Imikhiqizo
WG-02-0018-01 Ikesi Elisekhanda
Isici soMkhiqizo
Ukukhishwa kwegwebu elilahlekile (okubuye kwaziwe ngokuthi ukubunjwa kwesikhunta sangempela) kwenziwa ngepulasitiki eyigwebu (EPS, STMMA noma EPMMA) impahla ye-polymer ibe isikhunta sangempela esinesakhiwo nosayizi ofanayo ncamashi nezingxenye okufanele zikhiqizwe futhi ziphonswe, futhi i-dip-coated. nge-refractory coating (eqinisiwe) , ebushelelezi futhi ephefumulayo) futhi yomisiwe, ingcwatshwa esihlabathini esomile se-quartz futhi ingaphansi kwemodeli yokudlidliza ye-3-dimensional. Insimbi encibilikisiwe ithululelwa ebhokisini lesihlabathi elibunjwa ngaphansi kwengcindezi engalungile, ukuze imodeli yezinto ze-polymer ifudumale futhi iqhume, bese ikhishwa. Indlela entsha yokulingisa esebenzisa insimbi ewuketshezi ukuze imiselele inqubo yesikhathi esisodwa yokubunjwa kwesikhunta eyakhiwe ngemva kokupholisa nokuqiniswa ukuze kukhiqizwe ukulingwa. Ukukhipha igwebu elilahlekile kunezici ezilandelayo: 1. Ukusakaza kungokwekhwalithi enhle nezindleko eziphansi; 2. Izinto ezisetshenziswayo azinqunyelwe futhi zifanele wonke amasayizi; 3. Ukunemba okuphezulu, indawo ebushelelezi, ukuhlanzwa okuncane, nomshini omncane; 4. Ukukhubazeka kwangaphakathi kuyancipha kakhulu futhi isakhiwo sokubunjwa siyathuthukiswa. Kuminyene; 5. Ingakwazi ukukhiqiza izinto ezinkulu nezinkulu; 6. Ilungele ukukhiqizwa kwenqwaba yama-castings afanayo; 7. Ilungele ukusebenza ngesandla kanye nokukhiqizwa komugqa wokuhlanganisa okuzenzakalelayo nokulawula ukusebenza; 8. Isimo sokukhiqiza somugqa wokukhiqiza sihlangabezana nezidingo zemingcele yezobuchwepheshe yokuvikelwa kwemvelo. ; 9. Ingathuthukisa kakhulu indawo yokusebenza kanye nezimo zokukhiqiza zomugqa wokukhiqiza wokuphonsa, inciphise umfutho wabasebenzi, futhi inciphise ukusetshenziswa kwamandla.
Incazelo Yomkhiqizo
Ukukhishwa kwegwebu elilahlekile kuwuhlobo olugcwele lokubunjwa kwepulasitiki eyigwebu kusetshenziswa isihlabathi esomile esingena-binder esihlanganiswe nobuchwepheshe be-vacuum. Amagama ayinhloko asekhaya athi "i-dry sand solid cast" kanye "negative pressure solid cast", okubizwa ngokuthi yi-EPC casting; amagama aphambili angaphandle yilawa: I-Lost Foam Process (USA), Inqubo ye-P0licast (Italy), njll. Ukukhishwa kwegwebu elilahlekile kungenye yezinqubo ezithuthuke kakhulu zokuphonsa emhlabeni. Kwaziwa njengokuthi "uguquko" emlandweni wokulingisa futhi kubizwa ngekhulu lama-21 ukulingisa okuluhlaza ekhaya naphesheya. Isimiso sokukhiqiza: Le ndlela iqala yenza isikhunta segwebu ngokuvumelana nezidingo zenqubo, futhi iyigcoke ngopende okhethekile omelana nokushisa okuphezulu. Ngemuva kokumisa, kufakwa ebhokisini lesihlabathi elikhethekile, bese ligcwaliswa ngesihlabathi esomile ngokuvumelana nezidingo zenqubo. Ihlanganiswe ngokudlidliza okuyizinhlangothi ezintathu futhi ivacuumed. Insimbi encibilikisiwe ithululelwa phansi, futhi ngalesi sikhathi imodeli iyahwamuka futhi inyamalale, futhi insimbi encibilikisiwe ithatha indawo yemodeli, iphindaphinda ukubunjwa okufana nemodeli yegwebu.
Ingabe ufuna ukuxoxa ngokuthi yini esingakwenzela yona?
