Ukusebenza Okuhle Izakhiwo Ezizigcoba Ngayo I-Vacuum Casting POM

Ukusebenza Okuhle Izakhiwo Ezizigcoba Ngayo Ivacuum Ukusakaza kwe-POM Isithombe Esifakiwe

Incazelo emfushane:

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

• High flexural modulus of nokunwebeka

• Ukunemba okuphezulu kokukhiqiza

• Itholakala ku-reactivity ezimbili (4 kanye ne-8 min.)

• Ingafakwa umbala kalula nge-CP pigments

• Ukudiliza ngokushesha

Imibandela Yokucubungula I-Vacuum Casting

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

• Okubalulekile : Nyakazisa ngamandla ingxenye A ngaphambi kokukala ngakunye.

• Kala izingxenye zombili.

• Ngemva kokukhipha umoya imizuzu eyi-10 ngaphansi kwe-vacuum mix for

Iminithi elingu-1 nge-PX 245

2 amaminithi nge-PX 245/L

• Faka ngaphansi kwe-vacuum kusikhunta se-silicone, ngaphambilini ebishiswe ku-70°C.

• Khipha ngemva kwemizuzu engama-30 ubuncane ku-70°C (vumela ingxenye ukuthi iphole ngaphambi kokudilizwa).

Ukuphatha Izinyathelo Zokuqapha

Izinyathelo ezijwayelekile zempilo nokuphepha kufanele zibhekwe lapho uphatha le mikhiqizo:

• qinisekisa ukungena komoya okuhle

• Gqoka amagilavu nezibuko zokuphepha

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