuphonsa i-PX 5212 esikhunjeni esisha ngaphandle kokuphonsa inhlaka ngaphambili ngaphakathi.

Izimo Zokugcina

Isikhathi seshelufu sazo zombili izingxenye siyizinyanga eziyi-12 endaweni eyomile futhi ezitsheni zazo zasekuqaleni ezingavuliwe ezingeni lokushisa eliphakathi kuka-10 no-20°C.Gwema ukugcina isikhathi eside ezingeni lokushisa elingaphezu kuka-25°C.

Noma yiliphi ithini elivuliwe kufanele livalwe ngokuqinile ngaphansi kwe-nitrogen eyomile.

Ukuphatha Izinyathelo Zokuqapha

Izinyathelo zokuphepha ezijwayelekile kufanele zibhekwe lapho uphatha le mikhiqizo :

Qinisekisa umoya omuhle

Gqoka amagilavu, izibuko zokuphepha nezingubo ezingangeni manzi

Ukuze uthole ulwazi olwengeziwe, sicela ubheke ishidi ledatha yokuphepha komkhiqizo.
