EPTS130 Umsekeli
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
Ubuchwepheshe bokukhipha igwebu obulahlekile ukuhlanganisa nokuhlanganisa amamodeli epulasitiki egwebu afanayo ngosayizi nokuma kokulingwa abe amaqoqo amamodeli. Ngemuva kokuxubha nge-refractory coating kanye nokomisa, bangcwatshwa esihlabathini esomile se-quartz futhi badlidlize ukuze bamise, futhi insimbi ewuketshezi ithululelwa ngaphansi kwezimo ezithile. , indlela yokugcwalisa imodeli nokuhlala endaweni yemodeli, ukuqinisa nokupholisa ukwenza ukusakaza okudingekayo. Kunamagama amaningi ahlukene okukhishwa kwegwebu elilahlekile. Amagama asemqoka asekhaya athi "i-dry sand solid mold casting" kanye "negative pressure solid mold casting", okubizwa ngokuthi yi-EPC casting. Amagama aphambili angaphandle yilawa: I-Lost Foam Process (USA), Inqubo ye-P0licast (Italy), njll.
Uma kuqhathaniswa nobuchwepheshe bokusakaza bendabuko, ubuchwepheshe bokuphonsa amagwebu obulahlekile bunezinzuzo ezingenakuqhathaniswa, ngakho-ke budunyiswa "njengobuchwepheshe bokusakaza bekhulu lama-21" kanye "noguquko oluluhlaza embonini yokusungula" yimibuthano yasekhaya neyangaphandle.
