Yepamusoro Giredhi Material Vacuum Casting TPU

Tsanangudzo Pfupi

Hei-Cast 8400 uye 8400N 3 chikamu chemhando ye polyurethane elastomers inoshandiswa pakuputira vacuum molding application ine zvinotevera maitiro:

(1) Kuburikidza nekushandiswa kwe "C chikamu" mukugadzirisa, chero kuoma kwemhando yeRudzi A10 ~ 90 kunogona kuwanikwa / kusarudzwa.
(2) Hei-Cast 8400 uye 8400N yakaderera mu viscosity uye inoratidza yakanakisa kuyerera pfuma.
(3) Hei-Cast 8400 uye 8400N inorapa zvakanaka uye inoratidza yakanakisa rebound elasticity.

8. Vacuum Molding Process

(1) Kuyera
Sarudza huwandu hwe "C chikamu" zvinoenderana nekuoma kwaunoda uye wowedzera kune A chikamu.
Weresa huremu hwakafanana nehuremu hwechikamu B sechikamu cheA mune imwe kapu uchitarisa huwandu hungasara mumukombe.

(2) Pre-degassing
Ita pre-degassing mu degassing chamber kwemaminitsi mashanu.
Degass zvakanyanya sezvaunoda.
Isu tinokurudzira kubvisa gasi mushure mekupisa zvinhu kune tembiricha yemvura ye25 ~ 35 ° C.

(3) Kupisa kwe resin
Keep temperature of25~35°C nokuti zvose A(zvine C chikamu) uye B chikamu.
Kana tembiricha yechinhu ichikwira, hupenyu hwehari yemusanganiswa hunova hupfupi uye kana tembiricha yezvinhu yadzikira, hupenyu hwehari yemusanganiswa huchareba.

(4) Mold tembiricha
Chengetedza tembiricha yesilicone mold pre-yakapisa kusvika 60 ~ 700C.
Kunyanya kudzikira mold tembiricha inogona kukonzera kusapora kukonzeresa kuderera kwemuviri.Kupisa kwe mold kunofanirwa kudzorwa nemazvo sezvo zvichizokanganisa kurongeka kwechinyorwa.

(5) Kukandira
Containers inoiswa nenzira yekutiB chikamu is akawedzera to A chikamu (containing C chikamu).
Isa vacuum mukamuri uye de-gasi Chikamu che5 ~ 10 maminetsiapo it is kushungurudzwa nguva nenguva.
Wedzera B chikamu to A chikamu(zvine C chikamu)uye simbisa kwe30 ~ 40 seconds uye wobva wakanda musanganiswa wacho nekukurumidza musilicone mold.
Bvisa vacuum mu1 nehafu yeminiti mushure mekutanga kusanganisa.

(6) Kurapa mamiriro
Isa mold yakazadzwa muhovhoni ye thermostatic ye60 ~ 700C kwemaminetsi makumi matanhatu eRudzi A kuomarara 90 uye kwemaminetsi zana nemakumi maviri eRudzi A kuoma makumi maviri uye demold.
Ita post kurapa pa600C kwe2 ~ 3 maawa zvichienderana nezvinodiwa.

9. Chati inoyerera yevacuum casting

10. Kungwarira pakubata

(1) Sezvo ese A, B uye C chikamu chinonzwa kumvura, usambobvumira mvura kupinda muchinhu.Uyewo rega kubva kune zvinhu zvinouya kwenguva yakareba zvakasangana nehunyoro.Vhara mudziyo zvakasimba mushure mekushandisa kwega kwega.

(2) Kupinda kwemvura muchikamu cheA kana C kunogona kutungamirira kukugadzirwa kwemhepo yakawanda muchigadzirwa chakarapwa uye kana izvi zvikaitika, tinokurudzira kupisa chikamu cheA kana C kusvika ku80 ° C uye kubvisa pasi pevacuum kwemaminitsi gumi.

(3) Chikamu chinoomesa chando pane tembiricha iri pasi pe15°C.Kupisa kusvika 40 ~ 50 ° C uye shandisa mushure mekuizunza zvakanaka.

4Usashandise zvinhu kana zvarasa kujeka kana zvaratidza kuomarara sezvo zvinhu izvi zvichizotungamira kune yakaderera zvinhu zvemuviri.

(5) Kupisa kwenguva refu kwechikamu cheB pane tembiricha inopfuura 50 ° C kuchakanganisa kunaka kwechikamu cheB uye makani anogona kukwidziridzwa nekuwedzera kwemukati.Chengetedza pane tembiricha yekamuri.

11. Chengetedzo Mukuchengetedza uye Hutsanana

(1) B chikamu chine zvinopfuura 1% ye4,4'-Diphenylmethane diisocyanate.Isa mhepo yemuno mukati mechitoro chebasa kuti uchengetedze mhepo yakanaka yemhepo.

(2) Chenjerera kuti maoko kana ganda hazvisi kusangana zvakananga nemidziyo.Kana masangana, gezai nesipo nemvura nekukasika.Inogona kutsamwisa maoko kana ganda kana vakasara vachisangana neyakagadzirwa kwenguva yakareba.

(3) Kana zvinhu zvisina kubikwa zvikapinda mumaziso, sukurudza nemvura inoyerera kwemaminetsi gumi nemashanu wodaidza chiremba.

(4) Isa duct yevacuum pombi kuti uve nechokwadi chekuti mweya wapera kune kunze kwechitoro chebasa.
