  • I-Vacuum ePheleleyo ephezulu yokuCasa iPC eNgaphandle

Inkcazelo emfutshane:

Ukuphosa kwimold ye-silicone: iinxalenye zeprototype ezicacileyo kude kube yi-10 mm ubukhulu: iglasi yekristale efana namalungu, ifashoni, ubucwebe, ubugcisa kunye neenxalenye zokuhombisa, iilensi zezibane.

• Ukukhanya okuphezulu (ukucoceka kwamanzi)

• Ukugudisa ngokulula

• Ukuchaneka okuphezulu kokuzala

• Ukuxhathisa okuhle kwe-U. V

• Ukusetyenzwa lula

• Ukuzinza okuphezulu phantsi kobushushu

Iimeko Zokusebenza

I-PX 5212 kufuneka isetyenziswe kuphela kumatshini wokukhupha i-vacuum kwaye ifakwe kwi-silicone mold yangaphambili.Intlonipho yobushushu obungama-70°C kumngundo iyimfuneko.

Ukusetyenziswa komatshini wokukhupha:

• Fudumeza omabini la malungu kwi-20/25°C xa ugcinwa kwiqondo lobushushu elisezantsi.

• Viyisha i-isocyanate kwikomityi ephezulu (ungalibali ukuyivumela inkunkuma yekomityi eshiyekileyo).

• Beka umlinganiselo wepolyol kwikomityi esezantsi (kwikomityi yokuxuba).

• Emva kokukhupha umoya kangangemizuzu eli-10 phantsi kwevacuum galela isocyanate kwipolol kwaye udibanise imizuzu emi-4.

• Faka kwi-silicone ukungunda, ngaphambili ifudunyezwe kwi-70 ° C.

• Faka kwi-oven ekwi-70°C.

Iyure e-1 kwi-3 mm ubukhulu

Vula isikhunta, ukupholisa inxalenye ngomoya ocinezelweyo.

Susa inxalenye.

Unyango lokunyanga emva kokunyanga luyafuneka ukufumana iipropati zokugqibela (emva kokudilizwa) 2h kwi-70 ° C + 3h kwi-80 ° C + 2h kwi-100 ° C

Sebenzisa i-fixture yokusingatha inxalenye ngexesha lonyango lokunyanga

QAPHELA: Imathiriyeli yenkumbulo ethambileyo isusa naluphi na utshintsho olubonwe ngexesha lokudilizwa.

Kubalulekile ukuphosa i-PX 5212 kubumba olutsha ngaphandle kokuphosa i-resin ngaphambili ngaphakathi.

Iimeko zokuGcina

Ubomi beshelufu yawo omabini la malungu ziinyanga ezili-12 kwindawo eyomileyo kwaye kwizikhongozeli zazo zokuqala ezingavulwanga kubushushu obuphakathi kwe-10 ne-20°C.Kuphephe ukugcina ixesha elide kwiqondo lobushushu elingaphezu kwama-25°C.

Nayiphi na inkonkxa evulekileyo kufuneka ivalwe ngokuqinileyo phantsi kwenitrogen eyomileyo.
