IBanga eliPhezulu leMathiriyeli yeVacuum Casting TPU

IBanga eliPhezulu leMathiriyeli yeVacuum yokuCasa iTPU eFakelweyo nguMfanekiso
  • IBanga eliPhezulu leMathiriyeli yeVacuum Casting TPU

Inkcazelo emfutshane:

I-Hei-Cast 8400 kunye ne-8400N zizinto ezi-3 zodidi lwe-polyurethane elastomers ezisetyenziselwa ukubumba usetyenziso lwe-vacuum ezinezi mpawu zilandelayo:

(1) Ngokusetyenziswa kwe "C component" ekuqulunqweni, nabuphi na ubunzima kuluhlu lwe-A10 ~ 90 lunokufumaneka / lukhethwe.
(2) I-Hei-Cast 8400 kunye ne-8400N iphantsi kwi-viscosity kwaye ibonisa ipropati ehamba phambili.
(3) I-Hei-Cast 8400 kunye ne-8400N zonyango kakuhle kakhulu kwaye ibonisa ukuphinda-phinda okugqwesileyo.

8. Inkqubo yokubumba iVacuum

(1) Ukulinganisa ubunzima
Gqiba isixa se "C component" ngokobunzima obunqwenelayo kwaye wongeze kwi A component.
Viyisha umlinganiselo ofanayo ngobunzima becandelo B njengecandelo A kwikomityi eyahlukileyo kuthathelwa ingqalelo isixa esinokuthi sishiyeke ekomini.

(2) I-pre-degassing
Yenza i-pre-degassing kwi-degassing room malunga nemizuzu emi-5.
Degass kangangoko ufuna.
Sincoma ukuba i-degass emva kokufudumeza imathiriyeli kubushushu bolwelo obungama-25 ~ 35°C.

(3) Ubushushu be-resin
Gcina ubushushure of25 ~ 35 °C ngenxa zombini A(equlathe C icandelo) kwaye B  icandelo.
Xa ubushushu bezinto eziphathekayo buphezulu, ubomi bembiza yomxube buya kuba bufutshane kwaye xa ubushushu bezinto buphantsi, ubomi bembiza yomxube buya kuba bubude.

(4) Ubushushu bokungunda
Gcina ubushushu be-silicone ngundo eshushu ngaphambili ukuya kuma-60 ~ 700C.
Ubushushu obuphantsi kakhulu bokungunda bunokubangela ukunyangwa okungafanelekanga okukhokelela kwiimpawu zomzimba ezisezantsi.Amaqondo obushushu okungunda kufuneka alawulwe ngokuchanekileyo njengoko aya kuchaphazela ukuchaneka komgangatho wenqaku.

(5) Ukuphosa
Izikhongozeli zibekwe ngendlela yokubaB  icandelo  is  yongezwe  to  A icandelo (coukuhlamba C icandelo).
Faka i-vacuum kwigumbi kunye ne-de-gass Icandelo le-5 ~ 10 imizuzungelixa it is zishukunyiswa ngamaxesha athile.                                                                                                 
Yongeza B icandelo to A icandelo(equlathe C icandelo)kwaye ugxobhoze i-30 ~ 40 imizuzwana kwaye uphose umxube ngokukhawuleza kwi-silicone mold.
Khupha i-vacuum kwi-1 kunye nesiqingatha somzuzu emva kokuqalisa ukuxuba.

(6) Ukunyanga imeko
Beka i-mold egcweleyo kwi-oven ye-thermostatic ye-60 ~ 700C yemizuzu engama-60 ye-Type A yokuqina kwe-90 kunye nemizuzu ye-120 ye-Type A yokuqina kwe-20 kunye ne-demold.
Yenza umsebenzi wokunyanga nge-600C iiyure ezi-2 ukuya kwezi-3 ngokuxhomekeke kwiimfuno.

9. Itshati equkuqelayo ye-vacuum casting

 

10. Amanyathelo okuthintela ukuphatha

(1) Njengoko yonke icandelo le-A, B kunye no-C libuthathaka emanzini, ungaze uvumele amanzi ukuba angene kwizinto eziphathekayo.Kwakhona zikhwebule kwizinto ezidibana ixesha elide nokufuma.Vala isikhongozeli siqinile emva kokusetyenziswa ngakunye.

(2) Ukungena kwamanzi kwicandelo le-A okanye le-C kunokukhokelela ekuveliseni amaqamza omoya amaninzi kwimveliso enyangisiweyo kwaye ukuba oku kunokwenzeka, sincoma ukutshisa icandelo elingu-A okanye le-C ukuya kuma-80°C kunye ne-degass ngaphantsi kwe-vacuum malunga nemizuzu eyi-10.

(3) Icandelo liya kuba ngumkhenkce kumaqondo obushushu angaphantsi kwe-15°C.Fudumeza ukuya kwi-40 ~ 50 ° C kwaye usebenzise emva kokuyishukumisa kakuhle.

4Musa ukusebenzisa izinto eziphathekayo xa ilahlekelwe yinto ecacileyo okanye ibonise naluphi na ukuqina njengoko ezi zixhobo ziya kukhokelela kwiimpawu zomzimba eziphantsi kakhulu.

(5) Ukufudumeza ixesha elide lecandelo le-B kumaqondo okushisa angaphezu kwama-50 ° C kuya kuchaphazela umgangatho wecandelo le-B kwaye amathini anokunyuswa ngokunyuka koxinzelelo lwangaphakathi.Gcina kwiqondo lokushisa.

 

11. Izilumkiso kuKhuseleko kunye noCoceko

(1) Icandelo B liqulethe ngaphezu kwe-1% ye-4,4'-Diphenylmethane diisocyanate.Faka i-exhaust yendawo ngaphakathi kwivenkile yomsebenzi ukuze ukhusele ukungena komoya okulungileyo.

(2) Lumka ukuba izandla okanye ulusu aludibani ngokuthe ngqo nezinto ezikrwada.Xa udibana, hlamba ngesepha namanzi ngokukhawuleza.Isenokucaphukisa izandla okanye ulusu ukuba zishiywe zidibene nemathiriyeli ekrwada ixesha elide.

(3) Ukuba izinto ezikrwada zingena emehlweni, hlambulula ngamanzi aqukuqelayo kangangemizuzu eli-15 uze ubize ugqirha.

(4) Faka umbhobho wempompo yokufunxa ukuqinisekisa ukuba umoya uphelile ngaphandle kwendawo yokusebenzela.
